Qualified business income (QBI) deduction

The QBI deduction, section 199A, lets owners of sole proprietorships, partnerships, LLCs and S corporations deduct up to 20% of their business profit. The July 2025 tax law made it permanent, and from 2026 it widens the income ranges and adds a $400 minimum deduction.

How much it is

The deduction is generally the smaller of two amounts: 20% of your qualified business income, plus 20% of qualified REIT dividends and publicly traded partnership income, or 20% of your taxable income minus net capital gain. You take it whether or not you itemize.

It lowers income tax only. It does not reduce self-employment tax, and it comes after adjusted gross income, so it does not lower Illinois tax, which starts from federal AGI.

Wages from a job and income earned through a C corporation do not count.

Example: a self-employed driver

A single filer has $60,000 of Schedule C profit in 2026 and no other income. Qualified business income is the profit minus the deductible half of self-employment tax, about $4,239, so it is $55,761, and 20% of it is $11,152.

But taxable income before the deduction is $55,761 minus the $16,100 standard deduction, or $39,661, and 20% of that is $7,932. The smaller amount wins: the QBI deduction is $7,932.

The income limits

Below the threshold, the deduction is simple and Form 8995 is used. Above it, two limits phase in over the next $75,000 ($150,000 joint) and Form 8995-A is used:

Specified service businesses, such as health, law, accounting, consulting, financial services, athletics and performing arts, lose the deduction gradually and get none above the top of the range. Other businesses are limited to the greater of 50% of the W-2 wages they pay, or 25% of wages plus 2.5% of the original cost of their qualified property.

The new $400 minimum

From 2026, if you have at least $1,000 of qualified business income from businesses you actively run, meaning you materially participate in them, your deduction is at least $400. Both amounts rise with inflation after 2026. It helps people with small side businesses whose deduction would otherwise be tiny.

S corporation owners

The salary an S corporation pays its owner is wages, not qualified business income. Each extra dollar of salary adds payroll tax and takes a dollar out of the profit the 20% applies to, but the salary has to be reasonable for the work, so the level is a trade-off worth working out each year. Above the threshold, the wages the S-Corp pays can also be what keeps the deduction from being limited.

For S-Corp owners and growing businesses, the QBI deduction depends on salary, wages and timing. Our tax planning assessment works it out on your own numbers. $195, in Naperville, IL, by phone or by Zoom.
