West Utah County vs. Southwest Salt Lake County: New-Construction Property Taxes
For the west-side commuter comparison, new single-family construction in Saratoga Springs and Eagle Mountain is taxed at about 0.516% of assessed value, with a median annual bill near $2,648. The southwest Salt Lake County production cities – Herriman, South Jordan, West Jordan, Riverton, Bluffdale – come in at about 0.547%, with a median bill near $3,660. A Saratoga Springs or Eagle Mountain buyer pays a lower tax rate and a lower price than a Herriman or Daybreak buyer, so property tax reinforces the price advantage the west Utah County side already has. Over a seven-year hold the tax difference alone is roughly $7,000. Effective rates are from tax year 2024 assessor records on completed new-construction homes (2023-2025 builds); a brand-new 2026 home is assessed on land only for its first year or two, so your first tax bill will look tiny and then jump to roughly the rate times what you paid once the county adds the house to the roll. Figures are as of September 2026 and move with annual valuations and mill rates. All rates assume the primary-residence exemption; a rental or second home pays roughly 1.8 times as much.
