What happens if your tax return is late or overdue?

In this guide, we examine what constitutes an overdue tax return, detail the penalties you might face, discuss the legal consequences of overdue or late tax returns and explain how to get up to date.

If your tax return is late or overdue, the penalty can be substantial and there may sometimes be legal consequences. It’s an expensive, stressful and surprisingly easy mistake to make. That’s why having a good handle on what happens if your tax return is late or overdue is important.

What is an overdue tax return? 

An overdue tax return hasn’t been filed in time to meet the due date specified by Inland Revenue (IRD). 

What is the penalty for not filing or paying your taxes on time?

The penalty for not filing or paying your taxes on time depends on the type of return due and your overdue return. By law, you must file tax returns by their due dates unless you have applied for an extension of time (EOT) with the IRD. To find out when each return needs to be filed, you can search the IR database of key dates.

Which types of unpaid or overdue taxes are eligible for penalties? 

Several types of unpaid or overdue taxes are subject to penalties in New Zealand. These include:

Income tax returns (IR 3 and IR 4)

Income tax returns that are unpaid or overdue are eligible for penalties based on your net income.

Employment information (IR 348)

If you don’t file your employment information online when you should, the IRD may charge a non-electronic filing penalty. 

GST returns (GST 101 and GST 103)

GST returns are subject to late filing penalties. When your GST return is due depends on whether you use accrual or cash accounting. 

Residential land withholding tax

Residential land withholding tax is deducted from some property sales and paid to the IRD. Failure to pay this tax or not paying it on time results in penalties.

Penalties associated with overdue tax returns 

The IRD charges penalties associated with overdue tax returns starting from the day after your payment was due. This is broken down into three stages:

  • A 1% penalty will be charged the day after the payment due date.

  • 4% penalty for remaining tax (including penalties) on the seventh day after the payment due date

  • 1% penalty every month the remaining tax (including penalties) is unpaid.

If your tax is being reassessed, the IRD will set a new due date and in some cases, the IRD may waive these penalties.

There can be legal consequences for overdue or late tax returns, as failing to lodge them is a criminal offence. In severe cases of non-compliance or tax evasion — including not keeping the correct records for your business, providing false or misleading information‌ or manipulating sales data — you could be prosecuted by the IRD and fined or imprisoned.

How do I get up to date on tax returns? 

You can get up to date on outstanding tax returns by contacting the IRD and having your IRD number handy or logging into your MyIR account. You can see what tax returns are overdue and work through the requirements from there. Alternatively, contact a registered tax agent who can help you navigate the entire process and liaise with the IRD on your behalf.

Overdue tax return FAQs

Am I liable for an overdue tax penalty if I have engaged a tax agent? 

Even if you have engaged a tax agent, the ultimate responsibility is yours. However, tax agents can qualify for extensions on deadlines. If they’ve told the IRD about any issues that have caused a delay, your penalties can be waived.

Can I lodge a tax return from 10 years ago? 

You can lodge a tax return from 10 years ago. However, penalties and interest are likely to apply for late lodgement.

Do I need to lodge a tax return if I didn’t earn over the past 12 months?

You don’t generally need to lodge a tax return if you didn’t earn an income or have other tax obligations. However, if you’re a provisional taxpayer, you may still need to file a return. It’s best to double-check with the IRD.
