Common questions
What is the 2027 standard deduction for married filing jointly?
$33,150 (projected until the agency announces it), up from $32,200 in 2026.
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.
When will the official 2027 standard deduction be announced?
The IRS publishes the official 2027 standard deduction in its annual inflation-adjustment revenue procedure. The 2026 figures came in Rev. Proc. 2025-32, released on October 9, 2025 (IRS news release IR-2025-103). Until then, the 2027 figures on this page are our projection; the published figures replace them here.
What sets these numbers?
The 2026 figures are taken from the agency's own publication (IRS Rev. Proc. 2025-32, 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.
