The new inflation adjustments will affect tax returns filed in 2028, with changes to income tax brackets, family tax benefits, business deductions and several other provisions.
The Internal Revenue Service (IRS) has announced its annual inflation adjustments for the 2027 tax year, updating nearly 70 tax provisions, including federal income tax brackets, standard deductions, the Child Tax Credit and business expense limits.
The adjustments are designed to account for inflation and will generally apply to tax returns filed in 2028.
According to the IRS, American taxpayers and businesses will see several increases in available deductions and credits under the Working Families Tax Cuts (WFTC).
“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,” said IRS Chief Executive Officer Frank J. Bisignano. He highlighted higher standard deductions, an increased Child Tax Credit and expanded tax benefits for businesses.
Higher standard deductions in 2027
One of the most important changes for individual taxpayers is the increase in the standard deduction.
For the 2027 tax year, the standard deduction will be:
- Married couples filing jointly: $33,200, up $1,000 from 2026.
- Single taxpayers and married individuals filing separately: $16,600.
- Heads of households: $24,925.
The IRS has also adjusted the federal income tax brackets for inflation. The top marginal tax rate remains 37%, applying to single taxpayers with taxable income above $661,375 and married couples filing jointly with income above $793,650.
The other marginal tax rates and income thresholds for 2027 are:
| Tax rate | Single filers | Married filing jointly |
|---|---|---|
| 37% | Over $661,375 | Over $793,650 |
| 35% | Over $264,550 | Over $529,100 |
| 32% | Over $208,325 | Over $416,650 |
| 24% | Over $109,125 | Over $218,250 |
| 22% | Over $52,025 | Over $104,050 |
| 12% | Over $12,800 | Over $25,600 |
| 10% | $12,800 or less | $25,600 or less |
These are marginal tax rates, meaning the applicable rate applies only to the portion of taxable income within each bracket, not to a taxpayer’s entire income.
Child Tax Credit increases to $2,300
Families will also benefit from an increase in the Child Tax Credit.
For 2027, the maximum credit rises to $2,300 per qualifying child, an increase of $100 from 2026. The refundable portion of the credit increases to $1,800, also up $100.
The Alternative Minimum Tax (AMT) exemption amounts will also increase. For unmarried individuals, the exemption will be $93,000, with the phaseout beginning at $515,950. For married couples filing jointly, the exemption rises to $144,700, with the phaseout starting at $1,031,900.
Higher estate and gift tax exemptions
The IRS has increased the federal estate tax exclusion for 2027 to $15.48 million, up from $15 million in 2026.
The annual gift tax exclusion will rise from $19,000 to $20,000 per recipient. This means individuals can give up to that amount to each person during the calendar year without the gift counting toward their lifetime gift and estate tax exemption.
For gifts to a spouse who is not a U.S. citizen, the annual exclusion increases to $201,000, compared with $194,000 in 2026.
More tax benefits for businesses and families
Business owners will also see higher limits under Section 179, which allows qualifying businesses to deduct the cost of certain equipment and property.
For tax year 2027, the maximum amount businesses can expense increases to $2.64 million, up from $2.56 million in 2026. The deduction limit for sport utility vehicles rises to $33,100, compared with $32,000.
The maximum employer-provided childcare tax credit also increases. For 2027, the limit rises to $515,943.67, compared with $500,000 in 2026. Eligible small businesses may qualify for a higher maximum of $619,132.40.
The maximum adoption credit increases to $18,250 in 2027, up from $17,670. The refundable portion of the credit rises to $5,280.
Other important tax adjustments
Several additional provisions will be adjusted for inflation in 2027:
- Earned Income Tax Credit: The maximum credit for qualifying taxpayers with three or more children increases to $8,496, compared with $8,231 in 2026.
- Transportation and parking benefits: The monthly limit for qualified transportation fringe benefits and qualified parking increases to $350.
- Health Flexible Spending Accounts: The contribution limit rises to $3,500, up $100. The maximum carryover of unused funds increases to $700 for plans that allow it.
- Medical Savings Accounts: For self-only coverage, the minimum annual deductible increases to $3,000 and the maximum to $4,550. The out-of-pocket limit rises to $6,050. For family coverage, the deductible range will be $6,050 to $9,050, with an out-of-pocket limit of $11,050.
- Foreign Earned Income Exclusion: The amount increases to $137,300, up from $132,900 in 2026.
Some tax provisions will remain unchanged
Not every tax provision will increase with inflation.
The personal exemption remains at zero for 2027, following its elimination under the 2017 Tax Cuts and Jobs Act and its subsequent permanence under the Working Families Tax Cuts.
The limitation on itemized deductions also remains eliminated for most taxpayers, although a restriction on the tax benefit of itemized deductions applies to individuals in the highest, 37% tax bracket.
The income thresholds for the Lifetime Learning Credit will also remain unchanged. The credit phases out for taxpayers with modified adjusted gross income between $80,000 and $90,000, or between $160,000 and $180,000 for married couples filing jointly.
The IRS published the adjustments in Revenue Procedure 2026-35, which provides the detailed figures for nearly 70 tax provisions.
The new figures apply to the 2027 tax year, meaning most taxpayers will use them when preparing and filing their federal income tax returns in 2028.
