If you had to withdraw funds from your RRSP in 2010, the good news is that you still have until March 1, 2011 to make a contribution to help offset your withdrawal. Although you will never get your contribution room back for the amount you took out, at least you won’t suffer as many tax penalties by putting some or all of the money back.
However, before you decide to put the money back, make sure that you can truly afford to do so. If you don’t already have some money set aside for emergencies, then it is probably better to refrain from adding any additional money into your RRSP. Why? Because you are just as likely to end up having to make another RRSP withdrawal and then it defeats the purpose of contributing to an RRSP altogether. Just be prepared to pay some tax in the Spring.
