What Federal Tax Changes Affect You in 2026?

For the 2026 tax year, Michigan business owners and high-income professionals face a dramatically reshaped federal tax landscape. The One Big Beautiful Act, signed into law on July 4, 2025, fundamentally transformed how businesses deduct capital investments and structure their tax planning. This legislation removed the “sunset anxiety” that plagued corporate planning for years by making key provisions permanent rather than temporary.

Permanent Bonus Depreciation (100% Deduction)

One of the most significant changes for 2026 is the permanence of 100% bonus depreciation. Under prior law, this benefit was set to expire, creating uncertainty for capital-intensive businesses. Now, businesses can immediately deduct 100% of the cost of qualified property placed in service during 2026. This applies to machinery, equipment, and certain real property improvements—a massive advantage for manufacturers, construction companies, and technology firms operating in Michigan.

Example Scenario: A Michigan manufacturing company purchases $500,000 in new equipment in 2026. Under 100% bonus depreciation, they can deduct the entire $500,000 immediately, reducing 2026 taxable income by $500,000. This creates an estimated $150,000 to $210,000 in tax savings (depending on the company’s effective tax rate), improving cash flow significantly.

Qualified Business Income (QBI) Deduction Made Permanent

The 20% QBI deduction, available to business owners, self-employed professionals, and real estate investors, is now permanently available for 2026 and beyond. This deduction allows pass-through business entities (S-Corps, LLCs, partnerships) to deduct up to 20% of qualified business income, subject to income limitations and W-2 wage thresholds.

For Michigan business owners with net business income of $300,000, the QBI deduction could reduce taxable income by $60,000. At a combined federal and state effective tax rate of 35%, this creates $21,000 in annual tax savings—a critical benefit that’s now permanent.

R&D Expensing Changes (100% Immediate Deduction)

Prior tax law required companies to amortize research and development costs over five years—a significant burden for tech, biotech, and pharmaceutical companies in Michigan’s growing innovation hubs. The OBBBA repealed this requirement, allowing businesses to deduct 100% of domestic R&D expenditures immediately in the year incurred. This change alone is projected to save S&P 500 companies billions in taxes and unlock significant capital for reinvestment.

How Does the Expanded SALT Deduction Impact Michigan Homeowners?

Under the 2017 Tax Cuts and Jobs Act, the state and local tax (SALT) deduction was capped at $10,000 for all filers. For Michigan homeowners in higher-income brackets or those living in expensive neighborhoods, this created a painful “tax on taxes”—paying federal taxes on state taxes already paid. The OBBBA increased the SALT cap to $40,000 for married couples filing jointly and $20,000 for married filing separately, effective through 2029.

Who Benefits Most from SALT Expansion?

Michigan homeowners with significant property tax bills benefit substantially. For example, a couple in an upscale Detroit neighborhood paying $15,000 annually in property taxes plus $25,000 in Michigan state income taxes now can deduct $40,000 of combined state and local taxes, reducing federal taxable income accordingly. In 2025, they would have been limited to $10,000, leaving $30,000 of taxes undeductible. This expansion alone could save such a household $10,500 in federal income taxes (assuming a 35% combined federal-state marginal rate).

The expansion particularly benefits high-income professionals and business owners in Michigan’s urban centers—Detroit, Ann Arbor, Grand Rapids—where property values and tax bills are highest.

Itemizing vs. Standard Deduction

Not all taxpayers will benefit. The standard deduction slightly increased for 2026, and some Michigan homeowners will still benefit more from taking the standard deduction rather than itemizing, even with the expanded SALT deduction. High-income homeowners with substantial mortgage interest and charitable contributions will see the most benefit from itemizing and utilizing the expanded SALT deduction.

What Is Michigan’s New 24% Cannabis Wholesale Tax?

On January 1, 2026, Michigan implemented a 24% wholesale cannabis tax—a state-specific tax that applies on top of existing federal and state sales taxes. This tax was created during Michigan’s budget negotiations in late 2025 and applies specifically to cannabis products, distinguishing Michigan from other legal states with different cannabis tax structures.

What Transactions Are Subject to the 24% Wholesale Tax?

The Michigan 24% wholesale cannabis tax applies to three main transaction types:

• First sale or transfer: When a cannabis wholesaler sells product to a retailer, the 24% tax is assessed on the wholesale price before retail markup.
• Self-cultivated product: When a cannabis retailer cultivates and processes cannabis for retail sale, the 24% tax applies to the fair market value of that product.
• Medical provisioning center transfers: Sales or transfers from medical cannabis provisioning centers to adult-use retailers are subject to the 24% wholesale tax.

Economic Impact on Cannabis Businesses

Example: A Michigan cannabis wholesaler sells $100,000 in product to retailers. The 24% wholesale tax adds $24,000 in costs. If the retailer operates on typical 40-50% gross margins, this $24,000 tax must be absorbed or passed to consumers, reducing profitability by approximately 10-15% for wholesalers and wholesaler-retailers.

Michigan State Senator Jonathan Lindsey introduced bipartisan legislation in March 2026 to repeal this tax, arguing it creates unnecessary burden on the legal cannabis market and may inadvertently strengthen the black market. The proposal has gained traction due to economic concerns about cannabis business viability. However, as of March 11, 2026, the tax remains in effect, and cannabis business owners should budget for it in 2026 planning.

What Are the Self-Employment Tax Implications of 2026 Tax Changes?

For Michigan self-employed professionals and 1099 contractors, the 2026 tax year introduces nuanced changes that affect how self-employment income is calculated and taxed. The baseline self-employment tax rate—combining Social Security and Medicare taxes—remains 15.3%, but new rules around deductions and income calculation create planning opportunities and compliance challenges.

Qualified Tips Deduction Limitations

The OBBBA introduced a new deduction for qualified tips in certain industries. For self-employed individuals (such as independent contractors in service industries), the rules are more complex than for wage employees. The IRS clarified in updated guidance that self-employed tip deductions are limited by the net income from the trade or business in which tips were received, after deducting business expenses. Additionally, self-employed individuals can deduct a maximum of $25,000 in qualified tips.

Self-employed restaurant owners, musicians, and other service professionals earning significant tip income should work with self-employed tax specialists to properly document and claim this deduction.

Maximizing Retirement Contributions to Reduce SE Tax

One of the most effective strategies for self-employed professionals in 2026 is maximizing retirement contributions. Using our Self-Employment Tax Calculator, self-employed individuals can determine how much to contribute to SEP-IRAs, Solo 401(k)s, or other retirement vehicles to reduce both income tax and self-employment tax liability.

Example: A Michigan consultant earns $150,000 in self-employment income. Contributing the maximum $24,500 to a Solo 401(k) reduces taxable self-employment income to $125,500. This saves approximately $3,677 in self-employment taxes (15.3% of the reduction), plus standard income tax savings of $7,350+ (at a 29.6% combined federal-state marginal rate). Total first-year tax savings exceed $11,000 on a $24,500 investment in retirement savings.

How Should Business Owners Plan for 2026 Tax Law Changes?

The permanence of key tax provisions in the OBBBA creates a multi-year planning opportunity for Michigan business owners. Unlike prior years where temporary provisions created uncertainty, 2026 allows confident long-term capital planning.

Strategy 1: Accelerate Capital Equipment Investments

With 100% bonus depreciation now permanent, Michigan manufacturers, construction companies, and professional service firms should evaluate accelerating equipment purchases into 2026. Equipment purchased and placed in service during 2026 generates immediate 100% deductions, creating significant tax savings with minimal cash flow impact.

This is particularly valuable for businesses evaluating equipment replacement cycles. Rather than spreading purchases across multiple years, concentrating purchases in 2026 and subsequent years creates larger, more valuable deductions in single tax years.

Strategy 2: Optimize Entity Structure for QBI Deduction

The permanent 20% QBI deduction creates incentives for business structure optimization. S-Corporations, LLCs, and partnerships have different mechanics for calculating QBI deductions. For business owners currently operating as sole proprietorships or partnerships, converting to an S-Corp or LLC may allow you to claim the QBI deduction while also reducing self-employment taxes through reasonable salary treatment.

This analysis requires professional guidance, as improper salary treatment triggers IRS penalties. Working with a tax entity structuring specialist is essential.

Strategy 3: Verify S-Corp Reasonable Salary Compliance

S-Corp owners frequently misclassify income as distributions rather than W-2 salary to avoid payroll taxes. However, the IRS aggressively audits S-Corps with unreasonably low salaries. For 2026, business owners should ensure their W-2 salary meets or exceeds reasonable compensation benchmarks for their industry and role. Reasonable compensation is generally defined as the amount a similar business would pay for similar services.

What Are the 2026 Retirement Account Changes?

While federal 2026 tax rates remained relatively stable, retirement account contribution limits increased modestly, creating opportunities for Michigan business owners and self-employed professionals to shelter income from taxation.

401(k) Contributions and Limits

The 2026 limit for 401(k) contributions is $24,500 for employees under 50, with an additional $7,500 catch-up contribution allowed for those 50 and older. For self-employed individuals operating Solo 401(k)s, contributions can exceed these limits through employer contributions (up to 25% of net self-employment income), making Solo 401(k)s exceptionally powerful tax-reduction vehicles.

Scenario: A Michigan consultant with $200,000 in self-employment income can contribute $24,500 as an employee deferral and approximately $37,000+ as an employer contribution to a Solo 401(k), totaling approximately $61,500 in tax-deferred retirement savings—reducing 2026 taxable income accordingly.

Trump Accounts: New Tax-Advantaged Savings for Children

The OBBBA introduced “Trump Accounts,” a new tax-advantaged savings vehicle for children born in 2025-2028. Each eligible child receives a one-time $1,000 contribution from the U.S. Treasury. Parents and guardians can contribute up to $5,000 annually per child (adjusted for inflation). These accounts function similarly to Roth IRAs after the child turns 18 and offer tax-free growth of eligible investments. Starting July 4, 2026, parents can begin opening Trump Accounts for eligible children.

This represents a meaningful long-term tax benefit for high-income Michigan families with young children. A newborn receiving the $1,000 Treasury contribution and $5,000 annual contributions from parents could accumulate approximately $95,000 by age 18 (assuming modest 5% annual returns).

Uncle Kam in Action: How Sarah Optimized Her Michigan Business Taxes for 2026

Client Profile: Sarah is a Michigan-based digital marketing consultant operating as a solo S-Corporation with approximately $250,000 in annual gross revenue. She owns real estate in an upscale Ann Arbor neighborhood with $28,000 in annual property taxes and $15,000 in Michigan state income taxes. Sarah had not optimized her tax structure since starting her business five years prior.

The Challenge: Sarah was frustrated by large tax bills despite her professional income. Her original structure involved a C-Corporation, which created double taxation. She was missing out on the QBI deduction and wasn’t taking advantage of bonus depreciation on office equipment. Additionally, her homeowner property and income taxes were largely non-deductible under the old $10,000 SALT cap.

The Uncle Kam Solution: We implemented three critical changes for 2026:

• Converted her C-Corporation to an S-Corporation, allowing her to claim the 20% QBI deduction on her qualified business income, which was previously unavailable.
• Evaluated her home office and equipment situation. She purchased a new computer workstation ($8,000) and office furniture ($5,000), which now qualifies for 100% bonus depreciation, creating a $13,000 immediate deduction.
• Opened a Solo 401(k) and made the maximum $24,500 employee deferral contribution plus calculated employer contributions, reducing her 2026 taxable income by approximately $61,000.

The Results: Sarah’s 2026 estimated tax liability decreased by approximately $28,500 compared to her 2025 return, despite earning the same income. Key savings included:

• QBI Deduction: $50,000 × 20% = $10,000 deduction = ~$2,960 federal tax savings
• Equipment Depreciation: $13,000 immediate deduction = ~$3,835 tax savings
• Retirement Contributions: $61,000 deduction = ~$18,000 combined federal and state tax savings
• SALT Deduction Expansion: Now able to deduct additional $30,000 in property and income taxes = ~$8,850 tax savings

First-Year ROI: Sarah invested $2,500 in professional tax planning and paid $3,200 in compliance fees. Her first-year tax savings were $28,500, creating a remarkable 890% ROI on her planning investment. She also built $61,000 in retirement savings, further securing her financial future.

Sarah’s story demonstrates that proper tax advisory and planning around 2026 changes creates life-changing financial results. Most business owners are unaware of opportunities like the permanent QBI deduction, expanded SALT cap, and retirement contribution strategies that can save tens of thousands annually.

Next Steps

Now that you understand the major 2026 tax changes affecting Michigan residents, it’s time to take action. Here are your immediate next steps:

• Conduct a 2026 tax projection: Meet with a tax professional to model your 2026 tax liability under current law and identify specific deductions you may be missing. Use projections to guide capital purchase and retirement contribution decisions before December 31, 2026.
• Review your entity structure: Evaluate whether your current business structure (sole proprietorship, LLC, S-Corp, C-Corp) optimally captures QBI deductions and minimizes self-employment taxes. This review typically pays for itself within a single tax year.
• Maximize retirement contributions: Establish or maximize contributions to 401(k)s, IRAs, or Solo 401(k)s to reduce 2026 taxable income. Contributions made by April 15, 2027 can be deducted on your 2026 return.
• Plan for Michigan’s cannabis tax: If you operate in the cannabis industry, consult with specialized tax advisors to understand 2026 tax treatment and monitor the status of the proposed repeal legislation.
• Schedule ongoing tax planning: Don’t wait until tax season to address 2026 planning. Proactive quarterly or monthly tax strategy reviews ensure you’re capturing deductions and adjusting your plan as circumstances change.

Frequently Asked Questions

1. Are the 2026 tax changes permanent, or will they expire?

The major provisions in the OBBBA (bonus depreciation, QBI deduction, R&D expensing) are now permanent and won’t expire. However, the SALT deduction cap increase is set to sunset after 2029 unless Congress extends it. The OBBBA also eliminated the “sunset anxiety” that previously plagued business planning, allowing confident long-term strategy development.

2. Will the Michigan cannabis tax repeal affect my 2026 taxes?

As of March 11, 2026, Michigan’s 24% wholesale cannabis tax remains in effect. Cannabis business owners must account for it in their 2026 taxes. If the repeal (proposed by Senator Lindsey) passes later in 2026, it could affect Q3 or Q4 operations but would likely apply prospectively. Consult with cannabis tax specialists to understand your specific situation and monitor legislative developments.

3. Can I still claim the QBI deduction if I’m an employee?

No. The 20% QBI deduction is available exclusively to business owners operating as pass-through entities (S-Corporations, LLCs, partnerships) or sole proprietors. W-2 employees cannot claim the QBI deduction, though they may benefit from other deductions or the standard deduction increase.

4. What is the deadline to establish a Solo 401(k) for 2026 tax deductions?

Solo 401(k) plans must be established by December 31, 2026 to allow contributions for the 2026 tax year. However, contributions can be made as late as April 15, 2027 (or October 15, 2027 with an extension). Working with a tax planning professional ensures timely establishment and proper documentation.

5. How much should I pay myself as an S-Corp salary to avoid IRS scrutiny?

“Reasonable compensation” varies by industry, business size, and your specific role. For professional service businesses, reasonable salary is typically 50-100% of net business income. For other businesses, benchmarking studies specific to your industry are essential. The IRS aggressively audits S-Corps with disproportionately low salaries relative to distributions. Consult with tax professionals to determine appropriate salary levels for your specific situation.

6. Do I benefit from the SALT deduction expansion even if I don’t own a home?

The SALT deduction includes state and local income taxes, sales taxes, and property taxes. Even renters can claim deductions for state and local income taxes and, in some states, sales taxes. However, the benefit is greatest for homeowners in high-tax states like Michigan with significant property tax bills. Renters should consult with tax professionals to understand their specific SALT deduction opportunity.

7. What documents do I need to claim the new qualified tips deduction?

For self-employed individuals claiming qualified tips deductions, maintain detailed records of tip income, including daily logs, credit card receipts, and cash accounting. The IRS revised guidance limits self-employed tip deductions to net income from the trade or business in which tips were earned, after all business expense deductions. Documentation is critical—the IRS increases audit rates for businesses claiming substantial tip deductions without clear contemporaneous records.

8. Should I accelerate equipment purchases into 2026 to capture bonus depreciation?

If you have planned equipment purchases, accelerating them into 2026 to capture 100% bonus depreciation deductions makes economic sense. However, ensure the equipment is actually placed in service (installed and operational) before December 31, 2026. Additionally, consider whether cash flow supports the investment and whether you have sufficient taxable income in 2026 to benefit from the deductions. Consult with tax professionals to model the financial impact before committing to accelerated purchases.

9. What should Michigan business owners do if they received outdated tax guidance earlier in 2026?

The IRS updated guidance on qualified tips deductions and other provisions in early 2026, after many taxpayers and preparers filed 2025 returns using earlier interpretations. If you filed using earlier guidance that conflicts with updated IRS guidance, consult with your tax professional about whether amended returns are necessary. The IRS generally waives penalties for good-faith reliance on official guidance, but amended returns may still be prudent to ensure compliance and maximize deductions.
