Thousands of people will receive a share of €2 million in PUP arrears payments this week.
The Department of Social Protection confirmed that the arrears are owed to around 6,500 people who are no longer in receipt of PUP and "who may not be expecting a payment this week".
A spokesman said: "The payments will be paid directly through the Post Office or into the nominated Bank accounts of these individuals tomorrow, 9th March.
"The quickest way for a person wishing to check the details of their arrears payments is via www.MyWelfare.ie.
"The vast majority of arrears cases (more than 280,000) were paid last December and some 38,600 received an arrears payment on 23rd February."
Meanwhile, the number of people receiving the Pandemic Unemployment Payment has fallen slightly, down almost 4,000 on last week.
Minister for Social Protection Heather Humphreys praised the national effort to reduce the number of coronavirus infections - and issued an important reminder for anyone in need of financial support.
She said: “This week again we see a small but steady number of people closing their claim for the Pandemic Unemployment Payment.
“I want to commend the huge efforts being made by people, young and old, which are paying dividends in helping to suppress the Covid-19 virus.
“This virus has remained with us far longer than any of us anticipated. I know people are feeling weary and anxious and just want life to get back to normal.
"But our efforts are making a difference. We are seeing positive signs in terms of hospital numbers and ICU numbers, which are reducing all the time.
“We cannot let our guard down at this time. Employees need to work from home where possible. All of us need to continue to follow the health guidelines and remind ourselves that we are making these sacrifices on behalf of our families, our friends, our communities and our frontline workers.”
Minister Humphreys added: "I want to remind people that my Department provides a range of means assessed financial supports for individuals and families, depending on their particular circumstances.
“Full details of these supports can be viewed on the Department’s website www.gov.ie/dsp or by contacting its Income Support Helpline at 1890 800 024 between 9am and 5pm Monday to Friday.”
