Someone who examine your facts and circumstances and advise you on tax entity structuring and treatment of payments/expenses.If the washing business is a disregarded entity, there would be no deduction as you're just moving money "from one pocket to the other".If an S Corp or C Corp, possibly, but then we'd have to look at: is the payment reasonable, ordinary and necessary.
