No Income This Month? Do You Still Need to File a GST Return in New Zealand?

Many new business owners in New Zealand face a similar situation. Their company is already registered for Goods and Services Tax (GST), but business has been slow during a particular filing period, or they have not generated any income at all. It is easy to assume that if there is no GST to pay, there is no need to file a GST return.

However, this is not necessarily the case. If your business remains GST-registered, you must generally file a GST return for every taxable period, even when there is no GST payable. If there are no reportable transactions or adjustments during the period, you may need to file what is known as a Nil GST Return.

The important distinction is that having no GST to pay does not mean you have no GST filing obligations.

What Is a Nil GST Return?

A Nil GST Return is a GST return filed when a business has no GST transactions or adjustments to report during a particular filing period, resulting in a zero return. This can happen when a newly registered company is still preparing to start trading, or when an existing business temporarily has no sales or purchases.

For example, a company may have completed its GST registration but has not yet started operating. If it has no taxable sales, purchases or other GST adjustments during the filing period, it may need to submit a Nil GST Return.

However, having no sales does not automatically mean your GST return will be nil. If your business has incurred GST-inclusive expenses during the period, you may still be entitled to claim input GST, provided the relevant requirements are met. In some cases, this could result in a GST refund.

For new business owners, understanding this difference is important. No income, no GST payable and a Nil GST Return are not necessarily the same thing.

When Is Your GST Return Due?

In New Zealand, GST-registered businesses generally file their returns monthly, two-monthly or six-monthly, depending on their registered filing frequency. When registering for GST, businesses select an appropriate filing frequency and must continue submitting returns according to that schedule.

Generally, GST returns and any associated payments are due on the 28th day of the month following the end of the taxable period. For example, a GST period ending on 31 May will usually have a filing and payment deadline of 28 June.

There are two important exceptions. GST returns for periods ending on 31 March are generally due on 7 May, while returns for periods ending on 30 November are generally due on 15 January. Due dates may also be affected by weekends and public holidays.

Rather than relying on memory, business owners should regularly check their myIR account to confirm their filing frequency, outstanding GST returns and upcoming deadlines.

Why You Should Not Skip a GST Return When There Is No Income

If your company remains registered for GST, simply ignoring a filing period because there were no business transactions can create compliance issues. Inland Revenue (IRD) may record the return as overdue, even if the amount of GST payable would have been zero.

Repeatedly missing GST returns can lead to additional administrative work, IRD follow-ups and potentially late filing penalties. It can also make it more difficult to keep your business tax records organised.

A better approach is to review your GST position at the end of every filing period. Even if your business has not generated any income, you should check whether there were any expenses, purchases or adjustments to report and submit the appropriate GST return by the deadline.

Developing this habit early can prevent multiple outstanding returns from accumulating in your myIR account.

Should You Cancel GST Registration If Your Business Has No Income?

A temporary period without income does not necessarily mean you should cancel your GST registration. For example, your company may still be preparing to launch, waiting for new projects or experiencing a seasonal slowdown. These circumstances do not automatically mean the business has stopped carrying out a taxable activity.

However, if your company has been inactive for an extended period and you no longer intend to carry on a taxable activity, you should review whether your GST registration remains appropriate. Depending on your circumstances, cancelling your GST registration may be required.

It is also important to understand that cancelling GST registration involves more than simply submitting a cancellation request. Your business will generally need to file a final GST return and may need to account for business assets it retains, outstanding customer payments, unpaid supplier invoices and other relevant adjustments.

Before cancelling your GST registration, it is worth reviewing your business activities and financial records to understand the potential tax implications.

What Should New Business Owners Know About GST Filing?

For businesses that have recently registered for GST, understanding a few basic requirements can make GST compliance much easier. You should know which GST accounting basis your company uses, how frequently you need to file, when your next return is due and what records need to be maintained.

You should also understand that GST filing obligations can continue even when your company has no income or transactions during a particular period.

For many new businesses, the main difficulty is not calculating the 15% GST rate. It is understanding when to file, what needs to be included in each return and how to maintain accurate supporting records.

Establishing a reliable bookkeeping and GST filing process from the beginning can reduce the risk of errors and help you manage your tax obligations as your business grows.
