paying taxes on RSUs upon selling

You already paid tax on the RSU on deemed value when they vested. That would have a value given on your salary /wage slip, along with a value per share used for tax purposes in your brokerage account (eg etrade).

If you sell at higher than the deemed value you made a profit and you need to pay CG tax on that. First 1k (i think) is written off.

In your example, you were given the RSUs at 100euro , and the tax was already applied at that, so if you sell at 110, you need to pay CGT on the 10 euro.

Unless you're talking about shares you bought as part of an ESPP/ESOT , in which case you need to pay BIK on fair market value less the acquisition price, and then CGT on sale price minus fair market value at acquisition

Yes the tax is listed in etrade. It will be something listed in the part where they display the witholding tax - this display would change depending on your company's settings.

I think it's a form 11 you have to fill out with revenue but I do stand to be corrected on that one.

If you make a capital gain (or loss) when selling your RSUs (based on their sale price compared to the value of the shares when they were actually issued to you on the vesting date), you'll usually report that on a Form CG1, assuming that you aren't registered for self-assessment and don't otherwise have to file a Form 11. See this Revenue page for details. If you are already registered for self-assessment (e.g. because you have significant non-PAYE income), then you'd report those capital gains on your Form 11 instead.

Note that you must pay any CGT liability in the year it was actually incurred, not in the year you file the relevant CGT return. If you sold RSUs today, for example, you'd have to report that sale on your Form CG1 by October 2024, but you'd have to pay the CGT you owe on those sales before December 15th 2023. Bit of a silly system, all in all, but the taxman wants his money now, not later, so that's just how it is.

Yes.

Have you a reference for that about grant date being the base/acquisition cost? My understanding and everything I've seen has suggested the value at vesting is to be considered as the "purchase" cost, and gains are anything in excess of this, with the grant date being moot.

That was my understanding too, so thanks for clarifying as you had me wondering!

I'm pretty sure the grant date value for RSUs is only used in a notional sense, where the company may use it to calculate/assert the employee's total compensation package in a year, even though the employee won't actually receive the benefit of that for some time to come (vest date or dates), and the value may be very different then.

Bumping.....I sold a few vested RSU's last week and made ca. 500 euro on them. As such I'm below the 1270 euro threshold for CGT but I have no idea how the heck to deal with the Revenue.ie site to declare that I sold them - I keep hearing that I have to let Revenue know but how the heck do I do that...

Despite asking lots of people I get links to the Revenue site but that doesn't actually provide any details of exactly what to do in terms of forms or anything. The forms I've seen on there are absolute monsters and I wouldn't even know how to start on them.

I have posted an enquiry to them with details of the shares and transactions and maybe they will come back with some instructions but it's brutal trying to find out EXACTLY what to do.

Thanks, I presume I just fill out the relevant section? What the heck is my "Tax Reference Number"?

Oh! Right, thanks.
