>As someone born in 2003, I did this just last week when filing my tax returns.

Why didn't you efile like a normal person? The only time you need to do it the hard way is if you are under 16 and filing for the first time.

There is a lot of stuff that can make you ineligible for efiling.anything exceptional and not handled by the standard form requires efiling. They only just recently dropped the requirement for 83(b) elections to be sent in with your tax return, and until then I had to send in a paper return every time I did that.

I had to file by mail because I moved to a new state and got 2 W-2s for the same job, of which the W-2 for the former state left the federal fields (1-13) blank. This weird W-2 apparently makes me ineligible for e-file.

Edit: In hindsight, I could have just waited until the start of 2025 to update my address in the HR system and gotten a single, normal W-2, but then I would be both violating the remote work rules (by not adding my new work location) and (probably) committing tax fraud.
