What date does IRS mark as submitted when mailing a tax return for 2025?

Tax pro here - good news! The IRS uses the POSTMARK date as the official submission date for paper returns, not the date they physically receive it. This is why many post offices stay open late on tax day and why you'll see long lines of people trying to get that April 15th postmark! Make sure you: 1) Get proof of mailing - either use certified mail with return receipt or at minimum keep the receipt showing the postmark date 2) Make sure the envelope is properly addressed with correct postage 3) If you're really cutting it close, go inside the post office and have them hand-cancel it with that day's date clearly visible The IRS processing centers are often backed up, especially during peak season, so your return might not be physically processed for weeks after you mail it. But as long as it's postmarked by the filing deadline, you're considered to have filed on time.

I went through this exact situation last year and was freaking out! I found this amazing service called taxr.ai (https://taxr.ai) that helped me figure out my mailing issues and track my return after I sent it. Their document analysis actually helped me understand what would happen after I mailed my return and how the IRS would process it based on my specific situation. I was worried because my return was pretty complex with some small business income and investment stuff, but their system analyzed my documents and explained exactly what would happen at the IRS once they received it. They even helped me understand what to do if the IRS claimed they never received my return (which actually happened to me!).

Okay I need to apologize to Profile 8 because I was super skeptical about taxr.ai but I decided to try it before mailing my return this year. It actually caught that I was missing a form for some crypto transactions I did! Would have completely delayed my processing. The document analysis also showed me that my handwriting on one of my forms was likely to be misread by the IRS scanning system (apparently that's a thing). I rewrote that page before mailing and used their recommended certified mail method with tracking. My return was processed way faster than last year when I had to deal with multiple notices and a processing delay of almost 3 months. I'm usually not one to recommend services but this one actually saved me a lot of headache!

If you're worried about your return being received, you should try Claimyr (https://claimyr.com). Last year I mailed my return and after 3 months, there was still no record of it in the IRS system. I tried calling the IRS for WEEKS but couldn't get through to a human. Claimyr got me connected to an actual IRS agent in about 15 minutes. The agent confirmed they had no record of my return and walked me through what to do next. Check out this video to see how it works: https://youtu.be/_kiP6q8DX5c. Basically they navigate the phone system for you and call you back when they have an agent on the line. Saved me hours of listening to hold music and getting disconnected.

I'm actually embarrassed to be posting this because I was so sure Claimyr was a scam. But after trying to reach the IRS for 2 weeks about my mailed return that seemed to disappear into a black hole, I gave it a shot out of desperation. Within 45 minutes I was talking to an actual IRS representative who confirmed they had received my return but it was placed in the "error resolution" department because of a discrepancy with my withholding amount. The agent was able to verify my correct withholding and move my return out of the error department. Without that call, my return would have been sitting there for potentially months. The IRS never would have notified me until they sent a formal letter weeks later. Not gonna lie, I'm still shocked this service actually worked.

One more thing about mailing returns - if you're sending it close to the deadline, make sure you use the correct address! The IRS has different mailing addresses depending on your state and whether you're enclosing a payment. I sent mine to the wrong processing center once and it added weeks to my processing time. Here's a tip: take a picture of the sealed, addressed envelope with the postage and postmark visible before you drop it in the mail. I've had to prove I mailed something on time before, and having that photo was super helpful.

This is probably a dumb question but does anyone know how long it typically takes for a mailed return to show up in the "Where's My Refund" tool? I mailed mine 3 weeks ago and it still says "Return Not Received" when I check.

Just wanted to add one more important point about the postmark rule - make sure you're using regular USPS mail or an approved private delivery service like FedEx or UPS. I learned the hard way that some local courier services don't count for the postmark rule because they're not IRS-approved delivery services. Also, if you're mailing multiple forms (like your return plus an extension), make sure they're all postmarked by the deadline. I once sent my extension on time but forgot to include a required payment voucher, and had to send that separately. Even though my extension was valid, I still got hit with penalties because the payment was late. One last tip: if you're really stressed about timing, you can actually hand-deliver your return to certain IRS offices, but they have very limited hours and locations for this. Most Taxpayer Assistance Centers stopped accepting returns during COVID and haven't resumed that service. But it's worth checking if you have one nearby and you're cutting it really close!
