If you’re a small-business owner approaching retirement, 2026 brings notable tax changes that could impact your planning strategy. Between the enhanced senior deduction, Social Security benefit rules that can affect your taxes, and recent legislative shifts, there’s much to consider when mapping out your exit from active business ownership.

Here’s what you need to know about how these changes work together and how they might affect your retirement income.

Understanding the Enhanced Senior Deduction for 2026

Starting in 2026 and running through 2028, seniors aged 65 and older can claim an enhanced deduction on top of their standard deduction. This provision allows up to $6,000 per individual or $12,000 for joint filers to be deducted from taxable income.

However, this deduction isn’t available to everyone. It phases out based on your modified adjusted gross income (MAGI). For single filers, the phase-out starts at $75,000 and completes at $175,000. For married couples filing jointly, it begins at $150,000 and ends at $250,000.

What makes this particularly interesting for business owners is that this deduction stacks with both the standard deduction and the additional age-based deduction ($2,050 for single filers, $1,650 per spouse for joint filers in 2026). When you add these together, a single senior could potentially have up to $24,150 in tax-free income in 2026, while a married couple filing jointly could reach $47,500.

For a sole proprietor or S-Corp owner winding down operations, this enhanced deduction could meaningfully reduce taxable income from business earnings or Social Security benefits. Timing matters. You’ll want to consider how your business income affects your MAGI and whether strategic timing of income recognition could help you stay within the phase-out ranges.

How Social Security Benefits Get Taxed for Business Owners

Social Security taxation works differently than many expect, and understanding these thresholds becomes especially important when you’re still receiving business income.

Your Social Security benefits start becoming taxable based on what’s called combined income which includes your adjusted gross income, nontaxable interest, and half of your Social Security benefits.

Here’s how the taxation typically breaks down:

  • 50% of benefits become taxable when combined income reaches $25,000 to $34,000 for single filers, or $32,000 to $44,000 for joint filers

  • 85% of benefits become taxable above those thresholds

Hypothetically, if you’re a 67-year-old sole proprietor with $40,000 in net business earnings and $20,000 in Social Security benefits, a significant portion of those benefits would likely face ordinary income taxes. The enhanced senior deduction could help reduce that tax burden by lowering your overall taxable income.

Self-Employment Taxes and Social Security Rules for 2026

Small-business owners face a different tax situation than traditional employees when it comes to Social Security. As a self-employed individual, you’re generally responsible for the full 15.3% self-employment tax on net earnings:

  • 12.4% goes to Social Security (capped at the wage base, which is $184,500 for 2026)

  • 2.9% goes to Medicare (no cap)

  • An additional 0.9% Medicare surtax applies to income above $200,000 for single filers or $250,000 for joint filers

One strategy many business owners explore is the S-Corporation election. With an S-Corp structure, you generally pay self-employment taxes only on your reasonable salary—not on distributions. This approach can potentially reduce your overall self-employment tax burden, though you’ll want to work with a tax professional to determine what constitutes a reasonable salary for your role.

You can also deduct half of your self-employment tax as an above-the-line deduction, which reduces your adjusted gross income.

The Social Security Fairness Act: What Changed

The Social Security Fairness Act repealed two provisions that previously reduced benefits for certain retirees:

This repeal could increase benefits for small-business owners who also worked in public-sector positions or have spouses with government pensions. If this applies to your situation, you may see higher Social Security payments than you originally anticipated.

Maximizing Retirement Contributions as a Business Owner

One of the most effective ways to reduce taxable income while building retirement savings is through tax-deferred retirement contributions. The limits for 2026 are particularly generous for self-employed individuals.

Solo 401k Plans

The Solo 401k offers the highest contribution potential for self-employed business owners. In 2026, you can make:

  • Up to $24,500 in employee deferrals (or $32,500 if you’re age 50 or older)

  • Plus employer contributions up to 25% of compensation

  • Combined annual maximum of $72,000 (or $83,250 if you’re between age 60–63 years old, thanks to enhanced catch-up provisions)

Hypothetically, if you’re 62 with $200,000 in net self-employment earnings, you could potentially contribute the full $83,250 to a Solo 401k, significantly reducing your taxable income.

You can also contribute to a Roth Solo 401k. In 2026, you can contribute up to $24,500 to a Roth Solo 401k ($32,500 if age 50 or older).

SEP IRA

A SEP IRA allows contributions up to 25% of net self-employment earnings, with a maximum of $72,000 for 2026. This option works well if you prefer simplicity and don’t need the employee deferral component.

One important differentiator: SEP IRAs don’t offer catch-up contributions or Roth options, which may matter depending on your age and tax strategy.

SIMPLE IRA

For smaller operations, a SIMPLE IRA allows employee deferrals of up to $18,100 in 2026, plus employer matching or non-elective contributions. If you’re 50 or older, you can add catch-up contributions.

Note: The amount of income required to max out these contributions can vary, but the key terms are net income, net adjusted income, and gross income after accounting for self-employment deductions.

The Qualified Business Income Deduction: 20%

The Section 199A Qualified Business Income (QBI) deduction remains one of the most valuable tax breaks for pass-through entities like sole proprietorships, partnerships, LLCs, and S-Corporations.

This deduction generally allows you to deduct up to 20% of qualified business income from your taxable income. The deduction is subject to limitations that phase in over a taxable-income range, and for 2026 the phase-in range is $75,000 for single filers and $150,000 for joint filers.

This change could meaningfully affect after-tax business income, potentially freeing up more cash to fund retirement accounts or other savings vehicles.

Accelerated Depreciation Under OBBBA

The OBBBA also restored permanent 100% bonus depreciation for eligible property acquired after January 19, 2025, and raised the Section 179 deduction limit to $2.5 million.

These provisions allow you to immediately deduct the full cost of qualifying business assets rather than depreciating them over several years. For business owners approaching retirement, this could accelerate deductions and free up cash flow—though you’ll want to consider how these larger deductions interact with the senior deduction phase-out thresholds.

Additional Tax-Saving Strategies for Business Owners

Self-Employed Health Insurance Deduction

If you’re self-employed and pay for your own health insurance, you can typically deduct 100% of premiums as an above-the-line deduction. This reduces your adjusted gross income, which helps with both ordinary income taxes and the senior deduction phase-out calculations.

Health Savings Accounts (HSAs)

If you have a high-deductible health plan, an HSA offers triple tax benefits: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses aren’t taxed.

For 2026, contribution limits are:

  • $4,400 for individual coverage

  • $8,750 for family coverage

  • Plus an additional $1,000 catch-up contribution if you’re 55 or older

HSAs work particularly well in retirement planning because after age 65 you can withdraw funds for any purpose (though non-medical withdrawals face ordinary income taxes, similar to a traditional IRA).

Coordinating Business Income with the Senior Deduction

The enhanced senior deduction creates planning opportunities and challenges for business owners.

Since the deduction phases out based on MAGI, explore strategies that keep your income within the beneficial ranges. This might include:

  • Timing income recognition by deferring invoices or accelerating deductible expenses

  • Maximizing retirement contributions to reduce adjusted gross income

  • Exploring S-Corp distributions instead of salary (while maintaining reasonable compensation)

  • Considering asset depreciation timing to manage taxable income year-to-year

Hypothetically, if you’re a single filer with $85,000 in business income, making a $20,000 401k contribution and deducting $8,000 in self-employed health insurance could potentially bring your MAGI down to $57,000 (after the self-employment tax deduction). This would keep you well within the range to claim the full $6,000 senior deduction.

Planning Your Retirement Transition

For small-business owners, retirement planning isn’t just about saving money. It’s about strategically transitioning out of active business ownership while minimizing tax liability.

Consider these timing factors:

Before Age 65: Focus on maximizing retirement contributions and potentially accelerating income if you expect to be in a lower bracket later.

Ages 65–72: Take advantage of the enhanced senior deduction while managing income to stay within phase-out ranges. This could be an ideal time to convert traditional retirement accounts to Roth accounts if your income is temporarily lower.

After Age 73 (when required minimum distributions begin): Your retirement account withdrawals become mandatory, which could push you above the senior deduction thresholds. Plan ahead for this transition.

Entity Structure Considerations

Your business structure significantly affects how these provisions apply:

Sole Proprietorship: You’ll pay self-employment tax on all net earnings. The enhanced senior deduction and QBI deduction apply directly to your individual return.

S-Corporation: You can potentially minimize self-employment taxes by taking a reasonable salary and receiving the rest as distributions. The QBI deduction generally applies to your share of business income.

Partnership or Multi-Member LLC: Your share of partnership income flows through to your individual return, where the QBI deduction and senior deduction typically apply.

Each structure has different implications for retirement contributions, self-employment taxes, and how the various deductions interact.

What These Changes Mean for Your 2026 Planning

Here’s a summary of how these provisions work together:

Enhanced Senior Deduction: Up to $6,000 per eligible individual in 2026 (phases out above $75,000 single and $150,000 joint; fully phases out at $175,000 single and $250,000 joint) and is available through 2028.

QBI Deduction: Generally up to 20% of qualified business income; for 2026 the law expands the phase-in range to $75,000 single and $150,000 joint and adds a $400 minimum deduction rule for certain taxpayers.

Social Security Wage Base: $184,500 for 2026, which caps the Social Security portion of self-employment tax.

Solo 401k: $72,000 maximum for 2026 ($83,250 with enhanced catch-up for age 60–63, if available under the plan).

Bonus Depreciation: Permanent 100% bonus depreciation for eligible property acquired after January 19, 2025.

Steps to Take Now

If you’re a small-business owner planning retirement over the next few years, consider these actions:

  • Review your current entity structure to determine if an S-Corp election or other change might reduce self-employment taxes.

  • Calculate your projected MAGI for 2026 to see if you’ll qualify for the enhanced senior deduction and explore strategies to stay within the phase-out ranges.

  • Maximize retirement contributions based on your business income and entity type. The Solo 401k generally offers the highest contribution limits for self-employed individuals.

  • Explore the timing of major business expenses or asset purchases to take advantage of 100% bonus depreciation and Section 179 deductions.

  • Consider how Social Security benefits will be taxed alongside your business income and whether delaying benefits might make sense in your situation.

  • Work with a tax professional who understands small-business taxation and retirement planning. The interaction between these provisions can get complex, and personalized guidance can help you avoid costly mistakes.

Looking Ahead

The combination of the enhanced senior deduction, updated QBI rules, and restored bonus depreciation creates meaningful opportunities for small-business owners approaching retirement. These provisions could reduce your tax burden while you’re still generating business income and help you transition more smoothly into full retirement.

However, the phase-out thresholds and interaction between different tax provisions require careful planning. What works for one business owner may not work for another, depending on income levels, business structure, and retirement goals.

The key is to start planning now rather than waiting until you’re ready to retire. Small adjustments to how you structure income, time deductions, and fund retirement accounts could save meaningful dollars in ordinary income taxes over the next several years.
