Because Registered retirement savings plans (RRSPs) are registered with the CRA and come with tax benefits & limitations, internal transfers of either cash or investments out of these types of accounts have special considerations. (Unless the transfer is going to another RRSP for the same individual.)
Any transfers of cash or investments out of an RRSP are treated the same way as a regular withdrawal to your bank account in the eyes of the CRA, and may incur additional taxes.
You are taxed a ‘withholding amount’ when transferring funds or investments out of your RRSP to help cover any income taxes owing as a result of the transfer. The withholding amount may or may not completely cover any potential future taxes, this depends on your total overall income and other factors like deductions and etc.
For example: You have a yearly income of $45,000 and live in Ontario paying a base tax rate of approximately ~20% (Combined federal & provincial). If you transfer $5,000 out of your RRSP, the withholding taxes may not completely cover potential future income taxes.
If you transfer $16,000 however, you may be entitled to a tax refund, as the withholding amount is slightly higher than your base tax bracket.
Please double check with a tax professional if you have doubts about the tax implications of a transfer out of an RRSP.
Review the chart below to determine how the gross amount of your transfer will be taxed.
