Common questions
Are the 2027 standard deduction figures final?
No. The agency publishes in the autumn. Until then the 2027 column here is a projection produced by applying the statutory indexing formula — the statutory index series — to the official 2026 figures, using a +3.06% growth factor. It is labelled as a projection on every row, and this page is regenerated from the dataset the day the official figure lands.
What sets these numbers?
The 2026 figures are taken from the agency's own publication (the publishing agency, retrieved 2026-09-19).
What changed from 2026?
The table shows both years side by side so the change is readable directly. Where a row says unchanged, that is a statutory result, not an omission.
