Tax Tips - How long should I keep tax records?
Keep copies of your tax returns for at least 6 years or longer. Most people don't need to worry about tax fraud investigations and unreported income but you should keep a copy of your return, particularly if you enlist the help of a tax professional. Your previous tax returns will help you to see trends in your income taxes to better prepare for your future tax returns. If you switch tax preparers it is beneficial for them to review previous years to determine whether any credits or deductions that where missed or need to be carried forward from previous years.
