Online marketplaces will be required to ensure VAT numbers displayed for business on their website are valid, and to display a valid VAT number when provided with one by a business operating on their platform. A split payment model is being considered to reduce online VAT fraud and improve collection. A call for evidence will explore what more digital platforms could do more to ensure their leaders are compliant with tax rules generally.
