Business Insurance — New Zealand Tax Rules

Claim professional indemnity, public liability, and other business insurance premiums as deductible NZ business expenses.

Claimable: Fully claimable · Tax authority: Inland Revenue

Inland Revenue Rules

• Professional indemnity insurance protecting you against client claims arising from your advice or services is fully deductible.
• Public liability insurance is fully deductible.
• Business vehicle insurance is claimable at the business-use proportion of the vehicle.
• Business equipment and asset insurance is fully deductible.
• Income protection (loss of earnings) insurance premiums are generally deductible — but the treatment depends on whether the policy replaces taxable income; confirm with your accountant.
• Personal insurance — life cover, private health, home and contents — is NOT deductible as a business expense.

Limits

No cap — all genuine business insurance premiums are fully deductible. Personal insurance products are never deductible.

Record Keeping

• Keep your accountant's confirmation on the deductibility of income protection if applicable

Frequently Asked Questions

Is income protection insurance deductible for the self-employed in NZ?

Generally yes — income protection (loss of earnings) insurance premiums are deductible if the policy replaces taxable business income. The flip side: any payout received under such a policy is taxable as income. The tax treatment depends on the policy structure, so confirm with your accountant.

Can I claim vehicle insurance as a business expense?

Yes, if the vehicle is used for business. Claim the business proportion of the annual insurance premium using the same method as your vehicle expenses — either the km-rate method proportion or your logbook business-use percentage.

Is cyber liability insurance deductible for NZ sole traders?

Yes. Cyber liability insurance protecting your business against data breaches, ransomware attacks, and cyber incidents is a fully deductible business insurance premium. This is increasingly relevant for self-employed professionals who hold client data.

Can I claim health insurance as a business expense?

No. Personal health insurance covering your own medical costs is not deductible as a business expense in New Zealand, even if you argue that being healthy helps you work. Only business-purpose insurance — professional indemnity, public liability, business assets — is deductible.

How do insurance premiums affect my Provisional Tax, and where do I enter them in myIR?

Insurance premiums reduce your taxable net profit, which lowers your Residual Income Tax (RIT) and therefore your Provisional Tax instalments. In myIR, enter all deductible insurance costs in the 'Expenses' section of your IR3. If your income protection policy has specific deductibility rules (confirmed by your accountant), include only the qualifying portion. Keep all insurance invoices and policy documents as supporting records.
