What is Tax Audit Insurance?
Tax Audit insurance covers accountant’s costs incurred in responding to an audit or investigation by the Australian Tax Office (ATO).
Being audited can be time consuming, complicated and potentially very costly. Tax Audit insurance can help take the stress out of these situations by paying accountant or bookkeeper fees related to an audit. It can have your back if a mistake in your BAS, VAT calculations, or tax return puts you on the ATO’s list. BizCover offers fast, secure, and customisable Tax Audit insurance built for small businesses.

What does Tax Audit insurance cover?
Tax Audit insurance can help small businesses cover professional fees related to an ATO audit. It may cover fees related to common auditing reasons, such as BAS/GST compliance, income and payroll tax, record keeping, superannuation compliance, and self-managed superannuation funds.

Why is Tax Audit insurance important?
The risk of potential audit is very real for Aussie businesses. A tax audit can be triggered by common events, such as discrepancies in tax returns or unusual financial activity. You could also be selected for audit at random.
Getting audited is not only stressful, but potentially expensive too. You may face additional costs in hiring an accountant or other tax professional to help manage the audit process.
Tax Audit insurance can provide important peace of mind that audit fees will be covered should the ATO decide to audit your business.

How is the cost of insurance calculated?
Risks of the industry
Cover level amount

Number of employees
Claims history
Get cover that grows with your business
You can insure your business with Tax Audit cover limits up to $50,000.
Unsure how much to choose? Think about:
Statutory professional requirements
Cover required by contracts
Worst case scenario claim size
Underinsurance
We know it’s tempting to select a lower level of cover to reduce premiums, but this can leave businesses shocked and insufficiently covered when making a claim.
Ways underinsurance catches business owners out:
Inflation
With inflation, the cost of living and doing business increases. Remember to over yourself, your tools and assets for the rising costs of replacing or covering them, not what you paid for them – you may be surprised at the difference.
Not covering the full cost of your risks
If you select cover levels for less than the value you may be found liable – left out of pocket when it comes to claims time. It’s important to review your risks and determine how much you will need to cover any claim that may come your way.

Tax Audit Insurance claim example
A beautician received a letter from the ATO that they were to be audited for the 2023-24 period. They engaged their own accountant to assist with the audit and advised their insurer of the circumstances.
The ATO found that the beautician had made some incorrect declarations and identified a tax shortfall after revising the activity statement. They decided not to penalise the beautician, only requiring that the tax shortfall be paid.
The beautician’s insurer reviewed the outcome of the audit and covered $2,230 in accountant’s fees related to it. However, the tax shortfall was not covered, as the amount would have been payable in the first instance had the tax return been lodged correctly.
