Figures are for tax year 2026. This Guide lists what is different on a 2026 federal return and what to do about it. It covers the One Big Beautiful Bill Act, Public Law 119-21, approved on 4 July 2025 ([text on govinfo.gov](https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm)), and the 2026 inflation figures in [Rev. Proc. 2025-32](https://www.irs.gov/pub/irs-drop/rp-25-32.pdf). It is federal only. States decide for themselves whether to follow these rules. Many of the new deductions are temporary: each rule below names the years it covers.
