Getting the tax foundations right in your first weeks saves a year of clean-up later. This free setup guide walks a new New Zealand business through structure, IRD registrations, GST, provisional tax, and software, in the right order.
What's in the guide
The guide is a practical setup walkthrough for new New Zealand businesses. It is sequenced the way the decisions actually arrive, so you are not bouncing between half-finished tasks.
It covers the five things that matter most at the start:
- Structure: sole trader, company, or look-through company, and the tax and liability differences between them.
- IRD registrations: your IRD number, the right tax type, and employer registration if you will pay wages.
- GST: whether you need to register now (the $60,000 threshold) or whether voluntary registration helps you.
- Provisional tax: what it is, why it tends to surprise people in year two, and how to plan for it.
- Software and records: setting up clean record-keeping from day one so year-end is simple.
It is written in plain English and assumes no prior tax knowledge.
Who it's for
This is for people at the very start of their business journey:
- First-time founders who want to do the admin once and do it right.
- Contractors and freelancers going out on their own and unsure what IRD expects.
- Side-businesses turning serious that have outgrown casual record-keeping.
- New migrants starting a business here who find the IRD system unfamiliar.
If you are weighing whether to be a sole trader or a company, that single choice shapes your tax, your liability, and your paperwork, so it is worth getting clear before you register anything.
The setup steps
The guide follows a logical order. In outline:
| Step | What you decide or do |
|---|---|
| 1. Choose a structure | Sole trader (simple, you are personally liable) or company (separate legal entity, taxed at 28%, more compliance). |
| 2. Register with IRD | Get set up for income tax, and for the right tax type for your structure. |
| 3. Decide on GST | Required over $60,000 turnover; optional below, depending on who your customers are. |
| 4. Plan for provisional tax | Once your tax bill passes the threshold, IRD asks you to pay in instalments. Set money aside early. |
| 5. Set up records and software | Choose a system, separate business and personal banking, and keep everything from day one. |
The biggest first-year trap is cashflow: income tax and provisional tax can land together in year two, so a simple habit of setting aside a portion of every payment makes a huge difference.
One extra habit makes the whole first year easier: separate your business and personal money from day one. A dedicated business bank account turns a tangle of mixed transactions into clean records, makes your GST and year-end far simpler, and keeps the line between you and the business clear, which matters most if you are a company. It costs nothing and saves hours later.
