What is this right?
Revenue may conduct an audit of your tax affairs to check that your returns are correct. An audit involves a detailed examination of your books, records, and tax returns.
- You will normally receive written notification of an audit at least 21 days in advance.
- The notification will state the tax types and periods to be examined.
- Revenue distinguishes between different levels of intervention: aspect queries (focused on one issue), profile interviews, and full audits.
If an audit finds underpaid tax, you may owe the tax, interest (at 0.0219% per day, roughly 8% per year), and possibly penalties.
When does it apply?
- Revenue selects cases for audit based on risk analysis, random selection, third-party information, or specific intelligence.
- All taxpayers — individuals, sole traders, companies, trusts, and partnerships — can be audited.
- Revenue can go back 4 years for a standard audit, or unlimited years where there is fraud or deliberate non-compliance.
What to Do If Revenue Notifies You of an Audit in Ireland
- Don't panic — an audit notification is not an accusation. Many audits result in no additional liability.
- Appoint a tax advisor — you have the right to professional representation. An experienced accountant can manage the process.
- If you know your returns contain errors, consider making a qualifying disclosure before the audit starts — this significantly reduces penalties.
- Cooperate fully — provide the records requested within the timeframe given.
- You must keep adequate records for 6 years (individuals) or 6 years from end of the accounting period (companies).
What should you NOT do?
- Don't ignore the audit notification — non-cooperation increases penalties and can lead to a more aggressive investigation.
- Don't destroy records — this is a criminal offence.
- Don't make false statements — providing incorrect information during an audit can lead to criminal prosecution.
