The Low Incomes Tax Reform Group (LITRG) has issued a guide on what people should do if they receive a tax calculation letter from HMRC.
Around 45,000 taxpayers are receiving letters from HMRC explaining they have paid the wrong amount of tax, with 6 million expected to receive notifications by Christmas.
The letters refer to the tax years 2008-09 and 2009-10 and it is possible that people have both overpaid and underpaid tax in the two years. These people could receive two letters in the same envelope from the HMRC. The payments could cancel each other out.
The tax authority also confirmed that it would not charge interest on underpayments under £2,000, according to a BBC report.
