If an employee earns £255,00 a week how much in tax is he supposed to pay?

You are allowed to earn £6475 per year tax free

So ...if you earn £255 x 52 weeks in the year = £13260 per year

less the tax free allowance = £6785 which you will get taxed upon.

You pay 10% on the first £2440 = £244 per year
And you pay 20% on the rest = (6785-2440) 4345 x 20% = £869 per year.

Total tax per year = £1113.
Divide by 52 weeks = £21.40 tax per week.

So ...gross pay = £255.00 per week ...weekly tax = £21.40 .....net pay = £233.60 per week

Good Luck!

Although http://www.listentotaxman.com is a good site, it doesn't do in-year calculations. Your previous earnings from 6th April (the start of the tax year) also need to be taken into account, as PAYE is operated on a cumulative basis. The NIC figure should be OK.

it depends on his tax code which is determined by his circumstances and how much tax he has already paid.

I earn that much and £400 pound out of it goes to tax!!! the first month you pay emergency tax so it will be slightly Higher.
