HMRC Warning For Over-65s: 3 Critical Tax Traps And Scams To Avoid In 2025/2026

Contents

The financial landscape for UK pensioners has shifted dramatically in the 2025/2026 tax year, and HM Revenue and Customs (HMRC) is issuing urgent warnings to the over-65s demographic. As of today, December 19, 2025, the primary concern revolves around the compounding effect of frozen tax thresholds and the rising State Pension, a combination that is inadvertently pushing thousands of retirees into paying tax for the first time or facing unexpected, significant tax bills. This is not a new tax but a systemic trap that requires immediate attention.

The most alarming alert centres on a potential 'tax trap' that could result in unexpected charges of up to £2,500 for those over 65 who have multiple sources of income, such as a private pension and savings interest, alongside their State Pension. This comprehensive guide breaks down the three most critical financial risks you need to understand right now, alongside the latest fraud warnings from HMRC.

The £2,500 Tax Trap: Why Frozen Thresholds Hit Pensioners Hardest

The core of the current HMRC warning for older taxpayers is the prolonged freeze on the Personal Allowance. The Personal Allowance is the amount of income you can earn each tax year before you start paying Income Tax, and it has been frozen at £12,570 since 2021/22 and is set to remain at this level until 2028.

  • The Critical Threshold: For the 2025/2026 tax year, the full New State Pension is set to increase to approximately £230.25 per week, totalling around £11,973 per year.
  • The Narrow Gap: This leaves a gap of only about £597 between the State Pension and the £12,570 Personal Allowance.
  • The Tax Trigger: Any additional income—be it from a small private pension, occupational pension, or even modest savings interest—that exceeds this small gap will be subject to Income Tax.

This situation creates a 'stealth tax' known as fiscal drag. As the value of State and private pensions increases with inflation, more people are dragged into paying tax, or they are pulled into a higher tax band, even though their real-term spending power has not significantly improved. The unexpected £2,500 charge mentioned in recent alerts refers to the potential cumulative underpayment that can occur over several years for those who have not adjusted their tax affairs.

State Pension Changes and Your Tax Code: The Unexpected Bill Trigger

A second major point of friction for the over-65s is how the State Pension increase affects their tax code, which is the mechanism HMRC uses to collect tax on other forms of income. The State Pension itself is taxable, but it is paid without tax being deducted.

HMRC's standard procedure is to reduce the taxpayer's Personal Allowance by the amount of their State Pension. This reduced allowance is then applied to other income sources, such as a private pension or wages, via a tax code (e.g., 1257L).

What to Check in 2025/2026:

  • Tax Code Review: Since the State Pension is rising significantly, HMRC must adjust millions of tax codes. If the new tax code is incorrect, or if HMRC is unaware of a new income source (like starting a new small part-time job or a new private pension), it can lead to underpayment.
  • The P800 Notice: If you have underpaid tax, HMRC will send you a P800 notice or a Simple Assessment letter. This is the formal way they inform you of a tax bill. If you receive one of these, you must check it carefully.
  • Multiple Income Streams: Pensioners with multiple small income streams—a State Pension, a small private pension, and a few hundred pounds of bank interest—are the most likely to have an incorrect tax code because HMRC's automated systems sometimes struggle to correctly aggregate these varying amounts.

Action Point: You should immediately check your latest tax code notice and compare the State Pension figure listed against the actual amount you are receiving for the 2025/2026 tax year.

Urgent Scam Alert: 5 Ways Fraudsters Are Targeting Over-65s Now

Beyond the complex tax rules, HMRC has issued repeated and urgent warnings about a surge in sophisticated scams designed to steal personal and financial information. Scammers often target older, more vulnerable individuals by exploiting fear of a tax bill or promising a refund.

Since February 2025, HMRC has been alerted to over 4,800 Self Assessment scams alone, urging the public to stay vigilant. Fraudsters are leveraging several key themes:

1. Self Assessment Scams

Even if you have never filed a Self Assessment tax return, scammers may contact you via text, email, or recorded message, claiming you have an outstanding tax liability that must be paid immediately. They use phrases like "urgent tax debt" or "final notice."

2. Phishing Emails and SMS Texts

These messages often claim you are due a tax refund and contain a suspicious link. HMRC will never use text messages or emails to notify you of a tax refund or ask you to click a link to claim one.

3. Threats of Arrest or Legal Action

Scammers often use aggressive phone calls, sometimes using sophisticated 'spoofing' technology to make the call appear genuine. They may threaten arrest, fines, or imprisonment if a fake tax debt is not paid immediately via gift cards, bank transfer, or cryptocurrency.

4. Winter Fuel Payment Scams

Fraudsters are known to target recipients of government benefits. HMRC has specifically warned about scams related to the Winter Fuel Payment, using phishing websites and SMS to try and steal banking details under the guise of an "application" or "confirmation" process.

5. Fake Tax Rebate Calls

A common tactic involves a caller claiming to be from HMRC, stating you are due a large tax rebate, but first, they need your bank details or a small upfront "processing fee." This is a classic identity theft and fraud attempt.

Essential Action Plan: How to Protect Yourself and Your Finances

To navigate the frozen thresholds and protect against fraud, the over-65s should take the following steps immediately:

  • Review Your Tax Code: Log into your Personal Tax Account on the GOV.UK website or call HMRC to confirm your current tax code for 2025/2026 is correct, especially if your State Pension has recently increased or you have new savings income.
  • Report Scams: If you receive a suspicious email, forward it to phishing@hmrc.gov.uk. For suspicious texts, forward them to 60599. Do not click any links or reply.
  • Never Pay with Unusual Methods: HMRC will never demand immediate payment via gift cards, pre-paid debit cards, or cryptocurrency.
  • Use Official Communication: HMRC will typically contact you about tax debts or underpayments via post (a P800 or Simple Assessment letter). If in doubt, hang up and call the official HMRC helpline number, which you can find on the GOV.UK website, not a number provided by the caller.
  • Seek Professional Advice: If you have multiple complex income streams, consider consulting a tax adviser or accountant to ensure your tax affairs are managed efficiently and to avoid the potential £2,500 tax bill.

Staying informed about the latest HMRC rule changes and scam tactics is the best defence against both unexpected tax bills and financial fraud. The current warnings highlight the need for pensioners to be more proactive than ever in managing their tax affairs.
