Hello, I am receiving a bonus of 3,555 euro from the company that I work for , I am allowed purchase shares of 2,642 euro leaving me with 913 euro, As far as I can gather I can invest this 913 euro in with forgone salary between March and September , My worry is should I just invest the 2,642 euro I am allowed to invest and hold back the rest for PRSI and USC charges , This is the first year my shares have matured so I am fairly clueless , Thanks in advance for any help .
