According to HM Revenue & Customs guidance, you can only claim for a Tax Year in which you were married.
The rules do not consider whether you were married in 2015 or prior to 2015. The rules only consider whether you were married for at least 1 day during any of the 4 years that you can claim for.
If you wish to receive any guidance or advice, please contact HM Revenue & Customs by telephone on 0300 200 3300.
Our UK-based call centre staff are trained to help you make an informed decision. Please note we are unable to provide any form of tax, financial or legal advice.
