When a new employee joins a UK company, he has to present to his new employer his P45 form obtained from his previous employer, or if doesn’t have one he will have to complete a starter checklist form, available to download on the HMRC’s website. These forms are sent to the HMRC in order they can trace the employment and allocate Tax codes & NIC codes to the relevant persons.

This tax code will have to be made available as soon as possible to the employer in order the PAYE deduction on the payroll is calculated accurately. If this code is not available yet or not transmitted to the employer, the emergency tax code & tax rate will apply and regularization will be made only after the end of the UK tax year, being 5th of April each year.


(see « Focus On SSP » SEDI’s form for more details)

As an employer, you have to maintain a minimum regulated salary when your employee is on a sick leave. It is highly recommended to secure even a bit more with a complementary Company sick paid and/or income protection for example, than the minimum regulated salary if you wish your employee is able to survive during his sick leave.

The 2018 weekly rate of SSP is £92.05 up to 28 weeks.

First 3 days being called « waiting days », are paid at the discretion of the employer. The SSP Policy in the company has to be very much disclosed either in the employment contract or in the company handbook when there is one. It will be up to the employer to calculate the « qualifying days » applicable for the SSP calculation.

A sick note is complusory after 7 days.
