Can you deduct startup costs for a business that had no sales until the next year?

Generally, your startup costs are deductible, even if you don’t make sales or turn a profit immediately. However, the time frame for deducting expenses (and the amount you can deduct) can depend on the form of legal entity you have chosen. This really is a tax question, and you should be sure to speak to an accountant who understands small business tax issues.
