Every dollar you spend running your business counts, and insurance is no exception. If you’re paying for public liability, professional indemnity, or any other policy that keeps your business protected, you want to know whether those premiums are tax deductible. The short answer: in most cases, yes. But the detail matters, and getting it wrong can cost you at tax time — or worse, trigger an ATO review.
This guide walks through exactly what you can claim, what you can’t, how GST works on insurance premiums, the paperwork you need to keep, and the common traps that catch business owners out. It’s general information only — always speak to a registered tax agent or accountant for advice specific to your situation.
The core principle: Is it directly related to earning assessable income?
The ATO’s rule is straightforward. Under section 8-1 of the Income Tax Assessment Act 1997, you can claim a deduction for any expense incurred in gaining or producing your assessable income, as long as it’s not private or domestic in nature.
In plain English: if you’re paying for an insurance policy that protects your ability to earn business income, you can generally deduct it. If the policy covers something unrelated to your business — or purely personal — the deduction gets more complicated or disappears entirely.
The key question to ask yourself: would I still need this policy if I didn’t run this business? If the answer is yes, it’s probably deductible. If the answer is no, look closer.
This principle applies regardless of your business structure. Sole traders, partnerships, companies and trusts all follow the same logic — the difference is whose tax return the deduction lands on, and which entity pays the premium.
Insurance types that are fully deductible
Most standard business insurance policies meet the ATO’s test without ambiguity. The following policies are generally fully deductible in the year you pay the premium.
Public liability insurance
Public liability covers you if a third party — customer, supplier, or member of the public — is injured or suffers property damage because of your business activities. It’s a non-negotiable policy for tradies, retailers, event operators and anyone who interacts with the public. Because the entire purpose is protecting your business from claims that could otherwise sink it, the ATO treats public liability premiums as fully deductible. If you’ve taken out a packaged policy bundling public liability with other business covers, the whole premium is generally deductible — just make sure there isn’t a personal component mixed in.
Professional indemnity insurance
If you provide advice, designs, consulting, or any professional service where a mistake could cost your client money, you probably hold professional indemnity insurance. Doctors, lawyers, architects, accountants, IT consultants, marketing agencies — the list of professions relying on PI cover is long. The ATO treats these premiums as an operating expense incurred directly in earning assessable income. Deduct them in full. Run-off or retroactive cover doesn’t change the tax treatment — the premium is still deductible when paid.
Workers’ compensation insurance
Workers’ comp is compulsory in every Australian state and territory once you have employees, and in some states it’s required even for sole traders or directors. Because it’s a legal requirement to operate your business, it’s fully deductible. If you’re a sole trader who has taken out workers’ comp to cover yourself — required in certain states for specific industries — that premium is still a business expense, not a personal one.
Business property and contents insurance
Whether you’re insuring commercial premises, tools, equipment, stock, or portable items like laptops, business property insurance is a deductible expense. If you operate from home, consider listing your business gear on a dedicated business contents policy rather than relying on your home and contents insurance, which is primarily personal — this avoids apportionment complications.
Business interruption insurance
Business interruption (BI) cover replaces lost revenue and covers ongoing expenses when an insured event forces you to stop trading. You’re insuring the revenue stream itself, so the ATO sees BI premiums as squarely within the “gaining or producing assessable income” test. If your insurer has bundled BI with property insurance as a single premium, the whole amount is still deductible.
Cyber insurance
Cyber insurance covers data breaches, ransomware, business email compromise, and the resulting PR and legal costs. The ATO treats cyber premiums the same as any other business operating expense. If your business holds data, processes payments online, or relies on digital systems to generate revenue, it’s a cost of doing business — deduct it fully.
Management liability and theft insurance
Management liability (sometimes called D&O insurance) protects directors and officers for claims arising from their decisions — breach of duties, employment practices claims, regulatory investigations. The company typically pays the premium and claims the deduction. Theft and burglary cover, whether standalone or bundled into a business package, is also fully deductible — you’re protecting business assets used to generate income.
Insurance types with special rules
Not all insurance deductions are straightforward. A few policy types sit in a grey zone or have specific conditions. Get professional advice on these — the ATO does scrutinise them.
Income protection insurance — inside vs outside super
Income protection replaces a portion of your income if you’re unable to work due to illness or injury. The tax treatment depends on how you hold it.
Inside super: Premiums are paid by the fund from your super balance. The fund claims the deduction, not you. No action needed on your individual return.
Outside super: Premiums paid directly to an insurer are generally deductible under section 8-1, provided the policy replaces assessable income through monthly benefits. The ATO distinguishes between “income replacement” policies (deductible) and “trauma” or “critical illness” policies (generally not deductible unless held through super). If your income protection covers both business and personal income — say you’re a sole trader with a side job — the premium is still fully deductible as long as the policy’s primary character is protecting your income-earning ability.
Life insurance and key person insurance — generally not deductible
This is where many business owners get tripped up. Life insurance premiums, whether held personally or through the business, are generally not deductible. The ATO’s reasoning: life insurance is a capital protection measure, not a revenue expense. It protects your estate or family’s financial position, not your business’s day-to-day income. The same logic applies to TPD insurance bundled with life cover.
Key person insurance is the partial exception. If your business takes out a policy on a key person — a director, a critical salesperson, a technical specialist — and the business is both owner and beneficiary, the premiums may be deductible. The bar is high: you need a properly documented commercial arrangement demonstrating that the business suffers direct financial loss if the key person dies or is incapacitated. The ATO looks at the substance of the arrangement, not just what’s written on the application. Don’t DIY this — get specific advice from your accountant.
Insurance bundled with personal policies
If your home and contents policy covers your home office equipment, only the portion relating to business use is deductible. For example, if your premium is $1,800 and your business equipment makes up roughly 20% of the total insured value, you could reasonably claim $360 plus the GST component. Keep a record of how you calculated the split. A better approach: get a standalone business contents policy for your gear — it removes the apportionment headache entirely.
Who pays the premium matters
The entity that pays determines where the deduction appears.
Sole traders: You and your business are legally the same entity. Insurance deductions go in the business section of your individual tax return. Whether the premium comes from a personal or business account doesn’t matter for tax, though a separate business account simplifies record-keeping.
Partnerships: The partnership claims the deduction in its return; the net effect flows through to each partner’s individual return via their distribution. If a partner pays personally, they claim only to the extent of their partnership share.
Companies: The company claims the deduction. If a director pays personally and is reimbursed, the company claims the reimbursement as the expense, not the director.
Trusts: The trust carrying on the business claims the deduction. Deductions reduce the trust’s taxable income, flowing through to beneficiaries.
The general rule: the entity that incurs the expense and carries on the business gets the deduction. Don’t shift deductions between entities for a tax advantage — the ATO looks at who actually paid and who benefits from the cover.
GST on insurance premiums: get the detail right
GST on insurance confuses many business owners. Here’s what you need to know.
Most general insurance premiums in Australia include 10% GST. This covers public liability, professional indemnity, business property, business interruption, cyber, management liability, theft, and business motor vehicle insurance. Your insurer’s invoice will show the premium, GST, and stamp duty as separate line items.
When you’re registered for GST, you can claim input tax credits for the GST in your business insurance premiums — on top of claiming the premium itself as an income tax deduction. These are two separate things: GST credits go on your BAS, the income tax deduction goes on your tax return.
Life insurance premiums are GST-free, so there’s no GST credit to claim. Income protection held outside super is also generally GST-free — confirm with the product disclosure statement.
Stamp duty is not subject to GST. It’s a separate government charge. You can’t claim a GST credit on stamp duty, but the stamp duty itself is deductible as part of the overall insurance cost, assuming the policy is a deductible business expense.
State stamp duty rates vary: NSW sits around 9% for most business insurance, Victoria at 10%, Queensland at 9%, with other states between 8% and 11%. Your insurer’s invoice calculates these for you. The bottom line: your total insurance cost is premium plus GST plus stamp duty, and you can deduct the premium plus stamp duty while claiming GST credits on the premium portion only.
Record keeping: what the ATO expects
The ATO requires you to keep records explaining every deduction for five years from the date you lodge. For insurance, keep:
- Policy schedule or certificate of insurance — shows what you’re insured for, the policy period, premium amount, and the insured party.
- Tax invoice from your insurer — must show premium, GST, stamp duty, and total paid. GST-registered businesses need a valid tax invoice to claim GST credits.
- Proof of payment — bank statement, credit card statement, or receipt showing the entity claiming the deduction actually paid.
- Apportionment calculations — if you’ve split a premium between business and personal use, keep your working notes.
- Correspondence with your insurer — emails about policy changes, mid-year adjustments, or claims affecting premiums provide context if the ATO asks.
The ATO’s myDeductions app lets you photograph and categorise receipts on the go. It’s free and built for sole traders — a low-effort upgrade from the shoebox method.
Timing of deductions: when do you claim?
The general rule: you claim the deduction in the year you pay. Pay a 12-month PI policy in June 2026, claim the full amount in your 2025-26 return.
The prepayment rule
The ATO’s prepayment rules say if you prepay for a service extending more than 12 months, you can only deduct the portion relating to the current income year, with the rest spread forward. This almost never applies to standard business insurance, because policies are nearly always written for 12 months. A 12-month policy paid upfront is fully deductible in the year you pay. Multi-year policies (unusual, but possible for construction or project-based covers) require apportionment — talk to your accountant.
Cash vs accruals
Most sole traders and small businesses use the cash basis: deduct when you pay. On accruals accounting (more common for larger businesses), you deduct when the expense is incurred — typically when the coverage period begins, even if unpaid.
Renewals across financial years
A common scenario: your public liability renews every 1 July. In June 2026 you receive and pay the renewal invoice for 2026-27. The policy covers entirely the next financial year, but because you paid in 2025-26 and the policy period doesn’t exceed 12 months, you claim the deduction in your 2025-26 return. Perfectly legitimate.
Common ATO audit triggers
The ATO doesn’t publish a checklist, but tax professionals point to patterns that get insurance deductions flagged:
- Deductions large relative to income — data-matching algorithms flag returns where insurance costs look unusually high against reported income. Not necessarily wrong, but be prepared to substantiate.
- Claiming personal insurance as business — the most common mistake. Life insurance, personal TPD, and unapportioned home and contents insurance are not business deductions.
- Inconsistent claims year to year — if deductions jump 300% without an obvious reason (new employees, higher-risk industry), the ATO may ask questions. Keep a note explaining the change.
- Double-dipping — claiming the same premium through both your company and your personal return. The ATO’s pre-filling data often picks this up.
- Claiming GST credits without GST registration — you can only claim GST credits if registered for GST. Sole traders under the $75,000 threshold can still claim the full premium as an income tax deduction, just not the GST component separately.
- Insufficient records — if you can’t produce the policy schedule, tax invoice, or proof of payment when asked, the ATO can disallow the entire deduction.
State-based differences worth knowing
Beyond stamp duty rates, a few state-level differences affect insurance costs:
- Workers’ compensation is state-based. NSW uses icare, Victoria uses WorkSafe, Queensland uses WorkCover Queensland. If you employ staff across multiple states, you may need workers’ comp policies in each — all deductible, but track them separately.
- CTP insurance for business vehicles is state-based and usually bundled into registration. If paid separately and the vehicle is business-used, CTP is deductible alongside your comprehensive motor insurance.
- Home-based business requirements can differ by local council. Some councils mandate public liability cover for businesses with client visits — any council-mandated insurance is a deductible business expense.
Practical workflow for tax time
When June 30 rolls around, work through this sequence:
- Gather every insurance invoice from the financial year — renewals, new policies, mid-term adjustments. Include policies you paid personally that cover business assets.
- Match payments to invoices. Confirm you can connect each bank statement line to a specific tax invoice.
- Categorise each policy into three buckets: fully deductible, partially deductible (with business-use percentage noted), and not deductible.
- Calculate deductions by entity — make sure Company A’s return only claims what Company A paid.
- Prepare the BAS component separately — total the GST on all business insurance premiums for each GST-registered entity, excluding stamp duty.
- Keep digital copies — scan or photograph everything. Create a folder by financial year (e.g. “Tax > 2025-26 > Insurance”).
- Note unusual items — mid-year cancellations and refunds, new cover types, premium jumps. Write a short note for context.
If you use an accountant, having your documents organised before you walk in saves billable hours and reduces the chance of missed deductions.
Pro tip: Compare quotes before renewal to keep premiums manageable. If you haven’t checked the market, get quotes from multiple insurers via BizCover{target=“_blank” rel=“noopener”} — you might find the same cover for less, or confirm your current premium is already competitive.
What happens if you claim incorrectly?
If the ATO determines you’ve claimed a deduction you weren’t entitled to, they’ll issue an amended assessment. You’ll pay back the underpaid tax plus interest (currently around 8-11%, varying by quarter — check the ATO website).
If the ATO finds a failure to take reasonable care, they may add a penalty of 25% of the tax shortfall. Recklessness raises it to 50%. Intentional disregard — fraud — hits 75%.
The takeaway: be methodical, honest, and keep good records. If you’re unsure whether a policy is deductible, ask before you lodge. A tax agent’s fee is almost always less than the cost of getting it wrong. And if you spot a mistake in a past return, voluntarily disclosing it to the ATO before they contact you can significantly reduce penalties.
Frequently Asked Questions
Can I claim my home and contents insurance as a business deduction if I work from home?
Only the portion relating to business use. If your home and contents policy covers business equipment, apportion the premium based on the value of business assets relative to total insured value. You can’t claim the entire premium just because you have a home office. A separate business contents policy avoids the apportionment calculation entirely.
Is income protection insurance tax deductible if I’m self-employed?
Yes, if held outside super and paid personally. Income protection policies providing monthly benefits to replace lost income are generally deductible under section 8-1. If held through super, the fund claims the deduction. Trauma and critical illness policies are generally not deductible unless held through super — check with your accountant.
Can I claim a tax deduction for my car insurance?
Yes, apportioned between business and personal use. Under the logbook method, the same business-use percentage applies to comprehensive insurance, CTP, and registration. Under the cents-per-kilometre method, insurance is factored into the rate — don’t claim it separately.
Do I need to be GST-registered to claim insurance as a tax deduction?
No. GST registration affects whether you can claim GST credits, not whether the premium itself is deductible. If you’re not registered for GST, claim the full amount paid (including GST) as an income tax deduction. The $75,000 GST threshold applies to total turnover, not individual expense categories.
What happens if I cancel an insurance policy mid-year and get a refund?
Include the refund as assessable income in the year you receive it. If cancellation happens in a later financial year after you’ve already claimed the full amount, the refund becomes assessable income in that later year. Keep records of cancellations and refunds.
Can I claim insurance deductions for a business that hasn’t started trading yet?
In some cases, yes. The ATO allows deductions for pre-business expenses under section 40-880, provided the business has genuinely commenced — not just in planning stages. What constitutes “commencement” depends on your business type. Get specific advice from a tax professional if you’re incurring insurance costs before your first sale.
A final note on getting your insurance right
The tax treatment of business insurance is, for the most part, simple: if you need the insurance to run your business, it’s deductible. Complications only arise around the edges — personal-use apportionment, life insurance, and entity structure.
Remember: a tax deduction is useful, but it’s not the point of insurance. You’re buying protection against events that could end your business. The deduction is a bonus. Focus on getting the right cover at a competitive price, and the tax treatment follows naturally.
If you haven’t reviewed your business insurance in the last 12 months, comparing quotes across multiple insurers is quicker than you think. Start with an online quote through BizCover{target=“_blank” rel=“noopener”} — you’ll either find better cover for less or confirm you’re already on a good deal. Either way, you’ll make your next renewal decision with confidence.
