The number one question for first time UK contractors going to work in the Netherlands is usually , can I use my UK company. In the same way that the UK has IR35 , Holland has what is called Chain law or the wadi rules ,what this means to a contractor is that if their employed a Dutch company , the material employer /end client can be held liable for all Social security income Tax and VAT , that remains un paid by you.
Naturally this puts a lot of pressure on a professional contractors to conclude a contract to start in Holland without a proper solution, all companies or legal entities providing workers in the Netherlands , must register this activity with the trade register of Dutch Chamber of Commerce , in practice , what it means that , if a company is not sole registered the end client will not pay your invoice.
