OK I am going to attempt to do this myself - I am an Architect by Profession - I earn a Salary of 80,000 plus 10,000 Bonus giving 90,000. During 2008 , I did Three Nixers I received €2,160, I also received a divedevd from Shares for €252.00, taking account of 42% tax and PRSI how do I do the math and fill in form and then do I simply write cheque and forward to Revenue? Thanks in advance
