From today millions of people will begin to receive their first annual tax statement in the post, a document that sets out exactly how much they pay in to the Exchequer and how that money is spent.
If you're one of the five million people who was informed they had overpaid or underpaid tax in the last financial year, you may well find another letter is on its way with a further revised calculation from HM Revenue and Customs (HMRC).
Up to 300,000 homeowners who bought a property in a "disadvantaged" area over the past decade could reclaim up to £1,500 in stamp duty, MoneySavingExpert.com can reveal. But the deadline to claim is 5 May so take urgent action.
If you're filing a self-assessment tax form before 31 January deadline, watch out for websites that'll charge you up to £1,000 when you can do it yourself for free.
