 Another reason many UK businesses outsource is because of the ever increasing complexity of finance legislation.Annual changes in tax codes, PAYE and National Insurance bands as well as more and more statutory payments and deductions having to go through the finance often mean there is a lot to keep abreast of in order to maintain compliance with the current legislation.Unlike in the USA, fines and penalties for compliance issues remain the responsibility of an employer, even if they have outsourced their administration.
