Payroll Taxes

OTTER is a free program that allows you to file your combined payroll tax reports electronically. 

OTTER 2015 v2.21.0 is now available. Please download and install this version in order to file your 2015 quarterly reports. It must be installed before a 2015 Oregon Quarterly Payroll Tax Report can be prepared and submitted.

Please make sure you back up your OTTER database before making any changes to your system. We recommend you complete a backup at the end of every quarter.
