Thank you for getting back, @rtl999. I've got a solution to ensure that your W-2 report is properly formatted, allowing you to successfully upload it to Maryland Tax Connect without any further complications.

In order for the state of Maryland to successfully recognize your W-2 report, it’s essential to ensure that the file is saved in the correct format. This can be accomplished by adding the extension ".txt" to the end of the filename when you save the document to your chosen location on your computer. By doing so, you will meet the specific requirements set forth by the Maryland Tax Connect system, facilitating a smooth upload and minimizing the likelihood of any further issues during the submission process.
