Will my bank let me pay taxes online?

How do I make sure my tax payments get to the ministry on time?

Ask your bank or financial institution when you need to pay your taxes to meet the ministry's payment deadlines. For example, you may be late if you submit tax payments in the afternoon or early evening of the due date. It just may not be enough time for your bank to process your request. Note: if the due date falls on a weekend or holiday, you must pay your taxes on the next banking day.
