Gwinnett County Commercial Property Tax Appeals

Georgia assesses property at 40% of fair market value statewide, and Gwinnett is no exception. The county Board of Tax Assessors determines fair market value, and the assessed value is simply 40% of that figure before the local millage rate is applied. Because the 40% ratio is fixed by statute, a commercial appeal is entirely a fight over the assessors' market value conclusion. Lower the market value and the assessment and the tax bill follow it down. The distinction matters more than most owners expect, which is why we walk through assessed value versus market value at the start of every review.

You elect one of three routes when you file with the Board of Tax Assessors, and the election is largely use-it-or-lose-it. The County Board of Equalization, a three-member citizen panel, is the default and the most common choice. Binding arbitration puts the value decision in an arbitrator's hands. A hearing officer is available for non-homestead real property with a fair market value of $500,000 or more, which covers most Gwinnett commercial buildings. Decisions from any of the three can be appealed to Superior Court, and the Georgia appeal process page explains how each route compares.

Gwinnett is one of Georgia's fastest-growing counties, and its mass-appraisal models are chasing a rapidly moving market. Those models lean heavily on recent sales, so a cluster of aggressive transactions in Suwanee or Buford can pull up values across an entire submarket. The result is frequent year-over-year jumps on properties whose actual rents, occupancy, and operating income have not moved at all. That disconnect between sales-driven modeling and real property performance is exactly what an income-based appeal is built to expose, and it is why owners of office buildings and shopping centers here so often find a gap worth challenging.

Usually. Under O.C.G.A. § 48-5-299(c), a value established through an appeal is generally frozen for the two following tax years, so one successful appeal can lock in savings across three years. The freeze protects the value, not the tax bill, because millage rates can still change. Standard exceptions apply: new construction, substantial improvements, or the owner filing a return at a different value can end the freeze early. In a county where assessments move as fast as Gwinnett's, that multi-year protection is a large part of what makes appealing worthwhile, and it changes the math in our DIY versus professional appeal comparison.

We represent owners across the full commercial spectrum in Gwinnett, including office and flex product in Norcross and Peachtree Corners, retail along the Mall of Georgia corridor in Buford, warehouse and distribution buildings on the I-85 corridor, multifamily throughout Lawrenceville and Duluth, plus healthcare, self-storage, and data center properties. Each type calls for a different valuation approach, and mass appraisal tends to flatten those differences. Matching the right method to the property is where most of the reduction comes from.

Very often, yes. A recent sale is the single strongest piece of evidence Gwinnett's assessors have, and in a fast-moving market they tend to treat the purchase price as a floor rather than one data point among many. If you bought a partially leased asset, paid for future upside, or acquired a portfolio where the allocation to this parcel was not market based, the resulting assessment can overstate what the property is actually worth as it stands today. A post-purchase appeal filed in the first eligible year also positions you to capture the 299(c) freeze on the way in. Our guide to appealing property taxes after a purchase walks through the evidence that works.

We work primarily on contingency. Beyond a modest filing retainer up front that covers filing fees and case costs, our fee is owed only if we reduce your assessment and save you money. Georgia charges no county filing fee to appeal unless the case is escalated to Superior Court, which keeps the cost of entry low. Because a Gwinnett reduction can carry across three tax years under the 299(c) freeze, the return on a successful appeal is usually measured well beyond a single tax bill.
