QBI deduction calculator for freelancers
Most freelancers get 20% of profit off taxable income — until income gets high.
The QBI (qualified business income) deduction lets most freelancers deduct 20% of their business profit from taxable income. It is one of the biggest breaks for people who work for themselves — and it has a threshold trap that catches high earners.
Enter your profit and filing status, and this calculator shows your deduction and the tax it saves.
What the 20% deduction actually is
The Qualified Business Income (QBI) deduction — sometimes called the Section 199A or pass-through deduction — lets most freelancers and sole proprietors deduct 20% of their business income from their federal taxable income. Not from their tax bill: from the income before tax is computed. It is one of the largest breaks available to people who work for themselves, and most new freelancers have no idea it exists.
If your qualified business income is $80,000 and you are below the income threshold, you deduct $16,000 before tax — which at a 22% bracket is about $3,500 you do not send to the IRS. The QBI calculator shows your exact number.
The threshold that changes everything
The full 20% is available only when your total taxable income is below a threshold ($197,300 single / $394,600 married filing jointly for the 2025 tax year). Most solo freelancers sit comfortably under it, so they get the whole deduction with no fuss.
Above the threshold, though, the deduction is limited by how much W-2 wages and qualified property the business has. A solo freelancer with no employees pays themselves no W-2 wages — and that is the trap. With zero wages in the business, the limit collapses toward zero, and a high-earning solo operator can lose most or all of the deduction. The calculator makes this visible: push your income above the threshold with W-2 wages left at zero and watch the deduction shrink.
Why it phases in, not snaps off
The threshold is not a cliff. There is a phase-in range ($50,000 single / $100,000 married above the threshold) where the wage/property limit is gradually applied. Cross the threshold a little and you lose a little; cross it a lot and you lose almost all of the deduction unless you have wages or property to anchor it. The calculator interpolates across that range, so the number moves smoothly rather than jumping.
What counts as QBI
Qualified business income is your net profit from a domestic pass-through business — a sole proprietorship, partnership, S-corp, or LLC — excluding investment income, reasonable S-corp shareholder wages, and a few specified service trades. Crucially, the deduction is computed on the business profit, and it is taken after your ordinary business expenses (the ones the other calculators on this site handle) have already reduced that profit. So the write-offs and the QBI deduction stack: expenses shrink the profit, and then 20% of what remains comes off your taxable income.
The expiration everyone forgets
The QBI deduction was created by the 2017 tax law and is currently scheduled to expire after the 2025 tax year unless Congress extends it. Whether it exists in a given year, and at what thresholds, is a moving target — so treat the thresholds here as a snapshot, verify them at irs.gov for the year you are filing, and do not bake the deduction into a multi-year plan you cannot change.
An estimate for planning, not tax advice. The thresholds and the wage/property limit are simplified here; the real computation also excludes certain service businesses above the threshold and has other wrinkles. The deduction is also scheduled to expire after 2025 unless extended — verify the current year at the IRS QBI page and see the disclaimer.
Frequently asked questions
What is the qualified business income deduction?
It is a federal deduction (Section 199A) that lets most owners of pass-through businesses — sole proprietors, partnerships, S-corps, LLCs — deduct 20% of their qualified business income from taxable income. It is taken on the business profit after ordinary expenses, so it stacks with your other write-offs. For the 2025 tax year it is available below an income threshold of $197,300 single / $394,600 married.
Why do high-earning solo freelancers lose the QBI deduction?
Above the income threshold, the deduction is limited by 50% of the W-2 wages paid by the business (or 25% of wages plus 2.5% of qualified property). A solo freelancer with no employees pays themselves no W-2 wages, so that limit collapses toward zero and the deduction largely disappears. This is the single biggest surprise in the calculation.
Does the QBI deduction reduce my tax or my income?
It reduces your taxable income, not the tax rate. You deduct 20% of QBI before computing tax, so the cash value is 20% of QBI times your marginal rate. On $80,000 of QBI at a 22% bracket, the deduction is worth about $3,500.
Is the QBI deduction permanent?
No. It was created by the 2017 tax law and is currently scheduled to expire after the 2025 tax year unless Congress extends it. Whether it exists in a given year, and at what thresholds, can change — verify the current year at irs.gov before relying on it for planning.
What is the phase-in range?
The threshold is not a cliff. For $50,000 above the threshold (single) or $100,000 (married), the wage/property limit is gradually applied: cross a little and you lose a little, cross a lot and you lose almost all of the deduction unless you have wages or property to anchor it. The calculator interpolates across that range.
Do my ordinary business write-offs affect QBI?
Yes, they feed into it. Your ordinary expenses (home office, mileage, software) reduce your net profit first, and QBI is 20% of the remaining profit. So the write-offs and the QBI deduction work together: expenses shrink the profit, then 20% of what is left comes off your taxable income.
