2026 Tax Deadlines for Federal Retirees: Complete Timeline

Last Updated: April 5, 2026 Reading Time: 7 min

If you retired from federal service, tax season means tracking more forms than most people ever deal with. There's your OPM pension, a possible TSP withdrawal, Social Security, maybe a part-time job. Each one has its own 1099, its own deadlines, its own penalty structure.

April 15 is 10 days away. Here are all the dates you need, in one place.

Key Takeaways

• April 15, 2026 is the primary filing deadline and the last day to make 2025 IRA contributions
• OPM 1099-Rs were delayed in 2026 due to a policy change. If you have not received yours, log in to Retirement Services Online at OPM.gov
• First RMD for those born in 1952 was due April 1, 2026. Annual RMDs must be taken by December 31 each year
• Four quarterly estimated payment dates: April 15, June 16, September 15, and January 15, 2027
• IRA contributions cannot be extended even if you file a tax extension
• Roth TSP is exempt from RMDs under SECURE 2.0

Federal Tax Filing Deadlines

The Main Deadlines

Deadline	Date	What It Covers
File 2025 return or extension	April 15, 2026	Individual income tax return
Pay any tax owed	April 15, 2026	Cannot be extended
File extended return	October 15, 2026	If Form 4868 was filed by April 15

Extension rules: Filing Form 4868 by April 15 gives you until October 15 to submit your return. It does not give you more time to pay. If you owe taxes, estimate the amount and pay by April 15 to avoid penalties and interest.

Penalty for not filing: 5% of unpaid taxes per month, up to 25% total.

Penalty for not paying: 0.5% of unpaid taxes per month, up to 25% total. Much smaller than the failure-to-file penalty, so file on time even if you cannot pay in full.

Who Qualifies for an Automatic Extension

Certain taxpayers get automatic deadline extensions without filing Form 4868:

• Disaster area residents: Check IRS.gov for current disaster declarations by state
• Overseas taxpayers: U.S. citizens living abroad get until June 15 to file, though interest still accrues on any tax owed after April 15

For most federal retirees, April 15 is the deadline.

When Your 1099-R Forms Arrive

You need your 1099-R forms before you can file. Federal retirees typically receive two: one from OPM for your pension and one from TSP if you took any distributions.

OPM 1099-R (Your Federal Pension)

Milestone	2026 Timeline
Standard mailing deadline	January 31, 2026
Online access (Retirement Services Online)	January 31, 2026
2026 paper form delays	Many retirees received forms in mid-to-late March

What happened in 2026: OPM changed its policy. Annuitants with an email address on file received digital-only 1099-Rs. Retirees who wanted paper copies had to log in to Retirement Services Online and update their preferences. The change caused widespread delays, with many retirees not receiving paper forms until mid-March, and Congress formally asked OPM to explain the delays.

If you still have not received your OPM 1099-R: Log in to Retirement Services Online at servicesonline.opm.gov or call OPM at 1-888-767-6738.

What the form shows: Your gross pension payments (Box 1) and the taxable portion (Box 2a). For FERS retirees, roughly 95% is taxable. For CSRS retirees, your taxable percentage depends on your total contributions and life expectancy.

TSP 1099-R (Your Thrift Savings Plan)

Milestone	2026 Timeline
Paper forms mailed	Mid-January 2026
Online access in My Account	Mid-February 2026
Corrected forms (if needed)	Late February or early March 2026

You only receive a TSP 1099-R if you took a distribution, withdrawal, or had a loan taxed as a distribution in 2025. If you left your money in TSP without touching it, no 1099-R is issued.

Cutoff note: Withdrawals requested after noon Eastern on December 27, 2025 count as 2026 income. They will appear on your 2026 1099-R, not your 2025 form.

For more detail on reading your TSP 1099-R, see our TSP 1099-R Tax Guide and TSP 1099-R Mailing Schedule.

SSA-1099 (Your Social Security Benefits)

The Social Security Administration mails SSA-1099 forms by January 31 each year. You can also access yours at SSA.gov. This form shows your total 2025 Social Security benefits, which you need to calculate how much is taxable.

Federal retiree reality: Most FERS retirees collecting a pension plus Social Security will have combined income well above the $34,000 threshold (single) or $44,000 threshold (married filing jointly). That means up to 85% of your Social Security is taxable.

Quarterly Estimated Tax Payments

If you do not have enough withheld from your pension and TSP, you owe quarterly estimated taxes. Federal retirees with a pension, TSP, and Social Security frequently find their withholding falls short.

2026 Quarterly Due Dates

Quarter	Income Covered	Due Date
Q1	January - March 2026	April 15, 2026
Q2	April - May 2026	June 16, 2026
Q3	June - August 2026	September 15, 2026
Q4	September - December 2026	January 15, 2027

June 16 instead of June 15: the standard Q2 date falls on a Sunday in 2026, so the deadline shifts to Monday.

You need to make estimated payments if you expect to owe at least $1,000 after withholding and credits. OPM pension withholding and TSP default withholding often leave a gap, especially once Social Security is in the mix.

Safe harbor rule: You avoid underpayment penalties if you pay at least 100% of last year's tax liability through withholding and estimated payments (110% if your prior-year AGI exceeded $150,000).

How to adjust withholding instead: You can request additional withholding from your OPM pension using Form W-4P. For TSP withdrawals, adjust withholding through your My Account at TSP.gov. This can reduce or eliminate the need for separate quarterly payments.

How to pay: Use IRS Direct Pay at irs.gov, the Electronic Federal Tax Payment System (EFTPS), or mail a check with Form 1040-ES.

IRA and Roth IRA Contribution Deadlines

2025 Contributions (Due April 15, 2026)

You can still make IRA contributions for the 2025 tax year up until April 15, 2026.

Account Type	2025 Limit (Under 50)	2025 Limit (50+)
Traditional IRA	$7,000	$8,000
Roth IRA	$7,000	$8,000
Combined (both accounts)	$7,000	$8,000

Critical rule: This deadline is April 15, 2026 and cannot be extended. Even if you file for a tax extension, your IRA contribution for 2025 must be made by April 15.

Traditional IRA deductibility: If you or your spouse are covered by a workplace retirement plan (which includes FERS and TSP), your ability to deduct Traditional IRA contributions phases out based on income. For 2025, single filers covered by a workplace plan phase out between $79,000 and $89,000. Married filing jointly phases out between $126,000 and $146,000.

Roth IRA income limits for 2025: Single filers phase out between $150,000 and $165,000. Married filing jointly phases out between $236,000 and $246,000.

2026 Contributions (Can Start Now, Due April 15, 2027)

You can start making 2026 IRA contributions any time after January 1, 2026.

Account Type	2026 Limit (Under 50)	2026 Limit (50+)
Traditional IRA	$7,500	$8,600
Roth IRA	$7,500	$8,600

Required Minimum Distribution (RMD) Deadlines

RMDs are mandatory withdrawals from Traditional TSP, Traditional IRA, and other pre-tax retirement accounts. Skipping them triggers a 25% excise tax on the missed amount.

When RMDs Begin

Birth Year	RMD Start Age	Notes
1950 or earlier	72 (already in RMD)	RMDs ongoing
1951 - 1959	73	SECURE 2.0 rules
1960 or later	75	SECURE 2.0 rules

The First-RMD Special Rule (April 1 Deadline)

Your first-ever RMD does not have to be taken by December 31 of the year you turn 73 (or 75). You can delay it until April 1 of the following year.

2026 example: If you were born in 1952 and turned 73 in 2025, your first RMD was due by April 1, 2026. If you waited until April 1, you now must also take your 2026 RMD by December 31, 2026. That means two RMDs in 2026, which could push you into a higher tax bracket. In most cases, it is smarter to take the first RMD in the year you turn 73 to avoid doubling up.

Annual RMD Deadlines

After your first RMD, all subsequent RMDs must be taken by December 31 each year.

Date	What Happens
April 1, 2026	First RMD due for those who turned 73 in 2025
December 31, 2026	Annual RMD due for all others in RMD phase

Roth TSP Exception

Under SECURE 2.0, Roth TSP accounts are no longer subject to RMDs. If your balance is in Roth TSP, you do not need to take distributions based on age. Roth IRAs have never been subject to RMDs during the original owner's lifetime.

Traditional TSP accounts are still subject to RMDs.

Penalty for Missing an RMD

The IRS charges a 25% excise tax on the amount you should have withdrawn but did not. This drops to 10% if you correct the missed RMD within a two-year correction window.

Example: If your 2026 RMD is $20,000 and you miss it, you owe $5,000 in excise taxes. Correct it within two years and the penalty drops to $2,000.

State Tax Deadlines

Most states follow the federal April 15 deadline. A few exceptions:

State	Filing Deadline	Notes
Most states	April 15, 2026	Follows federal deadline
Virginia	May 1, 2026	Standard Virginia deadline
Delaware	April 30, 2026	Standard Delaware deadline
Iowa	April 30, 2026	Standard Iowa deadline
Hawaii	April 20, 2026	Standard Hawaii deadline
Louisiana	May 15, 2026	Follows one month behind federal

Always verify your state deadline at your state's department of revenue website. States also have their own extension rules that may differ from federal.

Nine states have no income tax. Several others exempt federal pensions entirely. See our Tax Planning for Federal Retirees guide for a full state-by-state breakdown.

What To Do If You Are Late

You Missed the April 15 Filing Deadline

File as soon as possible. The failure-to-file penalty (5% per month) is 10 times larger than the failure-to-pay penalty (0.5% per month). Filing late is always better than not filing at all.

If you owe taxes, pay what you can now. The IRS charges interest on any unpaid balance starting April 16. Partial payments reduce your interest burden.

If you cannot pay in full, the IRS has options. An installment agreement lets you pay monthly. If you are in genuine financial hardship, you can request "currently not collectible" status. If you owe significantly more than you can ever reasonably pay, an Offer in Compromise may let you settle for less.

You Missed an Estimated Payment

Pay as soon as you realize it. The underpayment penalty applies from the due date of the missed payment, not from when you catch the mistake. The sooner you pay, the less you owe in penalties.

You Missed Your RMD

Withdraw the required amount immediately and file Form 5329 with your tax return to report the missed RMD. You can request a penalty waiver by checking Box C on Form 5329 if the missed RMD was due to reasonable error. The IRS has historically granted waivers for first-time mistakes.

You Need a Corrected 1099-R

If your OPM or TSP 1099-R has an error, do not file using the incorrect form. Contact OPM or TSP directly to request a corrected form. Corrected forms are typically issued within three weeks. Filing an amended return after the fact creates more work and potential delays in any refund.

Calculate Your TSP Strategy

Use the free TSP Calculator to project your balance and model different withdrawal timelines. Taking larger withdrawals now in a low-bracket year, for example, can shrink the RMDs you are forced to take at 73 or 75.

Frequently Asked Questions

When is the 2026 tax filing deadline for federal retirees?

April 15, 2026. This applies to all taxpayers, including federal retirees. If you need more time to file, request an extension by April 15, which pushes your filing deadline to October 15, 2026. An extension does not extend your time to pay any taxes owed.

When does OPM send 1099-R forms to federal retirees?

OPM's standard deadline is January 31 each year. In 2026, many retirees experienced significant delays due to OPM's new policy of sending digital-only forms to annuitants with email addresses on file. Paper forms for those who requested them were mailed in mid-March 2026 with receipt expected by March 18.

Do I have to take an RMD in 2026?

It depends on your birth year. If you were born in 1952, your first RMD was due by April 1, 2026. If you were born in 1951-1959, annual RMDs are due by December 31, 2026. If you were born in 1960 or later, RMDs begin at age 75. Roth TSP accounts are exempt from RMDs under SECURE 2.0.

Can I still make an IRA contribution for the 2025 tax year?

Yes, if you have not filed your 2025 taxes yet. The deadline for 2025 IRA contributions is April 15, 2026. You can contribute up to $7,000 ($8,000 if age 50 or older) for 2025. This deadline cannot be extended even if you file for a filing extension.

What are the quarterly estimated tax payment dates for 2026?

The four quarterly due dates are: April 15 (Q1), June 16 (Q2, since June 15 is a Sunday), September 15 (Q3), and January 15, 2027 (Q4). Most federal retirees need to make estimated payments if their pension, TSP, or Social Security withholding is insufficient.

What is the penalty for missing an RMD deadline?

The IRS charges a 25% excise tax on the amount you should have withdrawn but did not. This drops to 10% if you correct the missed RMD within two years. There is no penalty for Roth TSP accounts, which are not subject to RMDs.
