If you mean she didn’t make up the missed Ramadan fasts due to menstruation then she’s sinful for not making them up till now. She must repent to Allah sincerely and must start making them up from now on. 

There is a friend of mine who hasn’t repaid the last two year’s left out fasts and this year’s ramadhan has passed. What would you advise them to do.

My brother passed away this past July. I know we can make dua and fast on behalf of the deceased. My question is I’ve fasted on the day of Ashoora on his behalf. Will he get the reward of sin being wiped away from previous year? Of course sins being forgiven for the following year wouldn’t count because he is no longer in this world.
