Let me make this very clear – failure to claim money you made as a freelancer is super illegal, and the IRS will figure it out. They can see the money that goes into your account, and if it isn’t all accounted for, an audit will set you back even more than you owe. Please be careful here. You can’t outsmart the IRS by purposefully omitting some money you made. If they find out, you’ll owe even more. This isn’t a gamble that’s worth it in the end.
