The Standard Deduction Changes at 65
One of the few things in the tax code that improves simply because you got older: from the year you turn 65, an additional amount is added to your standard deduction. It applies separately to each spouse who qualifies, it is claimed without any form, and for most retired households it settles the question of whether to itemise at all.
- From the year you turn 65:: You are treated as 65 for the whole year if your birthday falls on or before the first day of the next year.
- Each spouse counts:: A married couple both over 65 claims two additional amounts, not one.
- Blindness adds another:: The additional amount for blindness applies separately and can be claimed alongside the age amount.
- It is automatic:: No election or form is needed. It applies only if you take the standard deduction rather than itemising.
Where the AI summary above gets this wrong
"Everyone gets the same standard deduction for their filing status."
That's surface-true. Here's what it misses:
- Age and blindness each add a separate amount — The base figure for a filing status is only the starting point. Each taxpayer aged 65 or over adds an amount, and each blind taxpayer adds another. A married couple where both are over 65 and one is blind claims three additional amounts on top of the base figure.
- It usually ends the itemising question — The higher deduction makes itemising worth less, and most retired households find that mortgage interest has fallen away, state and local tax is capped, and charitable giving alone does not clear the threshold. That is why giving straight from an IRA matters so much after 70½: it works whether or not you itemise.
- Medical expenses are the exception worth checking — The one category that can still push a retired household over the standard deduction is medical expenses, which must exceed a percentage of adjusted gross income before any of it counts. A year with a long care episode or major dental work can clear it, which makes keeping the receipts worthwhile even in years you expect not to itemise.
01 How the additional amount works
Every filing status has a base standard deduction. On top of that, a taxpayer who is 65 or over at the end of the tax year adds a further amount, and a taxpayer who is blind adds another. The two are independent, so someone who is both claims both.
The age test is generous at the boundary: you are treated as being 65 for the whole tax year if your sixty-fifth birthday falls on or before the first day of the following year. Someone turning 65 on 1 January qualifies for the preceding tax year.
For a married couple filing jointly, each spouse is assessed separately. Two people over 65 claim two additional amounts. Nothing has to be elected or filed — the deduction is simply larger.
Shows: the additional standard deduction available for each spouse aged 65 or over, and again for blindness, on top of the base amount for your filing status. Ignores: whether itemising would produce more, the tax rate the deduction saves at, state deductions, and any separate deduction available to older taxpayers under current law.

02 What it does to the itemising decision
Itemising is only worth doing when the itemised total exceeds the standard deduction, and the additional amounts raise that bar. For most retired households the effect is decisive.
The usual itemised deductions have all shrunk by that stage. The mortgage is frequently repaid, so interest has gone. State and local tax deductions are capped. What is left is charitable giving, which for most households does not clear the threshold on its own.
That has a consequence worth acting on rather than noting. Charitable giving that produces no deduction is giving without a tax benefit, and the two responses are bunching several years into one, or after 70½ giving directly from an IRA where the income never appears on the return at all.

03 The year itemising still wins
Medical expenses are the category that can still tip the balance. They are deductible only above a percentage of adjusted gross income, which is a high floor in an ordinary year and reachable in an unusual one.
A year with a long stay in a care facility, major dental work, or substantial insurance premiums for someone before Medicare can clear it. Long-term care insurance premiums count within age-based limits, and so do many costs that are not obviously medical.
The practical habit is to keep the records regardless. It costs nothing during the year, and the decision on whether to itemise can then be made from actual figures at filing rather than from an assumption made the previous January — the same principle that governs documenting medical spending for other purposes.
This is one of the few pieces of good news in the tax code that arrives automatically, and the reason to know about it is not the deduction itself — it is what it does to charitable giving. Once the standard deduction is unreachable, every cheque written to a charity is worth less than the giver assumes. If you are over 70½ and still writing cheques, move the giving into the IRA and it becomes worth more without giving a dollar more.
FAQ
Do I get a bigger standard deduction at 65?
Yes. An additional amount is added for each taxpayer who is 65 or over at the end of the tax year, and another for each who is blind. A married couple both over 65 claims two additional amounts.
Do I have to claim the additional amount?
No. It applies automatically when you take the standard deduction — there is no election or extra form. It does not apply if you itemise.
Is it still worth itemising after 65?
Usually not, unless medical expenses are large. The higher standard deduction, a repaid mortgage and the cap on state and local tax mean most retired households take the standard deduction.
