EIIS in Ireland: How the Employment Investment Incentive Works

The Employment Investment Incentive (EII), sometimes referred to as EIIS, is an Irish income tax relief for individuals who invest in the shares of qualifying trading companies. Revenue's own pages call it the Employment Investment Incentive (EII), so you will see both names. This guide explains how the scheme is structured, what Revenue's guidance says about companies and investors, and where the rules need careful checking before anyone relies on them. It is a general overview, not tax advice.

EII is a scheme for outside investors putting money into a company. It is different from the arrangements a company may use to reward its own staff, which we cover in our guide to employee share schemes and KEEP share options.

What EII is, according to Revenue

Revenue's EII page (shown as last updated on 23 April 2026) describes the relief as a tax relief intended to encourage individuals to provide equity-based finance to trading companies. Revenue's Tax and Duty Manual overview (Part 16-00-02A, created December 2025) places EII alongside two related reliefs under Part 16 of the Taxes Consolidation Act 1997:

• Employment Investment Incentive (EII): relief for individuals who are not connected with the company and who subscribe for new shares in a round of risk financing.
• Start-Up Capital Incentive (SCI): similar to EII, but for investors connected with the company, often in a family business. Only micro companies can raise funds under SCI.
• Start-Up Relief for Entrepreneurs (SURE): aimed at people who leave employment to start their own company.

Revenue has split its detailed guidance into separate manuals: an overview, one for the company side (Part 16-00-03), one for the investor side (Part 16-00-04) and one for SURE (Part 16-00-05). Older versions of limits and conditions can be reached through the "show older versions" option on Revenue's Part 16 page, which matters when you are dealing with an investment made some years ago.

The investor side

According to the investor manual (created December 2025), a qualifying investor is an individual who subscribes for new shares in a qualifying company for cash. The investment can be made directly or, for EII, through a Designated Investment Fund or a Qualifying Investment Fund. The main points the manual makes are:

• Unconnected investors. Under EII the investor must not be connected with the company during a compliance period that runs from two years before the shares are issued to four years after. Connection includes being, or having an associate who is, a partner, director or employee of the company or its group, or having an interest in its capital. Directors and employees are not treated as connected if they receive only reasonable payments such as expenses, market-rate interest or normal dividends.
• Genuine, new shares. Shares must be new and issued for cash. Shares issued for wages, for no consideration or on conversion of a director's loan are not eligible, and, outside the QIF fund-manager exception described in the manual, they must not carry preferential dividend or winding-up rights.
• No risk-reducing arrangements. The manual says there must be no arrangements that substantially reduce the investment risk or guarantee repayment of capital or dividends.
• Holding period. Eligible shares must be held for four years.

The manual also sets a minimum individual investment, which does not apply to investments through a fund. We have not repeated every figure here because they are specific to the date of the investment.

How the relief works

The investor manual describes the relief as a deduction from total income, calculated as a percentage of the amount invested, with the percentage depending on the type of investment (initial, follow-on or expansion) and the age of the company's group. Actual tax saved depends on whether the investor has enough income taxed at the higher rate to absorb the deduction. Unused relief may be carried forward, and the manual says relief for earlier investments is given first.

To claim, the investor needs a Statement of Qualification from the company, or a Manager's Certificate for fund investments, and claims on Form 11 or Form 12. The manual says the company must issue the statement by 31 December of the year after the year in which the shares were issued. The Revenue EII page adds that, for shares issued after 8 October 2019, relief is available in full in the year of investment.

Where Revenue's pages differ on the annual limit

Two Revenue sources give different pictures of the annual investment cap. The EII page (23 April 2026) lists a cap of 150,000 euro for years up to and including 2019, then 500,000 euro for later years where shares are held for at least seven years, or 250,000 euro where they are held for four years. The Tax and Duty Manuals (December 2025) refer instead to an annual cap of 1,000,000 euro combined across the Part 16 reliefs for investments made on or after 1 January 2025, and say the previous limit was 500,000 euro. We assert neither version. Our suggestion: anyone planning an investment should confirm the limit that applies on the date of issue with Revenue or a tax adviser, and keep a note of which source they relied on.

The company side

The company manual (Part 16-00-03) sets out the conditions a company must meet. In summary, at the time of investment the company must be incorporated in Ireland, another EEA state or the UK, hold a valid tax clearance certificate, have a business plan for the investment, and exist wholly for relevant trading activities or as a holding company. Each company in the group must be unlisted and an SME that is not an undertaking in difficulty. Throughout the relevant period, which runs for four years from the issue of shares, it must be tax resident in one of those places, carry on relevant trading activities from a fixed place of business in Ireland, and have fully paid-up shares.

Relevant trading activities are trades taxed under Case I of Schedule D. The manual lists excluded activities, including dealing in financial assets, a range of professional services, dealing in or developing land, hotel operation (with an exception for tourist traffic undertakings) and certain other sectors. Internationally traded financial services need a certificate from Enterprise Ireland, and tourist traffic undertakings need the relevant tourism authority's approval of a development and marketing plan. Because the exclusions are detailed, a company should read the manual itself rather than rely on a summary.

The manual also describes a "subsequent period" ending three years after the investment is received. At that point the company must meet one of three tests set out in the manual (an increase in qualifying employees, an increase in emoluments paid to them, or higher research, development and innovation expenditure, compared with the year before the shares were issued), or an amount of relief is withdrawn. The manual notes a different combination for shares issued up to 31 December 2024. Companies that also claim the research and development tax credit may find our guide to the R&D tax credit in Ireland useful alongside this test.

Reporting and State aid

Revenue explains that EII operates as permitted State aid under the General Block Exemption Regulation. For companies this brings reporting duties: qualifying investments are reported on the corporation tax return and through a return filed on the Revenue Online Service, and the manual says investment details are published on Revenue's website because of State aid rules. The manual states a deadline for the return and a penalty for non-compliance. As deadlines change, check the manual on the day. The manual also names a Form 21R for nominee reporting.

The manuals we read refer to the Statement of Qualification and the company return rather than to form names such as EIIS1 or EIIS2. If you come across those names elsewhere, check them against Revenue's current guidance.

Withdrawal of relief and capital gains

The investor manual explains that relief can be withdrawn if it was not due, if the investor enters risk-reducing arrangements, or if the investor ceases to qualify. A disposal at arm's length before the end of the period reduces the relief by the proceeds received, while a non-arm's-length disposal triggers full withdrawal. Withdrawal is made by an assessment on the investor. On capital gains, the manual says a CGT liability arises on a gain, loss relief is not available, and the calculation is restricted by the income tax relief given, so a disposal normally produces neither a gain nor a loss.

Timing and checks

The manuals say relief applies to eligible shares issued on or before 31 December 2026. Revenue's pages do not say what happens after that, and legislation can change. Check Revenue's current EII page before any decision.

A practical approach: keep the Statement of Qualification, the share subscription documents and the correspondence about connection and holding periods in one file, and diarise the end of the four-year period. For finance teams and advisers who handle these claims, keeping up to date matters, and our overview of CPD training for finance professionals in Dublin is a starting point.

Frequently asked questions

Is EIIS the same as EII?

EIIS is a name sometimes used for the scheme. Revenue's pages and manuals refer to the Employment Investment Incentive (EII), and describe it as one of three Part 16 reliefs alongside SCI and SURE.

Can a director or employee of the company claim EII?

Under the investor manual, an investor connected with the company during the compliance period is not eligible for EII. Directors and employees are not treated as connected if they receive only reasonable payments, but connection rules are detailed, so check the manual.

How long must the shares be held?

Revenue's pages say eligible shares must be held for four years. The EII page also links the higher annual cap shown there to a seven-year holding period; see the section above on the differing limits.

What happens if the investor sells early?

The manual says a disposal before the end of the compliance period generally reduces or withdraws the relief, with the exact effect depending on whether the sale is at arm's length.

Where can I check the current rules?

Use Revenue's EII page and Tax and Duty Manual Part 16 on revenue.ie. Figures, dates and conditions change, so confirm them on the day.
