The Cabinet has approved the extension of two flood assistance schemes for businesses and community organisations.
Both schemes, which were initially opened following Storm Babet last month, will now run until 5 November.
At an incorporeal Cabinet meeting ministers agreed to extend the time during which businesses, community organisations and sports clubs can apply for funding.
Under the maximum level of funding, those eligible will be able to claim up to €100,000.
The memo was brought forward by Minister for Enterprise Simon Coveney.
Under the first scheme, eligible businesses, community organisations and sports clubs, which could not secure flood insurance, can claim for an initial payment of €5,000 and a further audited payment of up to €20,000.
However, the worst affected businesses and organisations can claim for a quick payment of €10,000 and an audited payment of up to €100,000.
In the aftermath of Storm Babet, the Department identified around 190 flooded businesses.
The first payments for those impacted were administered on Wednesday, with around two-thirds of applications seeking the lower support package limited to €20,000.
A number of business in Midleton, Co Cork, one of the worst-hit towns during Storm Babet, have begun to receive payments under the flood relief schemes.
It is understood five businesses have received the initial emergency payments of €10,000.
So far, 39 businesses in the town have applied for the funding in the aftermath of Storm Babet which caused millions of euros of flood damage in east Cork.
Cork County Council estimates 250 homes and businesses in Midleton were flooded in the wake of a month's rainfall in the space of 24 hours.
According to Midleton and Area Chamber of Commerce, 16 businesses who could not secure flood insurance have applied for relief under the first scheme.
Some 20 other businesses including community organisations and sports clubs have applied under the second scheme.
Three others are waiting for confirmation on what scheme to apply for.
President of the Chamber Adrianna Hegarty welcomed confirmation that businesses have begun to receive the emergency flood payments.
Ms Hegarty said they will be keeping in touch with their members to see how the process of accessing the payments is going for them.
She said that since the flooding, the Chamber has been working with the Red Cross and the Local Enterprise Office to set up a business advice clinic to help people with the process of accessing the funding for their businesses and organisations.
This is due to open next week.
The Chamber has 100 members but since the flooding is in regular contact by text and email with some 170 businesses in the area.
A number of initiatives are planned for the coming weeks to encourage people to shop locally.
Speaking from South Korea before today's Cabinet meeting, the Taoiseach said: "In the next couple of hours there will be an incorporeal meeting.
"... We will use that meeting to extend the flood relief schemes for affected businesses and homes to both Louth and Wexford in response to the flood events.
"Thankfully, while there has been significant damage, it isn't as severe as the damage we have seen in Midleton and Cork in the last couple of weeks but we are extending the same schemes both to households with the revised terms and to businesses as well."
Speaking on RTÉ's Morning Ireland, Minister of State with responsibility for trade promotion, digital and company regulation Dara Calleary said the Government wants to issue payments as quickly as possible to those affected by flooding.
"We are trying to get a system that gets money out quick.
"We're very conscious that coming up to Christmas is a core time of year for businesses.
"We want to get them back up and running as far as they can.
"This is an appalling situation in Carlingford, in Wexford, our thoughts are with those and we want to get supports to them as quick as possible."
