share selling, employee shares

Hi all,
I searched but couldnt find the answer so maybe someone here can help please?
I bought shares in a company i worked for when they initially floated on the ISE.
I paid 24c per share though they l floated at €1.32 on the day. I did pay tax to the revenue at the time on advice from someone in finance dept, im not sure what this was but was about 500 euro.
Now in total i have around 5,500 shares and prices are now around 1.50 and my question is if i sell what taxes am i to pay on this, taking into account what i already paid...
Is there an allowance for selling shares etc?
many thanks,
Gibo

i think when you first paid tax it might of been tax on the discount you got.

like 1.32-0.24= 1.08 you paid tax on.

I get your question completely. you are wondering if you will pay tax on the gain you made from the 0.24 to 1.50 or capital gains tax on the 1.32 to the 1.50

In my opinion i think you would pay tax on the 1.32 to 1.50 profit you made.

But i do not know that for certain.
