Starting a business in New Zealand is administratively simple compared with most countries, which is genuinely an advantage and also means people skip steps without noticing.
What you must do
Get an IRD number for the entity. A sole trader uses their personal IRD number. A company, partnership or trust needs its own, applied for once the entity exists.
Incorporate, if you are using a company. Done through the Companies Office, usually within a day. You will need a company name, registered office, address for service, director details and shareholder details. At least one director must live in New Zealand, or in Australia and be a director of an Australian company.
Register for GST if required. Compulsory once turnover exceeds $60,000 in the past twelve months, or where you reasonably expect it to exceed that in the next twelve. The forward-looking limb catches people who sign a contract that will clearly take them over.
Register as an employer before your first payday if you will have staff, which brings PAYE, KiwiSaver and payday filing obligations.
What you probably do not need on day one
Trade mark registration, a shareholders’ agreement drafted by a specialist, an accounting package with every module, and a trust structure are all things that get sold to new business owners and are frequently premature.
The exceptions worth doing early: securing your business name as a domain and on the relevant platforms, and checking that your intended name does not conflict with an existing registered trade mark. Discovering a conflict after you have printed signage is expensive.
Deciding on GST registration below the threshold
Voluntary registration below $60,000 is worth considering where your customers are GST-registered businesses, because they can claim the GST you charge and you can claim on your inputs.
It works against you where you sell to consumers, since your prices effectively rise by 15 percent or your margin falls by the same. The administrative cost is real but modest with decent software.
The first-year deadlines that catch people
- Provisional tax in year two. The first profitable year produces a tax bill and the start of instalments toward the next year. That double hit is the most common cashflow shock in New Zealand small business, and it is entirely predictable.
- GST return dates, which start from your registration date rather than your balance date.
- The company annual return, due each year in the month the company was incorporated. It is not a financial return and it is not optional; companies get struck off for missing it.
- ACC invoices, which arrive after your first return is filed and are usually larger than expected because they cover a period already elapsed.
Set up the money properly from the start
Three habits prevent most first-year problems:
- Separate bank account for the business, always, including for sole traders. Mixing personal and business transactions makes accounts expensive to prepare and obscures whether the business is actually working.
- A second account for tax. Move GST and PAYE out as they are earned. The money was never yours.
- Accounting software from day one. Cheaper than reconstructing a year of transactions from bank statements, and it files GST directly.
Choosing the structure
Sole trader is simplest and offers no liability protection. A company separates you from the business but brings ongoing compliance. Partnerships expose each partner to the others’ obligations. Look-through companies combine limited liability with flow-through tax treatment.
The practical test is risk: if a realistic claim against the business would reach your house, you want limited liability. Beyond that, the decision turns on profitability, who else is involved, and whether you intend to sell.
Other registrations depending on what you do
Food premises registration, alcohol licensing, building practitioner licensing, transport service licences, financial service provider registration and various occupational registrations all sit outside the tax system and are easy to overlook. Check what applies to your specific activity before you trade rather than after.
