If the maximum has been contributed to a TFSA, and then a withdrawal is made, no further amount can be
contributed (without penalty) until the following
year. On January 1st of the following year, the withdrawal amount from the previous year will be
used to increase your regular annual contribution room.
October 16, 2009 proposed amendments to the
Income Tax Act will include rules to ensure that any withdrawals of
amounts regarding deliberate overcontributions, prohibited investments,
non-qualified investments, asset transfer transactions and income related
to those amounts do not constitute withdrawals for TFSA purposes, and do
not create additional TFSA contribution room.
