Dublin City Councillors have voted to halve the refund for vacant commercial properties as part of the 2022 Budget.
The rate was reduced from 30% to 15% to raise €2.25m in increased spending.
However the councillors voted to keep the overall commercial rate the same for next year at 0.268 of the Gross Annual Rental Valuation (GARV).
The council's Head of Finance Kathy Quinn had told councillors "it's a very difficult trading environment. It's not the time to increase costs".
However the 30% rebate given to owners of vacant commercial properties was reduced to 15% after amendments tabled by Labour, the Greens and Fianna Fáil.
The reduction is expected to raise €2.25m which will be spent on reintroducing a free bulky waste collection, new local area plans, new litter bins, two public realm projects and a grant to the city's Beta project for innovation.
Total commercial rate income is projected to raise just under €367m with the council's total expenditure expected to be €1.1bn.
The Government gave just over €100m last year for a rates waiver scheme for businesses affected by the Covid-19 lockdown.
The annual budget meeting heard that there will not be any cuts to services next year.
