The Government has fulfilled its pledge to recognise marriage in the tax system by opening registration for its Married Couples allowance on 20 February. Full story: http://ow.ly/Juhoc
The new Married Couples allowance (not to be confused with the Married Couples allowance for those born before 6/4/1935) essentially allows for a spouse who is earning less than £10,600, so is not paying any tax, to transfer up to £1,060 of their remaining personal allowance to their partner. The big catch is, however, that the partner it is being transferred to must be a basic rate tax payer i.e. earning less than £41,865 (being the £31,865 basic rate limit plus their own personal allowance of £10,000).
