Millions miss out on £23bn of unclaimed benefits...

If you're married or in a civil partnership, you may be entitled to a £1,260 annual tax break called 'Marriage Tax Allowance' – something around two million eligible couples currently miss out on.
Where you're eligible, you only need to apply once (applying is really easy), as you automatically get the tax break each year going forward. You can also get a rebate by claiming for previous years too.
