Hi Raul
Not sure about the share awards. Are you sure it's not share option scheme (ESOP) as they're treated differently.
Re your credits, you need to go into the "Personal Tax Credits" section and claim the PAYE tax credit. That brings your credits to €3,660. As for the other €153, that depends on your personal circumstances. It may be that €765 has been awarded as Schedule E expenses, giving you an additional €153 tax credits but that would seem very excessive (normally approx €100). You best get onto your local Paye Section (1890-333425 for Dublin) to get a breakdown of the €3,813.
