On October 16, 2009 the Minister of Finance announced proposed amendments to the Income Tax Act to strengthen the rules applicable to Tax-Free Savings Accounts.  These amendments:

	Make income from deliberate overcontributions and prohibited investments subject to existing anti-avoidance rules in the Income Tax Act
	Make income attributable to non-qualified investments taxable at regular income tax rates.
	Ensure that withdrawals of deliberate overcontributions, prohibited investments, non-qualified investments or amounts attributable to swap transactions, or of related investment income, from a TFSA do not create additional TFSA contribution room.
	Prohibit asset transfer transactions (swap transactions) between TFSAs and other accounts.

Information on the changes is included in the articles below.  The amendments apply to transactions which occur after October 16, 2009.  The draft legislation and explanatory notes were released by the Department of Finance on April 30, 2010. The amendments were included in Bill C-47, which became law in December 2010.
