Transaction Privilege (TPT) & Use Tax

Severance Tax (Mining/Timber)

What is Arizona Transaction Privilege Tax (TPT)?

The Arizona Transaction Privilege Tax (TPT) is widely misunderstood as a simple sales tax, but legally, it is distinct. Unlike a traditional sales tax levied on the consumer, TPT is a tax on the privilege of doing business in the state of Arizona. While the burden is typically passed on to the customer, the legal liability for payment remains with the vendor.

This calculator also handles Use Tax (applied to out-of-state purchases used within Arizona) and Severance Tax, which applies to the extraction of natural resources like metalliferous minerals and timber. Understanding the interplay between state, county, and city rates is critical for accurate compliance.

Key Takeaway: TPT rates are a combination of State, County, and City taxes. A business in Phoenix pays a different total rate than a business in Scottsdale due to varying municipal add-ons.

Arizona TPT and Severance Tax Formulas

Calculating your tax liability involves determining your “Net Taxable Base” and applying the stratified tax rates. Below is the breakdown of the mathematics used in our calculator.

1. Transaction Privilege Tax (TPT) Formula

The general formula for TPT is:

Total TPT = (Gross Receipts – Deductions) × (State Rate + County Rate + City Rate)

Variables used in TPT calculation

Variable	Meaning	Typical Value
Gross Receipts	Total income from business activities	Variable
Deductions	Statutory exclusions (e.g., resale)	Variable
State Rate	Base AZ tax rate	5.6%
County/City Rate	Local jurisdiction surcharges	0.5% – 4.0%

2. Severance Tax Formula

Severance tax is calculated on the value of resources extracted from Arizona soil.

Severance Tax = Net Severance Base × Severance Rate

For metalliferous mining, the standard rate is typically 2.5%. For timber, it is often 1.5%.

Practical Examples: Calculating Your Liability

Example 1: Retail Business in Phoenix

A furniture store in Phoenix has gross sales of $100,000 for the month with $10,000 in exempt sales for resale.

• Net Taxable Base: $90,000
• State Rate: 5.6% ($5,040)
• County Rate (Maricopa): 0.7% ($630)
• City Rate (Phoenix): 2.3% ($2,070)
• Total TPT Liability: $7,740

Example 2: Copper Mining Operation

A mining company extracts copper with a net severance value of $500,000. They are also subject to certain TPT provisions, but we will focus on Severance.

• Severance Value: $500,000
• Severance Rate: 2.5%
• Severance Tax Due: $12,500

Key Factors That Affect Tax Results

Several variables can significantly alter your Arizona tax liability:

• Business Classification: Different business codes (e.g., contracting vs. retail) have different rates and allowable deductions.
• Jurisdiction Boundaries: Moving your business across the street could change your City or County rate. Always verify your jurisdiction.
• Tax Factoring: Vendors may choose to “factor” tax into the price rather than adding it on top. This changes how Gross Receipts are reported.
• Exemptions: Sales to government entities, nonprofits, or for resale are often exempt, lowering your Net Taxable Base.
• Accounting Basis: Reporting on a Cash vs. Accrual basis affects when the tax is due.
• Thresholds: Some cities have tiered rates for large single-item purchases (e.g., a car or machinery).
