Business Insurance for Sole Traders: What You Actually Need

·12 min read

Running a one-person business in Australia comes with a long enough to-do list without adding insurance to it. But here’s the reality: if something goes wrong on the job — someone gets hurt, property gets damaged, a client sues you for bad advice — the cost lands on you personally. Not a company. Not a boss. You.

The good news is you almost certainly don’t need every type of business insurance out there. Most sole traders can get properly covered with one or two core policies, and the annual cost is often less than a weekly coffee habit. This guide walks through what’s actually mandatory, what’s worth having, what you can safely skip, and roughly what you’ll pay.

The Difference Between Personal Insurance and Business Insurance

Before diving into specific covers, it’s worth clearing up the most common point of confusion for new sole traders: personal insurance doesn’t cover your business activities.

Your personal car insurance, for example, typically excludes use of the vehicle for work purposes beyond commuting. Your home and contents policy generally won’t cover business equipment kept at home unless you’ve specifically declared it. And your personal income protection through superannuation might have exclusions or waiting periods that make it unsuitable as your primary safety net.

When you’re a sole trader, there’s no legal separation between “you” and “the business.” That means a lawsuit against your business is a lawsuit against you personally — and your personal assets, including your house, car, and savings, are all on the line. Business insurance exists to put a buffer between your work and your personal finances.

What’s Legally Required

Let’s start with what you don’t have a choice about. The mandatory insurance requirements for sole traders depend on your industry and whether you employ anyone.

Workers Compensation Insurance

If you employ anyone — even one casual staff member — you need workers compensation insurance. This is mandatory in every Australian state and territory, though the specific scheme and insurer vary by jurisdiction. In NSW, for example, it’s managed through icare; in Victoria, through WorkSafe; in Queensland, through WorkCover Queensland.

If it’s genuinely just you — no employees, no apprentices, no subcontractors who could be deemed workers — then workers comp is generally not required. But here’s the catch: in some states, certain industries or contract arrangements mean that even sole traders must hold their own workers comp. Check your state regulator’s website before assuming you’re exempt.

Compulsory Third Party (CTP) Insurance

If you drive a vehicle for any work-related purpose — visiting clients, delivering goods, travelling between job sites — your vehicle must have CTP insurance. This comes bundled with your vehicle registration in most states and covers injuries you cause to other people in an accident. It does not cover damage to vehicles or property.

What CTP also doesn’t cover is damage to your own vehicle if you’re at fault. If your vehicle is essential to your business, you may want to consider a commercial motor vehicle policy rather than relying on a standard personal car insurance policy, which may exclude or limit cover for business use.

Professional Indemnity Insurance

Professional indemnity (PI) insurance is legally required for certain professions even if you’re a sole trader. This includes solicitors, accountants, financial advisers, real estate agents, and registered builders in some states. If your profession has a mandatory PI requirement, you won’t be able to obtain or renew your licence or professional registration without it.

If your profession doesn’t mandate it, PI insurance becomes optional — more on that below.

Even when insurance isn’t legally required, there are covers that most sole traders should seriously consider because the risk of going without them simply isn’t worth it.

Public Liability Insurance

Public liability insurance is the closest thing to a universal essential for sole traders. It covers you if your business activities cause injury to someone else or damage to someone else’s property. If you work at client sites, interact with members of the public, or operate in shared spaces, this is the policy that protects you when something goes wrong.

Here’s why public liability is practically non-negotiable for most sole traders: client contracts almost always require it. Whether you’re a freelance photographer shooting a wedding, a carpenter doing a kitchen renovation, or an IT contractor working in a corporate office, the contract you sign will almost certainly include a clause requiring you to hold public liability insurance — typically with a minimum cover of $10 million or $20 million.

Even when there’s no written contract, commercial landlords and venue managers often require proof of public liability before they’ll let you work on their premises. Market stalls, pop-ups, event spaces — all of them will ask for a certificate of currency before they hand over access.

What cover level should you choose? For most sole traders, $10 million is the standard starting point and covers the vast majority of contract requirements. If you work on large commercial projects or government contracts, you may be required to carry $20 million. The premium difference between the two is often surprisingly small — sometimes as little as $80–150 more per year for the higher limit, so if you’re unsure, it’s worth checking the cost of stepping up.

What public liability doesn’t cover: damage to your own tools or property, your own injuries, or claims arising from poor professional advice (that’s what PI is for).

Professional Indemnity Insurance

If you give advice, make recommendations, or provide professional services that clients rely on, you need professional indemnity insurance — even if your profession doesn’t legally require it.

PI covers you if a client claims they suffered a financial loss because of your error, omission, or negligent advice. Think about it this way: if public liability covers physical damage, PI covers financial damage.

This matters for sole traders in a lot more industries than you might think:

A PI policy is typically written on a “claims made” basis, meaning it covers claims made during the policy period, regardless of when the work was done. This has an important implication: when you stop trading or retire, you should consider purchasing run-off cover, which extends protection for work done in the past. Without it, a claim could surface years later with no insurance in place.

What’s Optional (But Worth Considering)

Beyond the core two — public liability and professional indemnity — there’s a selection of covers that may or may not make sense for your situation. None of these are required, but all of them protect against risks that could be financially painful if you’re uninsured.

Business Property and Contents Insurance

If you work from home, don’t assume your home contents policy has you covered. Most standard home and contents policies specifically exclude or severely limit cover for business equipment. A separate business contents policy covers things like laptops, tools, stock, and office furniture against theft, fire, and accidental damage.

For sole traders with minimal equipment — say, a laptop and a phone — this might not be worth the premium. But if you’re a photographer with $15,000 worth of gear, a tradie with a full ute of tools, or a jeweller with stock on hand, the calculus changes completely.

Some insurers offer portable equipment cover as a standalone option or an add-on to a business pack, covering items you take between job sites. This is worth asking about specifically, because standard business contents cover sometimes only applies at your declared business address.

Income Protection Insurance

Income protection replaces a portion of your income (typically up to 70–75%) if you’re unable to work due to illness or injury. For sole traders, this is particularly important because there’s no employer sick leave to fall back on. If you can’t work, your income drops to zero.

Many Australians hold some level of income protection through their superannuation fund, but these default policies often have limitations: long waiting periods (90 days before benefits start), short benefit periods, and limited monthly benefits. An income protection policy held outside super can be customised with shorter waiting periods (14 or 30 days) and longer benefit periods, which makes it far more useful for a sole trader who needs to cover living expenses during a temporary inability to work.

The trade-off is cost. A standalone income protection policy for a sole trader can range from $500 to $2,000+ per year depending on your age, occupation, waiting period, benefit period, and monthly benefit amount. Premiums are also generally tax deductible, which takes some of the sting out.

Personal Accident and Illness Insurance

Personal accident and illness cover is a simpler, often cheaper alternative to full income protection. It pays a lump sum or weekly benefit if you’re injured or fall seriously ill, but the definitions of what qualifies for a claim are narrower than income protection. It’s commonly sold as part of business insurance packs aimed at tradies and manual workers, sometimes bundled with public liability.

This can be a cost-effective option if full income protection feels too expensive. Just read the definitions carefully — some policies only cover accidental injury, not illness, while others include both.

Tool Insurance

If you’re a tradie, your tools are your livelihood. Tool insurance covers portable tools and equipment against theft and accidental damage, whether they’re on-site, in your vehicle, or at home. Some policies also include cover for hired-in equipment, which can be useful if you occasionally rent larger gear for specific jobs.

Tool cover is often available as an optional extra on a trades insurance package rather than a standalone policy. Premiums vary based on the total value insured, but for $5,000–$10,000 worth of tools, you might pay $200–$500 per year — cheap peace of mind given that a single tool theft can easily run into thousands of dollars.

Cyber Insurance

If you handle client data — and these days, that covers almost everyone — cyber insurance is worth a look. It covers costs associated with data breaches, hacking, ransomware attacks, and business interruption caused by cyber incidents. For a sole trader, this might cover the cost of notifying affected clients, engaging forensic IT support, and managing reputational damage.

Cyber insurance for sole traders is relatively new and not all insurers offer it as a standalone product, but some providers include basic cyber cover as part of a business pack. Premiums are modest — often $300–$700 per year for sole traders — but coverage limits can be low, so check what you’re actually getting.

Industry-Specific Insurance Requirements

The insurance you need depends heavily on what you actually do for a living. Here’s how it breaks down by some of the most common sole trader categories.

Tradies

If you’re a builder, electrician, plumber, carpenter, plasterer, painter, or any other hands-on trade, public liability insurance is your non-negotiable starting point. Most tradies carry $10 million or $20 million in cover, and your state licensing body may set a specific minimum.

Builders face an extra layer of requirements. In most states, registered builders must hold home warranty insurance (also called home indemnity insurance or builders warranty insurance) for residential work above a certain value — for example, over $20,000 in Victoria. This protects homeowners if you can’t complete the job or fix defects because of death, disappearance, or insolvency. This is distinct from public liability and is obtained on a per-project basis.

Electricians, plumbers, and gasfitters often need public and products liability insurance to meet licensing requirements. Some states also require professional indemnity for certain licensed trades where design or certification work is involved.

If you’re a tradie who carries tools, tool insurance is a sensible add-on. And if your ute or van is critical to getting the job done, check that your motor insurance explicitly covers business use — standard personal cover may leave you exposed.

Consultants and Freelance Professionals

If you’re a business consultant, marketing strategist, IT contractor, graphic designer, or any kind of knowledge worker, professional indemnity insurance should be your first priority. Your clients are paying for your expertise, and if they believe that expertise fell short and cost them money, PI is what protects you.

Public liability remains worth having — even if you mostly work from home, the moment you visit a client’s office, attend a conference, or have a client visit you, you’re exposed to third-party injury or property damage risk. The premium is low enough for low-risk desk-based work that it’s hard to justify skipping it.

Cyber cover is particularly relevant for this group, since you’re almost certainly handling client data, login credentials, or confidential documents. A laptop theft or email compromise could expose client information and create a liability headache.

Health and Wellness Professionals

If you’re a physiotherapist, chiropractor, nutritionist, counsellor, personal trainer, or massage therapist, your insurance needs sit at the intersection of physical risk and professional advice risk.

Professional indemnity is essential — your clients rely on your clinical or professional judgment, and mistakes (or claims of mistakes) can have serious consequences. Most professional associations in the health space set minimum PI requirements for members, and some are high: $20 million is not uncommon for allied health professionals.

Public liability and products liability are equally important if you have a physical practice location or if you use equipment, supplements, or treatment products. If a client slips in your clinic or has an adverse reaction to a product you recommended, you’ll want cover in place.

If you’re registered with AHPRA, check your profession’s registration standards — some explicitly require professional indemnity insurance as a condition of ongoing registration.

What You Can Expect to Pay

Insurance premiums for sole traders vary widely by industry, revenue, location, and claims history, but here’s a rough sense of the market for a sole trader with no claims history operating in a metro area.

General guidance only. Premiums depend on your individual circumstances, the insurer, and the specific policy terms. Always get a quote for your own situation.

For public liability, sole traders in low-risk occupations (consulting, office-based work, creative professions) can typically find cover starting around $400–$600 per year for $10 million in cover. Trades and manual occupations sit higher — electricians and plumbers might pay $600–$900, while builders and structural trades can see premiums in the $800–$1,200 range for the same cover level, reflecting the higher risk of property damage claims.

Professional indemnity insurance for sole traders generally starts around $800–$1,200 per year for $1 million in cover for lower-risk professions like IT consulting or graphic design. Higher-risk professions — financial advisers, engineers, architects, health professionals — can see premiums in the $1,500–$2,500+ range, often with higher mandatory cover limits.

Bundling policies brings the total cost down. A combined public liability and professional indemnity package commonly costs less than buying each policy separately. Some insurers offer business packs that bundle public liability, business contents, and personal accident into a single policy with a single renewal date, which can simplify admin and reduce the overall premium compared to standalone policies.

How to Keep Your Premiums Manageable as a Sole Trader

Insurance is a cost of doing business, but that doesn’t mean you should pay more than necessary. Here are the levers you can pull to keep your premiums reasonable.

Pay annually rather than monthly. Most insurers charge a premium loading for monthly instalments — essentially, they’re financing your premium and charging interest for the privilege. Paying annually in one lump sum avoids this loading and can save you 10–15% on the total cost. If cash flow is tight, set aside a monthly amount in a separate account so you’re ready when renewal comes around.

Choose a higher excess. Your excess is the amount you pay out of pocket when you make a claim. A higher excess means a lower premium. For sole traders, the trade-off is usually worth it: insurance is there for the big, business-threatening claims, not the small stuff. If you can comfortably cover a $1,000 or $2,000 excess, bumping it up from the default $500 can trim a meaningful amount off your annual premium.

Bundle where it makes sense. As mentioned above, a business pack that combines public liability, business contents, and other covers will often be cheaper than buying each policy from different insurers. It also means one renewal date to keep track of, which reduces the chance of accidentally letting cover lapse.

Compare before you renew. It’s easy to let a policy auto-renew year after year, but loyalty doesn’t tend to be rewarded in insurance. Comparing quotes at renewal time — not just the premium, but what’s actually covered — can surface better options. If you use an online comparison platform, you can see multiple quotes side by side and check whether you’re still getting a competitive deal.

If you’re ready to see what’s available, you can compare quotes from a panel of insurers through BizCover. It takes about 10 minutes, and you’ll get multiple quotes without having to fill out separate forms for each insurer.

Don’t over-insure. There’s no point paying for $20 million in public liability cover if every contract you sign only requires $5 million or $10 million. Similarly, don’t insure $50,000 worth of tools if you own $15,000 worth. Match your cover to your actual exposure, not to a worst-case scenario that has no realistic chance of occurring.

Check your industry association. Many professional and trade associations have negotiated group insurance schemes for members. These can offer rates that are difficult to match on the open market. The membership fee might pay for itself in insurance savings alone, plus you get the other benefits of membership.

Maintain a clean claims history. This isn’t a quick fix, but it’s the most reliable way to keep premiums down over time. Insurers price risk based on claims history, and a sole trader with five years of no claims will generally pay less than someone with recent claims. This doesn’t mean avoid claiming when you genuinely need to — that’s what insurance is for — but it does mean being selective about whether a small incident is worth claiming or better handled out of pocket.

When Insurance Becomes False Economy

There’s a flip side to keeping costs down: being underinsured can cost you more in the long run than the premium you saved. Before you decide to skip a policy or go with the absolute cheapest option, ask yourself these questions:

The goal isn’t to insure against everything. It’s to identify the two or three risks that would genuinely threaten your business or your personal finances, and put cover in place for those.

Frequently Asked Questions

Do I need business insurance if I only work from home?

It depends on what you do. If you never visit clients, never have clients visit you, and your work involves no physical risk to third parties, public liability may feel optional — but professional indemnity might still be essential if you provide advice or professional services. Also check your home contents policy: standard policies rarely cover business equipment adequately. At minimum, talk to your home insurer about adding a business equipment rider.

Can I claim business insurance premiums on tax?

Yes. Business insurance premiums — including public liability, professional indemnity, business contents, and income protection held outside super — are generally tax deductible as a business expense for sole traders. Keep your policy documents and receipts, and confirm with your accountant that your specific policies qualify for the deduction.

What happens if I let my insurance lapse?

If your policy expires and you haven’t renewed, you’re uninsured from that moment. Any incident that occurs during the gap is not covered — even if you renew the next day. For claims-made policies like professional indemnity, a gap can be especially problematic because you lose continuity of cover, which can affect whether past work remains protected. If you’re switching insurers, make sure the new policy starts before or on the same day the old one ends.

How much public liability cover do I actually need?

For most sole traders, $10 million is the practical minimum. It satisfies the vast majority of commercial contracts, venue requirements, and council permits. If you work on government projects or large commercial sites, you may need $20 million. Check a few recent contracts you’ve signed — the required cover level will be stated there, and that’s your answer.

Is business insurance the same as personal indemnity insurance?

No. “Business insurance” is a broad term covering multiple types of cover — public liability, professional indemnity, business contents, and others. Professional indemnity insurance is one specific type of business insurance that covers claims arising from your professional advice or services. When someone asks if you have “business insurance,” they’re usually asking about public liability specifically, but it’s worth clarifying what they mean.
