Hi . what can be an issue, if on checkout page i have subtotal price, shipping price, tax, and total being shown up, but when i click to process order it is not charging the tax.
i am running 1.3.9h all tax settings are set (most likely correctly if i see it shown up on a checkout page, that it is going to charge me state tax, but actually it doesn't).

Store settings:
Country United States
Zone Arizona
Basis of product tax Billing


Zone definition
Zone Name Arizona
Zone Definition Arizona local sales tax zone
Tax Classes Taxable goods
Tax Rates: Taxable Goods Arizona 9.3% AZ TAX 9.3%


Any help would be apretiated. tnx.
