You can make GST/HST payments online by using the online banking services of your financial institution, or by using the Canada Revenue Agency My Payment feature. You can pay online with a debit card using Interac Online, preauthorized debit and third-party service providers, as of June 2015.
When using online banking, you make your payments as if you were paying a phone or water bill. To ensure proper credit, be sure to input your social insurance number or business number. Preauthorized debit is a online payment option in which you establish an amount and authorize the Canada Revenue Agency to withdraw it automatically from your bank account on one or more dates. Third-party providers such as TelPay and Plastiq are approved to make GST/HST payments and to charge fees for their services.
