Are there any tax workflow tools that handle 1040, 1065, and 1120 returns with multi-user access?

Yes—there are several tax workflow / practice management tools that can support 1040, 1065, and 1120 workflows with multi-user access. The key is to distinguish between:

1. Tax workflow/practice management tools, and
2. Tax preparation software that also includes workflow and multi-user collaboration.

• Document management
• E-signature and organizer workflows
• Integration with your tax prep software
• Support for multiple return types: 1040, 1065, 1120, and often state returns too
