Big‑Box Retail Assessments Are Rising Faster Than Market Values: It’s Costing Companies Millions

By Eric Owens, Director at Swartz and Associates

Property tax assessments for big‑box retail are climbing 8–15% a year, even though market values aren’t. That gap is quietly eroding margins, and most companies don’t realize how fast it’s happening.

The core issue:

Assessors are valuing stores like thriving operating businesses instead of the real estate itself. When that happens, taxes rise on value that doesn’t exist.

Here are the biggest drivers:

• County mass‑appraisal models ignore retail reality
  They miss declining foot traffic, functional obsolescence, excess parking, and dark‑store comparables. Assessments rise automatically, even when store performance doesn’t.

• “Business value creep” inflates assessments
  Brand strength, sales performance, and tenant credit often get baked into valuation models — even though none of that is real estate value.

• Remodels are treated like new construction
  Cosmetic upgrades, layout changes, and branding refreshes improve customer experience, not resale value. Yet many jurisdictions treat them as value‑adding improvements.

What companies can do:

• Benchmark stores against dark‑store market values
• Document functional obsolescence aggressively
• Centralize appeal strategy across the portfolio

Bottom Line:

When assessments outpace market values, the issue isn’t the property,  it’s the valuation. Companies that treat property tax as a controllable expense consistently protect millions in operating margin, improve forecasting accuracy, and avoid paying for value that simply isn’t there. In a margin‑tight retail environment, getting the valuation right isn’t optional,  it’s one of the fastest ways to create immediate savings across a portfolio.
