A retiree who picks up consulting work, drives for a rideshare service or runs a small side business is often focused on the income and overlooks a deduction built specifically for that kind of earning. The qualified business income deduction lets eligible taxpayers subtract up to 20% of the net income from a trade or business before calculating what they owe. Created by the 2017 tax overhaul and made permanent under the 2025 tax law, it is one of the larger breaks available to self-employed older adults — and one many never claim because they assume deductions require itemizing.
What income qualifies and how the 20% is calculated
The deduction, found in Section 199A of the tax code, applies to the net qualified business income from a trade or business, including income earned through a pass-through entity such as a sole proprietorship, partnership or S corporation. Wages from a former employer do not count, and neither does income from a C corporation. For a retiree, the qualifying pool is the profit from independent work — a consulting practice, freelance projects, a rental operation that rises to the level of a business, or a small enterprise run in retirement.
The figure is net income, not gross receipts. A consultant who brings in $40,000 but spends $10,000 on business costs is working from $30,000 of qualified business income, and 20% of that — $6,000 — is the starting point for the deduction. That amount then reduces taxable income directly, lowering the tax bill without requiring a single receipt to be itemized on Schedule A.
One feature makes the break unusually accessible: it can be claimed whether or not a taxpayer itemizes, sitting alongside the standard deduction rather than competing with it. Because a large share of retirees take the standard deduction, this matters — the qualified business income deduction is one of the few meaningful write-offs that a standard-deduction filer with self-employment income can still use.

The taxable-income thresholds that change the math
The calculation stays simple only up to a point. Per the 2025 Instructions for Form 8995, a taxpayer whose total taxable income before the deduction is at or below $197,300 for a single filer, or $394,600 for a married couple filing jointly, generally takes the full 20% on the simplified form without further tests. Below those lines, the type of business does not matter and neither do wages paid or property owned.
Above the thresholds, the rules tighten and the longer Form 8995-A comes into play. The deduction becomes subject to limits tied to the W-2 wages a business pays and the cost of its qualified property, and it can be reduced or eliminated for what the tax code calls a specified service trade or business — fields such as consulting, health, law and financial services, where the business’s chief asset is the reputation or skill of its owner. A retired consultant with high total income can watch the deduction phase out precisely because consulting is a service field.
There is also a ceiling that operates regardless of income level. As the IRS guidance explains, the total deduction cannot exceed 20% of taxable income minus net capital gain. A retiree whose income is dominated by capital gains and qualified dividends may find the deduction limited by that overall cap even when the business income itself clearly qualifies, because the taxable-income figure available to be reduced is smaller than it first appears.
Where retirees most often leave the break unclaimed
The most common miss is simply not recognizing that ordinary self-employment counts. A retiree who reports gig or consulting income on Schedule C frequently qualifies for the deduction but never runs the second form, either because tax software did not surface it or because the income felt too small to bother with. Even modest profit produces a real reduction: at a 22% marginal rate, the $6,000 deduction in the earlier example trims roughly $1,320 from the bill.
Retirees who also collect qualified real estate investment trust dividends have a second, separate slice of the same deduction. Those dividends generate their own 20% write-off that is not subject to the wage, property or service-business limits, so a retiree with REIT holdings in a taxable brokerage account can claim it alongside — or even without — any active business income, a detail that often goes unnoticed because it is reported on the same form as the business figure.
The deduction is claimed on Form 8995 for those under the income thresholds, or Form 8995-A above them. The practical decision for a self-employed older adult is less about whether the income qualifies — most independent work does — and more about watching total taxable income near the thresholds, since crossing them shifts the deduction from an automatic 20% into a test that can shrink the benefit or, for a service business, erase it entirely.
