Tax relief and valuation review
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 Cobb County Board of Tax Assessors.
Relief programs
The filing guidance for this county is: July 20, 2026; Cobb County's official 2026 assessment information lists July 20 as the homestead-exemption filing deadline. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationCobb County's official assessor FAQ states the county school-tax exemption is administered by the Tax Commissioner's Office for qualifying owners age 62+; current forms and eligibility must be confirmed with CobbTax.gov.
Cobb County's floating homestead exemption protects qualifying primary residences from county-general-fund tax increases caused solely by reassessment by increasing the exemption; each home has a base-year value that changes for improvements or land changes.
Appealing an assessment
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.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
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: 45 days from the date on the 2026 Notice of Assessment; Cobb County's official appeal FAQ states Georgia law provides 45 days and no extension. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
