Bad news first: you can't contribute for the prior tax year after April 15. There's no extension, no exception, no late filing. The window is closed. Better news: the current tax year window is already open — and you can make sure this doesn't happen again.
If you missed the April 15 deadline for the prior tax year, that contribution slot is gone permanently. Unlike most tax items, IRA contributions cannot be backdated. Filing an extension does not help. There is no "oops" form.
The IRS won't send you a bill. There's no penalty. But the contribution limit you didn't use simply expires, and the decades of tax-advantaged growth on that money never happen.
Not a fee. Decades of compounded growth that never gets to start.

The prior year is locked, but you have options for the current tax year. Some you can act on today:
Almost nobody decides to skip an IRA contribution. They decide to do it next week. Then next month. Then after they file their taxes. By the time April 14 rolls around, the bank transfer takes too long to clear and they're locked out.
The window is generous (15.5 months) which paradoxically makes it easier to forget. There's no payroll deduction, no automatic anything. Your brokerage might send one promotional email in March. The IRS doesn't send reminders. Your accountant only flags it at filing time if at all.
The fix isn't more willpower. It's a reliable trigger that fires early enough to leave room for the bank transfer.
The single most effective thing you can do right now is set up a recurring annual reminder. Pick a date in early February. Set it to repeat yearly. You'll get an email with weeks of runway every single year — and follow-up emails if you don't mark it done.
For the exact deadline this year, see the 2026 IRA contribution deadline page. For brokerage cutoff times if you're already in April, see the last-minute IRA contribution guide. Or set up the reminder right here:
Done in seconds. No sign-up required.
No. For Traditional and Roth IRAs, April 15 is firm. Filing a tax extension (Form 4868) extends only your filing deadline to October 15 — it does not extend the IRA contribution deadline. SEP IRAs are the exception: those follow your business tax deadline including extensions.
You cannot contribute for the prior tax year after April 15. The window is closed. You can still contribute for the current tax year going forward — and you should, because the same window will close again 12 months from now if you don't set a reminder.
There's no IRS penalty for not contributing — it's not required. The cost is opportunity cost: the contribution limit you didn't use is gone forever and the compounding growth never happens. For someone 30 years from retirement, a single $7,000 missed contribution is roughly $54,000 in lost retirement income.
Yes. File an amended return (Form 1040-X) to claim the Traditional IRA deduction you missed. You generally have three years from the original filing deadline to amend. Roth contributions are not deductible, so this only applies to Traditional IRAs.
Excess contributions are subject to a 6% per-year penalty until corrected. Withdraw the excess (plus earnings) before the tax filing deadline including extensions to avoid the penalty. The IRS Form 5498 your custodian sends will reflect the corrected amount.
Set a recurring annual reminder for early February — that gives you two months before April 15. Don't rely on your brokerage to remind you; they typically send one promotional email near the deadline that gets filtered to a marketing folder. A dedicated reminder fires reliably and follows up if you don't act.
A free recurring reminder set to fire before April 15, every year. The window will close again. This time, you'll know about it.
