"All properties are considered non-owner occupied unless an owner assesses otherwise." That sentence sits near the bottom of the Cullman County Revenue Commissioner's homestead exemption page, right below the rules for primary residences. Weekend buyers on Smith Lake often skip past it, and it is one of the most expensive sentences on the page.
Here's what it means in practice. A lake house used only by its owner can qualify for Alabama's lower residential assessment rate, the same rate a full-time resident gets. The county doesn't apply that rate on its own. The owner has to ask for it, and it stays available only while nobody else is paying to sleep there. Guests who do pay also owe lodging taxes, and those rates depend on which county the dock sits in. Winston County's new tax took effect this fall.
The two numbers that set an Alabama property tax bill
Alabama doesn't tax a house on its full appraised value. It first multiplies the appraisal by a class rate to get an assessed value, and the millage applies to that smaller figure. The Alabama Department of Revenue lays out the formula as appraised value times class rate.
Two classes matter for a lake home. Under Code of Alabama § 40-8-1, Class II covers "All property not otherwise classified, 20 percent," and Class III covers agricultural, forest and residential property at 10 percent. The statute defines residential property narrowly: "Real property, used by the owner thereof exclusively as the owner's single-family dwelling."
The definition says nothing about the house being your main home. What it requires is exclusive use by the owner. Cullman County says so directly: "any single family dwelling used exclusively by its owners may be assessed at the owner-occupied tax rate (class 3 property). Often called a 'second home exemption,' this assessment will be based on ownership and use at the start of the applicable tax year."
So a Birmingham family's Saturday-and-Sunday house on a Cullman County cove can sit in the same 10% class as the year-round home next door. It gets there only if the owner tells the county it belongs there, because the default is the 20% class.
What the gap looks like on Smith Lake millage
Smith Lake reaches into Cullman, Walker and Winston counties, and each one has its own millage. The Department of Revenue's 2025 millage table, dated October 2025 and the most recent one the department lists, gives these totals for unincorporated areas in the county school districts shown:
- Cullman County, District 1: 26.0 mills, made up of 6.5 state, 9.5 county and 10.0 school
- Walker County, Districts 1 and 2: 25.5 mills, made up of 6.5 state, 9.0 county and 10.0 school
- Winston County, Districts 1 and 2: 28.0 mills, made up of 6.5 state, 9.5 county and 12.0 school
Now run a hypothetical lake house appraised at $500,000 through both classes at those 2025 rates. These are round illustration numbers. They leave out any homestead exemption and any added city millage, and every parcel's rate depends on its own taxing district.
| Hypothetical $500,000 appraisal, 2025 millage | Class III, 10% | Class II, 20% |
|---|---|---|
| Cullman County, 26.0 mills | $1,300 | $2,600 |
| Walker County, 25.5 mills | $1,275 | $2,550 |
| Winston County, 28.0 mills | $1,400 | $2,800 |
Across the three counties, the bills in each column land within about $125 of one another, while switching classes adds between $1,275 and $1,400. When buyers compare a Winston County cove with a Walker County point, they usually look at millage. On these numbers the class matters about ten times as much, and it depends on paperwork and on how the house is used, not on location.
October 1 is the snapshot, December 31 is the deadline
Class and exemptions follow a calendar. Cullman County bases homestead status on whether the owner occupies the home as a primary residence on October 1, the first day of the tax year. It says exemptions should be applied for before December 31, and it states plainly that a homestead exemption "is not automatic." The second-home assessment works on the same idea of "ownership and use at the start of the applicable tax year," and Cullman lets owners file it online through the county's property portal or at any Revenue Commission office.
The Walker County Revenue Commissioner uses the same timing for exemptions, with applications due before December 31 based on status as of October 1. Walker's page limits its homestead exemptions to primary residences and doesn't spell out a second-home procedure like Cullman's. Owners on the Walker or Winston side of the lake should call the revenue commissioner's office and ask how a second home used only by the owner gets assessed.
These are two separate tools, and buyers mix them up all the time. The homestead exemption is for the house you live in. Cullman's H1 exemption applies to Alabama residents who own and occupy a single-family residence as their primary residence and use it for nothing else. The second-home assessment covers the lake house you don't live in full-time but use only yourself. An out-of-state weekender can't claim a homestead on Smith Lake, but the 10% class may still be open to them.
This post goes up in late October. The tax year started October 1, and the December 31 date is about two months away. That's the stretch when owners who closed this year should check how their parcel is assessed.
Rental use points the house toward the higher class
The same exclusive-use language that lets a second home into Class III can also take it out. As the statute is written, a house rented to someone else, whether for a weekend or a season, isn't used by the owner exclusively as a single-family dwelling. Property outside the residential definition falls under "All property not otherwise classified," which is Class II at 20 percent. Cullman County also says it treats properties as non-owner-occupied unless the owner assesses them otherwise, and that owners are responsible for reporting how a property is used.
That changes the math for a buyer who plans to cover costs by listing the lake house a few weekends each summer. On the hypothetical table above, the property tax gap alone runs from $1,275 to $1,400 a year, depending on the county. Any rental income has to cover that before it pays for anything else.
Builders and lot investors run into a related rule. The statute lets a licensed home builder keep a finished single-family home and its developed lot in the residential class for up to 24 months from when the builder applies for that classification, until the home is sold or put to another use.
This fall, the county line also sets the cost of a rental night
The class change from renting works the same way in all three counties, doubling the assessment ratio. The taxes a guest pays vary more, and both Winston and Walker counties have a lodgings entry dated October 1, 2026.
Alabama's lodgings tax applies to stays shorter than 180 continuous days. When a booking platform remits all the state and local lodgings tax on a stay, the host doesn't need to open those tax accounts for those platform bookings. Local taxes are layered on top of the state rate, and the totals now look different from one side of the water to the other.
Winston County. Voters approved the new tax 66% to 34% in the June 16 runoff, ABC 33/40 reported. It sets an 8% lodging tax and a $5 nightly fire protection fee on "short-term rentals, hotels, cabins and other lodging accommodations throughout the county." The bill text, printed as a legal notice in the Northwest Alabamian, names short-term rentals in its list of covered lodging and says the business furnishing the accommodations collects the tax from the guest at the time of payment. The notice lists October 1, 2026 as the effective date if voters approved the measure. The Northwest Alabamian's ballot coverage described the proceeds as 55% for roads and bridges, 20% for the sheriff, 15% for tourism development and 10% for existing jail and judicial-building debt, with the $5 fee divided equally among the county's volunteer fire departments. The state lodgings rate in Winston County is 5%.
Walker County. The Department of Revenue's local lodgings rate report, generated October 2, 2026, lists a 9% Walker County lodgings tax with an active date of October 1, 2026. That entry is coded as a change in how the tax is administered, not as a new tax. The state rate in Walker County is 4%, so a stay there totals 13% before any city tax.
Cullman County. The same report lists a 5% county lodgings tax and a 5% state rate.
On a $400 rental night, Winston County's 8% plus the flat $5 fee adds $37 at the county level, Walker County's 9% adds $36 and Cullman County's 5% adds $20. Those charges apply to the night that's booked. The property class is set from ownership and use at the start of the tax year, so an owner who starts renting partway through the year should ask the revenue commissioner when the change in use shows up on the assessment.
We share this as general information about how these rules are written, not as legal, tax or financial advice. Your county revenue commissioner and your own tax professional are the right people to confirm how any specific property should be assessed or taxed.
Questions we hear about second-home taxes on the lake
Does the county switch a second home to the lower rate automatically? Not in Cullman County. The revenue commissioner says properties are considered non-owner-occupied unless the owner assesses otherwise, and that second homes can be assessed online or in person. Walker and Winston county owners should ask their own offices how it works there.
Can I get a homestead exemption on a lake house if my main home is somewhere else? Homestead exemptions in Cullman and Walker counties are for primary residences only, based on occupancy on October 1. The Class III second-home assessment is a separate thing from a homestead exemption.
Does a long-term tenant keep the house in the residential class? The statute's residential class requires use "by the owner thereof exclusively as the owner's single-family dwelling," so any tenant, short-term or long-term, puts that use test in question. Stays of 180 continuous days or more are exempt from the lodgings tax.
