Does Oregon tax Social Security?

What the Oregon Department of Revenue says

We do not paraphrase the rule from memory. This is the state's own wording, copied from the page linked below it:

Federal tax is a separate question

Even though Oregon does not tax it, the IRS can still tax part of your Social Security on your federal return. Whether it does depends on your other income. Our taxable Social Security calculator follows the IRS worksheet line by line, and this guide explains the rule.

You can ask Social Security to withhold federal tax from each payment. Withholding for Oregon state tax, if you need it, is arranged with the state, not with Social Security. State rules change with new laws, so check with the Oregon Department of Revenue before you file.
