- You can overcontribute to your RRSP by up to $2,000 without being penalized. However, you cannot claim a deduction for the excess amount.
- If you overcontribute by more than $2,000, you are subject to a one per cent penalty tax for each month you are in excess of that. You have to complete a T1-OVP Individual Tax Return for RRSP Excess Contributions to calculate the amount of the overcontribution and penalty tax. This form must be filed, and the tax remitted, within 90 days from the end of the year (March 30, 2011 if there was an excess amount in the plan at the end of a month in 2010.)
