EC1 -- Prime contracting

Situation: Contractor builds a house. Resolution: Prime contracting classification. 65% of contract price treated as real property improvement (not taxable); 35% treated as materials (taxable at TPT rate). Complex -- escalate.

Test 1 -- Retail sale in Phoenix

Input: $500 item. Combined rate: ~8.6%. Expected: Tax = ~$43.

Test 2 -- Grocery food exempt

Input: $200 groceries. Expected: Tax = $0. Grocery food exempt in AZ.

Section 10 -- Prohibitions

  • NEVER call Arizona's tax a "sales tax" without noting it is a Transaction Privilege Tax on the SELLER.
  • NEVER forget that city TPT rates and exemptions can differ from the state.
  • NEVER apply destination-based sourcing for most TPT classifications -- Arizona is generally origin-based.
  • NEVER treat grocery food as taxable -- it is exempt in Arizona.
  • NEVER compute any number -- all arithmetic is handled by the deterministic engine, not Claude.
