ESPP in Ireland Explained
I took my ESPP every single period for eleven years. Twenty periods in total.
It was the best financial decision I made at Salesforce and, for a while, also one of my worst. Both things are true, and the gap between them is the whole lesson.
Let me explain how an ESPP works in Ireland, how it's taxed, and where the money is won and lost.
What an ESPP actually is
An Employee Share Purchase Plan lets you buy your company's shares through payroll, usually at a discount.
You set aside a fixed amount from each paycheck over an offer period, normally six months. At the end of the period the company uses that pot to buy shares for you, typically at up to 15% below the market price, often based on the lower of the price at the start or the end of the period.
That discount is close to free money. In my eleven years the share price rose in eighteen of the twenty periods, so my real discount regularly beat the headline 15%. In 2023 alone the after-tax value of that discount was worth about 11,000 euro to me.
If your employer offers an ESPP and you can afford the contributions, the discount is one of the best-value perks in tech.
How the ESPP discount is taxed in Ireland
Here's what changed and what trips people up.
Since 1 January 2024, the discount is taxed as income at source through payroll. So on the day the shares are bought for you, Income Tax, USC and PRSI come off the discount amount, the same way they do on RSUs. You no longer file the old RTSO1 form for it.
The amount taxed is the difference between the market value when the shares are bought and what you actually paid. That's the benefit, so that's what's taxed as income.
Before 2024 you had to calculate and pay this yourself within 30 days. Many people didn't, and built up a quiet problem. The new payroll system removes that trap, which is a real improvement.
The second tax: when you sell
After purchase, the ESPP shares behave like any other shares.
If you sell later for more than their value at purchase, the growth is a capital gain. You pay Capital Gains Tax at 33% on the gain above a 1,270 euro annual exemption, and you report it to Revenue yourself. Same rules as RSUs.
My expensive mistake
I got the discount right. I got the holding wrong.
Period after period, I kept the shares instead of selling. They piled up until roughly a third of my entire net worth was tied to the one company that also paid my salary, my bonus and my pension. If Salesforce had stumbled, everything would have moved together.
In early 2020 I finally added it all up: 191,000 euro, far too much of it in Salesforce. On 31 March 2020, in the middle of the Covid crash, I sold all my Salesforce shares and reinvested into the whole market. A friend told me I was crazy. Salesforce then doubled in five months. Then the wider market overtook it, and since then the broad market has run far ahead.
The point is not that I timed anything. I didn't. The point is I stopped betting my freedom on one stock.
The simple ESPP playbook
What I teach now, and do myself:
- Take the discount every period you can afford it.
- Sell the shares on the day they land. The discount is the prize, not the holding.
- Reinvest into a low-cost global index fund.
- Before all of this, max your pension, because that's the biggest tax break you already have.

Frequently asked questions
Is an ESPP worth it in Ireland?
For most people who can afford the contributions, yes. The discount of up to 15% is strong value. The key is to sell the shares promptly rather than building a concentrated holding in your employer.
How is the ESPP discount taxed in Ireland?
Since 1 January 2024 the discount is taxed as income (Income Tax, USC and PRSI) through payroll on the day the shares are purchased. Any later growth is taxed at 33% CGT when you sell.
Do I still file an RTSO1 for my ESPP?
No. From 2024 the income tax on the discount is collected through payroll, so the old RTSO1 self-payment for ESPP no longer applies.
Should I hold or sell my ESPP shares?
Selling on or near the purchase date and diversifying into a global index fund removes the risk of being over-exposed to your own employer with money that has already been taxed.
