Rate Breakdown

Property taxes in Henry County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Henry County

Henry County property taxes are calculated by multiplying the assessed value of a parcel by the county’s combined millage rate. The assessed value is determined by the Henry County Board of Assessors, who appraise each property at a percentage of its market value (generally 40 % for residential real‑estate). Once the assessment is finalized, the tax bill is generated using the total millage rate set by the County, the City of McDonough, school districts, special districts, and any voter‑approved initiatives.

• Assessment process: The Board of Assessors updates market values every year, sends a notice of assessment in January, and provides a 30‑day window for owners to request a review.
• Millage rates: A “mill” equals one‑tenth of a cent ($0.001). In 2024 the combined rate for most residential parcels is approximately 27.5 mills (2.75 % of the assessed value), but the exact rate varies by location within the county.
• Tax bill calculation: Tax due = Assessed value × (Combined millage ÷ 1,000). For example, a home assessed at $80,000 with a 27.5‑mill rate would owe $2,200 in property taxes.

Available Exemptions

Georgia offers several exemptions that can lower your Henry County property tax liability. Eligibility is determined by state law and must be applied for through the County Tax Commissioner’s Office.

• Homestead exemption: Provides a $2,000 reduction in the assessed value for owner‑occupied primary residences.
• Senior citizen exemption: Residents 65 years or older who meet income thresholds may receive an additional $2,000 exemption and may qualify for a supplemental “circuit breaker” credit.
• Disability exemption: Persons with qualifying disabilities can obtain a $2,000 reduction, plus a possible additional credit if the disability is severe.
• Veteran exemption: Armed Forces veterans with a service‑connected disability of 100 % are exempt from county property taxes; those with a lesser disability receive a $2,000 exemption.

Payment Schedule & Deadlines

Henry County property taxes are due in two installments. Timely payment avoids penalties and interest, and an early‑bird discount is available for certain counties in Georgia (though not currently offered in Henry County).

• First installment: Due November 1; must be paid in full by December 20 to avoid a 10 % penalty.
• Second installment: Due March 1; full payment required by April 20, after which a 10 % penalty plus interest accrues.
• Payment methods: Payments can be made online via the Henry County Tax Commissioner portal, by mail, in person at the County Tax Office, or through authorized banks.
• Late consequences: Unpaid taxes after the second deadline may result in a tax lien, wage garnishment, or foreclosure.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you have the right to appeal. The appeal must be filed with the Henry County Board of Equalization before the statutory deadline (typically May 31 of the assessment year).

• Step 1 – Gather evidence: Compile recent comparable sales, an independent appraisal, or photographs that demonstrate condition and market value.
• Step 2 – File the appeal: Submit a written protest and supporting documents to the Board of Equalization, either online or in person. A filing fee may apply.
• Step 3 – Attend the hearing: A hearing officer will review your case; you may present witnesses or additional data.
• Step 4 – Receive the decision: The Board issues a written determination, usually within 30 days. If unsatisfied, you may appeal to the Superior Court of Henry County.
