Hi there
the national insurance will be 1% of everything over �91 (Oneeyedvic, you used the LEL not the Earnings Threshold), therfore �18.85. Tax will be �33.67 as Oneeyedvic says, making a total of �52,52, and net pay of �209.98. The emergency code is not 25%, it is the normal single persons code, but it does not take into account the tax free amount available for weeks prior to the commencement of employment. Once the employer obtains a tax code from the Inland Revenue (or if your friend has a P45 from a previous job this tax year), any unused free-pay (for example if your friend had not been working or had been claiming Job Seekers Allowance)will be allocated, and a refund given. The above figures for tax and NI will be the ongoing deductions for a single person, with no other benefits in kind or sources of untaxed income.
