Practical Tax-Saving Strategies for Small Business Owners in 2026

Practical tax-saving strategies for individuals, freelancers, and small-business owners under the latest federal tax laws.

As 2026 draws to a close, now is the time to review your finances and identify opportunities to reduce your tax burden before the year ends. Thoughtful year-end tax planning can help you keep more of your hard-earned money, avoid unnecessary penalties, and prepare for a smoother tax filing season.

The federal tax law enacted in July 2025, commonly known as the One Big Beautiful Bill Act (OBBBA), introduced several significant changes affecting the 2026 tax year. These include expanded business deductions, new tax benefits for certain workers, and changes to charitable giving and retirement planning.

The key is to act before important deadlines pass. Here are 10 practical tax-planning strategies to consider before December 31, 2026.

1. Review Your Income and Tax Bracket

Effective tax planning begins with understanding your expected annual income. Review your wages, self-employment earnings, business profits, investment gains, interest, dividends, and other taxable income.

For 2026, the federal standard deduction amounts are:

These amounts are higher than in 2025, potentially reducing taxable income for many households. Understanding your projected tax bracket can also help you evaluate whether to accelerate deductible expenses, defer certain income, or make additional retirement contributions.

Tax planning tip: Moving into a higher tax bracket does not mean all your income is taxed at that higher rate. Under the progressive federal income-tax system, only the portion of taxable income falling within a particular bracket is taxed at that bracket's rate.

2. Maximize Your Retirement Contributions

Contributing to tax-advantaged retirement accounts is one of the most effective ways to prepare for retirement while potentially reducing current taxable income. The IRS has increased several retirement contribution limits for 2026.

2026 Retirement Contribution Limits

For example, an eligible employee age 55 may contribute up to $32,500 to a traditional 401(k) in 2026, including catch-up contributions, if the plan permits. An eligible employee between ages 60 and 63 may contribute up to $35,750. Certain SIMPLE plans have higher contribution limits, and employer contributions are governed by separate rules.

Important 2026 change: Under SECURE 2.0, certain higher-income employees with more than $150,000 in prior-year wages from their plan sponsor must make eligible catch-up contributions on a Roth basis, subject to the applicable rules. Traditional pre-tax retirement contributions can reduce current taxable income. Roth contributions generally do not provide an immediate income-tax deduction but may offer tax-free qualified withdrawals in retirement.

IRA deductibility and Roth IRA eligibility are subject to income and other restrictions.

Year-end action: Review your retirement contributions before your final payroll of 2026. Eligible IRA contributions for 2026 can generally be made until April 15, 2027.

3. Consider Tax-Loss Harvesting

If you own stocks, mutual funds, or exchange-traded funds in a taxable brokerage account, review your realized investment gains and losses before December 31. Tax-loss harvesting involves selling investments that have declined in value to realize losses that may offset taxable capital gains.

For example, suppose you realized $8,000 in capital gains during 2026 and have another investment showing a $5,000 unrealized loss. Selling that investment before year-end could potentially reduce your net taxable capital gains to $3,000, assuming the applicable rules are satisfied. If total capital losses exceed capital gains, individuals can generally deduct up to $3,000 of the remaining net capital loss against ordinary income annually ($1,500 for married taxpayers filing separately). Unused capital losses may generally be carried forward.

Watch Out for the Wash-Sale Rule

The IRS wash-sale rule can disallow an immediate loss deduction if you purchase substantially identical securities within 30 days before or after selling an investment at a loss. This rule can also affect transactions involving certain retirement accounts.

Tax planning tip: Never make an investment decision solely for a tax deduction. Consider your overall investment strategy, transaction costs, and long-term financial goals.

4. Take Advantage of Health Savings Accounts

A Health Savings Account (HSA) can be a valuable tax-planning tool for individuals with qualifying health coverage. HSAs offer three major federal tax advantages:

• Eligible contributions are deductible or excluded from taxable income.

• Investment growth within the account is generally tax-free.

• Withdrawals used for qualified medical expenses are tax-free.

  
  

2026 HSA Contribution Limits

These limits generally include both employee and employer contributions and may be prorated based on eligibility.

New HSA Eligibility Rules for 2026

Beginning in 2026, certain Bronze and Catastrophic health insurance plans qualify for expanded HSA treatment under the new federal law. Certain direct primary care arrangements also receive favorable treatment. However, eligibility still depends on other factors, including disqualifying coverage and Medicare enrollment.

Year-end action: Verify whether your health insurance qualifies for HSA contributions. Eligible contributions for tax year 2026 can generally be made until April 15, 2027.

5. Review Business Equipment Purchases and Depreciation

Small-business owners may be able to reduce taxable business income by deducting the cost of qualifying equipment and other business assets. Recent federal legislation expanded Section 179 expensing and restored 100% bonus depreciation for qualifying property acquired and placed in service under the applicable rules.

Qualifying assets may include computers, machinery, office furniture, equipment, and certain business improvements.

Section 179 Versus Bonus Depreciation

Section 179 generally allows eligible businesses to elect an immediate deduction for qualifying property, subject to annual dollar limits, investment thresholds, taxable-income limitations, and other requirements. Bonus depreciation may permit an additional first-year deduction for qualifying property and operates under different rules.

The two provisions are not interchangeable, and not every purchase qualifies. For an eligible asset, the potential tax benefit can be substantial.

Example: A business purchasing $10,000 of qualifying equipment may be able to deduct the full eligible cost in the year the equipment is placed in service. If the deduction reduces taxable income subject to a 24% marginal federal income-tax rate, the illustrative income-tax savings could be $2,400. However, the business still spends $10,000 to purchase the equipment.

Tax planning tip: Purchase equipment because it supports your business, not simply to generate a deduction. Also, remember that an asset generally must be placed in service, not merely ordered, to qualify for depreciation in that tax year.

6. Review the Qualified Business Income Deduction

The Qualified Business Income (QBI) deduction, also known as the Section 199A deduction, can provide significant tax savings to eligible small-business owners. Certain sole proprietors, partnerships, S corporation shareholders, and other eligible taxpayers may qualify for a deduction of up to 20% of qualified business income. The 2025 federal tax legislation made the QBI deduction permanent.

New $400 Minimum QBI Deduction

Beginning in 2026, eligible taxpayers with at least $1,000 of qualified business income from qualifying active businesses in which they materially participate may be entitled to a minimum QBI deduction of $400, subject to applicable requirements. The actual deduction depends on factors such as taxable income, business activities, wages, qualified property, and other limitations.

Not every LLC automatically qualifies, and wages earned as an employee are not considered qualified business income.

Year-end action: If you're self-employed or operate a pass-through business, review your projected net profit and business expenses to estimate whether you qualify for the QBI deduction.

7. Make Charitable Contributions Strategically

Charitable contributions may provide tax benefits while supporting organizations and causes that matter to you. Beginning in 2026, taxpayers who claim the standard deduction may also qualify for a new federal deduction for eligible cash charitable contributions.

New Charitable Deduction for Non-Itemizers

These deductions apply to qualifying cash contributions to eligible organizations and are subject to additional restrictions. For taxpayers who itemize, new rules generally limit deductible charitable contributions to amounts exceeding 0.5% of adjusted gross income, along with other applicable limitations.

Consider Donating Appreciated Investments

Taxpayers who itemize may benefit from donating appreciated stocks or other eligible investments held for more than one year. In appropriate circumstances, this can allow a deduction based on fair market value while avoiding recognition of the appreciation as a capital gain. However, the rules vary depending on the donated property, recipient organization, holding period, and applicable deduction limits.

Year-end action: Make qualifying donations by December 31, 2026, and retain the required receipts and acknowledgments.

8. Check Whether You Qualify for New Federal Tax Deductions

Several new federal income-tax deductions introduced under the 2025 legislation may benefit eligible taxpayers in 2026.

Qualified Overtime Compensation

Eligible workers may deduct certain qualified overtime compensation, subject to annual limits and income phaseouts. The deduction generally applies to the qualifying overtime premium required under federal law, rather than the entire amount of overtime wages.

Qualified Tips

Workers in eligible occupations may deduct qualifying tip income, subject to specific reporting rules, dollar limits, and income restrictions.

Interest on Qualifying New Vehicle Loans

Eligible taxpayers may deduct up to $10,000 of annual interest paid on qualifying loans for certain new vehicles, subject to income limits and vehicle requirements. Not every vehicle or automobile loan qualifies.

Additional Deduction for Eligible Seniors

Taxpayers age 65 or older may qualify for an additional deduction of up to $6,000 per eligible individual, subject to income limitations. For eligible married couples filing jointly, the combined additional deduction may reach $12,000.

Important: These benefits are deductions from federal taxable income, not blanket exemptions from all taxes. Some have specific documentation requirements, and certain benefits are temporary rather than permanent.

9. Review Your Tax Withholding and Estimated Payments

Unexpected tax bills often result from insufficient withholding or missed estimated tax payments. Review your withholding if you experienced significant changes during 2026, including:

• Starting or changing jobs.

• Receiving bonuses or additional compensation.

• Earning freelance or self-employment income.

• Realizing substantial investment gains.

• Experiencing changes in marital or dependent status.

  
  

Employees can review their Form W-4 and use the IRS Tax Withholding Estimator. Self-employed individuals and others with income not subject to withholding may need to make quarterly estimated tax payments.

The fourth federal estimated tax payment for calendar-year 2026 is generally due January 15, 2027, although special rules and exceptions may apply.

Tax planning tip: Making an estimated payment does not necessarily eliminate penalties from earlier periods of underpayment. Review your payments throughout the year rather than waiting until tax filing season.

10. Get Your Small-Business Books Tax-Ready

For small-business owners, organized bookkeeping is one of the most important foundations of effective tax planning. Accurate records make it easier to identify deductible expenses, evaluate business profitability, manage cash flow, and prepare financial statements. Before December 31, review the following:

Year-End Bookkeeping Checklist

• Reconcile all business bank and credit card accounts.

• Review outstanding customer invoices and unpaid bills.

• Categorize business expenses accurately.

• Separate personal and business transactions.

• Review fixed assets and equipment purchases.

• Confirm payroll records and employee information.

• Review contractor payments and Form 1099 reporting requirements.

• Verify inventory records, if applicable.

• Review owner contributions, draws, and distributions.

• Prepare a year-to-date Profit and Loss Statement and Balance Sheet.

  
  

Business owners should also consider whether their accounting method affects the timing of income and expense recognition. For example, cash-basis and accrual-basis businesses may have different tax results when invoices are issued or bills are paid near year-end.

Tax planning tip: A profitable business can still experience cash flow problems. Reviewing your financial statements regularly helps you understand both profitability and liquidity.

Important Tax Planning Deadlines

Some opportunities must be completed before December 31, while others remain available into 2027.

Certain business retirement plans and other tax elections have different deadlines. Consult a qualified tax professional to determine which deadlines apply to your circumstances.

A Note for New York Business Owners and Taxpayers

Federal tax deductions do not always receive identical treatment under New York State or New York City tax laws. For example, certain federal deductions, depreciation provisions, and other tax benefits may require different calculations or adjustments on state and local returns. Business owners operating in New York should consider federal, state, and local tax implications together when making year-end financial decisions.

Final Thoughts: Good Tax Planning Starts Before Tax Season

Effective tax planning is not about finding last-minute loopholes. It is about understanding the rules, maintaining accurate records, and making informed financial decisions throughout the year. The final months of 2026 provide an opportunity to review retirement contributions, investments, business expenses, charitable giving, and estimated tax payments. Even small adjustments can make a meaningful difference when they are part of a thoughtful financial plan.

Most importantly, remember that a tax deduction should support a sound financial decision—not drive an unnecessary expense.
