Understanding your plan options: Tax Purchase, Tax Finance, Tax Deposit

Tax Pool Options: Overview

TMNZ offers three ways to handle a tax date through the pool. Which one applies mostly comes down to two questions: has the date already passed, and whose money is covering it.

Compare the options

Tax Purchase

  • For a tax date that's: Already passed
  • Whose funds: TMNZ's, already sitting in the pool
  • Cost: Purchase interest only, floating rate, no fee. The quoted rate is held for a set window if paid promptly.
  • Repayment: Full payment, or flexible (pay what you can, until covered).
  • Typical use: Catching up a missed date without wearing IRD's interest and penalties.

Tax Finance

  • For a tax date that's: Still upcoming
  • Whose funds: TMNZ's, released once a fee is paid upfront
  • Cost: A finance fee paid upfront, which locks a fixed rate for the full term.
  • Repayment: Fee first, then core tax as a single repayment, or monthly instalments (currently staff-arranged only).
  • Typical use: Spreading the cost of a date you can see coming, ahead of it arriving.

Tax Deposit

  • For a tax date that's: Still upcoming
  • Whose funds: Your own
  • Cost: None: no fee, no interest either way.
  • Repayment: Not applicable — it's already the client's own funds.
  • Typical use: Parking funds you already have, ready for a date you're covering yourself.
Quick summary
  • If the tax date has already passed: Tax Purchase is the relevant option.
  • If the tax date is still ahead: Tax Finance or Tax Deposit may apply, depending on whose funds are being used.
  • If it's the client's own money: Tax Deposit is the fit.
  • If TMNZ funds are being used before the date: Tax Finance is the fit.
Straddling the Tax Date

A plan can also straddle the tax date itself: amounts paid before the date count as a Deposit, amounts paid after count as a Purchase. That combination isn't a separate product to choose — it's simply what a flexible payment plan becomes if it runs past the date.

Tips & Things to Know
  • If a date has already passed, Tax Purchase is the only one of the three that applies. Tax Finance needs a future date to work from.
  • Tax Deposit costs nothing because it's the client's own money. Purchase and Finance both draw on TMNZ's pooled inventory, so both carry a cost — interest on Purchase, a fee on Finance.
  • Tax Purchase has a hard IRD deadline for how late it can be created against a missed date. Ask your client's tax team for the current cutoff rather than assuming a fixed number of days.
  • Self-service currently supports full or flexible payment on a Tax Purchase, and a single repayment on Tax Finance. A monthly instalment Finance plan needs to be set up directly with TMNZ for now.
  • None of the three plan types block you from holding others — a client can have a Purchase, a Finance, and a Deposit plan open at the same time, for different tax dates.
