Federal tax guide for older adults
Last updated: 16 September 2026
If you are dealing with taxes in 2026, first identify which tax year you are working on. Most people filing a return now are finishing a 2025 federal return. Planning for income you receive during 2026 uses a different set of annual amounts.
Bottom Line
If you filed a valid extension for your 2025 federal return, October 15, 2026 is the main deadline to watch. An extension gave more time to file, not more time to pay. Seniors should also check both age-based deductions, Social Security tax rules, Required Minimum Distributions (RMDs), and any IRS notice before filing. The IRS filing deadlines page has the current federal dates.
Start Here
- Confirm the tax year. A return filed in 2026 is usually for tax year 2025.
- Check your status. If you filed an extension, finish the return before October 15. If you did not file or extend, file as soon as you can.
- Gather retirement forms. Find every Form SSA-1099, 1099-R, bank or brokerage form, and any IRS notice before you send the return.
| Your situation | Best first step | Main risk |
|---|---|---|
| Valid 2025 extension | Finish the return before October 15, 2026 | Waiting until the final days for missing forms |
| No return or extension | File as soon as possible | Growing penalties and interest if tax is owed |
| Possible missed RMD | Contact the account custodian and review Form 5329 | Excise tax on the shortfall |
| IRS notice | Read the response date and gather records | Missing a notice deadline |
What Has Changed
Since this guide was last reviewed in May, the main change is timing. The regular April filing season is over, and the October 15 extension deadline is now close. AARP Tax-Aide also lists its 2026 tax-season service as closed, so late filers may need IRS Free File, a year-round local VITA/TCE site, or a paid preparer.
The core 2025 senior tax rules checked for this update have not been rolled back. The enhanced senior deduction remains up to $6,000 per eligible person for 2025 through 2028, and the 2025 state and local tax deduction limit remains higher than under prior law. For broader context on the legislation, see our new tax law overview.
Use the Right Tax Year
Tax years cause many avoidable mistakes. A federal return filed during 2026 usually reports income received during 2025. That means you should use 2025 forms and 2025 deduction amounts. The IRS says the regular deadline for most 2025 calendar-year returns was April 15, 2026.
If you requested a valid six-month extension by the original deadline, you generally have until October 15, 2026 to file. The extension did not delay the April payment deadline. The IRS explains that unpaid tax can continue to collect penalties and interest. If you still owe, use the IRS payment options instead of waiting to file.
If you expect a refund, filing promptly helps you receive it sooner and gives you more time to fix a missing-document problem before the year ends.
For planning income received in 2026, use 2026 figures. The IRS has already published its 2026 inflation adjustments, including a standard deduction of $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household. These 2026 amounts normally apply to returns filed in 2027.
| Filing status | 2025 standard deduction | 2025 age-65 add-on | 2026 standard deduction |
|---|---|---|---|
| Single | $15,750 | $2,000 | $16,100 |
| Head of household | $23,625 | $2,000 | $24,150 |
| Married filing jointly | $31,500 | $1,600 per eligible spouse | $32,200 |
The age-65 add-on shown above is part of the standard deduction and applies only when you do not itemize. The IRS explains these rules in Publication 554.
Check Both Senior Deductions
Two different age-based deductions now matter. They are easy to confuse.
The regular age-65 addition
If you take the standard deduction and were age 65 or older at the end of 2025, you may get an extra standard deduction. For 2025, that extra amount is $2,000 for an unmarried taxpayer who is single or head of household, and $1,600 for each eligible married taxpayer or qualifying surviving spouse. The standard deduction is not available in every situation, such as when a married-filing-separately spouse itemizes.
The enhanced senior deduction
The newer enhanced deduction is separate. For tax years 2025 through 2028, an eligible person age 65 or older may claim up to $6,000. A married couple filing jointly may claim up to $12,000 if both spouses qualify. The deduction begins to phase down when modified adjusted gross income is above $75,000 for an individual or $150,000 on a joint return.
This newer deduction can be available whether you take the standard deduction or itemize. Married taxpayers generally must file jointly to claim it, and each person claiming it must have a valid Social Security number. The IRS uses Schedule 1-A for the calculation. Our tax help for seniors guide explains where to get filing assistance.
Itemizing may deserve another look
For 2025, the federal limit on the deduction for state and local income, sales, and property taxes rose to $40,000, or $20,000 for married filing separately. The limit can be reduced at higher income levels. The Schedule A instructions explain the calculation. This change may matter to homeowners who previously stopped itemizing because of the old lower cap.
Property-tax relief offered by a state or county is a separate issue from the federal itemized deduction. For local homeowner programs, use our property-tax relief by state guide.
Social Security and Retirement Income
The enhanced senior deduction did not repeal federal tax rules for Social Security. Benefits may still be taxable when other income is added. For 2025, the IRS senior tax guide continues to use base amounts that start at $25,000 for many single filers and $32,000 for married couples filing jointly when determining whether benefits may become taxable. In some cases, up to 85% of benefits can be included in taxable income.
Use the IRS benefits tax tool for a case-specific check. Our Social Security tax guide gives a simpler walkthrough of how pensions, IRA withdrawals, and other income interact with benefits.
Pensions, traditional IRA withdrawals, 401(k) distributions, interest, dividends, and capital gains can all affect the return. A Form 1099-R should be matched to the return. If a taxpayer made nondeductible IRA contributions in earlier years, old basis records can also matter because not every dollar of a later distribution is necessarily taxable.
RMDs and IRA Withdrawals
Most people subject to Required Minimum Distributions begin at age 73 under current federal rules. The first RMD can sometimes be delayed until April 1 of the following year, but delaying it can put two taxable RMDs in the same calendar year. The IRS RMD rules explain the timing.
A missed RMD is one of the highest-risk issues in this guide. The additional tax is generally 25% of the amount that should have been distributed. It may be reduced to 10% when the shortfall is corrected in time under IRS rules. The taxpayer should take the missing amount promptly, calculate the shortfall carefully, and review Form 5329 instructions. The IRS can waive the tax in some reasonable-error cases when corrective steps are being taken.
Reality check: Do not assume the IRA custodian is legally responsible for every RMD decision. The taxpayer remains responsible for meeting the federal requirement.
A Qualified Charitable Distribution (QCD) can count toward an RMD when done correctly. For 2025, the annual QCD exclusion limit is $108,000. For 2026, it rises to $111,000. The transfer must generally go directly from the IRA trustee to an eligible charity. See Publication 590-B before using this strategy.
Credits Seniors May Miss
Credit for the Elderly or Disabled
This federal credit is available only to a narrow group. A person may qualify if age 65 or older, or under 65 and retired on permanent and total disability, and income stays below the program limits. For 2025, the IRS applies both an adjusted gross income limit and a separate limit for certain nontaxable Social Security, pension, annuity, or disability income. Use the Schedule R instructions for the actual test. Our elderly or disabled credit guide explains the screening rules.
Earned Income Tax Credit
The Earned Income Tax Credit (EITC) is based on earned income, not retirement income. Age rules also differ depending on whether the taxpayer has a qualifying child. For 2025, Publication 596 says a person claiming EITC without a qualifying child generally must be at least 25 but under 65. An older worker with a qualifying child may still qualify if the other rules are met. Check the IRS EITC tables and our senior EITC guide.
Filing, Payment, and Free Help
If your 2025 return is still unfinished, choose help based on complexity. A simple return with Social Security, a pension, bank interest, and ordinary deductions may not need an expensive preparer. A missed RMD, inherited IRA, old after-tax basis, multi-state issue, or serious IRS notice can justify professional help.
| Need | Good starting point | Important limit |
|---|---|---|
| Free online filing | IRS Free File | Guided filing lists a 2025 AGI limit of $89,000 |
| Volunteer tax preparation | VITA and TCE | Sites and services vary; many are seasonal |
| Pay tax over time | IRS payment plan options | Interest and penalties can continue |
| Complex retirement issue | EA, CPA, or tax attorney | Ask about direct experience with the issue |
Free volunteer help can be harder to find after the main filing season. Call before traveling to a site. If the return is complex, check a paid preparer’s credentials and experience instead of choosing only by price.
Documents to Gather
- Last year’s federal and state returns.
- Form SSA-1099 or Railroad Retirement benefit statements.
- Every Form 1099-R for pensions, annuities, IRAs, and workplace plans.
- Forms 1099-INT, 1099-DIV, and 1099-B from financial accounts.
- Year-end IRA and retirement-plan statements for RMD review.
- Records of estimated payments and tax withholding.
- Medical, charitable, property-tax, and mortgage-interest records if itemizing may help.
- Any IRS notice, including its response date.
- Old Form 8606 records if nondeductible IRA contributions may exist.
How to Start Without Wasting Time
- Sort papers by type. Keep Social Security, retirement, bank, brokerage, deductions, and IRS notices in separate groups.
- Confirm filing status. Marriage, divorce, widowhood, and a spouse’s death can change deduction amounts and tax results.
- Match every income form. Missing a 1099-R or brokerage form can lead to an IRS mismatch notice.
- Check age deductions separately. The regular age-65 standard-deduction addition and the enhanced senior deduction are different rules.
- Review RMDs before filing. Fix a possible shortfall before it becomes harder to document.
- Keep proof. Save the filed return, electronic confirmation, payment confirmation, and all notices.
Reality Checks
- An extension is not extra payment time. Tax due for most 2025 returns was still due April 15, 2026.
- The senior deduction is not automatic. Age, filing status, Social Security number, and income rules still apply.
- Social Security is not automatically tax-free. Other income can make part of the benefit taxable.
- Free help is seasonal. AARP Tax-Aide is closed for the 2026 season, and VITA/TCE availability varies by site.
- State rules are separate. Pension, Social Security, property-tax, and retirement-income rules differ by state. See our 2026 tax guides for North Carolina, Rhode Island, and Virginia for state-specific details.
Common Mistakes to Avoid
- Using 2026 planning numbers on a 2025 return.
- Confusing the regular age-65 standard-deduction addition with the enhanced senior deduction.
- Assuming the enhanced senior deduction made Social Security federally tax-free.
- Ignoring an RMD because the bank did not send a strong reminder.
- Filing before all 1099-R and brokerage forms arrive.
- Ignoring an IRS notice because the amount shown seems wrong.
- Changing a return based on a phone call without keeping written records.
If You Get a Notice, Delay, or Tax Problem
Read the whole notice before responding. A CP2000, for example, proposes changes based on information the IRS received; it is not automatically a final bill. The CP2000 guide explains how to agree or disagree.
If the issue is causing financial hardship, or normal IRS channels are not fixing a serious problem, the independent Taxpayer Advocate Service may be able to help. Keep copies of the notice, prior responses, proof of mailing, and notes from calls.
If an adult child or caregiver needs to talk with the IRS for a parent, authorization may be required. Form 2848 can authorize an eligible representative, while Form 8821 can authorize access to tax information without giving representation authority.
If tax questions are only one part of a larger financial problem, our senior help tools can route you to other benefit and household-cost resources.
Phone Scripts
Calling an IRA custodian about an RMD
“I need to confirm whether I had a Required Minimum Distribution for 2025. What amount was required, what amount was distributed, and do your records show a shortfall?”
Calling about an IRS notice
“I received notice number [number]. I want to understand what information the IRS says is different and what documents I should send before the response date.”
Calling a free tax site
“Are you still preparing 2025 returns after the regular filing season? I am age [age] and my return includes [Social Security/pension/IRA]. What should I bring?”
Calling a paid preparer
“Do you regularly handle senior returns with RMDs, inherited IRAs, Social Security taxation, or IRS notices? Who will sign the return, and how is your fee set?”
Resumen en Español
Si presenta una declaración federal en 2026, normalmente está terminando la declaración del año tributario 2025. Si pidió una prórroga válida, la fecha principal para presentar es el 15 de octubre de 2026. La prórroga no dio más tiempo para pagar.
Las personas de 65 años o más deben revisar dos reglas distintas: la deducción adicional normal por edad cuando usan la deducción estándar, y la nueva deducción mejorada para personas mayores de hasta $6,000 por persona elegible. La nueva deducción no eliminó las reglas federales que pueden hacer tributable una parte del Seguro Social.
Si faltó una Distribución Mínima Requerida (RMD), contacte pronto al administrador de la cuenta y revise el Formulario 5329. Si recibió una carta del IRS, lea la fecha límite y guarde copias de todo. Para ayuda gratuita, revise IRS Free File y los sitios VITA/TCE; la disponibilidad local puede ser limitada fuera de la temporada principal.
Frequently Asked Questions
Am I filing 2025 or 2026 taxes?
A return filed in 2026 is usually for tax year 2025. Use 2025 forms and 2025 deduction amounts for that return. Use 2026 amounts mainly to plan income received during 2026 and a return filed in 2027.
What if I filed an extension?
A valid federal extension generally gives a calendar-year filer until October 15, 2026 to file the 2025 return. It did not extend the April 15 payment deadline.
Can seniors claim both deductions?
Some can. The regular age-65 addition is part of the standard deduction and does not apply when you itemize. The enhanced senior deduction is separate and can be available to eligible taxpayers who use the standard deduction or itemize.
Is Social Security tax-free now?
No. The enhanced senior deduction did not repeal the federal rules for taxing Social Security. Other income can still make part of a person’s benefits taxable.
What if I missed an RMD?
Take the possible shortfall seriously. The additional tax is generally 25% of the amount not distributed and may be reduced to 10% when corrected in time under IRS rules. Review Form 5329 and consider professional help.
Where can seniors get free tax help?
IRS Free File can help eligible online filers, and VITA/TCE sites provide free preparation for qualifying taxpayers. Many volunteer sites are seasonal, and AARP Tax-Aide lists its 2026 tax-season service as closed.
