Self employed

@Renigma   Yes you have to report all  your income no matter how small.  Even $1 of bank interest you don't get a 1099 for.    If you have self employment you need to report it even if under $600.  You have to pay the self employment tax on $433 or more.  What if 20 people paid you $500 so you didn't get any 1099NEC forms.  That would be $10,000.  Or if someone didn't send you the 1099NEC for over $600?  You need to keep your own good records.   There are many reasons to report all your SE income.   The Net Profit on Schedule C can count as Earned Income to qualify for credits and IRA deductions.  And you might be able to write off medical premiums without using schedule A for itemized deductions.
