Although the official deadline has passed now to be able to use your RRSP contributions for the 2010 tax year, it doesn’t mean that RRSP season is over. In fact, it is better to contribute to your RRSP all year round than wait until the last possible minute to put a lump sum into it.
This year I challenge you to set up automatic payments into your RRSP every time you get paid. That way you will not have to burden yourself with coming up with a lump sum every year. If you discover that you still want to put in more, then you can top up your contributions before the deadline, but the lump sum will be far less of a burden.
