If the IRD selects you for a tax audit – or if you make a voluntary disclosure – you will receive a notice of tax reassessment. An income tax reassessment will determine the amount of additional tax you may owe. In these situations, you can use TMNZ to help you pay your reassessed tax. Using an IRD approved intermediary like TMNZ can reduce your interest costs by up to 30%. You may also get more time to pay. New Zealand’s tax pooling rules allow for reassessments of different types of taxes, such as PAYE, FBT, GST, NRWT, terminal tax and provisional tax.
