What is the Qualified Business Income (QBI) deduction?
The QBI deduction allows eligible business owners to deduct up to 20% of their qualified business income from their taxable income. If your business earns $100,000 in qualified income, you could potentially deduct $20,000, reducing the amount you pay taxes on. For many small business owners, this is one of the largest tax benefits available.
This deduction applies to pass-through entities. That means sole proprietorships, partnerships, S corporations, and most LLCs. C corporations don’t qualify because they’re taxed under a different structure. The income must come from a trade or business conducted within the United States. Investment income, reasonable compensation you pay yourself from an S corp, and guaranteed payments to partners don’t count toward QBI.
Income thresholds add complexity. For 2024, the deduction phases out for single filers between $191,950 and $241,950 and for married filing jointly between $383,900 and $483,900. Below these thresholds, most business owners can claim the full 20%. Above them, additional limitations kick in based on W-2 wages paid and the value of qualified property held by the business.
Certain service businesses face extra restrictions. Health, law, accounting, consulting, financial services, and a few other fields are classified as “specified service trades or businesses.” If you’re in one of these categories and your income exceeds the threshold, your deduction gets reduced or eliminated entirely. A doctor earning $500,000 might get no QBI deduction at all while a contractor earning the same amount might get the full benefit.
Your entity structure and how you pay yourself directly affect the calculation. Business tax preparation that accounts for QBI planning can make a real difference in your tax bill. The deduction isn’t automatic and it isn’t one-size-fits-all.
Year-round tax planning helps maximize this benefit. Waiting until April to think about QBI means missed opportunities to adjust income, structure payments, or time decisions in ways that increase your deduction. Small business bookkeeping that keeps your records accurate throughout the year makes it possible to run these calculations before the year ends instead of discovering what you could have done differently.
The QBI deduction is valuable but it rewards those who plan ahead. Understanding whether you qualify and what limits apply to your situation is the first step toward actually capturing the savings.
