Qualified Income Deduction Phaseout: 2025 Limits

The qualified business income (QBI) deduction does not have one universal phaseout: for 2025, the deduction’s wage-and-property limits begin to apply above taxable income of $197,300 for most filers, or $394,600 for joint filers. For specified service trades or businesses (SSTBs), the deduction phases out over the next $50,000 of taxable income, or $100,000 for joint filers, and is generally unavailable above that range.

What the QBI deduction is

The QBI deduction, also called the Section 199A deduction, may allow eligible taxpayers to deduct up to 20% of qualified business income from certain pass-through businesses. Eligible income can come from sole proprietorships, partnerships, S corporations, and some trusts or estates. It is claimed by individuals and certain other noncorporate taxpayers; it is not a deduction claimed by a C corporation on its corporate return.

The deduction is generally limited to the lesser of the combined QBI amount and 20% of taxable income minus net capital gain. The taxable-income ceiling means that even a taxpayer with substantial qualified business income may not deduct more than 20% of taxable income after subtracting net capital gain. The calculation has additional rules, so the headline “20% deduction” is not a guarantee that every owner receives a deduction equal to one-fifth of business profit.

2025 income thresholds and phaseout

The relevant income test uses taxable income before the QBI deduction, not gross income, business revenue, or adjusted gross income. For 2025, the threshold is $197,300 for an individual, head of household, or other non-joint return, and $394,600 for a married couple filing jointly. The phase-in range is $50,000 for non-joint filers and $100,000 for joint filers.

• At or below the threshold: The wage-and-property limitation generally does not restrict the QBI component. SSTB income may qualify, subject to the other requirements and overall taxable-income limit.
• Within the phase-in range: The wage-and-property limitation is gradually applied. For an SSTB, the amount of income eligible for the deduction is also gradually reduced.
• Above the range: An SSTB generally cannot generate a QBI deduction. For a non-SSTB, the wage-and-property limitation applies in full, but a deduction may remain available.

For example, a single filer with 2025 taxable income of $220,000 is $22,700 above the $197,300 threshold and remains within the $50,000 phase-in range. That does not by itself reveal the deduction: the business’s QBI, W-2 wages, qualified property, SSTB status, and the taxpayer’s net capital gain and taxable income also matter. A joint filer at $420,000 is $25,400 over the $394,600 threshold and is within the joint phase-in range.

How the wage-and-property limit works

Above the threshold, the QBI deduction for each qualifying business is generally limited to the greater of:

• 50% of the business’s W-2 wages; or
• 25% of its W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property.

These are alternative calculations; the larger amount is used. Qualified property generally refers to eligible tangible, depreciable property used to produce QBI and still within its applicable depreciable period. The limit is phased in across the $50,000 or $100,000 range. Once taxable income is above the range, the full limit applies. A business with little or no W-2 payroll and little qualified property can therefore face a smaller deduction than a similar business with significant wages or property.

The wage-and-property test is not a direct cap on business profit. It is a separate limitation on the QBI component, and the overall taxable-income ceiling can further reduce the result.

SSTBs and the service-business phaseout

An SSTB is a trade or business in certain service fields, including health, law, accounting, consulting, financial services, and several other specified categories. The statutory definition and detailed rules matter; a business should not be classified solely by its marketing description or an informal list. Engineering and architecture are generally excluded from the SSTB definition, while other fields can require closer analysis.

For a taxpayer within the phase-in range, only a decreasing portion of SSTB income is treated as eligible QBI. Above the top of the range, no QBI deduction is generally allowed for that SSTB income. This restriction is different from the wage-and-property limitation: a non-SSTB may still qualify above the threshold, subject to that limitation, while an SSTB faces the additional service-business restriction.

What income counts—and common misconceptions

The threshold is based on taxable income before the QBI deduction, which may include income beyond the business itself. Taxable income is not the same as business profit: deductions, other income, and filing status can affect it. The deduction is also generally available whether or not a taxpayer itemizes, but that does not remove the eligibility and calculation requirements.

• It is not a business-revenue cutoff. Receipts or gross sales alone do not determine whether a taxpayer is in the phaseout.
• It is not always an all-or-nothing phaseout. The wage-and-property limit phases in; SSTB eligibility is reduced through its range and generally ends above it.
• It is not automatically 20% of profit. The QBI definition, wage-and-property test, SSTB rules, and taxable-income ceiling can all change the amount.
• It is not a deduction for every kind of income. Wage income, investment income, and other nonqualifying items do not become QBI simply because someone owns a business.

How to estimate your position

A useful first pass is to identify the tax year and filing status, then estimate taxable income before the QBI deduction. Compare that amount with the threshold and phase-in range for that year. Next, determine whether the activity is an SSTB, calculate qualified business income, and gather wage and qualified-property figures for any business subject to the limit. Finally, account for the taxable-income ceiling and other applicable adjustments.

Business owners with multiple activities, pass-through entities, trusts, cooperative income, or changing ownership may need more detailed calculations. W-2 wages and qualified property are determined under specific tax rules, and an entity’s reported income is not necessarily identical to an owner’s QBI. Keep the underlying tax forms and business records; do not rely only on a rough comparison with the threshold.

Frequently Asked Questions

What is the QBI deduction phaseout for 2025?
For 2025, the wage-and-property limitation begins above taxable income of $197,300 for non-joint filers and $394,600 for joint filers. The phase-in range is $50,000 or $100,000, respectively. SSTB eligibility is also reduced across that range and generally ends above it.

Is the QBI deduction completely phased out above the threshold?
No. Above the threshold, a non-SSTB business may still qualify, but the wage-and-property limitation applies. SSTB income generally does not qualify once taxable income exceeds the top of the applicable range.

Does the phaseout use adjusted gross income?
The income thresholds use taxable income before the QBI deduction, not adjusted gross income. Taxable income is calculated after applicable deductions and may reflect more than business income.

Can an SSTB claim the deduction below the threshold?
SSTB income can generally qualify when taxable income is at or below the threshold, subject to the overall QBI calculation and taxable-income ceiling. Eligibility is reduced within the phase-in range.

Do these limits apply every year?
Thresholds are year-specific and may be adjusted. Use the figures for the tax year being filed rather than carrying a prior year’s amounts forward.

Checking the rules for your tax year

QBI treatment depends on tax-year-specific thresholds, business classification, and detailed rules for income, wages, and property. Consult the IRS instructions and publications for the applicable year, and consider a qualified tax professional when the classification or calculation is uncertain.
