How It Works

This calculator determines your Qualified Business Income (QBI) deduction under Section 199A of the IRS tax code. This deduction can significantly reduce the taxable income for eligible self-employed individuals and small business owners, leading to substantial tax savings.

The calculator identifies your QBI, W-2 wages, and unadjusted basis of qualified property. It then calculates the lower of 20% of your QBI or 20% of your taxable income (before the QBI deduction and capital gains), subject to various income limitations and W-2 wage/property limitations for specified service trades or businesses (SSTBs) and non-SSTBs.

Incorrectly classifying your business as an SSTB or non-SSTB is a common mistake that can significantly impact your deduction. Also, be mindful of the taxable income thresholds that trigger the W-2 wage and property limitations, as these can reduce or eliminate the deduction.

Example: Freelance Graphic Designer

  1. 1 Sarah, a single freelance graphic designer, has $100,000 in QBI, $0 in W-2 wages, $0 in unadjusted basis of qualified property, and a taxable income (before QBI deduction) of $90,000. Her business is not an SSTB.
  2. 2 The calculator first determines 20% of her QBI ($100,000 * 0.20 = $20,000) and 20% of her taxable income ($90,000 * 0.20 = $18,000). Since her taxable income is below the threshold for W-2 wage and property limitations, the lower of these two amounts is her preliminary deduction.
  3. 3 Sarah's QBI deduction is $18,000.
  4. 4 This $18,000 deduction reduces Sarah's taxable income, resulting in a lower tax liability. It's crucial to understand how your business classification and income level affect the available deduction before filing.

Frequently Asked Questions

What is the QBI deduction?
The Section 199A QBI deduction allows owners of pass-through businesses (S-corps, partnerships, sole proprietorships) to deduct up to 20% of their qualified business income. On $200,000 of QBI, this could save $40,000 from taxable income, worth $8,800-$14,800 in taxes depending on your bracket.
What is the income limit for the full QBI deduction in 2026?
Below $200,000 (single) or $400,000 (married filing jointly) of taxable income, the full 20% deduction is generally available regardless of business type. Above these thresholds, the deduction may be limited by W-2 wages paid, and certain specified service businesses (SSTBs) like law, medicine, and consulting face phase-outs.
Do doctors and lawyers get the QBI deduction?
Specified service businesses (law, medicine, accounting, consulting, athletics, financial services) receive the full QBI deduction below the income thresholds. The deduction phases out between $200,000-$250,000 (single) and $400,000-$500,000 (married). Above the upper threshold, SSTBs get zero QBI deduction.
