Tax relief and valuation review

Protect your exemption and appeal rights.

A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Grant County Assessor / Tax Collector.

Valuation cap or growth limit

Oregon Constitution Measure 50 generally limits maximum assessed value (MAV) to the greater of 103% of the prior year's assessed value or 100% of the prior year's MAV; taxable assessed value is the lesser of real market value and MAV. Exceptions include new construction, improvements, partition/subdivision, changes in use or status, and other statutory events; Measure 5 separately limits tax rates based on real market value.

Appealing an assessment

Build the objection around evidence and the notice date.

Calendar the window

Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.

Assemble support

Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.

File and preserve proof

Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.

The verified protest guidance for this county is: For the 2026 tax year, file with the county Property Value Appeals Board after the 2026 tax statement is mailed (generally October 2026) and no later than December 31, 2026; if December 31 falls on a weekend or legal holiday, the deadline moves to the next business day. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
