Around 420,000 people nationwide will be issued tax bills today as a result of payments they received under the two main Covid subsidy schemes last year.
71% of those in receipt of the Temporary Wage Subsidy Scheme and 33% of those on the Pandemic Unemployment Payment underpaid tax and will receive a bill.
Data released by Revenue yesterday shows that 80% of taxpayers' statements are balanced, overpaid or underpaid by less than €200, while 706,000 taxpayers are due a refund.
In total, over 600,000 people underpaid income tax or universal social charge in 2020.
This is partly due to the fact that the TWSS and PUP payments were not taxed at source.
The amount outstanding is €458 million.
Revenue has confirmed that this tax liability will not be due this year.
Although the option is available for taxpayers to fully or partially pay any liability through their online account with Revenue, people are not expected to make a lump sum payment.
