COBB COUNTY TAX APPEAL FAQ

45 days from Assessment Notice. Appeals must be formally lodged with the Cobb County Board of Equalization before the statutory deadline expires. Filing past this cutoff forfeits your legal right to an assessment reduction for the active tax year.
No. Under Tennessee law (Tenn. Code Ann. § 67-5-1407(b)), taxpayers may execute a Written Appearance Hearing Waiver (Exhibit W). Untax automatically compiles this certified instrument, allowing the Board of Equalization to rule on your appraisal purely based on certified roll evidence without requiring your physical attendance.
We index 285000 parcels directly from the official county assessment roll. Our valuation algorithm identifies 5 to 7 certified comparable properties within your immediate neighborhood code, matching building square footage, year built, exterior wall grade, and land topography to establish mathematical non-uniformity under IAAO standards.
