Irish VAT Returns 2026
VAT returns abroad require a reconciled ledger, VAT3 form, EU reports, and customs data. In Ireland, the basic return is usually bimonthly, and the result must be settled via the Revenue Online Service.
In this guide, you will review deadlines, T1–PA1 fields, nil declaration, RTD, VIES, Intrastat, payments and how to correct errors after obtaining an IE number.
VAT Returns in Ireland: A Roadmap to Obligations
VAT3 calculates tax for the period. Other reports show the same turnover from a different perspective, so the amounts must be reconciled.
Periodic declaration
T1 and T2 show the tax due and deducted, and T3 or T4 the result to be paid or refunded.
Annual settlement
Sales and purchases are compiled according to Irish VAT rates and transaction type.
VIES and Intrastat
VIES reports eligible deliveries and Intrastat reports the physical flow of goods after exceeding the threshold.
Submission and payment
Declaration, payment and confirmation are handled by the Revenue Online Service.
From Taxenlight experience
We most often rectify settlements where VAT3 is arithmetically correct but does not match VIES, the import report, or the general ledger. Period-end closing should include all reports, not just the T3 result.
Who files VAT3 in Ireland?
VAT3 is filed by a taxpayer with an active Irish VAT registration – even a foreign company without an office or employees in Ireland.
The obligation lasts from the effective date of registration until formal deletion. Imports in one's own name, stock in an Irish warehouse, or local sales can therefore trigger periodic reporting even if the company maintains its accounts in another country.
If you're just assessing the need for an IE number, check out our VAT Registration in Ireland. This assumes you've already been issued a number and outlines your billing obligations.
Active number means active duty
- submit VAT3 for each assigned period;
- don't skip the sales free period;
- check RTD, VIES and Intrastat separately;
- keep proof of shipment and payment.
How often is VAT3 filed?
The standard period is two months. Any other frequency requires assignment or consent from Revenue; it cannot be selected independently in accounting.
Standard
January–February, March–April, May–June, July–August, September–October and November–December.
Regular return
Revenue may approve a monthly period for a taxpayer who remains in a permanent refund position.
Lower VAT amount
Possible with an annual commitment of €3,001 to €14,400.
The smallest obligation
Possible when the annual VAT amount does not exceed EUR 3,000.
Check the period visible in ROS
Revenue also publishes deadlines for individually assigned annual cycles. However, don't assume this frequency based on turnover—the period assigned to the taxpayer's account applies.
VAT3 and payment deadlines in Ireland
The statutory deadline is the 19th day of the month following the end of the period. For taxpayers filing their returns through the ROS, the deadline is extended to the 23rd day.
| VAT period3 | Statutory deadline | Deadline by ROS | What to close early |
|---|---|---|---|
| January–February 2026 | March 19, 2026 | March 23, 2026 | sales, purchases, imports and EU transactions |
| March–April 2026 | May 19, 2026 | May 23, 2026 | VAT3, payment and related reports |
| May–June 2026 | July 19, 2026 | July 23, 2026 | differences between the book, VIES and AIS |
| July–August 2026 | September 19, 2026 | September 23, 2026 | credit notes and Intrastat data |
| September–October 2026 | November 19, 2026 | November 23, 2026 | fields T1–PA1 and payment |
| November–December 2026 | January 19, 2027 | January 23, 2027 | VAT3, RTD and year-end closing |
Set an earlier internal appointment
Don't wait until day 23 to submit your data. Close the period a few days in advance and check Revenue's current calendar of deadlines, especially if the day falls on a weekend or holiday.
How to prepare and submit VAT3 step by step?
Start with the source books and documents. The ROS form is the final step, not the place to create a settlement.
Select period
Check the frequency and correct VAT period shown in the taxpayer's account.
Close the books
Reconcile sales, purchases, credit notes and import documents.
Calculate T1 and T2
Add sales, reverse charge, EU acquisitions and postponed accounting.
Set the score
Calculate the T3 for payment or T4 for refund and check the right to deduction.
Complete the EU fields
Enter E1, E2, ES1, ES2 and the import value in PA1.
Reconcile reports
Compare VIES, Intrastat, AIS, Postponed VAT Report and OSS records.
Send via ROS
Verify the summary, submit the form and keep the confirmation.
Make a payment
Assign the amount to VAT and the correct period, then check the accounting.
How to fill in fields T1–PA1 in VAT3?
T1 and T2 contain tax amounts. E1, E2, ES1, ES2, and PA1 show transaction values excluding VAT or the import basis.
| Field | Type of value | What to demonstrate | What to agree with |
|---|---|---|---|
| T1 | VAT amount | VAT on sales, EU acquisitions, services received and imports in postponed accounting | sales ledger, reverse charge, AIS and import calculation |
| T2 | VAT amount | VAT deductible on purchases and transactions settled by the buyer | purchase book, right of deduction and source documents |
| T3 | VAT amount | difference to be paid when T1 is greater than T2 | payment order and VAT account in ROS |
| T4 | VAT amount | difference to be refunded when T2 is greater than T1 | Refund account, arrears and deduction documentation |
| E1 | net worth | goods shipped from Ireland to customers in other EU countries | VIES, invoices and Intrastat dispatches |
| E2 | net worth | goods received from suppliers from other EU countries | acquisitions in T1/T2 and Intrastat arrivals |
| ES1 | net worth | qualified B2B services for taxpayers in other EU countries | VIES service part and sales invoices |
| ES2 | net worth | services received from EU suppliers billed by the Irish buyer | reverse charge in T1/T2 and purchase book |
| PA1 | customs value + duty | imports reported using postponed accounting, also with a 0% rate | AIS, Customs Declarations and Postponed VAT Report |
Taxenlight advises: don't treat T1 as just a sale
T1 also includes EU acquisitions, services received, and deferred import VAT. The transaction neutrality of full deduction doesn't mean it can be ignored—the amount is often filed concurrently in T1 and T2.
Example of completing VAT3
The company sells locally, buys goods from the EU, imports with postponed accounting and receives foreign services.
VAT due
- local sales: €23,000;
- purchase of goods from the EU: EUR 4,600;
- import in postponed accounting: EUR 11,500;
- services received: €2,300.
T1 = 41,400 EUR
Deductible VAT
- domestic purchases: €16,100;
- purchase of goods from the EU: EUR 4,600;
- import: 11,500 EUR;
- services received: €2,300.
T2 = 34,500 EUR
Declaration result
T1 €41,400 minus T2 €34,500 gives VAT payable. T3 is €6,900 and T4 is €0.
6,900 EUR
Neutral does not mean invisible
Acquisitions, imports and services are neutral with full right of deduction, but must be reported on both sides and in the appropriate information fields.
Zero VAT declaration3
The lack of sales does not suspend the obligation. As long as registration is active, the taxpayer submits VAT3 for each assigned period.
T1, T2, T3 and T4
Enter a zero in each result field. Revenue specifically advises against entering the word "nil.".
Check hidden transactions
Please verify overseas services, EU acquisitions, imports, credit notes and costs against Irish VAT before submitting a zero.
Keep a track of your control
A short period-end closing checklist confirms that the zero is due to verification and not to missing data.
VAT3 does not have a regular invoice-by-invoice attachment
The form is comprehensive, but full records, invoices, notes, statements, and customs documents must generally be retained for six years and made available to Revenue upon request. Check the required VAT documentation.
Return of Trading Details - RTD
RTD is an annual statement of sales and purchases at VAT rates. It does not replace VAT3 and does not result in repayment of tax.
What does RTD cover?
- net sales at rates;
- exempt sales and 0%;
- shopping at rates;
- EU transactions and imports;
- values postponed accounting;
- corrections included in the annual settlement.
When to submit?
RTD appears in the ROS box with the final VAT3 for the accounting year. For electronic settlements, the deadline is the 23rd day of the month following the taxpayer's year end.
Failure to obtain an RTD may result in a fixed penalty of €4,000.
How to reconcile RTD?
Compare your statement with your full-year VAT3 total, general ledger, E1–ES2, PA1, AIS reports, credit notes, and sales and purchases by rate. Explain the difference before submitting, rather than manually adjusting the RTD.
VIES and Intrastat in Ireland
VIES tracks eligible deliveries to taxpayers in other EU countries. Intrastat describes the physical movement of goods after they cross the threshold.
Delivery of goods and services
- no minimum threshold for a qualifying transaction;
- monthly after exceeding EUR 50,000 of goods delivered in a quarter;
- in other cases, a quarterly cycle is possible;
- due date: 23rd day following the month or quarter.
Reconcile E1 with goods in VIES and ES1 with reported services.
Threshold €750,000
- 750,000 EUR for arrivals;
- EUR 750,000 separately for dispatches;
- the detailed declaration is monthly;
- the report covers goods, not services.
The thresholds apply from 1 January 2025 and remain valid in 2026.
One delivery, several inspections
Intra-Community deliveries of goods can be processed in parallel with E1, VIES, and Intrastat dispatches. The customer number, value, period, and transport documents must form a single, coherent track.
Import, reverse charge, OSS and IOSS in reporting
This section shows where transactions appear in your reports. Taxation conditions and rates are described in a separate guide, VAT in Ireland.
Postponed accounting
Import VAT goes to T1 and, within the limits of the right of deduction, also to T2. PA1 shows the customs value increased by customs duty, also for imports with a 0% rate.
Reverse charge
Services received and EU acquisitions increase T1. If there is a right to deduct, the corresponding amount also goes to T2; the bases may go to E2 or ES2.
Union OSS
Settlement is quarterly and separate from VAT3. Sales covered by the procedure are not automatically transferred to the national declaration.
IOSS
The declaration is monthly and submitted by the end of the following month. Also check the zero reporting requirement for periods without sales.
Taxenlight advises: separate procedures from local sales
OSS does not cover the ordinary sale of your own goods from an Irish warehouse to an Irish consumer. Such sales remain in your domestic VAT return.3 The OSS VAT declaration service can help you manage your e-commerce .
VAT payment and T4 return
The T3 amount is payable on the same date as the VAT3. Submitting the form alone does not constitute payment.
Before payment is approved
- check tax number and tax type;
- select the correct VAT period;
- compare the amount with T3;
- verify your account and bank limit;
- check the date of execution of the order;
- keep confirmation from ROS.
When T4 is created
The Revenue Service may transfer the refund to a VAT account, offset it against other arrears, or initiate an audit. Before submitting, check your bank details and the completeness of your deduction documents.
How to correct VAT3 and related reports?
Don't automatically transfer the difference to the current period. First, determine the correct period and all forms affected by the error.
Determine the source of the error
Check the invoice, note, accounting, exchange rate, customs document and the moment of obligation.
Determine affected fields
Verify T1–T4, E1–ES2, PA1 and the result of the payment or refund.
Check out the other reports
The same correction may require a change to VIES, Intrastat, RTD, OSS or IOSS.
Correct the correct period
Prepare a complete correct assembly and use the current function available in ROS.
Pay tax and interest
If the correction increases T3, settle the arrears as soon as possible and assess the need for disclosure.
From our experience
The riskiest are "silent" accounting corrections that correct VAT3 but leave the old values in the VIES or import report. Prepare a short correction note listing all changed reports and documents.
VAT declaration compliance matrix
Each field should link to a source document and report that shows the same transaction.
VAT3 and books
- T1 with sales book, reverse charge and import;
- T2 with purchase book and right of deduction;
- T3 or T4 with calculation and VAT account balance;
- credit notes with the appropriate period.
Additional reports
- E1 with VIES and Intrastat dispatches;
- E2 with EU acquisitions and Intrastat arrivals;
- ES1 with services reported in VIES;
- PA1 with AIS and Postponed VAT Report;
- RTD with full year total.
Taxenlight advises: close the period using a transaction matrix
For each type of sale or purchase, assign VAT3 fields, an additional report, proof of purchase, and data owner. Clarify any differences before submitting, rather than manually recording them for compliance.
↔ data
The most common errors, interest and penalties
The Revenue may charge interest, issue a VAT assessment, or impose a penalty. Filing a late return does not automatically eliminate the consequences of the late payment.
Errors in VAT3
- T1 limited to sales only;
- full T2 despite limited deduction;
- VAT instead of base in PA1;
- omitting PA1 for import 0%;
- no zero declaration.
Reporting discrepancies
- E1 not VIES compliant;
- E2 non-compliant with Intrastat arrivals;
- invalid customer number;
- RTD without annual reconciliation;
- local sales included in OSS only.
Financial consequences
Interest on VAT arrears is 0.0274% for each day or part of a day. The fixed penalty for failing to submit VAT3, RTD, or the required VIES can be €4,000.
For arrears of €20,000 over 60 days, the interest is €328.80.
VAT estimate does not replace the declaration
Where VAT3 has not been filed, Revenue can estimate the liability. The taxpayer must still submit the correct return and pay the actual tax. Check the official Revenue VAT estimate rules and interest rates .
Irish VAT Returns 2026 – Key Takeaways

Keep an eye on your period and deadline
The standard is two months and the 19th day, extended for ROS to the 23rd day.
Understand VAT3 fields
T1 and T2 are VAT amounts, and E1–ES2 and PA1 describe the basis and values of the transaction.
Align the entire ecosystem
Check VIES, Intrastat, AIS, RTD, OSS or IOSS, payment and documentation.
Irish VAT Returns - Questions and Answers
Short answers about VAT3, deadlines, declaration fields and additional reports.
VAT3 is the basic Irish VAT return. It shows VAT payable, VAT deductible, payable or refundable, and the value of EU transactions and imports subject to postponed accounting.
Standard payment period is every two months. Revenue can approve a monthly, four-month, or six-month period. The frequency assigned to the taxpayer's account applies.
The statutory deadline is the 19th day of the month following the period. For returns filed through the ROS, the deadline is extended to the 23rd day.
Yes. As long as the registration remains active, the absence of a transaction does not exempt you from the obligation to declare. In T1, T2, T3, and T4, enter 0, not the word "nil.".
T1 includes VAT due on sales, EU acquisitions, services received, and imports accounted for through postponed accounting. T2 includes VAT that the taxpayer is entitled to deduct.
PA1 shows the customs value of imports subject to postponed accounting plus duty. It does not include import VAT or the value of subsequent sales.
The Return of Trading Details (RTD) is an annual statement of sales and purchases at VAT rates. The RTD is filed at the taxpayer's year-end and does not replace VAT3.
VIES is submitted for the assigned monthly or quarterly period by the 23rd of the following month. For eligible deliveries, there is no minimum value per transaction.
EUR 750,000 per year for arrivals and a separate EUR 750,000 for dispatches. Intrastat concerns the physical flow of goods, not services.
VAT3 is a consolidated declaration and does not have a regular invoice-by-invoice attachment. However, the taxpayer must maintain full records and make documents available to the Revenue upon request.
Determine the correct period and all reports affected by the error, prepare the correct data set, and use the current adjustment function in ROS. If the adjustment increases tax, pay the arrears and interest.
Payments are processed electronically via ROS and assigned to the appropriate tax and period. Before the due date, please verify your account, limit, and actual payment date.
This text is for informational purposes only and does not replace individual tax analysis. When filing VAT returns in Ireland, it's important to verify taxpayer status, accounting period, transaction type, applicable forms, the Revenue system, and current reporting obligations.
