The primary source of income for Georgia counties is the property tax, which accounts for roughly 40 percent of the average county’s total revenue. Local sales taxes come in second, and together property and sales taxes make up well over half of all county revenue statewide. The rest arrives through user fees, intergovernmental grants, fines, and a handful of specialized excise taxes.
Why Property Tax Sits at the Top
Georgia’s ad valorem tax applies to real property such as land and buildings, and it funds county operations, municipal services, and public schools. For most counties, no other single source comes close.
The mechanics explain the scale. Georgia law requires taxable tangible property to be assessed at 40 percent of its fair market value.1FindLaw. Georgia Code Title 48 Revenue and Taxation 48-5-7 A home with a fair market value of $300,000 therefore carries an assessed value of $120,000. The local government applies a millage rate to that assessed value, where one mill equals $1 of tax per $1,000 of assessed value.2Georgia Department of Revenue. Property Tax Millage Rates If the county, city, and school district together levy 30 mills, that $120,000 assessed value yields a $3,600 annual tax bill before exemptions.
County and city governing authorities set their millage rates each year based on budgetary needs, and school boards set their own millage rates for education funding. Because multiple taxing jurisdictions can levy on the same parcel, a property’s total millage is the sum of every applicable levy. That stacking is a large part of why property tax dwarfs the other revenue lines.
Sales Taxes: The Second-Largest Stream
Georgia’s state sales tax rate is 4 percent. Local sales taxes stack on top, pushing combined rates in some counties to 8 or 9 percent. For counties, three local sales taxes do most of the work, and together they contribute roughly 18 percent of total county revenue on average.
Local Option Sales Tax (LOST)
LOST is a 1 percent sales tax shared between a county and the cities within it. The money flows into general funds and is intended to offset property tax burdens. How the county and its municipalities split the proceeds is set through a distribution certificate, and a new certificate must be filed after each decennial census. If the parties cannot agree on a new distribution within the statutory window, the tax ceases entirely and accumulated proceeds can eventually revert to the state.3Justia Law. Georgia Code 48-8-89 – Distribution and Use of Proceeds That consequence keeps both sides at the negotiating table.
When a new city incorporates within a county, the existing distribution certificate has to be renegotiated to include the new municipality.4Justia Law. Georgia Code 48-8-89.1 – Procedure for Certifying Distribution of Proceeds In fast-growing metro counties, this has been a steady source of friction.
Special Purpose Local Option Sales Tax (SPLOST)
SPLOST is a 1 percent sales tax reserved for capital projects: roads, bridges, public buildings, parks, libraries, jails, and similar infrastructure. Voters must approve it through a referendum. The maximum duration is six years when the county and its municipalities reach an intergovernmental agreement, or five years without one.5Justia Law. Georgia Code 48-8-111 – Procedure for Imposition of Tax Because the money can only go toward the specific projects listed on the ballot, SPLOST lets counties fund major capital needs without raising property taxes.
Education SPLOST (E-SPLOST)
E-SPLOST is another 1 percent tax, dedicated to school capital projects. It is authorized under the Georgia Constitution and administered by county and independent school boards. The money funds school construction, renovations, technology, and other capital expenses. Like SPLOST, it requires voter approval and runs for a limited term.
Fees, Fines, and Other Revenue
Taxes get the headlines, but a meaningful share of county revenue comes from sources that are not taxes at all.
User Fees and Enterprise Funds
Water, sewer, sanitation, and stormwater services typically operate through enterprise funds that charge users directly. The fees are meant to cover the cost of delivering the service rather than generate profit. Building permits, business licenses, and occupational taxes add to the total. Enterprise funds and public utility systems together make up a significant portion of county revenue statewide.
Hotel-Motel Excise Tax
Georgia counties and municipalities can levy an excise tax on short-term lodging at rates up to 8 percent of the room charge. Stays longer than 30 consecutive days are exempt, and the tax does not apply to government employees traveling on official business.6Justia Law. Georgia Code 48-13-51 – County and Municipal Levies For tourism-heavy areas, hotel-motel tax can be a surprisingly large line.
Fines and Forfeitures
Traffic tickets, code violations, and court penalties generate revenue, mostly for municipalities rather than counties. A few small cities have drawn scrutiny for leaning heavily on fine revenue, and Georgia’s legislature has moved in response. Proposed legislation would cap the share of a municipality’s revenue that can come from fines at 30 percent in 2027, dropping gradually to 15 percent by 2030, with any excess reverting to the state.
Intergovernmental Revenue
State and federal grants fund specific programs rather than general operations. Transportation projects, community development, and public health initiatives are frequent recipients. These grants often carry matching requirements or reporting obligations, so they expand a county’s capacity while adding administrative work.
How County Revenue Differs From City Revenue
Counties and municipalities serve overlapping but distinct roles, and their revenue profiles reflect that. Counties cover services across unincorporated areas and typically fund public schools, courts, and the jail. Property taxes dominate county budgets at around 39 percent of total revenue, with sales taxes contributing roughly another 18 percent.
Municipalities lean more heavily on enterprise funds from water, sewer, and other utilities, and on sales tax revenue generated within their commercial districts. That difference is where the LOST distribution fight tends to flare up. A city with a strong retail base argues it generates the sales tax and deserves a larger share. The county counters that it serves unincorporated residents who shop in the same stores. The decennial renegotiation can get heated, and the statutory penalty of losing the tax entirely if no deal is reached is what forces resolution.
SPLOST adds another layer. The county governing authority initiates the referendum, but the project list typically includes proposals from participating cities. A well-structured SPLOST ballot spreads projects across the county to build voter support, which means even small municipalities can secure funding for parks, fire stations, or road improvements they could not finance on their own. For the county itself, SPLOST and E-SPLOST are the main way large infrastructure and school capital projects get built without pushing millage rates upward, which keeps the property tax — the largest revenue source — politically sustainable year after year.
