❓ QBI Deduction FAQ 2026
What are the 2026 QBI deduction phase-out thresholds for married couples filing jointly?
For 2026 (projected based on inflation), the phase-out range for Married Filing Jointly is expected to be $390,000 to $490,000. Below $390,000, you get the full 20% QBI deduction. Between $390,000-$490,000, Specified Service Businesses face gradual phase-out, while other businesses become subject to wage/capital limits. Above $490,000, SSTBs get no deduction, while other businesses remain subject to limits.
How do I calculate QBI for my Schedule C business?
Qualified Business Income (QBI) is generally your net business profit from Schedule C, Line 31, minus: 1) Self-employment tax deduction, 2) Self-employed health insurance deduction, 3) Retirement plan contributions, plus: 1) W-2 wages paid to yourself (if S Corp), 2) Guaranteed payments (if partnership). Our QBI calculator 2026 handles these adjustments automatically when you input your business income and relevant expenses.
What happens to the QBI deduction after 2025?
The QBI deduction is currently scheduled to sunset after December 31, 2025 unless extended by Congress. However, most tax experts expect at least a partial extension, and our 2026 calculations include projected inflation adjustments and potential legislative scenarios. Always consult a tax professional for the most current information as laws may change.
Can I still get the QBI deduction if my business has a loss?
If your business has a net loss for the year, you get no QBI deduction for that year. Instead, the loss reduces your QBI in future years (carryforward). The loss is allocated proportionally to each business activity, and special rules apply for "excess business losses" under Section 461(l). Our calculator accounts for loss scenarios and carryforward implications.
How do W-2 wages affect my QBI deduction calculation?
W-2 wages play two roles: 1) For taxpayers above the income threshold, the QBI deduction is limited to the greater of 50% of W-2 wages OR 25% of W-2 wages + 2.5% of UBIA. 2) W-2 wages paid to owners of S Corporations count toward the limit but are not included in QBI itself. For sole proprietors with no employees, this limit can be restrictive, making entity structure planning important.
