Taxi drivers will be able to add 20% to the calculated meter fare on Friday, the National Transport Authority has said.
The increase is due to the bank holiday and will be in place from 8am to 8pm.
Taxis can legally charge a "premium rate" during public holidays but taximeters haven't been reprogrammed for the Bank Holiday on Friday "due to the once off nature".
The National Transport Authority said: "As announced by the Government in January 2022, the Friday after St Patrick’s Day (March 18th) is a once off public holiday.
"Due to the once off nature, it isn’t feasible for taximeters to be reprogrammed to calculate the premium rate legally applicable to public holidays.
"Please note that from 8am to 8pm only on Friday the 18th of March, your taxi driver is entitled to add 20% to the fare calculated by the taximeter in the vehicle. The driver will write the additional 20% on your receipt.
"To estimate the cost of any journey on this day use the Taxi Fare Estimator and select the Premium Rate on transportforireland.ie
"Taxi services are part of the Transport for Ireland network."
