again.You can find the criteria the married couple's allowance here.You and your wife were both born before 6 April 1935 but you aren't living together as a married couple and you don't appear to be separated through circumstances which would allow you to keep the married couple's allowance as set out here so really you should not have been claiming it since the late 1980's..In tax terms today, the allowance isn't worth much but over 28 years, the tax relief you have had will not be insignificant.I cannot tell you what to do I'm afraid as that is something you are going to have to decide but if you do tell the tax office that you have been claiming the married couple's allowance under the misapprehension that you could, I doubt that they will go back 28 years and ask the tax saving you have had back but nothing is impossible. They may go back six years or if you are lucky, somebody may take the decision to leave the past alone, stop the allowance from now on and cite your age as a mitigating factor so.The fact that you haven't told HMRC of your address since you separated doesn't help your case. I'm afraid that you are stuck between a rock and a hard place. If you do decide to tell HMRC and they beocme difficult, then I'd advise you to contact your local Citizens' Advice Bureau or the people here.I hope this helps but let me know if you have any further questions.
