2027 Tax Brackets: Projected Standard Deduction, 401(k) and IRA Limits and What the IRS Has Not Yet Announced

The 2027 tax brackets are not official yet. As of the latest reports we could find, dated October 19, the IRS had not published its inflation adjustments for the 2027 tax year, and it had not said when it would. The agency released the 2026 numbers on October 9 of last year and the 2025 numbers on October 22 of the year before, so a late October or November release would not be unusual. The best available preview is a projection from Bloomberg Tax, reported by CBS News: income thresholds for all seven brackets rising 3.2 percent, up from 2.7 percent for 2026, and a standard deduction of $16,600 for single filers and $33,200 for married couples filing jointly. We’ll be updating this article monthly.

The projected changes are modest in dollars. For a single filer earning $60,000 in wages, the projection implies federal income tax falling by about $68, from $5,020 to $4,952, and for a married couple with the same combined income by about $136, from $2,840 to $2,704, according to Cronista’s calculation from the Bloomberg numbers. The 401(k) limit is also expected to rise, by an estimated $1,000 to $25,500, but that figure comes from calculations by The White Coat Investor, not from an IRS notice. Last year the IRS announced the retirement plan limits on November 13, more than a month after the brackets. This guide separates what is official from what is projected, compares 2027 with the official 2026 figures, explains which tax return each set of numbers applies to, and includes a free estimator that runs your income through both years.

Treat anything labeled projected as an estimate. The Money Overview noted that the IRS’s inflation adjusted table still ended at tax year 2026 as of October 14 and that the agency had not said when it will publish. The CBS News piece quoted Bloomberg’s caution that the final numbers could differ.

When Will the IRS Announce the 2027 Tax Brackets?

Two dates are worth watching. The brackets and standard deduction normally come first, in a revenue procedure and news release. The retirement plan limits usually follow in a separate notice, which was mid November last year. If the pattern holds, plan for a release of the brackets any day and the retirement limits by the end of November, but the agency has not committed to either.

How the 2027 Tax Brackets Are Projected: The 3.2 Percent Estimate

The IRS adjusts brackets each year using the chained consumer price index, the measure published by the Bureau of Labor Statistics. Bloomberg Tax’s forecast was released on September 11. One wrinkle in the math: because October 2025 inflation data was not reported during the government shutdown, Bloomberg used an 11 month average to get its estimate, CBS News reported.

That is why the official figures could differ even if the 3.2 percent is close. The CBS article also noted that August consumer prices showed annual inflation of 3.4 percent, higher than expected, and the Bureau of Labor Statistics reported 3.7 percent for September. Those readings do not change the projection by themselves, because the IRS formula follows its own measure and period, but they are a reminder that the final numbers could land above or below the estimate.

2026 Tax Brackets (Official) Compared With 2027 (Projected)

The tables show the income at which each rate begins to apply, using taxable income after the standard deduction.

35 percent$512,450$529,100
37 percent$768,700$793,650

The 2026 figures are from the Journal of Accountancy’s report on Revenue Procedure 2025-32, and the 2027 figures are from Bloomberg Tax’s projection as reported by Cronista. CBS News reported the joint 10 percent bracket ending at $25,601 where Cronista shows $25,600, a one dollar difference that is likely a rounding or presentation choice. The tax rates themselves, 10 to 37 percent, do not change.

2027 Standard Deduction: Projected Increase

Filing status2026 official2027 projected
Single and married filing separately$16,100$16,600
Married filing jointly$32,200$33,200
Head of household$24,150Not found in our sources

A larger standard deduction shrinks taxable income for everyone who does not itemize, which is most filers. One caution about numbers you may see online: some summaries pair the 2027 projection with the prior year’s deduction of $15,750 and $31,500. Those are 2025 figures. The official 2026 numbers are $16,100 and $32,200.

What the Projected Changes Mean in Dollars

Cronista used wage income only, the standard deduction, no credits and no change in pay.

Filer with $60,000 of wages2026 tax2027 projected taxDifference
Single$5,020$4,952About $68 lower
Married filing jointly, combined income$2,840$2,704About $136 lower

The single filer’s taxable income falls from $43,900 to $43,400, and the 10 percent bracket covers the first $12,800 instead of $12,400. The effect is real but small, because the adjustment mostly keeps pace with price increases rather than giving a raise.

That is the idea of bracket creep, which CBS News described as a hidden tax hike that can occur when income bands do not keep pace with inflation. Indexing is what prevents it. If your pay rises faster than 3.2 percent in 2027, part of the extra can still push you across a bracket line, but the lines themselves will be a little higher.

Which Tax Return Do the 2027 Brackets Apply To?

This confuses a lot of people, so here it is plainly.

Income earnedReturn filedBrackets used
January to December 2026Early 2027, usually by mid April2026 brackets and standard deduction
January to December 2027Early 2028, usually by mid April2027 brackets and standard deduction

The 2027 brackets do not affect the return you file next spring. They matter for planning, such as withholding changes, raises, Roth conversions and how much you contribute to a retirement account.

2027 401(k) and IRA Contribution Limits: Projected Against 2026

The 2026 limits are official, announced November 13, 2025. The 2027 column is calculated by The White Coat Investor and is not an IRS figure.

Item2026 official2027 projected
401(k), 403(b) and 457(b) employee deferral$24,500$25,500
Catch-up, age 50 and older$8,000$8,500
Total for age 50 and older$32,500$34,000
Super catch-up, ages 60 to 63$11,250$11,750
Total for ages 60 to 63$35,750$37,250
Total employee and employer limit, under 50$72,000$75,000
Traditional and Roth IRA$7,500$7,500
IRA catch-up, age 50 and older$1,100$1,100
SIMPLE IRA or 401(k)$17,000$17,500
Annual compensation limit$360,000$375,000
Highly compensated employee threshold$160,000$170,000
Roth catch-up wage threshold$150,000$155,000

The 2026 numbers come from Notice 2025-67 as summarized by 401(k) Specialist Magazine, except the Roth catch-up threshold and the 2026 super catch-up total, which are the White Coat Investor’s figures and our own addition. If the projection holds, the biggest changes would be a $1,000 increase in the 401(k) deferral and a $500 increase in the catch-up, while the IRA limit would stay at $7,500, since IRA limits move in steps and the projection does not reach the next step.

IRA Income Limits for 2027: Roth and Deductibility Phaseouts

Phaseout2026 official2027 projected
Roth IRA, married filing jointly$242,000 to $252,000$250,000 to $260,000
Traditional IRA deduction, single with a workplace plan$81,000 to $91,000$83,000 to $93,000
Traditional IRA deduction, married filing jointly, contributor covered by a plan$129,000 to $149,000$133,000 to $153,000

The White Coat Investor also listed a projected 2027 Roth IRA phaseout for single filers of $158,000 to $168,000, with an unchanged upper end that it flagged as possibly a typo, so we are leaving that line out until the IRS publishes. The 2026 single Roth range is $153,000 to $168,000.

HSA, family$8,750$9,000
HSA catch-up, age 55 and older$1,000$1,000
Healthcare flexible spending account$3,400$3,500

These come from the same projection and are not official. HSA limits are announced separately by the IRS, usually in the spring, so the official 2027 figures may not arrive for months.

Official 2027 Numbers You Can Use Today

A few 2027 figures are already confirmed. The employer coverage affordability threshold for plan years beginning in 2027 is 10.22 percent of household income, Bloomberg Tax reported on July 22 from the IRS’s revenue procedure. The Social Security Administration’s fact sheet puts the 2027 maximum taxable earnings at $192,300, up from $184,500. And the earnings limits for people who collect Social Security while working are $25,560 a year for those under full retirement age and $67,920 in the year they reach it.

The maximum employee share of the 6.2 percent Social Security tax at the taxable maximum rises from $11,439 to $11,922.60, according to Newsweek. These are payroll tax numbers, separate from the income tax brackets.

Senior Deduction and Other Provisions to Check in the Final Release

The 2025 tax law created a $6,000 deduction for adults 65 and older, and the White House Council of Economic Advisers estimated that 88 percent of Social Security beneficiaries would owe no federal income tax on benefits during the four year window, TheStreet reported. The Money Overview suggested checking how the senior deduction is treated in the IRS’s 2027 release because it affects taxable income. We could not find a projected 2027 figure for it, so the estimator below does not include it.

How to Use the Projected 2027 Numbers for Planning

This is general information, not tax advice.

  1. Use 2026 for 2026 decisions. The Money Overview advised using the 2026 figures as the current reference points and rerunning any plan when the IRS publishes the 2027 numbers.
  2. Test scenarios against the bracket lines. If you are considering a Roth conversion or an IRA withdrawal, see how close you are to a bracket edge.
  3. Do not change withholding yet. Wait for the official numbers and the IRS withholding tables.
  4. Plan to raise your 401(k) contribution when the limit is confirmed, particularly if you are 60 to 63 and eligible for the higher catch-up.
  5. If you are a high earner, check the Roth catch-up rule. The projected wage threshold is $155,000 for 2027.
  6. Keep records of your 2026 income. You will use the official 2026 figures for the return you file in the spring.

How to Find the Official Numbers, Processing and Timing

There is nothing to apply for, but there is a timeline to follow.

How to find them: the IRS publishes the brackets in a revenue procedure and a news release, and the retirement limits in a notice, on its newsroom. Timing: the brackets have been announced between early and late October in recent years, and the retirement notice in mid November. Payments: no payment is involved, but your paycheck withholding is based on the IRS tables, which are updated after the brackets are announced. Employers typically update payroll systems for the new year, so check your first paycheck of the year.

They are not official yet. Bloomberg Tax projects all seven bracket thresholds rising 3.2 percent, with rates unchanged at 10 to 37 percent.

What is bracket creep?

When income thresholds do not keep up with inflation and taxpayers pay more even though their real income has not risen.

Conclusion

The 2027 tax brackets are still a projection. The IRS has not published them, and the best estimate calls for a 3.2 percent increase in every bracket threshold, a $16,600 single and $33,200 joint standard deduction and a 401(k) limit near $25,500. For a typical wage earner that adds up to tax savings of tens or low hundreds of dollars, not thousands.

The official numbers should arrive in the coming weeks, with retirement limits likely to follow, so use 2026 for decisions you must make now and rerun your plan when the IRS publishes. Check back for our next update, because we revise this guide every month.
