Around 82,000 people have claimed for remote working expenses for 2020 so far this year, and Revenue is encouraging more taxpayers to do the same.
Revenue said submitting a claim for these expenses is easier than people might think.
Pat Murphy, Head of Revenue's National PAYE Service, outlined the steps.
"When you go through MyAccount, there is a calculator there and you just input the amount of the bills and the number of days you have been remote working, and it will automatically do the calculation for you," he said.
You do not have to submit a receipt for each bill for electricity or broadband when claiming remote working expenses but there is a 'Receipts Tracker' in MyAccount which allows you to take a picture of the bill on your mobile phone and upload it there and then.
If you do not use this facility, then you must hold onto the bills should Revenue request to check them.
Mr Murphy said the person who is paying the bill should make the claim, but, he added that, "There are situations where children are working from home and contributing to the bill, and if they can demonstrate that, that can be accepted too".
Revenue has also received claims from 212,000 taxpayers for medical expenses in the 2020 returns to date.
Many people returned to education during the pandemic and might not be aware that they are entitled to a rebate from Revenue for a percentage of their tuition fees. All claims can be made via MyAccount on Revenue's website.
Revenue has seen an increase in engagement in recent years from PAYE taxpayers.
"In general, since the introduction of PAYE modernisation in 2019, we've seen a general increase because employees are more aware of their tax credits," Mr Murphy said.
Revenue has also seen an increase in engagement from PAYE taxpayers in 2020 and 2021, who have a tax liability having been put on the Temporary Wage Subsidy Scheme.
Many employers are paying the liability on behalf of their employees, but Revenue does not know how many employers are covering the payment.
"There are two options for employers to pay the tax liability for employees. They can give the money directly to the employee who can then pay Revenue when they're filing their tax return or they can submit it by amending their general payroll submission for 2020, so it's not possible for us to give a definite figure."
Employees can use their tax credits, which may be adjusted over a four-year period, beginning in January 2022, to cover the tax liability on the TWSS.
