The two-tier system comes into effect from tomorrow.
110 thousand people will receive the lower rate of the Covid-19 pandemic unemployment payment this week.
The two-tier system comes into effect tomorrow, with those who earned less than 200 a week before the pandemic, to be moved to a 203 euro weekly rate.
The remaining 300 thousand recipients will remain on the 350 euro rate.
The Department of Social Protection says 63 thousand people have closed their claim in the last week.
