About Taxes Basics

Taxes Basics is a reference site for people who want to understand the U.S. federal income tax system before they sit down to file — students with a first W-2, new employees puzzling over a W-4, and anyone who has ever nodded along to the phrase "marginal tax rate" without being sure what it meant.

Every page sticks to durable, verifiable ground: definitions, how the filing process works, and where the official rules live. Wherever a page makes a factual claim about tax rules, it links the government or established nonprofit source that supports it — most often IRS Publication 17 and the IRS's own filing pages — so you never have to take this site's word for anything.

An honest note on what this site is not: these pages are reviewed reference material, not professional advice. We do not tell you what filing status to choose, what to deduct, how much to withhold, or how to handle a notice from the IRS. Tax outcomes depend on details of your situation that no general article can know. For decisions, use the IRS's official tools, the free preparation programs described in our guides, or a credentialed tax professional. For unresolved problems with the IRS itself, the independent Taxpayer Advocate Service exists specifically to help.
