Galway County Councillors have voted to approve a 15% increase local property tax rates.
The local authority said the move will bring in an additional €2.4 million per year to fund services around the county.
Members voted by 32 to 6 in favour of the increase at today's Council meeting, with one representative absent.
The hike will apply to local property tax rates from 2025.
Council Chief Executive Liam Conneally said the additional income derived from the move will secure "badly needed funding" to deliver a range of projects in the coming years.
Each local authority in the country can increase or decrease the rate by up to 15% from the basic property tax rate each year.
Galway County Council was one of only a handful of local authorities that did not alter the rate for 2024 payments.
It said this increase will add an extra €13.50 per year to the charges faced by over 40% of property owners around the county.
Almost 50% of homeowners will see their local property tax increase by between €33.75 and €47.25, while the charge will go up by €65.50 for the remainder of those impacted.
