CO-17 Online Filing

Updated: 2021-03-09

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.

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.

Register for NetFile Québec

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

NetFile Transmission Options

Before you can transmit, you must enter your NetFile credentials in TaxCycle options:

  2. On the left side of the screen, expand Transmission and then click on EFILE Accounts.
  3. If your NetFile Québec number is the same as the one for the CRA, enter your EFILE Number and EFILE Password, then check the box to Use your EFILE Number for NetFile.

Resolve Outstanding Errors

In TaxCycle, you can see the filing status of any return in the Transmit sidebar. Outstanding errors that prevent filing appear there and in the Review sidebar. To resolve outstanding errors before transmitting:

  1. Click Transmit in the sidebar or press F12.
  2. Click once on the CO-17 Online Filing box to expand it and see a list of all outstanding errors. As you work, TaxCycle checks for errors that prevent filing. They appear in this box. Resolve them from this box like other review messages.
  3. Some messages may have Quick Fix suggestions, so you can fix the error without jumping to the form. Hover over the message and click on the lightbulb to see the suggestions.
  4. In any message, click the blue links to the form, field, spouse/dependant, or message that needs attention.

Confirm Signature of the CO1000

Revenu Québec requires that a taxpayer sign the appropriate sections on the CO1000 form before a preparer can electronically file on their behalf. TaxCycle requires you confirm the taxpayer has signed the TP1000 before you can transmit. Do this from the transmit sidebar:

  1. Click CO1000 link to open the form for data entry and review.
  2. Click on Print the CO1000 link to print the form using single-form printing. Read the Print/PDF a Form help topic to learn more about the options available from this box. TaxCycle records the date and the name of the person who printed the form.
  3. You can also send the CO1000 for electronic signature. See the Electronic Signatures help topic.
  4. Once you have a signed CO1000 on file, click the Confirm signature link. TaxCycle records the signing date and the name of the person who confirmed the signature.
