Tax season in Canada can be overwhelming, with various forms and documents to navigate. One such essential document is the RC66SCH Form, which plays a crucial role in ensuring that eligible taxpayers receive the benefits they are entitled to. In this blog post, we will explore the significance of the RC66SCH Form, who needs to fill it, and how it can help maximize tax benefits for Canadian taxpayers.

  1. What is the RC66SCH Form?

The RC66SCH Form, also known as the “Canada Child Benefits Application – Schedule RC66SCH,” is a supplementary form to the Canada Child Benefits Application (RC66) used by the Canada Revenue Agency (CRA). It helps determine if additional benefits, such as the Goods and Services Tax/Harmonized Sales Tax (GST/HST) credit and provincial or territorial benefits, can be provided to eligible taxpayers.

  1. Who Needs to Fill the RC66SCH Form?

Canadian families or individuals who have dependent children under the age of 18 and meet certain income criteria may be eligible to receive various child benefits from the government. These benefits can include the Canada Child Benefit (CCB), GST/HST credit, and other provincial or territorial benefits. To apply for these benefits, taxpayers need to complete the RC66SCH Form along with the RC66 Form.

  1. Key Information Required in the RC66SCH Form:

When completing the RC66SCH Form, taxpayers need to provide the following information:

a. Personal information, including name, address, social insurance number (SIN), and date of birth for themselves and their dependents.

b. Details of their marital status and any changes in family composition during the tax year.

c. Total income earned by each family member during the tax year.

d. Information about other government benefits or credits received, if applicable.

  1. Benefits of the RC66SCH Form:

To apply for the benefits mentioned above, taxpayers need to complete the RC66SCH Form and submit it along with the RC66 Form. The application can be submitted by mail or online through the CRA’s My Account portal.


The RC66SCH Form is a valuable tool for Canadian taxpayers with dependent children as it allows them to apply for various benefits that can ease the financial burden of raising a family.
