Frequently Asked Questions

What happens if you are audited by IRD in New Zealand?

If you are audited by IRD, the department will review your financial records in detail, including GST filings, PAYE returns, and supporting documents. They may cross-check your data with third-party sources such as banks and employers. If discrepancies are found, you may be required to pay penalties, interest, or additional tax.

How far back can IRD investigate?

IRD typically investigates up to four years from the date of filing. However, if there is evidence of serious fraud or tax evasion, the investigation period can extend beyond four years, allowing authorities to examine older financial records.

Can IRD access my bank account information?

Yes, IRD has the authority to access and review financial data, including bank transactions, to ensure that reported income and tax filings are accurate. This is often done through data-matching systems.

What are the penalties for tax evasion in New Zealand?

Penalties can include financial fines, interest on unpaid tax, repayment of outstanding amounts, and in serious cases, legal action such as prosecution or home detention. The severity depends on the level of non-compliance.

How do I know if IRD is investigating my business?

You may receive formal communication from IRD requesting information or clarification. Notices regarding discrepancies, audits, or documentation requests are often early indicators of an investigation.

Can small tax mistakes lead to penalties?

Yes, even small or unintentional errors such as incorrect expense claims or late filings can result in penalties if they are not corrected promptly.

What should I do if IRD contacts me?

You should respond promptly, gather all required documents, and consider seeking professional advice to ensure your response is accurate and complete.

How can I reduce my chances of an audit?

Maintaining accurate records, filing taxes on time, and conducting regular financial reviews can significantly reduce your risk of being audited.

What Businesses Should Do If They Find an Error

Discovering an error in your tax filings can feel stressful, but acting quickly can significantly reduce potential consequences.

The most important step is to avoid ignoring the issue. Delays often increase penalties and interest, making the situation harder to resolve over time.

Instead, businesses should take a structured approach:

• Review the issue in detail
  Identify whether the error relates to GST, PAYE, or income reporting. Understanding the root cause helps prevent repeat mistakes.
• Gather all supporting documentation
  Ensure you have accurate financial records, invoices, and bank statements ready. Clear documentation makes it easier to explain discrepancies if questioned.
• Consider voluntary disclosure
  In New Zealand, voluntarily informing the Inland Revenue Department about an error before an audit begins can reduce penalties. This demonstrates intent to comply.
• Seek professional guidance early
  Working with DFK Orb 360 can help you correct issues properly and ensure future compliance.

Taking proactive action not only reduces risk but also demonstrates responsibility, which can positively influence how your case is handled.

The Cost of Waiting vs Acting Early

Many businesses delay addressing tax issues because they believe the problem is minor.

However, small inconsistencies often grow into larger financial and legal risks over time.

Acting early helps you:

• Minimise penalties and interest
• Maintain business credibility
• Avoid escalation into audits or investigations

Waiting, on the other hand, can lead to:

• Increased scrutiny from IRD
• Higher financial exposure
• Reputational damage

The difference between a manageable issue and a serious problem often comes down to timing.

Stay ahead of compliance risks with expert support.
