The deduction for stock options on line L-9 are already calculated by the company with the correct ratio of 25% or 50% for CCPC. The deduction from Releve-1 line L-9 should be carried over to line 297 - https://www.revenuquebec.ca/en/citizens/income-tax-return/completing-your-income-tax-return/completi...
Instead only half of the T4 box 39 deduction is carried over which would only apply to non CCPC companies
So after long calls with Intuit tax expert, who said yes it is a bug and a technical department who told me that they don't know and I should talk to their tax expert or even better upgrade their solution to even more expensive one I decided to go with H &R Block which calculated the taxes properly.
I have verified this appears to ignore anything in line. L-9 and in fact is using the summary deduction on the Quebec portion from the T-4 and not from the Releve -1. This is clearly an issue and for anyone getting any stock options it is a serious miscalculation.
