The coalition parties are going it alone in the local and European elections and running their own entirely separate campaigns.
From the start of next year, local authorities will be allowed to vary the property tax rates by 15pc of the national central rate.
Tanaiste Eamon Gilmore confirmed his party will campaign to reduce the property tax burden, as revealed in yesterday's 'Sunday Independent'.
"The Labour Party supports that and we will be making that clear to people," he said.
"The Labour Party will pursue this policy," he added.
Labour is seeking a catchy policy to shore up its support at council level.
The move on property tax is likely to play well in particular in Dublin, which has been described as representing "Labour's Stalingrad" in this year's local elections.
Mr Gilmore indicated yesterday that the ability to adjust property tax would impact on householders in larger, urban areas where property values are higher and therefore homeowners are paying a higher amount of property tax.
But the measure is also likely to intensify tensions within the Coalition, particularly amongst the more rural wing of Fine Gael.
Not every council is going to be able to afford to reduce the property tax, but councils with large populations will have more funding.
