South Oxfordshire ranks 491 of the 1105 areas we serve by number of micro businesses, and its micro share of 90% is in line with the 89% average across them. In construction (1,050 micro businesses in South Oxfordshire), Construction Industry Scheme deductions, retentions and stage payments can distort profit, so we reconcile your CIS statements before the accounts are prepared. In wholesale and retail (795 micro businesses in South Oxfordshire), closing stock and the VAT treatment of different product lines are the usual pressure points, so we value stock carefully and check your VAT records.
