A Revenue audit checks whether tax and returns are correct. Keep the notice, rental records, supporting invoices and calculations together, and respond through the appropriate process. A disclosure, enquiry and audit can have different procedural consequences; obtain advice on the actual notice.
Build an evidence index around the notice
| Focus | Action or question |
|---|---|
| Scope | Identify the taxes, periods and response dates actually stated. |
| Reconciliation | Match declared rent and deductions with bank records, invoices and tenancy information. |
| Response | Give your tax adviser the discrepancy list and notice so explanations address the enquiry rather than an unrelated property history. |
What a Revenue property income audit covers
Revenue may review property income as part of a general compliance check, a targeted enquiry or a more detailed audit. The review can relate to rental income from a house, apartment, room or holiday property, as well as income from commercial property or other arrangements. Revenue may compare information from tax returns with records available to it, including information supplied by letting agents, tenants or other parties. A review does not automatically mean that wrongdoing has been alleged, but it should be treated seriously and answered within the stated timeframe.
The central questions are usually whether all taxable property income was reported, whether the correct person reported it and whether deductions were supported by evidence. Rental income, allowable expenses and ownership records are likely to be important, particularly where a property is jointly owned or changed use during the year. Revenue may also examine whether income was received in cash, through a bank account, by a letting agent or through a short-term letting platform. The tax treatment can differ depending on the type of property, the use of the property and the owner’s wider circumstances.
A Revenue letter should explain the period under review, the information requested and the deadline for replying. Read it carefully before sending documents, because the scope may be limited to particular years or issues. If the request is unclear, an owner can seek clarification through the appropriate Revenue channel or ask a tax adviser to help interpret it. Keep a copy of the letter, the response and every document supplied, with a record of when information was sent.
Records and evidence Revenue may request
Good records should show how each figure in a property income return was calculated. Typical evidence includes tenancy agreements, rent schedules, bank statements, letting-agent statements, invoices, receipts, insurance documents and records of repairs. Owners should also retain documents showing mortgage interest or other finance costs where relevant, but should not assume that every borrowing cost is deductible in every situation. Separate records for each property make it easier to explain income and expenses, especially when several properties are owned.
A useful audit file contains a property-by-property income and expense schedule that reconciles to bank receipts and the figures included in the tax return. For example, if an agent collected rent, the gross rent may need to be shown before fees are deducted, with the agent statement supporting both amounts. Where a property was vacant, occupied by a family member or used partly for private purposes, keep evidence of the dates and the reason for the change. Missing records do not necessarily decide the outcome, but unsupported estimates are more difficult to defend.
Revenue may ask how an expense relates to the rental activity and whether it was a revenue repair or an improvement. A repair that restores an existing feature is generally analysed differently from a substantial improvement or extension, which may be treated as capital expenditure rather than an immediate deduction. Apportionment may be needed where a cost relates partly to private use, several properties or a period before letting began. Do not recreate receipts or alter old records; explain honestly what is available and how any calculation was made.
How to respond to an audit
Start by assembling the records in the order requested and prepare a short schedule explaining each property, its ownership, the periods it was rented and the income declared. Check that rent shown in bank statements agrees with tenancy or agent records, allowing for timing differences and fees. Review expense claims for duplicates, personal costs and items that may have been capital rather than revenue in nature. If an error is found, do not ignore it; obtain appropriate guidance on whether a correction or disclosure is required.
The most important practical points are the response deadline, complete disclosure and clear supporting evidence. A reply should answer each question directly and identify any document that is unavailable rather than sending a large, unorganised bundle. If records are held by a former agent, accountant or bank, request them promptly and tell Revenue if more time is needed. Delays, unexplained omissions or inconsistent figures can make a review more difficult, even where the underlying mistake was accidental.
An owner can deal with Revenue directly, but professional assistance may be sensible where several properties, joint ownership, foreign income, inheritance, a company or earlier undeclared income is involved. A registered tax adviser can help establish the correct position and communicate with Revenue, but the owner remains responsible for ensuring that information provided is accurate. Depending on the findings, Revenue may agree amended figures, seek additional tax and interest, or consider penalties under the applicable rules. The consequences depend on the facts, the quality of the disclosure and the relevant tax legislation.
Property tax issues beyond rental income
A property audit may bring other tax questions into focus, particularly where a property was bought, inherited, gifted or sold. Principal private residence relief explained in general terms means that relief from capital gains tax may be available for a qualifying person’s main home, but the result can be affected by periods of letting, absences, ownership arrangements and use of other parts of the property. Relief is not automatic simply because an owner lived in the property at some point. Revenue’s current guidance should be checked before relying on an exemption or relief.
For a gifted property, market value and connected-party rules can be important even where no money changes hands. Stamp duty on a gifted property may arise because a gift can be treated as a transfer for stamp duty purposes, with the precise treatment depending on the property, the relationship between the parties and other legal facts. Capital acquisitions tax or capital gains tax may also need consideration, and the person giving and the person receiving the property may have different obligations. A solicitor and registered tax adviser should confirm the position before a transfer is completed.
Borrowing and housing support can create a separate set of eligibility questions. Someone considering a Local Authority Home Loan should check the current income, residency, property, deposit and mortgage-refusal requirements directly with the relevant local authority, as eligibility rules and documentation can change. A Revenue audit does not itself establish eligibility for a loan, and any tax issue should be resolved independently of an application where possible.

Common mistakes to avoid
One common mistake is reporting only the amount that reaches a bank account after an agent’s fee, rather than keeping a clear record of the gross rent and the fee separately. Another is treating a deposit as income immediately in every case, even though its treatment may depend on whether it is refundable and how it is applied. Owners also sometimes overlook smaller payments, insurance proceeds or income from short-term accommodation. A complete annual reconciliation can identify these issues before Revenue asks questions.
A second mistake is claiming every property-related bill as an expense. Private costs, capital improvements and unsupported estimates require particular care because a property owner may pay for them from the same account used for rental activity. A new kitchen, structural alteration or extension should not automatically be described as a repair, while a personal broadband bill may not be wholly connected with letting. Keep a written explanation for unusual items and use a fair, documented method where a cost must be apportioned.
Finally, do not assume that a property used as a home is outside all tax considerations. A room let in a main residence, a property inherited and later rented, or a home that was rented before sale can each have different rules. Keep dates showing acquisition, occupation, letting, vacancy and disposal, together with contracts and professional valuations where relevant. Current thresholds, reliefs, filing dates and penalty provisions should be checked on revenue.ie rather than taken from an old return or online summary.
