On 19 January HMRC told Gemma that she was owed a refund of £8,194.96 for the tax year 2024-25.
But within days she said an official contacted her to say that figure was incorrect and that the refund would need to be recalculated using the information on her P60, external – a document that shows the tax paid on your salary in the financial year.
“When I rang up in October, I gave them my P60 figures and they could have just calculated the refund, and given it to me in October,” she said.
After the recalculation HMRC told her she was actually due a refund of £2,863.04, which she received at the end of January.
“My message is make sure you check your tax code,” said Gemma, who wants to make sure other people do not end up overpaying thousands of pounds.
“Make sure it’s right because if it’s happened to me I can guarantee it’s happening to more people.”
