When I am trying to preview the T4 Employer Slips, I get an error displaying form message instead of the T4's. How do I correct this?

When I am trying to preview the T4 Employer Slips, I get this message: Error displaying form Form not available at this time. Error reason:The requested form is not ready yet. Newly created data is still being processed. Please try again in a few minutes. The T4's don't display. I've tried several days in a row now and am having no luck.

Hi there, manderson. The T4 preview error can occur when QuickBooks Online is temporarily unable to load the form correctly. This can happen if the form generation hasn’t fully completed or if the system is having trouble displaying the file.

Since this issue has persisted for several days, I recommend contacting our live expert during their available hours, for further investigation and to identify the root cause.

If you have any further questions, please feel free to comment below.
