An Employee Share Ownership Plan, usually shortened to ESOP, is one of the most powerful tools an Irish startup or growing company has for hiring and keeping top talent without spending cash it does not yet have. Done correctly, an ESOP turns employees into shareholders, aligns their incentives with the long-term success of the company, and meaningfully reduces the cash cost of building a senior team. Done late, or done badly, it can create unexpected tax bills, governance headaches, and a cap table that founders later wish they had structured differently.
This article walks through what an ESOP actually is in an Irish context, when to put one in place, the difference between giving employees shares now versus granting share options, and the main tax-efficient structures Revenue allows. It draws on practical advice from Sean Wallace of Wallace Corporate Counsel and the experience we have helping clients design and implement schemes at Kinore.
What is an Employee Share Ownership Plan in Ireland?
An ESOP is any structured arrangement where a company gives employees either shares in the business or the right to acquire shares in the future. In Ireland, ESOPs are most common in private limited companies and especially in venture-backed startups, although established SMEs increasingly use them for senior hires and as part of succession planning.
The plan itself is a layered document: the company’s constitution must permit the scheme, the shareholders’ agreement should reflect the option pool, the board approves grants under a written plan rules document, and each employee receives a personal grant letter setting out their specific entitlement. Each layer matters because Revenue, the Companies Registration Office, and any future investor will scrutinise the documentation when they look at the company.
Why do Irish startups use ESOPs?
The reasons fall into three categories: recruitment, retention, and motivation.
- Recruitment. An early-stage startup paying €60,000 for a senior engineer is competing against a multinational paying €120,000. Offering a meaningful slice of equity, say 0.5% to 2% over a four-year vest, closes that gap and signals that the company expects to be worth something significant in the years ahead
- Retention. Vesting schedules tie ownership to the employee’s continued service. A typical pattern is four-year vesting with a one-year cliff, so an employee who leaves after eleven months gets nothing, while an employee who stays the course earns their full grant
- Motivation. An employee who owns part of the upside thinks about the business differently. They ask better questions in meetings, they care about cost, they push harder for growth, and they tend to stay through the difficult quarters
The cultural shift toward an ownership mindset is the part founders often underestimate. A team of 10 employees who each own a small piece of the company behaves differently from a team of 10 paid contractors, and that difference is amplified in the first three years.
When should you implement an ESOP to maximise tax efficiency?
The honest answer is “as early as you reasonably can”. The first 12 to 18 months of a startup is the sweet spot for setting up a share scheme, and there are two related reasons why delaying gets more expensive over time.
The first reason is valuation. When you grant share options at a low strike price tied to a low company valuation, the employee’s potential upside is large, the tax cost on exercise is small (because the company is worth little when the option is granted), and the documentation supporting the strike price is easy to defend. Wait two years, raise a funding round at a €5 million valuation, and the same options become significantly more expensive to grant in tax terms.
The second reason is administration. Setting up an ESOP before you have ten employees is faster, simpler and cheaper than retrofitting one once you have a team that needs to be slotted in retrospectively. Investors in subsequent rounds will also expect to see a properly sized option pool already in place; carving one out later usually dilutes founders more than carving it out early.
Before you launch the scheme, get the following in place:
- A cap table plan with a sized option pool (typically 10% to 15% for venture-backed startups, less for bootstrapped businesses)
- A valuation approach and documentation trail, often supported by a recent funding round or an independent valuation
- Board and shareholder approvals captured in proper minutes and resolutions
- Tax-efficient scheme rules drafted by a solicitor experienced in Irish share schemes
- An accountant briefed to handle the reporting and PAYE implications
Should you give employees shares or share options?
This is the central design choice, and it affects everything from tax timing to who appears on the public CRO register.
| Feature | Direct shares | Share options |
| What the employee gets | Immediate shareholder status from grant date | The right to buy shares later at a set price |
| Public visibility | Name appears on the CRO public register | Confidential until exercised |
| Tax timing | Income tax / USC / PRSI charged at acquisition on market value less price paid | No tax on grant; charged on exercise based on gain |
| Voting and dividends | Full rights unless restricted by share class | None until exercise |
| Best for | Very early stage, founder-led teams, low valuations | Larger teams, scaling companies, confidentiality required |
| Administration burden | Higher: every new shareholder needs to be filed with the CRO | Lower until exercise; cleaner cap table during scaling |
For most Irish startups, share options are the default choice once the company is past the very earliest stage. They keep the cap table simple, they protect founder control, they are easier to claw back if an employee leaves before vesting, and they defer the employee’s tax event to a moment when the value is more likely to be realisable in cash.
When does giving direct shares make more sense?
Direct shares can be the better choice for very early co-founder-level hires (the first one or two senior people who joined when there was effectively no company yet), for family businesses bringing the next generation in, or for situations where the company specifically wants the employee to act and feel like a shareholder from day one. The trade-off is the immediate tax cost and the loss of confidentiality on the CRO register.
What tax-efficient share schemes does Revenue approve in Ireland?
Revenue operates several Approved share schemes and one specifically aimed at SMEs that offer significant tax advantages over an unapproved (vanilla) option grant.
- Key Employee Engagement Programme (KEEP). A tax-efficient share option scheme for qualifying SMEs. KEEP options are taxed at capital gains tax rates on disposal rather than income tax rates on exercise, which can mean a tax saving of around 20 percentage points for the employee. Strict eligibility rules apply on company size, sector, and employee role
- Approved Profit Sharing Schemes (APSS). The company can give each employee up to €12,700 of shares per year free of income tax (USC and PRSI still apply), provided the shares are held in a trust for at least three years. Common in larger and listed companies
- Save As You Earn (SAYE). A monthly savings scheme linked to share options. Employees save up to €500 a month for three or five years, then use the savings to buy shares at a discount. Usually only relevant for larger employers
- Restricted Stock (forfeitable share) schemes. Shares with restrictions on transfer reduce the upfront taxable benefit on acquisition, often by 30% to 60% depending on the restriction period
For most early-stage Irish startups, KEEP is the headline scheme to investigate first. The eligibility rules are tighter than they look at first glance, particularly around qualifying trade activities and the share value thresholds, so do not assume the company qualifies until your solicitor and accountant have confirmed it in writing.
How do ESOPs typically work for the employee?
From the employee’s perspective, a well-structured option grant follows a predictable path:
- Grant. The employee receives a written grant of options at a fixed strike price, with a stated vesting schedule
- Vesting. Options vest over time, usually four years with a one-year cliff. An employee who leaves before the cliff loses the entire grant; after the cliff, vesting is monthly or quarterly
- Exercise. When the employee decides to convert vested options into actual shares, they pay the strike price and (for unapproved options) the income tax, USC and PRSI on the gain
- Sale or exit. When the company is sold or the employee disposes of the shares, capital gains tax applies on any further gain above the value at exercise
Employees frequently underestimate the income tax bill on exercise, especially when the company has grown significantly between grant and exercise. The tax is payable within 30 days of exercise under the RTSO regime for unapproved options, so the employee needs cash on hand or a “cashless exercise” mechanism built into the scheme.
What are the company’s obligations as the employer?
The employer carries the heavier administrative burden. The company must:
- File Form ESS1 with Revenue annually, listing all share scheme activity
- Operate PAYE on certain types of share-based remuneration where the company is required to do so
- Maintain a register of all grants, exercises, lapses, and forfeitures
- Update the cap table and any shareholder agreement schedules as options are exercised
- File new shareholder details with the CRO when options become shares
- Communicate clearly with employees about valuations, exercise windows, and tax implications
The reporting requirements have tightened in recent years, and Revenue audits of share scheme reporting have become more common. Treating the ESOP as a serious legal and tax exercise from day one is significantly cheaper than fixing missed filings later.
Common ESOP mistakes Irish founders make
The most common mistakes we see are predictable and avoidable:
- Waiting until after a funding round to set up the scheme, then grappling with a higher valuation
- Promising “10% equity” verbally and never documenting the grant in writing
- Using a generic template scheme that does not qualify for KEEP or any other Revenue-approved structure
- Forgetting to file Form ESS1 with Revenue at year-end
- Granting options at a strike price that cannot be defended on valuation grounds
- Failing to plan for the tax cash flow when options are exercised
Each of these is fixable when caught early. The hardest mistakes to undo are documentation errors that surface during due diligence at a funding round or acquisition, by which point the cost of correction can run into tens of thousands of euro and can occasionally jeopardise the deal itself.

Frequently asked questions about ESOPs in Ireland
Is an ESOP the same as KEEP in Ireland?
No. ESOP is the general term for any plan that gives employees shares or share options. KEEP is one specific tax-efficient flavour of ESOP, approved by Revenue, that taxes the eventual gain at capital gains tax rates rather than income tax rates. Most Irish startups aim to design their ESOP as a KEEP-qualifying scheme where they can, but not every company or role qualifies.
How much equity should a startup set aside in an option pool?
Venture-backed Irish startups typically reserve 10% to 15% of fully-diluted equity for the employee option pool at seed stage, sometimes extended to 20% by Series A. Bootstrapped companies often use a smaller pool, around 5% to 10%, because they are not under investor pressure to maintain a large reserve for future hires.
What happens to an employee’s options if they leave the company?
Unvested options lapse on the date the employee leaves. Vested options usually need to be exercised within 30 to 90 days of departure or they also lapse, depending on the scheme rules. Good leavers (resignation in normal circumstances) and bad leavers (gross misconduct) are usually treated differently in the plan rules, with bad leavers often losing even vested options.
Does the employee pay tax when options are granted?
No, not for share options. Tax arises on exercise (for unapproved options) or on disposal (for KEEP-qualifying options), not at the grant date. Direct share awards are different; those trigger income tax, USC and PRSI on the market value of the shares at the date of acquisition.
Can my company use an ESOP if we are not venture-backed?
Yes. ESOPs work just as well for bootstrapped companies, family businesses, and established SMEs as they do for funded startups. The structure may be simpler (a small option pool covering one or two senior hires, for example) but the principles are the same. Many family-run Irish businesses use share schemes to bring the next generation into ownership ahead of a planned succession.
