The answer depends on when your business tax is due, and when does the business tax year end. If it has a loss it would be to your advantage to file business first, then personal. However if your business tax year ends after 12/31/2007, then you effectively have no loss for the personal taxes as of yet. If sole proprietor, call it a loss in 07 and take the deduction. Biggest question is what type of business? (Incorporated, Partnership, sole proprietorship, etc.) K-1's, w-2's and 1099's all are in play here. Call an accountant and spend the money.
