Pickwick Lake crosses three states before it ever reaches open water again: Alabama at its southern arm, Mississippi along its western shore, Tennessee everywhere north of the dam. Buyers comparing a lot in Iuka against a lot in Counce almost always start with the same assumption, that the Mississippi side is the cheaper state to own property in. Tennessee gets the low-tax reputation nationally, but Mississippi has its own reputation among Southern retirees as the place where a dollar goes further. Put those two ideas side by side at Pickwick and most buyers land on the same guess: Mississippi wins on taxes, Tennessee wins on lifestyle branding.
The property tax bill runs the other way.
The Line Item That Actually Flips
Hardin County, Tennessee, where Savannah, Counce, and Pickwick Dam all sit, carries a median effective property tax rate of about 0.44%. Cross the water into Tishomingo County, Mississippi, and that rate climbs to a county median of 0.94%, with Iuka posting the highest effective rate in the county at 1.16%. Glen, on the other end of the same county, sits at 0.73%. Even the low end of Tishomingo County runs higher than the Tennessee side.
Run that through a real number. A $400,000 lake home taxed at Hardin County's 0.44% owes roughly $1,760 a year in property tax. The same home taxed at Iuka's 1.16% owes closer to $4,640. That's about $2,880 more every year, before insurance, before HOA dues if the property sits in a gated section, before anything else changes hands.
| Hardin County, TN (Savannah, Counce, Pickwick Dam) | Tishomingo County, MS (Iuka) | |
|---|---|---|
| Median effective property tax rate | ~0.44% | ~0.94%, up to 1.16% in Iuka |
| State income tax | None | 4.0% flat on income above $10,000/individual, declining |
| Grocery sales tax | 4% state rate | 5% state rate as of July 2025 |
| Retirement income (Social Security, pensions, 401k, IRA) | Not taxed | Not taxed |
That last row matters because it's the one place both sides already agree. Neither state touches Social Security, pensions, or retirement account withdrawals. The tax conversation at Pickwick isn't really about retirement income at all. It's about everything else.
Mississippi Is Closing the Gap, It Just Isn't There Yet
Tennessee finished eliminating its state income tax years ago. Mississippi is still walking toward the same destination, but the walk started on a real calendar. Governor Tate Reeves signed House Bill 1 on March 27, 2025, putting the state's income tax on a legislated phase-down: 4.4% in 2025, 4.0% in 2026, dropping another quarter point most years after that until it reaches 3% around 2030, with a path to zero if state revenue targets hold. The same bill cut Mississippi's grocery sales tax from 7% to 5%, effective July 1, 2025, and raised the state gas tax to help cover the difference.
None of that changes what a retiree pays today, since Mississippi already exempts retirement income entirely. It matters more for anyone still earning a paycheck, running a business, or holding investments while living on the Mississippi side. That income tax bill is getting smaller every year, but it hasn't hit zero yet, and the schedule depends partly on the state hitting its own revenue benchmarks.
The Senior Exemption Nobody Mentions Until You Turn 65
The property tax gap between the two sides isn't fixed for every buyer. Mississippi's standard homestead exemption trims up to $300 off a tax bill for owners under 65, which barely moves the number on a $400,000 lake home. The exemption for owners 65 and older is a different animal entirely: it shields the first $12,500 of assessed value from all property tax, which works out to removing the first $125,000 of actual market value from taxation, since Mississippi assesses residential property at a fraction of true value.
For a retired couple buying in Iuka, that exemption can close most of the gap with Hardin County, sometimes all of it, depending on the home's value. The catch is that Mississippi's homestead exemption isn't automatic. Owners have to file the application with the county tax assessor, and the office handling that paperwork for Tishomingo County sits in Iuka itself. Miss the filing window and the higher rate applies for that year regardless of age.
Tennessee runs its own property tax relief programs for seniors and disabled homeowners through the county trustee's office, with different eligibility rules and different dollar amounts. The two states aren't offering the same benefit, so a side-by-side comparison only means something once you've confirmed which exemptions actually apply to the specific buyer, not the county average.
What Changes If You're Selling Instead of Buying
The tax difference between the two sides shows up again at the exit, not just during ownership. Mississippi taxes capital gains as ordinary income, which means gains above the state's exemption threshold get taxed at that same declining flat rate, currently 4.0% for 2026. Tennessee has no state income tax at all, so a gain on the sale of land or an investment property carries no state-level tax exposure beyond whatever the IRS collects federally.
That distinction matters most for the landowner and investor working the Counce, Savannah, or Iuka markets, someone selling a buildable lot or a rental property rather than a primary residence eligible for either state's homestead protections. The federal capital gains treatment is identical wherever the property sits. The state-level piece isn't, and it depends on which side of the water the seller calls home for tax purposes, not necessarily which side the property is on.
The Smaller Costs That Still Add Up
A few other differences are worth knowing even though none of them carries the weight of the property tax gap. Mississippi's grocery tax sits at 5% as of mid-2025, down from 7%. Tennessee taxes groceries at a separate reduced state rate of 4%, plus whatever local option tax the county adds on top. Neither state exempts groceries outright, which puts both sides of Pickwick in a smaller group of states that tax food at all.
Vehicle and boat purchases follow their own rules on each side, and the math doesn't always match popular assumption there either. Tennessee applies its 7% state rate to the full purchase price of a boat, but the local option portion of that tax only applies to the first $1,600 of value, which means the local tax on a $150,000 boat costs about the same in dollars as the local tax on a $10,000 fishing boat. Mississippi taxes boats at a flat 7% with no such cap. On a modest boat the two states land close to even. On a larger one, Tennessee's structure tends to work slightly better for the buyer.
Before You Write the Offer
None of this changes where the fish bite better or which side has the dock you actually want. It does change what a serious comparison should include before an offer goes in.
- Ask the seller's agent for the current parcel's assessed value and confirm which county's millage rate applies, not just the county-wide median.
- If either buyer is 65 or older, ask specifically whether the Mississippi senior homestead exemption or Tennessee's own relief program would apply, and get the filing deadline in writing.
- If the property is an investment or a lot rather than a primary residence, ask a tax professional how the sale would be taxed at the state level based on residency, not property location.
- Don't assume last year's rate holds. Mississippi's income and grocery tax rates are both mid-change under HB1's schedule, and Tishomingo County's assessment notices go out each spring.
None of that arithmetic is a substitute for walking a specific property with someone who knows which side of a subdivision line falls in which county, which is common near the water at Pickwick, and who can put you in front of the right assessor's office before the deadline rather than after. That's the kind of groundwork Crye-Leike Pickwick does as a matter of course, with brokers licensed across Tennessee, Mississippi, and Alabama who can walk a buyer through both sides of this particular state line before an offer, not after a surprise tax bill. If you're weighing a lot in Iuka against one in Counce or Savannah, reach out and we'll run the actual numbers on the specific parcel, not just the county average.
