The short answer
It depends. Arizona has trade-offs: Newspaper publication required (Maricopa/Pima exempt). For most founders, alternatives like Wyoming or your home state are simpler.
Three deciding questions
1. Do you live or operate in Arizona?
If yes, form here. Out-of-state formation while operating in Arizona costs double, not half.
2. What is the 5-year all-in cost?
$300 (filing + 5 × annual report + $50 registered agent + franchise minimums). This is the actual number to compare across states.
3. What are your three real requirements?
- Privacy: 5/10 (moderate — members appear on public filings).
- Banking: 7/10 (workable but not premium).
- Cost: low 5-year total.
Arizona pros
- No annual report fee
- Low filing fee
- Flat low income tax
Arizona cons
- Newspaper publication required (Maricopa/Pima exempt)
Most common alternative
Wyoming for cost + privacy. Delaware for VC-backed startups. Your home state if you operate there. Run the 5-question quiz for a personalized shortlist.
