Very good advice from the Hornet. Anyone can set up a business and take Net Operating Losses. However, you have to have legitimate expenses and an ongoing operation. There are restrictions on everything you do. Some start-up costs have to be amortized. You have a certain amount of depreciation for newly purchased equipment that you can write off in the year purchased ( around $20,000 now, I think ), but if you sell any of it in the future, you may have to recapture the depreciation and add it back to income. Any personal use of equipment has to be allocated out of the expense taken. What you're talking about is a good Audit Trigger. And if you are audited, the IRS has great leeway in deciding whether your expenses and business are legitimate. If they determine that your business is not legitimate, not only will you have to pay the back taxes with penalty and interest, they can charge you with fraud. If you don't really have any income.....? How much time are you spending on the "business?" I personally doubt that you would save enough from the maneuver to make it worth raising the eyebrows of the IRS. Especially after you pay the consulting fee for your CPA that you'd better see. Good luck!
