Do I need to provide my employees with any documents following the year end process?

Yes, you need to provide them with a P60.

Once you’ve completed your year end payroll process, you need to provide all your employees with a P60. This needs to happen by 31^st May. The P60 summarises the employee’s total pay and deductions for that year. Some of your employees may also require a Plld form, which outlines any employee benefits and expenses. If so, this should be provided by 6^th July.
