We kindly request you complete the form below and submit all of the necessary documentation to prepare your U.S. Business Tax Return. A reminder that your annual Agreement Letter has been sent to you and must be signed before Larson Gross can begin tax preparation.
To prevent any delays in your tax return preparation and filing, please submit your documentation as soon as possible.
We look forward to serving you!
IMPORTANT: Please ensure you have all of your documentation ready before completing the form below. The site is designed to timeout after a certain period of inactivity and we would hate for you to lose your work and have to start over.
In addition, there are multiple fields that will allow you to upload attachments below. Note that each individual field has a limit of 1, 5 MB document per field. If you have multiple, larger documents to upload, you may do that at the end of the form where you see this prompt: Please upload any additional documents necessary for properly preparing your tax return.
