Self Assessment is an essential part of the UK’s tax system, allowing individuals to report income not automatically taxed through the PAYE (Pay As You Earn) system. Whether you’re a freelancer, landlord, small business owner, or even a PAYE employee with additional income, understanding Self Assessment is key to compliance and tax optimisation. This comprehensive guide provides everything you need to know about Self Assessment, from eligibility to expert filing tips. Legacy Accounting is here to simplify your journey.

Who Needs to File a Self-Assessment?

While PAYE employees typically don’t need to file, certain taxpayers must complete a Self Assessment:

Practical Example: If you’re a PAYE employee with freelance earnings exceeding £1,000, you’ll need to file a Self Assessment.

How to Register for Self Assessment

If you’re filing for the first time, you must register with HMRC. Here’s how:

  1. Create a Government Gateway Account: This secure account manages your tax information.
  2. Register for Self Assessment: Complete the registration form online.
  3. Receive Your UTR: HMRC will post your Unique Taxpayer Reference (UTR) within 10 days. This is required for filing.

Key Deadline: Register by 5 October following the end of the tax year when you first earned untaxed income.

Key Deadlines to Remember

Staying on top of deadlines is crucial to avoid penalties:

  • 5 October: Registration deadline for new filers.
  • 31 January: Deadline for filing and paying online tax returns.
  • 31 July: Deadline for the second payment on account, if applicable.

Late filings incur a penalty starting at £100, with additional interest on unpaid taxes. Legacy Accounting ensures timely compliance to avoid these fines.

Documents You’ll Need for Self-Assessment

Efficient filing starts with organised records. Essential documents include:

  • Your UTR and National Insurance Number.
  • Income records (e.g., invoices, payslips, P60/P45).
  • Expense receipts and bank statements.
  • Additional income details, such as dividends or rental earnings.

Tip: Maintain clear and accurate records throughout the year. Legacy Accounting can streamline this process for you.

How to File Your Tax Return

Filing involves reporting all income, expenses, and applicable reliefs. Follow these steps:

  1. Log In: Access your Government Gateway account.
  2. Enter Income Details: Report all earnings, including self-employment and rental income.
  3. Claim Allowable Expenses: Deduct eligible business and property expenses.
  4. Submit and Pay: Verify all information before submission. Pay any tax due by 31 January.

Allowable Expenses: Maximise Your Savings

Claiming allowable expenses reduces your taxable income. Examples include:

  • Travel: Mileage for business trips.
  • Office Costs: Internet, stationery, and phone bills.
  • Professional Fees: Membership subscriptions.
  • Property Costs: Repairs and letting agent fees.

Tip: Keeping detailed expense records ensures you don’t miss out on tax savings.

Common Mistakes to Avoid

High-Income Earners and Self Assessment

If you earn over £100,000, additional obligations apply:

  • Your Personal Allowance decreases by £1 for every £2 of income over £100,000.
  • Accurate reporting is critical for compliance and tax optimisation.

Foreign Income and Self Assessment

Income earned abroad, such as dividends or rental income, must be reported. HMRC’s double taxation agreements may prevent paying tax twice. Legacy Accounting helps navigate these complexities.
