Ireland KEEP Scheme & Stock Options: SME Tax Guide

Executive Summary

Ireland’s KEEP programme is one of the most startup-friendly equity structures in Europe, but eligibility is narrow. If you confuse KEEP with standard stock options, you can mis-budget tax by tens of percent of the spread.

Dublin’s labor market mixes US HQs (heavy RSU packages) with local startups (options that might qualify for KEEP). The same street can host incompatible tax regimes—your colleague at a different building may describe completely different tax outcomes.

Use this guide with the Ireland country page and relocating with equity. US taxpayers should also read ISO vs NSO and foreign tax planning.

The bottom line: Identify whether your grant is KEEP-qualified before exercise—payroll and brokers will not always label options clearly in employee-facing UIs.

Who this guide helps most: Startup employees with Irish parent companies and documented KEEP grants; Big Tech employees may still benefit from understanding why their RSUs do not use KEEP—clarity reduces false hope in negotiations.

Critical Warning: USC and PRSI rules can change in Budget announcements—verify the year of exercise.

Standard Unapproved Options vs KEEP (Conceptual)

Source: Revenue guidance; simplified for comparison.

Reading the table carefully: The middle column (standard options) is where most employees live. KEEP is the exception—treat it as a narrow corridor with bright-line tests, not a default.

---

Eligibility: Company Size and Structure

KEEP targets smaller employers. Indicators often discussed in commentary include turnover, balance sheet totals, and group rules. Large multinationals or listed parents may fail tests.

Action: Ask your employer for written confirmation of KEEP status and Revenue registration.

Common failure modes

---

Grant Limits and Caps

Negotiation tip: If you are near caps, consider splitting grants across tax years—but commercial vesting schedules may not permit this; align legal and HR early.

---

Exercise and Holding Periods

KEEP options typically cannot be exercised immediately—minimum holding rules exist. Maximum exercise windows also apply.

Documentation: Ask whether your option agreement references KEEP explicitly and includes Revenue registration identifiers—generic Equity Incentive Plan PDFs may not be KEEP.

---

RSUs and Restricted Stock in Ireland

Many large employers in Ireland grant RSUs rather than options. KEEP is option-focused; RSU taxation follows employment income timing on vesting in typical cases—see RSU guide for economics.

---

USC and PRSI: Why Cash Flow Still Surprises

Even when income tax is mitigated, other charges may still appear depending on facts—do not treat KEEP as “tax-free.”

Payroll visibility: Irish payslips may show Gross vs Net deductions that are hard to map to US concepts—maintain employer PDFs annually.

---

ESPP and Purchase Plans

If you participate in an ESPP, read ESPP taxation for US rules and ask Irish payroll for local treatment of discounts—KEEP does not typically cover ESPP purchases.

---

Pension and AVCs

Large equity events may change your pension contribution strategy—AV relief interacts with taxable income. Speak with an Irish financial advisor before making large AVC contributions after a vest.

---

Estimated Tax and Payment on Account

Large exercise events can create balancing payments due in October under Irish self-assessment rules for certain taxpayers—mirror the cash discipline in estimated tax payments (US-framed, but the liquidity lesson applies).

---

US Taxpayers in Ireland

US ISOs: If you exercise ISOs while Irish-resident, US AMT may still apply even if Ireland offers KEEP treatment on a local grant—two different grants, two different analyses. Maintain separate ledgers.

Foreign tax credits: File Form 1116 when appropriate; timing mismatches between countries are common.

---

Comparison: Dublin vs Amsterdam

See Netherlands 30% ruling.

Choosing between hubs: Dublin hosts large US HQs with standard equity programs; Amsterdam offers 30% ruling to many expats. KEEP rarely factors for Big Tech hires—do not anchor negotiations on KEEP if your employer cannot qualify.

---

Why Standard Irish Options Hurt at Exercise

Without KEEP-style relief, unapproved options often generate immediate payroll taxes on the spread at exercise:

This mirrors NSO taxation in the US—see ISO vs NSO—but Irish bands differ.

Cash problem: If shares are illiquid, you may owe tax without sale proceeds—the same cashless issues described in AMT planning.

---

KEEP Mechanics: From Grant to Sale (High Level)

Finance Acts may extend deadlines or adjust caps—treat grant year law as controlling unless rolled forward.

---

Group Structures and Conversions

Acquisitions can invalidate assumptions. If your startup is acquired by a listed parent, KEEP eligibility may lapse or change. Read M&A equity alongside Irish counsel.

---

Tender Offers and Secondary Sales

If your startup provides liquidity via a tender, read secondary markets. Irish tax follows character of proceeds—capital vs employment—and may interact with US reporting if you are a US taxpayer.

---

Token and Crypto Compensation

If you receive tokens, see token compensation. KEEP is share-option oriented—token awards may fall outside KEEP entirely.

---

Year-End Planning and Bonuses

Irish employers often pay bonus and February equity in the same quarter—model stacking like we describe for the Netherlands guide. Link: year-end planning.

---

QSBS and US-Only Reliefs (Do Not Confuse)

Section 1202 QSBS is a US regime for qualified stock—see QSBS guide. Irish KEEP shares may not meet US QSBS tests—do not assume alignment.

---

Practical Examples (EUR)

Example A: Standard option exercise (non-KEEP)

• Spread €50,000 → income tax + USC + PRSI
• Net cash need may be material even before sale

Example B: KEEP-qualified disposal

• Chargeable gain €80,000 → CGT at applicable rate
• Compare effective rates vs standard path

Example C: Big Tech Dublin (non-KEEP)

• €200,000 RSU vest → employment taxes via payroll
• No KEEP—compare with Netherlands 30% or Portugal IFICI packages if negotiating a move

Example D: Partial exercise ladder

You exercise 25% of your options annually to manage cash and liquidity. Irish payroll taxes each exercise increment—multi-year modeling beats one-time spreadsheet guesses. Compare with early exercise break-even.

---

Home Buying and Mortgages

If you use equity proceeds for a deposit, read equity for home buying. Irish lenders differ on RSU income recognition—two years of vest history often helps.

---

Cost Basis and Broker Statements

If you sell shares after exercise, track basis carefully—see cost basis. Irish and US basis may diverge for the same lot.

---

Divorce and Family Law

Equity may be divided in separation agreements—see equity in divorce. KEEP shares may still be illiquid—valuations get contentious.

---

Compliance Checklist

• ☐ Confirm KEEP registration and certificate from employer
• ☐ Track exercise windows and cliff dates
• ☐ File Irish income tax and CGT returns on time
• ☐ US persons: model Form 1116

Comparison: Ireland vs UK vs France (Equity Themes)

This table is not tax advice—only a map for where to research next.

Brexit note: UK–Ireland mobility still exists, but payroll and social insurance coordination differs from the pre-2021 era—equity grants spanning both jurisdictions need extra documentation.

---

FAQs Employees Misread

“Is KEEP automatic?” No—employer must meet tests and register appropriately.

“Is CGT always cheaper than income tax?” Not necessarily—effective rates depend on marginal income tax + USC + PRSI vs 33% CGT on net gains after reliefs.

“Can I file a US 83(b) on Irish options?” US elections do not replace Irish analysis—see 83(b) expats.

“Does my employer’s Carta screen say KEEP?” HRIS labels are not legal opinions—verify grant agreement text.
