Sorting your CGT shouldn't be this hard
If you've sold shares, received employee equity, or traded crypto in Ireland, you already know the frustration.
The options aren't great
Accountants can easily charge €400 or more per year for CGT work, and many won't take on small cases at all. Doing it yourself means navigating FIFO, 28-day rules, and FX conversions in a spreadsheet. Either way, it's stressful.
The money disappears
You sell shares, the proceeds hit your account, life happens. When the tax bill arrives months later, the money's already gone.
There's no clear alternative
No affordable way to handle it yourself with confidence. No tool that helps you understand what you owe and take control of your own tax obligations.

What our customers say
Real testimonials from professionals who've made CGT simple with Submyt
"I tried for a long time to figure out how to calculate my CGT after selling stocks. Once I added my transactions to Submyt, the platform did the rest and I knew exactly how much I had to pay. Doing all of this manually would make you old before the time. Simply put, if you own stocks, Submyt is a must have."
"I had been struggling for months trying to understand the Capital Gains Tax I owed on my sold shares. The whole process was stressful and confusing. Then I discovered Submyt, and it completely changed the game for me. The relief I felt went from constant stress and uncertainty to peace of mind knowing it was done, and done right."
