What Happens If You Don't File a Tax Return​?

Filing a tax return in the UK is a key obligation for individuals and businesses with certain income streams. Tax returns are essential for HM Revenue & Customs (HMRC) to assess and collect income tax. While most people have their tax deducted automatically from their wages or pensions through the PAYE (Pay As You Earn) system, others who receive additional income must declare it to the government. But what happens if you don't file a tax return on time, or at all? This article addresses the consequences, legal implications, penalties, and the steps taxpayers can take to rectify late submissions.
