About
Sam founded MyAfterTax to make after-tax pay estimates easier to understand. The focus is practical paycheck math — federal income tax, FICA, and state withholding — explained in plain language and tied to published rates.
Every calculator on the site is meant to share one source of truth: the same tax-year brackets and FICA figures shown on the rates pages, with links back to IRS, SSA, and state source material whenever possible.
Content and tools here are educational. They are not a substitute for personalized tax advice from a qualified professional or for official guidance from the IRS or your state department of revenue.
Focus areas
- US paycheck & take-home pay estimates
- Federal income tax brackets and standard deductions
- FICA (Social Security & Medicare) employee withholding
- State individual income tax rate structures
