I dont believe them to be revenue approved. The shares didnt come through company payroll (they were transferred directly from the share platform) It seems i need to fill out form RTS01 on the basis they were short option shares. I know the total profit, which the sheet calls for but I dont know the tax liability. I assume I'm due to pay income tax on it (all at the higher rate?) I assume I need to pay USC and PAYE? Is the allowance (1250) deductable from the taxable sum (or does it apply at all) What percentages do I work off? Say the profit was €10,000 - Can someone do a mock calculation for me?
