Did my mortgage company pay my tax bill?

If your property tax bill is yellow, it means a mortgage company or senior/disabled citizen deferral program has requested tax information to pay your tax bill.

If you have recently paid off your loan, changed mortgage companies, or canceled your tax reserves, use this statement to pay your property tax.

If you have any questions regarding who is paying your property tax, contact your mortgage company or the Oregon Department of Revenue.
