Revenue said it collected €87.2 billion in taxes and duties for the Exchequer during 2023 - a record level of tax receipts.
Publishing its headline figures for 2023, Revenue said it also collected over €26 billion on behalf of other departments, agencies and EU member states.
It said last year's record receipts for 2023 were underpinned by high timely compliance rates across all taxes.
"This reflects very positive engagement by businesses, individual taxpayers and agents with their tax compliance obligations. We acknowledge and thank all of them for their co-operation, which reflects the importance that society generally places on a strong culture of voluntary and timely tax compliance," Revenue Chairman Niall Cody said.
"Revenue supports this culture by providing a wide range of services to make it as easy as possible for taxpayers to pay the right amount of tax at the right time, while also confronting and tackling non-compliance in all its forms," Mr Cody said.
"Our approach underpins effective and fair administration of tax and customs law, minimises costs for compliant taxpayers, ensures a level playing field for all businesses, facilitates legitimate trade, and protects society through effective frontier control," he added.
During the year, Revenue secured 21 criminal convictions for serious tax evasion and fraud, published 63 tax settlements in the List of Tax Defaulters and settled 85 tax avoidance cases yielding €16.5m.
It said that tackling tax and duty non-compliance in all forms and confronting those who use tax-avoidance schemes to gain an unfair advantage remains a key priority for it.
Revenue also completed over 291,000 audit and compliance interventions which yielded €787m during 2023.
Outside of the Debt Warehousing Scheme, a balance of €1.4 billion of unpaid taxes remains available for collection, Revenue said today.
It said the Debt Warehousing Scheme provided a vital liquidity support to businesses from the outset of the Covid-19 pandemic.
Businesses now have until May 1 to make arrangements to repay their warehoused debt.
Revenue Commissioner Ruth Kennedy said that where taxpayers experience challenges in being timely compliant, Revenue strongly encourages them to engage as soon as such difficulties start to emerge so that a mutually agreeable solution that takes account of their financial circumstances can be agreed.
"In the absence of meaningful and timely engagement with Revenue, Revenue will proceed with appropriate collection and enforcement action to recover the debt," Ms Kennedy cautioned.
Looking ahead to 2024, Revenue Chairman Niall Cody said they will be working with affected businesses and agents on the application of the minimum effective corporation tax rules for accounting periods beginning on or after 31 December 2023.
He said that Revenue will issue detailed guidance regarding the implementation of these rules, and actively develop the systems required to enable them to be administered on a self-assessment basis. Revenue will also continue to contribute to ongoing discussions with the OECD, EU Commission and other relevant stakeholders.
Changes from Budget 2024 have also been implemented, and Mr Cody noted that the next few months are the peak period for contacts from PAYE taxpayers.
Meanwhile, the identification, targeting and disruption of shadow economy and other illegal activity, such as smuggling, continued to be a key focus for Revenue last year.
Last year Revenue seized almost 70 million cigarettes valued at over €55m, and a record breaking 9,085 kilos of drugs with an estimated value of almost €302m.
Revenue Commissioner and Director-General of Customs Gerry Harrahill said the the significant level of drug seizures last year included a high profile Joint Task Force operation in September, which comprised members of Revenue's Customs Service, Naval Service and An Garda Síochána, supported by Naval and Air Corps assets and interagency personnel, including the Irish Army Ranger Wing, resulted in the seizure of over €157m worth of cocaine detected onboard the MV Matthew, several arrests and charges before the courts.
Other notable drug seizures in 2023 include the seizure of over €11m worth of cocaine in Rosslare Europort in July, and about €21m worth of cocaine in the Port of Foynes, Limerick, in December.
"The exceptional results achieved in 2023 reflect the hard work and dedication of Revenue's enforcement teams and the excellent working relationships we have with our national and international law enforcement partners," Mr Harrahill said.
