## 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.
