What Is the Maximum Amount I Can Earn and Still Claim the Qualified Business Income Deduction (QBID)?

The Qualified Business Income Deduction (QBID), also known as the 20% small business deduction, is available to many self-employed individuals, independent contractors, and small business owners.

For tax year 2026 (returns filed in 2027), eligibility and limitations depend on both your taxable income and the type of business you operate.

The program automatically calculates your QBID based on the business income entered on your return.

Income Thresholds for 2026

For many taxpayers, the full deduction is available when taxable income is at or below the following thresholds:
  • Single filers: $197,300
  • Married Filing Jointly: $394,600

If your taxable income exceeds these amounts, additional limitations may apply.

For businesses that are not classified as specified service trades or businesses (SSTBs), the deduction may become limited based on factors such as:

  • Wages paid to employees
  • The business's qualified property
  • Qualified business income
As income increases above the threshold amounts, the IRS applies additional calculations to determine the allowable deduction.

What If I Own a Specified Service Trade or Business (SSTB)?

Special rules apply if your business is considered a Specified Service Trade or Business (SSTB).

For 2026, the deduction begins to phase out when taxable income exceeds:

  • Single filers: $197,300
  • Married Filing Jointly: $394,600
The deduction is completely phased out once taxable income reaches:
  • Single filers: $247,300
  • Married Filing Jointly: $494,600
If your income falls within the phaseout range, you may qualify for a partial deduction. If your income exceeds the upper limit of the phaseout range, no QBID is allowed for income from an SSTB.

What Is a Specified Service Trade or Business?

The IRS generally defines a Specified Service Trade or Business as a business where the principal asset is the reputation or skill of its owners or employees. Common examples include businesses in the fields of:
  • Health
  • Law
  • Accounting
  • Actuarial science
  • Performing arts
  • Consulting
  • Athletics
  • Financial services
  • Investing
  • Investment management
Other professions may also be classified as SSTBs under IRS rules depending on the nature of the services provided.

How Is the Deduction Calculated?

The QBID is generally based on 20% of your qualified business income, but the actual deduction can be affected by:
  • Your taxable income
  • The type of business you operate
  • Employee wages paid by the business
  • Qualified business property
  • Whether the business is an SSTB
Because the calculation can become complex at higher income levels, the deduction you receive may be less than 20% of your business income.

Do I Need to Calculate the Deduction Myself?

The program automatically calculates the Qualified Business Income Deduction using the information entered on your return.

To help ensure the calculation is accurate:

  • Enter all business income.
  • Enter all business expenses.
  • Complete any applicable Schedule C, partnership, or S corporation entries.
  • Review your return after completion.
