Could You Be Due An HMRC Refund? A Payslip Check Could Reveal Thousands

Common Reasons for HMRC Underpayments and Missed Refunds

Several factors can lead to unintentional overpayment of tax and missed opportunities for an HMRC refund. Understanding these common reasons is the first step in identifying potential discrepancies on your payslips.

Tax Code Errors

Incorrect tax codes are a frequent cause of overpaid tax. Your tax code determines how much income tax is deducted from your salary. An incorrect code can result in too much tax being taken, leading to a significant HMRC refund.

Examples of common tax code errors: Incorrect digits, missing letters, codes not updated after life changes (marriage, children).
How to identify them on payslips: Look for your tax code clearly stated on each payslip. Compare it to the code HMRC issued to you. If you're unsure, contact HMRC directly for clarification.
Further information:

National Insurance Contributions (NIC) Overpayments

Overpaying National Insurance Contributions is another common scenario resulting in a potential HMRC refund. Various circumstances can lead to this.

Scenarios leading to NIC overpayment: Errors in your employment details, incorrect calculation of NICs based on your earnings, changes in employment status not properly reflected.
Ways to verify on payslips: Check the amount deducted for NICs on each payslip and compare it to your earnings. Look for any inconsistencies over time.
Relevant legislation/HMRC guidance:

Salary Sacrifice Schemes

Salary sacrifice schemes, where you exchange part of your salary for a non-cash benefit (e.g., pension contributions), can sometimes lead to errors in tax and NIC calculations.

Examples of potential errors: Incorrect application of tax relief, discrepancies between the sacrificed amount and the benefit received.
How to check payslips for discrepancies: Carefully compare your gross pay, net pay, and the deductions for the salary sacrifice scheme on your payslips. Look for any inconsistencies.

Marriage Allowance and Other Tax Reliefs

Many taxpayers are unaware of or don't claim tax reliefs they're entitled to, including the marriage allowance. This can lead to unnecessary tax payments.

Eligibility criteria for marriage allowance and other relevant reliefs: Check HMRC's website for detailed eligibility criteria for various tax reliefs.
Where to find this information on payslips: Your payslip may not directly show if you’re receiving these reliefs, but you can use your payslip data to check if you’re eligible.
