Why is Utah sales tax overcharging on Shopify?

Payments + Shipping & Fulfilment

Topic summary

Utah sales tax calculation is suddenly incorrect on Shopify. Previously working “flawlessly,” it began last week to apply Salt Lake County and Magna municipal taxes to all Utah shipping addresses.

  • Configuration is reported as set up correctly.
  • Taxes are being applied based on Salt Lake County and Magna jurisdictions even when the destination address is outside those areas, causing overcharges.

No alternative viewpoints or fixes were offered. The poster requested guidance from Shopify support. Status: unresolved/ongoing; key question is why jurisdiction-based tax is misapplied across Utah.

Utah taxes have been working flawlessly until last week :sad_but_relieved_face: They are setup correctly but they are taxing all shipping locations in Utah with Salt Lake County and Magna Municipal tax even when the address is not located in those jurisdictions. Shopify is basically overcharging for Utah sales tax now.

@Shopify_77 please advice.
