Hey! I'm going to assume you live in the US!
Note: I am not a tax accountant, but this is what I've figured.
Keep track of all money you earn from comms and through where if you take payment from multiple sources.
IRS guidelines show that any supplemental income over 600 must be reported as of this tax year (2023).
If you accept payment through PayPal and receive >600 in 2023, you must give them your SSN and legal name so they can file Form 1099-NEC regarding your income to the IRS. You will receive a copy of this form in your email. It will show the total amount earned in 2023. If you accept payment through multiple outlets, you may receive multiple 1099s. Expect to see these by 1/31/24. Save these for your own records! Ideally, you submit these when filing taxes, but it's possible to do so without them.
At the end of the day, the IRS just cares that you're reporting all of your income earned.
