A freelance graphic designer earning $120,000 a year can now shield $24,000 of that income from federal taxes, not just this year but every year going forward. A two-partner accounting firm splitting $400,000 in profits can each deduct up to $40,000. And the owner of a small plumbing company clearing $200,000 through an S-corporation can keep as much as $40,000 off the taxable ledger, with no expiration date looming.
These are not hypothetical scenarios. They are the direct result of Section 70105 of the One, Big, Beautiful Bill Act, signed into law on July 4, 2025. That provision made permanent the qualified business income (QBI) deduction under Internal Revenue Code Section 199A, a tax break first created by the 2017 Tax Cuts and Jobs Act that had been set to vanish after December 31, 2025. For the roughly 30 million pass-through business returns filed each year, according to IRS Statistics of Income data, the change swaps a ticking clock for a permanent fixture in the tax code.
Who qualifies and how the math works
The deduction is available to sole proprietors filing Schedule C, partners and LLC members receiving Schedule K-1 allocations, S-corporation shareholders, and certain trusts and estates. It also covers qualified REIT dividends and income from publicly traded partnerships. Eligible taxpayers claim it on their individual returns using Form 8995 or Form 8995-A for more complex situations.
The core calculation is simple: take your qualified business income and multiply by 20%. Then compare that figure against 20% of your taxable income before the QBI deduction itself. You get the lesser of the two. So a sole proprietor with $100,000 in qualified business income but only $95,000 in taxable income would deduct $19,000 (20% of $95,000), not $20,000.
To see how the deduction scales at different income levels, consider these additional examples:
| Filing status | Qualified business income | Taxable income (before QBI deduction) | Approximate QBI deduction |
|---|---|---|---|
| Single, freelance writer | $60,000 | $48,000 | $9,600 (20% of $48,000) |
| Married filing jointly, consulting LLC | $150,000 | $140,000 | $28,000 (20% of $140,000) |
| Single, e-commerce sole proprietor | $250,000 | $230,000 | Up to $46,000, subject to W-2 wage and property caps |
| Married filing jointly, S-corp owners | $500,000 | $480,000 | Up to $96,000, subject to W-2 wage and property caps |
These figures are simplified illustrations. Actual results depend on filing status, other deductions, and whether the wage-and-property limitations apply.
For higher earners, guardrails tighten the benefit. Once taxable income crosses certain thresholds, the deduction is capped by the greater of 50% of W-2 wages the business pays, or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property (think equipment, buildings, and other depreciable assets). These limits, detailed in the Treasury Department’s final regulations published in February 2019 (Treasury Decision 9847), remain unchanged under the new law. They hit hardest for owners of capital-light businesses, like consultants or freelancers, who pay few or no W-2 wages and hold little depreciable property.
The specified service trade or business question
Doctors, lawyers, accountants, consultants, financial advisors, and other professionals in what the tax code labels “specified service trades or businesses” (SSTBs) face an extra hurdle. Below the income thresholds, they qualify for the full 20% deduction just like any other pass-through owner. But as taxable income climbs into the phase-in range, the deduction shrinks and eventually disappears entirely.
For the 2025 tax year (the last year before the permanence provision took effect mid-year), the phase-in range for single filers ran from $191,950 to $241,950, and for married couples filing jointly from $383,900 to $483,900. The One, Big, Beautiful Bill Act adjusted the phase-in range amounts under Section 199A(b)(3), and the codified text of Section 199A reflects these updated figures as of May 2026. Because these thresholds are now indexed for inflation going forward, the exact dollar amounts for the 2026 tax year will be set by IRS revenue procedures later in 2026. Taxpayers close to those boundaries should review the current statutory language or work with a tax professional before year-end, because a few thousand dollars of additional income in or near the phase-in zone can dramatically reduce the benefit.
One quirk worth noting: engineering and architecture were carved out of the SSTB definition when the original law was written in 2017, and that carve-out survives. An architect earning well above the thresholds can still claim the deduction (subject to the wage-and-property caps), while a similarly paid attorney cannot. Congress never explained the distinction in a way that satisfied critics, but it remains the law.
What permanence actually changes for business owners
The mechanics of computing the deduction are largely the same as they have been since 2018. What shifted is the planning horizon, and for many small-business owners, that matters more than any formula.
Under the original Tax Cuts and Jobs Act, Section 199A was set to sunset after 2025. That expiration date forced owners into a guessing game every fall: Should I accelerate income into this year to capture the deduction while it lasts? Should I delay a major equipment purchase until I know whether the break survives? Should I convert my LLC to an S-corporation now or wait to see what Congress does?
With the deduction locked in permanently, those questions lose their urgency. A sole proprietor weighing a $50,000 equipment investment can evaluate the purchase on its business merits without factoring in legislative risk. An S-corporation owner calibrating her salary, which directly affects both payroll taxes and the QBI calculation, can optimize the split between wages and distributions knowing the rules will hold.
Retirement planning benefits too. Contributions to a SEP-IRA or solo 401(k) reduce qualified business income, which in turn reduces the QBI deduction. That tradeoff between retirement savings and current-year tax savings has always existed, but owners can now model it over a multi-decade career rather than a single legislative window that might slam shut.
The revenue cost and who benefits most
Making the deduction permanent is not free. The Joint Committee on Taxation’s distributional analysis, published as JCX-37-25, estimated that extending Section 199A permanently would reduce federal revenue by roughly $700 billion over the standard ten-year budget window. While the JCT document shows how benefits are distributed across income groups, it does not break out impacts by industry or state, leaving gaps in the policy debate.
Critics of the deduction have argued since 2017 that it disproportionately benefits higher-income pass-through owners, particularly those in real estate, finance, and professional services. Supporters counter that the provision reaches millions of small operators, from Etsy sellers to independent truckers, who would otherwise face a higher effective tax rate than C-corporations benefiting from the permanent 21% corporate rate.
For individual tax planning, the policy debate is secondary. What matters is whether you qualify and how much you can deduct, questions answered by the statute and Treasury regulations rather than by revenue tables.
Interaction with the SALT cap in the same law
The One, Big, Beautiful Bill Act also raised the cap on the federal deduction for state and local taxes (SALT) to $40,000 for most filers. For pass-through owners who itemize, the two provisions interact in a meaningful way. A higher SALT deduction lowers taxable income, and because the QBI deduction is capped at 20% of taxable income (before the QBI deduction), a larger SALT write-off can, in some cases, slightly reduce the QBI benefit. Conversely, for SSTB owners near the phase-in thresholds, a bigger SALT deduction could push taxable income below the range where the deduction begins to phase out, effectively preserving more of the 20% benefit. Owners in high-tax states should model both provisions together rather than in isolation.
Open questions heading into the second half of 2026
Several important pieces of the picture remain incomplete as of June 2026. The IRS has not released post-July 2025 Statistics of Income figures, so there is no reliable way to measure whether permanence has triggered a wave of new Schedule C filings or shifted how owners choose between entity structures. Any claims about a surge in new businesses or large-scale restructuring remain speculative until that data arrives.
The Congressional Research Service has published background analysis on Section 199A’s design and policy rationale, but no updated CRS estimates address behavioral responses, such as whether permanence will encourage more workers to reclassify as independent contractors to capture the deduction. That concern has followed the provision since its inception, and the answer depends on enforcement patterns and future Treasury rulemaking that have not yet been announced.
State conformity adds another layer. Most states that impose an income tax use federal adjusted gross income or federal taxable income as their starting point, which means the QBI deduction often flows through automatically. But not all states conform, and some decouple from specific federal provisions. A deduction that saves $8,000 on a federal return may do nothing on a state return in a decoupled state. Business owners should verify their state’s conformity status before assuming the full benefit.
How pass-through owners should use the permanent deduction in 2026 planning
For the millions of Americans already claiming the QBI deduction, the immediate action item is straightforward: keep doing what you have been doing, but with greater confidence. The forms, the calculations, and the eligibility rules are functionally the same. The difference is that you no longer need to treat the deduction as a temporary benefit that might vanish with the next Congress.
For those who have been on the fence about starting a business, converting an entity, or restructuring their compensation, permanence removes one layer of uncertainty. It does not, on its own, make any of those decisions wise or unwise. The QBI deduction is one factor among many, including self-employment taxes, liability protection, state tax treatment, and the actual economics of the business itself.
The strongest move any pass-through owner can make right now is to revisit their tax projections with a qualified professional who understands the post-amendment rules. The 20% deduction is no longer a temporary gift from a single piece of legislation. It is a permanent feature of the Internal Revenue Code, and the planning around it should be just as durable.
