Methodology

How these calculators work

01

Published IRS rates

We use 2025 IRS Publication 15-T withholding tables and the official federal income tax brackets effective January 1, 2025.

02

State DOR sources

Each state calculator references that state's Department of Revenue published withholding schedules and income tax brackets.

03

Transparent math

We show pre-tax deductions, FICA, federal, and state separately so you understand every line item — no black-box math.

04

Always a disclaimer

Tax law changes. Individual situations differ. We always point you to the primary source and recommend a CPA review.
