Newton County Tax Rates: Sales, Property, and Exemptions

Newton County tax rates come in two main forms: a combined 7% sales tax on most retail purchases and an annual property tax calculated from your home’s assessed value and the millage rates adopted each year by the county, school board, and any city you live in. The sales rate is fixed by law. The property bill depends on your home’s value, the exemptions you claim, and millage figures that shift from year to year.

Sales Tax Rate

The combined sales and use tax rate in Newton County is 7%. That total is a 4% state sales tax set by O.C.G.A. § 48-8-30 plus 3% in local taxes.¹ The three local components, each at 1%, are the Local Option Sales Tax (LOST), the Education Special Purpose Local Option Sales Tax (ESPLOST), and the Special Purpose Local Option Sales Tax (SPLOST).² Revenue from these local pieces funds county capital projects, school construction, and general operations.

Newton County does not currently impose a Transportation Special Purpose Local Option Sales Tax (T-SPLOST), which is why the combined rate here is 7% rather than the 8% seen in parts of metro Atlanta.²

Groceries and Prescriptions

Groceries bought for home consumption are exempt from Georgia’s 4% state sales tax under O.C.G.A. § 48-8-3(57), but the local 3% still applies at the register.³ So you pay 3% on qualifying food in Newton County, not the full 7%. Prescription medications are also exempt from state sales tax.

Property Tax: How the Bill Is Built

Property taxes in Newton County use millage rates. One mill equals $1 of tax for every $1,000 of assessed value.⁴ Your total rate is the sum of several separate levies. The Board of Commissioners sets the county maintenance and operations rate, the Board of Education sets the school district millage, and cities within the county may add their own.⁵ Fire protection and hospital authority levies may also appear.

These rates are adopted every year, so your total millage can shift even if your home’s value stays flat. The Newton County Tax Commissioner’s office publishes the current year’s rates on its website and at public meetings before final adoption. Confirm the latest figures there rather than relying on last year’s numbers.

The Calculation

Every bill starts with the fair market value assigned by the county Tax Assessor. Georgia law requires that taxable property be assessed at 40% of fair market value.⁶ A home the assessor values at $300,000 therefore has an assessed value of $120,000.

Next, any exemptions you qualify for are subtracted. If a standard homestead exemption reduces the taxable base by $2,000, the taxable value becomes $118,000. That figure is then multiplied by the combined millage rate. At a hypothetical total of 30 mills, the math is $118,000 ÷ 1,000 × 30 = $3,540 for the year.⁴

Check this math each year. The common errors are an inflated fair market value or a missing exemption. Both are fixable through the appeal process below.

Exemptions That Lower the Bill

Newton County homeowners can reduce their taxable value through several homestead exemptions. You apply once, and the exemption renews automatically as long as you stay in the same home.⁷

Standard Homestead

Any homeowner who occupies the property as a primary residence on January 1 of the tax year may apply. You must own the home and physically live in it.⁸

Senior Exemptions

Georgia layers several senior exemptions, each targeting a different tax:

Age 62 and older, school taxes: if combined household income is $10,000 or less (excluding Social Security and certain retirement income), you can exempt up to $10,000 of assessed value from school taxes, including taxes that retire school bond debt.⁸
Age 62 and older, inflation-proof county exemption: if total household income is $30,000 or less, you may lock in your county tax base so increases in appraised value beyond $10,000 don’t raise your county taxes. This replaces other county homestead exemptions and does not affect school or city taxes.
Age 65 and older, county taxes: a $4,000 exemption from all county ad valorem taxes if combined household income doesn’t exceed $10,000, again excluding Social Security and retirement income up to the federal Social Security maximum benefit.

The income exclusion matters. For 2025, the Social Security and retirement income exclusion covers up to $96,432, so many retirees whose income comes from Social Security or pensions still qualify even when their benefits exceed $10,000.⁸

Disabled Veterans

Veterans rated 100% disabled by the U.S. Department of Veterans Affairs, or rated less than 100% but compensated at the 100% level due to individual unemployability, receive an exemption of up to $50,000 on a homestead they own and occupy. It applies to state, county, municipal, and school taxes. The exemption also covers veterans with qualifying physical losses such as loss of use of limbs or eyesight.⁹ Surviving spouses may continue receiving it as long as they don’t remarry and stay in the home.

When to File

The traditional deadline for a homestead application is April 1 of the tax year. In most cases, missing April 1 means losing the exemption for that year.¹⁰ Georgia now also allows applications through the end of the 45-day window to appeal your annual assessment notice, which can effectively extend the deadline for some homeowners.⁸ File with the Newton County Tax Commissioner’s office. Bring a Georgia driver’s license and proof the property is your primary residence.

Appealing an Assessment

If the Tax Assessor’s fair market value looks too high, Georgia law gives you 45 days from the date on your annual assessment notice to file a written appeal with the county Board of Tax Assessors.¹¹ You can use the state’s PT-311 form or mail a letter stating that you disagree with the value and which appeal track you want.

Most homeowners default to the Board of Equalization. After the Board of Tax Assessors reviews your appeal and either adjusts the value or declines to change it, the case moves to the Board of Equalization, which must schedule a hearing within 15 days of receiving the appeal and hold it within 20 to 30 days of notifying you. Hearing officer and nonbinding arbitration tracks also exist, mostly used for higher-value commercial property.

One rule worth knowing: if the Board of Tax Assessors fails to respond to your appeal within 180 days, your claimed value automatically becomes the assessed fair market value for that tax year.¹¹

The evidence that actually wins appeals is concrete: recent sales of comparable homes near yours that sold for less than your assessed value, documented condition problems with contractor repair estimates, or plain assessment errors like wrong square footage or a garage listed on your record that doesn’t exist. Zillow estimates, complaints about the tax rate, and personal financial hardship are not accepted.

When to Pay and What Late Costs

Newton County property taxes are due by December 20 each year.¹² The local governing authority can move that deadline to December 1 or November 15, or set up installment billing, so check the Tax Commissioner’s site each fall to confirm the current year’s date.¹³ You can pay online through the Tax Commissioner’s website, by mail with a check or money order, or in person at the county offices.

Late payments carry interest at an annual rate equal to the federal bank prime loan rate plus 3%, calculated monthly. Any partial month counts as a full month.¹⁴ On top of interest, a 5% penalty on the unpaid original tax amount is added after 120 days of delinquency, and that 5% penalty repeats every 120 days until it reaches 20% of the original tax.¹² On a $3,000 bill, that penalty structure alone can add $600 before interest. One day late starts the clock.

Business Personal Property

Property tax here is not limited to real estate. Businesses that own tangible personal property such as equipment, furniture, fixtures, and machinery must report those assets annually. Georgia requires a PT-50P return filed with the county between January 1 and April 1 each year.¹⁵ Reported assets are assessed at 40% of fair market value and taxed at the applicable millage rate, same as real property.⁶ If you don’t file, the county may estimate your property’s value, which rarely favors the taxpayer.
