Martin Lewis has issued an urgent warning to all households ahead of the start of the new tax year on April 6.
The Money Saving Expert founder said many people could be missing out on thousands of pounds. As part of the cost of living crisis episode of his Money Show Live earlier this month, Mr Lewis explained how tax rules meant people should act now to avoid losing out.
Under tax rules you can only claim back four years, so if you're owed money from the 2017/18 financial year, you should apply now or you will lose the opportunity. During the ITV show, Martin highlighted three "big categories" where many people may be able to claim backdated payments from HMRC.
