Arizona Sole Proprietorship vs LLC:
$50 Filing, No Annual Report (2026)
Arizona has one of the cheapest ongoing LLC structures in the country: a $50 filing fee and no annual report. The complication unique to Arizona is the publication requirement, a holdover from older corporate formation laws.

Filing is through the Arizona Corporation Commission (azcc.gov). Online filings are processed within several business days; expedited service costs an additional $35-$200 depending on speed. The Articles of Organization form is L010, a single-page document requiring the LLC name, statutory agent, member or manager information, and organisational structure (member-managed or manager-managed).
The Publication Requirement
Within 60 days of filing the Articles of Organization, an Arizona LLC must publish a notice of formation in a newspaper of general circulation in the county of the statutory agent's address. The notice must run for three consecutive weeks. After publication completes, the newspaper sends an affidavit of publication that must be filed with the Arizona Corporation Commission.
Maricopa County (Phoenix metro) and Pima County (Tucson metro) are exempt from the publication requirement. LLCs with statutory agent addresses in those two counties skip publication entirely. For statutory agent addresses in any of Arizona's other 13 counties (Yavapai, Coconino, Mohave, Navajo, etc), the publication is mandatory and the cost varies by newspaper rate card. Yavapai County newspapers typically charge $50-$150 for the three-week publication; rural-county weekly newspapers can be lower.
The practical workaround: use a commercial statutory agent service (Northwest Registered Agent, InCorp, ZenBusiness, and similar services typically charge $100-$300/year for statutory agent in Arizona) that is located in Maricopa or Pima county. That moves the publication-trigger address into an exempt county and saves the $50-$300 publication cost plus the administrative time of arranging publication. Many out-of-county Arizona LLCs use this pattern as a matter of routine.
Transaction Privilege Tax (TPT)
Arizona's sales tax equivalent is the Transaction Privilege Tax, administered by the Arizona Department of Revenue. TPT applies broadly to retail sales, restaurant sales, lodging, and certain services, with rates varying by business activity classification. The state TPT rate is 5.6% for most retail sales, and city and county adders bring combined rates to 8%-10.7% depending on location (Phoenix proper is 8.6%, Tucson is 8.7%, Sedona is 10.4%).
Sole proprietors selling taxable goods or services in Arizona must register for a TPT licence regardless of LLC status. The state TPT licence is $12 per location, renewed annually. City licences range from $0 to $50 per city depending on city ordinances. Online sellers with no Arizona physical presence may still owe TPT under economic nexus thresholds (Arizona adopted the $100,000 South Dakota v Wayfair-style threshold for remote sellers).
For sole prop or LLC service providers (consulting, freelancing, professional services not in a TPT-taxable category), TPT registration is not required. The Arizona Department of Revenue website has a TPT taxability matrix; check the specific business activity classification (e.g. "Retail Sales", "Restaurant", "Personal Care Services") for applicability. The entity choice does not change TPT obligations.
State Income Tax: Flat 2.5%
Arizona moved to a flat 2.5% personal income tax rate effective January 2023, one of the lower rates in the country. This rate applies to both sole proprietor net profit (passed through on the Form 1040 / Arizona Form 140) and LLC member income (single-member LLC disregarded entity passes through identically; multi-member LLC files Arizona Partnership Return and members report on individual returns). The flat rate eliminated the previous progressive bracket structure.
For an Arizona sole proprietor or LLC member, the state income tax on $100,000 of business net profit is $2,500. For a higher earner, the same flat 2.5% applies regardless of bracket. The structural simplicity of the Arizona flat rate makes Arizona one of the friendlier states for higher-income sole proprietors and LLC members, particularly compared to California's 13.3% top rate or New York's 10.9% top rate. Combined with the cheap LLC formation costs and absent annual report, Arizona ranks as one of the better-cost states for both entity types.
Home-Based Business Considerations
Many Arizona sole props and small LLCs operate from a residential address. Most Arizona cities permit home-based businesses subject to zoning ordinances that restrict employee count, customer foot traffic, signage, and outdoor storage. Phoenix's home occupation permit (free for most home-based businesses meeting the criteria) is a typical example: the business must be incidental to the primary residential use, no more than one non-resident employee, no exterior storage or signage, and limited customer visits.
Maricopa County, Pima County, and other urban counties may have additional county-level requirements for some business types. HOA covenants often restrict commercial activity in residential properties beyond what local zoning permits; check the HOA covenants before operating a customer-facing home business in any HOA-governed property. Tucson, Mesa, Chandler, Scottsdale, and Tempe all have similar home-occupation permitting structures.
None of these home-based business considerations change between sole prop and LLC structure. The zoning rules apply to the activity at the address, not to the legal entity conducting it. Entity choice is a separate question handled at state level via the Arizona Corporation Commission.
Recommendation for Arizona Residents
Stay sole prop if...
- Net profit under $30K, low-risk freelance or service work
- No employees, no plans to hire
- Sole revenue source is within Arizona, no multi-state nexus
- No client contract specifically requires entity status
Form an Arizona LLC if...
- Net profit clears $50K (consider S-Corp election too)
- Higher-liability work (physical services, retail, food)
- Need entity for client contracts or government work
- Owning rental property (one LLC per property pattern)
