Ireland August deadlines

August Bank Holiday on the first Monday closes banks and Euronext Dublin. Form CT1 for November year-end companies is due August 23. VAT3 for July monthly filers is due August 19 or August 23 via ROS. Many firms run a thin August roster. The ECB rate decision cycle skips August by design, which thins TARGET2 trading and SEPA Credit Transfer batch sizes through the month.

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.

Frequently Asked Questions

How many business days are in August 2024 for Irish public?
August 2024 has 21 working days under the Irish public holiday calendar. The month spans 31 calendar days, of which 9 fall on a weekend and 1 is a Irish public holiday that lands on a weekday. The remaining 21 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which Ireland holidays affect August 2024?
August 2024 contains one Irish public holiday: August Bank Holiday on Monday, August 5. Banks and Ireland financial markets close on each of these days. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
Why is St Brigid's Day included from 2023 onward?
The Sick Leave Act 2022 added St Brigid's Day (Lá Fhéile Bríde) as Ireland's tenth public holiday under the Organisation of Working Time Act 1997. From 2023 the day is the first Monday in February, except when February 1 itself falls on a Friday, in which case February 1 is the public holiday. The holiday recognises both St Brigid and the start of the Celtic festival of Imbolc, and was the first new Irish public holiday added since 1973.
How do observed-day shifts work for Irish public holidays?
When New Year's Day, St Patrick's Day, Christmas Day, or St Stephen's Day falls on a weekend, the observance shifts to the next working day under the Organisation of Working Time Act 1997. Employers grant either a paid day off, an extra day of annual leave, an extra day of pay, or pay for the day as normal. Easter Monday and the four bank holidays on the first or last Mondays (May, June, August, October) always fall on a Monday by definition and therefore have no observance shift.
Why does the business-day count vary year to year?
Two things shift the monthly count for Ireland. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Irish public holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. August 2023 had 23 working days, so August 2024 has 2 fewer working days year over year.
