Accounting firms and Certified Public Accountants (CPAs) deal with numerous financial documents, and many of those records need to be carefully maintained. While federal law requires you to keep tax documents and supporting records for three years, the IRS may audit records up to six years back in certain cases, so it’s important to keep that in mind when creating a record retention policy.

In addition, some records are best kept indefinitely while others can be cycled out after a year. Here, we’ll take a look at how long most records need to be maintained.
