2027 Tax Brackets for Single (Projected)

Projected, not yet official: single filers keep the seven rates from 10% through 37% in 2027, with the 10% band ending at $12,775 and the 37% rate starting above $660,550 of taxable income. The projected standard deduction is $16,600, up from $16,100 in 2026.

No. The IRS sets 2027 thresholds in its annual inflation-adjustment revenue procedure, usually published in October or November (the 2026 figures came from Rev. Proc. 2025-32). Until then this page runs the statutory formula in IRC § 1(f) and § 1(j) on published BLS chained CPI-U data through August 2026, about 3.06% above the 2026 adjustment. The page switches to the IRS figures the day they are published.

$16,600, against a confirmed $16,100 for 2026. Each qualifying condition — 65 or older, or blind — is projected to add $2,100 ($2,050 in 2026). OBBBA's separate senior deduction of up to $6,000 per person aged 65 or older still applies in 2027; it is fixed by statute, not indexed, and phases out above $75,000 of modified AGI.

BLS never published the October 2025 index, and no agency has said how the twelve-month average should treat the gap. This page fills it with the midpoint of September and November. Leaving October out instead would raise 6 of the thresholds for single filers by $25 to $825, for example the top of the 10% band to $12,800 instead of $12,775. The IRS revenue procedure settles it.

Usually a little, if your income does not rise. Every bracket ceiling and the standard deduction move up with inflation, so more of the same income is taxed at the lower rates. The rates themselves do not change: OBBBA made the 10/12/22/24/32/35/37% schedule permanent.
