What is the difference between zero-rated and exempt for GST?

Zero-rated supplies are taxable supplies charged at 0%, and the supplier can recover input tax on the costs of making them. Exempt supplies are outside the GST charge, and input tax on related costs generally cannot be recovered. The customer pays no GST either way, which is why the two get confused, but the effect on the supplier's recoverable input tax is completely different.

Are exports zero-rated in New Zealand?

Exported goods can generally be zero-rated where the conditions are met, including that the goods are exported within the required period and the supplier holds evidence of the export. The zero-rating is conditional on the documentation, not just on the customer's location. An overseas billing address on its own does not establish that a supply qualifies.

How often is GST filed in New Zealand?

Monthly, two-monthly or six-monthly depending on turnover and the option elected, with two-monthly the common choice for a small or medium business. Higher turnover businesses are required to file more frequently. The cycle determines how quickly a classification error compounds, because each period repeats the same mistake until someone checks.

Can input tax be claimed on exempt supplies?

Generally no. Input tax attributable to making exempt supplies is not recoverable, which is why a business making both taxable and exempt supplies has to apportion. Claiming on a blended basis across both over-recovers on the exempt side and is one of the most common errors in a return that otherwise looks entirely normal.

How are past GST errors corrected in New Zealand?

Smaller errors can generally be corrected in a later return within the limits Inland Revenue sets, while larger errors are disclosed separately. Making a voluntary disclosure before Inland Revenue raises the issue generally produces a better penalty outcome than being assessed. Each period is quantified individually first, because the correction route depends on the size of the error in that period rather than the net across all of them.

Zero-rated versus exempt supplies, and why the difference is money

Zero-rated and exempt supplies are not interchangeable: a zero-rated supply is taxable at 0% and the input tax on related costs is recoverable, while an exempt supply is outside the charge and that input tax generally is not. This is an illustrative example of how Salt approaches a GST classification review, using a New Zealand e-commerce exporter as the profile.

Ask how we'd handle this

Scenario — an illustrative example of how Salt approaches this problem. Not a description of a specific client engagement.

The business shape it describes: New Zealand e-commerce exporter, two-monthly GST.

Scenario covers: Bookkeeping, GST review and correction of filed returns
Jurisdiction: New Zealand
Sector: E-commerce

The setup

Take a New Zealand e-commerce business exporting most of its output, filing GST on a two-monthly cycle, and treating all non-domestic sales as one category.
Returns have been filed on time throughout. The classification underneath them has never been checked.

What usually turns out to be wrong

Zero-rated exports and exempt supplies posted to the same account, which makes the two indistinguishable in the ledger and the return.
Input credits claimed on a blended basis rather than by reference to the actual supply type, so the recovery position is wrong in both directions across different periods.
A product category treated as exempt when it was zero-rated, which understates recoverable input tax and quietly costs money every period.
Export documentation not consistently retained, even though zero-rating an export depends on being able to evidence that the goods left the country within the required time.

How this would be worked

Separate zero-rated and exempt supplies at the transaction level with distinct GST codes, so the classification is recorded once at source.
Review the filed periods and recalculate the input credit position by supply type rather than on a blended basis.
Quantify each period separately, because netting the errors across periods hides which ones need correction in which direction.
Prepare corrections in both directions, including the periods where the correction increases the liability.
Tighten export evidence retention, since the zero-rating depends on the documentation as much as on the transaction.

Why we'd be the right fit

Zero-rated and exempt supplies look interchangeable on an invoice and are not. The difference decides what input tax is recoverable, which is how a return can be filed on time for two years and still be wrong underneath.
Reviewing multiple periods and correcting in both directions means disclosing the errors that go against the client as well as the ones producing a refund.

What the business would be able to do

GST coding would happen at the point of sale rather than being adjusted at return time, so the classification is made once by someone who knows the answer.
Input tax recovery would rest on the actual supply type, which is the only basis that holds up if the return is examined.
Export zero-rating would be supported by retained documentation rather than by the fact that the customer had an overseas address.

What we'd flag

A classification review corrects in both directions, and some periods will produce an additional liability rather than a refund. A review that only surfaces the favourable half is not a review, and it does not resolve the underlying exposure.
