The IRS has not yet announced the 2027 tax brackets or the 2027 standard deduction. As of November 1, 2026, the official numbers are still the 2026 ones: a $16,100 standard deduction for single filers and $32,200 for married couples filing jointly. Last year the IRS published the next year's numbers on October 9, so the 2027 release could come any day. Any 2027 figure you see before then is an estimate.
Key takeaways
- The IRS's October 2026 news releases include no 2027 inflation adjustments, so the 2026 brackets and standard deduction are still the latest official numbers.
- The 2026 standard deduction is $16,100 single, $32,200 married filing jointly and $24,150 head of household, up about 2.2% from 2025.
- Your 2026 tax return, filed in early 2027, uses the 2026 numbers. The 2027 numbers apply to income you earn in 2027.
- By law the brackets are adjusted each year using the chained CPI, a government inflation measure, averaged over the 12 months ending August 31.
- The seven tax rates (10% to 37%) stay the same. Inflation adjustments move the income ranges and the standard deduction.
If you are trying to plan your 2027 taxes, you may have noticed that every site shows slightly different numbers. That is because the real ones are not out yet. The IRS updates the tax brackets and the standard deduction every year for inflation, and the 2027 update has not been published.
This post shows what is official today, why the numbers change each year, and how to plan without guessing. We will cover the IRS announcement when it arrives.
Has the IRS announced the 2027 tax brackets?
No. The IRS’s list of October 2026 news releases covers topics such as identity theft protection, retirement plan corrections and the adoption credit. It does not include the 2027 inflation adjustments.
The IRS published last year’s update on October 9, 2025, in release IR-2025-103. The 2027 release is later than that this year. We do not know when it will land, so we are not guessing a date.
You may see articles with 2027 “projected” brackets. Those are forecasts from outside firms. They are not IRS numbers, and the real ones can differ by dollars that matter at a bracket edge.
What are the official numbers right now?
These are the 2026 federal income tax brackets from the IRS. Each rate applies only to the slice of your taxable income (income after deductions) that falls in that range.
| Rate | Single: starts at | Married filing jointly: starts at |
|---|---|---|
| 10% | $0 | $0 |
| 12% | $12,400 | $24,800 |
| 22% | $50,400 | $100,800 |
| 24% | $105,700 | $211,400 |
| 32% | $201,775 | $403,550 |
| 35% | $256,225 | $512,450 |
| 37% | $640,600 | $768,700 |
The same IRS release gives the standard deduction, which is the amount you can subtract from your income without listing individual deductions:
| Filing status | 2025 | 2026 | Change |
|---|---|---|---|
| Single or married filing separately | $15,750 | $16,100 | +$350 (2.2%) |
| Married filing jointly | $31,500 | $32,200 | +$700 (2.2%) |
| Head of household | $23,625 | $24,150 | +$525 (2.2%) |
The percentage column is our own math: $350 ÷ $15,750 = 2.2%, and the other two rows come out the same.
Why do the brackets change every year?
Prices go up over time. Without a fix, a raise that only keeps up with inflation could push you into a higher bracket even though you are no better off. This is sometimes called “bracket creep.”
To prevent it, federal law (26 U.S.C. § 1(f)) tells the IRS to raise the bracket ranges each year using the chained CPI. That is an inflation measure the Bureau of Labor Statistics publishes. The law uses its average over the 12 months ending August 31.
The IRS then publishes the new dollar amounts. The rates themselves do not change, so the 12% rate is still 12%. The ranges move up, and so does the standard deduction.
Which numbers apply to my taxes?
It depends on which return you mean:
- Income you earned in 2026: you report it when you file in early 2027. The IRS says its 2026 adjustments generally apply to returns filed in 2027, so you use the 2026 numbers in the tables above.
- Income you earn in 2027: you report it in 2028 and use the 2027 numbers, once they are official.
So nothing about the 2027 announcement changes the return you are about to prepare. It matters for planning ahead, such as setting your 2027 paycheck withholding or deciding how much to save.
How much does a bigger standard deduction save?
Here is an illustration with made-up income, using the official 2026 numbers. Say you are a single filer earning $76,100 in wages with no other income and you take the standard deduction.
- Taxable income: $76,100 − $16,100 = $60,000.
- First $12,400 at 10%: $1,240.
- Next $38,000 (from $12,400 to $50,400) at 12%: $4,560.
- The last $9,600 (from $50,400 to $60,000) at 22%: $2,112.
- Total federal income tax: $1,240 + $4,560 + $2,112 = $7,912.
Your top bracket is 22%, so every extra dollar of deduction saves you 22 cents. If a standard deduction rose by $500, you would save about $500 × 0.22 = $110. That is a simple illustration of how the yearly bump works. It is not a prediction of the 2027 amount, and it ignores credits and other taxes.
Remember that a deduction is not the same as a credit. A deduction lowers the income you are taxed on. A credit lowers the tax itself, dollar for dollar.
What to do now
- Use the 2026 numbers for your 2026 return. Do not wait for the 2027 announcement to get ready to file.
- Check your withholding. Look at your latest pay stub and see how much federal tax is coming out. Our paycheck calculator shows what a given salary leaves after tax.
- Estimate your 2026 tax bill. Plug your income into the income tax calculator and compare it with what you have paid so far this year.
- Treat 2027 numbers as unofficial until the IRS publishes them. Our 2027 tax brackets page is labeled as a projection and will be updated when the IRS announces the real figures.
- Look at the full 2026 tables. See our 2026 tax brackets page for every filing status.
- Check the IRS newsroom again in the coming weeks. Look for the release on 2027 inflation adjustments, then update your plan.
- Think about a raise or a job change. The salary calculator helps you see what a different pay level means after taxes.
This is general information, not personal tax advice. Your own situation, credits and state taxes can change what you owe.
Frequently asked questions
When will the IRS announce the 2027 tax brackets?
The IRS has not given a date. Last year it published the 2026 numbers on October 9, 2025, in release IR-2025-103. The IRS newsroom showed no 2027 inflation adjustments among its October 2026 releases, so the announcement is still pending. Check the IRS newsroom for a release titled 'tax inflation adjustments for tax year 2027.'
What is the standard deduction for 2027?
The IRS has not announced it. The latest official amounts are for 2026: $16,100 for single filers and married people filing separately, $32,200 for married couples filing jointly, and $24,150 for heads of household. Estimates for 2027 come from outside firms and are not IRS numbers. Wait for the IRS release before using a 2027 figure in any plan.
Will the 2027 tax rates change?
The IRS inflation adjustment does not change the rates themselves. The seven rates in the 2026 table are 10%, 12%, 22%, 24%, 32%, 35% and 37%. What the adjustment changes is the income ranges where each rate applies, and the size of the standard deduction. Changing the rates would take a new law from Congress.
Which tax numbers do I use when I file in 2027?
When you file in early 2027, you report income you earned in 2026, so you use the 2026 brackets and the 2026 standard deduction. The IRS says its 2026 adjustments generally apply to tax returns filed in 2027. The 2027 numbers will matter for income you earn during 2027 and the return you file in 2028.
How does the IRS decide the yearly inflation adjustment?
Federal law, 26 U.S.C. 1(f), ties the adjustment to the chained Consumer Price Index for All Urban Consumers, a measure published by the Bureau of Labor Statistics. The law uses the average of that index over the 12 months ending August 31. The IRS then publishes the new dollar amounts, usually in the fall, in a revenue procedure.
