My P45 is apparantly being sent out in the post, but I still don't understand why I wasn't taxed for 2 weeks and then I was taxed again??
Did you earn a lot less in those two weeks than the newest week as that might explain it.
The way it was explained to me is :-
Tax Code - 605L This means you can earn £6050 a year before paying tax, however tax each pay packet is based on a percentage of that figure.
£6050/12 = £504.17 in the first pay packet before you would be taxed if paid monthly and
£6050/52 = £116.35 in the first pay packet before you would be taxed if paid weekly.
So say you earn £200 in a week or £850 in a month you would obviously pay tax that week/month, then the next pay packets tax would be calculated based on your new non-taxable allowance which would be
Weekly - £6050 - £200 / 51 = £114.70 is your earning limit week two before you would be taxed.
Monthly - £6050 - £850 / 11 = £472.73 is your earning limit in month two before you would be taxed.
If in week/month two you then earned less than the the £114 or £472 you wouldnt be taxed that month.
This is the reason everybody pays tax even students, if they earn a certain amount in a pay period, but if over the course of the whole year you earn under the £6050 (or whatever your tax code allows, you would get the tax back).
