YES! If you’re determined, well-informed, and have plenty of patience, you can attempt to claim a tax refund yourself through HMRC. But to do so successfully, you’ll need to know exactly which aspects of your tax records to review for each of the past four tax years. You’ll also need to identify the specific allowances you were eligible to claim, spot any errors made by HMRC or your employer, and most importantly, know precisely what questions to ask HMRC.

It also assumes you’re familiar enough with Pay As You Earn (PAYE) rules to recognise when HMRC’s answers are actually correct, which unfortunately isn’t always guaranteed. According to a survey by the Low Income Tax Reform Group, HMRC’s call centres gave incorrect answers in up to 80% of complex cases.

If you do secure a refund yourself, you’ll need to be confident the amount is correct. If HMRC overpays you, they’ll certainly want the excess back in the future, even if it’s already spent. But the greater risk is that they underpay you, leaving you with less than you were truly owed. And let’s be clear: if you didn’t ask the right questions or present the right information, that shortfall is usually on you, not HMRC.

Another important consideration rarely mentioned by “DIY” tax guides is that when you ask HMRC to review your records, they may discover you owe them money. Sometimes they’re right but we regularly see cases where the amount they demand is significantly inflated. In fact, over half of the underpayment cases we review turn out to be wrong. Without expert help, you may have little choice but to pay the amount they demand, which they can simply deduct from your future wages.

Remember we will always discuss an underpayment case with you before HMRC, Let us find it rather than them!
