UK business owners pay tax differently depending on structure. Sole traders pay Income Tax on business profits through Self Assessment, while individual partners pay Income Tax on their shares of partnership profits. Rates, allowances, deadlines, and reliefs differ between the two systems, and the right structure depends on profit levels, growth plans, and how money is drawn from the business.
UK contractors face stricter Construction Industry Scheme rules after April 2026, with reinstated nil returns and closer HMRC oversight of supply chains. Common issues are worker misclassification, incorrect deductions, missed deadlines, and verification errors. Timely filing, proper verification, and accurate records are key to avoiding penalties.
The Construction Industry Scheme lets contractors claim eligible expenses, such as materials, tools, clothing, travel, phone, insurance, and fees, that can lower taxable profit and boost refunds. Proper records, accurate claims, and correct CIS deductions ensure compliant tax returns and eligible costs aren’t missed.
