Millions of American taxpayers will benefit from increased standard deductions and adjustments to tax brackets for the 2027 tax year, as announced by the Internal Revenue Service (IRS) on November 5. The changes will affect nearly 70 tax provisions, with new amounts applicable to income earned in 2027, and will be reflected in tax returns filed in 2028.
IRS Adjusts Standard Deductions and Tax Brackets
The IRS revealed that the lowest marginal tax rate will remain at 10 percent, applicable to earnings up to USD 12,800 for single filers and USD 25,600 for married couples filing jointly. The remaining tax rates will range from 12 percent to 35 percent, while the top rate of 37 percent will apply to individual filers earning over USD 661,375 and joint filers exceeding USD 793,650.
For 2027, the standard deduction for married couples filing jointly will increase by USD 1,000 to USD 33,200. Single filers and married individuals filing separately will qualify for a deduction of USD 16,600, while heads of households will see a deduction of USD 24,925.
IRS Chief Executive Officer Frank J. Bisignano stated, “Hardworking American taxpayers will continue to benefit from the Working Families Tax Cuts (WFTC) and will see WFTC credits and deductions increase with this adjustment.”
Child Tax Credit and Other Adjustments
The maximum child tax credit will rise to USD 2,300 per qualifying child, reflecting a USD 100 increase from the previous year. Up to USD 1,800 of this credit will be refundable, allowing eligible families to receive part of the credit even if they owe little or no federal tax.
Additionally, the maximum Earned Income Tax Credit for low-to-moderate-income workers with three or more qualifying children will increase to USD 8,496, up from USD 8,231 in 2026. Families adopting children can claim expense credits up to USD 18,250, with a refundable limit of USD 5,280.
Businesses will also benefit from increased expensing limits, allowing up to USD 2,640,000 for section 179 property. The cap for sport utility vehicles is set at USD 33,100.
Background on IRS Tax Provisions
The IRS regularly adjusts tax provisions to account for inflation, ensuring that taxpayers are not pushed into higher tax brackets solely due to inflationary wage increases. These adjustments are part of the broader Working Families Tax Cuts initiative, which aims to provide tax relief to families and individuals.
While the IRS has made significant adjustments, it has not provided inflation adjustments for personal exemptions, which remain at zero under current provisions. The agency also maintained the removal of overall itemized deduction limitations for most filers, capping them only for top-bracket taxpayers.
