The final payment date for taxpayers with a 7 April terminal tax date to pay their 2018 income tax arrangement via TMNZ is 18 June 2019.

Legislation prevents TMNZ from helping beyond 75 days after a taxpayer’s terminal tax date.

Unpaid Flexitax® or Tax Finance balances will incur IRD interest and late payment penalties. IRD will charge interest and late payment penalties from the date the tax payment(s) were originally due.

2018 income tax: What are my options?

Below are three options for clients if paying their 2018 income tax arrangement with TMNZ by the deadline is going to be a push.

Interface Financial Group

The Interface Financial Group offers an invoice discounting service. It provides money straight away to clients by purchasing your unpaid invoices.

It pays up to 90 percent of the invoice amount. The only cost is a discount fee it earns on the invoice(s) it purchases from a business.

Your customers then pay the full invoice amount to The Interface Financial Group on the due date.

The service can be used at the sole discretion of business owners and is provided on a use-it-as-you-need-it basis.

You create a business loan every time you draw down. The loan is repayable monthly (one to 12 months).
