A Finnish Founder Opens a Wyoming LLC from Helsinki — Full 2026 Walkthrough

Forget those wishy-washy guides. This is about Aino, a Helsinki-based mobile-game developer, and how she got her Wyoming LLC up and running in 2026. She went from signing a contract with a big US client to seeing a live USD balance in her Mercury account, all within two weeks. Aino’s a solo indie dev, pumping out games for iOS and Android worldwide. It’s a common story for Finnish founders, and it fits the Wyoming LLC model like a glove.

Why the Oy-only setup started to feel like a drag

Aino had cruised along with a toiminimi (Tmi) for a couple of years, then upgraded to an Oy once the cash flow looked healthier. Domestic clients were a breeze. Then, out of the blue, a US pipeline opened up. A mid-market US SaaS company wanted to bring Aino in as a vendor.

Their procurement team asked for a W-9. Her Oy could only cough up a W-8BEN-E, which meant a treaty review. That sparked a flurry of emails back and forth, putting a six-week hold on things before she could even send an invoice. Meanwhile, every SWIFT wire from those smaller US clients she’d had before was getting eaten alive by correspondent-bank fees and nasty FX spreads. It became crystal clear: adding a US layer to the business just made financial sense.

Wyoming won out over Delaware, and here’s why

Aino did a quick glance at Delaware, because, let’s be honest, everyone talks about Delaware. But two things made her swing to Wyoming instead:

• Delaware hits you with a $300 minimum LLC franchise tax every year, plus another fee for your Registered Agent. Wyoming doesn't do that.
• Wyoming keeps LLC member and manager names private. Aino, as a Finnish tax resident, already had her YTJ / Kaupparekisteri filings out in the open domestically. Slapping that same level of transparency on the US side just felt… redundant.

Day 0, when it all began — onboarding

Aino hit up the Finland landing page, picked the BASIC + IRS Filings package, which was $849, state fees included, and filled out the onboarding form. Took her about 18 minutes. She needed a few things:

• Three potential LLC names, just in case her first choice was taken.
• A scan of her Finnish passport and something to prove her address, like a utility bill. A väestörekisteri extract would’ve worked too.
• A quick two-sentence summary of her business and a rough idea of what she expected to make in US revenue that first year.

No henkilötunnus, no Verohallinto forms, no trekking to an embassy. Easy.

Day 1–2 — LLC officially live in Wyoming

The Wyoming Secretary of State churned out a real Filing ID in under 40 hours. The Wyoming Registered Agent got activated the very same day. Her Operating Agreement, specially written for a single-member Finnish owner, landed in her inbox on Day 2, ready for e-signature.

Day 3–4 — EIN issued, just like that

The EIN application went straight to the IRS SS-4 international line the same day she signed the Operating Agreement. That confirmation letter, the CP-575, showed up in under 48 hours. Aino never had to speak with the IRS directly, which was a relief.

At this point, her company was fully legal: a US entity, with its own US federal tax ID, 100% owned by a Finnish tax resident, without her ever needing to step foot in the US.

Day 5–10 — Mercury account, good to go

Mercury’s onboarding form asked for exactly what they said it would: passport, proof of her Finnish address, the Wyoming Articles of Organization, the EIN letter, her Operating Agreement, and a short business description with projected monthly revenue. Approval rolled in on Day 9. Her virtual debit card was ready that same day. The physical card was shipped to her Helsinki address the following week.

Day 11 — first invoice to a US client

Aino shot a W-9 over to her US SaaS customer the very afternoon Mercury gave the green light. Their procurement team got her set up as a vendor in under 48 hours. Remember, the Oy route was looking at six weeks. She sent her first invoice on Day 11, and the ACH payment hit her account on Day 15.

What year-end looked like for Aino

Year-end for a single-member Wyoming LLC with a Finnish owner is surprisingly straightforward:

• Wyoming Annual Report: We took care of that.
• Form 5472 + pro-forma 1120: Also handled by us under the BASIC + IRS Filings plan.
• Finnish personal tax return: Aino’s Verohallinto-registered adviser reported her received distributions and did the väliyhteisölaki screening. The LLC’s active-income status kept it from getting tangled in any harsh CFC issues.

Would Aino do it all again? Absolutely.

Two solid data points from Aino’s first year tell the story:

• Enterprise procurement speed. She saved about four weeks on average for each new US customer she onboarded.
• Savings on FX and wire fees for incoming USD. That added up to a solid high three-digit dollar amount every quarter, even on a moderate revenue base.

Both those numbers alone easily covered the first year’s package cost many times over. The bigger win, though, was being able to close US enterprise deals at the same speed as her competitors. That’s harder to put a number on, but it certainly showed up in her pipeline.

If you’re in Aino’s shoes

If you’re a Finnish tax resident, already have some US customers lined up, and your Oy works fine for Finland and EU/EEA revenue, then a Wyoming LLC is probably a good fit for you too. Dive deeper with these reads:
