IRS 2027 tax brackets could rise 3.2%, Bloomberg projects
The federal income tax brackets could see a 3.2% increase for 2027, according to a Bloomberg Tax projection based on the latest inflation data. The adjustment, if enacted, would mark a step up from the 2.7% increase the IRS rolled out last year for the 2026 brackets.
The IRS typically announces changes that will impact how Americans file taxes each fall. The announcement for 2026 came in early October, and the agency is expected to share what the tax brackets will be for the 2027 filing season in the coming weeks.
These adjustments are meant to address “bracket creep,” which occurs when income goes up faster than the tax thresholds built into the IRS code, potentially causing a tax bill to increase even without real income growth.
Bloomberg’s report estimates that all seven tiers of the IRS’s tax brackets will see a bump in 2027:
- 10%: Single filers with taxable income of $12,800 or less; married filing jointly with $25,600 or less.
- 12%: Single filers above $12,800; married filing jointly above $25,600.
- 22%: Single filers above $52,025; married filing jointly above $104,050.
- 24%: Single filers above $109,125; married filing jointly above $218,250.
- 32%: Single filers above $208,325; married filing jointly above $416,650.
- 35%: Single filers above $264,550; married filing jointly above $529,100.
- 37%: Single filers above $661,375; married filing jointly above $793,650.
The figures are projections only. The source notes that Bloomberg Tax’s projections for 2026 were in line with the actual brackets the IRS ultimately released.
If the brackets do shift as projected, the change could mean a larger paycheck in 2027.
The tax filing deadline in 2027 is April 15.
