The Small Business Owner's Guide to the OBBBA in 2026: Are You Leaving Money on the Table?

If you own a small business, 2026 is the first full year you can plan around several major OBBBA provisions instead of treating them as temporary possibilities. The One Big Beautiful Bill Act (OBBBA) made the 20% qualified business income deduction permanent, restored 100% bonus depreciation, and expanded Section 179 expensing.

That doesn’t mean every business should immediately buy equipment or change its entity structure. It means you now have more planning options, and you’ll want to use them deliberately.

Here’s what you should actually do in 2026.

1. Confirm Whether Your Business Can Benefit From the Permanent QBI Deduction

The qualified business income (QBI) deduction generally allows eligible owners of pass-through businesses to deduct up to 20% of qualified business income. It may apply to:

  • Sole proprietorships
  • Partnerships
  • LLCs taxed as partnerships
  • S corporations
  • Certain trusts and estates

The deduction generally DOES NOT apply directly to income earned through a traditional C corporation.

Before OBBBA, many owners were concerned that the QBI deduction would expire after 2025. OBBBA removed that sunset, making the deduction permanent under current law.

However, “permanent” doesn’t mean “automatic.” Your deduction can still be affected by:

  • Your taxable income
  • Whether your business is a specified service trade or business (SSTB)
  • W-2 wages paid by the business
  • The basis of qualified business property
  • Your taxable income less net capital gain

For example, an owner of a construction company may have different QBI limitations than an owner of a consulting practice. A high-income professional in a specified service business may see the deduction reduced or eliminated, depending on income and other factors.

What you should do now:

  1. Ask us to project your 2026 taxable income.
  2. Review whether your business is an SSTB.
  3. Confirm that payroll records accurately reflect W-2 wages.
  4. Review fixed-asset records and qualified property basis.
  5. Compare your expected QBI deduction with your estimated federal tax liability.

You can review the IRS’s general explanation of the deduction through its qualified business income deduction guidance.

2. Check the New $400 Minimum QBI Deduction

Beginning with the 2026 tax year, OBBBA adds a new minimum deduction for certain active business owners.

If you have at least $1,000 of net QBI from one or more active businesses in which you materially participate, you may qualify for a minimum QBI deduction of $400 (subject to the applicable rules).

This is especially important for owners of smaller businesses whose regular 20% calculation might otherwise produce a very small deduction. The minimum applies to qualifying active business income, not simply passive investment income.

Material participation generally means you’re meaningfully involved in the business’s operations. You should maintain records that support your involvement, such as:

  • Time spent managing the business
  • Customer and vendor communications
  • Operational decisions
  • Employee supervision
  • Business travel
  • Scheduling and administrative work

Your records don’t have to be complicated, but they should be consistent and credible.

Action item: If your business generated at least $1,000 of QBI and you actively participated during 2026, ask us to review whether the minimum deduction applies to you.

3. Use 100% Bonus Depreciation Carefully, Not Automatically

OBBBA permanently restored 100% bonus depreciation for qualifying property under the applicable acquisition and placed-in-service rules. In practical terms, eligible businesses may be able to deduct the full cost of qualifying property in the first year instead of depreciating it over several years.

Potentially qualifying assets may include:

  • Machinery and equipment
  • Computers and technology
  • Furniture and fixtures
  • Certain vehicles
  • Other eligible tangible business property

The key phrase is “placed in service.” Signing a purchase agreement or leaving equipment in a warehouse may not be enough. The asset generally must be ready and available for business use under the applicable tax rules.

Why immediate expensing can help

Suppose your company purchases $80,000 of qualifying equipment and places it in service during 2026. Depending on the facts, 100% bonus depreciation could create a substantial first-year deduction.

That deduction may:

  • Reduce current taxable income
  • Improve near-term cash flow
  • Help offset income from a profitable year
  • Support a planned expansion

But there’s an important tradeoff: depreciation reduces QBI. A large first-year deduction may reduce the income used to calculate your QBI deduction.

That means the biggest first-year write-off isn’t always the best overall strategy. You may want to compare:

  • Taking 100% bonus depreciation now
  • Using regular depreciation over several years
  • Combining bonus depreciation with Section 179
  • Purchasing or placing the asset in service during a different tax year

DO NOT buy equipment solely to create a tax deduction. A deduction reduces taxable income; it doesn’t make an unprofitable purchase profitable.

Before purchasing a major asset, send us:

  • The purchase price
  • The expected purchase date
  • The expected in-service date
  • The business-use percentage
  • The estimated financing terms
  • The expected business benefit

We’ll help you evaluate both the tax result and the cash-flow impact.

4. Compare Bonus Depreciation With Section 179

Section 179 remains another valuable tool for small businesses. OBBBA increased the Section 179 limit, with the 2026 limit reported at $2,560,000 before the applicable phase-out rules.

Section 179 may give you more flexibility because you can often choose which qualifying assets to expense. Bonus depreciation, by contrast, generally applies according to the property and election rules.

Your decision may depend on:

  • The cost of the asset
  • Total equipment purchases
  • Your taxable income
  • Whether the business has a current-year loss
  • State tax treatment
  • The effect on QBI
  • Whether you want to preserve deductions for future years

For example, you might use Section 179 for selected equipment while using regular depreciation for another asset. In other cases, 100% bonus depreciation may provide a more efficient result.

Action item: Don’t let your bookkeeping software make this decision automatically. Have your tax professional compare both options before your final year-end depreciation entries are posted.

5. Review Payroll, Retirement Contributions, and Owner Compensation

Tax planning isn’t limited to deductions. Your payroll and retirement strategy can also affect your overall tax picture.

If you operate an S corporation, review whether your owner compensation is reasonable and properly documented. Paying too little salary can create payroll tax and compliance concerns. Paying too much may reduce potential QBI without providing a corresponding benefit.

You should also review retirement plan contributions. The 2026 limits include:

  • 401(k) elective deferrals: $24,500
  • Standard age-50-and-over catch-up: $8,000
  • Enhanced age 60–63 catch-up: $11,250, where applicable
  • Defined contribution plan annual additions: $72,000
  • SEP contribution maximum: generally limited to the lesser of applicable compensation percentages or $72,000
  • SIMPLE plan deferrals: $17,000, subject to applicable rules

Your plan type, compensation, age, employee participation, and business structure all matter.

Action item: Review retirement contributions before year-end, not after the tax return is prepared. Visit our retirement planning page to learn more about planning options.

6. Improve Documentation Before Tax Season

The OBBBA may create additional planning opportunities, but weak records can prevent you from claiming deductions confidently.

Review your records for:

  • Business mileage and vehicle use
  • Equipment invoices and placed-in-service dates
  • Business travel receipts
  • Cell phone and internet expenses
  • Contractor payments and Forms 1099
  • Payroll records
  • Retirement contributions
  • Loan interest
  • Inventory and supplies

Some expenses require extra care. For example, a business trip may include deductible transportation and lodging, but personal sightseeing generally isn’t deductible. A cell phone may be partially deductible based on business use. Country club dues are generally NOT deductible, even if you meet clients there.

Keep business and personal spending separate whenever possible. Upload receipts regularly and add a short business purpose to unusual expenses.
