The Retirement Plan Startup Credit (Form 8881) provides a tax credit for small businesses that establish a new qualified retirement plan (401(k), SEP-IRA, SIMPLE IRA, or defined benefit plan). Under SECURE 2.0, businesses with 50 or fewer employees can claim 100% of eligible startup costs up to $5,000/year for the first 3 years — a maximum of $15,000 in total credits.

Eligible startup costs include: plan setup and administration fees, employee education and enrollment costs, and costs to set up payroll integration. The credit covers 100% of these costs for businesses with 50 or fewer employees, and 50% for businesses with 51-100 employees. Businesses with more than 100 employees do not qualify.

Yes — SECURE 2.0 added a $500/year credit for plans that include automatic enrollment features. This credit is available for the first 3 years of the plan and stacks on top of the startup cost credit. A plan with automatic enrollment can generate up to $16,500 in total credits over 3 years ($15,000 startup + $1,500 auto-enrollment).

No — the startup credit is only available for new plans. If you already have a retirement plan and want to add features (like automatic enrollment), you may qualify for the auto-enrollment credit but not the startup cost credit. The plan must be established for the first time to qualify for the startup credit.

The best plan depends on your goals: a Safe Harbor 401(k) avoids discrimination testing and allows maximum contributions for owner-employees; a SIMPLE IRA is easier to administer but has lower contribution limits; a SEP-IRA is easy to set up but requires proportional contributions for all eligible employees. Uncle Kam can model the contribution and tax savings for each option based on your payroll.

The Qualified Business Income (QBI) deduction under Section 199A allows owners of pass-through businesses — sole proprietorships, S-Corps, LLCs, and partnerships — to deduct up to 23% of their qualified business income starting in 2026, permanently extended and enhanced under the OBBBA. The full deduction is available if taxable income is below approximately $197,300 (single) or $394,600 (married filing jointly).

Yes. S-Corp owners can claim the QBI deduction on their share of the S-Corp's qualified business income. However, W-2 wages paid to yourself as an S-Corp employee are not included in QBI — only the pass-through profit qualifies.

It depends on income. Consultants are classified as a "specified service trade or business" (SSTB), which means the QBI deduction phases out above approximately $197,300 (single) or $394,600 (married) in 2026. Below those thresholds, consultants get the full 23% deduction.

Yes — the OBBBA permanently extended and enhanced the QBI deduction, increasing it from 20% to 23% starting in 2026. It no longer faces a sunset date. This is one of the most significant permanent tax changes for self-employed individuals and pass-through business owners.

The basic calculation is 23% of your qualified business income, limited to the lesser of 23% of QBI or 50% of W-2 wages paid by the business (or 25% of W-2 wages plus 2.5% of qualified property). For most small business owners below the income thresholds, the calculation is simply 23% of net business income.

The Augusta Rule (IRC Section 280A(g)) allows homeowners to rent their personal residence for up to 14 days per year and receive the rental income completely tax-free — no reporting required on Schedule E. Business owners exploit this by renting their home to their own business for legitimate business meetings, retreats, or events. The business deducts the rental payment; the homeowner receives it tax-free.

The rental rate must be the fair market rate for comparable event space in your area — what a hotel or event venue would charge for a similar space. You should document the market rate with comparable venue quotes or rental listings. Charging an inflated rate is a red flag for the IRS. Typical rates range from $500 to $2,500/day depending on the size and location of the home.

You need: (1) a written rental agreement between you personally and your business, (2) a legitimate business purpose for each rental day (board meeting agenda, planning retreat notes, etc.), (3) evidence of fair market rental rate (comparable venue quotes), (4) a business check or ACH payment from the business to you personally, and (5) minutes or notes documenting the business activities conducted at the home.

No — the tax-free treatment only applies to the first 14 days of rental per year. If you rent your home to your business for more than 14 days, all rental income becomes taxable (reported on Schedule E), and you must allocate expenses between personal and rental use. The 14-day limit is absolute; exceeding it eliminates the tax-free benefit for the entire year.

Yes — the Augusta Rule works for any business structure (sole proprietorship, LLC, S-Corp, C-Corp). For S-Corp owners, the rental payment is a deductible business expense for the S-Corp and tax-free rental income for the shareholder. The strategy is particularly valuable for S-Corp owners because it moves money from the S-Corp (where it would be subject to income tax) to the owner (where it is tax-free under the 14-day rule).

The QBI deduction (Section 199A) allows owners of pass-through businesses (sole proprietorships, partnerships, S-Corps, and some trusts) to deduct up to 23% of their qualified business income from federal taxable income starting in 2026, permanently extended and enhanced under the OBBBA. Employees and C-Corp shareholders do not qualify.

SSTBs are businesses in fields like law, health, financial services, accounting, actuarial science, performing arts, consulting (in the narrow IRS sense), athletics, and brokerage services. For SSTB owners with income above the phase-out thresholds (approximately $197,300 single / $394,600 MFJ in 2026), the QBI deduction phases out completely. Below the threshold, SSTB owners get the full deduction. The "consulting" SSTB is narrowly defined — many business advisors and management consultants do not qualify as SSTBs.

For non-SSTB businesses, the deduction is limited to the greater of: (a) 50% of W-2 wages paid by the business, or (b) 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property. These limitations apply when taxable income exceeds approximately $197,300 (single) or $394,600 (MFJ) in 2026. Below these thresholds, the full 23% deduction applies without the W-2 wage limitation.

For S-Corp owners, the QBI deduction applies to the S-Corp's qualified business income — which is the net income after the owner's reasonable salary is deducted. The salary itself is not QBI. This creates a tension: a lower salary increases QBI (and the deduction) but also increases the W-2 wage limitation at higher income levels. Uncle Kam can model the optimal salary to maximize the combined QBI deduction and SE tax savings.

Yes — the OBBBA permanently extended and enhanced the QBI deduction, increasing it from 20% to 23% starting in 2026. It no longer faces a sunset date. This is one of the most significant permanent tax changes for self-employed individuals and pass-through business owners.

Self-employed individuals can choose from a SEP-IRA (up to 25% of net self-employment income, max $72,000 in 2026), a Solo 401(k) (up to ~$70,000 plus $7,500 catch-up if over 50), a SIMPLE IRA, or a Defined Benefit Plan (which can shelter $100,000+ annually for high earners). The Solo 401(k) is typically the best option for most self-employed individuals because it allows both employee deferrals and employer contributions.

In 2026, a Solo 401(k) allows up to $24,500 as an employee deferral (plus $7,500 catch-up if over 50) plus up to 25% of net self-employment income as an employer contribution, for a combined maximum of approximately $70,000 ($77,500 with catch-up). This is significantly higher than a SEP-IRA for most income levels.

Generally no — you cannot contribute to both a Solo 401(k) and a SEP-IRA for the same self-employment income in the same year. However, you can have a Solo 401(k) for your self-employment income and participate in an employer's 401(k) at a day job, though combined employee deferrals across all plans are capped at $24,500 in 2026.

You must establish a Solo 401(k) by December 31 of the tax year to make employee deferrals for that year. Employer profit-sharing contributions can be made up to the tax filing deadline (including extensions). A SEP-IRA, by contrast, can be established and funded up to the tax filing deadline.

No — retirement contributions reduce income tax but not self-employment tax. SE tax is calculated on net self-employment income before retirement contributions. However, the deduction for half of SE tax reduces your AGI, which in turn reduces the base on which retirement contribution limits are calculated.

The WOTC is a federal tax credit of $2,400–$9,600 per qualifying new hire for employers who hire individuals from certain target groups, including veterans, long-term unemployment recipients, SNAP recipients, ex-felons, and vocational rehabilitation referrals. The credit is a dollar-for-dollar reduction in federal income taxes.

To claim WOTC, you must submit IRS Form 8850 (Pre-Screening Notice) to your state workforce agency within 28 days of the employee's start date. The state agency certifies eligibility. You then claim the credit on IRS Form 5884 with your tax return.

Qualifying target groups include: veterans (especially disabled veterans), long-term TANF recipients, SNAP (food stamp) recipients, designated community residents, vocational rehabilitation referrals, ex-felons, SSI recipients, long-term unemployment recipients (27+ weeks), and summer youth employees in empowerment zones.

The standard WOTC credit is 40% of first-year wages up to $6,000 ($2,400 maximum). For long-term TANF recipients, the credit extends to the second year (total up to $9,000). For disabled veterans, the credit can reach $9,600. The employee must work at least 400 hours to qualify for the full credit.

Yes. There is no minimum size requirement — any employer that hires qualifying individuals and files the required forms is eligible. The WOTC is one of the most underutilized credits for small businesses, particularly in industries with high turnover like restaurants, retail, and hospitality.

A net operating loss occurs when your allowable tax deductions exceed your taxable income for the year. The excess loss can be carried forward to future tax years to offset up to 80% of taxable income in each future year. NOLs generated after 2017 can be carried forward indefinitely.

Under current law, most NOLs generated after 2017 cannot be carried back — they can only be carried forward. However, farming losses and certain insurance company losses are exceptions. During COVID (2020-2021), special 5-year carryback rules applied.

NOL carryforwards can offset up to 80% of taxable income in any given year. This means if you have $500,000 in taxable income, an NOL can reduce it to no less than $100,000 in that year. The remaining NOL continues to carry forward.

Yes — and this is a legitimate tax planning strategy. By timing large deductions (bonus depreciation, Section 179, cost segregation) in a high-income year, a business can intentionally generate an NOL that offsets income in future years when the business is more profitable.

NOL carryforwards generally do not transfer to the buyer in an asset sale. In a stock sale, the NOLs remain with the corporation but are subject to severe limitations under IRC §382 if there is a change in ownership of more than 50%. Proper planning before a sale is essential to preserve the value of NOL carryforwards.

The Child Tax Credit is $2,000 per qualifying child under age 17 in 2026, permanently extended under the OBBBA. Up to $1,700 of the credit is refundable (the Additional Child Tax Credit) for taxpayers with earned income above $2,500. The credit begins to phase out at $200,000 AGI for single filers and $400,000 for married filing jointly, reducing by $50 for every $1,000 of income above the threshold.

The child must be under age 17 at the end of the tax year, a U.S. citizen or resident, claimed as your dependent, and have lived with you for more than half the year. The child must also have a valid Social Security number. There is no limit on the number of qualifying children you can claim.

Yes — up to $1,700 of the $2,000 credit is refundable as the Additional Child Tax Credit (ACTC). If your tax liability is less than the credit amount, you can receive the refundable portion as a cash refund. The refundable amount is calculated as 15% of earned income above $2,500, up to the $1,700 limit per child.

The credit phases out by $50 for every $1,000 (or fraction thereof) of AGI above $200,000 (single) or $400,000 (MFJ). At $440,000 MFJ, the credit is fully phased out for two children. Reducing AGI through retirement contributions, HSA contributions, or business deductions can preserve or increase the credit.

Yes — these are two separate credits. The Child Tax Credit ($2,000/child) is based on having a qualifying child under 17. The Child and Dependent Care Credit (up to $1,050 for one child, $2,100 for two or more) is based on childcare expenses paid so you can work. Both can be claimed in the same year for the same child.

The Residential Clean Energy Credit (formerly the Investment Tax Credit) allows homeowners to claim 30% of the cost of a solar panel system as a federal tax credit. The 30% rate applies to systems installed through 2032, stepping down to 26% in 2033 and 22% in 2034. The credit covers the cost of panels, inverters, mounting hardware, wiring, and installation labor.

No — the Residential Clean Energy Credit is non-refundable, meaning it can reduce your tax liability to zero but cannot generate a refund. However, any unused credit carries forward to future tax years indefinitely until fully used. If your tax liability is less than the credit amount, you will use the remainder in subsequent years.

The Residential Clean Energy Credit applies to your primary or secondary residence. For rental properties, the Investment Tax Credit (ITC) applies instead, which also provides a 30% credit but is claimed as a business credit. Rental property solar installations can also be depreciated, generating additional deductions beyond the credit.

In addition to solar, the Residential Clean Energy Credit covers wind turbines, geothermal heat pumps, battery storage systems (10 kWh minimum), and fuel cells. The Energy Efficient Home Improvement Credit (25C) provides separate credits for insulation, windows, doors, heat pumps, and electric panel upgrades — up to $3,200/year.

Yes — standalone battery storage systems with a capacity of at least 10 kWh qualify for the 30% Residential Clean Energy Credit starting in 2023, even if not paired with solar panels. This is a significant expansion from prior law, which required battery storage to be charged by solar to qualify.

The personal Clean Vehicle Credit (§30D) for new EVs was repealed under the OBBBA for vehicles purchased after December 31, 2025. However, the Commercial Clean Vehicle Credit (§45W, Form 8936) for business-use EVs remains available at up to $7,500 for vehicles under 14,000 lbs. If you are buying an EV for business use, the commercial credit still applies. Book a call to confirm eligibility for your specific vehicle and use case.

To qualify for the full $7,500 credit, the vehicle must be a new plug-in electric vehicle with a battery capacity of at least 7 kWh, have a final assembly in North America, meet critical mineral and battery component sourcing requirements, and fall within MSRP limits ($55,000 for cars, $80,000 for SUVs and trucks). The IRS maintains a current list of qualifying vehicles at fueleconomy.gov.

Yes — starting in 2024, you can transfer the Clean Vehicle Credit to the dealer at the point of sale, effectively receiving the credit as a discount on the purchase price. This is beneficial if your tax liability is less than $7,500 or if you want the benefit immediately rather than waiting until you file your return. The dealer then claims the credit from the IRS.

Businesses can claim the Commercial Clean Vehicle Credit (Form 8936) for EVs used in business, which provides up to $7,500 for vehicles under 14,000 lbs GVWR and up to $40,000 for larger commercial vehicles. Unlike the personal credit, the commercial credit has no income limits and no MSRP caps. Businesses can also combine the credit with Section 179 expensing and bonus depreciation.

The personal Clean Vehicle Credit is non-refundable — it can reduce your tax liability to zero but cannot generate a refund. However, if you transfer the credit to the dealer at purchase, you receive the full benefit regardless of your tax liability. The Commercial Clean Vehicle Credit for businesses is also non-refundable but can be carried back 1 year or forward 20 years.

The Energy Efficient Home Improvement Credit (Section 25C) provides a 30% credit for qualifying energy efficiency improvements to your primary residence. The annual credit limit is $3,200 total, with sub-limits: $2,000 for heat pumps and biomass stoves, $1,200 for insulation, windows, doors, and energy audits (with further per-item limits). The credit resets each year through 2032.

Qualifying improvements include: heat pumps (air-source and geothermal), heat pump water heaters, biomass stoves and boilers, exterior windows and skylights (must meet Energy Star Most Efficient criteria), exterior doors (must meet Energy Star requirements), insulation and air sealing materials, and home energy audits. Central air conditioners and gas furnaces may also qualify if they meet efficiency thresholds.

Yes — unlike the old Nonbusiness Energy Property Credit which had a lifetime limit, the new Section 25C credit has an annual limit that resets each year. You can claim up to $3,200 in credits per year through 2032, allowing you to spread energy upgrades across multiple years and maximize the total credits claimed.

No — the Section 25C credit applies only to your primary residence. Rental properties do not qualify for this credit. However, energy efficiency improvements to rental properties can be depreciated as capital improvements, and in some cases may qualify for bonus depreciation or Section 179 expensing if the property is used in a trade or business.

Yes — the Section 25C (Energy Efficient Home Improvement Credit) and the Section 25D (Residential Clean Energy Credit for solar) are separate credits with separate limits. You can claim both in the same year. For example, installing solar ($10,500 credit) and a heat pump ($2,000 credit) in the same year would generate $12,500 in total federal tax credits.

A Donor-Advised Fund (DAF) is a charitable giving account sponsored by a public charity (such as Fidelity Charitable or Schwab Charitable). You contribute cash, securities, or other assets to the DAF, receive an immediate tax deduction for the full contribution, and then recommend grants to qualified charities over time. The assets grow tax-free inside the DAF until distributed.

Cash contributions to a DAF are deductible up to 60% of AGI. Contributions of appreciated securities are deductible at fair market value up to 30% of AGI. Excess contributions carry forward for up to 5 years. Unlike private foundations, DAFs have no minimum distribution requirement.

Bunching means contributing multiple years of planned charitable giving into a DAF in a single year to exceed the standard deduction threshold and itemize. For example, instead of donating $10,000/year for 5 years (which may not exceed the standard deduction), you contribute $50,000 in Year 1 to a DAF, take the full itemized deduction, and then distribute $10,000/year to charities from the DAF over the following 5 years.

Yes — and this is one of the most powerful aspects of a DAF. You can contribute long-term appreciated stock directly to the DAF, deduct the full fair market value (up to 30% of AGI), and avoid paying capital gains tax on the appreciation. The DAF can then sell the stock tax-free and invest the proceeds for future charitable distributions.

A DAF is simpler and cheaper to establish (no legal fees, no IRS approval), has no minimum distribution requirement, offers higher deduction limits, and provides anonymity for grants. A private foundation offers more control (you can hire family members, make program-related investments, and set your own grant criteria) but requires 5% annual distributions, has lower deduction limits, and faces excise taxes on investment income.

Yes. You can donate long-term appreciated stock (held more than 1 year) directly to a qualified charity or Donor-Advised Fund and deduct the full fair market value on the date of the gift — up to 30% of AGI. You also avoid paying capital gains tax on the appreciation. This is almost always more tax-efficient than selling the stock and donating cash.

When you donate appreciated stock, you get two tax benefits: (1) a charitable deduction for the full fair market value, and (2) you avoid capital gains tax on the appreciation. When you donate cash, you only get the charitable deduction. For stock with large embedded gains, the difference can be tens of thousands of dollars.

You can donate publicly traded stocks, mutual funds, ETFs, bonds, real estate, private company stock, cryptocurrency, and other appreciated assets. The deduction rules vary by asset type: publicly traded securities are deductible at fair market value; private company stock and real estate require a qualified appraisal; cryptocurrency is treated like property.

Contributions of long-term appreciated capital gain property to public charities are deductible up to 30% of AGI. Contributions to private foundations are limited to 20% of AGI. Excess contributions carry forward for up to 5 years. Cash donations to public charities are deductible up to 60% of AGI.

Yes. The IRS treats cryptocurrency as property, so donating appreciated crypto directly to a qualified charity or DAF allows you to deduct the fair market value and avoid capital gains tax on the appreciation — the same as donating appreciated stock. The charity or DAF can then sell the crypto tax-free.

Tax-loss harvesting is the practice of selling investments at a loss to offset capital gains from other investments, reducing your overall tax liability. The harvested losses first offset capital gains dollar-for-dollar. If losses exceed gains, up to $3,000 of excess losses can offset ordinary income per year. Remaining losses carry forward indefinitely to future years.

The wash-sale rule disallows a loss deduction if you buy the same or "substantially identical" security within 30 days before or after the sale. To avoid triggering the rule, you can immediately reinvest in a similar but not identical security (e.g., sell a Vanguard S&P 500 ETF and buy a Fidelity S&P 500 ETF), wait 31 days before repurchasing, or use the loss to rebalance your portfolio.

No — losses in tax-deferred accounts (IRA, 401(k)) cannot be harvested because all gains and losses inside those accounts are tax-deferred. Tax-loss harvesting only applies to taxable brokerage accounts. This is one reason why it can be beneficial to hold more volatile assets in taxable accounts where losses can be harvested.

Yes — and cryptocurrency has a significant advantage: the wash-sale rule does not currently apply to crypto (it applies only to "securities" under the tax code, and crypto is classified as property). This means you can sell crypto at a loss, immediately repurchase the same coin, and still claim the loss deduction. This may change with future legislation.

Capital losses first offset capital gains of the same type (short-term losses offset short-term gains; long-term losses offset long-term gains). Excess losses can offset gains of the other type. After offsetting all capital gains, up to $3,000 of net capital losses can offset ordinary income per year. Remaining losses carry forward indefinitely.

When you inherit an asset, your cost basis is "stepped up" to the fair market value on the date of the decedent's death (or an alternate valuation date 6 months later). This means all appreciation during the decedent's lifetime is permanently erased for capital gains purposes. If you sell the asset immediately after inheriting it, you owe zero capital gains tax on the lifetime appreciation.

Most capital assets that pass through an estate receive a step-up: stocks, bonds, mutual funds, real estate, business interests, and collectibles. Assets held in IRAs and 401(k)s do not receive a step-up — they are subject to ordinary income tax when withdrawn. Assets in irrevocable trusts may or may not receive a step-up depending on how the trust is structured.

In community property states (California, Texas, Arizona, Nevada, Washington, Idaho, Louisiana, New Mexico, Wisconsin), both halves of community property receive a step-up in basis when one spouse dies — not just the deceased spouse's half. This is a significant advantage over common law states, where only the deceased spouse's share receives the step-up.

For very large embedded gains, holding appreciated assets until death can eliminate the capital gains tax entirely through the step-up in basis. However, this strategy must be weighed against estate tax exposure (if the estate exceeds the exemption), liquidity needs, and the opportunity cost of holding a concentrated position. Uncle Kam can model the tradeoffs for your specific situation.

Yes — donating appreciated assets to a qualified charity or Donor-Advised Fund eliminates the capital gains tax and generates a charitable deduction for the full fair market value. This is often more tax-efficient than holding until death (which avoids capital gains but may trigger estate tax) or selling and donating cash (which triggers capital gains before the donation).

No — as of 2026, the wash-sale rule (which disallows a loss if you repurchase the same security within 30 days) does not apply to cryptocurrency. The IRS classifies crypto as property, not a security, so you can sell crypto at a loss and immediately repurchase the same coin without losing the tax deduction. This may change with future legislation, but for now it is a significant advantage over stock tax-loss harvesting.

The IRS treats cryptocurrency as property. Selling, trading, or spending crypto triggers a capital gain or loss equal to the difference between your cost basis and the sale price. Short-term gains (held less than 1 year) are taxed as ordinary income; long-term gains (held more than 1 year) are taxed at 0%, 15%, or 20% depending on your income. Receiving crypto as payment for services is taxed as ordinary income.

Net capital losses (including crypto losses) can offset up to $3,000 of ordinary income per year. Losses above $3,000 carry forward to future years to offset future capital gains or additional ordinary income. There is no limit on how many years losses can carry forward.

Trading one cryptocurrency for another (e.g., Bitcoin for Ethereum) is a taxable event — you must report the gain or loss on each trade. Using crypto to purchase goods or services is also taxable. Simply holding crypto (HODLing) is not a taxable event. Receiving crypto as a gift is not taxable until you sell it (your basis is the donor's basis or the fair market value on the date of the gift, whichever is lower).

You must track: the date of each acquisition, the cost basis (purchase price plus fees), the date of each sale or exchange, the sale proceeds, and the resulting gain or loss. For large portfolios with many transactions, crypto tax software (CoinTracker, Koinly, TaxBit) can automate this tracking. The IRS requires you to report all crypto transactions, and exchanges are required to issue 1099s for transactions above certain thresholds.

As a sole proprietor, you pay 15.3% self-employment tax on all net profits. As an S-Corp owner, you pay yourself a reasonable salary (subject to payroll taxes) and take the remaining profit as a distribution — which is not subject to self-employment tax. On $150,000 in profit, this can save $10,000–$20,000/year.

The IRS requires S-Corp owner-employees to pay themselves a "reasonable compensation" — roughly what you would pay a third party to do your job. The IRS looks at industry benchmarks, the services you provide, and the profitability of the business. Underpaying yourself is a major audit trigger.

The S-Corp election typically makes financial sense when your net self-employment income exceeds $50,000–$60,000/year. Below that threshold, the administrative costs (payroll processing, additional tax filings) often exceed the SE tax savings.

Yes. An LLC can elect to be taxed as an S-Corp by filing IRS Form 2553. The LLC retains its legal structure while being treated as an S-Corp for tax purposes. This is one of the most common and effective tax elections for small business owners.

S-Corps require running payroll, filing quarterly payroll tax returns, and paying additional accounting fees. They also have restrictions: no more than 100 shareholders, all shareholders must be US citizens or residents, and only one class of stock is allowed. For most small businesses, the tax savings far outweigh these administrative requirements.

A home office must be used regularly and exclusively for business — a dedicated room or clearly defined space used only for work. A kitchen table where you occasionally work does not qualify. The space must be your principal place of business or where you meet clients.

No. The Tax Cuts and Jobs Act of 2017 eliminated the home office deduction for W-2 employees through 2025. Only self-employed individuals, freelancers, and business owners can currently claim the home office deduction.

You can deduct the business-use percentage of your internet bill. If your home office is 10% of your home's square footage, you can deduct 10% of your internet costs. If you use the internet exclusively for business (a separate business line), you can deduct 100%.

The simplified method allows you to deduct $5 per square foot of your home office, up to 300 square feet ($1,500 maximum). It is easier to calculate but often produces a smaller deduction than the actual expense method for most homeowners.

The home office deduction is not an automatic audit trigger. The IRS does scrutinize it, but a properly documented, legitimate home office is fully defensible. The key is the "exclusive use" requirement — the space must be used only for business, not as a guest room or general living area.

A single-member LLC is taxed as a sole proprietorship by default (Schedule C). A multi-member LLC is taxed as a partnership by default (Form 1065). An LLC can elect to be taxed as an S-Corp (Form 2553) or C-Corp (Form 8832). The S-Corp election is the most common tax optimization strategy for profitable LLCs, as it reduces self-employment tax on the portion of income taken as distributions rather than salary.

The S-Corp election typically makes sense when net profit exceeds $80,000-$100,000/year. Below that level, the administrative costs of running an S-Corp (payroll processing, additional tax filings, state fees) often exceed the SE tax savings. The breakeven point depends on your state, the cost of payroll services, and the reasonable salary for your role.

The IRS requires S-Corp owner-employees to pay themselves a "reasonable compensation" — what you would pay an unrelated employee to perform the same services. The IRS looks at industry compensation data, the company's profitability, and the owner's duties. Setting the salary too low is the most common S-Corp audit trigger. Uncle Kam can help you determine a defensible reasonable salary for your specific business.

Yes — you can elect S-Corp status for an existing LLC by filing Form 2553 with the IRS. The election can be made at any time during the year for the following year, or within the first 2.5 months of the tax year for the current year. Some states require a separate state-level S-Corp election. The LLC remains an LLC for state law purposes; the S-Corp election only changes the federal (and sometimes state) tax treatment.

Disadvantages include: (1) additional administrative burden (payroll processing, quarterly payroll tax deposits, W-2 issuance, Form 1120-S filing), (2) additional cost ($500-$2,000/year for payroll services and tax preparation), (3) S-Corp restrictions (no more than 100 shareholders, only one class of stock, no foreign shareholders), and (4) some states do not recognize the S-Corp election and tax LLCs as corporations regardless.

A Solo 401(k) is a retirement plan for self-employed individuals with no full-time employees other than a spouse. It allows contributions in two capacities: as an employee (up to $24,500 in 2026, plus $7,500 catch-up if 50+) and as an employer (up to 25% of net self-employment income), with a combined limit of approximately $70,000 in 2026.

The total Solo 401(k) contribution limit is approximately $70,000 in 2026 ($77,500 if age 50 or older). This includes up to $24,500 in employee deferrals plus employer profit-sharing contributions of up to 25% of net self-employment income (after the SE tax deduction).

A Solo 401(k) must be established by December 31 of the tax year for which you want to make contributions. Employee deferrals must also be made by December 31. Employer profit-sharing contributions can be made up to the tax filing deadline (including extensions).

Yes, but the employee deferral limit ($24,500 in 2026) applies across all 401(k) plans combined. If you contribute $24,500 to your employer's 401(k), you cannot make additional employee deferrals to your Solo 401(k). However, you can still make employer profit-sharing contributions to the Solo 401(k).

A Solo 401(k) generally allows higher contributions for most self-employed individuals because it includes both employee deferrals and employer contributions. A SEP-IRA is limited to 25% of net self-employment income (no employee deferral component). For someone earning $100,000 net, a Solo 401(k) allows $46,000 vs. $18,587 for a SEP-IRA.

A Simplified Employee Pension (SEP-IRA) is a retirement account for self-employed individuals and small business owners. It allows contributions of up to 25% of net self-employment income (after the SE tax deduction), with a maximum of $72,000 in 2026. Any self-employed person with net income can open a SEP-IRA.

A SEP-IRA can be opened and funded up to the tax filing deadline, including extensions. For a sole proprietor, this means you can open a SEP-IRA and make a 2026 contribution as late as October 15, 2027 (with an extension). This makes it the most flexible retirement plan for last-minute tax planning.

The SEP-IRA contribution limit is 25% of net self-employment income (after deducting half of self-employment tax), up to a maximum of $72,000 in 2026. For a freelancer with $100,000 in net income, the maximum SEP-IRA contribution is approximately $18,587.

For most self-employed individuals, a Solo 401(k) allows higher contributions because it includes both employee deferrals and employer contributions. A SEP-IRA is simpler to administer and can be opened after year-end. If you want maximum contributions and are willing to manage payroll, the Solo 401(k) wins. If simplicity is the priority, the SEP-IRA is excellent.

Yes. SEP-IRA contributions do not affect your ability to contribute to a Roth IRA (subject to income limits) or use the backdoor Roth strategy. However, having pre-tax SEP-IRA funds can complicate backdoor Roth conversions due to the pro-rata rule. Uncle Kam helps clients navigate this interaction.

Self-employed individuals pay 15.3% self-employment tax (covering Social Security and Medicare) on net self-employment income. The IRS allows you to deduct 50% of the SE tax paid as an above-the-line deduction on Schedule 1 of your Form 1040. This deduction reduces your adjusted gross income and is available regardless of whether you itemize.

The deduction equals 50% of your total SE tax. For someone with $100,000 in net SE income, the SE tax is approximately $14,130, and the deduction is $7,065. At a 24% marginal rate, this saves $1,696 in income taxes — on top of the SE tax already paid.

No. The SE tax deduction is an above-the-line deduction, meaning it reduces your adjusted gross income (AGI) regardless of whether you take the standard deduction or itemize. It is one of the most straightforward and universally available deductions for self-employed individuals.

The most effective way to reduce SE tax is to elect S-Corp status. As an S-Corp, you pay SE tax (payroll taxes) only on your reasonable salary — not on the full profit. Distributions above the salary are not subject to SE tax. For someone earning $150,000+ net, this can save $10,000–$20,000/year.

No. They are separate deductions. The SE tax deduction (50% of SE tax paid) reduces your AGI. The QBI deduction (up to 23% of qualified business income under the OBBBA) is a separate below-the-line deduction that reduces taxable income. Both are available to self-employed individuals and can be claimed simultaneously.
