Statutory Maternity Pay and Leave: employer guide
Refuse pay form SMP1
You can refuse Statutory Maternity Pay (SMP) if the employee does not qualify. They may be able to get Maternity Allowance instead.
To refuse it, give the employee the SMP1 form within 7 days of your decision. They must get this form within 28 days of their request for Statutory Maternity Pay or the birth (whichever is earlier).
