At its October 13, 2026 meeting, Thompson's Station's mayor put the town's finances in two figures. The town collects about $800,000 a year in property tax and about $3.2 million in commercial sales tax. That is roughly four dollars from retail for every dollar from homeowners. The same meeting showed what that ratio means in practice. The board voted 4–0 on a deal that has a shopping destination's developer widen Lewisburg Pike before a single store opens.
For buyers comparing southern Williamson County towns, this changes how to read a Thompson's Station address. The low property tax and the road fixes come from the same source. Because of that, the timeline for relief on US 431 and Highway 31 now depends on commercial milestones as much as on any state road plan.
The Town's Budget Leans on Registers, Not Rooftops
Thompson's Station doesn't bill homeowners directly. According to the Town's property tax page, residents pay through the Williamson County Trustee. On the revenue side, the October meeting record gives these figures:
| Revenue line | Figure cited at the Oct. 13, 2026 BOMA meeting |
|---|---|
| Property tax collected per year | About $800,000 |
| Commercial sales tax collected per year | About $3.2 million |
| FY2027 local-option sales tax budget | $3.1 million |
| Town's projected first-year half-share of new Sagefield sales tax | About $2.9 million |
| Estimated yearly cost of a seven-person police department | $1.3 million |
The mayor named the businesses carrying that load. Kroger is the town's top sales-tax generator, followed by FirstBank Amphitheater, the businesses at Tollgate and a few others. The town also maintains its own roads, including Thompson's Station Road East and West, Critz Lane and School Street, and it pays staff from the same budget.
The fourth row of the table matters most. In its first year, the town's half of Sagefield's projected sales tax alone would come close to everything the town now budgets from local-option sales tax.
Why That Math Pushes Road Costs Onto Developers
A town that raises little from property tax can't easily borrow tens of millions for road work. Alderman Bob Whitmer explained where the board stands in the October 13 meeting minutes:
"We've talked about our property taxes, which are extremely low, very low. I want to keep it that way... So, we must leverage our commercial base."
He also called the town's two interstate access points an asset for drawing commercial revenue. Vice Mayor Shaun Alexander said the board had updated its traffic standards so that developers "have to improve the situation that they're building in." He added that those standards earned the town a planning award.
The town has limited power to block commercial projects. According to the Town's October 13 staff report, the 100-acre Sagefield site at 1733 Lewisburg Pike has been zoned commercial since 2008, and every use Simon proposed is allowed by right in that district. What the town can control is the order things happen in and who pays for the roads.
How the Sagefield Deal Works, Step by Step
Simon Property Group announced Sagefield on November 4, 2025. The plan combines boutique retail, restaurants, entertainment, an organic market, wellness uses and a hotel. Simon's partner is AJ Capital Partners, with Sam Fox's Author & Edit Hospitality named for the hotel. In June 2026 the Planning Commission approved a site plan for 16 buildings and about 496,366 square feet. The financing approved in October runs in this order:
- The developer builds first. Simon provides about $61 million in public-facing improvements. Lewisburg Pike road work and utility relocations make up about 80% of that total.
- The roads get widened. Lewisburg Pike goes from two lanes to four with turn lanes. The work also relocates utilities, adds a wastewater connecting line and increases capacity at the I-840 westbound off-ramp.
- The town takes ownership before anything opens. All improvements must be finished before Sagefield opens. The vice mayor described this as completing the work and dedicating it to the town, under warranty, before any doors open.
- Repayment comes only from Sagefield's own sales tax. The new local sales tax from the project is split 50/50 between the town and repayment. Principal is capped at $42 million, about 70% of the $61 million, with interest capped at 8% and a payback period of no more than 29 years. The mayor said no other commercial sales tax in town goes toward that repayment.
- Progress is reported every quarter. Monitoring with Simon is reported quarterly to the Economic Development and Infrastructure Acceleration Board and to the Board of Mayor and Aldermen.
The deal also includes donated land for a town police department, which the mayor said has long been on the board's list.
Town staff said Lewisburg Pike was not in TDOT's 10-year plan, and they described the agreement as moving the improvements up by at least a decade. The project has drawn local concerns. WKRN reported in February 2025 that some residents raised traffic, road capacity and rural character, and that some preferred a grocery store or another community-serving use.
For timing, the Williamson Herald reported that the developer planned to break ground in late 2026 and open in fall 2028. A Simon representative said the road widening would come before site construction. Under this agreement, a wider Lewisburg Pike is a precondition for Sagefield's opening day.
Highway 31 Runs on a Different Clock
On the west side of town, Columbia Pike is a TDOT project, and the town put up local money to speed it up. According to the Town's project page, the board agreed in late 2024 to include $15 million in local funds in its Statewide Partnership Program request. In April 2025, TDOT accepted that request, which moved preliminary engineering on the four-lane widening from 2029 to 2026. The planned cross-section includes a landscaped median along parts of the corridor. WKRN reported that the corridor had previously been expected to finish near the end of TDOT's plan in 2032.
Commercial growth on this corridor is also tied to road work. The Costco planned within Hatcher Cotton, at 5001 Merchant Lane off 4521 Columbia Pike, is a 168,244-square-foot warehouse with a 32-pump fuel station on a 24.64-acre site. It went before the Planning Commission on October 27, 2026, as Williamson Source reported. Staff recommended approval with 13 contingencies. One requires the Hatcher Cotton developer to sign the Highway 31 Corridor Improvement Plan Agreement before any building permit is issued. That agreement sets the development's share of road and infrastructure work with TDOT, the town and other projects along the corridor. The plan also includes 415 trees, more than the 308 required, along with a greenway extension.
Both corridors follow the same rule. A commercial project of any size gets its approvals only after it commits to pay for part of the road it will add traffic to.
What This Means When You're Comparing Addresses
A buyer weighing a home near Lewisburg Pike and another near Columbia Pike is weighing two different paths to traffic relief:
- Near Lewisburg Pike and the I-840 ramp: the widening is privately funded and has to be finished before Sagefield can open. The milestones to watch are Simon's construction start and the quarterly reports to the board.
- Near Columbia Pike: the widening is a state project that the town committed $15 million to speed up. Commercial projects like the Costco at Hatcher Cotton are required to coordinate their share of the work.
- On town-maintained roads like Critz Lane and Thompson's Station Road: upkeep comes from the general budget. That budget gets most of its revenue from sales tax, much more than from property tax.
The town's own leaders said they intend to keep the property tax low and grow the commercial base instead. In practice, a growing share of town services, from road maintenance to a future police department, depends on how well local retail performs.
Quick Answers
Does Sagefield's road debt come out of the town's general fund? Town staff told the board the agreement has no impact on the current or future general fund. Repayment comes only from new local sales tax generated at Sagefield.
Could the town have rejected Sagefield outright? The Town's staff report says the site has been zoned commercial since 2008 and the proposed uses are allowed by right. Its site plan became vested when the Planning Commission approved it in June 2026.
Who do Thompson's Station homeowners pay property tax to? The Williamson County Trustee, according to the Town.
