Card payments from customers worldwide
Stripe already supports Belgian businesses, and a BV or SRL is what Belgian banks and the tax office understand.
From Belgium · Europe
For Belgian founders who sell into the US as a US vendor or raise from US investors. A Belgian BV or SRL already gets you Stripe, and Mercury and Wise Business both serve founders here. A US company managed from Belgium is Belgian-resident, and the Cayman tax can reach a low-taxed one, so read that section first.
Launch + Wyoming filing; the tax return is separate.Checked by Saais Patel, compliance reviewer.
At a glance
Mercury takes applications from founders living in Belgium. Wise Business is the usual second account.
The banks, in detailYou can form a US company while living in Belgium, without an SSN or a US visit, and Mercury and Wise Business both open for founders here. Launch starts at $351.40 in Wyoming, including our plan and state filing fee. A Belgian BV or SRL already gets you Stripe, so the reason is usually US customers or investors. The Belgian points: a company managed from Belgium is Belgian-resident, the Cayman tax can reach a low-taxed one, and accounts abroad are reported to the National Bank.

Watch
Thinking of a US LLC while living in Belgium? For card payments you may not need one: Stripe already supports businesses in Belgium, and a Belgian BV or SRL gets you it too.
Before you form
Wyoming LLC
Owner-run business selling to US customers, after advice.
Delaware C-Corp
Raising from US investors; plan where it's managed.
Both charges are the state's, before our plan, optional services and your advisers' fees. Wyoming sets a minimum yearly charge, and Delaware's franchise tax depends on how it's calculated. Staff, stock or premises in another state can bring obligations there. An S-corporation isn't an option, because nonresident aliens can't hold its shares.
Prepare the information
You don't need a Belgian company to form a US company. The EIN is the US company's tax ID. Send identity documents through a secure request, and only the ones asked for.
How it works
The state approves the company, the IRS issues the EIN and each provider approves its own account. In Belgium, your tax adviser handles the return and you report accounts abroad; we don't file there.
You and your tax adviser
Decide whether you need a US company at all, where it will be managed, and whether the Cayman tax could reach it.
You leave this stage with: A structure and tax plan that fits Belgium's rules.
You choose; BaseAcross checks
We check the proposed name and provide the registered agent in the formation state. The registered office is for legal papers, not your operating address.
You leave this stage with: Confirmed filing details and a registered agent.
BaseAcross files; the state approves
We submit the formation filing and send you the state's documents once it's approved. The company exists from that approval.
You leave this stage with: State-approved formation documents.
BaseAcross
We draft the LLC Operating Agreement or corporate bylaws. Check every name and share against your passport before you sign.
You leave this stage with: Operating documents for your records, your bank and US providers.
BaseAcross prepares; the IRS issues
The EIN is a separate application after formation. Without an SSN or ITIN, it goes on Form SS-4 rather than the IRS's online tool.
You leave this stage with: The IRS's EIN confirmation once it's issued.
You apply; the providers review
Start with Mercury or Wise Business, which both serve founders living in Belgium. Use the same names, addresses and business description everywhere.
You leave this stage with: An approved account, if a provider accepts the application.
You, your US preparer and your tax adviser
Keep the company's books, and minutes showing where decisions are taken. Put Form 5472, any account report and your Belgian return on one calendar.
You leave this stage with: A yearly calendar with someone responsible for each filing.

Published service estimates and prerequisites for a Wyoming company from Belgium
These are service estimates, not promised completion dates. The IRS and each provider set their own processing times. Names or addresses that differ between documents slow every stage.
What it costs
Charged in US dollars, with the Wyoming state fee passed on at cost. Where you live changes which bank we introduce you to, not the price.

State filing serviceArrange separately
You or your accountant handle Form 5472 and any other US returns on Launch and Operate. Ask the preparer for their scope and fee.
Federal filing responsibilitiesQuote from your tax adviser
Where the LLC is managed, whether the Cayman tax reaches it and how it pays you depend on your circumstances.
Published in full pricing
Check domain renewals and when Launch's email, phone and site trials end. Operate includes its stated tools while subscribed.
Plans, trials and add-onsThe $309 Launch renewal example is the $249 plan renewal plus Wyoming's $60 minimum license tax. Wyoming charges the greater of that minimum or 0.0002 of the company's assets located and employed in the state, and paying online can add a processor fee. The Operate example uses the same minimum.
Prices are in US dollars. Paying from Belgium, check your card's exchange rate and fees.
Use the first-year cost calculator to compare plans and optional tools. Then add your tax adviser's fees and US return preparation to that budget.

What changes because you live here
1 of 4: The tax treaty
The tax treaty
The US–Belgium income tax treaty is in force.
It exempts interest and royalties from US withholding, and caps dividends at 15%, or 5% for a qualifying company shareholder. Pay for work you do in Belgium generally isn't US-source income, so the treaty matters less for a services business.
How Belgium sees it
Residence, rates and the Cayman tax come from PwC's summary; the account rule from the National Bank of Belgium. They run alongside the US steps below.
The company, with your tax adviser
Belgian-resident and taxed at 25%, or 20% on the first €100,000 for a qualifying small company.
You
The Cayman tax can tax its income to you before it pays you, and your return must mention it.
You
Report it once to the National Bank's Central Point of Contact, and mention it on every return.
Worked example
This is an illustration, not a quote. The small-company conditions and the surcharge are for your tax adviser.
Your Wyoming LLC makes €100,000 of profit, and you take its decisions in Brussels.
Its seat of management is in Belgium, so it's Belgian-resident.
At 25%, its corporate tax is €25,000. If it qualifies as a small company, 20% on that first €100,000 makes it €20,000.
How it then pays you, as salary or dividends, is a separate question for your adviser.
What Belgium expects
Belgium treats a company managed from there as resident and taxes it at 25%, can tax you on a low-taxed entity's income through the Cayman tax, and wants accounts abroad reported to the National Bank.
A company whose principal place of business or seat of management is in Belgium is Belgian-resident, wherever it was formed. The seat of management is where its decisions are actually taken.
Corporate tax is 25%. A small company that meets several conditions pays 20% on its first €100,000 of profit. A surcharge applies unless enough tax is paid in advance.
Belgium can tax you on the income of certain legal constructions you founded, including low-taxed or untaxed foreign entities, before any of it is paid out. Your return must mention such a construction each year, with a detailed annex since 2024.
Report each account you hold or co-hold abroad to the National Bank's Central Point of Contact by the time you file your return. You report it once, plus later changes, and your return mentions it every year. A power of attorney alone doesn't need reporting.
You're resident if your home is in Belgium or, without one, your centre of economic interests. Being on a commune's population register makes you presumed resident.
On the record
We form US companies. We aren't Belgian tax advisers. These are the rules as they're generally published, they change, and how they apply to you depends on details this page can't know. Take this list to a tax adviser in Belgium before you order, and we'll tell you what the US forms need.
After formation
A US LLC with one foreign owner is usually a disregarded entity that files Form 5472 with a pro forma Form 1120 when it has reportable transactions with you. Money you put in, take out or are paid for your work can count even in a year without sales. The IRS penalty for not filing starts at $25,000.
For a calendar-year company, the return is usually due 15 April, and Form 7004 requests an extension before then. A C-Corp, or an LLC with more than one owner, files different returns.
Form 5472 and the pro forma 1120Keep the registered agent active and track the state's yearly charge. In Belgium, mention accounts abroad and any legal construction on your return, report new accounts to the National Bank, and expect corporate returns if it's managed here.
US-created companies are exempt from BOI reporting under FinCEN's current rule, effective 14 August 2026. Banks and payment providers still verify who owns the company.
| Task | Who handles it | Where the responsibility ends |
|---|---|---|
| Formation and EIN application | BaseAcross prepares and submits | The state approves formation; the IRS issues the EIN. |
| Bank and payment applications | You, with our guidance | The provider verifies the information and decides. |
| Belgian return and account reports | You and your tax adviser | We provide the US company records they need. |
| Annual state filing | You, or our optional filing service | Reminders are included; managed filing and the state charge are separate. |
| US federal returns | You and your US tax preparer | Launch and Operate remind you; they don't file the return. |

Questions
If yours is not here, email us at hello@baseacross.com before you order.
Yes. US law doesn't require an LLC's owners to be US citizens or residents, and formation, the EIN and the bank applications all happen remotely. The Belgian questions are where it's managed, the Cayman tax and reporting your accounts abroad.
It can. A company whose principal place of business or seat of management is in Belgium is Belgian-resident, wherever it was formed. The seat of management is where its decisions are actually taken.
Corporate tax at 25%. A small company that meets several conditions pays 20% on its first €100,000 of profit. A surcharge applies unless enough tax is paid in advance.
It taxes a Belgian resident on the income of certain legal constructions they founded, including low-taxed or untaxed foreign entities, before any of it is paid out. Your return must mention such a construction each year. A single-owner LLC pays no US tax of its own, so ask your adviser whether it counts.
If you hold an account abroad, yes. Report it to the National Bank's Central Point of Contact by the time you file your return, once, plus later changes, and mention it on your return every year. A power of attorney alone doesn't need reporting, so ask your adviser whether the LLC's account counts as yours.
Launch starts at $351.40: $249 for the plan plus $102.40 for the Wyoming filing. The plan and Wyoming's minimum yearly charge then total $309 a year. Your tax adviser's fees, US return preparation and Belgian filings are separate. Wyoming's license tax can be more than its $60 minimum.
A Wyoming LLC suits an owner-run business selling to US customers, once you know whether the Cayman tax reaches it. A Delaware C-Corp suits raising from US investors. Nonresident aliens can't hold shares in an S-corporation.
Yes. Without an SSN or ITIN, the application goes on Form SS-4 instead of the IRS's online tool. We prepare it after the company is formed, and the IRS issues the number.
Each stage has its own clock. Wyoming's published turnaround is same day once a complete filing is accepted. Our ordinary EIN estimate is six to eight weeks after the application, or two to three weeks with the $199 expedited option. Banks, payment providers and Stripe each set their own review times. These are estimates, not promises.
Usually you can apply. Belgium isn't on Mercury's list of countries it doesn't serve, and the list goes by where you live. Mercury still reviews each company and can decline.
Usually, yes. Belgium is on Wise's list of places where people can hold money, so a US company run from Belgium can get USD account details. Wise reviews each business.
No. Stripe supports businesses in Belgium, and a BV or SRL gets you Stripe too. A US company is for selling as a US vendor, US contracts, US investors or platforms that need one.
Generally not. Pay for work you do in Belgium is generally not US-source income, so a US company with no US office or staff often owes no US income tax on it. A single-owner LLC still files Form 5472 with a pro forma Form 1120 when it has reportable transactions with you.
Yes, it's in force. It exempts interest and royalties from US withholding, and caps dividends at 15%, or 5% for a qualifying company shareholder.
On Launch and Operate, we add deadlines and reminders; you or your accountant file the federal returns. Managed annual state compliance is an optional $149 service fee a year, with the state's charge separate. Your Belgian return and any account report are for you and your tax adviser.
US-created companies are exempt under FinCEN's current BOI rule, effective 14 August 2026. A company formed outside the US and registered to do business there is a different case. Banks still collect ownership details for their own checks.
