Frequently asked questions

How is capital gains tax different in Canada?
Canada doesn't tax the full gain — only the 50% 'inclusion' portion is added to income and taxed at your marginal rate. (A proposed increase to 66.7% on large gains was shelved, so 50% applies.)
What's the US long-term rate?
0%, 15%, or 20% depending on your taxable income. Enter the rate that matches your bracket.
