Trying to understand this. My daughter worked for 3 weeks in total in 2013 tax year. Her gross earnings were 1,347.59 and prsi was calculated at code AL in total for 34.78. Taking one week for example her gross wages were 443.31 and the prsi deducted was 12.65. That works out at an odd 2.5756%. Was this correct and is she entitled to any rebate. Thanks.
