A Danish Freelancer Opens a Wyoming LLC from Copenhagen — Full 2026 Walkthrough

Forget abstract guides for a moment. This is about Mads, a B2B SaaS founder in Copenhagen, and how he actually set up a Wyoming LLC in 2026. He went from signing a contract with a US client to having a live USD balance in Mercury, all within two weeks. Mads runs a lean, two-person B2B SaaS operation, selling straight into the US mid-market – a fairly common profile for folks in Denmark that Wyoming LLCs fit like a glove.

The moment the old setup just wasn't cutting it anymore

Mads started out with an enkeltmandsvirksomhed for a couple of years, then upgraded to an ApS once the revenue started looking good. Danish clients were never an issue, payments came through smoothly. Then the US opportunities started popping up: a mid-market US SaaS company wanted to bring Mads on as a vendor.

Their procurement team asked for a W-9. His ApS could only offer a W-8BEN-E, which kicked off a treaty review. That meant a bunch of emails back and forth, dragging out the onboarding process for about six weeks before he could even send the first invoice. On top of that, every SWIFT wire from his smaller US clients before this had been eaten alive by correspondent bank fees and really steep FX spreads. It became crystal clear he needed a US entity.

Wyoming over Delaware, because details matter

Initially, Mads thought about Delaware, because that's what everyone seems to mention first for US companies. But two key things tipped the scales toward Wyoming:

• Delaware charges a minimum $300 annual franchise tax for an LLC, plus a separate Registered Agent fee. Wyoming doesn't do that.
• Wyoming keeps LLC member and manager details private. Mads's CVR filing in Denmark was already public, so stacking more public transparency on the US side just felt like overkill.

Day 0 — Getting Started

Mads hit our Denmark landing page, picked the BASIC + IRS Filings package, priced at $849, state fees all included. He filled out the onboarding form in about 18 minutes. What did he need? Pretty straightforward stuff:

• Three potential LLC names, listed by preference.
• A scan of his Danish passport and proof of address (a utility bill was fine, or a folkeregister extract works too).
• A quick two-sentence summary of his business and how much US revenue he expected in the first year.

No CPR-nummer, no Skattestyrelsen filing, definitely no trip to an embassy required.

Day 1–2 — LLC is Live

The Wyoming Secretary of State sent back a proper Filing ID within 40 hours. Our Wyoming Registered Agent service kicked in on the same day. He got the Operating Agreement, drafted especially for a single-member Danish owner, in his inbox on Day 2 for an e-signature.

Day 3–4 — EIN in Hand

The EIN application went off to the IRS SS-4 international line the very day the Operating Agreement was signed. The confirmation letter, known as CP-575, showed up in under 48 hours. Mads, the Danish beneficial owner, never had to talk to the IRS directly. That's a relief.

At this point, his company was fully established: a US business with its own federal tax ID, completely owned by a Danish tax resident, and zero required trips to the US. That's a win.

Day 5–10 — Mercury Bank Onboarding

Mercury's onboarding form asked for exactly what we said it would: passport, his Danish proof of address, the Wyoming Articles of Organization, the EIN letter, the Operating Agreement, a short description of the business, and his projected monthly transaction volume. Approval came through on Day 9. Virtual debit card was live that same day. The physical debit card got shipped to his Copenhagen address the following week.

Day 11 — First US Client Invoice

The afternoon Mercury was approved, Mads sent his US SaaS customer a W-9. Their procurement team got him set up as a vendor in under 48 hours. Remember, that's compared to the six weeks the ApS route would have taken. First invoice went out on Day 11, and the ACH payment landed on Day 15. That's real money in the bank.

What year-end looked like

For a single-member Wyoming LLC owned by a Danish resident, year-end really isn't a big deal:

• Wyoming Annual Report? We handled it.
• Form 5472 and a pro-forma 1120? Filed by us under the BASIC + IRS Filings plan.
• Danish personal tax return? Mads's tax adviser, registered with Skattestyrelsen, handled reporting the distributions he received and ran the CFC-regler screening. Because his LLC's income was active, it thankfully avoided those harsh CFC outcomes.

Would Mads go through with it again? You bet.

Here are two solid numbers from Mads's first year:

• Enterprise procurement speed-up: he saved roughly four weeks per US customer onboarding, on average.
• Savings on FX and wire fees for incoming USD: easily high three digits USD every quarter, even with a moderate revenue stream.

Both of those figures, just by themselves, paid back the first-year package cost several times over. The much bigger operational benefit – being able to close US enterprise deals at the same speed as his competitors – is tougher to put a number on, but it certainly showed up in his sales pipeline.

If you see yourself in Mads's story

If you're a Danish tax resident, have US customers knocking on your door, and your ApS works fine for Denmark and EU/EEA income, then a Wyoming LLC is probably a great fit for you too. Dig into these articles for more depth:
