Here’s something a lot of first-time filers get wrong — and it’s an expensive mistake to make.
When someone else (usually a parent) claims you as a dependent on their tax return, that’s it. You can’t turn around and claim yourself on your own return for the same year. The IRS system will catch it — especially if you file electronically, which most people do.
What actually happens is this: when two returns are filed for the same tax year and both involve the same Social Security number — once as a dependent on someone else’s return, and once as a self-claimed filer on yours — the IRS sends out a notice. That notice is called a CP87B, and it tells you that you claimed yourself but someone else also claimed you as a dependent. One of those returns is wrong.
If neither side fixes it by filing an amended return, the IRS steps in to figure out who actually gets to claim the dependent. And that process? It’s an audit. You’ll get a letter, and then you wait — potentially months — while they sort it out. Your refund sits frozen the whole time.
So before you file, have a real conversation with whoever does your parents’ taxes. Ask them: are you claiming me this year? If yes, you don’t claim yourself. Simple as that. It might feel weird to ask, but it’s way less weird than explaining a tax audit.
And just to be clear — a dependent can’t claim a dependent on their own return either. So if you’re someone else’s dependent, that affects a few things on your own filing, not just the self-exemption piece.
If you’re unsure whether you qualify as someone’s dependent in the first place, the IRS has rules for that — it comes down to things like age, where you live, and whether someone else is paying most of your expenses. When in doubt, check before you file. A five-minute conversation saves a months-long headache.
