I did challenge them about the tax and they then told me I had to complete a P46, in order for them to obtain a correct tax code for me and get me off BR.

I had given them a P45 from my previous temp role which had had a BR tax code with it (because I had one and because I thought P45s were preferable over P46s!) but I hadn’t noticed the deduction as much because that role was weekly paid. For the last seven years I have also worked on and off for a nurse ‘bank’ for which I have a proper tax code – I don’t see why I can’t pass that on to this current employer, but apparently each new job needs a new tax code!

(I’ve only been working nineteen years, like!)

I know for a fact my name is mud with the inland revenue with all my temp roles because they as much as said they’re fed up with giving me rebates!

I think there are two things going on here, firstly a comparison of weekly and monthly, and secondly the tax your employer has taken off you.

First thing is to note is that a month is not exactly 4 weeks. 4 weeks would be 28 days, not 30 or 31 – so the monthly value is more than 4 times the weekly value. In fact, the calculator divides the annual figures by 12 to give the monthly figures, and by 52 for the weekly figures. So that’s why 4 times £315 is not £1,365

Secondly, it seems to me that you have been charged too much tax. If you are new to the job, they may have used “emergency tax”, where they don’t know your tax code. Without your tax code, they can’t give you your personal tax-free allowance, so they have taxed all of your income. I’m sure they will clarify this with you – most employers will correct this for your next payslip, and may even refund you the overcharged amount (so next month might be more than you expect!).

I hope this helps, and as always your employer should be able to explain your payslip to you!

I work a temporary job for £10.50 per hour for 30 hours a week with no sick pay and holiday pay pro rata. I got a monthly pay slip this week based on 4 weeks, and my gross pay was £1181.25 because I had to drop one day, so for that week I was paid £236.25. They deducted £314.06, £77.66 for NI and £236.40. I walked away with a minty £867.19 which I’m not at all happy with. Was that 20% BR tax?

But for four weeks at £315 per week, which is correct, I should get £1260 gross – not £1365 as you suggest, surely? So have they overcharged my NI? I’ve queried it with them, quoting the figures I got from your site, but now I’m wondering because your monthly figures seem way off. What else are you taking into consideration there?
