How much does it cost to start a business in Arizona?
Doing it yourself, expect about $80 in year one — that's the Arizona LLC filing fee and the unavoidable state charges. With a registered agent service and a paid operating agreement it's closer to $380. Here's every line item, and what you can skip. Arizona requires newspaper publication of your LLC formation in most counties (Maricopa and Pima are exempt).
Arizona LLC filing fee — $50
The one required government charge to create the LLC — filing the Articles of Organization with Arizona. Processing is 14–16 business days (regular). File directly with the state; a "filing service" just adds a markup on top of this.
Registered agent — $0–$150/yr
$0 if you're your own agent (you need a physical Arizona street address and to be around during business hours). A service runs about $100–$150/year and keeps your home address off the public record.
EIN (federal tax ID) — $0
Free from the IRS in about 10 minutes online. Anyone charging you for an EIN is reselling a free government service.
Operating agreement — $0–$100
Free with a solid template (you keep it, you don't file it). A lawyer or a formation upsell charges $100+ for the same single-member document.
Newspaper publication (one-time) — ~$30 once
Required within 60 days of formation in every county except Maricopa and Pima. Typically $30–$300 depending on the paper.
Ongoing Arizona report — $0
Arizona doesn't require an ongoing LLC report — just keep your agent and address current.
Local business license — $0–$150
Many cities and counties require a general business or occupational license (often $50–$150/year); some have none. This is separate from the state and depends on where you operate.
Business bank account — $0–$15/mo
Plenty of banks and credit unions offer free small-business checking. Keep business and personal money fully separate — it's what makes the LLC's liability shield hold up.

Build my planFrequently asked
What's the cheapest way to start a business in Arizona?
Register as a sole proprietor (no state filing, $0) and get a free EIN. The trade-off is no liability protection — your personal assets are exposed. The cheapest way to get that protection is a DIY LLC: about $80 in year one, filing directly with the state and acting as your own registered agent.
How much is an LLC in Arizona?
The state charges $50 to file. After that, budget roughly $125/year ongoing — the Arizona report plus a registered agent if you keep one. An EIN and operating agreement can both be $0.
Do I have to pay LegalZoom or a filing service?
No. Every required step — the state filing, the EIN, the operating agreement — you can do yourself for the government fee alone. Filing services bundle a markup onto the same $$50 state fee. FirstBearing gives you the filled-in forms and the official links so you file direct.
What ongoing costs should I expect in Arizona?
About $125/year: Arizona's report fee, a registered agent renewal if you use a service (~$125), and any local business license. That's before taxes on what you actually earn.
Is there a fee to get an EIN in Arizona?
No. The EIN comes from the IRS, not the state, and it's free. Apply directly at IRS.gov — never pay a third-party site for one.
