Source, and how our projection compared
The 2027 bands are from IRS Rev. Proc. 2026-35, released November 5, 2026. Before that release this page projected them by multiplying each 2018 threshold in IRC § 1(j)(2) by the § 1(f)(3) cost-of-living ratio from BLS chained CPI-U. Computed with the never-published October 2025 index left out of the average, that formula gives every official 2027 threshold; the projection had interpolated October instead and ran slightly low.

Frequently asked questions
What are the 2027 tax brackets for single filers?
Under IRS Rev. Proc. 2026-35, single filers keep the seven rates from 10% through 37% in 2027, with the 10% band ending at $12,800 and the 37% rate starting above $661,375 of taxable income. The standard deduction is $16,600, up from $16,100 in 2026.
Are these 2027 brackets for single filers official?
Yes. They are the IRS figures from Rev. Proc. 2026-35, the annual inflation-adjustment revenue procedure, released November 5, 2026 (the 2026 figures came from Rev. Proc. 2025-32). They apply to income earned in tax year 2027, reported on returns filed in 2028.
What is the 2027 standard deduction for single filers?
$16,600, against $16,100 for 2026. Each qualifying condition — 65 or older, or blind — adds $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.
Will I pay less tax in 2027 on the same income as single?
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.
