This time of year, you might be asking yourself, “How should I mail my tax return?”

I’m not a lawyer, an accountant, a financial advisor, or a doctor, but this page at the IRS seems to support the idea that you should send your tax return certified return receipt via the US Post Office:

I used to always get a certificate of mailing because I once thought I heard that was what the IRS recognized, but the above page seems to suggest that might not be good enough if you need to prove you mailed it.

Here’s someone who disagrees, in case you’re looking for justification for just dropping it in the mail and not worrying about it:
