The additional income of Monaghan's Local Property Tax will go towards the "economic development of the county".
Yesterday, the local authority voted in favour of increasing the tax by 15 per cent.
The Local Property Tax resets each year, with every county council given the option to adjust it by plus or minus 15 per cent.
Councillors voted to increase the rate by the maximum percentage, meaning the amount paid by a household will be the same as last year, when a 15 per cent rise was also adopted.
Funds from the tax are put into a discretionary allocation, which each Municipal District can use to match funding for community and enterprise projects.
Rossmore Park as well as the C:Tek building and Workhouse in Carrickmacross were some of the developments mentioned as having benefited from having these funds available.
Fianna Fáil Councillor PJ O'Hanlon proposed the motion and said while it wasn't popular; it's for the benefit of the county:
Fianna Fáil, Fine Gael and Independent members voted in favour of the increase, with Sinn Féin voting against - after Cathaoirleach of the council Colm Carthy had his motion to leave the LPT unchanged defeated.
