What it means for your Southampton company
Southampton's economy is shaped by the port, shipping, marine engineering and the mapping and data industries. Many limited companies serve the maritime sector or contract to larger employers, so IR35, travel and subsistence on offshore or away work, and VAT on international services are common questions. Cruise-related seasonality also affects hospitality businesses.
