About SimpleDeduction

SimpleDeduction exists because the 2025 tax law changed the rules for tens of millions of ordinary workers — and the official guidance is written for accountants, not people. We build free, fast calculators that answer one question at a time: what does this mean for my money?

How our calculators work

Every tool runs entirely in your browser. We use the IRS's published inflation adjustments for tax year 2026, the deduction rules from the One Big Beautiful Bill Act (tax years 2025–2028), and each state's published rates. Nothing you type is sent to our servers or stored — calculations happen on your device.

What we are not

We're not tax preparers and these tools aren't filing software. They're planning estimates to help you understand your situation before you file with a professional or reputable software. Tax law has edge cases; when the numbers matter, verify with a pro.
