2027 tax brackets vs 2026: what changes at your income

Very important disclaimer first. As of November 4, 2026, we found no 2027 figures from the IRS: its list of current news releases shows none, though the newest item on it is dated Oct. 29. The 2027 brackets here are published projections. We read Thomson Reuters Checkpoint's 2027 estimates directly and Bloomberg Tax only as reported by Accounting Today. The wage base is official and comes from SSA's notice in the Federal Register, and the same-pay figures are our own calculation on those numbers.

What does it mean for the return you file in early 2027? Nothing: that return uses the official 2026 brackets, and our income tax calculator has federal tax year 2026 for it. The figures below apply to 2027 pay, filed in 2028. We will replace them with official figures when the IRS publishes.

Projected 2027 brackets next to 2026

Long story short, in Thomson Reuters' projected 2027 tables the seven rates stay at 10% to 37%. Thresholds rise about 3.2%: Accounting Today's report on Bloomberg Tax's projections gives a 3.2% increase. Line by line against the official 2026 tables in Rev. Proc. 2025-32, the rises run 3.11% to 3.26% by our arithmetic. The single and joint deductions rise 3.11%.

Head of household has no Deduction row because the 2027 projections differ, and we won't pick one. The official 2026 amount in Rev. Proc. 2025-32 is $24,150. For 2027 the two publishers we can point to differ by up to $50, and the head of household brackets in the table are Thomson Reuters':

• Thomson Reuters projects $24,900.
• Bloomberg Tax, as reported, shows $24,925 with $24,950 in parentheses, unexplained. Its table has typos and lists 2025 deductions under 2026, so we use the report for this figure and the 3.2% and nothing else.

Rev. Proc. 2025-32 sets the official 2026 deductions at $16,100, $32,200 and $24,150. Some pages compare 2027 with $15,750 and $31,500, which are the 2025 amounts. That makes the single rise look like $850 instead of $500.

What you save on the same pay

These are our own calculations: the same wages under official 2026 rules and projected 2027 rules. Saving here means less tax on the same dollars. If prices rise about as much as the brackets, flat pay still buys less, and the saving does not change that. The table sets income tax beside Social Security, so you can see why -$923 and -$439 are both right at $250,000. Why both? Because the first is income tax alone and the second adds $483.60 more Social Security on the official 2027 wage base.

If both earn $184,500 or less or both earn $192,300 or more, read Two earners, whatever the split. If one earns $192,300 or more and the other $184,500 or less, read One earner. Anything else falls between the two.

The columns differ from $200k up, and at $400k the sign flips: -$234 with one earner, +$249 with two. By the way, we round each year's tax before subtracting, so $280.50 shows as $281 and $1,187.75 as $1,187. You may see $280 elsewhere.

Per paycheck on projected brackets, $68 is about $2.62 every two weeks and $281 is about $10.81. Not a lot of money, to be honest. We just divide the annual figure by 26, so this does not predict withholding. A paycheck moves by the employer's withholding tables and your W-4, and the Publication 15-T the IRS has online is still marked for use in 2026. Our bonus tax article shows the same gap between what payroll takes and what the year costs.

Head of household gets ranges because the deduction projections differ, net of Social Security (the low end uses Thomson Reuters' $24,900, the high end $24,950):

• $75 to $80 saved at $30,000 to $40,000
• $101 to $107 saved at $50,000 to $75,000
• $396 to $407 saved at $100,000 to $125,000
• $479 to $491 saved at $150,000
• about break-even at $200,000
• $579 to $595 saved at $250,000
• $852 to $870 saved at $300,000 to $500,000
• $1,282 to $1,301 saved at $700,000

Why the saving jumps in steps

Two things set the saving, by our arithmetic. Each threshold that moves up shifts dollars from the higher rate to the lower one, and that amount stays fixed once you are past the threshold. That's one. Second, the larger deduction takes dollars off the top at your own rate.

yearly saving = deduction rise × your rate + the sum, for each threshold you have passed, of threshold rise × (rate above − rate below)

For example, take a single filer in the 12% stretch and use the projected amounts against the official 2026 amounts. The deduction rises $500 and the 10% ceiling rises $400, so $500 × 12% + $400 × 2% = $68. That's the whole idea.

Inside a flat stretch your top rate is the same in both years, and inside a ramp it is one bracket lower on the projected 2027 figures. For example, from $66,500 to $68,625 of single wages, the top rate is 22% in 2026 and 12% in projected 2027. Hence the jump to $280.50: 10 cents on each dollar of wages across that ramp.

By our calculation, between stretches the projected saving ramps by 2 to 10 cents on each dollar of wages, so a single filer on $67,000 saves about $120. Rounding in the IRS Tax Table moves the saving by $1 or less at nearly every wage and by up to about $6 in short windows. The newest table is for 2025, so we assume the same layout for 2026 and 2027. Head of household has no lookup, because its edges move with the deduction, and the projections differ. The ranges above cover it.

You may see $171 quoted for someone earning $60,000. That is $170.50 rounded, and it treats $60,000 as taxable income and leaves out the deduction. On $60,000 of wages the projected saving is $68.

Why $200,000 can pay more

At $200,000 on projected brackets, $483.60 more Social Security outweighs $359 less income tax. So basically, it comes down to the official wage base, which rises from $184,500 to $192,300, per SSA's notice in the Federal Register. Employee tax is 6.2% up to that limit, so the $7,800 rise costs up to $483.60.

The base's 4.23% rise only explains the size. If the base rose 3.2% like the brackets, it would still add about $366 against the $359 saved, about +$7 by our arithmetic. Small, but still a rise, right?

By our calculation on projected brackets, the bill rises for a single filer from about $190,300 to about $219,400 of pay:

• Lower edge: 6.2% of pay above $184,500 reaches the $359 saving at about $190,300. Below that the Social Security rise is smaller than the saving, and below $184,500 it is zero.
• Upper edge: from $217,875 the income tax saving ramps at 8 cents a dollar and passes $483.60 at about $219,400.

Other filers, same basis:

• Couple, one earner: never.
• Couple, two earners split evenly: about $380,600 to $438,900 of household pay.
• Couple, split unevenly: a rise is possible only if both earn at least about $188,300 and household pay is in that band. Use the column rule under the joint table. For example, a $250,000 and $150,000 couple reads One earner, +$483.60 against -$718, so -$234.
• Head of household: about break-even at $200,000; the sign depends on which projected deduction turns out right.

Medicare stays out of the bill because it does not change at flat wages. Medicare has no wage base limit, and the $200,000 and $250,000 Additional Medicare lines in the statute carry no inflation adjustment.

The extra lands late in the year. Let's say you are paid every two weeks at $200,000. You reach the 2026 cap in paycheck 24 and the 2027 cap in paycheck 25, so by our arithmetic all of the $483.60 comes out of those two paychecks.

If your pay rises 3.2% too

Now let's look at a raise as well. Indexing is what stops bracket creep: the law adjusts the bracket tables for inflation each year. The Saved column is its dollar value at a raise of 3.2%, by our calculation on projected brackets.

On projected brackets, federal income tax rises $124 to $793 on the raise and the effective rate stays within 0.01 of a point. That rise is $68 to $359 smaller than with 2026 brackets.

A raise does not cancel the $200,000 rise. Take $206,400: projected 2027 rules against 2026 rules give income tax -$359 ($37,911 vs $38,270) and Social Security +$483.60, net +$124.60, with Additional Medicare the same under both since its $200,000 threshold is not indexed.

What these figures leave out, and how they were worked out

Every figure uses wages only and the standard deduction, for a filer under 65, without:

• credits or other deductions, such as the car loan interest deduction
• state tax
• married filing separately and surviving spouses
• pre-tax deductions
• couples split any way other than one earner or evenly, apart from the column rule and the band rule above

The 2026 side matches our calculator at every point we checked, and the 2027 side is a script run with the projected values, so none of it is calculator output.

One more disclaimer: the bracket projections work around a gap. Thomson Reuters says no October 2025 CPI was published and used 11 months. Filling in that reading by interpolation gives about 3.06% by our arithmetic, against 3.19% on the 11 months. Our own re-run of these figures on that basis moves results by $1 to $11 for single and $0 to $16 for joint up to $200,000 and by $16 to $82 from $250,000 to $700,000. Single at $200,000 stays a rise in every set we ran, $124.60 to $135.60. Official figures may differ.

Questions people ask

When will the 2027 tax brackets be released?

Not yet as of November 4, 2026, going by the IRS list of current news releases. Past releases came on Oct. 9, 2025 (IR-2025-103), Oct. 22, 2024 (IR-2024-273), Nov. 9, 2023 (IR-2023-208) and Oct. 18, 2022 (IR-2022-182). A social post titled "announced" or "released" does not change that status. The IRS list does.

What is the standard deduction for 2027?

Not official yet. Thomson Reuters projects $16,600 single and $33,200 joint. Head of household projections differ: $24,900 from Thomson Reuters and up to $24,950 from Bloomberg Tax, as reported. Rev. Proc. 2025-32 sets the official 2026 amounts at $16,100, $32,200 and $24,150.

Do the 2027 brackets apply to the taxes I file in 2027?

No. The IRS says the tax year 2026 figures generally apply to returns filed in 2027. The 2027 brackets apply to 2027 pay, filed in 2028. Our income tax calculator has federal tax year 2026 only, so it covers the return you file in 2027 and does not cover 2027 pay.

What is the Social Security tax limit for 2027?

$192,300, up from $184,500, both official in SSA's Federal Register notice. At the 6.2% employee rate the maximum tax goes from $11,439 to $11,922.60, so up to $483.60 more.

How much federal tax do you pay on $100,000?

Income tax on $100,000 of wages with the standard deduction, 2026 to projected 2027, by our calculation. These use Tax Table rows, so they sit a few dollars above the bracket tables worked directly:

• Single: $13,176 to $12,895
• Joint: $7,643 to $7,507
• Head of household: $9,594 to between $9,187 and $9,198, depending on which projected deduction turns out right

What is the standard deduction if you are over 65?

The brackets are the same at 65 or older, since the tables go by filing status. Only the deduction differs. Thomson Reuters projects the addition at $2,100 single or head of household and $1,700 per spouse on a joint return, from $2,050 and $1,650 in 2026. The statute gives it for each spouse. Totals, 2026 to projected 2027:

• Single: $18,150 to $18,700
• Head of household: $26,200 to $27,000 or $27,050, because the deduction projections differ
• Joint, both 65 or older: $35,500 to $36,600

What is the new $6,000 standard deduction for seniors?

It is separate from the standard deduction and added on top of the 65-or-older addition, and it is not computed in this article. Per the IRS fact sheet: age 65 or older, tax years 2025 to 2028, $6,000 per eligible person, $12,000 if both spouses qualify. You must file jointly if married, and it is open to itemizers and non-itemizers. It phases out above $75,000 of modified AGI ($150,000 joint). Thomson Reuters gives the reduction as 6% of the excess.

Where does the 22% tax bracket start in wages?

Only dollars above the line are taxed at 22%. Wages where 22% begins, 2026 to projected 2027, by our calculation from the official 2026 tables, Thomson Reuters' projection and, for the $94,600, the $24,950 reported for Bloomberg Tax:

• Single: $66,500 to $68,625
• Joint: $133,000 to $137,250
• Head of household: $91,600 to $94,550 or $94,600, because the deduction projections differ
