When hmrc can write off arrears and the work of the adjudicators

HMRC has significant powers to write off tax arrears in certain circumstances, though these powers are exercised sparingly and often with the involvement of independent adjudicators. Understanding when write-offs might apply—and how to navigate the process—can be crucial if your business or personal tax affairs have fallen into difficulty.

When Can HMRC Write Off Arrears?

HMRC doesn’t casually forgive unpaid tax. The organisation operates under strict legislative frameworks, primarily the Taxes Management Act 1970 and the Civil Service Code. Write-offs are confined to specific circumstances:

Debts under £10,000 can be written off by HMRC officers if collecting the money would be uneconomical or disproportionate. However, this threshold is treated conservatively, and officers must document their reasoning thoroughly.

Insolvency or death often triggers write-offs. If a taxpayer has genuinely become insolvent with no realistic prospect of recovery, HMRC may accept that pursuit is futile. Similarly, when an estate has insufficient funds to cover all liabilities, tax debts rank behind secured creditors but may be partially or wholly unrecoverable.

Unfair treatment or official error can justify write-offs, particularly where HMRC’s own conduct has materially worsened the taxpayer’s position. This is where adjudicators enter the picture.

The Role of the Tax Adjudicators

The Adjudicator’s Office (part of the Independent Case Examiner scheme) provides an independent review mechanism when HMRC decisions appear unreasonable or when maladministration has occurred. Whilst the Adjudicator cannot force HMRC to write off a debt, they can recommend it and apply considerable moral pressure.

Common grounds for adjudication include:

• Unexplained delays in issuing assessments or pursuing arrears, where limitation periods might otherwise have expired
• Poor communication that prevented a taxpayer from understanding their liability
• Inconsistent treatment compared to other taxpayers in similar circumstances
• Loss of records by HMRC leading to inability to defend assessments properly

The Adjudicator can recommend write-offs up to £100,000 and can award compensation for distress, inconvenience and time spent. Their decisions, whilst non-binding on HMRC, are taken seriously—refusal to accept an Adjudicator’s recommendation requires ministerial-level sign-off.

Practical Steps if You Have Arrears

If you’re facing unpaid tax, don’t ignore it. HMRC has powerful recovery tools: bailiffs, attachment of earnings orders, and director disqualification proceedings (for company directors). Early engagement is always preferable.

First, obtain clarity. Request a detailed statement of your account from HMRC. Verify that all payments have been credited and that assessments are correct. Errors happen—and sometimes interest has been incorrectly calculated.

Consider a Time to Pay arrangement. HMRC is often willing to negotiate instalments if you’re making genuine efforts to clear arrears. These are typically interest-bearing but prevent enforcement action whilst in place.

Explore whether an adjudication might help. If you believe HMRC has acted unreasonably—for instance, by issuing an assessment years late or by failing to acknowledge correspondence—the Adjudicator’s Office can investigate at no cost to you.

Document everything. If pursuing a write-off, gather evidence of hardship, financial statements, and correspondence with HMRC. Be honest about your circumstances.

When Write-Offs Are Unlikely

HMRC will rarely write off arrears simply because paying them is inconvenient or unwelcome. They expect taxpayers to have budgeted for tax liabilities. If you’ve deliberately avoided paying tax or concealed income, write-offs won’t apply. Similarly, if you’ve chosen to spend money on non-essentials whilst leaving tax unpaid, HMRC’s sympathy will be limited.

That said, genuine hardship—redundancy, serious illness, bereavement, or business failure—may justify a more flexible approach, particularly if combined with evidence of HMRC’s procedural failings.

Conclusion

Tax arrears are stressful, but options exist. Understanding when HMRC might write off debts, and how independent adjudicators can challenge unreasonable conduct, means you’re not powerless. The key is engagement: respond to HMRC correspondence, provide accurate information, and seek professional advice early if your position is complicated.
