Missing the 30-Day Appeal Deadline for Property Tax Assessments

Knudsen Law Firm, PLLC understands that Montana property tax assessments carry a strict 30-day appeal deadline, starting from receipt of your property classification and appraisal notice—not the later tax bill. Our experienced tax attorneys emphasize that failing to meet this deadline permanently eliminates your right to contest the current year’s assessment, leaving you with potentially inflated valuations and higher tax obligations.
Our firm recognizes that late filings or informal requests can’t overcome this procedural requirement. Since 2016, we’ve helped clients understand that even the strongest supporting evidence becomes irrelevant if the initial filing window is missed. With our tax controversy experience, we help clients navigate disputes with tax authorities efficiently. Our tax law specialists recommend filing your AB-26 form with the county Clerk and Recorder immediately upon receiving your appraisal notice. Once your County Tax Appeal Board appeal is filed, you can expect your hearing scheduled between July 1 and December 31 of the current tax year.
