Most taxes are based on historical things (such as the GST return you file, or your income tax bill for your last tax return). If your circumstances change and you’re unable to pay these when due we recommend setting up a payment plan with Inland Revenue to limit the interest and penalties that could be charged for late payment. You can do this yourself through your My IR login, or get in touch with our friendly Support team if you need any assistance.
For forward-looking payments, such as provisional tax, if your circumstances have changed then this can be taken into account when we look at what is due to be paid. This is something you can discuss with our Support team so please get in touch, we’re happy to help!
