The Internal Revenue Service has officially released the 2027 tax brackets, and the freshly published thresholds deliver another round of inflation relief to American households. Announced on November 5, 2026, in Revenue Procedure 2026-35, the new figures raise the standard deduction, widen every income bracket, and lift the child tax credit to $2,300 — the second consecutive year that taxpayers have benefited from the "Working Families Tax Cuts" created by the One Big Beautiful Bill Act of 2025.

The tax rates themselves have not changed. The federal system still uses seven tiers — 10%, 12%, 22%, 24%, 32%, 35%, and 37% — but the amount of income taxed at each level has moved higher. For a single filer, the 10% bracket now covers the first $12,800 of taxable income, up from $12,400 in 2026. The top 37% rate does not apply until income exceeds $661,375 for single filers and $793,650 for married couples filing jointly.

The 2027 Brackets and Standard Deduction at a Glance

The IRS re-indexes tax brackets every year to fight "bracket creep," the quiet tax hike that occurs when inflation pushes your salary into a higher tier even though your real purchasing power has barely budged. For 2027, the inflation adjustment is worth meaningful money, especially at the bottom of the income scale.

For single filers, the 10% rate applies to taxable income up to $12,800; for married couples filing jointly, that floor doubles to $25,600. At the opposite end of the spectrum, the 37% bracket now begins at $661,375 for singles and $793,650 for joint filers. Every intermediate bracket — 12%, 22%, 24%, 32%, and 35% — was also shifted upward by roughly 3.1%, matching the same inflation-adjustment formula the agency applies each year.

The standard deduction, which most households claim instead of itemizing, rises to $16,600 for single filers and $33,200 for married couples filing jointly. That is an increase of $500 and $1,000, respectively, from 2026 levels of $16,100 and $32,200. In practical terms, the higher deduction means a single filer can earn about $500 more in 2027 before paying a single dollar of federal income tax.

Families get an extra boost on the credit side. The maximum child tax credit climbs to $2,300 per qualifying child for 2027, a $100 increase from 2026, while the annual gift tax exclusion rises to $20,000.

How We Got Here: From the TCJA Sunset to Permanent Tax Cuts

The 2027 brackets would have looked very different under the old rules. The Tax Cuts and Jobs Act (TCJA) of 2017 lowered rates and doubled the standard deduction, but those individual provisions were originally set to expire after 2025. For months, tax professionals braced for a reversion to higher, pre-2017 brackets in 2026.

That scenario was averted in July 2025, when President Trump signed the One Big Beautiful Bill Act. Among other things, the law made the TCJA's individual tax cuts permanent — lower rates, a larger standard deduction, and a higher child tax credit — under the banner of the "Working Families Tax Cuts." The Tax Foundation estimated the package delivered an average tax cut of about $2,300 per household in 2026, and the IRS's own 2027 announcement is headlined with the same framing: taxpayers "continue to benefit from the Working Families Tax Cuts."

Why the 2027 Numbers Matter for Your Money

Bracket adjustments are easy to overlook, but they compound in ways that matter for savers and investors. Because the U.S. system is progressive — you pay the lowest rate on your first dollars of income and higher rates only on dollars above each threshold — a wider 10% and 12% bracket means more of your income is taxed at the cheapest possible rates.

Long-term investors get a parallel benefit on capital gains. The 0% rate on long-term capital gains and qualified dividends now applies to taxable income up to $51,050 for single filers and $102,100 for married couples filing jointly, before stepping up to 15% and then 20%. For retirees and taxable-brokerage investors who carefully manage gains, those higher 0% thresholds create more room to sell appreciated assets without triggering federal tax on the gains.

Retirement savers also gain ground. While the IRS publishes retirement plan limits separately, projections built on the same inflation data put the 2027 401(k) employee deferral limit at roughly $25,500. Combined with the higher brackets and standard deduction, the 2027 figures give households more space to defer income, realize gains, or convert assets with a lighter tax bill.

What Changed vs. 2026: The Numbers That Moved

Compared with 2026, the 2027 updates are modest but consistent — the product of a roughly 3.1% inflation adjustment:

  • Standard deduction: $16,600 single (up from $16,100) and $33,200 married filing jointly (up from $32,200).
  • Lowest bracket: 10% on income up to $12,800 single and $25,600 joint, up from $12,400 and $24,800.
  • Top bracket: 37% begins at $661,375 single and $793,650 joint, higher than 2026's thresholds.
  • Child tax credit: $2,300 per child, up $100 from $2,200.
  • 0% capital gains threshold: up to $51,050 single and $102,100 joint.
  • Gift tax exclusion: $20,000 per recipient.

What's Next: Tax Planning for 2027

Because the new brackets apply to income earned during the 2027 calendar year, the changes won't show up on your return until you file in early 2028. That leaves a full year to plan. Financial advisers generally recommend three moves when thresholds rise. First, check your withholding and estimated payments so you don't overpay all year and wait for a refund. Second, if you sit in or near the 0% capital gains band, consider harvesting long-term gains or rebalancing a taxable portfolio before year-end. Third, review whether a Roth conversion makes sense while rates remain at historically low levels.

For most households, the practical effect of the 2027 brackets is simple: a slightly larger share of income stays out of the highest marginal rates, and the standard deduction shields more of it from tax entirely. The message from Washington is equally clear — the lower individual rates are now permanent, and the brackets will keep drifting upward with inflation every year.

Key Takeaways

  • The IRS published 2027 tax brackets on November 5, 2026, in Revenue Procedure 2026-35.
  • All seven marginal rates (10% to 37%) are unchanged; every bracket's income threshold was inflation-adjusted upward by about 3.1%.
  • The standard deduction rises to $16,600 for singles and $33,200 for married couples filing jointly.
  • The child tax credit increases to $2,300 per child, and the gift tax exclusion rises to $20,000.
  • Because of the 2025 One Big Beautiful Bill Act, the lower TCJA-era rates are now permanent, so future changes should be modest inflation adjustments.
