The Internal Revenue Service (IRS) on Thursday unveiled the annual inflation adjustments for nearly 70 tax provisions for the 2027 tax year. These adjustments, detailed in Revenue Procedure 2026-35, significantly impact critical components of the U.S. tax code, including marginal tax rates, the standard deduction, and the earned income tax credit. The release comes as the provisions of the "One Big Beautiful Bill Act" (OBBBA), recently rebranded by Republicans as the "Working Families Tax Cuts" (WFTC), continue to shape the tax landscape for American individuals and businesses.
IRS CEO Frank Bisignano commented on the significance of these adjustments, stating, "Taxpayers will continue to benefit from tax provisions in the One Big Beautiful Bill Act, the signature tax-and-spending law signed by President Donald Trump in July 2025." He further elaborated in a statement released on November 5th, "We will see WFTC credits and deductions increase with this adjustment. American individuals and businesses will see increased tax benefits next tax year ranging from an increase in the standard deduction and the Child Tax Credit for families, and a boost to the amount that can be expensed by businesses."
The "One Big Beautiful Bill Act," enacted in the summer of 2025, represented a sweeping overhaul of the nation’s tax and spending policies. Its proponents argued it would stimulate economic growth and provide much-needed relief to middle- and lower-income families. The rebranding to "Working Families Tax Cuts" underscores a strategic effort to highlight the legislation’s intended benefits for a broad segment of the population. The annual inflation adjustments are a mechanism designed to prevent "bracket creep," where inflation erodes the value of tax deductions and credits, effectively pushing taxpayers into higher tax brackets without an increase in their real income.
Key Tax Year 2027 Adjustments
The IRS’s Revenue Procedure 2026-35 provides a comprehensive overview of the inflation-adjusted figures, which generally apply to tax returns filed in 2028.
Standard Deduction
The standard deduction, a crucial element for many taxpayers who choose not to itemize deductions, has seen a notable increase for the 2027 tax year. For married couples filing jointly, the standard deduction will rise to $33,200, an increase of $1,000 compared to the 2026 tax year. Single taxpayers and married individuals filing separately will benefit from a standard deduction of $16,600, an increase of $500. Heads of households will see their standard deduction increase to $24,925. These adjustments are designed to ensure that the value of the standard deduction keeps pace with the rising cost of living.
Marginal Tax Rates
The marginal tax rate structure, which dictates the percentage of tax paid on each additional dollar of income, also reflects inflation adjustments. For the 2027 tax year, the top individual income tax rate remains at 37%. This rate applies to single taxpayers with taxable incomes exceeding $661,375 and married couples filing jointly with incomes above $793,650. The IRS revenue procedure details the adjusted thresholds for all income brackets, ensuring that taxpayers are not pushed into higher tax brackets solely due to inflation. The lowest marginal tax rate remains 10%, applicable to single individuals with incomes of $12,800 or less and married couples filing jointly with incomes of $25,600 or less. These adjustments are critical for maintaining the progressive nature of the tax system and providing relief to lower-income earners.
Child Tax Credit
The Child Tax Credit (CTC), a cornerstone of the WFTC legislation aimed at supporting families with children, has also been adjusted for inflation. The maximum Child Tax Credit for 2027 is set at $2,300 per qualifying child, an increase of $100 from the previous year. Furthermore, the refundable portion of the CTC, which can be received as a refund even if no tax is owed, has also increased by $100 to $1,800 for the 2027 tax year. This enhancement aims to provide greater financial assistance to families with lower tax liabilities.
Alternative Minimum Tax Exemption Amounts
The Alternative Minimum Tax (AMT) is a parallel tax system designed to ensure that high-income earners pay at least a minimum amount of tax. The exemption amounts for the AMT have been adjusted to reflect inflation. For tax year 2027, unmarried individuals will have an AMT exemption amount of $93,000, phasing out at $515,950. For married couples filing jointly, the exemption amount rises to $144,700, with the phase-out beginning at $1,031,900. These adjustments are intended to shield more middle-income taxpayers from the AMT.
Estate Tax Exclusion
The estate tax, levied on the transfer of a deceased person’s assets, is subject to an annual exclusion amount. For estates of decedents who pass away during 2027, the basic exclusion amount is $15,480,000, an increase from the $15,000,000 exclusion for 2026. This significant exclusion amount means that a substantial portion of estates will not be subject to federal estate tax.
Annual Exclusion for Gifts
The annual exclusion for gifts, which allows individuals to give a certain amount of money or assets to another person each year without incurring gift tax, has also been indexed for inflation. For calendar year 2027, this exclusion increases to $20,000 per recipient, up from $19,000 in 2026. This adjustment provides greater flexibility for individuals to transfer wealth during their lifetime. The annual exclusion for gifts made to a non-U.S. citizen spouse has also seen a substantial increase, rising to $201,000 for 2027, up from $194,000 in 2026.
Expensing
Businesses can often deduct the cost of qualifying assets in the year they are placed in service, a provision known as expensing. For tax year 2027, taxpayers can expense up to $2,640,000 of Section 179 property, an increase from $2,560,000 in 2026. Additionally, the limit for expensing sport utility vehicles in 2027 is $33,100, up from $32,000 in the prior year. These increases are designed to incentivize business investment and encourage capital spending.
Adoption Credits
The financial support for individuals and families pursuing adoption has also been enhanced through inflation adjustments. The maximum credit allowed for adoptions in tax year 2027 is the amount of qualified adoption expenses up to $18,250, an increase from $17,670 in 2026. The refundable portion of the adoption credit for 2027 is $5,280.
Employer-Provided Childcare Tax Credit
To encourage employers to support their employees’ childcare needs, the employer-provided childcare tax credit has been adjusted. For tax year 2027, the maximum amount of this credit rises to $515,943.67, an increase from $500,000 in 2026. For eligible small businesses, this amount is further enhanced to $619,132.40.
Other Notable Items Affected by Indexing
Beyond the major provisions, several other tax-related amounts are subject to annual inflation adjustments.
Earned Income Tax Credits
The Earned Income Tax Credit (EITC), a refundable tax credit for low- to moderate-income working individuals and couples, has seen its maximum amounts increased. For tax year 2027, the maximum EITC is $8,496 for qualifying taxpayers with three or more qualifying children, up from $8,231 in 2026. Revenue Procedure 2026-35 provides a detailed table outlining the maximum EITC amounts for other categories, as well as income thresholds and phase-out rules.
Qualified Transportation Fringe Benefit
The monthly limitations for qualified transportation fringe benefits, including commuter transportation and qualified parking, have been adjusted. For tax year 2027, these monthly limitations increase to $350, a $10 rise from 2026.
Health Flexible Spending Cafeteria Plans
For tax years beginning in 2027, the dollar limitation for voluntary employee salary reductions for contributions to health flexible spending arrangements (FSAs) increases to $3,500, a $100 increment from the previous year. For cafeteria plans that allow the carryover of unused amounts, the maximum carryover amount has been set at $700, an increase of $20 from 2026.
Medical Savings Accounts
Participants in Medical Savings Accounts (MSAs) will see adjusted deductible and out-of-pocket expense limits for 2027. For self-only coverage, the annual deductible must be at least $3,000 (up $100 from 2026) and not more than $4,550 (up $150). The maximum out-of-pocket expense for self-only coverage is $6,050, an increase of $200. For family coverage, the annual deductible must be at least $6,050 (up from $5,850) and not more than $9,050 (up $300). The out-of-pocket expense limit for family coverage is $11,050 for tax year 2027, an increase of $250.
Foreign Earned Income Exclusion
U.S. citizens and resident aliens working abroad may exclude a certain amount of their foreign earnings from U.S. taxation. For tax year 2027, this foreign earned income exclusion is $137,300, an increase from $132,900 for tax year 2026.
Items Unaffected by Indexing
It is important to note that certain tax provisions, by statutory design, are not subject to annual inflation adjustments. These items, which may have been indexed in the past, are now fixed by law and will not change due to inflation unless new legislation is enacted.
The IRS’s annual release of inflation adjustments serves as a critical reminder of the dynamic nature of tax law and its direct impact on the financial planning of millions of Americans. The adjustments, particularly in the context of the recently enacted "Working Families Tax Cuts" legislation, aim to maintain the intended benefits of these tax provisions and provide a degree of predictability for taxpayers.
