A disabled veteran family stationed at Fort Campbell starts comparing homes on both sides of the state line, and somewhere in that research turns up a specific number: Kentucky will exempt up to $240,000 of a 100% disabled veteran's home value in 2026, climbing to $400,000 by 2030. It sounds decisive. It would be decisive, if it were true.
It isn't. That provision comes from Kentucky House Bill 639, introduced during the 2025 regular session of the Kentucky General Assembly. It went to the Appropriations and Revenue Committee in February 2025 and never came back out. Kentucky's own legislative record lists one final status for the bill: Introduced, then Dead. It was never enacted. Several military benefits sites and mortgage blogs are still describing the $240,000 exemption as current law in 2026, which means anyone using that figure to run the numbers on a Cadiz purchase is working from a bill that doesn't exist.
That single correction matters, but it's not the whole story. Even once you strip out the phantom exemption, the property tax comparison between Trigg County, Kentucky and Montgomery County, Tennessee still isn't the simple "Kentucky is cheaper" math most people assume. The two states measure the tax differently before they even apply a rate, and that difference changes which side of the line actually costs less depending on the home's value, whether it sits inside Clarksville's city limits, and whether the buyer qualifies for the KY exemption that does exist.
What Kentucky Actually Offers A Disabled Veteran
Without HB 639, the only property tax relief a disabled veteran gets in Kentucky is the same relief available to any Kentucky homeowner who is 65 or older or classified as totally disabled. It's a flat $49,100 deducted from the assessed value of a primary residence for the 2025-2026 assessment years, filed on Form 62A350 with the county Property Valuation Administrator, known locally as the PVA. Trigg County's PVA office sits in Cadiz. Veteran status alone does not qualify anyone for this. The homeowner has to independently meet the age or disability standard, and a service-connected total disability rating from the VA satisfies that standard, but a 50% or 70% rating does not.
The Rate You're Comparing Isn't Measuring The Same Thing
Tennessee assesses residential property at 25% of its appraised value before applying any tax rate. A $280,000 home in Montgomery County gets taxed as if it were worth $70,000. Kentucky assesses much closer to full fair market value, then subtracts flat-dollar exemptions like the $49,100 homestead deduction. A $267,500 home in Trigg County gets taxed close to its full sale price, minus whatever exemption applies.
That single difference is why comparing the two states' tax rates side by side, without accounting for what each rate is applied to, produces a misleading answer.
| Tennessee (Montgomery County) | Kentucky (Trigg County) | |
|---|---|---|
| Assessment basis | 25% of appraised value | Near full fair market value |
| 2026 county rate | $2.10 per $100 assessed | Varies; reported effective rates range roughly 0.54% to 0.95% |
| Clarksville city add-on | $1.01 per $100 assessed (inside city limits) | Not applicable outside Kentucky |
| Flat exemption available | $175,000 of value, disabled veterans only, via reimbursement | $49,100 of assessed value, 65+ or totally disabled, any homeowner |
On a $280,200 home, which is the median home value across Montgomery County according to the Census Bureau's most recent five-year estimate, that 25% assessment ratio puts the taxable base at $70,050. At the county's $2.10 rate, that's roughly $1,471 a year before any city tax. Inside Clarksville's city limits, add the $1.01 municipal rate on that same assessed base, and the bill runs closer to $2,179.
Kentucky's Own Numbers Don't Agree With Each Other
Here's where the Trigg County side gets genuinely confusing, and it's worth sitting with rather than smoothing over. Different third-party property tax trackers report Trigg County's effective rate anywhere from 0.54% to 0.95%, a spread wide enough to change the answer. Run that range against a $267,500 home, chosen here to sit close to the Tennessee example above so the two states compare on similar footing, and the estimate swings from roughly $1,445 to $2,541 a year on the identical house depending on which published figure you trust.
The honest answer is that no single percentage should be quoted with confidence until it's checked against the Trigg County PVA for the specific parcel. If a buyer does qualify for the $49,100 homestead exemption, that same $267,500 home drops to roughly $218,400 in taxable value, which at Kentucky's statewide average effective rate of about 0.75% works out closer to $1,638 a year, landing right in between the low and high estimates for the unadjusted bill.
Tennessee's Veteran Benefit Isn't An Exemption, It's A Refund
Tennessee Code Annotated § 67-5-704 gives qualifying 100% permanent and total disabled veterans state-funded relief on property tax, but the mechanics catch people off guard. It's a reimbursement, not an exemption. The homeowner still receives the full tax bill and still pays it. In the first year, that means paying the entire amount, then submitting the paid receipt along with the application to the county before getting a refund back from the state. In every year after that, the process shifts: the homeowner gets a voucher showing what the state is covering, and pays only the remaining balance. For a family moving on PCS orders and already managing deposit money, movers, and a new mortgage, that first-year full-payment requirement is a real cash-flow gap that nobody budgets for if they assume "exemption" means the bill simply disappears.
It also doesn't disappear at any home value above the cap. The relief covers tax on only the first $175,000 of a home's market value. On that same $280,200 median home, the portion of value above $175,000, which is $105,200, still gets taxed at the normal rate. Worked through the 25% assessment ratio, that remaining slice comes to roughly $552 a year in county tax alone, or about $818 if the home sits inside Clarksville and picks up the city rate too. A fully qualifying disabled veteran in Tennessee, buying at the current median home value, is not paying zero property tax. They're paying tax on everything above $175,000.
Where To File, And What Each Office Actually Does
- Kentucky homestead exemption: File Form 62A350 with the Trigg County PVA office in Cadiz. Applies once; no annual refiling required for veterans with a permanent total disability rating.
- Kentucky veteran-specific exemption: Does not currently exist as law. HB 639 proposed it and died in committee.
- Tennessee disabled veteran relief: Apply through the Montgomery County Trustee's office at Veterans Plaza on Pageant Lane in Clarksville, not the assessor. First-year applicants pay in full and submit a receipt; later years use a voucher.
What This Actually Means For A Buyer Choosing Between The Two
None of this settles the question in one direction. A Kentucky buyer who qualifies for the $49,100 exemption and lands near the low end of Trigg County's reported rate range comes out ahead of a comparable Clarksville home inside city limits. The same Kentucky buyer at the high end of that rate range, without the exemption, can land above the Tennessee county-only number. A Tennessee veteran counting on the state relief to zero out their bill needs to know it only covers the first $175,000 of value and arrives as a refund, not an automatic reduction, in year one.
The right comparison isn't a rate. It's the specific home's assessed value, the specific exemptions that specific buyer actually qualifies for, and which office they need to file with before closing, not after.
If you're weighing a home search that crosses this line, whether that's Cadiz on the Kentucky side or a Clarksville neighborhood on the Tennessee side, this is exactly the kind of math worth running before you write an offer, not after.

A Few Questions Worth Asking Before You File
Does a VA disability rating alone qualify me for Kentucky's homestead exemption? No. Kentucky requires the homeowner to be classified as totally disabled or age 65 or older. A service-connected total disability rating from the VA satisfies that standard, but a partial rating does not, regardless of veteran status.
If HB 639 gets reintroduced and passes later, would it apply retroactively? There's no way to answer that until a bill actually passes. As of now, it isn't law, so any exemption amount tied to it should be treated as unavailable until the Kentucky General Assembly enacts something and the Department of Revenue publishes guidance.
Is Tennessee's disabled veteran benefit the same as a full property tax exemption? No. It's a state-funded reimbursement on the tax owed for the first $175,000 of a home's market value, applied for through the county trustee. Value above that threshold is still taxed at the normal county and, if applicable, city rate.
