Operating in the marine and fishing industries often means facing unique pressures. These range from navigating complex licensing and fuel duty claims to managing seasonal income and staying compliant with ever-changing regulations relating to seafarer tax.
Our team of marine accountants specialise in understanding not only the issues and compliance requirements, but the strengths of the industry.
At TC Group, we go beyond the basics. ‘Advice’ isn’t just a list of options – it’s about understanding your operation, your goals, and giving you clear, confident guidance to seize opportunities and build long-term stability.
We work with a wide range of marine and fishing clients, including naval architects, offshore contractors, divers, consulting engineers, wild fisheries, and fish farms. We also advise individuals and businesses on specialist areas such as seafarers’ earnings deduction.
Our hands-on experience means we’re well-versed in the specific issues you face, including marine mortgages, quota purchase and sale, shared fishing arrangements, licensing, and more.
