How are RSUs taxed in Ireland?

RSUs are taxed at vesting as employment income. You pay Income Tax (20%/40%), USC, and PRSI on the market value of the shares at the date they vest. Your employer typically withholds the tax through payroll. If you later sell the shares at a profit above the vesting price, you also pay CGT at 33% on that additional gain.

What are restricted stock units in Ireland?

RSUs are a form of equity compensation where your employer promises to give you company shares after a vesting period (typically 3–4 years). Unlike share options, RSUs have value even if the share price falls. They are commonly used by multinational tech companies operating in Ireland.

Is there capital gains tax on RSU in Ireland?

Yes, if you sell your vested RSU shares at a price higher than their market value at vesting, the profit is subject to CGT at 33%. You are personally responsible for filing and paying this — it is not handled by your employer. The annual CGT exemption of €1,270 applies. CGT returns are due by 31 October following the year of disposal.

Do you pay tax on stock gains in Ireland?

Yes, profits from selling shares in Ireland are subject to Capital Gains Tax at 33%. The gain is the difference between the sale price and the acquisition cost (including allowable expenses). The first €1,270 of gains per year is exempt. For RSUs, the acquisition cost is the market value at vesting (on which you already paid income tax).

RSU Tax Ireland 2026: How RSUs Are Taxed & What You Owe

In today’s tech-driven economy, more and more Irish employees are being rewarded with Restricted Stock Units (RSUs). They’re a fantastic way to share in your employer’s growth, but they also bring serious tax complications.

Employees often assume RSUs are “free shares.” In reality, RSUs trigger income tax, USC, PRSI, and potentially Capital Gains Tax (CGT) at different stages. If you’ve moved countries, changed residency, or are non-domiciled in Ireland, things get even more complicated.

At Irish Tax Hub, we specialise in helping employees, directors, and international assignees navigate RSU taxation in Ireland. We’ve seen every type of edge case - from cross-border vesting to double taxation issues - and we know how to optimise your outcome.

What Are RSUs?

Restricted Stock Units are a type of deferred compensation. Instead of cash, your employer grants you units that convert into shares (or cash equivalent) once conditions are met.

Grant Date: You’re promised RSUs but no tax event yet.
Vesting Date: RSUs convert to actual shares or cash → tax event.
Sale Date: If you sell shares, CGT may apply on any gain.

This three-stage lifecycle is where tax complexity arises.

When Are RSUs Taxed in Ireland?

RSUs are taxable at vesting if you are resident in Ireland. Revenue treats the value of RSUs at vest as income, just like salary. That means:

Income Tax (20% or 40% depending on band).
Universal Social Charge (USC) (up to 8%).
PRSI (usually 4.2%).

That’s often over 50% tax on the vest value.

Then, if you later sell the shares at a higher price, you pay 33% CGT on the difference between the vesting value (your “base cost”) and sale proceeds.

How Employers Handle RSU Tax

Most companies apply a sell-to-cover mechanism: they sell part of your vested shares to cover the tax liability and remit it via payroll. Typically, around 52.2% of vested shares disappear instantly to satisfy PAYE, USC, and PRSI.

But employers don’t track CGT liabilities for you - that’s your responsibility. This is where many employees slip up, because CGT must be:

Self-reported and paid by 15 December for gains realised between Jan–Nov.
Self-reported and paid by 31 January for gains in December.

At Irish Tax Hub, we help clients avoid late CGT penalties by handling reporting and payment deadlines correctly.

Worked Example: Standard RSU Vest

Claire works at a Dublin tech firm:

600 RSUs vest on 1 July 2026, market value €70 per share = €42,000.
Income Tax (40%): €16,800
USC (8%): €3,360
PRSI (4.2%): €1,764
Total tax = €21,924, withheld via payroll.

She keeps the remaining shares. In December, she sells them at €75 per share, realising €3,000 profit.

CGT ((€3,000-€1,270) x 33%) = €570.90, payable by 31 January 2027.

Claire’s employer handles PAYE, but only Irish Tax Hub ensures her CGT is declared, reliefs applied, and everything reported on her Form 11.

Scenario Analysis: Where It Gets Complicated

1. Cross-Border Vesting

Many employees earn RSUs while working abroad, then move to Ireland before vesting. Key issue: Ireland taxes RSUs only if you’re resident when they vest. There is no pro-rata split based on where you worked.

Example: You work in the UK for 18 months, then relocate to Dublin. RSUs vest after 2 years. Ireland will tax the full value at vest, even though most of the work was abroad. The UK may also tax - creating a double taxation risk.

Irish Tax Hub Tip: We apply Double Taxation Agreements (DTAs) to claim credits and eliminate double tax exposure.

2. RSUs Paid in Cash vs Shares

Cash-settled RSUs: Treated purely as employment income - no CGT later.
Share-settled RSUs: Employment income at vesting, then potential CGT at sale.

Mixing both creates hybrid reporting. Employers don’t always explain this clearly, but Irish Tax Hub ensures correct treatment on your Form 11 or Form 12.

3. Departure from Ireland

If you leave Ireland mid-year and RSUs vest after you’ve left, Ireland won’t tax them. But your new country may tax the full value.

This can leave you struggling to get foreign tax credits. Our team at Irish Tax Hub coordinates multi-country RSU tax reporting to avoid costly overlaps.

Common Pitfalls with RSUs in Ireland

Assuming the employer handles all taxes (they don’t handle CGT).
Forgetting the CGT deadlines (15 December and 31 January).
Mixing RSU shares with other investments and losing track of base costs.
Overpaying tax by not claiming treaty credits.
Triggering unexpected liabilities when moving abroad.
