There's no such thing as a separate "LLC tax" in Arizona. An LLC itself doesn't pay federal or state income tax by default; the profit passes through to the owner's personal return, where it's taxed as self-employment income. What you actually owe depends entirely on how the LLC is classified: disregarded, partnership, S-corp, or C-corp. Here's the full 2026 breakdown by classification, plus what Arizona charges regardless of how you're taxed.

Key Takeaways

• Arizona LLCs pay no entity-level income tax, franchise tax, or annual LLC fee by default. The state doesn't tax the LLC itself; it taxes the owner's share of the profit.
• A single-member LLC's profit is subject to 15.3% self-employment tax (Social Security and Medicare), plus federal income tax, plus Arizona's flat 2.5% individual income tax.
• Multi-member LLCs file an informational partnership return (Form 1065) and issue K-1s; each member reports and pays tax on their share individually.
• Electing S-corp taxation can reduce self-employment tax exposure once profit is consistently high enough, commonly cited as roughly $40,000–$60,000+ in net profit, but it adds payroll costs and complexity.
• Arizona's Transaction Privilege Tax (TPT) is separate from income tax entirely. It applies only if the LLC sells taxable goods or services, not to the LLC's profit itself.
• Formation costs $50 (or $85 expedited) through the Arizona Corporation Commission, and there's no annual report or renewal fee for LLCs, unlike corporations.

Arizona LLCs Aren't Taxed as a Separate Entity by Default

By default, the Arizona Department of Revenue treats a single-member LLC as a disregarded entity: a branch or division of its owner for tax purposes, not a separate taxpayer. A multi-member LLC defaults to partnership taxation. In both cases, the LLC itself files no income tax return and pays no income tax. The profit flows through to the owner's (or owners') personal return, where it's taxed once.

The entity type (LLC) and the tax classification (disregarded, partnership, S-corp, or C-corp) are two different things, and mixing them up is where most of the confusion around LLC taxes starts. An LLC can be taxed any of these four ways depending on elections you make.

How a Single-Member LLC Is Taxed

A single-member LLC's net profit is reported on Schedule C of the owner's Form 1040 and taxed three ways:

1. Self-employment tax: 15.3% on 92.35% of net profit, covering Social Security (12.4%, up to the 2026 wage base of $184,500) and Medicare (2.9%, uncapped). Half of this is deductible above the line.
2. Federal income tax on the remaining taxable income, after the standard or itemized deduction and the Qualified Business Income (QBI) deduction, which can shelter up to 20% of qualified business income.
3. Arizona income tax at the flat 2.5% rate.

Here's how that plays out for a single filer with $150,000 in net LLC profit and no other income, using 2026 figures:

That's an illustrative example only, not a quote, since actual figures shift with filing status, deductions, retirement contributions, and other income. But it shows the shape of it: self-employment tax is often the single largest line item for a profitable default-taxed LLC, bigger than the federal and state income tax combined.

How a Multi-Member LLC Is Taxed

A multi-member LLC defaults to partnership taxation. The LLC files Form 1065, an informational return, and issues each member a Schedule K-1 showing their share of income, deductions, and credits. Each member then reports their K-1 income on their own return and pays self-employment tax on their share (active members generally owe SE tax on their distributive share; guaranteed payments for services are also subject to it). Arizona applies its flat 2.5% rate to each member's Arizona-source share individually; the partnership itself doesn't pay Arizona income tax.

Electing S-Corp Status: When It Lowers Your Tax Bill

An LLC (single- or multi-member) can elect to be taxed as an S-corporation by filing IRS Form 2553. The entity stays the same; only the tax treatment changes. Under an S-corp election, the owner becomes an employee of their own business, paid a reasonable W-2 salary subject to regular payroll taxes (the same 15.3% FICA, split between employer and employee halves), while remaining profit is distributed to the owner and is not subject to self-employment tax at all.

That's the entire mechanism behind the S-corp tax savings pitch: shrinking the base subject to SE/FICA tax down to just the salary portion, instead of the full net profit. The tradeoffs are real, though. You take on payroll processing (typically $500–$1,500+ per year), a somewhat more complex tax return, and the requirement to pay yourself a defensible "reasonable compensation" rather than an artificially low one. Common professional guidance places the point where the payroll tax savings start outweighing the added cost somewhere around $40,000 to $60,000+ in consistent annual net profit. Treat that as a range worth checking against your numbers, not a guarantee.

One more wrinkle worth knowing: S-corp wages reduce the QBI deduction base, since W-2 wages paid to the owner don't count as qualified business income. Above the 2026 QBI thresholds ($201,775 single / $403,500 married filing jointly), the wage limitation can matter more, so an S-corp election isn't automatically the right move for every profitable LLC. It's worth modeling both ways before filing the election.

Electing C-Corp Status

An LLC can also elect C-corporation taxation via Form 8832. This is far less common for small operators because it introduces double taxation: the corporation pays Arizona's 4.9% corporate income tax (with a $50 minimum, and ranking among the more competitive corporate rates nationally) plus federal corporate tax on its profit, and then any dividends paid out to the owner are taxed again at the individual level. C-corp treatment tends to make sense in specific situations, like retaining significant earnings inside the business or planning for outside investment, rather than as a default choice for a profitable owner-operated LLC.

Arizona's Transaction Privilege Tax (TPT): A Separate Question Entirely

None of the above touches Arizona's Transaction Privilege Tax. TPT is a tax on the business for the privilege of selling certain goods or engaging in certain taxable activities, currently 5.6% at the state level plus local add-ons. It applies based on what your LLC sells, not on its profit or its tax classification. A consulting LLC providing professional services generally owes no TPT at all; a retail LLC selling physical products almost certainly does. If your LLC engages in a taxable activity, you'll need a TPT license through the Arizona Corporation Commission formation process and ongoing filing through AZTaxes.gov, entirely separate from your income tax obligations.

Formation and Ongoing Compliance Costs

Arizona is inexpensive to form and maintain an LLC in, relative to many states:

• Articles of Organization: $50 standard, $85 expedited, filed with the Arizona Corporation Commission.
• Statutory agent required. You can serve as your own if you have an Arizona street address, or hire a commercial statutory agent service.
• Publication requirement. Newspaper publication is required within 60 days of approval, unless your statutory agent's address is in Maricopa or Pima County, in which case the ACC posts the notice online instead.
• No annual report and no annual fee for LLCs. This is a meaningful difference from Arizona corporations, which file an annual report ($45 fee), and from many other states that charge LLCs a recurring franchise tax or annual fee just to stay registered.

Why This Matters More for Real Estate Investors and High Earners

• Real estate investors holding property in an LLC should understand that rental income generally isn't subject to self-employment tax, since most rental activity doesn't rise to the level of a trade or business for SE tax purposes, unlike active business income. This is a meaningfully different calculation than the Schedule C example above; see our guide on the tax consequences of selling a rental property for what happens on the disposition side.
• High earners approaching the S-corp break-even point should model it properly rather than guess. Our piece on why high earners often overpay their taxes covers the S-corp election as one of several strategies most default-taxed LLC owners never get around to evaluating.
• Timing the election matters. An S-corp election has to be made within specific IRS deadlines relative to your tax year; waiting until you're preparing the return is usually too late to apply it retroactively. See tax planning versus tax preparation for high-income earners for why that timing gap costs real money.
• Business owners donating to Arizona causes can stack credits on top of whichever classification they choose, since these are individual credits claimed on the owner's personal return regardless of the LLC's tax treatment; see Arizona Tax Credits for the full list.

The Bottom Line on Arizona LLC Taxes

An Arizona LLC's tax bill isn't set by the entity type. It's set by the tax classification you choose and the profit that flows through it. Default taxation means the full 15.3% self-employment tax on net profit, plus federal tax, plus Arizona's flat 2.5%. An S-corp election can reduce that self-employment tax exposure once profit is consistently high enough to justify the added payroll complexity. Arizona's TPT sits entirely outside this calculation and depends on what you sell, not how you're taxed.

Frequently Asked Questions

Does an LLC pay taxes in Arizona? The LLC itself typically doesn't, if it's taxed as a disregarded entity or partnership. The owner or members pay tax on the LLC's profit on their personal returns, including federal self-employment tax and Arizona's flat 2.5% income tax.

How is a single-member LLC taxed in Arizona? As a disregarded entity by default. Profit is reported on Schedule C of the owner's Form 1040, subject to 15.3% self-employment tax, federal income tax, and Arizona's flat 2.5% rate.

Should I elect S-corp status for my Arizona LLC? It depends on your consistent net profit. Common guidance places the tipping point around $40,000–$60,000+ in annual profit, where payroll tax savings start to outweigh the added payroll and compliance costs, but this varies by situation and should be modeled with real numbers.

Does Arizona have an LLC franchise tax? No. Arizona has no franchise tax and no annual fee for LLCs, unlike many other states.

Do I need to file an annual report for my Arizona LLC? No. Arizona LLCs don't file annual reports. Corporations do ($45 fee), but LLCs are exempt from that requirement entirely.

Does my LLC need to collect Arizona sales tax (TPT)? Only if it engages in a taxable business activity, generally selling tangible goods or certain services. TPT is unrelated to your LLC's income tax classification and depends entirely on what the business sells.
