With tax season looming large, you may have been thinking about taxes and how having an ecommerce business will affect your status as a taxpayer. Will you have to pay because you're a business owner? Always seek the advice of a qualified accountant to be sure you have the most up-to-date information, but here are some tips on tax write offs that you may not be aware even exist.

Mileage you know about, but are you doing it? You might think you don't need to keep track of your mileage because you make short trips around town to the supplier, the bank, and other necessary trips. Along with mileage, deduct any traveling you do that could be construed as for your business. Those miles add up and at the end of the year, it is a real eye-opener to see how much you can actually write off.

Unpaid invoices are another write-off. If you attempted to collect the money from someone you provided goods or services to and they won't pay you, you can deduct it from your taxes as a loss. You don't have to take the deduction the year it occurred so if you have a number of bad debts around, go ahead and deduct them this year. Be sure to have full documentation of the debt and your attempts to collect.

Your shipping and postage expenses are another often overlooked deduction. When you add up at the end of the year how much you actually spent on shipping your product, you will gladly take that deduction!

Make sure you're getting the proper deductions for your business! Talk to a qualified accountant or visit the IRS website at http://www.irs.gov.
