Sole Trader Or Company For Consultants In NZ?

byAlex Solo11 min read

You have landed a bigger consulting opportunity, the client has sent through a serious-looking contract, and suddenly your business structure matters a lot more than it did when you were invoicing smaller jobs.

For many consultants, the choice between staying a sole trader and registering a company in New Zealand isn't just about tax or admin. It affects how liability caps work, who owns your work product, whether procurement will approve you, and what happens if the contract includes a restraint or personal guarantee.

This doesn't have to be complicated. The key is to match your structure to the risks and opportunities in the contracts you're about to sign.

Should I Stay A Sole Trader Or Register A Company In NZ?

It depends on the size of your contracts, the risk in your work, and how your clients expect to engage you.

As a sole trader, you and your business are legally the same person. You can trade under your own name or a business name, invoice clients, register for GST if needed, and keep things fairly simple. For early-stage consulting work, that can be enough.

A company is a separate legal entity registered with the Companies Office under the Companies Act 1993. It can sign contracts, own assets, receive payment, employ people and take on obligations in its own name.

For consultants, the company structure often becomes attractive when:

  • You're signing higher-value client contracts.
  • Your clients ask for a company number, NZBN or proof of incorporation.
  • Your contract has liability caps, indemnities or personal guarantee wording.
  • You create valuable IP, templates, software, training materials or processes.
  • You plan to hire staff, subcontract work or bring in another owner.
  • You want your consulting brand to sit separately from you personally.

A company isn't automatically better. It comes with director duties, annual filings, company records and usually more accounting admin. You should also get tax advice before changing structure, because tax treatment, drawings, salary, GST and ACC can all affect the real-world outcome.

Still, if you're about to sign a larger contract, it's worth reviewing the structure before you sign. Once you sign personally, you may not be able to simply swap in a company later without the client's consent.

How Does A Company Change Your Liability In Consultant Contracts?

A company can help limit your personal exposure, but only if the contract is set up properly and you don't give that protection away.

If you operate as a sole trader, you personally sign the contract. If something goes wrong and the client has a claim, your personal assets may be exposed, subject to the contract wording and any insurance cover.

If your company signs the contract, the starting point is different. The company is the contracting party, so the client usually claims against the company rather than you personally. This is one reason many consultants incorporate before taking on bigger work.

However, limited liability has limits. You may still be personally exposed if:

  • You sign a personal guarantee.
  • You sign the contract in your own name instead of the company's name.
  • You personally commit negligence or misleading conduct.
  • You breach director duties under the Companies Act 1993.
  • You trade while the company can't meet its obligations.
  • The contract makes you personally responsible for confidentiality, IP or restraint obligations.

A Simple Example

Priya is an independent data consultant. She is offered a 12-month project at $8,000 per month, so the total fees are $96,000. The client's contract says Priya's liability is capped at fees paid in the previous 12 months.

If Priya signs as a sole trader, that $96,000 cap applies to her personally. If her company signs, the cap is more likely to apply to the company, provided there's no personal guarantee and the signature block is correct.

That difference matters. If Priya also negotiates exclusions carefully, aligns the cap with her insurance, and avoids signing personally, she has a much clearer risk position before the work begins.

Watch the indemnity clauses too. A liability cap may not apply to every claim. Some contracts exclude privacy breaches, IP infringement, confidentiality breaches or wilful misconduct from the cap. Those carve-outs can be sensible, but they need to match the real risk in your consulting work.

Will Incorporating Help With IP Ownership And Restraint Clauses?

Yes, incorporating can make IP ownership and brand ownership cleaner, but the contract wording still does most of the heavy lifting.

Consultants often create valuable IP without realising it. This might include:

  • Strategy frameworks and reports.
  • Training materials and slide decks.
  • Software code, automations or dashboards.
  • Marketing copy, designs, brand assets or campaign plans.
  • Templates, methods, processes and know-how.

If you're a sole trader, that IP usually sits with you personally unless you have assigned it elsewhere. If you operate through a company, you may want the company to own the business IP, the brand name and client-facing materials. That can make it easier to license your materials, bring in subcontractors, or eventually build a business that isn't completely tied to you personally.

Your consultant agreement should clearly separate:

  • Pre-existing IP: tools, templates, code, frameworks and materials you already had before the project.
  • Client deliverables: the specific work product the client pays for.
  • Working files and know-how: drafts, methods and general expertise you use across clients.
  • Licence rights: what the client can use, copy, edit, share or resell.

Don't assume that using a company means you keep ownership of everything. Many client contracts say all IP created in connection with the services is assigned to the client. That may be fine for the final report, but risky if it accidentally transfers your reusable templates or software.

Restraint clauses need the same careful read. A client may try to stop you from working with competitors, approaching its staff, or providing similar services for a period after the contract ends. In New Zealand, restraints are more likely to be enforceable where they're reasonable and protect a legitimate business interest. A wide restraint that stops you doing ordinary consulting work can be a serious issue, especially if one client isn't paying you like an employee or exclusive contractor.

If you trade under a distinctive brand, you can also consider registering a trade mark through IPONZ. A company structure can then help keep the brand, contracts and IP ownership aligned.

Do Larger Clients Prefer A Limited Company?

Often, yes. A company isn't legally required for consulting, but larger clients may prefer or require it for procurement and risk reasons.

When you deal with bigger organisations, government-related entities or corporates, their onboarding process may ask for details such as:

  • Your company name and company number.
  • Your NZBN.
  • GST registration status.
  • Insurance certificates, such as professional indemnity and public liability.
  • Health and safety, privacy or information security documents.
  • Bank account details in the business name.
  • Details of directors or beneficial owners.

None of this means a sole trader can't win serious consulting work. Many do. But if the client has a procurement checklist built around companies, staying as a sole trader can slow things down or trigger extra questions.

GST is another practical point. In New Zealand, you generally need to register for GST if your taxable supplies are more than $60,000 in a 12-month period, or are expected to exceed that amount. This rule can apply whether you're a sole trader or a company. Registering a company doesn't automatically register you for GST, so don't treat those steps as the same thing.

Privacy can also become more relevant as you move upmarket. If you handle personal information for clients, the Privacy Act 2020 may affect how you collect, use, store and disclose that information. Larger clients may want to see privacy and data security obligations in your contract, particularly if you access customer databases, HR records, health information or analytics platforms.

The practical point is simple. A company structure can help you look procurement-ready, but it works best when your contracts, insurance and compliance documents tell the same story.

How Do I Register A Company In New Zealand?

You can register a company in New Zealand through the Companies Office, and you should do it before signing contracts you want the company to hold.

The process is usually straightforward, but it's worth slowing down on the details. A small typo in the company name, shareholding or signature block can create confusion later.

Company Registration Steps

  1. Choose And Reserve A Company Name: Check that the name is available and not too close to another business name or trade mark.
  2. Decide On The Shareholders: Work out who owns the company and how many shares each person or entity will hold.
  3. Appoint Directors: Your company needs at least one director who lives in New Zealand, or one director who lives in Australia and is also a director of an Australian company.
  4. Confirm Addresses: You'll need registered office, address for service, director and shareholder details.
  5. Consider A Constitution: A company constitution is optional, but it can customise some company rules beyond the Companies Act 1993.
  6. Register With The Companies Office: The Companies Office publishes current fees. Common fees include $11.50 including GST to reserve a company name and $136.55 including GST to incorporate a company.
  7. Set Up Tax And Business Records: Arrange IRD details, GST if required, payroll if you'll employ staff, accounting records and a business bank account.
  8. Update Your Contracts: Make sure new client contracts are issued to and signed by the company, not you personally.

Once registered, your company has ongoing obligations. You need to file an annual return with the Companies Office, currently with a filing fee of $57.20 including GST, and keep company details up to date. Directors also need to follow their duties under the Companies Act 1993, including acting in good faith and not allowing the company to trade recklessly.

If there's more than one owner, don't rely on the Companies Office record alone. A shareholders agreement can cover decision-making, dividends, exits, deadlocks, restraints, confidentiality and what happens if someone stops contributing.

Can A Company Stop A Consultant Being Treated Like An Employee?

No, a company doesn't automatically stop employment law questions from arising, especially if the working relationship looks like employment in practice.

This point matters when you have one major client and work with them for a long time. Calling yourself a consultant, invoicing through a company, or signing an independent contractor agreement or employment contract is helpful, but it isn't the whole answer.

New Zealand employment law looks at the real nature of the relationship, not just the label in the contract. The Employment Relations Act 2000 focuses on substance over labels, so the way the arrangement works day to day is important.

For consultants, risk increases where the client:

  • Controls your hours, location and daily tasks like a manager would.
  • Stops you from working for other clients without a strong commercial reason.
  • Requires you to use only its tools, email address and systems.
  • Integrates you into internal teams in the same way as employees.
  • Pays you like wages rather than for deliverables or services.
  • Requires ongoing personal service with no genuine ability to delegate or use help.

If you run a genuine consulting business, your paperwork should support that. Your agreement should describe the services, deliverables, fees, independence, ability to work for others, use of subcontractors if appropriate, insurance, tax responsibility and your control over how the work is performed.

This isn't just about avoiding employment issues. Clear contractor terms help you preserve your margins, protect your IP and show larger clients that you're running a real business, not just filling a seat inside theirs.

What Should My Consultant Agreement Include Before You Sign?

Your consultant agreement should match your structure, your risk and the type of work you actually deliver.

A free template can be a useful starting point, but templates often miss the details that matter most for consultants: liability caps, reusable IP, restraint wording, privacy obligations and who signs the contract. Before you use any agreement with a larger client, a lawyer should tailor it to your business and the client relationship.

Consultant Agreement Outline

  1. Parties: State whether the contracting party is you personally or your company, using the correct legal name and NZBN if relevant.
  2. Services And Deliverables: Describe what you'll provide, what is out of scope and any assumptions the quote depends on.
  3. Fees And Payment: Set your rates, milestones, invoice timing, GST treatment and consequences for late payment.
  4. Term And Termination: Explain when the engagement starts, how it ends and what happens to unpaid work.
  5. Client Responsibilities: List information, access, approvals and cooperation the client must provide.
  6. Intellectual Property: Separate pre-existing materials from client deliverables and state any licence rights clearly.
  7. Confidentiality: Protect both sides' confidential information and set sensible exceptions.
  8. Privacy And Data Security: Cover how personal information will be handled under the Privacy Act 2020.
  9. Liability Cap And Exclusions: Set a fair cap and identify any claims that sit outside it.
  10. Insurance: Record the insurance you hold and make sure it matches the contract obligations.
  11. Restraints And Non-Solicitation: Keep any restrictions narrow, reasonable and relevant to the project.
  12. Independent Contractor Terms: Confirm you're operating independently and are responsible for tax, ACC and your own business costs.

Also check the signature block. If you have incorporated, the agreement should usually be signed by your company, by you as director or authorised signatory. Avoid signing once as the company and again personally unless you understand why the client is asking for that.

Key Takeaways

  • A sole trader structure is simple, but larger consulting contracts can make personal liability, IP ownership and restraints more serious.
  • A company can help separate your personal affairs from your consulting business, but only if contracts are signed correctly and you don't give personal guarantees without understanding them.
  • Client contracts should be checked carefully for liability caps, indemnities, IP assignment, privacy obligations and restraint clauses.
  • You can register a company through the Companies Office, but you also need to update your contracts, tax setup, banking, insurance and business records.
  • Incorporating doesn't automatically fix employment status issues. The real working relationship still matters under New Zealand employment law.
  • A tailored consultant agreement gives you a cleaner base for winning bigger clients and protecting the business you're building.
