Any business can register for GST voluntarily, even below the NZ$60,000 threshold, as long as you’re carrying on or intend to carry on a taxable activity. Once registered, the same rules apply as mandatory registration — you charge GST on taxable sales and file returns on your assigned cycle.
The decision usually comes down to whether your customers can claim back the GST you charge them. If they’re GST-registered businesses, the GST is essentially neutral to them. If your customers are individual consumers, they can’t claim it back, and the GST becomes a real cost unless you absorb it into your pricing.
