The Annual Return of Trading Details, commonly referred to as the RTD, is a supplementary VAT declaration that every VAT-registered business in Ireland must file with Revenue each year. Unlike the regular bi-monthly VAT returns that capture short-term activity, the RTD provides a comprehensive annual overview of your total supplies, purchases, and VAT figures, enabling Revenue to cross-check the accuracy of your periodic filings against a single consolidated summary.
This return is filed using the Form RTD on the Revenue Online Service (ROS) and covers the 12-month period aligned with your accounting period. It serves as a reconciliation tool, ensuring that the cumulative figures from your bi-monthly or four-monthly VAT returns match the annual totals declared in the RTD. Any discrepancies between these figures will alert Revenue to potential errors or under-declarations that may require further investigation.
For founders and business owners, understanding the RTD is essential because it connects your day-to-day VAT activity with your broader tax compliance obligations. Filing it accurately and on time helps maintain your company's good standing with Revenue and reduces the risk of audits, penalties, or unexpected tax adjustments that could disrupt your cash flow.
Every person or entity registered for VAT in Ireland is required to file an Annual Return of Trading Details. This includes limited companies, sole traders, partnerships, and any other business structures that have been assigned an Irish VAT number by Revenue. The obligation applies regardless of whether you made supplies during the year or had a nil trading period.
Even if your company is dormant or has temporarily ceased trading, you must still file the RTD for any period during which you held a VAT registration. Failing to file can result in Revenue issuing estimated assessments and applying late filing penalties. If you are considering deregistering for VAT, it is important to ensure all outstanding RTDs are submitted before the deregistration takes effect.
The RTD requires you to provide a detailed breakdown of your supplies and purchases across several categories. On the supply side, you must declare total goods and services supplied at each VAT rate, including the standard 23% rate, the reduced rates of 13.5% and 9%, zero-rated supplies, and exempt supplies. Each category must be reported separately to give Revenue a clear picture of your trading activity.
On the purchase side, you declare total goods and services acquired, again broken down by VAT rate. This includes imports from outside the EU and intra-Community acquisitions from other EU member states. You must also report any self-supplies or reverse charge transactions. The figures should reconcile with the records in your financial statements and the VAT amounts declared on your periodic returns throughout the year.
Accuracy is critical when completing the RTD. The figures must match the underlying invoices and accounting records. Revenue uses the RTD as a primary cross-checking tool, comparing the annual totals against the sum of your bi-monthly returns. Material discrepancies can trigger a Revenue intervention, which may escalate into a full compliance audit.
The RTD must be filed within 23 days of the end of your VAT accounting year. For most businesses whose VAT year aligns with the calendar year ending on 31 December, the RTD deadline falls on 23 January of the following year. If you file through the Revenue Online Service, you may benefit from a short extension, but the exact date is confirmed each year by Revenue.
It is worth noting that the RTD deadline is separate from your CT1 return deadline for corporation tax. Many founders confuse the two, but the RTD relates solely to VAT and follows its own submission calendar. Keeping both deadlines clearly marked in your compliance calendar prevents costly overlaps and missed filings.
Your bi-monthly VAT returns (VAT3) capture the VAT charged and reclaimed during each two-month period. The RTD, on the other hand, consolidates all of this data into a single annual summary. Think of the bi-monthly returns as the individual chapters of a book, and the RTD as the table of contents that ties everything together for Revenue.
When Revenue reviews your RTD, they compare the annual totals against the sum of all VAT3 returns filed during the same period. If the numbers do not match, this raises a flag. Common reasons for discrepancies include timing differences on invoices, adjustments for bad debts, or errors in categorising supplies at the correct VAT rate. Resolving these discrepancies proactively with your accountant before filing prevents unnecessary queries from Revenue.
Late filing of the RTD can result in penalties and may affect your VAT compliance record with Revenue. While the specific penalty amounts can vary, Revenue takes a dim view of persistent late filers and may use the failure as a basis for initiating a compliance intervention or audit of your wider tax affairs.
Beyond penalties, a late or missing RTD can also delay the processing of VAT refunds your business may be owed. For companies in a regular refund position, such as exporters who zero-rate their sales whilst reclaiming input VAT, this delay can have a direct impact on working capital and preliminary tax planning.
Effective preparation for the RTD starts with maintaining accurate records throughout the year. Ensure that every sales and purchase invoice is correctly coded with the appropriate VAT rate in your accounting software. Running a monthly or quarterly reconciliation between your VAT returns and your general ledger will catch errors early, long before the annual filing deadline arrives.
Your accountant will typically prepare the RTD by extracting summary data from your accounting system and cross-referencing it against the VAT3 returns already submitted. If your business has complex transactions, such as intra-EU supplies, imports, or mixed exempt and taxable activities, additional care is needed to ensure each category is reported in the correct field. Investing time in this process protects your company from costly Revenue queries and reinforces your overall tax compliance standing.
