Frequently Asked Questions
How do I know if I can pay my invoice online?
All invoices—electronic or paper—can be paid online. However, only electronic invoices delivered on or after March 25, 2026, can be viewed in PDF form in the portal. Invoices sent with tax return delivery can also be paid online but are not available for preview.
What payment methods are accepted?
You can use a bank transfer, a credit card or a debit card to pay your invoice. You can also set up automatic and recurring payments.
Does it cost anything extra to pay via the portal?
If you pay via a bank transfer or debit card, there is no fee. Payments made with a credit card will incur a 3.5% processing fee.
Do I have to set up an account?
An account is not required, but having an account gives you more convenient options, like recurring payments, stored payment methods, and managing all invoices associated with a single email address at once.
