LLC, sole prop, or e-residency: choosing your billing entity as a nomad

You invoice a US corporate at $12,000 a month and an EU SaaS company at €4,500. You have a Georgian tax certificate, a Wise account, and a Tallinn mailing address. But when a procurement manager asks "what entity are we paying?", the answer still makes you pause.

Choosing a billing entity is not a one-time decision you make when you set up a bank account. It is the load-bearing wall of your whole financial setup. Get it wrong and you pay tax twice, lose a contract because you cannot issue a compliant invoice, or trigger a permanent establishment problem in a country you passed through for six weeks.

Here is how to think through the three structures most nomad consultants actually use.

What "billing entity" actually means for you

Your billing entity is the legal person that signs contracts, sends invoices, holds the bank account, and files the tax return. It is not your tax residency (where you are personally taxed) and it is not your banking country (where your IBAN lives). These three things can be, and often are, in three different countries.

The confusion between them is where most nomads get into trouble. A client's accounts payable department does not care about your personal tax residency. They care that your invoice has a registered company name, a valid address, and a tax ID they can file against.

The three questions that decide the structure

Before you pick a structure, answer these honestly:

• Who are your clients? US-only clients often prefer a US entity (LLC or S-corp). EU clients want a VAT number or at least an EU-adjacent entity.
• What is your personal tax situation? If you are genuinely non-resident everywhere, a foreign entity with no local PE is clean. If you have a home base, your local rules dominate.
• How much do you earn? Below $60k USD equivalent a year, the overhead of a full corporate structure rarely pays back. Above $120k, it almost always does.

Sole proprietorship: the zero-friction starting point

A sole prop means you invoice as yourself. No company registration, no corporate bank account, no annual filings beyond your personal return.

For a nomad consultant billing $8,000 a month or less, this is often the right answer for the first year or two. Setup takes a day. You can open a Wise or Revolut account under your own name in hours. And clients that pay under $10,000 a year to a single contractor rarely care whether they are paying a company or an individual.

The real limits show up here:

• Some enterprise procurement departments will not pay individuals. They need a company name on the invoice and a W-9 or W-8BEN equivalent.
• Liability is unlimited. If a contract dispute goes sideways, your personal assets are on the table.
• Once you cross $80k–$100k equivalent, the self-employment tax or equivalent in your home jurisdiction starts to sting badly enough that a structure review is overdue.

When to move on

If you have just lost a $15,000 contract because procurement would not onboard an individual, that is your signal.

US LLC: the nomad's most common upgrade

A US single-member LLC (typically Wyoming or Delaware) is the most popular step up for nomad consultants who bill US clients. Here is why it works:

• Clients recognise it immediately. Fortune 500 procurement, media companies, and US-based startups all have an onboarding flow for LLCs. You get a W-9 filed, an EIN assigned, and payments release without delay.
• Tax treatment is pass-through by default. A single-member LLC is a "disregarded entity" for US federal tax. You report the income on your personal return. If you are a non-US person with no US-source income and no effectively connected income, a properly structured Wyoming LLC can be tax-neutral at the federal level (confirm this with a US international tax advisor, not a Reddit thread).
• Banking is straightforward. Mercury, Relay, and similar fintechs open US business accounts remotely for LLCs, often in 48 hours.

The friction points:

• Annual state fees ($50–$300 depending on state), a registered agent (~$100–$200/year), and a US business address service.
• If you have EU clients who want a VAT number, a US LLC gives you none. You would invoice them without VAT and they apply reverse-charge on their end, but you need to invoice correctly for that to work.
• If you ever spend significant time in the US, you may create a US tax nexus. Track your days carefully.

Estonia e-residency and the OÜ: the EU invoice machine

Estonia's e-residency programme lets you incorporate an Estonian private limited company (OÜ) without living there. The card arrives by mail, you sign everything digitally, and your company has a valid EU VAT number within a few weeks of incorporation.

For a nomad consultant with a mix of EU and global clients, this is a genuinely useful structure:

• EU VAT number. You charge VAT on EU consumer sales, apply reverse-charge correctly on EU B2B invoices, and issue compliant invoices that European accounts payable teams process without escalation.
• Corporate tax deferral. Estonia taxes only distributed profits, not retained earnings. If you reinvest or accumulate inside the company, you pay 0% corporate tax until you pay yourself a dividend.
• Digital infrastructure. Company registration, annual reports, and tax filings are all online. Leapin, 1Office, or similar service providers handle the registered address and accounting for €100–€300 a month.

Where it gets complicated:

• You still need personal tax residency somewhere. The OÜ pays Estonian corporate tax on distributions, but your personal dividend income is taxed where you are personally resident. E-residency is not a tax residency.
• Banking for an Estonian OÜ as a non-EU resident has become harder since 2020. LHV and Swedbank are selective. Wise Business, Revolut Business, and Stripe are more accessible but not identical to a full business bank account.
• If your home country decides you are running the company from there (management and control test), they may tax it locally regardless.

Combining structures

Some nomad consultants run both: a US LLC for North American clients and an Estonian OÜ for EU clients. The added overhead (two sets of filings, two bank accounts, careful invoicing from the right entity) is real, but so is the ability to issue the right invoice to every client without friction.

Getting the invoicing right regardless of entity

Whichever structure you choose, your invoice has to match it exactly. The entity name, registered address, and tax ID on the invoice must be the ones your client's accounts payable team has on file. A mismatch delays payment and, with large clients, can trigger a reissuance request that costs you 30 days.

A few things that matter in practice:

• Reverse-charge VAT for EU B2B. If you are invoicing a German GmbH from your Estonian OÜ, the invoice should state "Reverse charge: VAT to be accounted for by the recipient" and show 0% VAT. Getting this wrong means you either collect VAT you are not registered to remit, or you leave the client unable to reclaim input tax.
• Payment terms as a cash flow lever. A US LLC billing a US corporate on Net 60 is a 60-day float you are funding. Setting Net 30 as your default and noting it explicitly on every invoice is table stakes. Some clients will push back. Many will not.
• Consistent reference numbers. If you are invoicing from two entities, keep the numbering sequences separate and clearly prefixed (US-2025-001, EE-2025-001). Your own sanity and your accountant's sanity both depend on it.

The decision in plain terms

Pick sole prop if you are under $80k equivalent a year, your clients are flexible about paying individuals, and you want zero overhead while you find your client base.

Pick a US LLC if most of your revenue comes from US clients, you want a recognised entity for procurement onboarding, and you are comfortable with pass-through taxation.

Pick an Estonian OÜ (or add one) if a meaningful share of your revenue is from EU clients who need a VAT-compliant invoice, and you want to defer corporate tax on retained profits.

The entity does not fix your tax residency question. That is a separate conversation with a cross-border tax advisor who knows both your home jurisdiction and your target entity jurisdiction. But getting the entity right means you stop losing contracts to procurement friction and start getting paid on the terms you actually negotiated.
