My partner submitted over 4,500 in medical expenses re 2012 but she had been on maternity leave and she didnt pay sufficient tax to receive the full 20% benefit. We didnt realise at the time that you can only claim what you have paid. As she only received half of what was potentially due, can I submit a claim using some of the same expenses now to make up the balance. My argument is that we wouldnt be receiving any more than had been initially claimed. Any thoughts?
