IRS Finalizes 2027 Tax Brackets: Married Couples Remain in the 12% Rate Up to $104,050 of Taxable Income

Quick Read

• In 2027, married couples will owe 12% on taxable income up to $104,050; income above that level moves into the 22% bracket.

• A married pair with both spouses age 65 or older may have about $149,000 of adjusted gross income and still remain in the 12% bracket.

• Retirees can use the extra room in the 12% bracket for Roth conversions or additional IRA withdrawals, though Social Security taxation and Medicare surcharges still need attention.

The IRS has issued its inflation adjustments for tax year 2027, revising nearly 70 provisions for returns that will be filed in 2028. For retired married couples, the first number to watch is the point where the 12% bracket ends, since that determines how much income they can realize before taxes rise more sharply.

How the 2027 Brackets Work for Married Couples

For joint filers, the first $25,600 of taxable income is taxed at the lowest rate. Income above that amount is taxed at 12% until taxable income exceeds $104,050. Once that threshold is crossed, the 22% rate applies.

That gives married couples a fairly broad middle band: the 12% bracket covers $78,450 of taxable income. A couple right at the top of that range would owe $11,974 in federal income tax before any credits. Only income above the line is taxed at the higher rate.

Taxable Income Starts After Deductions

Tax brackets apply to taxable income, which is what remains after deductions. Most retired couples do not itemize, so the standard deduction usually does the heavy lifting. For joint filers, it rises to $33,200 in 2027, which is $1,000 more than in 2026.

Older couples get an added benefit. The Working Families Tax Cuts law, which is the IRS label for the 2025 tax package, introduced a senior deduction of $6,000 for each spouse age 65 or older. It remains available for tax years beginning before 2029, so it still applies in 2027.

Married couples may receive $12,000 total if both spouses qualify, according to IRS Publication 554. That deduction is reduced by 6% of modified adjusted gross income above $150,000 on a joint return. Modified adjusted gross income is total income before deductions, with a few items added back.

How Much a 65-Plus Couple Can Earn and Still Stay at 12%

When those figures are combined, the ceiling rises. A couple with both spouses over 65 can have adjusted gross income of $149,250 and still sit at the top of the 12% bracket. That amount includes $104,050 of taxable income, the $33,200 standard deduction, and $12,000 in senior deductions.

That total comes in just below the $150,000 level where the senior deduction begins to phase out, so the full amount still applies. In 2027, each spouse who is 65 or older also qualifies for an additional $1,700 standard deduction. That pushes the couple's potential income ceiling to $152,650, although the senior deduction starts shrinking once modified adjusted gross income exceeds $150,000. For a couple under age 65, the same calculation tops out at $137,250.

Actual cash flow can be higher still. Because part of many retirees' Social Security benefits is excluded from adjusted gross income, a couple may spend more than that ceiling suggests while still keeping taxable income inside the 12% bracket.

Three Ways Retirees Can Put That Space to Work

Roth conversions can fill the gap. If a couple expects taxable income below $104,050, they may be able to move traditional IRA money into a Roth IRA and pay tax on it at 12%. Once that room is used, any additional converted income spills into the 22% bracket. Conversions can also increase the amount of Social Security subject to tax, raising the overall bill. The period after the final paycheck and before required minimum distributions begin is often the least expensive time to convert, which is the focus of our free Roth conversion guide.

Steps to Consider Before Year-End

The new numbers apply to income earned in 2027. Any conversion, withdrawal, or gain realized before December 31, 2026 is still governed by the current year's brackets, and that opportunity disappears at year-end. Our earlier piece on using this year's brackets before they reset explains what to review now.

The Key 2027 Figure for Married Retirees

Keep $104,050 in mind, since that is where the 12% bracket ends for married couples in 2027. For couples in which both spouses are at least 65, the ceiling can climb above $152,000 in adjusted gross income after the extra senior deductions are included, though those deductions begin to phase out above the income threshold. Review every planned conversion, withdrawal, and sale against that limit.
