What is Self Assessment?

Self Assessment is the system used by HMRC to collect Income Tax from individuals whose income isn’t taxed automatically, such as business owners, landlords, and those earning through investments. If you fall into any of these categories, you are legally required to file a return.

Based in North West London, Cohen Accountants can assess your situation and handle the full process for you—ensuring compliance, reducing stress, and identifying tax-saving opportunities.

  • You are self-employed or a sole trader
