Premium, Levies, Fees: How to Read an Australian Business Insurance Invoice

Say your quote is for a base premium of $4,000, and the invoice you’re asked to pay comes to $5,300. Or you receive a quote for $3,000++ - what does that ++ actually cover? Either way, your quoted premium is still in there. It’s just not the only line on the bill.

This insurance invoice breakdown walks through every line on an Australian business insurance invoice: base premium, emergency services levy, GST, stamp duty, broker fee, and the occasional premium funding charge. We’ll flag which lines are statutory (you can’t negotiate them) and which aren’t, drawing on a sample of around a hundred quote and policy documents from our own records.

The short answer

Your invoice is higher than the quoted premium because levies, GST, stamp duty and fees are added on top of the base premium. In that sample, where an emergency services levy appeared as its own line, the median was 9.1% of the recorded premium. Add 10% GST, state stamp duty and any broker fee, and the gap between “quoted premium” and “amount payable” adds up fast.

What are the lines on a business insurance invoice?

A typical invoice stacks five to six components: base premium, emergency services levy (in some states), GST, stamp duty, broker fee. Each one is calculated on the layers beneath it, which is part of why the total climbs faster than you’d expect.

Here’s the anatomy, in the order the maths is applied:

Line	What it is	Who sets it	Negotiable?
Base premium	The insurer’s price for the risk	Insurer	Yes, via remarketing or risk changes
Emergency services levy (ESL/FSL)	Funds fire and emergency services in NSW (TAS also levies via insurance)	State government sets the pool; insurers set their own recovery rate	Not directly, but the rate varies by insurer
GST	10% federal tax on premium plus levy, and on any broker fee	Federal government	No
Stamp duty	State tax on insurance, varies by state and product	State government	No
Broker fee / policy fee	The broker’s charge for the work on the account: placement, negotiation, renewal remarketing, mid-term changes and claims advocacy	Broker	Varies
Premium funding charges – usually a separate agreement	Interest and fees if you pay monthly via a funder	Premium funder	Partly (depending on the premium size, or pay annually)

The ordering matters. GST is charged on premium plus levy, and stamp duty is generally calculated on the premium including GST and levies, though the exact base varies by state. So a levy doesn’t just add its own cost, it inflates the taxes calculated after it.

That compounding is one reason the total looks greater than the initial base premium at times.

What is the emergency services levy?

The ESL (sometimes shown as FSL, fire services levy) is a state charge collected through insurance premiums to fund fire and emergency services. NSW is the main state still funding these services this way, and Tasmania also applies a levy through insurance. Several other states have shifted this funding to property-based charges.

It’s also a line that doesn’t always appear in the quote figure, which is why it can catch you at invoice time. Roughly two-thirds of the documents in our sample carried an explicit levy line. Across those, the median levy was 9.1% of the recorded premium, and the top quarter ran at roughly 11% or more.

Three caveats on that figure. We only counted levies shown as explicit line items, so any levy embedded inside a premium figure isn’t captured. The sample mixes products and jurisdictions, so your own rate depends on your state, your insurer and what you’re insuring. And a NSW commercial property risk can sit well above that median, because property carries the highest contribution rate of any class.

Property-heavy policies in NSW tend to feel it most. The mechanics of how NSW funds emergency services through insurance are explained on the Revenue NSW website.

Two things narrow where it shows up. It’s a state charge, so a business outside NSW and Tasmania may see no levy line at all. And it attaches by class of insurance: in NSW, property cover carries the highest contribution rate, motor a much smaller one, and a number of classes including theft and plate glass attract none. A liability-only policy generally won’t carry a levy line. Same business, different state or different product, different total.

That is the position as at 2026. NSW has emergency services levy reform under consideration, so it’s worth checking the current treatment at renewal.

How do GST and stamp duty work on insurance?

GST is a flat 10% applied to the premium plus any levy. Stamp duty is a state tax that varies by state and by product type, generally calculated on the premium including GST and levies, with the exact base varying by state. Both are statutory. No broker or insurer can reduce them.

GST is the easy one: if you’re registered for GST and the policy is for your business, the GST component is generally claimable as an input tax credit (more on that in the FAQ below).

Stamp duty is messier. Every state sets its own rates, and within a state, different classes of insurance can attract different rates, with some products exempt entirely. That’s why we won’t quote you a single percentage here: there isn’t one.

The practical takeaway is simpler. If you operate across multiple states, the same cover can produce different invoice totals depending on where the risk is located.

If a term on your invoice doesn’t ring a bell, our insurance glossary covers the jargon in plain English.

What’s the broker fee, and how is it different from commission?

Commission is paid to the broker by the insurer out of the premium, so it typically isn’t shown as a separate charge to you. A broker fee is charged directly to you and does appear as an explicit line on the invoice. They’re separate things, and a broker can receive one, the other, or both.

Not every invoice carries one. Where a broker is remunerated through commission alone, there’s no separate fee line to find.

Where there is one, it reflects the work on the account: scoping the risk, approaching the right insurers, negotiating terms and wording, handling mid-term changes, remarketing at renewal, and advocating when a claim is made. A risk that needs approaches to a dozen insurers carries a different workload to a straightforward renewal, and that is what a fee is meant to reflect.

You’re entitled to know how your broker is paid. Where you’re dealt with as a retail client, remuneration must be set out in the Financial Services Guide and any Statement of Advice (where required), whether or not you ask. Whatever the classification, you can always ask. Our piece on what a broker fee is and why brokers charge them goes through it properly.

The useful question isn’t whether there’s a fee. It’s what the fee is buying. A broker who remarkets your program, checks your sums insured and runs your claims is doing work that otherwise lands on you.

What are premium funding charges?

If you pay your annual premium in monthly instalments through a premium funder, the funder’s interest and fees are added on top of the invoice total. It’s effectively a short-term loan secured against the policy, which means that if you fall behind on instalments the funder can cancel the policy to recover the unearned premium.

Premium funding is genuinely useful when a lump-sum annual payment would strain cash flow, and for GST-registered businesses the timing of input tax credits can soften the cost. But it isn’t free, and the charges belong in your comparison when you weigh paying annually versus monthly. We’ve laid out how it works on our premium funding page.

Which invoice lines can you actually do something about?

Realistically two: the base premium, and which insurer you place with. GST and stamp duty are fixed by statute. The emergency services levy is a charge insurers recover at their own rate, so it can move when the risk is remarketed.

The base premium moves when the risk is remarketed, when your claims history improves, when you adjust excesses or sums insured, or when your risk profile changes. That’s the core of what a broker does.

The levies, GST and stamp duty follow the premium mechanically. Which points to the quiet win: every dollar cut from the base premium also cuts the taxes calculated on top of it. Reduce a NSW property premium by $1,000 and the saving at the invoice total is meaningfully more than $1,000 once the levy, GST and stamp duty stack shrinks with it.

If your renewal invoice has jumped and the lines don’t explain why, that’s a remarketing conversation. Our business insurance brokers page covers how we approach it, or you can go straight to get insured to start a quote comparison.

Frequently asked questions

Why does my invoice exceed the quoted premium?

A quoted premium is usually the base premium only. The invoice then adds any emergency services levy, GST, stamp duty and any broker fee. Among the documents in our sample that carried an explicit levy line, the median levy was 9.1% of premium, so the gap is structural, not an error. Plenty of policies carry no levy line at all, and a NSW property risk can run well above that. If the gap looks larger than these components explain, ask for a line-by-line breakdown. Your broker should be able to give you one.

Is the broker fee on top of commission?

It can be. Commission comes from the insurer out of the premium and usually isn’t shown as a separate line; the broker fee is charged to you directly and is visible. Some brokers charge both, some rebate commission and charge a fee only, some charge no fee. For retail clients, how a broker is paid must be set out in the Financial Services Guide you’re given before the advice, not only on request.

Is GST on business insurance claimable?

Generally, if your business is registered for GST and the policy relates to the business, the GST component can be claimed as an input tax credit on your BAS, and insurers will usually ask for your input tax credit entitlement when you take out the policy. There’s detail in the rules, particularly around claims payments, so confirm your position with your accountant. Moneysmart also has general guidance on insurance costs.

Do levies differ by state?

Yes, significantly. NSW is the main state still funding fire and emergency services through a levy on insurance, and Tasmania also levies through insurance, while several other states have shifted to property-based funding. Stamp duty rates also differ by state and product. Two identical businesses in different states can receive visibly different invoice totals for equivalent cover.

What is premium funding?

A loan that pays your annual premium upfront so you repay in monthly instalments, with interest and usually an application fee added. It smooths cash flow but increases total cost, so compare the funding charges against the value of holding onto your cash. Details on our premium funding page.

Renewal total jumped and the lines don’t explain it?

That’s worth looking at before you pay it. We review renewal terms, check the cover still matches the business, and take the risk back to market where the numbers justify it. Call Tank Insurance on 02 9000 1155 or email [email protected], or contact us online.
