Approved software vendors for corporation and fiduciary returns

2023 tax year

As of February 1, 2024, the following companies passed the Oregon Assurance Testing System (ATS) requirements for software developers of electronic corporate and fiduciary returns for the 2023 tax year. This means that their software uses the proper processing formats for both the IRS and Oregon. It doesn't mean that the software includes every possible schedule, attachment, or that it meets the needs of all filers. We are still testing vendors, and we will be updating this list periodically.

Providers are listed in alphabetic order.
