You must file a Self-Assessment if you are:

  • Self-employed or a sole trader
  • A company director receiving dividends or salary
  • A landlord with UK rental income
  • Earning income from abroad while living in the UK
  • A non-resident earning UK-based income
    HMRC also requires Self-Assessment for certain types of investments or capital gains.
  • 31 October (paper return)
  • 31 January (online return)
  • 31 January – Payment of tax due
    Missing these deadlines may result in penalties and interest from HMRC.

HMRC will impose penalties:

  • £100 late filing fine (immediately after deadline)
  • Additional daily penalties after 3 months
  • Interest on unpaid tax
    We help you avoid these penalties by ensuring your returns are submitted correctly and on time.

Yes, if you earn income from UK sources (e.g. property rent, dividends, business income), you may need to file a Non-Resident Self-Assessment. Markup Valley specializes in assisting non-residents and overseas clients with UK tax filing.

Typically, we require:

  • Proof of income (invoices, payslips, P60/P45, dividend vouchers)
  • Business expenses (if self-employed)
  • Bank statements
  • Property or rental income records
  • UTR number (if registered with HMRC)
    Don’t worry — our team will guide you on exactly what to provide.

We offer both. Along with tax filing, we provide strategic tax advice to help minimize your tax liability, structure your income efficiently, and stay compliant with evolving HMRC rules.
