Dublin's City Manager wants the Government to close a loophole which means owners of newly built homes are exempt from property tax.
It is claimed the city council is losing out on €15m as a result
Homeowners pay property tax based on an evaluation recorded in 2013.
People who have bought new builds since then don't have to pay the levy because the property did not exist at the time of the valuation.
They are not due to be hit with a bill until October 2019 but the city manager wants the government to change that.
In a report on next year's council budget seen by the Irish Times, City Manager Owen Keegan said this inequality and loss of revenue needs to be addressed.
The local authority uses the property tax to fund public services, but it is estimated this loophole see it losing out on €15m in 2018.
