According to data from HMRC, an estimated 1.3 million workers are entitled to a tax refund due to overpaid income tax on temporary summer employment. This often arises when individuals do not earn above the personal allowance threshold or are assigned an emergency tax code by their employer, resulting in unnecessary deductions from their wages.
The standard personal allowance for the 2024/25 tax year remains at £12,570. If a person's total earnings for the entire tax year, including any summer job income, fell below this figure, they should not have paid any income tax. However, employers frequently apply a tax code based on assumptions about annual earnings, especially if an employee lacks a P45 from a previous job, leading to tax being deducted even from low earners.
HMRC's automatic refund process is triggered for some individuals in PAYE (Pay As You Earn) schemes whose tax position becomes clear after the tax year ends. Nonetheless, relying solely on this can result in delays, and some refunds may be overlooked. To mitigate this risk, individuals can proactively check their tax situation and claim any overpayment directly.
To initiate a refund inquiry, individuals can access their personal tax account online via the Government Gateway, which provides details of income, tax paid, and tax codes used. Alternatively, those without online access can contact HMRC by phone or post, requiring completion of a P50 form if they are not working and not claiming benefits, or a P810 form for other circumstances.
Eligible claims for overpaid tax can be made for up to four tax years, allowing individuals who had summer jobs in previous years and suspect they overpaid tax to reclaim funds dating back to the 2020/21 tax year. Gathering payslips and P60s from the relevant period will facilitate verification of earnings and tax deductions.
For those concerned about potential overpayments, HMRC's website offers a comprehensive guide on claiming refunds, providing essential information for individuals seeking reimbursement for underpaid income tax.
