How the 2026 income tax calculator works
The calculator uses 2026 federal income tax brackets, an estimated 2026 standard deduction, and a simple state income tax model to give you a clean planning estimate in one place.
Step 1: Estimate your 2026 taxable income
Annual income (all sources you enter)
− estimated 2026 standard deduction
= estimated federal taxable income
First, the calculator annualizes your income based on the pay frequency you choose. If you enter monthly income, it multiplies by 12. If you enter hourly income, it multiplies your hourly rate by your hours per week and then by 52 weeks.
Example: A single filer with a 2026 annual salary of $70,000 and no other income uses an estimated $16,100 standard deduction. The tool subtracts this estimate and runs the remaining amount through the 2026 federal brackets.
Step 2: Apply an effective state income tax rate
State income tax ≈ Annual income × estimated state effective rate
State income tax rules are different in every state and city. To keep the tool fast and simple, it uses a single effective percentage for each state based on 2026 state rate information and typical brackets instead of reproducing every state return.
Example: Someone in a state with an estimated effective rate of about 6 percent will see roughly 6 percent of their income show up as state income tax, while someone in a state with no broad income tax will see zero for state tax.
3 quick steps behind your estimate
-
Annualize your income
The calculator converts your income to an annual number. Hourly pay uses your hours per week, and biweekly, weekly, or monthly income is scaled to a full year so your effective tax rate makes sense.
-
Apply 2026 deductions and brackets
Your estimated 2026 standard deduction is subtracted, then 2026 federal tax brackets are applied to the remaining amount. This creates your estimated federal income tax and marginal bracket.
-
Add an estimated state income tax
Finally, the tool multiplies your income by an estimated effective state rate for your state. It adds that to your federal tax so you can see your combined income tax and effective tax rate for 2026.
