Note:

Where returns and payments (corporation tax – preliminary tax, annual CT1 return, balancing payment; VAT – VAT3 Return, VAT due; and RCT – Monthly RCT30 Return, RCT due) are made electronically, the return and payment deadlines are being extended to the 23rd day of the month. A similar extension to the PAYE/PRSI monthly return filing/payment deadline to the 23rd day has also been made.

Where the filing and payment requirements are not made by the extended deadline, interest will run from the normal deadline and not the extension date.
