"PAYE and NI have to be paid over to the government monthly in most cases, so any increase here impacts on a business' cash flow as well as hitting the overall profit."
Thanks for that info. It looks to me to be a bad idea, though unless you work in the finance department (or run a small business) it is invisible to most employees.
I assume it will force any public bodies (NHS, Schools, Universities, Police, Ambulance, Fire Service, Councils, etc) to also pay that portion over, leaving less funds for services, books, medicines, etc (when you consider they make up a massive group within the employed population).
Not sure how it makes much difference on being "tax deductible for the business" as they still have to pay up on time (or face penalties, no doubt!) and many firms are struggling at present to keep going.
Someone on a BBC radio breakfast show was saying that there is very little 'wriggle room' to increase prices to cover for extra costs, and meanwhile business rates are shooting up in many areas, and in some places whole streets of shops are expecting to go out of business as they cannot afford 50K in rates.
