The funds in your First Home Savings Account (FHSA) have to be used by December 31 of the 15th year after opening your first FHSA account or the year you turn 71, whichever comes first. If you have not used the funds in your FHSA by that time, they can be transferred tax-free to your Registered Retirement Savings Plan (RRSP) without impacting your RRSP contribution room, or to your Registered Retirement Income Fund (RRIF); otherwise, your withdrawal will be taxed.
