Was granted company stock (US company but working in Ireland) upon starting with them last year. First 25% of stock is due to vest end of this year, with remainder in 25% increments over the next 6 monthly periods.
Now the stock has gone up quite a bit ($25k now worth $40k), so i'm guessing a figure of around $10k will vest.
Can someone tell me how this works? At what stage is tax paid? Do I have to sell the shares to be eligible to pay tax or is tax payable every year?
On what precise figure is the tax paid? Would it be the entire $10k, or simply the increase ($10k minus $6.25k= $3.75k)?
Last question, I know some people make annual deductions from such grants that have vested, how does this work? Do they usually take the difference every year (i.e the increase on the principal?
Any advice would be greatly appreciated.
