it's just an extremely bad idea for him to make monthly gifts to you from the business account. even if he doesn't deduct the payments, they would look mighty suspicious if the business was audited. it could appear to the auditor that he's paying you compensation because of the regularity of the payments. he's just not paying the payroll taxes and not reporting it. this could present you with tax problems. if he asks you to fill out a W-9 then he's treating them as a business expense and you should expect a 1099. that too is likely wrong - as an employee, you should get a w-2.
