The new fertility-related expenses can be claimed for the past 10 years. How are the expenses calculated for the past years?
E.g. If I had fertility-related expenses in 2015, are they added to my medical expenses from 2015?
If you incurred fertility related expenses in a prior year and had not included them as medical expenses in the year paid you will need to amend the applicable tax year for these additional expenses. They will be added on to any previously claimed or available medical expenses. You may have claimed an amount that was to low to be of benefit, but now with the additional expenses claim the total will generate a tax credit. Make sure that you are claiming the total of all expenses incurred during the tax year now including the Fertility Expenses. See below to learn how to amend a prior year tax return.
