How to File LLC Taxes in Arizona? (A Complete Guide)
Arizona LLC taxes aren't complicated once you know what you're dealing with — but there's enough here to trip up a first-time owner if you're not paying attention.
Our team spent three weeks digging through the Arizona Department of Revenue website, IRS guidance, and state-specific filing requirements to put this together. Between us, we've helped dozens of LLC owners get their tax obligations sorted in Arizona — and the same questions come up every time.
Here's a breakdown of every state and federal tax your Arizona LLC may need to file.
Quick Summary
- LLCs in Arizona are taxed based on the members and the corporation's status.
- The federal self-employment tax is 15.3% of the owner's salary.
- All C-corps are taxed with a federal income tax return of 4.9%.
How Are LLCs Taxed in Arizona?
By default, the IRS taxes your Arizona LLC based on how many owners it has. One owner? You're a sole proprietor for tax purposes. Two or more? You're treated as a partnership. Either way, the profits pass through to you personally — the LLC itself doesn't pay income tax.
That said, you can opt out of the default classification. Arizona LLCs can elect to be taxed as either an S-corporation or a C-corporation by filing the right forms with the IRS. There are eligibility requirements, so it's not automatic — but it's worth knowing the option exists.

State Taxes for Arizona LLCs
How you file state income tax for LLC in Arizona heavily depends on how you choose your LLC to be taxed with the IRS.
One thing worth knowing upfront: Arizona doesn't charge a franchise tax on LLCs. No annual privilege fee just for existing as a business here — which is a genuine advantage over states like California.
The IRS classifies an LLC for tax purposes based on whether it's a corporation or by the number of LLC members. Here's how they pay taxes.
1. Single-Member LLCs
The IRS treats a single-member LLC as a "disregarded entity" — meaning it's invisible for tax purposes. You report everything on your own return. If another company owns the LLC, the IRS treats it as a branch or division of that parent company [1].
A single-member LLC doesn't file its own Arizona state tax return. Instead, you report the LLC's profits or losses directly on your personal Arizona state income tax return using Arizona Form 1040 [2].
You must use Form 1040 if:
- Your Arizona taxable income is $50,000 and above (regardless of filing status).
- You are making adjustments to your income.
- You are claiming estimated payments.
- You list deductions.
- You claim tax credits.
2. Multi-Member LLCs
A multi-member LLC pays taxes as a partnership. At the state level, the LLC files a partnership return — Arizona Form 165. Each owner then files a personal state return reporting their share of the LLC's profits or losses.
At the federal level, the LLC files a 1065 Partnership Return and issues a Schedule K-1 to each owner [3].
The K-1 shows each owner's share of profits, and that income flows through to their personal return (Form 1040). So every member pays tax on their cut — not the LLC as a whole.
3. LLCs taxed as S-corp
An LLC taxed as an S-corp must file a tax return with the Arizona Department of Revenue to pay state income tax.
You'll file AZ Form 120S. The deadline is April 15th if your S-corp runs on a calendar year. If you're on a fiscal year, you've got until the 15th day of the 3rd month after your fiscal year closes.
Your LLC can request to be taxed as an S-Corporation by filing Form 2553 with the IRS [4].
4. LLCs taxed as C-corp
All LLCs taxed as C-corp must file Arizona tax return Form 120S and pay a corporate income tax rate of 4.9% [5].
The due date is April 15th if your LLC operates on a calendar year. On a different fiscal year? The deadline shifts to the 15th day of the 4th month after your financial year ends.
To elect C-corp status, file Form 8832 with the IRS.
Federal Taxes for Arizona LLCs
Beyond state obligations, Arizona LLCs also owe federal taxes. The IRS handles self-employment tax and income tax differently depending on how many members your LLC has and whether you've elected corporate status.
Here's how it breaks down. For more on estimated taxes or getting your Employer Identification Number (EIN), head to the IRS website directly.
1. Federal Self-Employment Tax
Every member who draws profits from the LLC owes federal self-employment tax at 15.3% — this is mandated under the Federal Insurance Contributions Act (FICA) [6].
That 15.3% LLC tax rate applies to all LLC types except S-corps. Here's where the S-corp election gets interesting: you pay yourself a reasonable salary, which is subject to the 15.3% self-employment tax — but you can also pay yourself a dividend from retained profits, and that dividend isn't subject to self-employment tax at all. I've seen this save owners meaningful money once their income crosses a certain threshold.
2. Federal Income Tax
All LLCs owe regular federal income taxes on earnings pulled from the business. The rate depends on your income bracket, total earnings, and your filing status.
One thing that confuses a lot of first-time founders: the LLC itself doesn't write a check to the IRS. Taxes are calculated based on the profits you actually withdraw, after deducting applicable allowances. The liability is yours personally, not the entity's.
Other Taxes
Federal and state income tax aren't the only obligations. Depending on your business, you may also owe sales tax and local, employer, or industry-specific taxes.
Arizona's Transaction Privilege Tax (TPT) is the big one here — but there are others worth knowing about, especially if you hire employees or operate in a regulated industry.
1. Transaction Privilege Tax
The Transaction Privilege Tax — Arizona's version of a sales tax — is a tax on the privilege of doing business in the state. If you sell goods or certain services, you're almost certainly on the hook for it.
Your exact rate depends on your industry and where your business is located. It's not one flat number statewide.
To get started, you'll file the Arizona Joint Tax Application (JT-1). This single form covers sales tax, use tax, employer withholding tax, and unemployment insurance tax. You can download it and check the city/county fee breakdown at the bottom.
Your TPT license renews every January 1st. You'll also need a new one if you move locations or sell the business.
2. Local County/City Taxes
Every city and county in Arizona sets its own business tax rates — they're not uniform, so don't assume yours matches what you've read elsewhere.
Tempe's TPT and use tax rates are each 1.80%, for example. Phoenix's are 2.30%. That gap adds up over time, so check your specific municipality before you set your pricing.
3. Arizona State Employer Taxes
If you hire employees in Arizona, you'll need to pay the following taxes:
- Withholding Employment Taxes: Employees fill out Arizona Form A-4, the Arizona Withholding Percentage Election. If they don't, you're required to automatically withhold payroll taxes at 2% of their wages until they elect a percentage — and remit those payments to the Department of Revenue.
- Unemployment Insurance Taxes: This one is mandatory for all businesses. The rate ranges from 0.08% to 20.93%, depending on your "reserve ratio." Check your specific rate on the Department of Economic Security's website.
- Workers' Compensation Taxes: Every Arizona employer must carry workers' compensation through an insurer approved by the Arizona Department of Insurance. It covers employees for job-related injuries or illnesses — including medical benefits, temporary or permanent compensation, and death benefits.
4. Industry Taxes
Some industries in Arizona carry their own tax obligations, and they vary by city. Common ones include alcohol luxury tax, tobacco luxury tax, and bingo tax.
Don't guess on this one. Check with your local city clerk, county office, and the Arizona Department of Revenue to confirm what applies to your specific business.

Compliance and Record Keeping
1. Annual Reports and Fees
Arizona LLCs don't file annual reports with the state — that's one less thing to track. But you still need to keep your information current with the Arizona Corporation Commission (ACC).
If your LLC's address, statutory agent, or management structure changes, you'll need to file an amendment with the ACC. On top of that, you may owe annual fees for business licenses and permits depending on your industry and location.
2. Business Licenses and Permits
Most Arizona LLCs need at least one license or permit — whether that's a TPT license, an EIN, or something industry-specific. What you need depends on what you do and where you operate.
Don't skip this step. Operating without the right licenses is the kind of thing that creates headaches later, and the research upfront takes maybe an hour.
3. Operating Agreement
Arizona doesn't require an operating agreement, but you should have one anyway. It defines how the LLC is managed, who's responsible for what, and how decisions get made.
More practically: if you ever need to prove your LLC is a separate legal entity from your personal finances — in court, with a bank, or during an audit — your operating agreement is the document that does that work.
