Payroll and Self-Employment Tax Information

Taxes that provide operating revenue for TriMet are administered and collected by the Oregon Department of Revenue.

Effective January 1, 2018, the tax rate increased to 0.7537% of the wages paid by an employer and the net earnings from self-employment for services performed within the TriMet District boundary. Employers should apply the new rate with their reporting related to wages for the first quarter of 2018. Self-employed individuals should use the new rate when first reporting earnings for 2018.

Employer Payroll Tax

Oregon employers are responsible for withholding the new statewide transit tax from employee wages. Starting July 1, 2018, the tax, which is one-tenth of 1 percent (or 0.001), must be withheld from the wages of Oregon residents — regardless of where the work is performed — as well as nonresidents performing services in Oregon.

Employers must also report and remit the taxes withheld quarterly (annually for domestic or agricultural employers). They also need to reconcile their quarterly or annual reports on their annual reconciliation return.

Employee Payroll Tax

Starting July 1, 2018, you’ll see a new item on your paystub for Oregon’s statewide transit tax. The tax is one-tenth of one percent (0.001), or $1 per $1,000.

Your employer will generally withhold the tax automatically — just like the personal income tax — so you shouldn’t need to do anything. (If you are an Oregon resident performing services outside Oregon for a non-Oregon employer, then you should ask your employer to withhold this tax from your wages as a courtesy — otherwise, you will be responsible for reporting and paying the tax yourself when you file your personal income tax return.) Unlike the personal income tax, there’s no withholding exemption for this tax.

Revenue from the statewide transit tax will go to expanding public transportation throughout Oregon. For more information on how the tax revenues will be used, take a look at the Oregon Department of Transportation’s Keep Oregon Moving page.
