Understanding Sales Tax in E-commerce

What is Sales Tax?

Sales tax is a mandatory financial obligation for businesses selling goods or services. Unlike income tax, which is levied on earnings, sales tax is a direct charge on consumer purchases, with rates determined by state, county, and sometimes city regulations.

Sales Tax Calculation Basics

Basic Formula:

Sales Tax = Purchase Price × Tax Rate

Example:

Product Price: $100

Local Sales Tax Rate: 7.5%

Sales Tax = $100 × 0.075 = $7.50

Total Price: $107.50

E-commerce Sales Tax Considerations

  • Nexus Requirements: Physical or economic presence in a state triggers tax collection obligations
  • Multi-State Complexity: Different rates and rules across jurisdictions
  • Digital Product Variations: Tax treatment differs for digital vs. physical goods
  • Marketplace Facilitator Laws: Some platforms collect and remit taxes on seller's behalf
