2027 Tax Brackets and Standard Deduction: IRS Tables
Answer first: The IRS kept the seven federal ordinary-income tax rates at 10%, 12%, 22%, 24%, 32%, 35% and 37% for tax year 2027, but raised the income thresholds. The standard deduction is $16,600 for single filers and married people filing separately, $33,200 for married couples filing jointly, and $24,925 for heads of household. These figures apply to 2027 income and generally to returns filed in 2028.
Official 2027 standard deduction amounts
| Filing status | 2027 standard deduction | Change from 2026 |
|---|---|---|
| Single | $16,600 | +$500 |
| Married filing jointly / surviving spouse | $33,200 | +$1,000 |
| Head of household | $24,925 | +$775 |
| Married filing separately | $16,600 | +$500 |
For a person who can be claimed as another taxpayer's dependent, the 2027 standard deduction generally cannot exceed the greater of $1,400 or earned income plus $500, subject to the statutory limit. The additional standard deduction for age 65 or blindness is $1,700 per qualifying condition, rising to $2,100 when the individual is unmarried and not a surviving spouse.
The standard deduction is not always the best choice. A filer may itemize when eligible mortgage interest, state and local taxes, charitable gifts and other allowable deductions exceed the standard amount. Compare using records rather than assuming homeownership automatically makes itemizing better.
2027 federal income tax brackets
The ranges below come from IRS Revenue Procedure 2026-35. Each table shows taxable income. The upper endpoint is shown in reader-friendly whole-dollar ranges; the legal calculation uses “over” and “not over” language.

How marginal brackets actually work
A bracket is not a single rate applied to every dollar. Suppose a single filer has $75,000 of taxable income in 2027. The first $12,800 is taxed at 10%, the next $39,225 is taxed at 12%, and the remaining $22,975 is taxed at 22%. That produces approximately $11,041.50 of regular federal income tax before credits, additional taxes and other special calculations.
The person's marginal rate is 22% because the last dollar falls in the 22% band. The effective rate in this simplified example is about 14.7% of taxable income. Neither percentage is automatically the rate on gross pay. Payroll withholding can also differ because it spreads an estimate across paychecks and incorporates Form W-4 information.
Why the 2027 thresholds moved—and what that means
The IRS adjusts many dollar limits for inflation each year. A higher bracket threshold does not mean Congress created a new tax rate, and it does not guarantee that every household's tax bill will fall. It means more taxable income can fit inside each existing band before the next marginal rate begins. A worker whose pay rises roughly with inflation may therefore avoid a purely inflation-driven jump into a higher band, a result sometimes described as reducing “bracket creep.”
Your year-over-year result still depends on much more than the table. A raise, bonus, capital gain, retirement distribution, filing-status change, expiring credit, larger deduction or self-employment income can outweigh the inflation adjustment. Compare 2026 and 2027 using the same household assumptions before treating the difference as tax savings. Also separate ordinary income from long-term capital gains and qualified dividends, because those categories can use different rate schedules.
Gross income, taxable income and tax due are different numbers
Gross income is the broad starting point. Adjusted gross income generally follows after eligible adjustments, and taxable income is determined after applicable deductions. Regular income tax is then calculated progressively, while credits may reduce the result and refundable credits may affect the amount paid out. Additional Medicare Tax, Net Investment Income Tax, self-employment tax and state income tax are separate calculations. This is why two people with the same salary can have different federal tax outcomes.
A refund is also not a separate bonus created by the bracket table. It is generally the difference between payments and refundable credits on one side and the final tax liability on the other. More withholding can increase a refund while reducing take-home pay during the year; less withholding can do the reverse and may create a balance due.
What else changed for 2027
The same IRS inflation release raised the maximum Child Tax Credit to $2,300 per qualifying child, with up to $1,800 potentially refundable. The maximum EITC for a taxpayer with three or more qualifying children is $8,496, and the investment-income ceiling is $12,600. Eligibility and phaseouts still depend on facts beyond these maximums.
The Alternative Minimum Tax exemption is $93,000 for unmarried individuals and $144,700 for joint filers. The annual gift-tax exclusion rises to $20,000 per recipient, while the estate-tax basic exclusion becomes $15.48 million. Those amounts address different taxes and should not be combined with the ordinary bracket table.
2027 planning checklist
- Estimate taxable income. Start with expected wages, self-employment income, interest, dividends, retirement distributions and capital gains.
- Subtract likely adjustments and deductions. Compare the standard deduction with a documented itemized estimate.
- Apply brackets progressively. Do not multiply all income by the top marginal rate reached.
- Model credits separately. Child, education, energy and other credits have their own eligibility and phaseout rules.
- Review withholding after payroll updates. Use the official IRS estimator when it reflects 2027 tables, especially after marriage, a second job, retirement or major income changes.
- Revisit quarterly payments. Self-employed taxpayers and investors should compare projected payments with applicable safe-harbor rules.
For a planning estimate, use the USFinNexus income tax calculator only after confirming its displayed tax year and assumptions. See the 2026 bracket guide for the prior-year comparison, the W-4 withholding guide for paycheck concepts, and the year-end tax checklist for records to organize.
Frequently asked questions
What is the standard deduction for 2027?
For tax year 2027, the standard deduction is $16,600 for single filers and married people filing separately, $33,200 for married couples filing jointly, and $24,925 for heads of household.
What are the federal tax rates for 2027?
The seven ordinary-income rates remain 10%, 12%, 22%, 24%, 32%, 35% and 37%. The taxable-income ranges assigned to those rates are higher for 2027.
Do the 2027 brackets apply to returns filed in 2027?
No. They generally apply to income earned from January 1 through December 31, 2027 and to federal returns normally filed in 2028.
Does entering a higher bracket tax all my income at the higher rate?
No. Federal brackets are marginal. Only the portion of taxable income inside the higher bracket is taxed at that higher rate.
Is the 2027 standard deduction the same as taxable income?
No. The standard deduction generally reduces income when taxable income is calculated. Adjustments, deductions, credits and special rules can produce a different final result.
Should I change Form W-4 now for the 2027 brackets?
Use updated 2027 payroll tables and the IRS Tax Withholding Estimator when available. Do not change withholding solely by multiplying income by a bracket rate.
