Ireland reporting cycles and business-day rules
Irish business-day cycles align with Revenue's VAT3 bimonthly cutoffs (paper on the 19th, ROS extended to the 23rd) and PAYE monthly remittance on the 14th of the following month for most employers, with the PAYE Modernisation system reporting in real time on each pay event. The Central Bank of Ireland operates TARGET2-IE for euro wholesale settlement on TARGET2 business days, which exclude bank holidays. Form CT1 corporation tax is due nine months after the company year-end. The European Communities (Late Payment in Commercial Transactions) Regulations 2012 set 8% above the ECB main refinancing rate as the statutory late-payment interest rate, payable from day 31 after invoice for B2B transactions.
