CO-17 Online Filing

Updated: 2017-04-28

TaxCycle T2/CO-17 is certified for online filing by Revenu Québec. This allows you to transmit Québec CO-17 corporate tax returns by internet to Revenu Québec. The process for transmitting CO-17 returns to Revenu Québec is very similar to transmitting T2 returns to the Canada Revenue Agency (CRA).

About online filing of the CO-17

This software allows the filing of the Corporation Income Tax Return (CO-17), the Information and Income Tax Return for Non-Profit Corporations (CO-17.SP) and related forms, including the Online Filing of the Corporation Income Tax Return by an Accredited Person form (CO-1000.TE). However, its use, as well as any omission or inaccuracy in the information provided, is the responsibility of the user.

Transmission par Internet de la CO-17

Ce logiciel permet la production de la Déclaration de revenus des sociétés (CO-17), de la Déclaration de revenus et de renseignements des sociétés sans but lucratif (CO-17.SP) et des formulaires connexes à celles-ci, y compris le formulaire Transmission par Internet de la déclaration de revenus d’une société (CO-1000.TE). Toutefois, son utilisation, de même que toute omission ou inexactitude dans les renseignements fournis, relève de l’utilisateur.

Register for NetFile Québec

In order to file the CO-17 return online, you must register for NetFile Québec. Learn more about how to do this on the Revenu Québec Mon dossier pour les représentants professionnels (page only available in French).
