Are you due to pay 28 August provisional tax?
For most business taxpayers, your first instalment of provisional tax for the 2025 tax year is coming up. It’s important to pay what you owe on the due date. Inland Revenue won’t hesitate to charge steep interest and late payment penalties if you don’t.
If you’re a business owner or operator, here are five useful tips to ensure you’re ready to pay the first provisional tax payment for the year on the 28 August due date. For agents, you may also wish to share these tips with your clients to help them prepare.
1. Assess your cashflow
Now’s the time to look at the money coming in and going out of your business.
Cast your eyes over your accounts receivable report to see which customers owe you money. If required, ask them if they can sort their bill earlier. Conversely, see if you can buy more time if you owe suppliers money.
If cashflow is tight or you have a better use for the money, keep reading. There’s an option that lets you pay 28 August provisional tax when it suits you.
2. Be aware of the fish hooks
If you pay less than $60,000, you are what’s known as a safe harbour taxpayer. You won’t be charged interest by Inland Revenue if you pay your provisional tax late. But, you will be charged late payment penalties. You can find out more about safe harbour rules here.
3. Know your methods to calculate 28 August provisional tax
It’s important you are aware of the different methods available to calculate your provisional tax payments. For more information about the provisional tax methods available to you, see our Provisional Tax Guide.
4. Consider using tax pooling

Working with us allows you to pay 28 August provisional tax at a time and in a manner that suits you, without incurring Inland Revenue interest or late payment penalties.
