Accounting records to keep for at least 6 years

For many years, Canadian companies have been required to keep a number of business documents for a period of at least 6 years. The Income Tax Act allows them to keep these records on paper or in digital format. Corporate tax software can be used to keep electronic records.

The documents businesses are required to keep include:

  • Daily income statements with invoices and cash register tapes
  • Daily expense statements with cancelled cheques and expense receipts
  • Travel and company vehicle expense records with supporting documents
  • Company credit card bills
  • Records with the names of employees, their salaries and salary deductions

Companies are required to keep these documents for a period of 6 years. The 6-year period begins at the end of the last tax year the records relate to (e.g., your 2022 tax returns must be kept until 2028 inclusively).

Why keep tax and accounting records for 6 years?

During this period, companies must remain ready and able to supply the Canada Revenue Agency (CRA) and Revenu Québec with any information or documents they request. These agencies may conduct an audit of your T2 or CO-17 tax returns at any time and require proof of your financial dealings.

Companies are also required to keep any and all supporting documents that can be used to verify the information contained in your records, such as company invoices.

Business documents to keep indefinitely

While the retention period for business tax and accounting records is 6 years as a rule, there are other documents that should be kept as long as a company is in business.

Business documents that should be kept indefinitely include the following:

  • Deeds 
  • Board of directors meeting minutes
  • Share certificates and transfers
  • Any other documents that can be used to justify ledger entries

When a corporation is dissolved, the original copies of these documents must be kept for at least two years following the date of dissolution.

Records to keep at the request of government agencies

When determining how long to keep your business records, it is safe to assume that most must be kept for at least 6 years. However, there are certain exceptions that you may be required to keep for longer.

If you are well aware of your tax obligations, you will be prepared in the event that the CRA or Revenu Québec ask to see your records.
