8,849 businesses have registered for the Government's energy support scheme since it opened to applications late last year.
Nearly 4,000 of those firms have begun the claims process for the Temporary Business Energy Support Scheme (TBESS) with over two thirds having fully completed it and €6.6m paid out to date.
The scheme is open to certain businesses that have seen their energy bills increase by at least 50% between September of last year and February of this year, when wholesale costs rocketed due to the impact of the war in Ukraine.
Under the €1.2 billion plan, eligible applicants will get up to 40% of the increased value of their energy costs when compared to the same time last year.
Revenue says each business can make more than one claim, depending on the frequency of its energy bills.
So far, the largest number of registrations and claims have come from the wholesale and retail trade, followed by accommodation and food, with 2,271 retailers registered alongside 1,273 cafés and restaurants and 905 bars.
Nearly a quarter of registered claimants are in the Dublin area, followed by Cork and Galway.
The figures were published by the tax collection authority as issued a range of headline statistics covering 2022.
In total it collected €82.2 billion in tax and duty on behalf of the exchequer, up €14.7 billion or 21.5% on the previous year.
€22.3 billion was also collected on behalf of other departments, agencies and EU member states.
"These unprecedented Exchequer receipts are underpinned by continued high levels of voluntary timely compliance, notwithstanding the challenging circumstances in which many taxpayers found themselves," said Niall Cody, Revenue chairman.
Over 427,000 audit and compliance interventions were carried out through the course of the year which yielded €813m.
"We also secured nine criminal convictions for serious tax evasion and fraud, published 53 tax settlements in the List of Tax Defaulters and settled 104 tax avoidance cases yielding €16.1m," Mr Cody said.
"The identification, targeting and disruption of shadow economy and other illegal activity continues to be a key focus for Revenue," he added.
"In 2022, we seized over 51 million cigarettes valued at €39.4m and over 3,600 kilos of drugs with an estimated value of €46.4m," Mr Cody said.
Last year also saw the Covid-19 subsidy schemes come to an end, with a total of over €10.2 billion paid out under the two wage subsidy schemes and the Covid Restrictions Support Scheme.
Revenue also said that 72,000 businesses continue to avail of the tax warehousing scheme, with €2.48 billion worth of debt still included.
Throughout the year Revenue also processed 40.2 million customs declarations, an increase of 58% on the previous year, with Brexit playing a major role in the increase.
In total €640m in customs duty was collected, up €110m or 21% on the previous year.
"Of the €0.64 billion customs duty collected, €0.28 billion is in respect of imports from the UK indicating that businesses by and large have successfully adapted to the customs formalities that govern the trading relationship with the UK," Revenue Commissioner and Director-General of customs Gerry Harrahill said.
Revenue also resumed general debt enforcement during the year, after a suspension during the pandemic.
"We do, of course, understand that businesses can have temporary cash-flow difficulties," said Mr Cody.
"In those circumstances, the important thing is to file the required tax returns and engage with us early," he urged.
