Property Taxes on Perdido Bay: Two States, Two Systems, One Bay

Why This Page Exists: The Line Runs Through the Water, Not Around It

Most coastal markets on this site sit entirely within one state, and a property tax guide for them is a guide to one system. Perdido Bay is different by design: the Alabama-Florida state boundary, established as the Perdido River and ratified by both states in 1953, continues out through Perdido Bay itself along the bay's center line, per the U.S. Geological Survey's own hydrologic background documentation. That means two parcels facing each other across the same stretch of open water -- one near Lillian on the Alabama shore, one near Innerarity Point on the Florida shore -- are taxed by entirely different governments, under entirely different rules, even though they share the same view.

The practical first step for any buyer here, before looking at a single tax rate, is confirming which county a specific parcel is actually recorded in. A real estate listing, a GPS pin, or even a mailing address with an Alabama or Florida ZIP code is not a substitute for pulling the parcel's actual assessed value and taxing jurisdiction from the county property appraiser or revenue commission directly -- and a buyer's agent working this specific bay should be able to do that confirmation as a matter of course.

The Alabama Side: Baldwin County's Discounted-Assessment System

Alabama does not tax a home's full market value -- it taxes assessed value, a fraction of market value determined by the property's classification, before any millage rate applies. Owner-occupied residential property is Class III, assessed at just 10% of fair market value; non-owner-occupied residential property (a second home, a rental, an investment purchase) falls into Class II, assessed at a commonly cited 20% -- double the owner-occupied ratio. This single classification decision affects the tax bill more than most millage differences discussed below.

For unincorporated Baldwin County -- the status of most of Perdido Bay's Alabama shore, including Lillian and Josephine -- the combined millage is commonly cited around 31 mills: 6.5 mills statewide (3.0 of it earmarked for the state's Public School Fund), 10.02 mills for the county itself, and 14.58 mills for the Baldwin County school board. The incorporated city of Elberta layers its own 5.0-mill municipal rate on top for parcels inside its town limits, bringing that combined figure closer to 36 mills. This page did not independently confirm whether the incorporated town of Perdido Beach, on the bay's Alabama shore, levies a separate municipal millage of its own -- confirm directly with the Baldwin County Revenue Commission whether a specific Perdido Beach parcel carries a town-level rate beyond the unincorporated county baseline.

The Florida Side: Escambia County's Homestead-and-Cap System

Florida works on a fundamentally different logic. There is no discounted assessment ratio like Alabama's Class II/Class III system -- Florida taxes assessed value that starts much closer to a property's actual market value, then offsets that with exemptions and caps for a homesteaded primary residence. Escambia County, Florida sources cited total millage figures ranging from roughly 10.8 mills (one source's unincorporated-area average) to roughly 17.5 mills (another source's total countywide figure) -- a real disagreement this page states rather than resolves, likely reflecting different sampling areas, since Escambia County includes both incorporated Pensacola and multiple unincorporated communities with different combined rates.

For an owner who files homestead on a Florida primary residence, two protections meaningfully lower the effective bill: a homestead exemption reducing taxable assessed value by up to $50,000 (the first $25,000 applies to all property taxes including school levies; a second $25,000, on value between $50,000 and $75,000, applies to all levies except school taxes), and the Save Our Homes cap, which limits how much a homesteaded property's assessed value can rise in any single year to the lower of 3% or the Consumer Price Index -- a real, meaningful protection against a fast-rising local market that Alabama's system doesn't have an equivalent for. Neither protection applies to a second home, an investment property, or a buyer who hasn't filed for homestead status by the March 1 deadline for the tax year, having owned and occupied the home as of the preceding January 1.

A Worked Comparison -- Framework Only, Not a Bill

For illustration only: a $400,000 home on the Alabama shore, purchased and occupied as a primary residence (Class III, 10% assessment), has an assessed value of $40,000. At a roughly 31-mill unincorporated Baldwin County rate, that works out to about $1,240 a year ($40,000 ÷ 1,000 × 31) -- or closer to $1,440 inside Elberta's town limits at the added 5.0-mill rate. The same $400,000 home purchased as a non-owner-occupied second home instead lands at Class II's 20% assessment, doubling the assessed value to $80,000 and the tax bill to roughly $2,480 (unincorporated) or $2,880 (Elberta).

A comparably priced $400,000 home on the Florida shore, homesteaded as a primary residence, doesn't get a discounted assessment ratio -- but does get the homestead exemption's first $25,000 reduction against all levies plus a second $25,000 reduction against non-school levies, bringing taxable value down to roughly $350,000 in year one (before Save Our Homes limits future growth). At the lower end of the cited Escambia County millage range (roughly 10.8 mills), that's approximately $3,780 a year; at the higher cited figure (roughly 17.5 mills), it's closer to $6,125. This spread -- Alabama's roughly $1,240-$2,880 range against Florida's roughly $3,780-$6,125 range on an identically priced home -- is this page's own arithmetic applying separately sourced inputs on each side, not a single authoritative combined figure for either state, and it does not include any special district, fire district, or additional levy that could apply to a specific parcel on either shore. It also doesn't account for Florida's complete absence of a state income tax, a genuinely offsetting factor covered in more depth on this site's Retiring Here page.

What Changes If the Property Isn't Your Primary Residence

On the Alabama shore, buying as an investment or second home means Class II's 20% assessment ratio instead of Class III's 10% -- roughly double the tax bill independent of any millage difference, the same structural distinction covered on this site's Orange Beach and Gulf Shores property tax pages. On the Florida shore, a non-homesteaded property gets neither the homestead exemption nor Save Our Homes protection, meaning its assessed value can rise toward full market value more quickly and its taxable base starts higher from day one. In practical terms: the tax-cost gap between an owner-occupied purchase and an investment purchase is real and significant on both shores, but it's driven by different mechanisms -- a classification-based assessment discount in Alabama, an exemption-and-cap package in Florida -- and a buyer modeling a rental or second-home purchase here should not assume either state's owner-occupied estimate applies.

What a Buyer Should Actually Do

Before making an offer on any Perdido Bay property, first confirm with certainty which county the parcel sits in -- a title search or a call to the relevant county's property appraiser or revenue commission will settle this definitively where a listing description alone might not. Then pull the parcel's current assessed value and applicable millage directly from that county's own records, not from a real estate listing site's generic tax estimate, which is unlikely to reflect either Alabama's classification system or Florida's homestead-and-cap system correctly for a market this specific. If buying as a primary residence, ask specifically what's required to secure Class III status (Alabama) or homestead exemption and Save Our Homes eligibility (Florida) -- the paperwork and deadlines differ meaningfully between the two states, and this page did not independently confirm Alabama's current homestead-exemption or senior/disability relief program details at a level of precision it's comfortable stating as fact. Ask the relevant county directly about any additional relief program you might qualify for.
