NZ Company IRD Tax Audit: What New Directors Need to Know in 2026

Can a New Company Get Audited by the IRD?

Yes. The Inland Revenue Department (IRD) in New Zealand audits businesses of all sizes, including newly incorporated companies. While brand-new companies are not the primary audit target, they are at risk if they show certain red flags from the first GST return onwards.

Understanding what triggers IRD attention and how to keep clean records from day one is one of the most practical things a new director can do to protect the business.

What Triggers an IRD Audit

IRD uses a risk-based approach to select audit targets. Common triggers for new companies include:

• Large GST refunds in the first return: A new company claiming significant GST refunds before it has declared meaningful income is a pattern IRD notices.
• Cash-heavy industries: Hospitality, trades, retail, and personal services businesses deal in cash and are historically under-reported. These industries face higher audit rates.
• Income not matching lifestyle or industry norms: IRD uses benchmarking data. If a construction company reports margins far below the industry average, it is a flag.
• Missing returns or late filing: Companies that file late or miss GST, PAYE, or income tax returns are flagged in IRD systems.
• Discrepancies between GST returns and income tax: If your GST-inclusive income does not reconcile with your income tax return, the mismatch is detectable.
• Director-shareholder current account issues: Loans from the company to directors without proper documentation create FBT and income tax exposure.

How to Protect Yourself from Day One

The best time to set up clean records is before you start trading. Habits formed in the first 30 days are the ones that persist. Practical steps:

• Open a separate business bank account immediately: Never mix personal and company transactions. IRD auditors look for personal expenses claimed as business costs.
• Register for GST if your turnover will exceed NZ$60,000: Late registration creates back-dated liability. Consider voluntary registration if you have significant early expenses.
• Record every transaction: Cloud accounting software (Xero, MYOB) that connects directly to your business bank account makes this automatic.
• Document director-shareholder loans: If you advance money to or from the company, document it with a loan agreement and charge the correct interest rate. FBT and income tax apply to interest-free director loans.
• Keep GST invoices: Every GST claim requires a valid tax invoice showing the supplier's GST number, date, description, and amount.

What Happens During an IRD Audit

An IRD audit typically begins with a written notice requesting specific records. For a small new company, this might be a desk audit (reviewing documents sent to IRD) rather than a full field audit. The IRD will typically request:

• Bank statements for the audit period
• Sales invoices and income records
• Purchase invoices for claimed GST and deductions
• Vehicle logbooks if vehicle expenses are claimed
• Employment records if PAYE is involved

If IRD finds errors, they may adjust your returns and apply use-of-money interest and shortfall penalties. Penalties range from 20% (for not taking reasonable care) to 150% (for evasion).

When to Involve Your Accountant

If you receive any correspondence from IRD that goes beyond a routine information request, involve a qualified accountant or tax agent immediately. Do not respond to IRD audit notices without professional guidance.

The right time to find an accountant is before you receive an IRD notice, not after. A good accountant will set up your systems correctly from day one, review your first GST return, and be on file as your tax agent so IRD contacts them directly.
