To be clear, no CPAs I interviewed condoned this sort of move. They did explain, however, the keys to understanding how business expenses play out.
"You'd be surprised the benefits you can get from running a business," said Lisa Greene-Lewis, CPA and TurboTax expert. "If you use your car to see clients, you can deduct the mileage or actual expenses for that car. Startup costs, advertising, legal fees, those would be deductible. If you had a dedicated space in your home you use for a home office, you can deduct a portion of mortgage or rent/property taxes."
The easiest method is the simplified option for home office deduction, which allows you to deduct $5 per square foot of home office space, up to 300sqft. That's $1,500. Additionally, any equipment you buy -- computers, phones, printers -- can be deducted.
