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 extended to the 23rd day of the month. A similar extension to the 23rd day applies for the PAYE/PRSI monthly return filing/payment deadline.

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.
