I started a couple of checking accounts to get the sign-up bonuses. This income is reported on a 1099-INT. Can I put the money (up to the contribution maximum, 20% of self-employment earnings) into a SEP IRA?
If yes, what about other types of interest income, like regular interest from bank accounts?
Basically, I can't find the definition anywhere for what qualifies as "self-employment income". Certainly the bank was not my employer when they gave me the sign-up bonus.
