As of October 14, the IRS had not published the 2027 tax brackets, the 2027 standard deduction or any other inflation-adjusted figure for the coming tax year. The agency’s table of inflation-adjusted tax items still ends at tax year 2026, and its newest press releases cover diesel fuel penalties, health-credit rules and a British whistleblower program instead of next year’s thresholds. The silence leaves a gap, because the same announcement fixes the income levels where the 10%, 12% and 22% rates begin and end, and planning for 2027 now rests on private estimates.
The question for retirees who control their own taxable income is when the real numbers will arrive. Anyone sizing IRA withdrawals or a Roth conversion for 2027 needs the bracket edges to know how much room remains in the 12% band before income spills into 22%. The IRS has not said when it will publish. Its last two announcements came October 9 and October 22, so a release in the next several weeks would fit the pattern, though the agency has made no commitment.
Until the 2027 bracket edges post, a retiree has no official line for how far a withdrawal or Roth conversion can go before the 22% rate starts. The Retirement Tax & Withdrawal Planner includes four calculators (provisional income, IRMAA tier, RMD schedule, Roth bracket fill) built for testing exactly that kind of move.
What the IRS pages show on October 14
The IRS lists its yearly adjustments on a single page, and the 2026 entries sit at the top. They include a release on the tax-year 2026 brackets and a separate one headlined “401(k) limit increases to $24,500 for 2026, IRA limit increases to $7,500.” The page carries no 2027 entry for either set of figures, and its footer shows a last-updated date of December 1, 2025, so nothing has been added since the 2026 numbers were posted.
The agency’s list of October news releases points the same way. It runs from IR-2026-117 on October 1, a call for volunteers for free tax-preparation programs, through IR-2026-122 on October 14, a decision not to penalize dyed diesel fuel used on highways. Releases 121 and 120 cover proposed Premium Tax Credit regulations and the IRS partnership with the British tax authority’s whistleblower program. None mentions next year’s brackets or deductions.
How late the IRS has run in earlier years
The two most recent announcements fell in the same window. The IRS posted the 2026 figures on October 9, 2025, in release IR-2025-103, with the figures set out in Revenue Procedure 2025-32. The 2025 figures came later in the month: release IR-2024-273 on October 22, 2024, with Revenue Procedure 2024-40. The 2027 release has not appeared by October 14, which is neither unusually early nor late by either benchmark.
Those two releases also show what is at stake. For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household. The 10% bracket ends at $12,400 of taxable income for singles and $24,800 for joint filers, and the 12% bracket stops at $50,400 and $100,800. The top 37% rate begins above $640,600 for singles and $768,700 for joint filers. In 2025 the standard deduction was $15,000 and $30,000, and the 37% rate began at $626,350 and $751,600.
Private estimates stand in for the numbers
With the IRS silent, the only 2027 figures in circulation are projections. CBS News reported in September that Bloomberg Tax estimates a 2027 standard deduction of $33,200 for married couples filing jointly and $16,600 for single filers, and that bracket thresholds will rise 3.2%, compared with 2.7% for 2026. CBS said the IRS had not announced its figures and did not respond to a question about timing. The estimates follow the chained Consumer Price Index, the measure the IRS uses.
One quirk in those projections comes from the 2025 government shutdown, which kept the October 2025 inflation report from being published. To fill the gap, Bloomberg Tax built its index from an 11-month average. The projected joint standard deduction is $1,000 above the 2026 figure of $32,200, and the single deduction is $500 above $16,100. Bloomberg Tax also projects the top of the joint 12% bracket at $104,050, up $3,250 from the 2026 line of $100,800.
Reading the 2027 brackets once they post
When the IRS publishes, the release and its revenue procedure will appear on the agency’s inflation-adjusted items page, where the 2027 section does not yet exist. The first numbers to compare are the ones that already govern a retiree’s plan: the 2026 joint 12% bracket ceiling of $100,800, the single ceiling of $50,400, and the standard deductions of $32,200 and $16,100. A shift larger or smaller than Bloomberg Tax’s 3.2% would change how much income fits under each ceiling.
The senior deduction added by the One, Big, Beautiful Bill is the other open item. The IRS’s 2026 release notes that its personal exemption figure leaves out that deduction and gives no amount or eligibility rules. Retirees using it will want to see how the agency’s 2027 release treats it, since the standard deduction and the senior deduction work together in setting taxable income.
The gap between estimate and fact is small in dollars and large for planning. A projected $104,050 ceiling for the joint 12% bracket is $3,250 above the current $100,800, and a Roth conversion sized to the old line could end up either short of the new one or past it. Bloomberg Tax’s figures rest on an 11-month inflation average, which is why the IRS revenue procedure, not the projection, will settle the 2027 line.
The 2027 bracket edge is still a projection
The projected $104,050 ceiling for the joint 12% bracket could shift when the IRS publishes, and a Roth conversion sized to the wrong edge costs real tax. The 18-page Retirement Tax & Withdrawal Planner includes the senior deduction and four calculators (provisional income, IRMAA tier, RMD schedule, Roth bracket fill), so a conversion can be re-run the day the IRS numbers land.
