Not sure if it is a Taxcycle or CRA issue but the “Year 2000 inclusion rate” from AFR seems to want to pull in a value of zero after AFR.
Could it be because the years given in the CRA data are all off by one (i.e. 2000 is showing as 2001) as compared to what you see in Represent a client. I would expect TaxCycle is prompting to bring in a zero because that is what came down for the year 2000, though it might have been meant for 1999.
Likely the cause. I will wait until they fix their issue and check that again.
