Brit5Alpha.....does your daughter have to pay National Insurance Contributions?
If so,
THIS is an Income Tax and National Insurance Calculator.
I assume your daughter recieves a Payslip? I assume this payslip will state clearly what her GROSS Hourly Rate is, and if there are any premiums for working nights, Sundays and Bank Holidays. Although I am a bit confused as it does not appear to have been clarified whether or not your daughter is paid locally into a local Bank Account, or in the UK in a UK Bank Account. If this has been mentioned, I apologise for missing it.
But using the calculator in the above link, if your daughter receives a Payslip which I assume she does, she can then work out what her NET Income should be if her payslip shows her WEEKLY or MONTHLY Gross pay and if she knows her Income Tax Code. I would also assume that if deductions are made at source for accomodation, food, Uniform (Does she have to pay for her uniform?) and other 'out of pocket' expenses, then these will be also be shown on her payslip. I believe it is illegal to deduct money from your salary without stating why that money has been deducted and for how much.
I think many of us are actually gastaflabbed by the fact that she is paid only .80p per hour. We are not disputing that, at least I do not think we are, but it would help maybe if, withouit going into too many personal details, she could list what her GROSS hourly rate is and what other items are deducted at source from her Gross Pay. I assume she does not contribute towards a Pension Scheme?
