QBI Deduction is Now Permanent: How to Maximize Your 20%

QBI Deduction is Now Permanent: How to Maximize Your 20%

I was at the Austin CPA Society dinner last month when the news broke. Someone checked their phone mid-speech and announced: "OBBBA passed. QBI is permanent." The room erupted. Not with joy—CPAs do not do joy—but with relief. Twelve years of temporary extensions, sunset provisions, and congressional brinksmanship. Finally, permanence.

Here is why this matters, and how to make sure you are getting every dollar you deserve.

What Is QBI?

Qualified Business Income (QBI) deduction, also known as Section 199A, lets eligible self-employed individuals and small business owners deduct up to 20% of their qualified business income. This applies to pass-through entities: sole proprietorships, partnerships, S-Corps, and some trusts and estates.

The deduction is taken at the owner level, not the business level. Whether you itemize or take the standard deduction, you can claim QBI. It is an above-the-line deduction that reduces your taxable income.

The OBBBA Made It Permanent

Before the OBBBA, QBI was scheduled to expire after 2025. Every year, business owners had to plan as if it might disappear. Now it is permanent. This changes everything about long-term business planning, entity selection, and retirement strategy.

I have a restaurant owner client in South Austin. S-Corp, $340,000 annual net income. His QBI deduction saves him roughly $14,000 per year in federal tax. Over ten years, assuming no income growth, that is $140,000. With growth, it could be $200,000+. "Permanent" means he can factor that into expansion plans, equipment purchases, hiring decisions.

How the 20% Calculation Works

It is not simply 20% of your business profit. It is the LESSER of:

20% of your QBI, OR 20% of your taxable income before the QBI deduction (minus net capital gains).

So if your business nets $100,000 but your taxable income is only $60,000 after other deductions, your QBI deduction is capped at 20% of $60,000 = $12,000, not 20% of $100,000 = $20,000.

This is why retirement contributions matter so much for QBI optimization. Every dollar you put into a 401(k) or SEP reduces your taxable income, which might reduce your QBI deduction—but it also reduces your tax rate. The interplay is complex. I run three scenarios for every business client.

The Limitation Thresholds for 2026

The OBBBA expanded the phase-in ranges. For 2026:

Threshold amount: $201,775 (single) / $403,500 (joint)
Full phase-in: $276,775 (single) / $553,500 (joint)

Between these amounts, your deduction phases in based on W-2 wages paid and qualified property basis. Below the threshold? You get the full 20% (subject to taxable income cap). Above the full phase-in? Your deduction is limited to the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of qualified property basis.

This is where S-Corp vs sole proprietor decisions get critical. I actually compared these entity types in detail recently—if you are on the fence about your business structure, that breakdown covers how QBI limitations interact with payroll strategy.

Specified Service Trades or Businesses (SSTB)

Doctors, lawyers, accountants, consultants, financial advisors, athletes, performers—if your business is an SSTB, the QBI deduction phases out completely above the full phase-in amount. Non-SSTB businesses face limitations but not elimination.

I am an SSTB (CPA/accounting). My QBI deduction is fully phased out at my income level. I knew this when I structured my practice. I still help clients optimize theirs. The irony is not lost on me.

A doctor client of mine—cardiologist, $480,000 income—hits the SSTB phase-out. His QBI deduction is zero. But his wife runs a non-SSTB rental property business netting $45,000. She gets the full 20% ($9,000 deduction). They file jointly, so her deduction applies against their combined taxable income. Entity separation saved them $9,000.

Strategies to Maximize QBI

Strategy 1: Income Splitting. If you are near the threshold, consider contributing more to retirement accounts, HSA, or making charitable donations to reduce taxable income and stay under the phase-out.

Strategy 2: W-2 Optimization (Non-SSTB). If you are above the threshold, paying yourself reasonable W-2 wages increases your wage-based limitation. An S-Corp owner with $300,000 profit and $0 wages gets limited QBI. Same owner with $100,000 W-2 wages and $200,000 distribution gets a higher limitation.

Strategy 3: Property Basis. Buying qualified business property increases your 2.5% basis limitation. A $400,000 building adds $10,000 to your annual limitation calculation. Depreciable life must be 10 years or less (or real property with longer life under special rules).

Strategy 4: Separate SSTB from Non-SSTB. If you have multiple business activities, consider separating them. A doctor who also owns medical office real estate might structure the real estate as a separate LLC to capture QBI on the rental income.

Common Mistakes

Claiming QBI on W-2 wages (not allowed). Claiming it on capital gains or investment income (not allowed). Missing the SSTB phase-out and claiming full deduction (audit bait). Not tracking qualified property basis properly. Failing to optimize W-2 vs distribution ratio in S-Corps.

I audited a financial advisor in 2017 who claimed QBI on his entire $220,000 income. SSTB. Above threshold. Deduction should have been zero. He owed $12,400 in back tax plus penalties. "My software calculated it," he said. Software does not know your business type unless you tell it.

The Planning Horizon

Permanent QBI means you can make multi-year decisions. Should you buy that equipment this year or next? Should you hire an employee (increasing W-2 wages and your limitation)? Should you convert to S-Corp? Should your spouse start a side business?

I run five-year projections for my business clients now. Before OBBBA, I ran one-year projections with caveats. Permanence changes the math. It changes the strategy. It changes everything.

The QBI Deduction and Real Estate

Real estate investors often overlook QBI. If your real estate activity rises to the level of a trade or business (not just passive investment), you may qualify for the 20% deduction. The IRS has a safe harbor: if you spend at least 250 hours annually on the activity and maintain contemporaneous records, you qualify.

I have a client who owns four rental properties in Austin. He spends roughly 300 hours annually managing them: tenant screening, maintenance coordination, rent collection, bookkeeping. He qualifies for the safe harbor. His net rental income: $45,000. QBI deduction: $9,000. Tax savings at 24%: $2,160. "I did not know this existed," he said when I told him. Most real estate investors do not.

But be careful. If you use a property manager who handles everything, you might not meet the 250-hour threshold. The IRS looks at who does the work. If your property manager spends 280 hours and you spend 20, you do not qualify. The hours must be YOURS.

The Aggregation Election

Business owners with multiple pass-through entities can elect to aggregate them for QBI purposes. This is powerful when one business has high QBI but low wages/property, and another has low QBI but high wages/property.

Example: You own a consulting business (SSTB, $200,000 income, no wages, no property) and a rental property business (non-SSTB, $50,000 income, $30,000 wages to property manager, $400,000 property basis). Separately: consulting QBI is fully phased out at your income level. Rental QBI gets a limitation of $15,000 (50% of wages) or $16,000 (25% wages + 2.5% property). Deduction: roughly $3,200.

Aggregated: Combined QBI: $250,000. Combined wages: $30,000. Combined property: $400,000. Limitation: $15,000 (50% wages) or $17,500 (25% wages + 2.5% property). 20% of $250,000 = $50,000. Limited to $17,500. Deduction: $17,500.

Aggregation increased the deduction from $3,200 to $17,500. Tax savings at 32%: $4,576. That is real money.

But aggregation has rules. The businesses must share common ownership (50%+). They must share facilities or centralized business elements (accounting, HR, legal). They must operate in coordination or reliance with each other. Not all businesses can aggregate.

I had a client try to aggregate his dental practice and his personal investment LLC. The IRS denied it. "No common business purpose," they said. "No coordination." He owed $8,400 in back tax. Aggregation is powerful, but it has boundaries.

QBI and Partnerships

Partnerships add complexity. The QBI deduction flows through to partners based on their distributive share. But the wage and property limitations are calculated at the partnership level, then allocated to partners.

Example: A partnership has $500,000 QBI, $100,000 W-2 wages, and $800,000 qualified property. Two equal partners. Each gets $250,000 QBI. Partnership-level limitation: greater of 50% wages ($50,000) or 25% wages + 2.5% property ($25,000 + $20,000 = $45,000). Limitation: $50,000. Allocated equally: $25,000 per partner.

Each partner's deduction: lesser of 20% of $250,000 ($50,000) or $25,000 (allocated limitation). Deduction: $25,000 each. Total partnership deduction: $50,000.

If one partner is above the SSTB threshold and the other is below, things get messy. The SSTB partner might be fully phased out while the non-SSTB partner gets the full deduction. Partnership agreements should address QBI allocation, but most do not.

I reviewed a partnership agreement last month that was silent on QBI. Three partners. One is a doctor (SSTB, high income, phased out). Two are administrators (non-SSTB, moderate income, full deduction). The doctor wanted QBI allocated equally. The administrators wanted it allocated by income. "We will figure it out at tax time," the agreement said. That is not a plan. That is a lawsuit waiting to happen.

The Future of QBI

Permanent does not mean immutable. Congress can change any tax law. But permanence signals stability. Business owners can plan five-year, ten-year, twenty-year strategies around QBI. They can make capital investments knowing the deduction will be there. They can hire employees knowing wages will count toward limitations.

Before permanence, every December was a guessing game. Will Congress extend? Will they modify? Will they let it expire? Now, the guessing is over. The deduction is here. Plan accordingly.

I am running a 10-year projection for a manufacturing client right now. He is considering a $2 million equipment purchase. Under bonus depreciation (also extended by OBBBA), he can deduct 60% immediately in 2026. The remaining 40% depreciates over 7 years. The equipment increases his qualified property basis for QBI. The wages for new operators increase his wage limitation. The net effect: $400,000 in QBI deduction over 7 years, plus $480,000 in bonus depreciation. Total tax savings: roughly $280,000.

"Permanent QBI made this decision easy," he told me. "Before, I would have hesitated. Now, I know the rules."

That is the power of permanence. Certainty. Planning. Confidence. After twelve years of temporary provisions and sunset cliffs, it is refreshing to have a tax provision we can actually rely on.
