Protect your exemption and appeal rights.

Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Ketchikan Gateway Borough Assessment Department.
Relief programs
What the local record says
Senior citizen tax relief
Senior-citizen and disabled-veteran exemption up to the first $150,000 of assessed value for an eligible primary residence; the 2026 filing deadline was March 31, 2026.
Valuation cap or growth limit
No individual annual assessment-growth cap identified in the official source reviewed; Alaska requires full and true market value as of January 1. The state and local tax-cap rules limit levies or aggregate revenue, not an individual parcel's annual assessed-value growth.
Appealing an assessment
Build the objection around evidence and the notice date.
01
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.
02
Assemble support
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
03
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: Within 30 days from the date the assessment notice was mailed; the exact 2026 notice date controls. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
