About Tax Pooling

Tax pooling is an IRD approved service that helps businesses make the right tax payments at the right time.

So instead of paying IRD directly, taxpayers pay into the tax pool when it suits them and TMNZ makes payments to IRD on their behalf. It’s like a balancing act; since some businesses like to overpay tax during earlier dates, this helps to cover those businesses that need more flexible tax payment arrangements. And that’s the tax pool.
