How to Start a Bookkeeping Business in Arizona
Monthly bookkeeping, reconciliations, and financial reporting for small businesses. Here's the Arizona-specific path — structure, licensing for bookkeeping work, taxes, insurance, and landing your first customers.
Licensing for bookkeeping work in Arizona
No license to do bookkeeping. You may not call yourself a CPA or perform audits/attestation without a CPA license, and preparing tax returns for a fee requires an IRS PTIN. In Arizona, check both your city/county and the relevant state board before you advertise.
What a bookkeeping business needs to open
Monthly bookkeeping, reconciliations, and financial reporting for small businesses. The setup areas that usually matter: Business registration + E&O insurance, Software certifications (QuickBooks, Xero), Engagement letters and workpapers, Monthly retainer pricing, Secure document handling. Typical cost to get operational: $500–$3,000.
Pick a structure (sole proprietor or LLC)
Most Arizona owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $50, and formation typically takes about 14–16 business days (regular). Confirm the current fee on the state site before you pay.
Name a registered agent
If you form an LLC or corporation, Arizona needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
Register for Arizona taxes
Arizona has a state sales/use tax and has a state income tax. Arizona requires newspaper publication of your LLC formation in most counties (Maricopa and Pima are exempt).
Confirm local licenses and permits
Arizona rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.
Open a business bank account and get insurance
Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.
Put the ongoing report on your calendar
Arizona does not require an ongoing entity report for LLCs — one less deadline to track.
Getting your first bookkeeping customers in Arizona
Referrals from CPAs (who don't want the monthly work), local business groups, and a niche-focused site. Monthly retainers make this a highly predictable business. Niching by industry (restaurants, contractors, agencies) lets you templatize and raise rates.
