Section 199A QBI Deduction for Schedule C Filers: Thresholds and Limits

For the 2026 tax year, the Section 199A QBI deduction for Schedule C filers is worth up to 23% of your qualified business income, and it is now a permanent part of the tax code.¹ The One Big Beautiful Bill Act raised the rate from 20%, removed the sunset that would have ended the deduction after 2025, and widened the phase-in range for middle-income filers. The catch: at higher income levels, the deduction is limited by the W-2 wages you pay and the depreciable property you own, which can shrink it to zero for a solo freelancer with no employees.

Which Rate Applies to Which Tax Year

The 23% rate applies to income earned starting January 1, 2026.¹ For the 2025 tax year, filed in early 2026, the old 20% rate and prior thresholds still control.² If you are planning quarterly estimated payments for 2026, use the higher rate; if you are finalizing a 2025 return, use 20%.

What Counts as Qualified Business Income

Start with the net profit on your Schedule C, then reduce it by three items: the deductible portion of your self-employment tax, contributions to qualified retirement plans such as a SEP-IRA or Solo 401(k), and any self-employed health insurance premiums you deducted.³ What remains is your qualified business income for that activity.

Several categories of income are stripped out even if they flow through the business:

Capital gains and losses, short-term or long-term
Interest income, unless it is directly tied to business operations
Dividends from investments
Foreign currency and commodity transaction gains

The deduction targets operational profit, not investment returns that happen to sit inside the business.³ If your business checking account earns interest, that interest is not QBI. Keep your books clean enough to separate the two.

The business also has to operate in the United States. Foreign income and income from certain U.S. territories do not count.⁴ Whether you file as a sole proprietor or a single-member LLC makes no difference, since both report on Schedule C. And your activity must be a trade or business pursued regularly for profit; if the IRS treats it as a hobby, no deduction is available.⁵

The Taxable Income Ceiling

Your deduction is the lesser of two figures: your combined QBI amount, or 23% of your taxable income minus any net capital gain.⁴ The second cap matters when capital gains are a large share of your income. If your total taxable income is $150,000 but $50,000 comes from capital gains, the 23% rate applies only to the remaining $100,000, capping your deduction at $23,000 regardless of how large your QBI was.

The deduction also cannot generate a net operating loss. It can reduce your taxable income to zero, but it cannot go below.

Income Thresholds That Change Everything

Below a certain taxable income level, the calculation is simple: 23% of QBI, subject to the ceiling above. For 2026, those thresholds are approximately $201,750 for single filers and $403,500 for joint filers, based on the inflation-adjusted amounts under the new law.¹ These figures refer to your total taxable income before the QBI deduction is subtracted.

Once your income crosses the lower threshold, two limitations begin to phase in over a range of roughly $75,000 for single filers and $150,000 for joint filers. By approximately $276,750 (single) or $553,500 (joint), the limitations apply in full. Inside the phase-in range, the deduction shrinks by about $0.75 for every dollar of taxable income above the lower threshold.

For the 2025 tax year, the confirmed thresholds are $197,300 (single) and $394,600 (joint), with phase-ins completing at $247,300 and $494,600.² Verify the final 2026 figures against the Form 8995 and 8995-A instructions once the IRS releases them.

The W-2 Wage and Property Limitation

This is where many high-earning Schedule C filers get a bad surprise. Once your taxable income clears the phase-in range, the deduction for each business is capped at the greater of:⁴

50% of the W-2 wages the business paid, or
25% of W-2 wages plus 2.5% of the unadjusted basis of depreciable business property still within its recovery period

A solo freelancer with no employees has zero W-2 wages. With no depreciable property, both calculations produce zero, and the deduction disappears entirely above the upper threshold. Consultants, designers, and other service providers who work alone are the most likely to run into this.

The property component uses “unadjusted basis immediately after acquisition,” which is the original purchase price before any depreciation.⁶ Property counts only while it is still depreciable; once the longer of 10 years or the full recovery period has passed, it drops out. A $5,000 laptop barely moves the calculation. A $200,000 piece of equipment or a building used in the business can preserve a meaningful deduction.

Specified Service Trades and Businesses

An additional restriction hits professional fields where the value of the business comes from the expertise or reputation of the people doing the work. Federal regulations list them:⁷

Health care
Law
Accounting
Actuarial science
Performing arts
Consulting
Athletics
Financial services and brokerage services
Investing, investment management, and trading
Any business whose main asset is the reputation or skill of its owners or employees, limited to endorsement income, licensing of a person’s image or likeness, and appearance fees

Below the lower income threshold, the SSTB label has no effect and you get the full deduction. Inside the phase-in range, a shrinking share of SSTB income qualifies. Above the upper threshold, the SSTB deduction is gone entirely.⁸

Two fields are notably absent from the list: engineering and architecture. Congress carved them out. A freelance engineer or architect is treated the same as any non-service business, and the SSTB restrictions never apply regardless of income.⁴

The “reputation or skill” catchall sounds broad but is defined narrowly. Owning a restaurant does not make you an SSTB because the chef is talented. The category reaches only endorsement fees, image licensing, and paid appearances. A consultant earning fees for advising clients falls under “consulting” instead.

When Your Business Has a Loss

A net loss on your Schedule C produces no QBI and no deduction that year. The loss carries forward indefinitely as a negative QBI amount that offsets future qualified business income until absorbed.⁸

With multiple businesses, a loss from one is netted against the others’ profits before you calculate the deduction, and it is spread proportionally across the profitable ones. Once a loss reduces a profitable business’s QBI to zero, the W-2 wages and depreciable property from that profitable business also drop out of the deduction calculation.⁸ Track the carryforward amount carefully; it continues to reduce your deduction in future years even after the loss-generating business is closed.

Running More Than One Schedule C

By default, each Schedule C business is a separate trade or business for QBI purposes, and the calculations run independently. You can elect to aggregate certain businesses and treat them as one, which helps when one activity has strong W-2 wages or property and another does not. To aggregate, all of the following must be true:⁹

You own 50% or more of each business.
None of them is an SSTB.
The businesses share at least two of these three: similar or complementary products and services; shared facilities or centralized operations such as accounting or IT; or coordinated operations, such as a supply chain relationship.

Aggregation, once made, must continue every year unless the underlying facts change enough to disqualify it. You report the grouping on Schedule B of Form 8995-A each year. Miss that disclosure and the IRS can undo the aggregation and bar you from re-aggregating those businesses for three years.⁹

Filing the Deduction

The deduction appears on Form 1040 after adjusted gross income, working alongside the standard or itemized deduction to reduce taxable income. It does not reduce self-employment tax, which is still calculated on the full net profit from your Schedule C.³

Which form you file depends on your income:

Form 8995 is the simplified version, available if your taxable income is at or below the lower threshold and you are not a patron of an agricultural or horticultural cooperative.²
Form 8995-A is required if your income exceeds the threshold, if you operate an SSTB, or if you are aggregating businesses. It includes additional schedules for the W-2 wage and property limitations.⁸

Attach the completed form to your return.¹⁰ Tax software will walk you through the inputs, but if losses, aggregation, or SSTB income are involved, check that the correct figures land on each schedule.

A Lower Penalty Threshold You Should Know About

Congress lowered the accuracy-related penalty trigger specifically for taxpayers claiming this deduction. The substantial understatement penalty normally applies when the understatement exceeds 10% of the tax you should have reported. For anyone claiming Section 199A, that trigger drops to 5%.¹¹

The penalty itself is 20% of the underpayment. If you owed $20,000 in tax and understated by $1,000, you have hit the 5% threshold. On a different part of your return, you would have needed a $2,000 understatement to be exposed to the same penalty.

You can avoid the penalty by showing reasonable cause and good faith, and the IRS weighs the effort you put into getting the calculation right.¹² Reliance on a tax professional can qualify, but only if you gave them complete and accurate information. Handing over a rough profit figure and skipping details about investment income or losses in another business will not hold up. Given the moving parts, thorough records and, where the numbers warrant it, professional help pay off here.
