Provisional Tax Reminder

October 2025

  • October 16, 2025

The next provisional tax instalment date is 28 October 2025.

Provisional taxpayers with the below balance dates will generally have a tax instalment due on 28 October 2025.

  • 31 May balance date – first provisional tax instalment for the 2026 tax year.
  • 31 January balance date – second provisional tax instalment for the 2026 tax year.
  • 30 September balance date – third provisional tax instalment for the 2025 tax year.

Taxpayers who pay their GST 6-monthly and have a 31 March balance date may also have a provisional tax instalment due this month.

Tips for transfer success

Here are a few tips to help ensure that your tax transfers are processed smoothly:

  • File prior income tax returns - Ensure that all income tax returns for previous years have been filed before submitting your transfer request.
  • Check your IRD balance - Confirm the amount of tax outstanding at IRD. After your tax return has been filed, you can only transfer amounts that are less than or equal to the remaining tax liability.
  • Confirm the effective date of your tax (and swap it forward if needed) – The earliest effective date allowed for 2025 tax (when using purchased or financed tax) is the first day of that tax year - for 31 March 2025 balance dates, that’s 1 April 2024.
    • If you’d like to use tax dated earlier than this, you can swap the tax forward before transferring to earn some interest. Our team is happy to assist you with this.
  • Make use of surplus funds - If you have excess funds in the pool that aren’t required for your 2025 income tax, you can swap these forward to the 2026 year and earn some interest.

Tax pooling and imputation credits

We are often asked about purchasing tax to bring an imputation credit account (ICA) balance back into a nil or credit position, but taxpayers may forget that selling tax pooling funds can also influence your ICA balance.

When you use tax from the pool to meet an income tax liability, your ICA will be credited as if the payment had been made on the effective date of the transferred tax.

Before selling any excess deposits from the tax pool, it is important to check that doing so won’t push your ICA into a debit position, as this can result in imputation penalties and interest. Using pooling effectively can help you manage the timing of ICA movements and optimise your cash flow — but it’s worth reviewing your ICA position before completing any transfers.

Our team can help you assess the impact of pooling transactions on your ICA and ensure you remain in the best position at balance date.

Tax Pooling Associate, Tax, PwC New Zealand

Carla joined Tax Pooling Solutions in early July 2025. Bringing with her a wealth of experience in accounts, administration, and operational management, along with a great sense of humour, we are thrilled to Carla as a part of the team.

We've asked Carla a few questions so you can get to know her a bit better beyond tax pooling!

Can you tell us a little bit about your role in the tax pooling team?

In my current role within the Tax Pooling team, I am primarily responsible for managing the pool’s banking operations and the processes associated with them. My day typically begins with downloading and reviewing bank transactions to ensure payments are correctly detailed, accurately matched to client obligations, and allocated to the correct accounts.

My workload varies depending on the Tax Pooling cycle, which generally revolves around three key process dates each month. During these periods, I handle a mix of tasks, including:

  • Sending reminders for upcoming client payments;
  • Managing administrative tasks to support the team’s workflow;
  • Responding to client queries and providing assistance with their tax pooling needs.
What’s one thing you think people would be surprised to learn about tax pooling?

Many people would be surprised to learn that anyone can use tax pooling. It’s not just limited to companies, it’s available to everyone that pays their own tax. Sometimes life happens and managing tax obligations can get away from you. Tax pooling is a flexible tool that can help anyone get back on track with their payments.

What do you get up to outside of work?

I love Latin dancing — salsa, bachata, and kizomba — and enjoy going out dancing socially (though probably not as often as I’d like!). I’m not much of a gym person, so instead I go to dance fit classes like dancehall, afro, and hip-hop, which I find way more fun. Outside of that, it’s the usual mix of spending time with family and friends, heading to quiz nights, planning my next holiday and sharing plenty of laughs along the way.

If you could travel anywhere tomorrow, where would you go?

I’ve always dreamed of staying in an ice hotel — it’s been on my bucket list for years! The idea of actually sleeping in one does scare me a little (and a holiday in the cold doesn’t sound quite as tempting as cocktails on a beach), but I think one day I’ll just have to bite the bullet. Experiencing the northern lights, being pulled on a sled through the snow, and warming up with hot buttered rum would definitely make up for it.
