Yes, you still owe income tax after 75 if your income exceeds the threshold

Reaching 75 does not exempt you from filing taxes or paying what you owe. The IRS has no age cutoff for income tax obligations. What changes at 75 is the filing threshold — the amount of income that triggers a requirement to file — and it depends on your filing status and type of income, not your age alone.

If your total income for the year falls below the threshold for your situation, you do not have to file. If it exceeds the threshold, you must file and pay tax on the amount owed, regardless of age. The threshold itself does not change at 75; it has been the same since age 65 and stays the same through your 80s and beyond.

Key Takeaways

  • The filing threshold for people 65 and older is higher than for younger filers, but it does not increase again at 75.
  • You must file if your income exceeds the threshold for your filing status, even if you are retired and over 75.
  • Social Security income counts toward the threshold only if you have other income; if Social Security is your only income, you typically do not file.
  • Required Minimum Distributions (RMDs) from retirement accounts count as taxable income and can push you over the filing threshold.
  • State income tax rules vary and may require filing even when federal tax does not.

What the filing threshold is for people 65 and older

For 2024, if you are single and 65 or older, you must file if your gross income is $15,000 or more. If you are married filing jointly and both spouses are 65 or older, the threshold is $30,000. If only one spouse is 65 or older, it is $29,200. These thresholds apply whether you are 75, 85, or 95 — age 65 is the last time the threshold changes.

Gross income includes wages, self-employment income, interest, dividends, capital gains, and taxable retirement account withdrawals. It does not include certain types of income like municipal bond interest. The threshold is the same whether you work part-time, are fully retired, or receive only investment income.

These numbers change each year for inflation. The IRS publishes updated thresholds in late fall for the following tax year. If you are unsure whether you crossed the threshold, the safest approach is to file anyway — filing when you do not have to does not hurt, and it may result in a refund if taxes were withheld from your income.

How Social Security affects your filing requirement

If Social Security is your only income, you typically do not have to file, even at 75. However, if you have other income — wages, a pension, interest, dividends, or retirement account withdrawals — you must count the taxable portion of your Social Security toward the threshold.

Not all of your Social Security benefit counts as taxable income. The taxable portion depends on your "combined income," which is your adjusted gross income plus nontaxable interest plus half of your Social Security benefit. If your combined income exceeds $25,000 (single) or $32,000 (married filing jointly), up to 85 percent of your benefit may be taxable. This is one reason why people over 75 who thought they were below the threshold sometimes discover they are not.

The IRS sends a form SSA-1099 each January showing your Social Security income. Use that figure, not what you received, when calculating whether you must file.

Required Minimum Distributions and the filing threshold

At age 73 (as of 2023; the age was 72 before that), the IRS requires you to withdraw a set percentage from traditional IRAs, 401(k)s, and similar retirement accounts each year. These Required Minimum Distributions (RMDs) count as taxable income and often push people over the filing threshold, even if they do not need the money.

If your RMD alone exceeds the filing threshold for your status, you must file. For example, a single person over 75 with a $500,000 IRA might owe an RMD of $18,000 or more in a given year — well above the $15,000 threshold. You owe tax on that distribution whether you spend it or reinvest it.

Roth IRA withdrawals do not trigger RMDs during your lifetime, and may have access to Roth distributions are not taxable. If you have the option to convert some traditional IRA funds to a Roth before age 73, doing so can reduce future RMDs and your filing obligation. This is a decision to discuss with a tax professional, as conversions have their own tax consequences in the year you convert.

State income tax requirements for people over 75

Even if you do not owe federal income tax, your state may require you to file. Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividends and interest). In the other 41 states, filing thresholds vary.

Some states tie their threshold to the federal threshold; others set their own, often lower. A few states offer additional exemptions for people over a certain age — typically 65 or older — but these vary widely. New York, for instance, offers a pension exemption for people 59½ and older, which can lower your filing requirement. Illinois exempts all retirement income for people 61 and older.

If you live in a state with income tax, check your state revenue department's website or contact them directly to confirm your filing requirement. Do not assume federal rules apply to your state.

What happens if you do not file when you should

If you owe tax and do not file, the IRS can assess a failure-to-file penalty, which is typically 5 percent of the unpaid tax per month, up to 25 percent. If you owe tax and do not pay, there is also a failure-to-pay penalty of 0.5 percent per month. Interest accrues on top of both penalties, compounding monthly.

If you filed but did not pay in full, the IRS may set up a payment plan. If you cannot pay at all, you can request an offer in compromise or hardship status, though these are difficult to obtain and require documentation of your financial situation. The longer you wait, the more interest and penalties accumulate.

If you simply forgot to file and the IRS has not contacted you, filing now — even years late — stops the clock on penalties and shows good faith. Bring copies of your tax documents and any prior returns you filed. A tax professional or the IRS Volunteer Income Tax Assistance (VITA) program can help you file back returns at no cost if your income is below a certain level.

Frequently Asked Questions

Do I have to file if I am 75 and retired with no income?

No. If you have no income at all, you do not file. If you receive only Social Security and it is below the threshold, you do not file. You only file if your total income — including Social Security, pensions, interest, dividends, and retirement withdrawals — exceeds the threshold for your filing status.

What if I am 75 and still working part-time?

You must file if your total income, including wages plus any other income, exceeds the threshold. Wages count toward the threshold just like any other income. If you earned $16,000 in wages and your filing status threshold is $15,000, you must file.

Can I file even if I do not have to?

Yes. Filing when you do not have to is harmless and often beneficial — if taxes were withheld from your income, you may receive a refund. Filing also protects you from penalties and keeps your Social Security record current.

Does Medicare or Medicaid count as income for tax purposes?

No. Medicare premiums and Medicaid benefits do not count as income. However, if you have other income that triggers a tax filing requirement, you still must file and report that other income.

What if my income varies year to year?

File in any year your income exceeds the threshold. If you have a year with very low income and do not file, that is fine — the IRS only requires filing when the threshold is crossed. Keep records of your income each year so you know whether you crossed it.
