What is a comfort letter?
Not all businesses need a comfort letter. However, you may need one at any point during the life of your business. A comfort letter confirms that a businesses' CRA program accounts are in good standing. It is most commonly requested by financial institutions (lending institutions) and lawyers. This type of letter is different from a request for a clearance certificate. A comfort letter applies to the status of the corporate income tax (RC), payroll deductions (RP), or GST/HST (RT) program accounts. However, it does not apply to GST/HST (RT) program accounts for businesses resident in the province of Quebec.
For example, a bank could request a comfort letter from the CRA for a business before granting a loan. Persons who consider purchasing real property or a business from a person may also request one.
How to request a comfort letter
You must send your request for a comfort letter in writing. Send it either by mail or by fax to the tax services office nearest to the business. Any third party request must be sent with a letter of authorization, unless the requestor is already authorized for each program account.
The request must contain the following information:
- the business number
- the CRA program accounts for which the comfort letter is requested
- the language in which you wish to receive the comfort letter, if different from the language of the request
- the name and position of the person making the request
- a letter of authorization or a completed Form RC59, Business Consent for Access by Telephone and Mail
