Several things can affect whether a P45 is generated for an employee.

• A P45 can only be generated once the final pay period is closed and finalised.
• If a payment was made after an employee’s leaving date within the same pay period, this may prevent P45 generation.
• If you update an employee’s leaving date, you may need to reopen and re-finalise the relevant pay period for the change to take effect.
• Please ensure the employee’s tax code and previous employment details are entered correctly in their profile, as this affects P45 creation.

• If you’re having trouble generating a P45, check that the correct tax year and leaving date are set in the system.

  As soon as the employee’s final payslip is finalised, you will be able to generate their P45.

If the 'Leave Date' field is greyed out, this will be due to there being no open payslips in the tax year. You would need to re-open the employee's last payslip in order for this field to be editable.
