MANY households' finances are feeling particularly stretched as Christmas approaches - but there may be some money you haven't yet claimed which you're entitled to.

HM Revenue and Customs (HMRC) is reminding taxpayers how it can help boost their finances.

Mel Stride, financial secretary to the Treasury says: "The tax HMRC collects funds our vital public services, and also provides financial support to taxpayers and those most in need through programmes delivered by HMRC."

Ways in which people can boost their finances include:

1. If you are married or in a civil partnership you can claim up to £238 a year in Marriage Allowance. It is quick and easy to apply online, and can be claimed at any point in the tax year, and you will still receive the full entitlement. Apply at www.gov.uk/apply-marriage-allowance.

2. Are you on a low income and find it difficult to save money? Help to Save rewards savers with an extra 50p for every £1 saved, meaning over four years a maximum saving of £2,400 would result in an overall bonus of £1,200. To find out more visit www.gov.uk/get-help-savings-low-income.

3. Tax-free childcare is available for parents or guardians with children aged under 12 or aged under 17 if disabled. To check if you're eligible visit www.gov.uk/tax-free-childcare.

4. Nurses, hairdressers, construction workers and millions of other employees can claim tax relief on work-related expenses - money they've spent on items like work uniform and clothing, tools, business travel, professional fees and subscriptions. A simple check if you can claim tool is available at www.gov.uk/tax-relief-for-employees.
