About PlainTaxData

PlainTaxData provides federal income tax reference data in a clean, ad-light format. Tax brackets, standard deductions, filing deadlines, and a free estimator — all sourced directly from IRS publications.

Our Mission

Tax information should be free, accessible, and easy to understand. Most tax websites bury the numbers you need behind sign-up walls, upsells, and confusing interfaces. We present the data plainly — no account required, no AI-generated filler, no hidden agendas.

Data Sources

All data on this site comes from official IRS sources:

  • Tax brackets: IRS Revenue Procedures (annual inflation adjustments)
  • Standard deductions: IRS Publication 501
  • Capital gains rates: IRS Revenue Procedures + Publication 550
  • Contribution limits: IRS annual announcements (IR-2024-285, etc.)
  • Credits (EITC, CTC): IRS Publications 596 and 972

Important Disclaimer

PlainTaxData is an informational resource, not a tax advisory service. The content on this site does not constitute tax, legal, or financial advice. Tax situations are individual — consult a qualified tax professional (CPA, EA, or tax attorney) for advice specific to your circumstances.

While we strive for accuracy, tax law changes frequently. Always verify information against current IRS publications before making tax decisions.
