Here is a summary of the features of a tax free saving account:
Canadians 18 and older can put up to $5,000 per year into a tax free savings account.
Contributions to the TFSA will not be tax deductible but investment income, including capital gains, earned in a TFSA will not be taxed even when withdrawn.
Unused TFSA contribution room can be carried forward to the next year.
The amount withdrawn can be put back at a later date without affecting your contribution room.
Contributions to a spouse's TFSA is allowed and is transferable upon the death of the spouse.
