Arizona charges $50 to form an LLC; Washington charges $180. Day-one sticker price is only part of the story, since most of the real cost comes from the annual obligations that stack up each year you keep the LLC open.

Over a rolling three-year window, Arizona runs about $340 less in total state fees than Washington. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

On speed, Washington typically clears standard online filings faster than Arizona. Both states offer expedited tiers at an additional cost for filers on tight timelines.

For most small operators the choice is not really between these two states at all. It is between forming where the business actually operates and trying to route through a non-resident filing. The data below shows what each option actually costs.

Key differences at a glance

  • Arizona costs $130 less to form ($50 vs $180).
  • Arizona is $70 per year cheaper to maintain ($100 vs $170).
  • Washington has no state individual income tax; pass-through LLC income flows to members without a state layer. The other state does tax at the member level.
  • Arizona requires newly formed LLCs to publish a formation notice in local newspapers; this can add $50 to $1,800 depending on county.
  • Arizona has no annual report filing at all. Washington requires an annual (or biennial) report every reporting period.

Where each state fits

For most filers, forming in the state you actually operate from is the right call. The side-by-side below shows where the two states meaningfully diverge.

Formation process, side by side

What actually happens from the moment you start filing to the moment you're in good standing. Use this as a checklist.

Arizona

  1. Prepare a publication-ready notice (required in Arizona).
  2. Check business-name availability on the Arizona entity search.
  3. Appoint a registered agent with a physical Arizona street address.
  4. File Articles of Organization (Form L010) for $50.
  5. Wait for approval. Online typically 14 business days. Paid expedite from $35.
  6. Adopt an operating agreement (recommended, not required by Arizona statute).
  7. Apply for a federal EIN (free from the IRS).
  8. Open a business bank account to separate personal and business finances.
  9. No annual state filing required in Arizona.

Washington

  1. Check business-name availability on the Washington entity search.
  2. Appoint a registered agent with a physical Washington street address.
  3. File Certificate of Formation - Limited Liability Company for $180.
  4. Wait for approval. Online typically 5 business days. Paid expedite from $100.
  5. Adopt an operating agreement (recommended, not required by Washington statute).
  6. Apply for a federal EIN (free from the IRS).
  7. Open a business bank account to separate personal and business finances.
  8. File your first annual report and pay $70 when it comes due.

Before you pick either state

A few things that apply no matter which state you choose. These trip up enough first-time filers that they're worth stating explicitly.

Registered agent is non-negotiable. Both Arizona and Washington (and every other US state) require every LLC to designate a registered agent with a physical street address in the state of formation. You can serve as your own agent if you live in the state; otherwise a commercial agent runs $50 to $125 per year. Using your own home address makes it part of the public record.

Forming elsewhere does not escape your home state's tax. If you live and operate a business from your home state, forming the LLC in Arizona or Washington does not avoid your home state's income tax. The moment you transact business at home, your home state requires a foreign LLC registration, and state tax liability follows your residence regardless of where the entity sits on paper.

EIN applications are free. The IRS issues Employer Identification Numbers directly at no cost. Any service charging you to "get your EIN" is reselling a free form submission. Single-member LLCs with no employees technically don't need one for federal tax, but nearly every bank requires an EIN to open a business account.

Operating agreement matters more than the state you pick. A well-drafted operating agreement governs member ownership, management, profit splits, buy-sell terms, and dissolution. Without one, your LLC runs on the state's default rules, which are rarely what you want. California, Maine, Missouri, and New York require a written one by statute; every other state treats it as strongly recommended.

Frequently Asked Questions

  • Is it cheaper to form an LLC in Arizona or Washington?

    Arizona is cheaper at formation ($50) than Washington ($180). Ongoing costs are also different: $100 vs $170 per year. Total over three years: $350 vs $690.

  • Can I form an LLC in Arizona if I live in Washington?

    Yes, but your Washington business will almost certainly need to register as a foreign LLC in Washington too, which means paying Washington's foreign registration fee and any ongoing Washington obligations on top of the Arizona ones. The "form elsewhere to save" math usually doesn't work for operating businesses; it only works when you have no physical operations tied to any specific state.

  • How long does it take to form an LLC in Arizona vs Washington?

    Arizona online: 14 business days; Washington online: 5 business days. Arizona offers paid expedite from $35. Washington offers paid expedite from $100.

  • Which state has lower taxes for an LLC, Arizona or Washington?

    Arizona: state income tax applies to member-level pass-through income, no entity-level franchise or LLC tax. Washington: no state income tax, no entity-level franchise or LLC tax.

  • Do both states require a registered agent?

    Yes. Every US state (and DC) requires every LLC to maintain a registered agent with a physical street address in the state. Arizona and Washington both have this requirement. You can serve as your own agent if you live in the state; most out-of-state filers use a commercial agent for $50 to $125 per year.

  • Does Arizona or Washington have a publication requirement?

    Arizona does. New LLCs must publish a formation notice in approved newspapers, which can add $50 to $1,800 to your first-year cost depending on the county where the LLC is based. Washington has no publication requirement.

  • Which state should I pick if I run an online business from home?

    Form in the state you actually live in. Your home state's Department of Revenue treats your residence as nexus regardless of where the LLC is filed, which means you owe state income tax there anyway. Forming in Arizona or Washington to escape your home state's tax doesn't work; it adds paperwork. The non-resident filings make sense when you genuinely operate nowhere in particular: international founders, purely passive holding entities, or real-estate LLCs owning property in other states.

  • Operating agreement requirement: www.azleg.gov/ars/29/03105.htm · verified April 21, 2026
    A.R.S. §29-3105 (Arizona Limited Liability Company Act) recognizes an operating agreement as the governing document among members and permits it to be oral, written, implied, or any combination. There is no statutory requirement that an LLC adopt an operating agreement, so this is recorded as not required.
  • Publication requirement: www.azleg.gov/ars/29/03201.htm · verified April 21, 2026
    A.R.S. §29-3201(G) requires newspaper publication of the notice of LLC formation in the county of the statutory agent's street address for three consecutive publications within 60 days after filing the Articles of Organization, unless the statutory agent's street address is in a county with a population of more than 800,000, in which case the Commission inputs the notice into its public notice database. Only Maricopa County and Pima County exceed that population threshold, so LLCs with statutory agents in those two counties are exempt (covering roughly 75% of Arizona's population). LLCs in the remaining 13 counties must arrange publication; typical newspaper cost is $60-$120.
  • Franchise tax: azdor.gov/forms/corporate-income-tax-highlights · verified April 21, 2026
    Arizona has no franchise tax on LLCs or corporations. The Arizona Department of Revenue levies only a corporate income tax (4.9% on C-corp taxable income, $50 minimum) and the Transaction Privilege Tax (a gross-receipts-style sales tax at 5.6% statewide plus local rates), neither of which functions as a traditional franchise tax.
  • Corporate income tax rate: azdor.gov/forms/corporate-income-tax-highlights · verified April 21, 2026
    Arizona corporate income tax is a flat 4.9% of Arizona taxable income (A.R.S. §43-1111) with a $50 minimum tax. LLCs are pass-through by default and do not owe corporate income tax unless they elect to be taxed as a C-corp. Recorded here for the maxCorporateRate informational field.
  • Sales tax rate: azdor.gov/business/transaction-privilege-tax · verified April 21, 2026
    Arizona's statewide Transaction Privilege Tax (TPT) rate is 5.6%. TPT is technically a tax on the vendor's privilege of doing business rather than a consumer sales tax, but it functions as the state's sales tax. Counties and municipalities add their own TPT rates, with combined effective rates commonly ranging 7.5% to 11.2% across Arizona. Only the 5.6% statewide rate is recorded in salesTaxRate.
  • Business name search: arizonabusinesscenter.azcc.gov/businesssearch · verified April 21, 2026

    RCW 25.15.018 (Washington Limited Liability Company Act) recognizes an LLC agreement that may be oral, written, or implied. There is no statutory requirement that LLCs adopt an operating agreement, so this is recorded as not required. If none is adopted, the default provisions of RCW 25.15 govern.
  • Publication requirement: app.leg.wa.gov/rcw/default.aspx?cite=25.15 · verified April 21, 2026

  • Franchise tax: dor.wa.gov/taxes-rates/business-occupation-tax · verified April 21, 2026
    Washington has no franchise tax on LLCs. Washington's Business & Occupation (B&O) tax is a gross-receipts tax, not a franchise tax. B&O rates in 2026: retailing 0.471%, wholesaling 0.484%, manufacturing 0.484%, service & other activities 1.5% (less than $1M in prior-year taxable income), 1.75% ($1M-$5M), 2.1% (over $5M effective Oct 1, 2025). Additional 0.5% surcharge on WA taxable income over $250M from Jan 1, 2026. Because the B&O is structurally a gross-receipts tax on business activity rather than a capital-based franchise tax, franchiseTax.applies is set to false.
  • Corporate income tax rate: dor.wa.gov/taxes-rates/business-occupation-tax · verified April 21, 2026
    Washington has no corporate income tax; maxCorporateRate is recorded as null. The state's business tax is the B&O gross-receipts tax (captured in franchiseTax.notes). Washington also has no state personal income tax, only a 7% long-term capital gains excise tax for individuals above the threshold.
  • Sales tax rate: dor.wa.gov/taxes-rates/sales-use-tax-rates · verified April 21, 2026
