Question details
The user is unable to open an application form downloaded from Revenue Canada and needs help determining the file type and the correct software to open it.

- Product
- Device & OS
- not provided
- Scenario
- Attempting to access and view a downloaded tax form or application from the Revenue Canada website.
- Observed behavior
- The downloaded file fails to open, likely due to a lack of compatible PDF reader software, an unrecognized file extension, or an incomplete download.
Ensure that the file has finished downloading completely without network interruptions, and check the file extension (e.g., .pdf) to determine which software is required.
Verify the File Type and Redownload
Determine whether the file is a standard PDF or another proprietary tax software format, and redownload it to rule out file corruption.
Revenue Canada provides files in various formats. Knowing the exact file extension helps you choose the correct application to open it.
Right-click the downloaded file in your folder and select 'Properties' (Windows) or 'Get Info' (Mac). Check the 'Type of file' section to see if it ends in .pdf.
If the file size is unusually small (e.g., 0 KB), the download was likely interrupted. Delete the corrupted file and download the application again from the official Revenue Canada portal.
Open the Form Using a Dedicated PDF Reader
Many government applications are distributed as complex PDF files that require a desktop PDF reader instead of a web browser.
Easily Open and Fill PDF Forms with WPS Office
WPS Office includes a robust, built-in PDF reader and editor that can seamlessly open, view, and fill standard PDF documents, making it an excellent choice for handling downloaded applications.
- 1. Download WPS Office: Visit the official WPS website and install the free WPS Office suite.
- 2. Launch the PDF tool: Open WPS Office and click on the 'PDF' tab from the home screen.
- 3. Open your application: Click 'Open PDF', navigate to your Downloads folder, and select the Revenue Canada file to view and fill it.

Frequently Asked Questions
Why does my Revenue Canada PDF display a 'Please wait' error?
This error occurs because the file is a dynamic XFA form designed by the government, which modern web browsers cannot render. You need to save the file locally and open it using a dedicated desktop PDF reader.
How do I know if my downloaded application is a PDF?
Right-click the downloaded file and select 'Properties' (Windows) or 'Get Info' (Mac). Look at the 'Type of file' section; if the extension ends in '.pdf', it is a Portable Document Format file.
Can I fill out the Revenue Canada application on my mobile phone?
While standard PDFs can be filled out on mobile devices using apps like WPS Office for Mobile, certain complex government tax forms require a desktop PDF application to display interactive fields correctly.
