How these estimates work. They use the 2026 federal brackets and standard deductions from IRS Rev. Proc. 2025-32 and the 2026 Social Security wage base of $184,500. Self-employment tax is figured on 92.35% of net profit. The QBI deduction is included at 20% only below the 2026 threshold ($201,750, or $403,500 married filing jointly). State and local tax, the 0.9% Additional Medicare Tax, itemized deductions and any credit you don't enter are left out. Your actual result depends on your full return.
