A Revenue audit in Ireland is the formal examination of your tax returns and the records behind them to confirm the right amount of tax was paid. Most are routine, selected by Revenue’s risk-profiling system rather than because you have done anything wrong, but the letter still lands like a shock. This guide explains what an audit involves, how far back Revenue can look, and the practical steps to prepare so the process is calmer and the outcome better.
What a Revenue audit actually is
An audit is one point on a scale of Revenue interventions. At the lighter end are aspect queries and profile interviews, where Revenue asks about a single item or sits down to discuss your affairs. An audit is more structured: an authorised officer examines your books and records for one or more tax heads, including income tax, corporation tax, VAT, PAYE/PRSI, RCT or capital gains tax, over a defined period.
The most serious intervention is a Revenue investigation, which is reserved for cases where Revenue suspects deliberate evasion or fraud. An investigation carries higher penalties, the loss of certain protections available in an audit, and in the most serious cases the risk of prosecution. The vast majority of businesses will only ever encounter a routine audit, not an investigation.
You will normally receive written notice of an audit, usually giving at least 21 days before the audit date and setting out the tax heads and periods under review. That notice period matters, because it is your window to get your records in order and, crucially, to make a qualifying disclosure if one is warranted.
How far back can Revenue go
A common first question is how far back a Revenue audit can reach. In ordinary circumstances Revenue’s review is confined to a limited number of recent years, in line with the standard time limits for raising assessments. Where Revenue suspects fraud or neglect, however, those time limits fall away and Revenue can look back much further. This is one of the main reasons to take an audit seriously from the outset rather than assuming older years are off-limits.
Because the precise time limits and the way they apply can vary with the circumstances, it is always worth confirming your specific position with us or with Revenue before assuming how many years are in scope.
The notice period: your most important window
The gap between receiving the audit notice and the audit itself is the single most valuable part of the process. Once a Revenue audit notice issues for a given tax and period, you can no longer make an unprompted qualifying disclosure for that area, but a prompted qualifying disclosure may still be available in the notice window, and it can substantially reduce penalties and remove the risk of publication or prosecution.
A qualifying disclosure is a complete and accurate account of any tax you have underpaid, together with the tax and statutory interest. Getting this right is technical, and the difference between a disclosure that qualifies and one that does not can be significant in euro terms. This is the moment to take professional advice rather than to act alone. Our Revenue audits and investigations service exists precisely for this window.
Getting your records in order
Whether or not a disclosure is on the table, the practical groundwork is the same. Revenue will expect to see organised, reconciled records. Before the audit, work through the following:
- Bank reconciliations for every business account, with any personal lodgements or drawings clearly explained.
- Sales and purchases fully recorded, with invoices and receipts that match the figures on your returns.
- VAT records reconciled to your filed VAT returns, including the treatment of any property transactions, imports or reverse-charge items.
- Payroll records showing that PAYE, PRSI and USC have been operated correctly in real time, in line with PAYE Modernisation.
- Director and owner transactions, loans, expenses and benefits, documented and treated correctly.
- Cash businesses in particular should be ready to show that takings are complete, as cash handling attracts close attention.
Reconcile your returns to your underlying records and identify any differences before the auditor does. If you find an error, you want to be the one raising it, not explaining it after the fact. Solid year-round compliance and taxation services make this stage far less stressful, because the records already stand up to scrutiny.
On the day of the audit
The audit usually takes place at your premises or your accountant’s office. The officer will review records, may ask to interview you or your bookkeeper, and will want to understand how your business operates. A few principles help:
- Be cooperative, professional and prompt with information. Cooperation is a factor Revenue weighs when settling a case.
- Answer the questions asked, accurately and no more. Do not speculate or volunteer guesses about matters you have not checked.
- Keep a note of what is discussed and what is requested, so there is a clear record on both sides.
- Have your adviser present. You are entitled to representation, and having someone who understands both your affairs and Revenue’s procedures changes the dynamic of the meeting.
Penalties, interest and settlement
If an audit finds an underpayment, the settlement typically has three parts: the tax due, statutory interest for the period it was outstanding, and a tax-geared penalty. The size of the penalty depends on the taxpayer’s behaviour, broadly, whether the default was careless or deliberate, and on the level of cooperation and disclosure. A genuine, well-prepared qualifying disclosure with full cooperation attracts the lowest penalties and keeps your name off Revenue’s quarterly list of tax defaulters.
This is why preparation pays for itself. The same underpayment can produce very different outcomes depending on how the audit is handled and whether a disclosure was made in time. Because penalty rates, interest and the publication and prosecution thresholds are set in legislation and can change, treat the figures above as the framework rather than the detail, and confirm the current position with us or Revenue.
Do not ignore the letter
The worst response to a Revenue audit notice is to do nothing and hope. The notice period is short, the disclosure window closes quickly, and the decisions you make in the first days shape the whole process. Even if you believe your affairs are in perfect order, a quick review by an adviser gives you certainty before you walk into the room.
