Do You Need an Accountant as a Sole Trader in NZ?

A sole trader accountant in NZ is optional, not compulsory. Starting out on your own does not require an accountant by law, and plenty of people manage their own books in the early stages. The real question is when paying for one starts to make sense.

Here is the GST threshold that changes your obligations, what you must do either way, and the signs it is time to bring someone in.

When must a sole trader register for GST?

Inland Revenue says you must register for GST if your turnover was over $60,000 in the last 12 months, or is expected to go over $60,000 in the next 12 months, and you must register within 21 days once that applies (Inland Revenue GST registration). Turnover is your sales excluding GST, not your profit, which catches some sole traders by surprise.

Below the threshold you can register voluntarily. That lets you claim back GST on business expenses, but you must then charge and account for GST on what you earn. Inland Revenue suggests registering voluntarily only when you expect turnover to stay above the threshold.

What must a sole trader do with or without an accountant?

Regardless of GST, every sole trader needs an IRD number, must tell Inland Revenue they are trading, and must file an income tax return declaring their business income. Self-employed people also pay ACC levies, so ask Inland Revenue or ACC how yours will be charged and budget for it.

• Get an IRD number if you do not already have one
• Tell Inland Revenue you are self-employed
• Keep records of income and expenses
• File an annual income tax return and pay the tax owing
• Check whether you need to register for GST, and consider an NZBN if useful

When does an accountant start paying for itself?

Many sole traders manage on their own in the first year with simple income and expenses. An accountant tends to earn their fee when things become more complex: claiming a home office or vehicle use proportionally, handling provisional tax after your first full year, dealing with GST, or wanting to know you are claiming everything you are entitled to.

It is also common to use an accountant only for the annual return and tax position, while handling invoicing and expense tracking yourself in accounting software.

Sole trader or company: should you ask an accountant?

A sole trader operates under their own name with no legal separation between personal and business finances. A company is a separate legal entity. Many people start as a sole trader for simplicity and consider incorporating later as the business grows, taking on staff or carrying risk.

This is a good one-off question for an accountant, because the answer depends on your income, risk and plans. Ask for the likely costs and tax effects in writing before you decide.

How to find an accountant who understands sole traders

Look for someone who regularly works with sole traders and small businesses in your industry, not one whose main clients are large companies. Ask what is included in the fee, which software they use, how they communicate during the year, and who handles your return.
