There are now 464,400 employees having their wages subsidised by the Government under the Temporary Wage Subsidy Scheme.
The policy has come at a cost of €936m so far, according to the latest figures published by the Revenue Commissioners.
There are 53,900 employers registered for the TWSS, of whom 47,300 have already received subsidy payments under the scheme.
The €936m spent on the scheme, up to today, includes €86m in income tax refunds.
The 12-week TWSS is intended to encourage employers to maintain the employment link between companies and their employees, to facilitate a more rapid return to activity as the economy gradually reopens.
The latest Revenue figures, which exclude the public sector and workers receiving occupation pensions, clearly indicate the dramatic extent to which both workers' incomes and tax revenue have dropped since the Covid-19 crisis began.
In January, 1.9m workers received total gross pay of €6.186bn, averaging €3,249 per worker per month.
However, based on preliminary data for April reflecting substantial job losses, 1.6m workers (300,000 fewer) earned gross pay of €4.715bn, with average monthly pay falling to €2,942.
The State has also lost out significantly on tax.
The total income tax take in January from workers was €1.077m, but by last month, that had fallen €836m.
The €211m in USC paid in January fell to €168m last month, with Employee PRSI decreasing from €220m to €165m over the same period.
The State revenue from Employer PRSI reduced from €595m to €421m.
However, the figures are even more stark for employees covered by the TWSS, who must earn less than €76,000 a year to be eligible.
In January, 450,000 TWSS workers earned total gross pay of €1.260bn, averaging €2,819 per month.
By April, that had collapsed to total gross pay of €462m, or a monthly average of €1,030.
The income tax take from such workers plummeted from €157m in January, to a shortfall of €31m.
TWSS workers paid USC totalling €32m in January, but in April the State took in just €1m in respect of them.
Employee PRSI contributions totalling €45m in January plummeted to just €7m in April, with Employer PRSI contributions dropping from €123m in January to €19m over the same period.
Of workers receiving the Government earnings subsidy, 24% are in the wholesale and retail trade, 14.3% are in manufacturing, 10.3% in construction and 10% in accommodation and food services.
Between them, Dublin city and county accounted for 43.4% of employees and 32.7% of employers covered by the TWSS.
Only 14% of workers in the TWSS are earning above €586 per week.
The 12-week scheme is due to expire in late June, but the Government has already indicated that both the TWSS and the Covid-19 Pandemic Unemployment Payment are likely to be extended, although it is unclear for how long and in what form.
