City of Milton, GA Property Tax: Rates, Exemptions & Payments

Milton, Georgia property tax for 2025 is levied at a total city millage rate of 4.503 mills, made up of 4.193 mills for maintenance and operations and 0.310 mills for the greenspace bond. That rate is applied to 40% of your property’s fair market value, and the resulting city bill is separate from what you owe Fulton County and the Fulton County School District. Several homestead exemptions can reduce the city portion, and bills are mailed in late October with payment due in mid-December.

How the City Bill Is Calculated

Every property tax figure in Georgia starts with fair market value, set each year by the Fulton County Board of Assessors. State law reduces that value to 40% for tax purposes, and the result is your assessed value.¹

From there the math is simple. Multiply the assessed value by the millage rate and divide by 1,000. One mill equals one dollar of tax per $1,000 of assessed value. On a home appraised at $600,000, the assessed value is $240,000, and Milton’s 4.503 mills produces a city bill of roughly $1,081.²

Ownership and status are fixed as of January 1 each year. Buy a home in March and you won’t owe city tax on it until the next year’s cycle.³

What the City Bill Does Not Cover

The Milton bill is only one of three property tax bills that hit your home. Fulton County and the Fulton County School District each set their own millage rates and send their own bills, but all three levies use the same assessed value from the county Board of Assessors. The city’s online payment portal handles only the municipal bill; county and school taxes are collected by the Fulton County Tax Commissioner.⁴

Milton Homestead Exemptions

Milton offers its own homestead exemptions that reduce the taxable assessed value on the city bill only. To qualify, you must own and occupy the property as your primary residence as of January 1 of the tax year.⁵

Floating Homestead Exemption

The floating homestead exemption caps the annual increase in your taxable assessed value at the lesser of 3% or the inflation rate, plus any value from new improvements such as an addition or renovation. The city applies it automatically to any parcel that already has a basic homestead exemption on file with Fulton County, so no separate application is needed.⁵

Over time this cap can matter a lot. Even in a year when market values jump, the city can only tax you on a capped assessed value, and the gap between market value and taxable value tends to widen the longer you own the home.

Senior and Disability Exemptions

Milton also offers additional relief for older and disabled homeowners, applied to both the maintenance and operations and bond portions of the city levy:

Senior exemption for owners 65 or older as of January 1: a $25,000 reduction in assessed value, with no income requirement.
Full-value exemption for owners 70 or older as of January 1: exempts the entire assessed value from city taxes, effectively zeroing out the Milton bill. Household income cannot exceed $100,000 per year.
Disability exemption: a full-value exemption with no age requirement. Requires certification from a Georgia-licensed physician and household income no higher than the annual Social Security benefit maximum, which was $96,432 for 2025.

These are the exemptions that actually move your Milton bill.⁵

County and State Exemptions

Georgia’s state-level homestead exemptions reduce your county and school district taxes but do not lower your Milton city bill. Worth filing anyway, because they shrink the other two bills on the same property.⁶

Basic homestead exemption: $2,000 off assessed value for county and school taxes, for any owner-occupant as of January 1.
Senior exemption (65 or older): $4,000 off county taxes if household income (excluding retirement and Social Security income up to the federal maximum) does not exceed $10,000.
Disabled veteran exemption: exempts the greater of $32,500 or the maximum amount allowed under federal law from all ad valorem taxes for veterans rated 100% disabled by the VA, or those meeting specific qualifying conditions such as loss of use of limbs or eyesight. It extends to the veteran’s unremarried surviving spouse or minor children who continue to occupy the home.⁷
Surviving spouse of a peace officer or firefighter killed in the line of duty: full exemption from all ad valorem taxes on the homestead, for the unremarried surviving spouse. This exemption replaces rather than stacks with other homestead exemptions.⁸

How to Apply

Milton’s city exemptions and Fulton County’s exemptions are filed in two different places. Missing one does not affect the other, but skipping either leaves money on the table.

For the Milton senior and disability exemptions, file with the city’s Finance Department by April 1. You can drop the application off at Milton City Hall (2006 Heritage Walk, Milton, GA 30004) or mail it, as long as the envelope is postmarked by the deadline. Applications received after April 1 take effect the following tax year, and once approved, the exemption renews automatically unless ownership changes or you no longer qualify.⁵

For the basic homestead, senior, disabled veteran, and other state-level exemptions, file with the Fulton County Board of Assessors. The traditional deadline is also April 1, though Georgia law now allows applications up to the end of the 45-day window following your notice of assessment.⁷ Bring a valid Georgia driver’s license or state ID, vehicle registration for cars owned by you and your spouse, and, for senior or income-based exemptions, your state and federal tax returns or a Social Security award letter if you don’t file returns.⁹

Paying Your Milton Bill

Milton mails municipal property tax bills in late October, with payment due in mid-December. In the most recent cycle, bills went out the week of October 20 and were due December 17.¹⁰

Pay online through the city’s portal using your parcel identification number. Credit card payments carry a 3% service fee, and e-checks cost $1.75.¹¹ You can also pay in person at City Hall or by mail. Mailed payments must be postmarked by the due date to avoid late charges.

What Happens If You Pay Late

Georgia law imposes a structured penalty on delinquent property taxes. If you fail to pay within 120 days of the due date, a 5% penalty is added to the outstanding balance. Another 5% is added every 120 days after that, up to a total penalty of 20% of the original tax. Interest accrues on top of the penalties.¹²

One exception: penalties do not apply to homestead property when the delinquent taxes are $500 or less. Interest still runs, so even small balances grow.

If taxes remain unpaid by December 31, the Tax Commissioner is required by state law to issue a tax execution, known as a fi.fa. (short for fieri facias), against the delinquent property. A fi.fa. creates a lien on the property that is superior to virtually all other liens, including mortgages, and it can ultimately lead to a tax sale where the county seizes and sells the property to recover the debt. Once recorded, the fi.fa. stays attached until the full amount owed is paid.

Appealing Your Assessment

Because Milton’s bill and the county and school bills all use the same assessed value, an overvalued appraisal makes every bill too high. A successful appeal cuts them together.

You must file within 45 days of the date printed on your Notice of Assessment. There is no single annual deadline; your personal deadline is on your notice, and missing it forfeits the right to appeal for that year.¹³ File online through the Fulton County Board of Assessors portal, or submit a completed PT-311A form by mail or in person at 235 Peachtree Street NE, Suite 1200, Atlanta, GA 30303.¹⁴ Your appeal must include the parcel ID number, property address, and your estimate of fair market value as of January 1 of the tax year.¹⁵

When you file, you pick one of three appeal methods: the Board of Equalization, a hearing officer, or arbitration. If you don’t specify, the default is the Board of Equalization. Arbitration carries additional fees; a Board of Equalization hearing does not.¹⁴ The Board of Assessors reviews your filing first and may adjust the value on its own. If it doesn’t, or you disagree with the revised number, the appeal moves to a hearing where you present your evidence. You can also choose to be billed at 85% or 100% of the assessed value while the appeal is pending; the 85% option uses the lower of the current or prior year’s assessed value.

If the hearing outcome still doesn’t satisfy you, Georgia law allows a further appeal to Superior Court within 30 days of the Board of Equalization’s decision, provided you have paid taxes equal to at least the prior year’s amount.
