The 31st of January is a crucial date for anyone required to complete a HMRC Self-Assessment tax return. If you are self-employed, a company director, or have additional income outside PAYE, this deadline applies to you. Missing it can result in penalties, interest charges, and unnecessary stress.

For individuals and small businesses across West London, including Ealing, Acton, Chiswick, Hanwell and other areas, ensuring your tax return is accurate and submitted on time is essential. HMRC requires all income to be declared correctly, allowable expenses to be properly claimed, and any tax owed to be paid by the deadline. Even a small error can trigger enquiries or fines.

Late submission automatically attracts a £100 penalty, even if there is no tax to pay. Further daily penalties apply after three months, with additional charges after six and twelve months. On top of this, late payment of tax results in interest being added by HMRC.

We ensure you are claiming all allowable expenses, meeting HMRC guidelines, and avoiding unnecessary penalties.
