One in ten small businesses is being investigated by tax officials. Tax investigations may be compliance enquiry or visits, or both. Tax officials may visit you to check your accounting records, including VAT, payroll, and accounts. They have access to your place of business and the parts of your home that are used for business. Written notice will be given in advance. They can ask for a check on the site itself, as well as the business assets and business documents that are kept there. You may consider hiring an accountant to attend a compliance visit meeting.
