Many different business structures are available to you if you want to start your own business. You can choose to operate business as a sole trader, partnership, or company. These three different structures all have very different legal and financial obligations. It is essential to understand the distinction between them to ensure that you are paying tax correctly. This article will outline how each business structure works and how different structures are taxed in New Zealand. Additionally, we will outline goods and services tax (GST) and when it may be appropriate for your business to pay it. 

Sole Trader

Sole traders are people who start their own businesses as an individual person. They do not register their business as a company. Often, these people are tradespeople or those who have skills to market and profit from. It is quick and easy to become a sole trader, and you do not have to undertake a formal registration process. Likewise, you have total control over the business and its profits. However, you are also responsible for paying off the debts you accrue as a sole trader, which can put your personal assets at risk. 

As a sole trader, you pay income tax as an individual. You do not need to set up a separate tax account for your sole trader business, as you technically are the business for legal purposes. You are also responsible for the business ACC levies

Most sole traders pay tax in one go at the end of the financial year. To do this, you need to ensure that you keep thorough and meticulous records of the amount you are withdrawing from your business. 

No matter the business structure, you need to ensure that you keep detailed records of your business’:

  • income;
  • expenses; and 
  • profits. 

It is vital to ensure that you are paying the correct amount of tax, particularly if anyone disputes your tax amounts. If there is an issue with your business taxes, you may face serious legal consequences.


A partnership is when two or more people form a business. A partnership agreement will typically govern a partnership, setting out how each partner will share the business’:

  • profits; 
  • expenses; and 
  • responsibilities. 

This business structure can be beneficial as it allows you to share the business’ challenges with a like-minded partner. Typically, this business structure suits architects, lawyers, and accountants. 

A partnership, unlike a company, is not a separate legal entity. Therefore, a partnership does not pay tax collectively. The income is distributed between all partners, who pay income tax on their payments from the business. Typically, each partner will file a tax return annually stating their profit from the partnership, which they will then be taxed on. Additionally, the partnership itself will need to submit a tax return outlining the business’s expenses and profits. Therefore, you will need to register for a partnership tax number


Companies work slightly differently. Companies are separate legal entities from the people who own and operate them. Therefore, there is an extensive process of registration to register a company. Likewise, there is continual annual upkeep that you must do to maintain your company status. 

Additionally, the distinction between companies and shareholders links to the accountability of owners in the case of debts. For a company, because it is a separate legal entity, the directors and shareholders are not personally liable for the company’s debts. So, company directors and shareholders enjoy the protection of limited liability.

This is different for a sole trader who is considered as one and the same as their business, putting their personal assets at risk if anything goes wrong.  

Further, a company will have both income and expenses. A company will be taxed on its profits – its income minus expenses. Also, the company’s directors will receive a salary from the company’s earnings over the year. This amount will be taxed according to each director’s personal tax rate. Additionally, if a company distributes profit to shareholders, the shareholders will then pay income tax on these amounts.  


No matter what type of business structure you have, if you earn over $60,000 in 12 months, you will need to register for a goods and services tax (GST). This will add 15% to the price of your products and services, which goes to the government. However, it will also mean that you can claim back the GST you pay when buying goods and services for your own business. 

Performance Improvement Plan

When your employee does not perform at the expected level, a performance improvement plan (PIP) may be required to get them back on track. Our free PIP template will assist.
