How we worked it out
Updated as you change the numbers.
- AGI = $85,000.00 − $6,000.00 pre-tax deductions = $79,000.00.
- Taxable income = $79,000.00 − $16,100.00 deduction = $62,900.00.
- Each slice of taxable income is taxed at its bracket's rate, giving $8,550.00.
Method and assumptions
The 2026 brackets and standard deductions come from IRS Revenue Procedure 2025-32. Only the part of your taxable income inside each bracket is taxed at that bracket's rate, so moving into a higher bracket never reduces your take-home pay. The standard deduction for 2026 is $16,100.00 for single filers, $32,200.00 for married couples filing jointly and $24,150.00 for heads of household, plus $1,650.00 (married) or $2,050.00 (unmarried) for each person 65 or older or blind.
