You will need to choose a business structure, register with the state, obtain local permits, and set up your tax accounts. The entire process can take as little as one day if you use expedited filing, or two to three weeks at standard speed.

- Tourism and hospitality (over 45 million annual visitors)
- Real estate and construction (driven by rapid population growth)

Pro Tip
Write a Business Plan
Draft a business plan that covers your target market, revenue model, startup costs, and 12-month financial projections. Banks and SBA lenders require a formal business plan before approving any financing.
Follow our step-by-step business plan guide to build a plan that works for both lender applications and your own strategic planning. Keep the document under 20 pages and focus on realistic numbers backed by local market data.
Pro Tip
Choose Your Business Structure in Arizona
Most founders in Arizona choose an LLC because it combines personal liability protection with pass-through taxation and minimal paperwork. Filing an LLC costs $50 at the Arizona Corporation Commission.
Your four main options are sole proprietorship, LLC, S-Corp, and C-Corp. Read our Arizona LLC formation guide for a detailed walkthrough. See the full comparison below before deciding.
Pro Tip
Business Structure Comparison — Arizona
Full comparison guide| Structure | Arizona Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | Free / No State Filing | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $50 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$50 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $60 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in Arizona pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full Arizona LLC guide →
Choose and Register Your Business Name
Your business name must be distinguishable from every other entity on file with the Arizona Corporation Commission. Search the Arizona business name database to check availability before filing.
LLCs must include "LLC" or "Limited Liability Company" in the official name. You can reserve your name for 120 days by filing a Name Reservation for $10 (or $45 expedited).
Pro Tip
Check Arizona Business Name Availability
Search the official Arizona Corporation Commission database before you file.
Register Your Business with the State
File your Articles of Organization with the Arizona Corporation Commission online for $50. Standard processing takes 13 to 16 business days, but you can pay $35 for expedited processing or $200 for same-day service.
You will need a registered agent with a physical Arizona address. See our Arizona registered agent guide for affordable options.
After approval, Arizona requires most LLCs to publish a notice of formation in an approved local newspaper for three consecutive weeks. Publication costs range from $60 to $300 depending on your county.
Pro Tip
Important
File Online with Arizona Corporation Commission
Official Arizona business registration portal. Standard processing: 13-16 business days.
Get Your Federal EIN from the IRS
Apply for a free Employer Identification Number (EIN) directly from the IRS online portal. The process takes about 10 minutes, and you receive your EIN immediately.
You need an EIN to open a business bank account, hire employees, and file federal taxes. Never pay a third-party service for an EIN since the IRS provides them at no cost.
Pro Tip
Get Your Arizona Licenses and Permits
Requirements vary by industry and location, but most Arizona businesses need:
- Transaction Privilege Tax (TPT) License (required if selling taxable goods or services; register free at the Arizona Department of Revenue)
- City or Town Business License (required in most municipalities; fees range from $7 to $100+)
- Professional License (required for contractors, healthcare providers, real estate agents, and other regulated fields through the relevant Arizona licensing board)
- Employer Registration (required before hiring; register with the Arizona Department of Economic Security)
Check with your city or town clerk's office for the specific permits required at your business location.
Pro Tip
Open a Business Bank Account
Bring your EIN confirmation letter, Articles of Organization, operating agreement, and a government-issued ID to open a dedicated business checking account. Separating personal and business finances is essential for maintaining your LLC's liability protection.
Compare options in our best business bank accounts guide to find accounts with no monthly fees and strong online banking features. Many Arizona credit unions offer free business checking for small companies.
Pro Tip
Set Up Accounting and Understand Arizona Taxes
Arizona imposes a 2.5% flat individual income tax rate, which applies to LLC pass-through income. The state also charges a Transaction Privilege Tax (TPT) starting at 5.6%, with local additions pushing the combined rate up to 11.2% in some cities.
Register for TPT through the Arizona Department of Revenue before making your first taxable sale. You will need to file and remit TPT on a monthly, quarterly, or annual basis depending on your revenue.
Set up accounting software early to track income, expenses, and tax obligations. Our best accounting software guide compares top options for new businesses.
Pro Tip
Get Business Insurance in Arizona
Arizona requires businesses with at least one employee to carry workers' compensation insurance. Even sole-member LLCs should consider general liability coverage to protect against lawsuits and property damage claims.
Compare policy options in our best business insurance guide. Most Arizona small businesses can secure a general liability policy starting around $30 to $50 per month.
Pro Tip
Important
Build Your Online Presence
Claim your free Google Business Profile immediately after registering your business. This puts your company on Google Maps and local search results, which is especially important for Arizona service-area businesses.
Build a professional website using one of the platforms in our best website builders guide. A simple five-page site with your services, contact info, and reviews is enough to start generating leads.
Stay Compliant After Forming in Arizona
