Your 2027 Brackets Are Coming. Here’s How to Use Them Before Dec. 31st
The IRS will publish official 2027 tax brackets in weeks, but December 31 will not wait. A few moves made before midnight could shift thousands of dollars between tax rates, and the window closes whether you act or not.

The IRS hasn’t published its official 2027 tax brackets yet, but they’re close. Wolters Kluwer says the agency usually releases its inflation adjustments in late October or early November. Until then, the best guide is a projection the CCH AnswerConnect editorial team at Wolters Kluwer published Sept. 18, 2026.
Wolters Kluwer notes the October 2025 consumer price index report never came out because of the 2025 government shutdown, so its projection uses an inflation average that skips that month. The official IRS amounts may differ.
The projection is still good enough to plan with, and Dec. 31 is the deadline for most of the moves that matter.
Official 2026 Brackets Versus Projected 2027 Lines
The 2026 figures come from IRS release IR-2025-103 and Revenue Procedure 2025-32, and they generally apply to tax returns filed in 2027. Every 2027 figure below is a Wolters Kluwer projection.
Single Filers: Each Rate Starts Above
| Rate | 2026 Official | 2027 Projected |
|---|---|---|
| 12% | $12,400 | $12,800 (Wolters Kluwer) |
| 22% | $50,400 | $52,025 (Wolters Kluwer) |
| 24% | $105,700 | $109,125 (Wolters Kluwer) |
| 32% | $201,775 | $208,325 (Wolters Kluwer) |
| 35% | $256,225 | $264,550 (Wolters Kluwer) |
| 37% | $640,600 | $661,375 (Wolters Kluwer) |
Married Filing Jointly: Each Rate Starts Above
| Rate | 2026 Official | 2027 Projected |
|---|---|---|
| 12% | $24,800 | $25,600 (Wolters Kluwer) |
| 22% | $100,800 | $104,050 (Wolters Kluwer) |
| 24% | $211,400 | $218,250 (Wolters Kluwer) |
| 32% | $403,550 | $416,650 (Wolters Kluwer) |
| 35% | $512,450 | $529,100 (Wolters Kluwer) |
| 37% | $768,700 | $793,650 (Wolters Kluwer) |
Standard Deduction Projected to Climb in 2027
| Filing Status | 2026 Official | 2027 Projected |
|---|---|---|
| Married filing jointly | $32,200 | $33,200 (Wolters Kluwer) |
| Single (and married filing separately) | $16,100 | $16,600 (Wolters Kluwer) |
| Head of household | $24,150 | $24,950 (Wolters Kluwer) |
Use Up Your 22% Bracket Before It Resets
Brackets are fill lines. Room you leave empty in 2026 is gone for good on Dec. 31. Consider a hypothetical retired couple filing jointly whose 2026 taxable income falls inside the 22% bracket, with $40,000 of room left before the 24% rate starts at $211,400.
If they convert that $40,000 from a traditional IRA to a Roth, all of it is taxed at 22%, for about $8,800 in federal tax. The same amount taxed at 24% would cost $9,600. Extra IRA withdrawals and realized capital gains use the same room, since gains add on top of ordinary income (the low-bracket years between retirement and RMDs are the whole subject of our free Roth conversion guide).
Watch Medicare, though. Any extra income increases your modified adjusted gross income (MAGI), and Medicare uses MAGI from two years earlier to set premiums. In 2026, the first Part B surcharge applied to joint filers above $218,000 and single filers above $109,000. The tiers that will apply to 2026 income haven’t been published yet.
Push Income That Can Wait Into 2027
When thresholds rise, the same dollar can land in a lower bracket next year. CCH AnswerConnect Editorial at Wolters Kluwer projects the 2027 joint 22% bracket will top out at $218,250. Under the official 2026 schedule, the 24% rate starts above $211,400.
Income you control is worth a look: a year-end bonus, an IRA distribution beyond your required amount, or a property sale you could close in January. Never put off a required minimum distribution (RMD), since missing one brings a penalty.
Postponing backfires if your income will jump in 2027. That can happen when RMDs start, when Social Security begins, or when a big sale is already planned. In those years, slightly higher brackets won’t absorb the extra income.
Bunch Deductions Into 2026, Then Take the Bigger Standard Deduction
The 2026 joint standard deduction is $32,200, and CCH AnswerConnect Editorial projects $33,200 for 2027. If you give to charity, consider packing two years of gifts into December, perhaps through a donor-advised fund. You itemize in 2026, then take the larger standard deduction in 2027.
Check one wrinkle first: the sweeping tax bill imposes a limitation on the tax benefit from itemized deductions for some high earners.
What to Check When the IRS Releases the Official Numbers
Look for a new revenue procedure with the 2027 brackets and standard deductions, and compare it against the projections above. If a move depends on landing just under a threshold, wait for the final figures or leave yourself a margin. State income taxes follow their own rules.
Roth conversions and income timing are the kind of math worth running with a fiduciary advisor or CPA before Dec. 31.
