Businesses can appoint someone else, often a tax professional, to deal with the Canada Revenue Agency (CRA) on their behalf. In order to have online access to tax information about the business, the representative must currently file a Form RC59 with the CRA. The CRA has announced that, after May 15, 2017 Form RC59 will no longer be used to obtain such online access. Instead, the representative will need to carry out the following steps.
It is important for business owners to keep in mind some of the most common errors to avoid getting on the wrong side of the government agencies, and using a business representative can be to you advantage.
