The Division of Revenue often receives inquiries from taxpayers and tax preparers regarding the status of e-file vendors, as well as the status of vendor forms.  To assist taxpayers, the following is a list of the vendors who have requested approvals from the Division of Revenue, together with the forms and services of that vendor that have been approved to date.

Approved E-File and Substitute Paper Tax Form Vendors

The following software vendors are offering approved 2019 forms for taxpayers for Delaware’s electronic filing (eFile) program as part of the Federal/State E-File Program. Developers and products will be added to the list as vendors are approved.

Software vendors appearing on this list have products that have passed the review and testing procedures established by the Division of Revenue. The review, however, does not include the accuracy of the software program or the program’s calculations. Electronic tax preparation services are provided by independent commercial companies, and the scope of and approach to tax return preparation and filing vary among service providers.

Please carefully read the information provided by each company to fully understand the services it offers. Requests for assistance with software must be directed to individual service providers, not the Delaware Division of Revenue. The Division is not liable for and does not assume any responsibility for the accuracy of these income tax filing products or programs. While the Division promotes electronic tax preparation and filing, it does not endorse or recommend any specific company, its products or services.
