Your employer must provide you with a payslip.
They do not have to do this if you are:
in the police service
a merchant seaman
a master or crew member working in share fishing (paid by a share in the profits or gross earnings of a fishing vessel)
Your payslips can be used as proof of your earnings, tax paid and any pension contributions. Employers can choose whether they provide printed or electronic (online) payslips.
Payslips must be provided on or before payday.
What should be on your payslip
Your payslip must show:
your earnings before and after any deductions
the amount of any deductions that may change each time you are paid, for example tax and National Insurance
the number of hours you worked, if your pay varies depending on time worked
Employers must also explain any deductions fixed in amount, for example repayment of a season ticket loan. They can choose to do this either on a payslip, or in a separate written statement.
This separate statement must be sent out before the first payslip. Employers must update this every year.
Additional information on payslips can be found on GOV.UK's website.
