2027 Federal Income Tax Brackets (Projected): Rates and Standard Deduction

The projected 2027 federal income-tax brackets show how ordinary taxable income may be taxed at different marginal rates, from 10% to 37%. The projections also indicate higher income thresholds and standard deductions for 2027.

Important: These figures are projections from Wolters Kluwer, not final IRS amounts. As of October 14, 2026, the IRS's inflation-adjustment page lists the official 2026 adjustments but not the 2027 individual tax brackets. Confirm the final figures against IRS guidance when it becomes available.

Key Takeaways

• The projected 2027 federal income-tax rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%.

• The projected income thresholds vary by filing status: Single, Married Filing Jointly, Married Filing Separately, and Head of Household.

• The projected 2027 standard deduction is $16,600 for Single and Married Filing Separately taxpayers, $33,200 for Married Filing Jointly taxpayers and qualifying surviving spouses, and $24,950 for Head of Household taxpayers.

• Federal income-tax brackets apply to taxable income, not directly to gross salary.

• Wolters Kluwer used an 11-month CPI average because October 2025 CPI data were not released during the federal government shutdown. Final IRS amounts may differ.

• Tax year 2027 income is generally reported on a tax return filed in 2028.

What Are the Projected 2027 Federal Income-Tax Brackets?

Federal income-tax brackets are income ranges taxed at different marginal rates. The rate that applies to your next dollar of taxable income may be higher than the rates applied to earlier portions of your income.

The following thresholds are Wolters Kluwer's projections for tax year 2027. The ranges are presented using “over” and “up to” language to avoid overlapping bracket boundaries.

What Is the Projected 2027 Standard Deduction?

The standard deduction reduces the amount of income subject to federal income tax. The projected 2027 amounts depend on filing status.

These amounts are projections, not confirmed IRS figures. Taxpayers who itemize deductions should compare their eligible itemized deductions with the standard deduction and follow the rules that apply to their circumstances.

The standard deduction does not reduce tax dollar for dollar. It generally reduces taxable income before the applicable income-tax rates are applied.

How Do Federal Marginal Tax Rates Work?

A marginal tax rate applies only to the portion of taxable income within its bracket. Reaching a higher bracket does not mean that all your taxable income is taxed at the highest rate you reach.

For example, consider a Single taxpayer with $100,000 of taxable income under the projected 2027 brackets:

The example produces a simplified federal income-tax amount of $16,541.50, before tax credits and other applicable adjustments or taxes. It assumes the projected thresholds and ordinary income-tax rates apply to the full amount shown.

The taxpayer's effective rate in this example is approximately 16.54% of taxable income, even though the highest marginal rate reached is 22%.

How Do the Projected 2027 Brackets Compare With 2026?

Wolters Kluwer's projections show higher bracket thresholds for 2027 than the 2026 thresholds. Here is a comparison for Married Filing Jointly taxpayers.

For a detailed explanation of the current tax-year thresholds, deductions, and other provisions, see our 2026 Federal Income Tax Brackets guide.

The higher projected thresholds may affect how much taxable income falls into each bracket. However, a higher threshold does not automatically mean every taxpayer will owe less tax. The final outcome depends on taxable income, deductions, credits, filing status, and other applicable tax rules.

For reference, the IRS's official 2026 standard deductions are $16,100 for Single and Married Filing Separately taxpayers, $32,200 for Married Filing Jointly taxpayers, and $24,150 for Head of Household taxpayers. The projected 2027 figures above should not be treated as official until confirmed by the IRS.

Why Are the 2027 Tax Brackets Still Projections?

Federal tax brackets and certain deductions are adjusted annually using inflation-related calculations specified by law.

Wolters Kluwer explains that the federal government shutdown in 2025 meant the Bureau of Labor Statistics did not release October 2025 CPI data. Its 2027 projections therefore use an 11-month average covering September 2025 through August 2026 rather than a complete 12-month average.

The publication notes that it is unclear how the IRS will handle the missing month. Consequently, the official inflation-adjusted figures may differ from these estimates.

The distinction matters: a third-party projection can support preliminary planning, but it is not a substitute for an IRS announcement or applicable tax guidance.

Other Projected Federal Tax Adjustments for 2027

Wolters Kluwer also identifies the following projected amounts for tax year 2027:

These figures are also projections and are subject to the applicable statutory rules and final official guidance. The Section 179 amounts may be relevant to eligible business taxpayers; the estate-tax figures apply to a different set of tax considerations than ordinary income-tax brackets.

How Should You Prepare for Tax Year 2027?

You can use projected tax brackets as an initial planning reference, but avoid making a major tax decision based solely on estimates.

1. Estimate taxable income. Start with expected income and account for deductions and adjustments that may apply.

2. Confirm your filing status. Filing status affects both the applicable bracket thresholds and the standard deduction.

3. Review withholding and estimated payments. Compare projected tax liability with expected withholding and payments. If you make quarterly payments, review our guide to estimated taxes for general payment guidance.

4. Evaluate deductions and credits. Eligibility and the value of deductions or credits depend on the applicable rules and your individual circumstances. Learn more in our guide to tax credits vs. tax deductions.

5. Recheck the official figures. Update your calculations when the IRS releases the final 2027 inflation adjustments.

For more accurate planning, use the projected brackets as a preliminary estimate and confirm the applicable tax rules before filing or changing your payment strategy.

Conclusion

The projected 2027 federal income-tax brackets and standard deductions provide an early reference for estimating future federal income tax. The projections indicate higher thresholds than in 2026, but the final IRS amounts may differ because of the missing October 2025 CPI data.

Use these estimates for preliminary planning, verify the final IRS guidance before relying on the figures, and consider your filing status, deductions, credits, and total tax situation when estimating your liability.
