A married couple in which both spouses are 65 or older can now subtract as much as $12,000 more from their taxable income for tax years 2025 through 2028, on top of deductions they already claim. The break comes from a temporary “enhanced deduction for seniors” created by last year’s federal tax law, and it does not last indefinitely: it shrinks for higher earners and disappears entirely after the 2028 tax year unless Congress renews it. For a couple planning retirement-account withdrawals or timing a Roth conversion, both the size of the deduction and its four-year clock change the near-term math.
Two $6,000 deductions, one for each spouse
The enhanced deduction is calculated per person rather than per household. Each spouse who turns 65 on or before the last day of the tax year, and who holds a valid Social Security number, can claim the deduction on his or her own. A couple filing jointly reaches the full combined amount only when both spouses meet the age and Social Security number requirements; when just one spouse is 65 or older, the household’s enhanced deduction is half that size.
The Internal Revenue Service puts the deduction at $6,000 for a single eligible senior or up to $12,000 for a qualifying couple, and says it begins to phase out for taxpayers with modified adjusted gross income above $75,000 for single filers or $150,000 for joint filers. The agency also notes the deduction is available to filers who claim the standard deduction as well as those who itemize, a feature that sets it apart from many other write-offs. The IRS’s eligibility guidance lays out the full mechanics.
For a couple near either the $75,000 or $150,000 income line, the deduction is not simply on or off. Modified adjusted gross income for the year, which typically includes IRA and 401(k) withdrawals, Social Security benefits, dividends and other reportable income, determines exactly where the phase-out lands, so the same couple’s deduction can shift from one year to the next based on how much they choose to withdraw or convert.

A second deduction stacked on top of the regular one for seniors
The $6,000 enhancement is separate from, and added to, the additional standard deduction that has applied to filers 65 and older for years under existing law. The Internal Revenue Service describes the new provision explicitly as “in addition to the current additional standard deduction for seniors under existing law,” meaning an eligible retiree now layers two age-based benefits rather than choosing between them. The agency’s 2026 filing-season guidance for seniors confirms the two provisions run side by side.
That older, longstanding add-on is itself adjusted for inflation every year. For tax year 2026, the Internal Revenue Service’s annual inflation-adjustment procedure sets the regular age-65 standard deduction addition at $2,050 for a single filer and $1,650 for each qualifying spouse on a joint return, on top of the base standard deduction. A couple in which both spouses are 65 or older can combine that inflation-indexed add-on with the new $12,000 enhanced deduction on the same return.
Four tax years, then the deduction disappears
The enhanced deduction applies only to tax years 2025 through 2028, and it is claimed on Schedule 1-A rather than folded into the standard deduction total. A married couple must file a joint return to claim it; filing separately disqualifies the couple even if both spouses otherwise meet the age and income tests. The IRS’s own standard-deduction topic page describes the enhanced deduction as distinct from the regular standard deduction and requires the joint-filing Schedule 1-A to claim it.
Nothing in current law extends the deduction past 2028, so a couple building a multi-year withdrawal or Roth-conversion plan around today’s lower taxable income should expect the extra $12,000 to expire on schedule unless a future Congress renews it. The Internal Revenue Service’s own guidance frames the deduction as tied to the tax years already written into the statute, not as an open-ended benefit.
A couple that begins drawing down retirement accounts in 2025 with the enhanced deduction in place could face a noticeably different total tax bill in 2029, once it disappears, than an otherwise identical withdrawal made a year or two earlier while the deduction still applied.
A deduction with an expiration date
Knowing the enhanced deduction only lowers taxable income through 2028 changes how a couple should sequence withdrawals and Roth conversions while the window stays open, and it raises questions the deduction itself does not answer, including how a larger deduction interacts with Medicare’s income-related premium surcharge or the order in which accounts should be tapped. Those calls typically depend on projecting income across several years rather than one.
