 This can be overcome by becoming a limited company however the paperwork is more extensive; limited companies are able to do this because corporation tax rates are much lower than income tax rates.Business which make more than £60,000 have to register for a VAT number they also need to charge their customers VAT, you also need to fill in the relevant VAT returns and send VAT payments to HM Revenue & Customs.VAT is paid on its purchases this is called input tax they also charge tax on sales this is called output tax; if a business gains more output tax from what it pays in input then it must pay the difference, if the business receives more input than output then HMRC will pay the difference.
