From the erm:
COVID-19 payments
People getting COVID-19 payments – either the COVID-19 Pandemic Unemployment Payment or Revenue’s wage subsidy schemes (including the Temporary Wage Subsidy Scheme, the Employment Wage Subsidy Scheme and the Employer COVID-19 Refund Scheme) – will be awarded PRSI contributions at the class they were paying immediately before they were laid off, while they are getting the relevant payment or scheme.
So no need for volunatry contributions on account of the covid anall.
