In the T2 return, lines 460, 465 and 480 exist on page 6 (under Refundable dividend tax on hand (for tax years starting before 2019)). In addition, the same lines exist on page 7 (under Refundable dividend tax on hand (for tax years starting after 2018)).
If you submitted a T2 return containing lines 460, 465 and 480 from page 7, these amounts are not being submitted to the CRA or included in the T2 barcode printout.
The CRA’s notice of assessment will include an automatic correction to add the missing amounts.
This issue was resolved in the last TaxCycle release.
