Understanding IRD Audits in New Zealand
The Inland Revenue Department (IRD) is responsible for administering New Zealand’s tax system. One of its key responsibilities is ensuring taxpayers comply with tax laws and report income accurately.
When inconsistencies appear in financial records or tax filings, Inland Revenue may conduct an audit or investigation. These audits can apply to both individuals and businesses.

Common Triggers for an IRD Audit in New Zealand
1. Large Differences Between Reported Income and Industry Benchmarks
Inland Revenue often compares businesses with industry averages. If a business reports significantly lower income than similar businesses in the same industry, it may trigger further review.
For example, a restaurant reporting extremely low revenue compared to similar restaurants may attract attention from Inland Revenue.
2. Frequent Business Losses
Occasional losses are normal for businesses, especially in the early stages. However, reporting losses for several consecutive years may trigger scrutiny from Inland Revenue.
Authorities may review whether the business is operating genuinely for profit or if expenses are being incorrectly claimed.
3. GST Reporting Errors
GST returns are one of the most common areas where Inland Revenue identifies discrepancies.
Issues that may trigger audits include:
- Large GST refund claims
- Frequent amendments to GST returns
- Sales and expense figures that do not align
4. Overdue Tax Returns
Late or missing tax returns can increase the risk of an Inland Revenue investigation. If taxpayers repeatedly fail to file returns, Inland Revenue may review financial records to determine whether tax obligations have been met.

5. Unusual Expense Claims
Claiming expenses that appear unrelated to business operations may raise concerns.
Examples include:
- Personal expenses recorded as business costs
- Excessive travel or entertainment expenses
- Large deductions that do not match revenue levels
6. Information from Third Parties
Inland Revenue receives financial information from multiple sources, including employers, banks, and financial institutions. If this information does not match tax filings, it may trigger further review.
Types of IRD Audits
Risk Review
A preliminary review where Inland Revenue requests additional information to clarify discrepancies.
Desk Audit
A document-based review where Inland Revenue examines financial records submitted electronically.
Field Audit
A detailed investigation where Inland Revenue may review financial records in person or conduct interviews with the taxpayer.
What Happens During an IRD Audit?
If Inland Revenue initiates an audit, taxpayers will usually receive a notification letter explaining the review process.
The audit process may involve:
- Requests for financial documents
- Review of bank statements and tax filings
- Questions regarding transactions or deductions
- Assessment of tax liabilities
If discrepancies are identified, Inland Revenue may require adjustments, additional tax payments, or penalties.
