Download corporate information

  1. Create or open a T2 tax return in TaxCycle. Enter at minimum the corporation's name and business number (BN).
  2. Make sure you have authorization to represent each taxpayer by ensuring your client has authorized you as their representative through My Business Account or by filling out and sending Form RC59, Business Consent, to get online access.
  3. If TaxCycle has a record of a valid RC59 on file and a date entered in the table on the Engagement worksheet, you will see a bulletin at the top of the screen to remind you that data may be available to download.
  4. Click the Start T2 Auto-fill button in the bulletin.
  5. If you don't see a bulletin, go to the Data menu and click on T2 Auto-fill.
    Start T2 Auto-fill
  6. In the T2 Auto-fill dialog box, check the corporation for whom you want to download information.
  7. TaxCycle also shows you the status of the RC59 in dialog box. You can still select a corporation without a valid RC59 recorded in TaxCycle and make a request. If the CRA system returns data, then TaxCycle will update their status to show an RC59 on file.
  8. Click Next to launch your web browser and connect to the CRA.
  9. The CRA Login page will display. Enter your CRA User ID and Password and click Login.
  10. The request confirmation page will display, listing the BN for the requested corporation. Click Next.
  11. As the download begins, a message displays to prompt you to close your browser window or tab. If you intend to return to download more information within the next few minutes (your login will remain open for 18 minutes), you do not need to log out. If you are done for the time being, click the link to logout from CRA before you close the window.


Import T2 Auto-fill data

  1. Back in the TaxCycle T2 Auto-fill dialog box, you will see a summary of the data available for download.
  2. To download (re)assessed tax return data, choose the year end. This downloads the .COR file that was transmitted with that year's return. You can only download one year's (re)assessed return at a time.
  3. By default, the option to Save a copy of the data file with the tax return is checked. This means that the file will appear in the same folder as the T2 TaxCycle file. Clear this check box to only save the file within the TaxCycle file history. See the section on "(Re)assessed returns from previous years," below.
  4. Check or clear the boxes to select the Other tax data you wish to import into TaxCycle.
  5. Click Download Tax Data.
  6. TaxCycle downloads the data and shows a summary of where the imported data will appear. In general any data downloaded is imported into the T2 Auto-fill worksheet.
  7. Click on a row to display a preview of the downloaded data and the form into which it will be imported.
  8. On the preview side of the window, use the arrows to move through the slips one-by-one.
  9. At the bottom of the dialog box you will see a note about when the data was downloaded and by whom.
  10. Check Show T2 Auto-fill worksheet after import to open the Imported (including AFR) view in the Prepare sidebar and open the T2 Auto-fill (AFR) worksheet.
  11. Click Download again to start the download process again. Auto-fill data does not change over the course of a day (it happens overnight). This means that if you download data in the morning, it will be the same in the afternoon. With this in mind, if you attempt to download a second time, it will jump straight to the match and import screen.
  12. Click Import data to put the data onto the worksheet.
  13. Click Close to close this window and not import any data at this time. The data you downloaded is still available if you return to the T2 Auto-fill process.


How to address download errors

Occasionally, a T2 Auto-fill will fail to complete due to an issue with the data received from the Canada Revenue Agency (CRA).

The Canada Revenue Agency (CRA) has told us that if you receive this type of error message, there is an issue with the CRA system and we should inform them. If you receive this error, please contact TaxCycle support.

If this occurs, TaxCycle will display the detail of the error received from the CRA. The error can be related to one of four system issues from the CRA related to:

  • the .cor file
  • T2 balances (T2 return balances such as RDTOH, GRIP, etc.)
  • accounting balances (corporate account balances)
  • business number and address (corporation business number data)

For example, if an error code is “T2 balances”, TaxCycle now displays the following error message:


If you encounter one or more of these four error messages:

  1. Click the Download again button to re-start T2 Auto-fill.
  2. Clear the check box that suggests using the prior download.
  3. Click Next.
  4. When you get to the step that allows you to select which data to download, clear the check box next to the type of data mentioned in the error. If the error mentions the:
    1. The .cor file, clear the top two boxes.
    2. T2 balances—such as RDTOH, GRIP, etc.—clear the check box next to T2 return balances.
    3. Accounting balances/corporate account balances, clear the check box next to Corporation Account Balances.
    4. Business number address/corporation BN data, clear the check box next to Corporation BN data.


T2 Auto-fill worksheet

The T2 Auto-fill worksheet contains information downloaded from the CRA. TaxCycle uses the information inserted in this worksheet to check for mismatches between the information in the tax return. For example, it uses this data to trigger review messages if the downloaded data does not match what is in the return.


(Re)assessed returns from previous years

Data for (re)assessed returns is downloaded as a .COR file. This is the same format used when transmitting the return via T2 CIF.

  1. When downloading from T2 Auto-fill, you can choose to save a copy of the .COR file in the same location as the TaxCycle file. (You can only download one year at a time, see above.)
  2. Each download of a .COR file is recorded in the table on the T2 Auto-fill (AFR) worksheet.
  3. Click the drop-down arrow on the right side of the field (or right click on a row) to Open the file or Show the file in the containing folder.
  4. You can view the contents of the .COR in a text editor. Notepad cannot interpret the carriage returns in .COR, so the text appears all on one line. If you wish to see it in a better format, use a more advance editor (such as Notepad++).


Show all T2 Auto-fill review messages

  1. Click on the Review sidebar.
  2. Choose T2 Auto-fill from the views menu at the top of the sidebar to see a list of AFR-related review messages.
