Can I still file my 2025 taxes late?
The IRS accepts late returns year-round. If you’re owed a refund, there’s no penalty at all.
If You’re Owed a Refund
Zero penalty — late-filing penalties only apply to unpaid tax. You have until roughly April 15, 2029 to file a 2025 return and collect your refund. After that, it’s gone for good.
If You Owe
Penalties grow every month, so filing now stops the biggest one (failure-to-file, 5%/month) immediately — even if you can’t pay yet. IRS payment plans are easy to set up online.
How to Actually Do It
Most tax software can still e-file 2025 returns through late 2026. Older years go by mail or through a preparer. Missing W-2s? Your IRS online account has wage transcripts for free.
Several Years Behind?
The IRS generally wants the last 6 years of returns to get back in good standing — and every refund year inside the 3-year window is still claimable.
