@tnvolfirefighter You should, as there are penalties to overcontributing. TFSA room increases every year. If you have automatic transfers from your bank to a brokerage account just look at the history of transfers and add them up. You don't have to wait for the CRA as it only updates that number once a year after you do your taxes.
While this is likely true I do find it infuriating that the CRA could give you an incorrect total on their website but also penalize you for over contributions. Especially when you have used their number.
@dummies01 They don't purposely give you an incorrect number.. it's correct at the point that they post it based on the information your bank gives them. They don't control the banks.
@dummies01 They give you an opportunity to move funds out. So just over contribute, wait for the letter or email from CRA on how much you are over limit and move that amount over to some other account.
