A 529 plan is a tax-advantaged savings account designed for education expenses. Contributions are made with after-tax dollars (no federal deduction), but the account grows tax-free and qualified withdrawals for education expenses are completely tax-free. More than 30 states offer a state income tax deduction or credit for contributions to their state's 529 plan.

Qualified expenses include tuition, fees, books, supplies, and room and board at accredited colleges and universities. K-12 tuition (up to $10,000/year) also qualifies. Apprenticeship programs and student loan repayment (up to $10,000 lifetime per beneficiary) are also qualified uses. Non-qualified withdrawals are subject to income tax plus a 10% penalty on the earnings portion.

Yes — you can change the beneficiary to another member of the original beneficiary's family (siblings, parents, cousins, etc.) without tax consequences. If your child receives a scholarship or decides not to attend college, you can roll the funds to another family member's 529, use them for K-12 tuition, or roll up to $35,000 into a Roth IRA (subject to annual Roth contribution limits and a 15-year account seasoning requirement).

You can elect to treat a lump-sum 529 contribution as if it were made ratably over 5 years, allowing you to contribute up to $90,000 per beneficiary ($180,000 for married couples) in a single year without gift tax consequences. This is called the "superfunding" or "5-year election" and must be reported on Form 709. No additional gifts to the same beneficiary can be made during the 5-year period without gift tax implications.

Yes — 529 funds can be used for graduate and professional school (law school, medical school, MBA programs) at accredited institutions, just like undergraduate education. Tuition, fees, books, and room and board all qualify. There is no age limit on the beneficiary, so 529 plans can be used for adult education and career changes as well.

RSUs are taxed as ordinary income at vesting. The fair market value of the shares on the vesting date is included in your W-2 as compensation income, subject to federal income tax, Social Security tax (up to the wage base), and Medicare tax (including the 0.9% Additional Medicare Tax if applicable). Your cost basis in the shares equals the amount included in your W-2.

Most employers withhold at the IRS supplemental wage rate of 22% (or 37% for amounts above $1 million). If your actual marginal tax rate is higher than 22% — which is common for tech workers with significant RSU income — you will owe additional taxes at filing. To avoid underpayment penalties, you should either increase withholding on your regular paycheck or make quarterly estimated tax payments.

From a tax and risk management perspective, selling immediately after vesting is often the right choice. Your cost basis equals the vesting-date value, so there is no tax benefit to holding (you have already paid ordinary income tax on the full value). Holding concentrates your financial exposure to your employer — the same company that employs you. If you want to hold for long-term capital gains treatment, hold for more than 1 year after vesting.

If you hold RSU shares for more than 1 year after vesting, they become long-term capital gain property and can be donated to a charity or DAF at fair market value, avoiding capital gains tax on the appreciation since vesting. If you donate within 1 year of vesting, the deduction is limited to your cost basis (the vesting-date value). Planning the timing of donations around the 1-year holding period can maximize the charitable deduction.

RSUs are a promise to deliver shares at a future date (vesting date) and are taxed as ordinary income at vesting with no upfront cost to the employee. Stock options (ISOs and NSOs) give you the right to purchase shares at a fixed price (the exercise price) and have more complex tax treatment. RSUs are simpler and always have value (as long as the stock price is above zero); options only have value if the stock price exceeds the exercise price.

A Health Savings Account (HSA) offers three tax benefits: (1) contributions are tax-deductible, (2) the balance grows tax-free, and (3) withdrawals for qualified medical expenses are tax-free. No other account offers all three benefits simultaneously. After age 65, HSA funds can be withdrawn for any purpose (taxed as ordinary income, like a Traditional IRA).

The 2026 HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage. Individuals age 55 or older can contribute an additional $1,000 catch-up contribution. The OBBBA also expanded HSA eligibility to include bronze and catastrophic health plans starting in 2026.

In 2026, an HDHP must have a minimum deductible of approximately $1,700 (self-only) or $3,400 (family) and maximum out-of-pocket limits of approximately $8,500 (self-only) or $17,000 (family). The OBBBA also expanded eligibility to bronze and catastrophic ACA plans starting in 2026 — check with your plan administrator.

Yes — and this is the most powerful HSA strategy. Instead of leaving HSA funds in a low-interest cash account, invest them in index funds or ETFs for tax-free growth. Many HSA providers (Fidelity, Lively, HSA Bank) offer investment options. Paying current medical expenses out of pocket and letting the HSA grow invested is the optimal long-term approach.

Before age 65, non-medical HSA withdrawals are subject to income tax plus a 20% penalty. After age 65, non-medical withdrawals are taxed as ordinary income (like a Traditional IRA) with no penalty. This makes the HSA a powerful retirement account that also covers medical expenses tax-free.

A backdoor Roth IRA is a two-step process: (1) contribute to a non-deductible Traditional IRA (no income limit), then (2) immediately convert the Traditional IRA to a Roth IRA. Since the contribution was made with after-tax dollars, the conversion is tax-free. This allows high earners to access Roth IRA benefits regardless of income.

Anyone with earned income can use the backdoor Roth strategy, but it is most valuable for individuals who exceed the Roth IRA income limits: approximately $165,000 (single) or $246,000 (married filing jointly) in 2026. Below these limits, you can contribute directly to a Roth IRA without the backdoor process.

Yes. The backdoor Roth IRA is a legal strategy explicitly acknowledged by Congress and the IRS. It has been available since 2010 when income limits on Roth conversions were eliminated. The strategy remains fully available in 2026.

The pro-rata rule requires you to calculate the taxable portion of a Roth conversion based on the ratio of pre-tax IRA funds to total IRA funds. If you have existing pre-tax Traditional IRA money, converting only the non-deductible contribution will trigger taxes on a proportional share. The cleanest backdoor Roth requires having no pre-tax IRA funds.

The backdoor Roth contribution limit is the same as the regular IRA limit: $7,500 per person in 2026 ($8,500 if age 50 or older). A married couple can each do a backdoor Roth for a combined $15,000/year in tax-free contributions.

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.

You can deduct up to $2,500 in student loan interest per year as an above-the-line deduction (you do not need to itemize). The deduction phases out between approximately $80,000 and $95,000 AGI for single filers, and between $160,000 and $190,000 for married filing jointly in 2026. The deduction reduces your AGI, which can improve eligibility for other tax benefits.

No — the student loan interest deduction is an above-the-line deduction claimed on Schedule 1, which reduces your AGI regardless of whether you take the standard deduction or itemize. This makes it available to virtually all qualifying borrowers.

If your parents paid your student loan interest and you are claimed as their dependent, neither you nor your parents can deduct the interest. However, if your parents paid the interest but you are not their dependent, you can deduct it as if you paid it yourself — the IRS treats this as a gift from your parents to you, which you then used to pay the loan.

The loan must have been taken out solely to pay qualified higher education expenses (tuition, fees, room and board, books, supplies) for you, your spouse, or a dependent. Both federal and private student loans qualify. Loans from family members or employer plans generally do not qualify.

Yes — you can deduct the interest portion of your payments regardless of which repayment plan you are on. Your loan servicer will send you Form 1098-E each year showing the total interest paid. Even if your payments are low under an income-driven plan, any interest you do pay is deductible up to the $2,500 limit.

A Dependent Care FSA (DCFSA) is an employer-sponsored benefit that lets you set aside pre-tax dollars to pay for qualifying dependent care expenses. The annual contribution limit is $5,000 per household ($2,500 if married filing separately). Contributions reduce your taxable income for federal income tax, Social Security tax, and Medicare tax — making the effective savings 22-37% depending on your tax bracket.

Qualifying expenses include daycare, preschool, after-school programs, summer day camps, and in-home care (nanny or au pair) for children under age 13. Care for a spouse or dependent who is physically or mentally incapable of self-care also qualifies. Overnight camps, tutoring, and kindergarten tuition do not qualify.

Yes, but not on the same expenses. The $5,000 FSA contribution reduces the expense base available for the Child and Dependent Care Credit. If you have one child, the credit base is $3,000 — after the $5,000 FSA, there is no remaining base for the credit. With two or more children, the credit base is $6,000 — after the $5,000 FSA, $1,000 remains eligible for the credit.

Dependent Care FSAs are "use it or lose it" — unused funds at the end of the plan year are forfeited. Unlike Health FSAs, there is no $640 rollover option. Some employers offer a 2.5-month grace period. Carefully estimate your annual childcare costs before electing your contribution amount.

Yes — payments to a nanny, au pair, or in-home caregiver for a qualifying dependent qualify for the Dependent Care FSA. However, you must report the caregiver's Social Security number on your tax return, and if you pay a household employee more than $2,800/year (2026), you may have "nanny tax" obligations (employer FICA, unemployment insurance).

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.

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.

The One Big Beautiful Bill Act (OBBBA) creates a new federal income tax deduction for qualifying overtime wages paid under the Fair Labor Standards Act (FLSA). This means overtime pay received by W-2 employees for hours worked over 40 per week may be excluded from federal taxable income starting in 2026.

W-2 employees who receive overtime pay under the FLSA qualify. This includes hourly workers, nurses, tradespeople, construction workers, factory workers, and any employee who receives time-and-a-half for hours worked over 40 per week. Salaried exempt employees who do not receive FLSA overtime do not qualify.

No — the overtime deduction applies to FLSA-qualifying overtime paid to W-2 employees. Independent contractors and gig workers do not receive FLSA overtime and do not qualify for this deduction.

Savings depend on your total overtime pay and your marginal tax rate. A worker earning $15,000 in overtime at a 22% rate saves $3,300/year. A worker in the 24% bracket saves $3,600/year on the same overtime income.

Your employer must correctly report overtime pay on your W-2. IRS guidance on the specific form and line for claiming the deduction is pending. Uncle Kam will ensure the deduction is properly claimed on your 2026 tax return.
