General Tax Information

The ad valorem tax (more commonly referred to as the “property tax”) is the primary source of revenue for local governments in Georgia. Ad valorem means “according to value”, and property is taxed based on its assessed value. Assessed value, by law, is based on 40% of the fair market value as of January 1st every year. It’s set by the Chatham County Board of Assessors (Tax Assessors Office)

The millage rate is a determining factor in the calculation of taxes. A mill is 1/10 of $0.01 (or $1 per $1,000) of assessed value. Millage rates are set by the individual taxing entities.

The amount of taxes due are based on the assessed value of the property multiplied by the millage rate.

Real and Personal Property

Real property consists of real estate and any permanently affixed improvements, such as buildings.

Personal property consists of:

(a) Furniture, fixtures, machinery, equipment, inventory, or any other personal property used in business or (b) Aircraft and boats/motors owned by any individual or corporation.

Boats and motors are taxed in the county where they are “functionally” located (in a county in this State for a cumulative period of 184 days or more during the immediately preceding calendar year( for recreational or convenience purposes.

Aircraft are taxed at the location where hangered or tied down and where flights normally originate. Any aircraft having no permanent location are taxable at the domicile of the owner unless they acquire a business location elsewhere.

All tangible personal property of the taxpayer (except motor vehicles, trailers, and mobile homes). shall be exempt from ad valorem taxation if the actual fair market value of the total amount of taxable tangible personal property as determined by the Board of Tax Assessors does not exceed $7,500.

Tax Returns

A tax return is a listing of the property owned by the taxpayer and the taxpayer’s declaration of the value of the property. Taxpayers are required to file at least an initial tax return for taxable property (both real and personal property) owned on January 1st of the tax year. In Chatham County, the time for filing returns is January 1st through April 1st. These returns are filed with the Board of Assessors Office and forms are available in that office and online at

Once the initial tax return is filed, the law provides for automatic renewal of that return each succeeding year at the value finally determined for the preceding year and the taxpayer is required to file a new return only as additional property is acquired, improvements are made to existing property, or other changes occur. A new return, filed during the return period, may also be made by the taxpayer to declare a different value from existing value where the taxpayer is dissatisfied with the current value placed on the property by the Board of Assessors. This serves the purpose of establishing the taxpayer’s appeal rights if the declared value is changed again by the Board of Assessors.

Tax Assessments and Appeals

The Board of Assessors is required to issue a Notice of Assessment for Real Property annually and for any year where there is a change of value for Personal Property. Upon receipt of this notice, the property owner desiring to appeal the assessment may do so within 45 days. The appeal may be based on taxability, value, uniformity, and/or the denial of an exemption. The written appeal is filed initially with the Board of Assessors. The State of Georgia provides a uniform appeal form for use by property owners. In that initial written dispute, the property owner must declare their chosen method of appeal.

There are 3 methods of appeal: Board of Equalization method with further appeal to the Superior Court; Arbitration method which requires the appealing party to submit a certified appraisal within 45 days of the subject property which the Board of Assessors may accept or reject. If the taxpayer is sill dissatisfied, an appeal to the Superior Court may be made; Hearing Officer method for non-homestead real property with fair market value equal to or greater than $500,000 or certain wireless property with an aggregate value greater than $500,000 for appeals regarding value or uniformity with further appeal rights to Superior Court.

Homestead Exceptions

Property owners may apply for exemptions through the website or in-person with the Board of Assessors Office year-round. However, applications must be received by April 1st to receive the exemption for that year. These exemptions apply only to homestead property, which means the owners must own, occupy, and claim the property as their legal residence on January 1st to be eligible.

Once applied for and granted, the exemption shall automatically be renewed from year to year as long as the applicant continuously occupies the residence as a homestead and meets the exemption requirements. However, a new application must be made if the taxpayer bought and occupies a new home, had any type of deed change, or is eligible for a larger exemption. Only one person needs to apply if multiple names appear on the deed. The applicant must be eligible for the exemption applied for.

Homestead exemptions should not be affected by refinancing a mortgage unless the name is changed on the deed. Homestead exemption applicants need to know that any motor vehicle owned by the homeowner must also be registered in Chatham County (must have current and correct address & Georgia driver’s license).

Members of the Armed Services who maintain a legal residence and/or vote in another state are not eligible to claim a homestead exemption. The law specifically requires that the homestead must be the domicile of the owner. Military Personnel who claim homestead exemption are declaring their intention to become Georgia residents and are liable for State income taxes and ad valorem taxes on personal property.

To file for a homestead exemption, the property owner will need to provide the Chatham County Board of Assessor’s Office with the following:

a) A valid Georgia Driver’s License or Georgia ID Card

b) Registration for vehicles owned by the registered in the name of the applicant

As a supplement to the above, staff may also request the following:

c) A prior year utility bill or Chatham County Voter’s Registration card

Preferential Assessments and Tax Exempt Status

Two general types of specialized preferential assessment programs are available for owners of certain types of property.

One of those programs authorizes assessments at 30% rather than 40% of fair market value for certain agricultural properties being used for bona fide agriculture purposes.

The second type of preferential program is the Conservation Use Program which provides that certain agricultural property, timber land property, environmentally sensitive property, or residential transitional property is to be valued and assessed for ad valorem tax purposes at its current use value rather than the fair market value.

Each of these specialized or preferential programs requires the property owner to covenant with the Board of Assessors to maintain the property in its qualified use for at least 10 years in order to qualify for the preference.

The Board of Assessor’s Office can explain the ownership and use restrictions regarding property qualifying for either program. For more information, call 912-652-7271.
