How to File a VAT3 Return — 7 Steps
Complete walkthrough of the VAT3 return on ROS, from login to payment.
Log in to ROS
Access Revenue Online Service (ROS) at www.ros.ie. You need a digital certificate (ROS cert) installed on your browser. If first time, register at MyAccount first, then request ROS access.
Select VAT3 Return
Navigate to 'File a Return' → select 'VAT3' from the return type dropdown. Choose the correct taxable period (bi-monthly: Jan–Feb, Mar–Apr, May–Jun, Jul–Aug, Sep–Oct, Nov–Dec).
Complete Box T1 — VAT on Sales
Enter total VAT charged on sales/supplies at each rate. ROS auto-calculates from individual rate boxes (T1a–T1e). Include VAT on self-supplies and intra-EU acquisitions.
Complete Box T2 — VAT on Purchases
Enter total deductible VAT on purchases. This is your input VAT credit. Only include VAT on goods/services used for taxable purposes. Partially exempt? Apply the Two-Thirds Rule or actual apportionment.
Review Boxes E1 & E2
E1 = Total value of goods/services supplied (ex-VAT). E2 = Total value of intra-EU acquisitions. These are informational but Revenue uses them for cross-checks.
Calculate Net VAT (T1 – T2)
If T1 > T2, you owe Revenue the difference. If T2 > T1, you can claim a refund. Revenue typically processes VAT refunds within 5 working days if filed electronically.
Submit & Pay via ROS
Click 'Sign & Submit' using your ROS certificate. If VAT is due, pay via ROS debit instruction (RDI) — direct debit from your bank. Payment must reach Revenue by the 23rd of the month following the period.

Common VAT Filing Mistakes
Avoid these errors that trigger Revenue audits and penalties.
Wrong VAT rate applied
Check Revenue's VAT rate database — rates change. Hospitality went 9% → 13.5% → 9% → 13.5% in recent years.
Missing intra-EU VAT (reverse charge)
B2B services from EU suppliers must be self-accounted via reverse charge. Include in both T1 (output) and T2 (input).
Not filing RTD
Annual Return of Trading Details must be filed even if all VAT3 returns are submitted. Due by 23rd of the month after year-end.
Late filing penalties
Interest at 0.0274% per day on late payments. Surcharge of €50–€500 for late filing. File via ROS for automatic 23-day extension.
Claiming VAT on exempt items
No input VAT recovery on entertainment, motor vehicles (some exceptions for taxis/driving schools), or exempt supplies.
