If any person neglects or refuses to pay an income tax at the time of assessment, or fails to pay to the Department of Revenue any amount required to be withheld under ORS 316.167 and 316.172, the amount of the unpaid tax including interest and penalty thereon shall be a lien in favor of the State of Oregon upon all property and rights to property, whether real or personal, belonging to the person. The lien shall arise at the time of assessment or the time the amount withheld is to be paid to the department and the lien shall continue until the liability for the taxes, with interest and penalty, is satisfied.
