This is all worked out on a sliding scale so you need to find out what bracket you fall in to, to see what tax level will be applied to your gross salary. There is a set percentage for
national insurance.
If you are an employee, you will have filled in a form stating your marital status, dependants, pension etc.
These will all carry deductions towards your taxable income. When that is worked out, they apply a percentage to the remainder, and that tax is deducted each month from your salary.
If you are unsure what tax bracket you fall into, work out your annual income, in other words your salary times by twelve, or thirteen as is the case, plus overtime, company car etc.
I suggest you go to your company accountant and ask him to calculate this for you.
