Wyoming vs Washington LLC: Side-by-Side Comparison (2026)

If you are a non-US founder choosing between a Wyoming LLC and a Washington LLC, the honest answer for the overwhelming majority of people is Wyoming — and the reason is not hype, it is arithmetic. Washington has no personal income tax, which sounds friendly, but it replaces that with a gross-receipts tax (the Business & Occupation, or B&O, tax) that bills you on revenue before a single expense is deducted, plus a public ownership disclosure on every annual report, plus higher state fees. Wyoming charges a flat annual report fee, has no entity-level income or gross-receipts tax, and keeps your name off the public record. Below is a full, source-cited breakdown — including a five-year cost projection across four revenue levels — so you can see exactly where each state wins and where the Washington structure quietly costs you money.

Why Wyoming wins for non-residents

Wyoming is the default home for non-US founders for four concrete reasons, and each one maps to a real line item or a real risk.

First, cost predictability. A Wyoming LLC has no state income tax, no gross-receipts tax, and no franchise tax. Your only recurring state obligation is the annual report, which carries a $60 minimum license tax for LLCs holding under $300,000 of assets in Wyoming — and a non-resident with no Wyoming property pays exactly that floor (Wyoming Secretary of State, "Annual Report" filing requirements). That number does not move whether you bill $0 or $250,000. With WyomingLLC.xyz the year-one package is $397 all-inclusive, with the Wyoming state filing fee already included — no surprise add-on at checkout.

Second, privacy. Wyoming does not require members or managers to be named in the public formation record, and the annual report does not publish your ownership. Washington does the opposite: while the Certificate of Formation itself does not demand member names, the Initial Report and every Annual Report require the LLC's "governors" — Washington's term for members or managers — to be listed publicly (Washington Secretary of State, "Governors/Officers/Directors/Members/Managers" FAQ). For a founder who does not want their name searchable, that is a meaningful structural difference.

Third, asset protection. Wyoming's charging-order protection is the statutory gold standard and explicitly extends to single-member LLCs, with the charging order as the sole remedy a creditor can pursue. Washington's LLC act offers competent but more ordinary protection without Wyoming's single-member clarity.

Fourth, no tax on revenue you have not netted. This is the big one for low-margin businesses. Washington's B&O tax applies to gross receipts attributable to Washington with no deduction for cost of goods, payroll, or overhead (Washington Department of Revenue, "Business & occupation tax"). Wyoming imposes nothing comparable. A non-resident e-commerce or agency owner running on thin margins can owe Washington tax in a year they lost money — an outcome that is impossible in Wyoming.

There is also a quieter fifth advantage worth naming: administrative simplicity. A Wyoming non-resident LLC with no US nexus deals with two recurring obligations — one state annual report and one federal Form 5472 package. A Washington structure layers on a Department of Revenue account, periodic or annual excise-tax returns, and the public governor disclosure. Each extra filing is another deadline that can be missed, another piece of correspondence sent to a US address you may not monitor closely from abroad, and another reason an account could fall out of good standing. For someone managing the entity across time zones and language barriers, fewer moving parts is not a minor convenience — it is risk reduction.

For a founder living abroad whose only US footprint is the LLC itself, none of Washington's supposed perks (no income tax, Seattle ecosystem) are reachable, while all of its costs are. Wyoming gives you the same federal treatment with lower, flatter, more private state mechanics.

When Washington genuinely wins

Honesty matters, so here is where Washington is the correct choice rather than a mistake.

Washington wins when you actually operate in Washington. If you live in Seattle, Tacoma, Spokane, or anywhere in the state, employ people there, hold inventory in a Washington warehouse, or have a physical office, you have nexus and you must register and pay B&O regardless of where the LLC is formed. In that situation a Wyoming LLC does not save you the B&O tax — it just adds a second filing (a foreign registration in Washington) on top of it. Forming directly in Washington is cleaner and cheaper.

Washington also wins for high-margin service businesses based in the state that value no personal income tax. A profitable consultant or software founder living in Washington keeps far more than they would in California or Oregon, because Washington has no tax on ordinary personal income at all. The B&O hit on a high-margin firm is a small fraction of what a state income tax would take. For a US-resident founder physically in Washington, that trade can be genuinely attractive.

Finally, Washington can win on credibility for certain local relationships — a Washington address and registration can matter for state contracts, local licensing, or partnerships with Washington institutions that prefer an in-state vendor.

What does not qualify as a reason for a non-resident: the absence of personal income tax. Non-residents abroad pay no US state income tax on a properly structured pass-through with no US-source effectively connected income anyway, so Washington's headline benefit is something a Wyoming founder already enjoys — without the B&O tax, without the public ownership disclosure, and at a lower annual cost. If you have no physical Washington presence, the "Washington wins" column is essentially empty.

Real 5-year total-cost projection

This is where the difference becomes concrete. The table below models a non-resident-owned, single-member LLC over five years at four annual revenue levels. Assumptions and 2026 figures, all verified:

• Wyoming: year-one formation $397 all-inclusive (WyomingLLC.xyz, Wyoming state fee included); annual report $60/year in years 2–5; no income, franchise, or gross-receipts tax (Wyoming Secretary of State).
• Washington: Certificate of Formation $200 online, which is $180 plus a $20 processing fee (Washington Secretary of State); registered-agent/service comparable at roughly $200 year one is folded into a $447 year-one figure to mirror the comparison table; Annual Report $70/year, raised under WAC 434-112-085(7) (Washington Secretary of State). No personal income tax. B&O modeled at the Service & Other Activities rate of 1.5% for businesses under $1 million of prior-year taxable income, effective since October 1, 2025 (Washington Department of Revenue). The B&O figures below assume the revenue is Washington-attributable; a true non-resident with no Washington nexus would owe $0 B&O but also has no reason to form in Washington. The column shows what the Washington structure costs if the activity touches Washington, which is the realistic scenario for anyone choosing the state on purpose.

Wyoming totals $637 across all four revenue levels — $397 year one plus $60 × 4 — because nothing in Wyoming scales with revenue. Washington's fee total is $727 ($447 year one plus $70 × 4), already higher than Wyoming on fees alone. But the structural story is the B&O column: at $50,000 of annual service revenue the B&O tax adds $750/year ($3,750 over five years); at $250,000 it adds $3,750/year ($18,750 over five years). A retailing or wholesaling business would be taxed at the lower 0.471% / 0.484% rates instead of 1.5% (Washington Department of Revenue), but it would still pay on gross — there is no $0 outcome once revenue is Washington-sourced. Note Washington's economic nexus standard: more than $100,000 of cumulative Washington receipts in a year creates a B&O filing obligation even without physical presence (Washington Department of Revenue). Wyoming's line is flat at every column. That flatness is the entire value proposition for a non-resident.

For non-residents specifically

Four things matter more to a founder living abroad than to a US resident: banking, privacy, asset protection, and federal reporting. Here is how Washington vs Wyoming plays out on each.

Banking. US fintech business accounts — Mercury, Relay, and Brex among them — are reachable by non-residents with a US LLC, an EIN, and verified ownership documents. Neither state blocks this, but the path is smoothest where the formation paperwork is clean and the EIN is obtained correctly. Wyoming is the more familiar entity type to these onboarding teams simply because so many non-resident founders use it, which can mean fewer review questions. The bank cares about your EIN, your formation documents, and your beneficial-owner ID — not the state's tax code. One practical note: most of these providers want a clear description of your business and the countries you operate from, and they verify the same beneficial-owner identity regardless of formation state, so neither Wyoming nor Washington gives you a shortcut around know-your-customer review. What matters is that your name on the LLC documents matches your passport exactly and your EIN letter is the official IRS CP 575 or 147C.

Privacy. Covered above, but it bears repeating in the non-resident context: Washington publishes your governors (members/managers) on the annual report (Washington Secretary of State). Wyoming does not put your name in the public record at all. If keeping ownership off searchable databases is part of why you are forming offshore-of-your-home-country, Wyoming is structurally better.

Asset protection. Wyoming's sole-remedy charging-order statute, applied even to single-member LLCs, is the strongest in the country. For a founder whose entire US presence is one LLC, that statutory clarity is worth more than Washington's ordinary protection.

Form 5472 and the federal reporting that actually matters. This is identical in both states and is the report most non-residents underestimate. A foreign-owned single-member LLC is treated as a disregarded entity that must file Form 5472 attached to a pro-forma Form 1120 every year, reporting reportable transactions between the LLC and its foreign owner. The IRS penalty for failing to file, filing late, or filing a substantially incomplete 5472 is $25,000 (IRS, "About Form 5472" and Instructions for Form 5472). This obligation exists no matter which state you pick, and it is unrelated to whether you owed any tax. Separately, payment processors issue Form 1099-K only when you exceed more than $20,000 in payments AND more than 200 transactions — the planned $600 threshold was repealed by the One Big Beautiful Bill Act, so the older, higher threshold stands (IRS, "Understanding your Form 1099-K"). Whether a US treaty reduces withholding on any US-source income depends on your country of residence; the authoritative list is IRS Publication 901, "U.S. Tax Treaties" (IRS treaty list). None of these federal points favor Washington over Wyoming — they are the same — which is exactly why the cheaper, flatter, more private state wins on the variables you can control.

Step-by-step forming from abroad

You can form either entity entirely online without setting foot in the US. Here is the Wyoming path, which is the one most non-residents should take.

1. Pick the name and confirm availability. Search the Wyoming Secretary of State business database to confirm your desired LLC name is free, and that it ends in "LLC" or "Limited Liability Company."

2. Appoint a Wyoming registered agent. A registered agent with a physical Wyoming address is mandatory. With the WyomingLLC.xyz $397 all-inclusive package, the registered agent and the Wyoming state filing fee are both included, so this step is handled for you.

3. File the Articles of Organization. This creates the LLC with the Wyoming Secretary of State. As a non-resident you do not need a US address of your own or an SSN to be the member; the registered agent's address serves the public record.

4. Get the EIN from the IRS. Without an SSN or ITIN, you obtain the EIN by faxing or mailing Form SS-4 to the IRS and writing "Foreign" in the box for the responsible party's taxpayer ID. The online EIN tool requires a US taxpayer ID, so the SS-4 route is the standard non-resident method (IRS, "Apply for an Employer Identification Number"). Processing typically takes a few weeks by fax.

5. Decide on an ITIN if you actually need one. Many non-resident LLC owners do not need an ITIN to operate or to open a fintech business account; the EIN does the heavy lifting. If your situation does require one — certain treaty claims or personal US filings — WyomingLLC.xyz offers ITIN handling as a separate $297 add-on rather than bundling a cost you may not need.

6. Open the business bank account. With the EIN letter, formation documents, and your passport, apply to Mercury, Relay, or a comparable non-resident-friendly provider.

7. Set up the annual cadence. File the Wyoming annual report each year ($60 minimum) and prepare the federal Form 5472 + pro-forma 1120 ahead of its deadline. Calendar both immediately so neither lapses.

A Washington formation follows the same arc but adds the public governor disclosure on the Initial Report and, if you have Washington nexus, a Washington Department of Revenue business registration and B&O filings.

Common mistakes

Treating "no income tax" as "no tax." Washington's headline is true and irrelevant for low-margin businesses: the B&O tax bills gross receipts, so you can owe in a loss year. Founders who choose Washington for the income-tax line and never read the B&O line get a nasty surprise.

Forming in Washington while having no Washington presence. If you are abroad with no Washington nexus, you get the higher fees and the public disclosure but none of the local benefits — and you may still owe B&O once Washington receipts cross $100,000. This is the worst of both worlds.

Forming in Wyoming while actually operating in another state. The mirror error. If you have employees, an office, or inventory in California, New York, or Washington itself, a Wyoming LLC does not exempt you — you must foreign-qualify and pay that state's taxes anyway, now with two filings instead of one.

Skipping Form 5472. The single most expensive mistake for non-residents. The penalty is $25,000 per year, it applies even when no tax is due, and it has nothing to do with which state you chose (IRS, Instructions for Form 5472). Many founders form the LLC, open a bank account, and never learn this report exists.

Assuming you need an ITIN to start. You usually do not. The EIN — obtained via the SS-4 "Foreign" method — is what banks and the IRS want first. Buying an unnecessary ITIN up front wastes money and time; treat it as an add-on only when a specific filing demands it.

Forgetting the annual report. In both states the LLC lapses if you skip the annual filing. Wyoming's is $60; Washington's rose to $70 (Washington Secretary of State). Put it on a recurring calendar the day you form.
