Written August 24, 2026. All figures verified against IRS.gov on this date and current for the 2025 tax year, filed in spring 2026. Last reviewed August 24, 2026. Tax rules change and the IRS is the final word — this is information, not tax advice.
There was a new tax break for people 65 and older on the return you filed this spring. Six thousand dollars, per person.
You may well have gotten it. If someone else prepared your return, or you used tax software that asked your date of birth, it was probably handled without anyone mentioning it to you by name.
But it’s brand new, it’s temporary, and it lives on a form that didn’t exist a year ago. That combination is exactly how a deduction goes unclaimed by someone entitled to it — and how they never find out.
The good news is that checking takes about two minutes and one piece of paper you already have.
What this changes for you
- Act now: Look at line 13b of your 2025 Form 1040. If it’s blank and you were 65 or older at the end of 2025, that’s worth a closer look — an amended return is possible for three years.
- Watch: The deduction runs for tax years 2025 through 2028 and then ends. Check your paycheck or pension withholding for 2026 if your situation changed.
- Ignore for now: The headlines saying Social Security is now tax-free. This is a deduction against your income, not a change to how benefits are taxed.
- Who’s affected: People who were 65 or older on the last day of the tax year, with a valid Social Security number, whose modified adjusted gross income is under the phase-out thresholds below. Married couples must file jointly.
The short answer
Find your 2025 Form 1040 and look at line 13b. That line is labeled for the total from a new form called Schedule 1-A. If there’s a number on it, the new deductions were claimed. If it’s blank or zero and you were 65 or older on December 31, 2025, it’s worth finding out why.
If you have the Schedule 1-A itself, go one better: look at Part V, line 37. That’s the enhanced deduction for seniors, on its own, with nothing else mixed in.
And if it turns out it was missed, you’re not out of luck. You can file an amended return — Form 1040-X — within three years of filing the original. For a spring 2026 filing, that runs into 2029.
What’s actually happening
For years, being 65 or older got you one thing on your taxes: a slightly larger standard deduction. For 2025 that’s an extra $1,600 per person if you’re married, or $2,000 if you’re single. Useful, quiet, automatic.
The 2025 tax law added something separate on top of that — a flat $6,000 deduction per qualifying person, $12,000 for a married couple where both are 65 or older. It’s often called the senior deduction or the enhanced deduction for seniors.
Two features make it unusual, and both are the reason this post exists.
It doesn’t care whether you itemize. Almost every deduction in American tax law makes you choose: take the standard deduction, or itemize and count up your mortgage interest and charitable giving and medical bills. This one sits outside that choice. You get it either way.
It has its own form. It’s claimed in Part V of Schedule 1-A, a page the IRS created for 2025 to hold four new deductions at once — tips, overtime, car loan interest, and this one. The total from that page lands on line 13b of your 1040 and comes off your taxable income.
Which gives you the one thing worth remembering here:
This is the deduction that isn’t on the main form. It’s on the extra page.
That’s not a complaint about the design so much as a description of the risk. A brand new attachment, in its first year, claiming something no one had ever heard of the year before, is precisely where a return gets filed without it.
What it means for you
A deduction is not a refund. It reduces the amount of income you’re taxed on, and what that’s worth to you depends on your tax bracket.
Rough arithmetic, for one person taking the full $6,000:
| If your top tax rate is | The $6,000 is worth roughly |
|---|---|
| 10% | $600 |
| 12% | $720 |
| 22% | $1,320 |
Double those for a married couple where both spouses are 65 or older and both take the full amount.
And there’s a floor under all of it. If your income was low enough that you owed no federal income tax at all, an extra deduction changes nothing — you can’t reduce a tax bill that was already zero. That’s a real and common situation, and nobody says it out loud. If that’s you, this post costs you two minutes and then you can stop thinking about it.
The income limits
The full amount is available up to $75,000 of modified adjusted gross income, or $150,000 for a couple filing jointly. Above that, it shrinks rather than vanishing.
The form does the shrinking with one line of arithmetic: 6% of every dollar above the threshold comes off the $6,000.
Which means the fade-out is a hundred thousand dollars wide. Six percent of $100,000 is $6,000, so:
- A single filer at $75,000 or under gets the full $6,000. At $175,000 or above, nothing. In between, some of it.
- A couple filing jointly, both 65 or older, at $150,000 or under gets $6,000 each. At $250,000 or above, nothing.
Modified adjusted gross income, for most people, is the same number as the adjusted gross income on line 11 of the 1040. Schedule 1-A works it out for you at the top of the form.
What to do now
Step 1: Find your 2025 return (2 minutes)
You need the copy of the return you filed this spring — the one for tax year 2025.
- If someone prepared it for you, they gave you a copy, usually in a folder or as a PDF by email.
- If you used tax software, sign in to the same account and look for something like “Your tax returns & documents.” Last year’s return is downloadable as a PDF.
- If you can’t find it anywhere, you can get a transcript free from the IRS at irs.gov/individuals/get-transcript. Choose the “Return Transcript” for 2025, which shows the lines as filed. Setting up the account takes longer than the rest of this combined — allow twenty minutes and have your phone handy for the identity check.
Step 2: Look at two lines
On Form 1040 (or 1040-SR), find line 13b. It’s labeled “Additional deductions from Schedule 1-A, line 38,” and it sits directly under line 13a, in the short block between your standard deduction and your taxable income. A number there means Schedule 1-A was filed.
Then find Schedule 1-A itself, if your copy includes it — it’s an attached page titled “Additional Deductions.” Go to Part V, “Enhanced Deduction for Seniors.” The lines run like this:
- Line 36a — your own amount
- Line 36b — your spouse’s amount, if you filed jointly and both of you qualify
- Line 37 — the two added together
What you should see: if you’re single, 65 or older, and comfortably under the income threshold, line 37 reads 6,000. For a couple where both are 65 or older and under the joint threshold, 12,000. A smaller number means the phase-out applied. Zero, or no Schedule 1-A at all, is the case worth investigating.
One thing that trips people up here: the extra standard deduction for age — the $1,600 or $2,000 — is a completely different thing and shows up somewhere else entirely, folded into your standard deduction on line 12. Seeing it there does not mean you got the $6,000.
Step 3: If it looks like it was missed
Before assuming anything, check the four things that would explain a blank line legitimately:
- Age. You had to be born before January 2, 1961 to qualify for tax year 2025. The IRS counts you as 65 on the day before your 65th birthday, which quietly helps anyone born on January 1.
- Social Security number. A valid SSN is required on the return. For a couple, each spouse claiming it needs one.
- Filing status. If you’re married and filed separately, this deduction isn’t available. Filing jointly is required.
- Income. Run the phase-out math above against line 11 of your return.
If none of those explains it, the next step is to ask whoever prepared the return, or to file an amended one yourself.
Filing an amended return: it’s Form 1040-X. Most tax software will let you amend a return you filed through it, electronically, and the IRS accepts e-filed 1040-X forms for recent years. The deadline for claiming a refund is three years after you filed the original, or two years after you paid the tax, whichever is later — so a return filed in spring 2026 has until spring 2029.
If you’d rather have help, it’s free. Two programs prepare returns at no cost, including for people who need something amended:
- IRS VITA and TCE — TCE specializes in taxpayers 60 and older. 800-906-9887.
- AARP Foundation Tax-Aide — 888-227-7669. You don’t need to be an AARP member.
Both run on volunteers and both get busy from January onward. August is an unusually good month to call.
The catch
This is not “no tax on Social Security.” That phrase went around a great deal, including in official-sounding places, and it isn’t what the law did. The rules for how much of your Social Security is taxable are unchanged. What changed is that a deduction was added to your income calculation. For some people the practical effect is that they end up owing nothing — but the benefit isn’t tied to Social Security at all, and you don’t need to be receiving it to get the deduction.
It expires. Tax years 2025, 2026, 2027, 2028. Unless Congress extends it, tax year 2029 goes back to the old arrangement. Worth knowing before you build it into a long-term plan.
A deduction you can’t use is worth nothing. As above — no tax owed, no benefit. There’s no version of this that arrives as a check on its own.
Married filing separately is a real exclusion, not a technicality. Couples who file separately for perfectly good reasons — and there are good reasons — cannot claim this one. If that’s your situation, it’s a genuine trade to look at with someone who can see both returns.
Both spouses have to be 65. The $12,000 figure needs two qualifying people. One spouse 67 and one spouse 62 is a $6,000 household, not $12,000, until the younger one has a birthday.
Amending is not free of effort. A 1040-X is a real filing and it takes the IRS months to process. If the amount at stake is small, that’s a fair thing to weigh. If it’s several hundred dollars or more, it’s your money.
Check your 2026 withholding if something changed. If you turned 65 during 2026, or your income moved near a threshold, the amount being held back from your pension or paycheck may not reflect this. The IRS Tax Withholding Estimator at irs.gov/individuals/tax-withholding-estimator is the tool for that, and doing it in August leaves four months to correct course rather than one.
And the standing caveat for anything in this category: amounts, thresholds and eligibility change, sometimes with little notice. The IRS is the final word, and every figure in this post is linked to its source below.
The bottom line
Go find your 2025 tax return and look at line 13b. That’s the whole check. Everything else in this post is what to do depending on what you see there.
In order:
- Line 13b of Form 1040 — blank or zero is the flag.
- Part V, line 37 of Schedule 1-A — the senior deduction on its own, if you have the page.
- Four legitimate explanations — born after January 1, 1961 · no valid SSN · filed married-separately · income above the phase-out.
- Form 1040-X if it was genuinely missed, any time in the next three years. Or call Tax-Aide at 888-227-7669 and let a volunteer look at it.
The deduction is new, it’s on a page most people have never seen, and it runs out after 2028. Two minutes with a piece of paper you already own is a reasonable price for finding out — and if the answer is “it’s there, line 37, six thousand dollars,” that’s a fine way to spend two minutes too.
