Paying and Recovering - SMP/SAP/SPP/ShPP: how much advance funding can an employer apply for
Employers must only apply for what they are entitled to recover.
For example if an employer is liable to pay £100 SMP, and has £50 in tax and NICs to pay, they must only apply for £50.
All employers are entitled to recover 92% of the SMP, SPP, ASPP and SAP they pay, if they qualify for SER they are entitled to recover 100% of the SMP, SPP, ASPP and SAP they pay plus an additional amount as compensation for NICs.
