The ACT government's rent reduction scheme will be extended until the end of the year.
It will mean landlords who reduce tenants' rent by at least 25 per cent can continue to receive rebates on land tax of up to $100 a week.
Only tenants who have been impacted by the coronavirus pandemic are eligible for the reduction.
The scheme was implemented in April as part of the government's coronavirus economic response. It was intended to go for six months.
As of August 13, 759 landlords had applied for the rebate. They will have to apply again to extend the rebate.
ACT Attorney-General Gordon Ramsay said he was pleased at the number of landlords who had applied for the scheme.
"We understand this is a difficult time for many Canberrans, particularly those who have suffered a significant reduction in their income," he said.
"However, I want to remind people that this isn't a license for tenants to completely forgo their rental obligations. If you are not impacted by COVID-19 and can pay your rent then you are required to do so."
