GST Registration NZ: When Does Your Business Need to Register?

What Is GST Registration in New Zealand?

GST registration is the process of registering a taxable activity with Inland Revenue for Goods and Services Tax in New Zealand.

GST is generally charged at 15% on taxable supplies. A GST-registered business collects GST from customers and generally claims eligible GST incurred on business purchases and expenses.

GST registration is separate from simply having an NZBN, company or IRD number. Starting a business does not automatically mean you must register for GST.

The key question is whether your taxable activity meets the registration requirements under New Zealand GST rules.

For the latest registration requirements, Inland Revenue states that an entity carrying out a taxable activity must register when its turnover was at least $60,000 in the previous 12 months, is expected to be at least $60,000 in the next 12 months, or when GST is added to its prices.

What Is the GST Registration Threshold in NZ?

The current GST registration threshold in NZ is $60,000.

You generally need to register if your taxable activity:

• had turnover of at least $60,000 in the previous 12 months; or
• is expected to have turnover of at least $60,000 in the next 12 months; or
• adds GST to the prices charged for taxable supplies.

The threshold is based on the turnover of the taxable activity. It is therefore important to monitor your business revenue rather than waiting until the end of the financial year.

If your turnover is approaching the threshold, reviewing your expected sales and taxable supplies can help you determine whether GST registration is becoming necessary.

Important: the GST registration threshold is not the same as your business profit. A business can have relatively low profit but still need to register because GST registration is based on turnover and taxable activity.

When Do You Need to Register for GST in NZ?

You should consider your GST position as soon as your business approaches the registration threshold or you begin charging GST.

1. Your turnover has reached $60,000

If your taxable activity has reached the $60,000 threshold over the relevant 12-month period, GST registration may be compulsory.

2. You expect turnover to reach $60,000

You do not necessarily have to wait until your sales actually reach $60,000. If you reasonably expect your taxable activity to reach the threshold in the next 12 months, registration may be required.

3. You add GST to your prices

If you carry out a taxable activity and add GST to the prices you charge, Inland Revenue states that you must register for GST.

4. Your business is growing quickly

A business can move from below the threshold to above it relatively quickly. Monitoring monthly and rolling 12-month turnover can help you identify when your GST obligations may change.

Can You Register for GST Below $60,000?

Yes. Voluntary GST registration is available for businesses whose taxable activity turnover is below $60,000.

There can be legitimate reasons for voluntarily registering. For example, a business may have significant GST-bearing expenses and want to claim eligible GST, or it may prefer to operate within the GST system as it grows.

However, voluntary registration also creates ongoing responsibilities.

Once registered, you generally need to:

• charge GST on taxable supplies;
• file GST returns;
• pay GST owed to Inland Revenue;
• keep appropriate GST records; and
• meet applicable GST compliance requirements.

Inland Revenue notes that voluntary registration can have both advantages and disadvantages, including the ability to claim eligible GST on expenses but the requirement to add GST to prices and file returns regularly.

Should a Small Business Register for GST?

There is no single answer for every small business. If your taxable activity is below $60,000, GST registration is generally optional unless another registration requirement applies.

Before voluntarily registering, consider:

• your current turnover;
• expected business growth;
• the type of customers you sell to;
• your business expenses;
• how much GST you may be able to claim on eligible expenses;
• your pricing structure;
• your administrative capacity; and
• your expected future turnover.

For example, a business selling mainly to GST-registered businesses may approach pricing differently from a consumer-facing business where customers are not able to claim GST.

A GST decision should therefore be considered alongside your wider pricing, cash-flow and business structure.

Do Sole Traders Need GST Registration in NZ?

A sole trader does not automatically need GST registration simply because they are self-employed.

However, if the sole trader carries out a taxable activity and meets the GST registration requirements, registration is required.

Inland Revenue confirms that self-employed people generally need to register for GST when their business activity meets the $60,000 threshold.

Sole traders should monitor their business turnover and consider their GST position as the business grows.

Do Contractors Need GST Registration in NZ?

Contractors may need GST registration if their taxable activity meets the applicable registration requirements.

Being called a contractor rather than an employee does not automatically determine whether GST registration is required.

If you work as an independent contractor, it is important to understand whether your activity is taxable for GST purposes and whether your turnover has reached or is expected to reach the registration threshold.

This can be particularly important for consultants, tradespeople, freelancers, professional service providers and other self-employed contractors.

How to Register for GST in NZ

If you need to register, Inland Revenue allows businesses to complete GST registration through myIR.

Step 1: Check whether you need to register

Review your taxable activity and calculate your turnover for the previous 12 months and expected turnover for the next 12 months.

Step 2: Gather your business information

You will generally need information including your IRD number, business turnover information and business industry classification details.

Step 3: Choose your GST filing frequency

When registering, you need to select an appropriate GST filing frequency.

Step 4: Choose your accounting basis

You also need to select an accounting basis for calculating GST. Your circumstances determine which options are available to you.

Step 5: Complete the registration through myIR

In myIR, select the GST registration option under registration, application and enrolment and follow the prompts.

Inland Revenue currently states that GST registration requests are generally processed within 10 working days, although additional information may be requested.

What Information Do You Need to Register for GST?

Before completing your GST registration NZ application, prepare the relevant business information.

• IRD number of the person or organisation;
• turnover for the previous 12 months;
• expected turnover for the next 12 months;
• business industry classification code;
• preferred GST filing frequency; and
• GST accounting basis.

Having this information ready can make the registration process easier and help you make more informed decisions about your GST setup.

What Happens After GST Registration?

GST registration creates ongoing tax and record-keeping responsibilities.

Once registered, your business generally needs to:

• charge GST on taxable supplies;
• calculate GST collected and eligible GST paid;
• file GST returns;
• pay any GST owing by the relevant due date;
• keep GST and supporting business records; and
• correct errors where necessary.

Your GST return effectively compares GST collected on taxable sales with eligible GST incurred on business purchases and expenses.

If the GST collected is greater than the GST you can claim, you generally pay the difference to Inland Revenue. If eligible GST paid exceeds GST collected, a refund may be available.

How Does GST Registration Affect Your Prices?

GST registration can affect how you price your products and services.

For a GST-registered business, GST is generally added to taxable prices unless a different GST treatment applies.

For example, if a GST-exclusive service is priced at $1,000 and the standard 15% GST rate applies:

$1,000 + $150 GST = $1,150 GST-inclusive price.

If your customers are consumers who cannot claim GST, the GST-inclusive price may be particularly important when comparing your pricing with competitors.

Businesses should therefore consider GST when developing pricing strategies rather than treating it as an afterthought.

Can You Claim GST on Business Expenses?

A GST-registered business may generally claim eligible GST incurred on purchases and expenses that relate to its taxable activity, subject to the applicable rules.

This can include GST on qualifying business purchases where the required conditions and records are met.

You should keep appropriate tax invoices and other supporting records and make sure expenses are treated correctly before claiming GST.

Not every payment automatically results in a GST claim, so businesses should check the GST treatment of unusual or significant expenses.

How Often Do You File GST After Registration?

Your GST filing frequency depends on your circumstances and the option selected when registering.

Businesses can have different GST filing frequencies, including monthly, two-monthly and six-monthly options, subject to Inland Revenue requirements and eligibility.

Your GST filing frequency affects how often you need to calculate GST, prepare a return and make any required payment.

For a business with regular transactions, choosing an appropriate filing frequency can also affect cash-flow planning and administrative workload.

7 Common GST Registration Mistakes in NZ

1. Waiting until turnover is far above $60,000

Businesses should monitor turnover regularly rather than discovering their registration obligation after the threshold has already been exceeded.

2. Confusing turnover with profit

GST registration is based on taxable activity and turnover rather than simply business profit.

3. Assuming every new business must register

Starting a business does not automatically mean GST registration is required. The registration criteria need to be considered.

4. Registering without considering pricing

Voluntary registration can affect customer pricing and cash flow, so it should be considered as part of your overall business plan.

5. Forgetting that GST creates ongoing filing obligations

GST registration is not a one-time application. Registered businesses need to continue meeting their filing, payment and record-keeping obligations.

6. Not keeping supporting records

GST claims and business transactions should be supported by appropriate records.

7. Getting registration timing wrong

If you become liable for GST registration, timing matters. Businesses should act promptly and obtain professional advice if they are unsure when their registration obligation begins.

What Happens If You Register for GST Late?

If you were required to register but did not register on time, there can be consequences for your GST obligations.

Depending on the circumstances, Inland Revenue may determine the appropriate registration date and the GST that should have been accounted for.

If you believe your business should already have been registered, do not simply ignore the issue. Review your turnover, taxable supplies and records and contact Inland Revenue or a qualified tax professional.

In exceptional circumstances, Inland Revenue can consider backdating a GST registration, including situations where a business has been adding GST to prices without being registered.

Is Your GST Number the Same as Your IRD Number?

For GST registration, Inland Revenue states that your GST number will be the same as your IRD number.

This means your GST registration is linked to your existing Inland Revenue tax identity rather than creating a completely separate number.

Can You Cancel GST Registration Later?

Yes, GST registration can be cancelled in certain circumstances.

For example, if your taxable activity stops, you may need to cancel your GST registration. If your business continues but turnover falls below the threshold, cancellation may also be possible depending on the circumstances.

Cancelling GST registration does not mean you can simply stop filing immediately. A final GST return may be required.

If you cancel your GST registration, you generally stop charging GST on taxable sales and can no longer claim GST on eligible expenses as a GST-registered person.

See Inland Revenue’s current GST cancellation guidance.
