A TFSA lets you save or invest without paying any tax on the earnings you make. You can contribute up to $5,000 in 2009, and in 2010 you can put in an additional $5,000, plus any unused contribution room or withdrawals from the previous year. So no matter what you're saving for, BMO can help you make the most of your tax-free savings - and take the tax break you deserve today. Some things to think about to make the most of your TFSA.
