I never had reason to fully understand the tax system and hence my queries may appear simple to explain. A person starts work with the HSE in July last with gross weekly pay of 744.33 and after pension levy and pension taxable pay is 7o7.88. On the payslip tax and PRSI are ok but USC is 59.54 which seems way out of line? the tax credit is 64 euros which is 1/52 of 33OO and i am wondering when allowance will be given for the total tax credits from the start of the year. Any clarification would be appreciated.
