What you need to know about filing your Sales Tax

Why filing GST/HST matters

Goods and Services Tax (GST) and Harmonized Sales Tax (HST) apply to most goods and services sold in Canada. Failure to file or misreport can result in penalties, interest, and audits. Proper filing ensures that input tax credits are claimed, refunds are received promptly, and the business stays fully compliant with CRA regulations.

Essential for corporations who charge GST/HST

GST/HST filing services are essential for corporations, sole proprietors, and partnerships operating in Canada. This includes small businesses in Toronto, Mississauga, Brampton, and the broader GTA, as well as non-resident businesses providing goods or services to Canadian customers.

Paying HST/GST can be a headache, but not for us

The filing process involves calculating taxable revenues, applying the correct GST or HST rates, claiming eligible input tax credits, and submitting the return to the CRA. At C.A.T.S Accounting, we take care of all the hard stuff, so you can rest easy knowing your payments are accurate and on time.
