New figures from the Department of Finance show significant uptake of the Covid Restrictions Support Scheme (CRSS) since its launch earlier this month.
6,100 businesses have registered 6,400 premises for the CRSS, while a further 1,800 applications are currently being processed by Revenue, the Department said.
A business that is impacted by Covid-19 related restrictions - including closure - can make a claim for CRSS to Revenue for a payment for each week that it is affected by the restrictions.
The payment is subject to a maximum of €5,000.
Meanwhile, 35,400 employers received Employment Wage Subsidy Scheme (EWSS) payments for October in respect of 345,400 employees.
The Finance figures show that a total subsidy of €358m was paid for the month.
The Department said these figures take account of the impact of the first weeks of the Level 5 restrictions and also reflect the impact of the changes to the EWSS rates which took effect from 20 October and which will remain in place until the end of January.
Finance Minister Paschal Donohoe said the EWSS is a key element of the Government's response to the Covid-19 pandemic by supporting viable firms and preserving the link with employees.
"It is an important bridge between Social Welfare payments like the PUP and the supporting employment which is the core objective of the Government's response," he added.
Mr Donohoe said the current uptake of both the EWSS and the CRSS demonstrates the enduring strengths of the Irish labour market, notwithstanding the disruption caused by Covid-19.
"In particular, although the numbers in receipt of the PUP have increased since the start of October, the impact of Level 5 restrictions on the amount of new claimants has been lower than was projected," he added.
The Minister also said that Revenue is continuing to process applications for the CRSS for businesses significantly impacted by public health restrictions.
It is expected that payments under the scheme will be made by the end of next week. These will be backdated to October 13 for businesses who met the conditions of the scheme at that time, he added.
