I am in the middle of doing 2years worth of tax returns (oops) and after much confusion etc. I managed to find out the correct code from the tax office over the phone. Pity the rest wasn't as straight forward....
phone the HMRC / inland revenue and ask them. 647L is the standard code for those under 65, but if you have taxable allowances like a company vehicle or have underpaid tax in a previous year, or more than one job or source of income, your code could be different
look for the employees helpline. it's handy if you phone when you have a recent payslip to hand as they will ask for your employers reference number, NI number etc, which should all be on your payslip
The only way to be sure that you have been issued with the correct PAYE Coding Notice is to have details of your benefits in kind/prior year tax underpayment adjustments etc to hand and do the calculation yourself. Invariably the Tax Office get it wrong so they would be my last port of call when trying to find out what my code should be.
unless there is a good reason why you aren't on 647L
do you have a company vehicle, or other source of income? what was your tax code the last couple of years? have you underpaid tax previously? you can underpay tax just by having the wrong tax code or not giving the right P45/P46 details when changing jobs
That sounds about right. This means your private medical insurance costs your company £710 which IIRC is about what my old lot used to pay for Bupa. You just pay the tax on this benefit, be it 20% or 40% depending on what you earn.
For years whilst at my old company and having a Seat Cupra R as a company Car and Private medical my code was 288K which is a negative code
This basically meant that before i earnt a penny on Jan 1st, i already owed them 40% of £2880
Now i only have an old pickup truck for work use only my code is back to 647L and i'm rich again
