Self Assessment Tax Return

Filing a self assessment tax return can be stressful, but ensuring accuracy is crucial to avoid penalties and overpaying tax. Our expert self assessment services help local business owners, self-employed individuals, and company directors file correctly, stay compliant with HMRC, and maximise tax efficiency.

What is a Self Assessment Tax Return and Who Needs to File One 

A self assessment tax return (SA100) is a report submitted to HMRC detailing your income, expenses, and tax owed. If you receive income outside of PAYE employment, you may be legally required to file one.

You must submit a self assessment tax return if you:

  • Are self-employed or a sole trader
  • Are a company director receiving dividends
  • Earn income from property, investments, or foreign sources
  • Receive freelance or contract income outside of PAYE
  • Earn over £100,000 per year, even from employment

Filing late or incorrectly can lead to penalties and overpaid tax, so working with an expert ensures accuracy and compliance.

Missing HMRC’s self assessment deadlines can result in automatic fines, so it is important to file on time.

Key Self Assessment Deadlines

  • Paper tax return deadline: 31st October
  • Online tax return deadline: 31st January
  • Tax payment deadline: 31st January

What Happens if You Miss the Deadline
