This is the situation my sister finds herself in. She had a lot of medical expenses last year and filled out her Med 1 form in january. She is just about into the 41% tax band so she presumed she would get 41% of her expenses back. But the way the balancing statement is, she is only getting 41% of the amount she is paying in the higher bracket. The rest is at 20%. The really sickner is that she was married in 2007 and never bothered to change her tax to being a married couple. I have worked out that due to her husband earning more than her, that if they were taxed as a couple she would have got 741% of the full amount. My question is, is it possible to ask the revenue to change both their taxes to a married couple from the year they were married and get another balancing statement which would give her the difference in what she thought she'd get and the actual amount she got back? Sorry for the long winded way i asked the question but i suppose you need all the info before you can comment. Thank you in advance
