Main Takeaway

Budget 2027 maintains a fiscally prudent stance with no
broad personal income tax rate cuts, while enhancing
targeted supports for households, business investment
incentives, housing supply and climate action.

The below provides a brief overview of the more relevant
changes that may be of interest to corporate entities followed
by a table providing a general overview of the more significant
tax changes brought in by Budget 2027, across all taxes.

Corporate Tax, Research and Development
(R&D) and Capital Markets

Measures aimed at the corporate sector strategically
reinforce Ireland’s reputation as an innovative base, providing
enhanced incentives for research and supporting capital
market participation for indigenous enterprises.

Impact on Corporate Taxpayers

A central component of the budget’s innovation strategy is
the substantial enhancement of the R&D tax credit. The rate
is being increased from 30% to 35%. This enhancement
provides significant encouragement for both multinational
corporations (MNCs) and indigenous companies to base their
high-value innovation activities in Ireland.

Furthermore, the measure includes vital liquidity and
compliance improvements for smaller claimants.The first-year
payment minimum threshold is being raised from €75,000
to €87,500. This adjustment directly enhances cash flow for
Small and Medium Enterprises (SMEs) engaged in R&D,
accelerating their access to state funding.

Implications for Investors and Investment
Funds

In the financial services sector, stability and technical clarity
are prioritised. The exit tax rate applied to payments made
from Irish funds and equivalent offshore funds to Irish
individual investors has been reduced from 41% to 38%. This
adjustment aims to improve retail participation in investment
funds, as it enhances net returns for non-resident and
domestic investors.

Combined with the unchanged 9% value-added tax (VAT) on
property-related services, Ireland’s fund ecosystem retains
competitive cost structures.

In support of capital markets, a new market cap exemption
threshold of €1 billion is introduced for Irish SMEs and startups
trading on regulated markets. For companies falling below
this threshold, the standard 1% stamp duty charge paid on
share transactions will no longer apply. The SME marketcap
threshold stamp duty exemption is aimed at attracting
increased equity financing for growth companies listed on
regulated markets, bolstering liquidity and investor appetite.

Entrepreneurial Incentives and Capital
Gains

To stimulate entrepreneurial activity and reward risk-takers,
the Capital Gains Tax (CGT) Revised Entrepreneur Relief has
been significantly strengthened. The overall lifetime limit on
gains eligible for the reduced 10% CGT rate is increased
from €1 million to €1.5 million. This 50% increase applies to
qualifying disposals made on or after 1 January 2026. This
policy signals a strong commitment to supporting successful
founders and incentivises them to reinvest their capital within
the Irish economy, thereby promoting further start-up creation
and economic dynamism.

In support of capital markets, a new market cap exemption
threshold of €1 billion is introduced for Irish SMEs and startups
trading on regulated markets. For companies falling below
this threshold, the standard 1% stamp duty charge paid on
share transactions will no longer apply.

This measure is positioned as essential for enhancing the
growth prospects of homegrown businesses, particularly
those seeking to secure funding or scale internationally. The
Key Employee Engagement Programme (KEEP) has also been
extended until the end of 2028.

Conclusion

Although from a personal income tax perspective Budget
2027 has a much more targeted and measured approach
to what we’ve seen in previous years, the enhancements
to R&D incentives, fund taxation and SME reliefs should
hopefully lower effective tax burdens for corporates and
investors, foster greater deal activity in growth sectors
and prop up Ireland’s positioning as a tax-efficient hub for
innovation finance.

The below table provides a brief summary of the pertinent
tax changes brought in by Budget 2027. We now wait for
the publication of Finance Bill 2026, to see exactly how
these measures will be implemented.
