The QBI deduction (Section 199A): how owners cut taxable income by 20%

A lot of business owners in the United States feel that after working hard all year, the IRS takes more than its share. Most of the time, that comes down to one thing: poor tax planning.

If that's happened to you, keep reading, because this one can save you real money. I want to talk about one of the most powerful and least-used deductions out there: Section 199A of the U.S. tax code, better known as the qualified business income deduction, or QBI deduction.

It can let you deduct up to 20% of your qualified net business income, which directly lowers the income you're taxed on. Here's everything you need to know.

What is the QBI deduction?

The QBI deduction was introduced in 2018 as part of the Tax Cuts and Jobs Act, designed to help small-business owners, independent contractors, consultants, freelancers, and owners of LLCs or S-Corps pay less tax on their net profit.

In plain terms, it lets you deduct up to 20% of your net business income right on your personal return. If your business netted $100,000, you might end up reporting $80,000. That's a direct tax saving.

One thing the older guidance got wrong on timing: the deduction was originally set to expire at the end of 2025. That changed. Under the One Big Beautiful Bill Act, Section 199A continues for 2026, and it actually got better: wider phase-in ranges and a new minimum deduction for small active businesses (more on that below).

Who qualifies?

Not every owner qualifies, and knowing whether you're in or out is how you avoid surprises. The general criteria:

• You own a for-profit business (you're not just an employee).
• You're structured as an LLC, S-Corp, partnership, or sole proprietorship (a pass-through).
• Your taxable income is within the IRS limits (for 2026, the thresholds where the extra rules kick in are $201,775 for single filers and $403,550 for joint filers).
• Your activity qualifies. Most businesses are in, but if yours is a Specified Service Trade or Business (SSTB), there are extra restrictions once your income climbs (more on this next).
• You keep clean books and file correctly.

The SSTB catch (this is the one for service businesses)

This is the part that matters most if you run a service business, and the part that's most often misunderstood.

An SSTB is a "specified service trade or business": fields like health, law, accounting, consulting, financial services, brokerage, performing arts, athletics, and investment management, plus any business whose principal asset is the reputation or skill of its owners.

Here's the key: being an SSTB only hurts you above the income thresholds.

• Below the threshold: SSTB or not, you generally get the full 20% deduction.
• In the phase-out range: the deduction starts shrinking for SSTBs.
• Above the top of the range: an SSTB generally loses the deduction entirely, while a non-SSTB can still claim it if it has enough W-2 wages or qualified property (the formula below).

So if you're a consultant or a financial professional under the threshold, you likely still get the full deduction. The planning question is what happens as your income grows.

A real case: how a client saved over $4,000 with 199A

Nothing explains a tax concept like a real example. This happened to Andrés, a business owner in Florida.

In 2023 he netted a little over $100,000, $110,500 to be exact. He was well within range to claim the deduction, but when our team at FintelAgency™ reviewed his return, we noticed the 199A hadn't been applied. He was about to pay tax on the full amount.

After confirming his structure (a single-member LLC taxed as a sole proprietorship), we applied the 20% deduction, which brought his taxable income down to $88,400. The result: a tax saving of more than $4,400, purely from applying a deduction he already qualified for. (The exact saving depends on his marginal rate; at roughly 20%, a $22,100 deduction saves about $4,400.)

Why this is especially useful for service-business owners

In service businesses, a lot of professionals operate as independents or sole owners, which makes them eligible by default. The problem is that almost no one explains it clearly. This deduction is ideal for:

• Service businesses set up as an LLC or S-Corp.
• Independent professionals who invoice directly as contractors.
• Consultants and advisors with their own practice.

The sad part is that most owners don't even know it exists, or their accountant doesn't apply it because they don't understand it or don't know the industry.

What if your income is above the threshold?

It's not lost if you're over the line, but it comes with conditions that need real planning. Above the threshold (for a non-SSTB), the deduction is capped at the greater of:

• 50% of the W-2 wages the business paid, or
• 25% of those W-2 wages plus 2.5% of the unadjusted basis of qualified property (things like equipment or property used in the business).

In practice, that means if your income is high, you need either a real W-2 wage structure (which ties into whether you should be an S-Corp) or investment in qualifying assets to keep claiming the deduction. The higher you climb, the more your structure decides whether you keep this benefit.

Three things you can do right now

1. Check your legal structure. Are you an LLC, an S-Corp, or just working as an independent with no formal entity? That's the starting point for 199A.
2. Pull your last return. Ask: did my accountant apply this deduction? Did we take the full amount?
3. Get a specialist's eyes on it. Sometimes a 30-minute conversation saves thousands.

Is the QBI deduction going away?

It was originally scheduled to expire after 2025 under the Tax Cuts and Jobs Act, which is why you may have read that it was ending. It isn't. The One Big Beautiful Bill Act kept Section 199A in place for 2026 and beyond, and even improved it: the phase-in ranges got wider ($75,000 for single filers, $150,000 for joint), and there's a new minimum deduction of $400 for owners with at least $1,000 of income from an active business, indexed for inflation. So the 20% deduction is still here, and a little more generous than before.

The problem isn't paying taxes. It's paying more than you owe.

Section 199A, the qualified business income deduction, isn't a secret, but it's one of those hidden gems that separates just working from working with a plan. If you have a business and you qualify, you shouldn't be paying tax on 100% of your income. The money you're not deducting is money you could be reinvesting, saving, or using to grow.

This is one more example of what clean financial and tax structure makes possible. It pays off most alongside the right entity choice (LLC vs S-Corp) and other moves like the Augusta Rule. If you're not sure you're claiming it correctly, let's talk.

Frequently asked questions

What is the QBI deduction?

The qualified business income deduction (Section 199A) lets eligible pass-through owners deduct up to 20% of their qualified net business income on their personal return, lowering taxable income.

How does the QBI deduction work?

You take up to 20% of your qualified business income as a deduction, subject to your taxable income, your business type (SSTB or not), and, above the income thresholds, limits based on W-2 wages and qualified property.

Who qualifies for the QBI deduction?

Owners of pass-through businesses (sole proprietorships, partnerships, LLCs, S-Corps) with taxable income within the IRS limits. Above those limits ($201,775 single / $403,550 joint for 2026), SSTBs face restrictions and other businesses face the wage/property formula.

What business does not qualify for the QBI deduction?

C-Corporations don't (they have their own 21% rate). And Specified Service Trades or Businesses (health, law, accounting, financial services, consulting, and similar) lose the deduction once income rises above the top of the phase-out range. Below the threshold, they generally still qualify.

Is the QBI deduction going away?

No. It was set to expire after 2025, but the One Big Beautiful Bill Act made it continue for 2026, with wider phase-in ranges and a new $400 minimum deduction for small active businesses.

Where do I claim the QBI deduction?

Most people use Form 8995 (the simplified version) or Form 8995-A (when income is above the thresholds), and the deduction flows onto your Form 1040.
