5 Critical HMRC Warnings For Christmas Workers In 2025: Why You Must Check Your Payslip Now

Contents
The festive season of 2025 brings a surge in temporary and seasonal employment across the UK, but HM Revenue and Customs (HMRC) has issued an urgent and critical warning to every single worker: "Check Your Pay." This is not a general reminder; it’s a specific alert for anyone taking on a Christmas job in retail, logistics, hospitality, or any other seasonal sector, urging them to scrutinise their December payslips immediately to avoid serious financial pitfalls. The message is clear: mistakes in pay, tax deductions, and employment rights compliance are rampant during this busy period, and the responsibility to spot them falls on the worker. This year, the HMRC warning is particularly focused on preventing underpayment and correcting common PAYE errors that arise from the practice of paying staff early before the Christmas break. With millions of people, including students and those seeking extra cash, entering the temporary workforce, understanding these five key risks is essential to ensure your hard-earned festive wages are correct and compliant with the law.

The 5 Most Critical HMRC Warnings for 2025 Seasonal Staff

HMRC’s "Check Your Pay" campaign is designed to safeguard the financial well-being of temporary workers who are often the most vulnerable to payroll errors and employment breaches. The five main areas of concern highlight where seasonal workers are most likely to be short-changed or face tax complications.

1. The National Minimum Wage (NMW) and National Living Wage (NLW) Trap

A core element of the HMRC alert is ensuring all workers are paid at least the legally mandated National Minimum Wage (NMW) or National Living Wage (NLW). Temporary staff, especially younger workers or those hired through agencies, are statistically more likely to be paid incorrectly. * Know Your Rate: The NLW is the minimum wage rate for workers aged 23 and over. Different, lower rates apply for those aged 21-22, 18-20, and under 18. * The 'Deduction' Trick: Some unscrupulous employers attempt to reduce pay below the minimum wage by making illegal deductions for things like uniforms, training costs, or transport. HMRC warns that these deductions, if they take the hourly pay below the legal threshold, are non-compliant. * Unpaid Working Time: This includes time spent on mandatory training, security checks, or staying late to close up. All hours worked must be paid, and failure to do so can breach NMW rules.

Action Point: Calculate your exact hourly rate after any deductions are taken. If it falls below the statutory minimum for your age bracket, you must raise the issue with your employer or report it to HMRC directly.

2. The Early Christmas Payday PAYE Pitfall

The practice of employers paying December wages early—often on the 20th or 21st of the month instead of the usual end-of-month date—creates a significant compliance risk for Pay As You Earn (PAYE) reporting. * The Reporting Rule: HMRC explicitly reminds employers that when paying early for Christmas, they must still report the *normal* or *contractual* payday on their Full Payment Submission (FPS) via Real Time Information (RTI). * The Worker Impact: If the employer reports the *actual* early payment date instead of the contractual date, it can cause the tax year to show two payments in the same month, or even two payments in one tax year where there should only be one, potentially leading to an incorrect tax code being applied in the new year or a temporary over-taxation. * Double Pay in December: For employees who receive a payment for the remainder of December and an early January payment in the same month, this can push them into a higher tax bracket for that period, resulting in higher deductions. While this is often corrected automatically later, it can cause immediate financial strain.

3. The Wrong Tax Code and Emergency Tax

Seasonal workers, especially students or those with a main job, are highly susceptible to being placed on the wrong tax code, often resulting in them paying more tax than necessary. * Secondary Jobs and Tax Codes: If a Christmas job is a second job, the worker will likely be on a 'BR' (Basic Rate) tax code, meaning all income from that job is taxed at 20% with no Personal Allowance applied. This is usually correct. * The Emergency Tax Trap: If a worker doesn't provide a P45 from a previous job, or if their new employer doesn't process their details correctly, they can be put on an emergency tax code (like '0T' or 'W1/M1'). This can lead to significant over-deduction of tax. * Students and the Personal Allowance: Many students or temporary workers earn less than the annual Personal Allowance (the amount you can earn tax-free, which is £12,570 for the 2025/2026 tax year). If their code is wrong, they may pay tax unnecessarily and then have to claim it back.

Action Point: Check your payslip for your tax code. If you believe it's wrong (e.g., if you are a student and this is your only job, your code should typically be 1257L), contact HMRC immediately via your Personal Tax Account or phone to get it corrected.

4. The Looming Threat of Tax Rebate and Self Assessment Scams

The festive period, and the subsequent January tax deadline, is a peak time for sophisticated phishing and tax fraud attempts. HMRC warns that seasonal workers are prime targets for these scams. * Phishing Emails and Texts: Fraudsters impersonate HMRC, sending emails or texts about a "tax rebate" or "overpayment" that requires the worker to click a link and enter personal or bank details to receive the money. HMRC will never notify you of a rebate via text or email. * Threatening Calls: Scammers may call, threatening immediate arrest or legal action due to an unpaid tax bill, demanding payment via unusual methods like gift cards or bank transfer. HMRC will never use threatening language or demand immediate payment in this manner. * Fraudulent Tax Credit Schemes (Targeting Employers): HMRC has also issued a warning to employers and temporary work agencies about organisations offering fraudulent schemes that claim to reduce employment costs through 'tax credits.' While this targets the employer, it can indirectly affect the worker's compliance and pay record.

Action Point: Be extremely vigilant. If you receive a communication claiming to be from HMRC, do not click links or provide information. Check the sender's email address or phone number against the official HMRC contact details on the GOV.UK website. If in doubt, assume it’s a scam and report it.

5. The Holiday Pay and Entitlements Oversight

While the HMRC primary warning focuses on pay and tax, seasonal workers often overlook their right to paid annual leave, known as "holiday pay." * Accrued Leave: Even on temporary or fixed-term contracts, workers accrue holiday entitlement from day one. For every hour worked, a specific amount of paid leave is built up. * Payment in Lieu: If the contract ends before the worker can take the accrued holiday, the employer must pay the worker for the untaken leave—this is called "payment in lieu of holiday." * Payslip Check: Ensure your final payslip clearly shows any payment in lieu of holiday pay, as this is a common area where temporary workers are underpaid.

What to Do If You Spot an Error on Your Christmas Payslip

Discovering an error, whether it’s a National Minimum Wage breach or an incorrect tax deduction, requires swift, methodical action. Do not panic, but do not delay.
  1. Gather Evidence: Keep all your payslips, your contract of employment, and any records of hours you have worked (including start and finish times).
  2. Contact Your Employer: The first step is always to raise the issue with your employer or their payroll department. Payroll errors are common, and most can be resolved internally quickly.
  3. Contact HMRC Directly: If your employer refuses to correct a tax code or PAYE error, or if you are concerned about a potential tax scam, you must contact HMRC. You can use your Personal Tax Account (PTA) online for the quickest resolution of tax code issues.
  4. Report Minimum Wage Breaches: If you believe you have been paid less than the National Minimum Wage, you can report your employer to HMRC anonymously. HMRC has specialist teams that investigate NMW breaches.
The HMRC warning to Christmas workers in 2025 is a timely reminder that vigilance is the best defence against payroll mistakes and fraud. By checking your payslip against the key risks of NMW, early pay reporting, tax codes, and scams, you can secure your festive earnings and start the new year on a sound financial footing.
