Errors in TP-128 form CCA calculation in Turbotax Canada 2025

[TaiWai62]

In Turbotax 2025, as of February 11 2026, the CCA calculations in form TP-128 are incorrect in multiple places.

First, even though I have negative net income on the rental property, the TP128 still calculates a non-zero CCA which it uses to increase the loss.  This is wrong.  The available CCA in the case of a loss should be 0.

Second, columns 17, 20, 22 and 23 are incorrectly calculated. 

For example, Col 17 should be C17 = 1/2 * C10 - C11 - C9 - C5.  I have C10 = $251, C11 = C9 = C5 = $0. So the result should be approx $125, yet C17 shows $969. 

It turns out that $969 is the amount shown on the same line of C17 of federal form T776.  However, the values in form TP-128 should be the values that appear in T776 multiplied by the percentage ownership which in my case is approx. 13%...

As another example of error, all lines in C23 are zero despite there being much undepreciated property left.

Please make sure TP128 is tested.   In particular, please have a test case where ownership is not 100%!

Thank you!

We have sent this to an investigation. We have been informed that the forms are currently under development. Updates are continually being integrated into the CCA table. This is a known development status, not a bug. The CCA table is still dependent on the finalization of the CRA forms, and we are actively working to update the table as these forms become available. We appreciate your patience.

Thank you for choosing TurboTax.
