To get SMP you must have been:
Employed by your employer into the qualifying week which is the 15th week before the week your baby is due.
Employed by the same employer without a break for at least 26 weeks into the 15th week before the week your baby is due. Part weeks count as full weeks.
Earning before tax an average of �84.00 a week. This is called the Lower Earnings Limit for National Insurance Contributions (NI) and is the amount you have to earn to qualify for benefits. You have to earn more than this amount before you actually start paying NI.
If YES to all, claim SMP.
