(1) The severance tax imposed under ORS 321.726 (Severance tax upon harvest from small tract forestland) is due and payable annually on or before the last day of January of each year with respect to all timber harvested during the previous calendar year.
(2) At the time at which the severance tax is paid and on or before the last day of January of each year, each taxpayer who has harvested any timber during the previous calendar year shall prepare a return on a form prescribed by the Department of Revenue showing the amounts and kinds of timber harvested for the previous calendar year, the amount of tax for which the taxpayer is liable for harvesting during the previous calendar year and any other information that the department considers necessary to correctly determine the tax due and shall mail or deliver the return, together with a remittance for the unpaid balance of the tax, to the department. The return shall be signed and certified by the taxpayer or a duly authorized agent of the taxpayer, as provided in ORS 305.810 (Verification of return, statement or document filed under tax laws). The department may allow, upon written application made on or before the last day of January, further time not exceeding 30 days for filing a return. The tax shall be delinquent if not paid by the last day of January, regardless of any extension of time for filing the return.
