What is self assessment?
Self-assessment is the system HMRC uses to collect income tax from individuals whose earnings aren’t taxed through PAYE (Pay As You Earn). If you’re self-employed, a company director, or earn additional income from property, dividends, or investments, you may need to submit a self-assessment tax return. Filing your return correctly and on time is crucial to avoid penalties and ensure you're only paying what you owe.
At dns accountants, our self assessment services help you navigate the tax return process with ease. We provide expert guidance to ensure your return is accurate, compliant, and submitted on time—so you never have to worry about HMRC deadlines.
