Self-employed individuals can determine their eligibility for the qualified business income (QBI) deduction by following a series of steps that analyze the nature of their business, the type and amount of income, and their overall taxable income. The QBI deduction, under IRC §199A, allows eligible taxpayers to deduct up to 20% of their qualified business income, subject to several limitations and requirements. Here’s a comprehensive guide to determining QBI eligibility for self-employed individuals, with references to the Internal Revenue Code, Treasury Regulations, and IRS guidance:

1. Confirm the Business Structure and Type

  • Eligible Entities: The QBI deduction is available to individuals with income from a qualified trade or business operated as a sole proprietorship, partnership, S corporation, trust, or estate. C corporations are not eligible.
  • Self-Employed Individuals: Sole proprietors report business income on Schedule C (Form 1040) and are eligible to claim the deduction if other requirements are met.

2. Determine if the Activity is a Qualified Trade or Business

  • Section 162 Standard: The activity must rise to the level of a trade or business under IRC §162, meaning it is conducted with continuity and regularity and with a primary purpose of income or profit.
  • Rental Real Estate: Rental real estate may qualify if it meets the section 162 standard or the IRS safe harbor for rental real estate enterprises.

3. Exclude Ineligible Businesses

  • C Corporations: Income earned through a C corporation is not eligible.
  • Employee Services: Income earned as an employee is not eligible.
  • Specified Service Trade or Business (SSTB): If the business is an SSTB (e.g., health, law, accounting, consulting, athletics, financial services, or where the principal asset is the reputation or skill of one or more employees/owners), eligibility may be limited or phased out at higher income levels.

4. Calculate Qualified Business Income (QBI)

  • Definition: QBI is the net amount of qualified items of income, gain, deduction, and loss from any qualified trade or business, effectively connected with the conduct of a trade or business within the United States.
  • Inclusions: Ordinary business income, minus deductions such as the deductible part of self-employment tax, self-employed health insurance, and retirement plan contributions.
  • Exclusions: QBI does not include:
  • Capital gains or losses
  • Dividends
  • Interest income not allocable to the business
  • Wage income
  • Guaranteed payments to partners
  • Reasonable compensation paid to S corporation shareholders
  • Certain other investment items.

5. Determine Taxable Income and Apply Thresholds

  • Thresholds for 2025: For 2025, the QBI deduction thresholds are:
  • $394,600 for married filing jointly
  • $197,300 for single, head of household, or married filing separately.
  • Taxable Income Calculation: Taxable income is calculated before the QBI deduction and without regard to net capital gain.

6. Apply Limitations Based on Taxable Income

  • Below Threshold: If taxable income is at or below the threshold, the deduction is generally 20% of QBI, regardless of whether the business is an SSTB or not.
  • Within Phase-In Range: If taxable income is within the phase-in range (up to $100,000 above the threshold for joint filers, $50,000 for others in 2025), the deduction may be limited by:
  • The type of business (SSTB phase-out)
  • The W-2 wage and qualified property limitation (phased in over the range).
  • Above Phase-In Range: If taxable income exceeds the phase-in range:
  • For SSTBs, no deduction is allowed.
  • For non-SSTBs, the deduction is limited to the greater of:
    • 50% of W-2 wages paid by the business, or
    • 25% of W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property.

7. Special Rules and Additional Considerations

  • Aggregation: Taxpayers may aggregate multiple trades or businesses if certain requirements are met, which can affect the calculation of QBI, W-2 wages, and UBIA.
  • Losses: If the net QBI is negative, the loss is carried forward to offset QBI in future years.
  • Cooperatives: Special rules apply for patrons of agricultural or horticultural cooperatives.

8. Calculate the Deduction

  • General Rule: The deduction is the lesser of:
  • 20% of QBI, or
  • 20% of taxable income (before the QBI deduction and net capital gain).

9. File the Appropriate Form

  • Form 8995: Use if taxable income is at or below the threshold and not a patron of a specified cooperative.
  • Form 8995-A: Use if taxable income exceeds the threshold or if a patron of a specified cooperative.

10. Summary of Steps for Self-Employed Individuals

  1. Confirm your business is a qualified trade or business (not a C corporation or employee activity).
  2. Calculate your QBI by subtracting allowable deductions from your business income.
  3. Determine your taxable income before the QBI deduction.
  4. Check if your business is an SSTB and whether your taxable income is above, within, or below the threshold/phase-in range.
  5. Apply the appropriate limitations (SSTB exclusion, W-2 wage/UBIA limits) based on your taxable income.
  6. Calculate the deduction as the lesser of 20% of QBI or 20% of taxable income (before QBI deduction and net capital gain).
  7. File Form 8995 or 8995-A as appropriate.

In summary: Self-employed individuals are eligible for the QBI deduction if they have income from a qualified trade or business (other than a C corporation or employee services), their QBI is properly calculated, and their taxable income is within the applicable thresholds. The deduction is subject to limitations based on taxable income, the type of business (SSTB or not), and the amount of W-2 wages and qualified property. Proper calculation and reporting on the correct IRS form are essential for claiming the deduction.
