2027 Tax Brackets: Modest Savings, Same Rates and Lessons From 30 Years

Here's the thing about the 2027 brackets: the headline numbers look bigger than the money you'll actually keep. The IRS raised every income threshold by about 3.2%, lifted the standard deduction by $500 for single filers and $1,000 for married couples, and left all seven rates at 10%, 12%, 22%, 24%, 32%, 35% and 37%. For most households that adds up to a few hundred dollars or less. A single person earning $100,000 will owe $280 less than in 2026 on the same salary, and a married couple at $100,000 will owe $136 less.

That's by design. The adjustment keeps inflation from nudging you into a higher bracket, so a raise that matches inflation roughly keeps your rate where it was.

What Applies to 2027 Income

These brackets cover income earned in 2027, which you'll report on the return you file in early 2028. Each rate applies only to the slice of taxable income inside its range, so moving up a bracket never taxes all of your income at the higher rate. The standard deduction, which most taxpayers subtract before the brackets apply, also rises.

How Capital Gains Stack

Long-term capital gains, meaning profits on investments held more than a year, have three rates of their own. Qualified dividends use the same table, and the thresholds depend on your total taxable income, including the gain. Think of the gain as sitting on top of everything else. Wages, interest and other ordinary income fill the regular brackets first, after the standard deduction, and the gain lands above that.

Take a single filer with $40,000 of taxable wages and a $20,000 long-term gain. The first $11,050 of the gain fills the space up to $51,050 and is taxed at 0%. The remaining $8,950 is taxed at 15%, or $1,343. The gain doesn't push any wage income into a higher bracket. Gains held a year or less are short-term and taxed at ordinary rates.

What the New Tables Save

At the same salary, the 2027 tables trim the typical federal income tax bill by 1% to 2%. For a single filer taking the standard deduction, savings run from $68 at a $60,000 salary to about $1,600 at $750,000. For married couples, they range from $136 at a $100,000 combined salary to about $2,900 at $1 million combined.

Those figures assume flat pay. Prices rose 3.7% over the year ended in September, and a raise that size wipes out the savings. Measured in equal buying power, the 2027 bill comes out 0.1% to 0.7% higher than the 2026 bill across those same incomes, a difference of $13 to $460. The tables help, but not enough to outrun prices.

Ten Years on the Same Rates

The current seven rates took effect in 2018, and the IRS has raised thresholds every year since. Adjusted for inflation, the 2027 bill lands within about 1.5% of the 2018 bill at every income level. Prices rose roughly 37% over that stretch, so $100,000 today is comparable to about $73,100 in 2018 buying power.

Someone whose salary has been frozen since 2018 pays noticeably less tax now, but that salary also buys about 27% less. Someone whose raises kept pace with prices pays almost the same share of income as in 2018. A single filer with $100,000 of today's buying power paid 12.83% then and will pay 12.89% in 2027.

Most after-inflation differences sit slightly above zero because thresholds rose 32% to 34% since 2018 while prices rose about 37%. The IRS indexes brackets to an inflation measure that runs a bit cooler than the headline figure. The standard deduction climbed 38% over the same period, helped by the 2025 tax law, which is why the lowest incomes come out slightly ahead.

Three Eras of Federal Rates

Bills move far more when the rates themselves change, and that has happened only a few times in three decades. Applying each era's rules to today's buying power makes the pattern clear. A single person with $100,000 of today's buying power would owe about a third more under the 2000 rules than under the 2027 rules, and a married couple at $150,000 would owe 58% more. In both cases that's roughly four percentage points of salary, because the rate on each slice fell by three to six points and most middle-earner income sits in the lower brackets under either system.

The 2012 and 2017 results are nearly identical below about $400,000, since the 2013 change reached mainly the highest earners. High earners have gained the least. At $750,000, a single filer owes slightly more under 2027 rules than under 2012 rules, while a married couple at $1 million owes about 6% less.

Permanent, But Not Locked In

The 2018 rates were originally set to expire after 2025. The tax law signed in July 2025 made them permanent, along with the larger standard deduction and the end of the personal exemption, which was last available in 2017. Permanent means no built-in end date, not immunity from future changes. Several newer 2025 deductions are temporary, including the $6,000 deduction for taxpayers 65 and older and the deductions for tips and overtime pay, which end after 2028.

How the Numbers Were Built

• Examples assume wage income only, the standard deduction, no children and no tax credits.
• Figures for 2017 and earlier include the personal exemption and its phase-out at high incomes.
• Where the alternative minimum tax produced a higher bill, that amount is shown. It applies to married couples at $500,000 and $650,000 under 2012 rules.
• Inflation uses the Consumer Price Index for All Urban Consumers, based on October figures for each tax year, with the 2027 comparison covering the 12 months through September 2026.

What to Take From It

For 2027, expect modest relief if your income stays flat, and keep in mind that a raise matching inflation mostly keeps you where you started. Your marginal bracket only sets the rate on the top slice of your income, not the whole paycheck. Over three decades, though, changes to the law have moved tax bills far more than the yearly inflation adjustments. Today's rates are permanent under current law, but current law can still change, so it's worth keeping an eye on.
