Marshall County Tax Map: Parcel Search, Assessments, and Appeals

The Marshall County tax map is a free online GIS portal run by the Marshall County Revenue Commissioner’s Office in Alabama. You can pull up any parcel in the county by owner name, parcel number, or PPIN and see its boundaries, acreage, assessed value, tax district, and deed references without leaving home.¹

Opening the GIS Portal

Go to the Revenue Commissioner’s website and open the “GIS Maps and Property Searches” page. That page links directly to the mapping application. Before the map loads, you’ll be asked to accept the site’s terms of use.¹

Nothing needs to be installed. The portal runs in any standard browser on a desktop, tablet, or phone, and it’s available around the clock. The Revenue Commissioner is the only office that maps every parcel in the county and assigns valuations to them, so this is the authoritative source rather than a third-party site.²

What to Search With

The system takes three kinds of input: the owner’s name, the parcel number, or the PPIN (personal property identification number). You only need one.¹

Parcel number is the most reliable. It appears on your annual property tax notice and near the top of the recorded deed, inside the legal description. Owner name works too, but multiple people share names, so match the formatting on official records. “John A. Smith” and “John Smith” can return different results.

Once you run a search, the system lists the matching records. Click the correct one and the map centers on that parcel. Scroll to zoom, drag to pan, and use the layer menu to switch between the standard topographic view and satellite imagery. Satellite view helps when you want to see structures, tree cover, or terrain lined up against the parcel boundaries.

What the Parcel Record Shows

Every parcel record pulls together the information the county uses to assess and tax the land:

Lot lines and total acreage, with dimensions in feet drawn from historical survey data.
The assessed value of the land and any improvements. This is the figure that drives your tax bill.
The taxing district, which sets the millage rate that applies to the parcel.
Links to the most recent recorded deed, giving you an ownership paper trail.
Symbols marking easements, rights-of-way, and zoning classifications that affect how the land can be used.

How the Assessed Value Becomes a Tax Bill

The assessed value on the map is not fair market value. Alabama sorts property into four classes and assesses each at a fixed percentage of market value:³

Class I, utilities: 30% of fair market value.
Class II, commercial and industrial: 20%.
Class III, residential, agricultural, and forest land: 10%.
Class IV, private passenger vehicles: 15%.

Most homes fall in Class III. A $200,000 house has an assessed value of $20,000. Your bill is that assessed value multiplied by the millage rate for your area, then divided by 1,000.

Marshall County millage rates run from 37.5 mills in rural areas and smaller communities like Douglas and Union Grove up to 50.0 mills in Boaz. Other rates include 46.5 in Albertville, 43.0 in Guntersville, 42.5 in Grant and Cherokee Ridge, and 40.5 in Arab. Some areas also add a flat $60 fee for volunteer fire district coverage.⁴ For that $200,000 home in Boaz: $20,000 × 50.0 ÷ 1,000 = $1,000 per year before exemptions.

Homestead Exemptions That Lower the Bill

If the parcel is your primary residence, a homestead exemption can reduce or eliminate the tax. Alabama offers four tiers:⁵

H1, standard: any homeowner. Exempts $4,000 of assessed value from state taxes and $2,000 from county taxes.
H2, age 65 or older with Alabama adjusted gross income of $12,000 or less but federal taxable income above $12,000: exempts all state property tax and $5,000 of assessed value from county taxes, including school taxes. Must be renewed each year.⁶
H3, age 65 or older with combined federal taxable income under $12,000, or anyone permanently and totally disabled regardless of age or income: exempts all property taxes on up to 160 acres.
H4, age 65 or older with income above the H2 and H3 thresholds: partial exemption with no income cap.

Exemptions don’t appear automatically on the tax map. You apply at the Revenue Commissioner’s office. If you’re looking at a high assessed value on a home you own and live in without an exemption on file, that’s worth a call.

Tax Lines Are Not Legal Boundaries

The parcel lines on the map are drawn from recorded deeds and surveys, but they exist for assessment. They are a graphic representation, not a legal boundary. A tax map will not settle a fence-line disagreement with a neighbor.

Genuine boundary questions require a licensed land surveyor to work from the deed calls, recorded plats, and physical monuments on the ground. The county cartographer is specifically instructed not to interpret or settle boundary disputes. When conflicts or encroachments turn up during map updates, the cartographer marks them with hash lines and moves on.⁷

Use the map for identifying parcels, checking assessed values, reviewing ownership, and confirming your tax district. For anything involving legal lines, hire a surveyor.

Correcting Errors on the Map

If the map shows wrong boundaries, wrong acreage, or an outdated owner, the Revenue Commissioner’s Office has a formal correction process. Errors are reported on a Parcel Error Change Form (RP-16) and reviewed by the county cartographer.⁷

What you need to bring depends on the error. Ownership mistakes usually take a copy of the recorded deed showing the correct information. Boundary or acreage errors typically need a new survey recorded with the county. Contact the Revenue Commissioner with your parcel number and a description of the problem, along with the supporting documents. Corrections that require a new survey take longer, because the surveyor’s plat has to be recorded before the map can be updated.

Disputing the Assessed Value

If the assessed value on your parcel looks too high, you have 30 days from the date you receive written notice of a valuation change to file a written protest with the Marshall County Board of Equalization.⁸ Assessment records are available for public inspection, and the values on the map are the same ones used on your bill.⁹

Bring evidence. Comparable sales for similar properties nearby, a recent independent appraisal, or proof that the tax map has a factual error such as wrong square footage or lot size all strengthen a protest. The board reviews the evidence and rules. If you disagree with its decision, you can appeal to circuit court within 30 days, but to keep that right you must either pay your taxes by December 31 or post a bond in circuit court for double the amount owed.
