Payroll Taxes

Oregon Tax Employer Reporting (OTTER)

OTTER is a free Windows based program provided by the Oregon Employment Department, for the electronic filing of the Oregon Combined Payroll Tax reports. If you do not have a Windows based program, you can file your quarterly report with SETRON if you have less than 50 employees.   


 OTTER Version 18.1.0 is available for download and installation.

*You must download this latest version if you plan to file using the OTTER system in 2018*


The update for OTTER 2019 will be available mid-March 2019.

Please find instructions and information below to download and install OTTER.  

**The new Statewide Transit Tax will not be included in OTTER. For more information about this tax, please visit the Oregon Department of Revenue's site:
