Where the 12% Bracket Ends in 2026: $100,800 for Married Couples Filing Jointly
For married couples filing jointly in 2026, the 12 percent bracket covers taxable income from $24,801 to $100,800; the next dollar is taxed at 22 percent. With the $32,200 standard deduction, that ceiling sits at roughly $133,000 of gross income. The gap between a couple’s income and that line is space that resets every January.
During working years, tax brackets are mostly something that happens to a household. In the years between retirement and required minimum distributions, they start to behave more like a measured container: a fixed amount of space each year, taxed at a known rate, that either gets used or expires on December 31. For married couples in 2026, the edge of the most useful container is exact. The 12 percent bracket ends at $100,800 of taxable income.
What follows is educational and covers federal income tax. How it applies to a particular return should be confirmed with a tax professional.

What the Bracket Question Is Really Asking
Asking where the 12 percent bracket ends is usually a way of asking something more practical: how much more income can we recognize this year before the rate on the next dollar almost doubles? The answer requires three numbers, not one: the bracket line, the deductions beneath it, and the income already on the return. The gap between the last two and the first is what planners call headroom.
The 2026 Brackets
IRS Revenue Procedure 2025-32 sets the inflation-adjusted brackets for 2026. (IRS Rev. Proc. 2025-32, §4.01)
| Rate | Married filing jointly (taxable income) | Single (taxable income) |
|---|---|---|
| 10% | Up to $24,800 | Up to $12,400 |
| 12% | $24,801 to $100,800 | $12,401 to $50,400 |
| 22% | $100,801 to $211,400 | $50,401 to $105,700 |
| 24% | $211,401 to $403,550 | $105,701 to $201,775 |
| 32% | $403,551 to $512,450 | $201,776 to $256,225 |
| 35% | $512,451 to $768,700 | $256,226 to $640,600 |
| 37% | Above $768,700 | Above $640,600 |
Three features of the table carry most of the planning weight:
- The rates are marginal. Crossing $100,800 does not reprice the return. Only the dollars above the line pay 22 percent. A couple with exactly $100,800 of taxable income owes $11,600: $2,480 on the first $24,800 and 12 percent of the next $76,000.
- The 12-to-22 step is the steep one. The rate nearly doubles at that line, while the next step, from 22 to 24, is two points. The top of the 12 percent bracket is where the cost of a marginal dollar changes most.
- Brackets apply to taxable income. With the 2026 joint standard deduction of $32,200, the 12 percent ceiling sits at $100,800 + $32,200 = $133,000 of gross income. (IRS Rev. Proc. 2025-32, §4.14)
For couples 65 and older, the line moves up. Each spouse adds $1,650 to the standard deduction, and from 2025 through 2028 each can claim the $6,000 senior deduction. (26 U.S.C. §151(d)(5)) With both spouses over 65, deductions total $47,500, and the 12 percent ceiling moves to about $148,300 of gross income. That sits just below the $150,000 of modified AGI where the senior deduction begins to phase out.
$133,000 of gross ordinary income for a couple on the basic $32,200 deduction; about $148,300 for a couple both 65 or older through 2028. Below those lines, no dollar is taxed above 12 percent.
A Hypothetical Couple, Worked Through
This illustration is hypothetical and simplified. It is not based on any client, assumes all income is ordinary income, and is not a recommendation for any household.
A married couple, both 63, has retired and lives on a $40,000 pension while delaying Social Security. Their 2026 return:
| Line | Amount |
|---|---|
| Gross income | $40,000 |
| Standard deduction | −$32,200 |
| Taxable income | $7,800 |
| Top of the 12% bracket | $100,800 |
| Headroom through the 12% bracket | $100,800 − $7,800 = $93,000 |
That $93,000 is space in which additional ordinary income, most often a Roth conversion, is taxed at no more than 12 percent. If the couple filled it exactly, the first $17,000 would land in the rest of the 10 percent bracket and the next $76,000 at 12 percent: $1,700 + $9,120 = $10,820 of added federal tax, an average of about 11.6 percent. Their total federal tax would be $780 + $10,820 = $11,600, the figure at the top of the 12 percent bracket.
Once both spouses turn 65, their deductions rise to $47,500 and the same pension leaves $148,300 − $40,000 = $108,300 of headroom through 2028. Once Social Security begins, the headroom shrinks by the taxable share of the benefits; once required distributions begin, at 73 or 75 depending on birth year, it shrinks again.
Why the Ceiling Matters for Conversions
A Roth conversion is taxed as ordinary income in the year it happens, and since 2018 it cannot be undone. (IRS Publication 590-A) The bracket it lands in sets its price.
| Where $10,000 of conversion income lands | Federal tax |
|---|---|
| Inside the 12% bracket | $10,000 × 12% = $1,200 |
| Inside the 22% bracket | $10,000 × 22% = $2,200 |
The ten-point spread is worth $1,000 for every $10,000 converted, and the couple above has $93,000 of 12 percent space. The years when that space is widest usually fall between the last paycheck and the first Social Security check or required distribution.
Two formulas complicate the clean bracket arithmetic, and each runs on its own definition of income:
- Social Security taxation. Once benefits begin, provisional income above $32,000 on a joint return makes up to 50 percent of benefits taxable, and above $44,000 up to 85 percent. (26 U.S.C. §86) The $32,000 line dates from the 1983 amendments and the $44,000 line from 1993 legislation; neither is indexed. (SSA, income taxes on Social Security benefits) In the 85 percent range, one more dollar of IRA income can add $1.85 of taxable income, so a couple nominally in the 12 percent bracket pays about 12% × 1.85 = 22.2 percent on that dollar.
- Medicare IRMAA. For Medicare enrollees, joint modified AGI above $218,000 in 2026 triggers premium surcharges, generally based on the return from two years earlier. It is a cliff, not a slope. (CMS, 2026 Part B premiums; 20 CFR §418.1135) The 12 percent ceiling sits well below it.
Space left unused in the 2026 brackets does not carry into 2027. Each January brings a new, inflation-adjusted container, and the old one is gone.
How We Approach This in a Plan
We measure 12 percent headroom for each year of a plan, not just the current one, because the question is always which year’s space is cheapest to use.
- Conversions against future rates. Filling the bracket helps only if the same dollars would later be taxed at more than 12 percent, through RMDs, a survivor’s single-filer brackets, or heirs’ own rates. See when Roth conversions pay off and the window before required withdrawals.
- The survivor’s brackets. A surviving spouse can generally file jointly for the year of death, then usually moves to single rates, where the 12 percent bracket ends at $50,400. (IRS Publication 501; IRS Rev. Proc. 2025-32) Income that fit comfortably at 12 percent for two can reach 22 or 24 percent for one; see the first year after a spouse dies.
- Social Security timing. Delaying benefits keeps provisional income low in the conversion years; see the tax torpedo.
- Deductions and gains. The deduction layer beneath the brackets is covered in the 2026 standard deduction for retired couples. Conversion income also displaces room for gains at 0 percent; see the 0 percent capital gains bracket.
- Account order. Which account funds spending changes how much headroom is left; see withdrawal sequencing.
Questions Worth Answering Before You Decide
- What will this year’s taxable income be before any conversion or extra withdrawal?
- How far is that from $100,800, and how will the gap change when each spouse turns 65, claims Social Security, and reaches RMD age?
- What rate is likely to apply to these dollars later, for the couple, for a surviving spouse, or for heirs?
- Is any of the income in the range where Social Security taxation raises the effective marginal rate?
- How close is modified AGI to the IRMAA line two years out?
- Is cash available outside the IRA to pay the tax on a conversion?
What This Does Not Mean
- It does not mean the bracket should be filled. A household whose future rate is likely to be 12 percent or lower gains nothing by paying tax early.
- It does not mean crossing $100,800 is a mistake. Only the dollars above the line pay 22 percent; everything below keeps its rate.
- It does not stay fixed. Brackets adjust for inflation each year, and Congress can change them.
- It does not cover every rate. Social Security taxation, IRMAA and state income taxes follow their own rules.
- It is not personalized advice. How much headroom to use belongs in a household’s full projection, reviewed with a tax professional.
Frequently Asked Questions
Q: Where does the 12% bracket end for married couples in 2026?
At $100,800 of taxable income for married couples filing jointly, per IRS Rev. Proc. 2025-32. With the $32,200 standard deduction, that is roughly $133,000 of gross income.
Q: Where does the 12% bracket end for single filers in 2026?
At $50,400 of taxable income. With the $16,100 standard deduction for single filers, that is about $66,500 of gross income before age-based deductions.
Q: If our income goes over $100,800, is all of it taxed at 22%?
No. Brackets are marginal. Only the dollars above $100,800 are taxed at 22 percent; a $1,000 overage costs $220 instead of $120, and nothing else on the return changes rate.
Q: What is bracket headroom?
The distance between current taxable income and the top of a chosen bracket. A couple with $7,800 of taxable income has $93,000 of room before reaching the 22 percent bracket in 2026.
Q: Why does the 12% ceiling matter for Roth conversions?
Conversion income is ordinary income, so the bracket it lands in sets its cost: $10,000 inside the 12 percent bracket costs $1,200, against $2,200 at 22 percent. Social Security taxation and IRMAA can change the true marginal rate.
Q: Does unused bracket space carry over to the next year?
No. Bracket space is measured one tax year at a time. What goes unused in 2026 is gone, and a new inflation-adjusted bracket applies in 2027.
