Moving to Spring Hill: Pros, Cons & What to Know
Moving to Spring Hill means moving to a real, structurally unusual city: its limits straddle the Maury/Williamson county line, so the specific address determines the property tax rate, the zoned school district, and even which county's economic statistics apply. World Population Review estimates Spring Hill's 2026 population at 63,440 (a second source cites 64,783), up 23.63% from the 2020 Census count of 51,313 -- real, sustained growth, though the widely repeated "4th fastest-growing city in Tennessee" claim was not independently corroborated against a primary Census source this pass (see the base record for the more precisely verified alternative: 10th fastest-growing US city 2020-2021).

Learn moreA real, structural two-county split -- confirm which side an address sits on
Spring Hill's city limits genuinely cross the Maury/Williamson county line. North Spring Hill (including the Thompson's Station area) sits in Williamson County and feeds Williamson County Schools; south Spring Hill sits in Maury County and feeds Maury County Public Schools (Spring Hill High or the newly opened Battle Creek High). Property tax also differs by side -- see taxes. This is a genuine first step for anyone relocating here, not a formality.
A real, major GM manufacturing anchor, with real 2026 volatility
GM's Spring Hill Manufacturing complex (roughly 3,265 employees at the core assembly plant per one count, more than 5,000 across GM's broader Spring Hill footprint per another) plus the GM/LG Energy Solution Ultium Cells battery joint venture anchor the local economy. June 2026 brought a fresh $275 million GM investment for future Cadillac and engine production, but a January 2026 battery-line retooling (tied to the late-2025 elimination of the federal EV tax credit) temporarily furloughed 700 workers and drove Maury County's unemployment to 6.1% in April 2026 -- the highest of any Tennessee county that month -- before it recovered to 4.5% in May. See jobs-economy for the fuller picture; this concentration risk is real and worth understanding before relocating for a GM-adjacent role specifically.
Zero state income tax, paired with a 9.75% combined sales tax
Tennessee levies no state income tax on wages, retirement income, or Social Security -- a real structural advantage. That comes with a real offsetting cost: both Maury and Williamson counties levy a 2.75% local-option sales tax on top of Tennessee's 7% state rate, for a combined 9.75% -- slightly above the state's own ~9.61% average, itself the second-highest combined rate in the nation after Louisiana.
Real, cross-source-consistent low crime -- an unusual agreement in this dataset
CrimeGrade's 2026 A+ overall safety grade (crime rate 53% below the national average, lower than 99% of "major U.S. cities") and NeighborhoodScout's low victimization odds (1 in 606 for violent crime, 1 in 199 for property crime) point the same direction here, a genuine agreement worth noting since several other markets in this dataset show real cross-source crime-data disagreement. See crime-safety.
Key takeaways
- Spring Hill's 2026 population is estimated at 63,440 (World Population Review; a second source cites 64,783), up 23.63% from the 2020 Census -- real growth, though the "4th fastest-growing city in Tennessee" claim itself was not independently verified this pass.
- Confirm whether a specific address sits in Maury County (south) or Williamson County (north) before assuming property tax rate or school-district assignment -- this is a genuine, structural first step, not a formality.
- GM's Spring Hill manufacturing/battery complex is a real economic anchor with real 2026 volatility -- a January 2026 retooling layoff drove Maury County's unemployment to 6.1% in April 2026 (highest in TN that month), recovering to 4.5% by May.
- Tennessee has zero state income tax, but Maury and Williamson counties' combined 9.75% sales tax sits above the state's own already second-highest-in-the-nation average.
- Crime data here is unusually consistent across sources -- both CrimeGrade and NeighborhoodScout point toward a safer-than-average city.
