2027 tax brackets are set to bring higher income thresholds and larger standard deductions for millions of American taxpayers. The Internal Revenue Service announced the inflation-adjusted figures Thursday, with the changes applying to income earned during tax year 2027 and returns generally filed in 2028.
The IRS also adjusted several other federal tax provisions, including long-term capital gains brackets, the estate and gift tax exemption, and eligibility rules for the earned income tax credit. The updates arrive as households continue to face elevated costs for housing, groceries, gasoline and other everyday expenses.
Key 2027 Tax Brackets Revealed by the IRS
The federal income tax system remains progressive. That means taxpayers do not pay one single rate on all of their earnings. Instead, different portions of taxable income are taxed at different rates.
For 2027, the seven federal income tax rates will range from 10% to 37%. The highest rate will apply to taxable income above $661,375 for single taxpayers and above $793,650 for married couples filing jointly.
- 37%: Taxable income above $661,375 for individuals and $793,650 for joint filers
- 35%: Taxable income above $264,550 for individuals and $529,100 for joint filers
- 32%: Taxable income above $208,325 for individuals and $416,650 for joint filers
- 24%: Taxable income above $109,125 for individuals and $218,250 for joint filers
- 22%: Taxable income above $52,025 for individuals and $104,050 for joint filers
- 12%: Taxable income above $12,800 for individuals and $25,600 for joint filers
- 10%: Taxable income of $12,800 or less for individuals and $25,600 or less for joint filers
These thresholds are based on taxable income, not necessarily total salary or gross earnings. Taxable income is generally calculated after subtracting eligible deductions from adjusted gross income.
Standard Deduction Will Increase in 2027
One of the most important changes for households is a higher standard deduction. Married couples filing jointly will be able to claim $33,200 in 2027, up from $32,200 in 2026.
Single taxpayers will receive a standard deduction of $16,600, compared with $16,100 in 2026. The increase may reduce taxable income for people who do not itemize deductions on their federal returns.
Taxpayers typically compare the standard deduction with their itemized deductions and use whichever provides the larger tax benefit. Itemized deductions can include certain eligible medical expenses, state and local taxes, mortgage interest and charitable contributions, depending on applicable rules.
Why Inflation Adjustments Matter
The IRS adjusts tax brackets and several tax benefits each year using inflation data. The goal is to prevent taxpayers from being pushed into higher tax brackets solely because wages and prices have increased.
However, the size of the adjustment does not automatically mean every household will pay less in taxes. A taxpayer’s final bill depends on income, deductions, credits, investment gains, filing status and withholding throughout the year.
The latest announcement comes after the consumer price index rose 3.7% in September 2026 from a year earlier, according to the Bureau of Labor Statistics. That was higher than the 3.4% annual increase recorded in August.
Other Tax Changes to Watch
Beyond ordinary income tax brackets, the IRS increased figures for long-term capital gains brackets. Those thresholds are particularly relevant to investors who sell stocks, mutual funds, real estate or other assets held for more than one year.
The agency also announced adjustments to the estate and gift tax exemption. Wealthier households and people involved in significant lifetime gifts or estate planning may need to review how the new limits affect their strategies.
Eligibility figures for the earned income tax credit were also updated. The credit can provide valuable support to qualifying workers and families, although eligibility depends on income, filing status, number of qualifying children and other requirements.
How Taxpayers Can Prepare for 2027
Workers may want to review their withholding after the new figures take effect. A change in income, a new job, marriage, retirement or a major investment transaction can all affect the amount owed at tax time.
- Review your expected 2027 income and filing status.
- Compare the standard deduction with potential itemized deductions.
- Check whether retirement contributions could reduce taxable income.
- Consider the tax impact of selling investments or exercising stock options.
- Revisit withholding if your household income or deductions change.
The 2027 tax brackets provide useful planning information well before tax returns are due. Still, taxpayers should remember that federal tax rules can change if Congress passes new legislation. For complicated situations, a certified public accountant, enrolled agent or qualified financial adviser can help interpret the rules.
