Enter salary, pay frequency, filing status, and state — it breaks down federal tax, Social Security, Medicare, state tax, and 401(k)/health deductions instantly. Everything runs in your browser; nothing is sent anywhere and there's no signup.</p> <p>I also added a few things I wanted myself and couldn't find free anywhere:</p> <ul> <li>Compare two states side by side (useful if you're thinking about relocating)</li> <li>Compare two job offers after tax, not by gross salary</li> <li>See what a raise is actually worth after tax</li> </ul> <p>It's free — funded by ads, which is why I'm not asking for your email.</p> <p>Happy to take feedback on the tax math or anything that looks off. Link in the comments to respect the self-promo rules.</p> webdev opensource security ai
