Although the financial impact of this allowance is relatively low, it is surprising that there has not been more uptake of the Marriage Allowance since its inception 6 April 2015. In fact, taxpayers that qualify can still backdate a claim for 2015-16 as well as make a claim for the current tax year, 2016-17.
Marriage Allowance lets you transfer £1,100 of your Personal Allowance to your husband, wife or civil partner – if they earn more than you. This reduces their tax by up to £220 in the tax year. To benefit as a couple, the lower earner must have an income of £11,000 or less.
If you were eligible for Marriage Allowance in the 2015-2016 tax year, you can backdate your claim to 6 April 2015 and reduce the tax paid by up to £432.
