We have been following up with CRA on a few things and the details will be collected into a blog post soon.
We do know this… the Home Buyers Plan Repayment amount will be zero after you file the return, in cases where there was a value prior to filing the return. This is due to some of the CRA business rules for TDD.
We are going to add a warning against using TDD after filing a return.
Are there any other TDD differences the community has noticed?
