Capone failed to submit tax returns at all. Had he filed returns on "legal" income, and covered up the illegal stuff, he probably would never have been convicted.
I'm just not sure putting down that you made 50k killing execs is a good data trail to hand over.
If you are getting paid in certified cred sticks, good luck to the corp trying to trace the money trail anyway. Especially since you likely were doing all your work under various fake SINS.
I understand the play balance for the karma, but the mechanic itself seems wonky.
We can assume two things: 1) If you take a job for the Corp you have the SIN with, they know who you are, and so, you should pay them that
tax income. 2) Your lifestyle expenses and docwagon contracts and any vehicles you drive under your legitimate SIN are known expenses, and,
thus, you can assume that those are values that will be taxed.
We can also guess one thing: Do you want to risk the advantages that come with a SIN for forgetting to pay your taxes? I would believe that any runner is going to have their Fixer launder some of the money for them, so they can have a tax trail of "legitimate" income, and so...they will pay some taxes, just not ALL the taxes they should..
