Is it cheaper to form an LLC in Arizona or Michigan?

Formation fees are identical: $50 in both states. The year-over-year cost is where they differ. Arizona runs $100 per year after formation, Michigan runs $125.

Can I form an LLC in Arizona if I live in Michigan?

Yes, but your Michigan business will almost certainly need to register as a foreign LLC in Michigan too, which means paying Michigan's foreign registration fee and any ongoing Michigan 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 Michigan?

Arizona online: 14 business days; Michigan online: 7 business days. Arizona offers paid expedite from $35. Michigan offers paid expedite from $50.

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

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

Arizona vs Michigan LLC comparison

Arizona charges $50 to form an LLC; Michigan charges $50. 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 $75 less in total state fees than Michigan. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

On speed, Michigan 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.

What it costs under your specific situation

The table below runs the same LLC through four common scenarios. "Non-resident" rows assume a typical home-state foreign LLC registration adds about $200 per year of stacked cost; the real number depends on which state you live in and ranges from $50 to over $800 depending on jurisdiction.

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

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

Michigan

Check business-name availability on the Michigan entity search.
Appoint a registered agent with a physical Michigan street address.
File Articles of Organization, Domestic Limited Liability Company (Form CSCL/CD-700) for $50.
Wait for approval. Online typically 7 business days. Paid expedite from $50.
Adopt an operating agreement (recommended, not required by Michigan statute).
Apply for a federal EIN (free from the IRS).
Open a business bank account to separate personal and business finances.
File your first annual report and pay $25 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 Michigan (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 Michigan 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.

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.
