Tax Year 2025

What changed on your taxes this year?

Your actual return

Every year the IRS adjusts dozens of dollar amounts for inflation — standard deductions, tax brackets, credit phase-outs, retirement contribution limits — and sometimes Congress changes the rules outright. Most of those changes never make headlines, but they can move your refund or your bill by hundreds of dollars. This page is generated directly from AsasifyTax's own tax-year parameter files, comparing this year's figures against last year's, line by line. It updates automatically whenever either year's numbers change — nobody writes this list by hand.
