The amount of time to keep records differs by type. Some documents and records need to be kept for only a year or a couple of years, while others need to be kept throughout the life of the business. Document retention is very important, but what is the proper length of time to store documents?

Records related to the incorporation of the business should be kept for as long as the business is in operation. Any legal records, such as licenses, patents, registration forms and tax ID forms should also be kept throughout the business’ life.

Tax records have to be kept for a minimum of three years, however, these records may come in handy to your business in the long run so it does not hurt to hold on to them indefinitely. You can safely shred general correspondence, inventory logs and expired insurance policies after three years.

Some records should be kept for seven years. These include bank statements, personnel records for terminated employees and purchase orders.

Here is a list of the different types of documents and the suggested document retention time length:
