Why HMRC Might Contact You if You Earn Over £23,000

HMRC correspondence often arises from discrepancies between your declared income and their records. Several factors can trigger this contact:

• Incorrect Tax Code: A wrongly assigned tax code, whether resulting in overpayment or underpayment of Income Tax, will often prompt HMRC to contact you for clarification and adjustment. This is a common reason for letters, particularly after changes to employment or personal circumstances. Double-check your P45 and P60 for accuracy.

• Missing Tax Returns: For incomes above the personal allowance threshold, submitting your Self Assessment tax return on time is mandatory. Failure to do so is a serious offense, resulting in penalties and potentially further investigation. Remember the Self Assessment deadline – usually 31 January following the tax year.

• Underdeclared Income: If HMRC believes you haven't accurately declared all your income streams – including rental income, freelance earnings, dividends, capital gains, or other sources – they will investigate and contact you for further information. Ensure complete and accurate reporting of all income sources.

• Changes in Circumstances: Significant life events such as marriage, divorce, starting a business, or a change in employment status require updating your tax information with HMRC. Failure to notify them of these changes can lead to correspondence and potential penalties. Notify HMRC of any relevant changes promptly using their online services.

• Random Checks: HMRC conducts routine audits and checks to maintain tax compliance across various income brackets. This is a standard practice and doesn't necessarily indicate an issue, but requires a prompt and thorough response.

Understanding Different Types of HMRC Letters

HMRC uses various types of communication, each carrying different implications:

• Routine Enquiries: These letters often request clarification on specific income sources or expenses claimed. Responding promptly and thoroughly, providing supporting documentation, is crucial to resolve the enquiry quickly.

• Tax Adjustments: These letters outline proposed changes to your tax liability. This could be due to an underpayment (requiring further payment) or an overpayment (resulting in a refund). Carefully review the calculations provided and contact HMRC if you disagree with their assessment.

• Formal Investigation Letters: These indicate a more serious investigation into your tax affairs. This requires immediate action. Seek professional tax advice from a qualified accountant or tax advisor to guide you through the process.

• Penalty Notices: These letters detail penalties for late submissions or inaccuracies in your tax return. Understanding the reason for the penalty is important, as you may be able to mitigate further issues by addressing the underlying cause.

How to Respond to HMRC Correspondence

Effective communication with HMRC is paramount:

• Read the Letter Carefully: Thoroughly understand the specific query or issue outlined in the letter. Note all deadlines and reference numbers.

• Gather Supporting Documentation: Collect all relevant documentation, such as payslips, invoices, bank statements, receipts, and any other financial records that support your income and expense claims.

• Respond Promptly: Always adhere to the deadlines specified in the letter. Delays can lead to further penalties and complications. Use HMRC's online services where possible for faster processing.

• Be Accurate and Clear: Provide concise and accurate information in your response. Avoid ambiguity and ensure all supporting documentation is clear and easily understandable.

• Seek Professional Help: If the letter is complex or you're unsure how to respond, consult a qualified accountant or tax advisor. Professional guidance can save you time, money, and potential penalties.

Common Mistakes to Avoid

Several mistakes can complicate your interaction with HMRC:

• Ignoring the Letter: This is the worst possible action. Ignoring HMRC correspondence will almost certainly lead to penalties, further investigation, and potential legal action.

• Providing Inaccurate Information: Misrepresenting facts will severely damage your credibility and could result in significant penalties.

• Missing Deadlines: Failure to respond within the given timeframe will lead to penalties and may escalate the situation.

• Not Keeping Records: Maintain meticulous records of your income and expenses. This is vital for efficient communication with HMRC and for defending your tax position if necessary.
