Taxes are often a reflection of a nation’s priorities, its political will, and its economic trajectory. In Ireland, taxation has played a pivotal role in shaping the country’s fiscal framework, transforming it from a newly independent Free State in the early 20th century into one of Europe’s most attractive economies for investment and innovation.
In this blog, we explore the history of tax in Ireland, the major reforms that followed, the types of taxes that exist today, and why Ireland’s tax policies are often debated globally. Whether you’re curious about income tax Ireland history, tax in Ireland for non-residents, or wondering why Ireland is so wealthy, this guide has you covered.
A Century of Taxation: The Origins of Revenue in Ireland
The official story of modern taxation in Ireland begins with the formation of Revenue, or the Revenue Commissioners, on 21 February 1923, under the authority of the newly formed Free State Government. The establishment of Revenue was a crucial step in transitioning control from British rule to Irish sovereignty.
Originally formed through Order 2/23 by the Oireachtas, the new structure created a single Board of three Commissioners. The first chairman, William O’Brien from Cappamore, County Limerick, was joined by Corkmen Charles Joseph Flynn and William Denis Carey—each bringing extensive experience from the UK Inland Revenue and Customs & Excise departments.
While the administrative transfer from Britain to the Free State began on 1 April 1922, it wasn’t until April 1923 that full operational control passed to Revenue. During the transitional phase, the UK authorities still collected 1922/23 liabilities on Ireland’s behalf, passing on all proceeds—even from pre-Treaty debts—to the new Irish Exchequer.
The main areas of revenue collection at the time were income tax, customs duties, and excise duties, forming the foundation of what would evolve into today’s multifaceted Irish tax system.
When Was Income Tax Introduced in Ireland?
Although Revenue was formed in 1923, income tax in Ireland actually dates back to the 19th century under British rule. The modern structure, however, was formally developed and managed by the Irish government after independence.
For those curious about historical rates, the income tax rate in Ireland in 1983 was a whopping 60% at the top bracket, reflecting the high-tax economic climate of the time. In contrast, today’s marginal rates are far lower, showing how Ireland has restructured its economy over the years.

When Was Corporation Tax Introduced in Ireland?
Ireland’s corporation tax has become world-renowned—often controversial—due to its low rate. Introduced in 1976, Ireland set the stage for what many critics and advocates call its status as a “tax haven.” By the late 1990s, Ireland locked in a 12.5% corporate tax rate for trading income—a figure that would lure giants like Google, Apple, and Facebook.
Although this sparked debates on how long Ireland has been a tax haven, Irish authorities defend the model as a legitimate, competitive strategy to attract foreign direct investment (FDI) and spur domestic innovation.

Who Is Exempt from Paying Tax in Ireland?
Certain individuals are exempt or partially exempt from paying tax in Ireland:
-
Individuals earning below the exemption limits
-
People over 65 with income below a specified threshold
-
Certain pensioners
-
Some welfare recipients
-
Charitable organizations (with regard to their qualifying income)
However, these exemptions apply to income tax primarily. Other taxes such as VAT or PRSI may still apply depending on circumstances.
Ireland’s Tax Reforms: When Did It Cut Taxes?
Major tax reforms occurred in the late 1980s and 1990s, as Ireland sought to modernize its economy. High income tax rates—once as high as 60%—were gradually slashed, and the corporation tax rate was dropped to 12.5%, placing Ireland firmly on the map as a business-friendly jurisdiction.
These cuts were instrumental in attracting tech giants, establishing the Celtic Tiger era, and propelling Ireland to one of the fastest-growing economies in Europe.
Is Ireland a Tax Haven?
Whether or not Ireland qualifies as a tax haven depends on your definition. The country boasts transparent tax laws, membership in the EU and OECD, and stringent reporting standards. However, the low corporate tax rate, coupled with generous R&D credits and tax treaties, has led critics to label it as such.
That said, Ireland has cooperated with international bodies and committed to global tax reform, including the recent OECD agreement on a 15% minimum corporate tax rate.
What Is the Oldest Tax in the World?
While not unique to Ireland, the concept of taxation dates back thousands of years. The oldest known tax system is believed to originate in ancient Egypt, around 3000 BCE, where citizens paid taxes in goods and labor.
In an Irish context, taxation under British rule was heavily focused on land taxes, tithes, and customs duties, all of which played into Ireland’s agrarian economy and colonial history.
Why Is Ireland So Wealthy?
Despite its small size, Ireland consistently ranks among the wealthiest nations in the world by GDP per capita. Several factors contribute:
-
Favorable corporate tax rates
-
A highly educated workforce
-
Membership in the European Union
-
Strategic focus on technology, pharmaceuticals, and finance
-
A thriving export economy
Ireland’s tax strategy, particularly the corporation tax policy, played a key role in attracting FDI and fueling economic growth—though not without controversy.
