Sixteen Days to 14 September: Ireland August PAYE Return
As of 29 August 2026, Irish employers have sixteen days to the 14 September PAYE/PRSI/USC/LPT return for August — with ROS payment extended to 23 September where you file and pay online.
Revenue’s Calendar of key dates for tax professionals lists 14 September 2026 for the monthly PAYE/PRSI/USC/LPT return and payment for August 2026, with the payment date extended to 23 September for ROS users who file and pay online. As of Saturday 29 August — with July IOSS two days out on Monday 31 August — employers have sixteen calendar days to the August return date.
The same 14 September date also carries Dividend Withholding Tax and Professional Services Withholding Tax monthly returns for August. Treat payroll, DWT, and PSWT as one mid-September ROS session if your profile carries more than one obligation.
Who must diary 14 September
Employers filing the August 2026 PAYE/PRSI/USC/LPT monthly return — paper or non-ROS payment paths do not receive the 23 September payment extension.
Companies remitting August DWT or filing F30 PSWT for August on the same date.
Payroll agents sequencing August payroll close after the July ROS cash work so September does not start with open July journals.
Sixteen-day payroll checklist
Clear July IOSS this weekend if it sits on your profile, then lock August payroll runs and employee changes before mid-September leave thins coverage.
Confirm ROS payment mandates and dual approvals for the 23 September ROS payment path if you use the extension.
Diary bi-monthly VAT (19 September) and December year-end CT1 (23 September) beside PAYE so September ROS days stay sequenced.
Keep RCT August returns (23 September) on the same late-September cash calendar if you are a principal contractor.
