When non-residents form a company, they often wonder: Will a UK Ltd or US LLC help me get paid, protect my assets, and stay compliant?
Many founders confuse UK Ltd LLC, thinking they’re the same. But the reality is different when you start dealing with clients, opening accounts, and signing contracts.
A UK private limited company shows stability to UK clients and keeps your personal assets safe. A US LLC makes USD invoicing easier and is familiar to US buyers, even if you’re not in the US.
Be cautious of “$0 LLC” offers online. They often hide the cost of a registered agent, an EIN, and necessary filings, even if you don’t owe US tax.
In this guide, we explore how each structure affects your business: banking, payments, and ongoing duties. We discuss state choices, EINs without SSNs, and using Mercury, Relay, and Wise for accounts. We also talk about payments via Stripe and PayPal and important filings like Form 5472.
It’s important to know: forming a US LLC doesn’t automatically make you a US tax resident. Your tax situation depends on where your income comes from and if your activity is considered a US business.
At Start Company Formations, we focus on making decisions that stand up to scrutiny, not just quick setups. If you want predictable costs and manageable compliance, the UK Ltd vs US LLC question needs a thorough answer.
Who this UK Ltd vs US LLC comparison is for (non-resident founders and global operators)
If you run a business across borders, choosing between a UK company and a US entity matters. It affects payments, paperwork, and how clients see you. This guide is for those who sell internationally and need a structure that fits real trading, not just theory.
It’s also for founders who weigh speed and simplicity against long-term credibility. In practice, banking and card payments often drive the decision as much as tax or legal form.
Freelancers, agencies, SaaS founders, and e-commerce sellers trading internationally
We see strong demand from consultants, studios, and remote teams that sell services worldwide. This includes people comparing a UK Ltd LLC for freelancers with options that better match US-facing work.
It also fits online trading models where platform access matters. If you are setting up an e-commerce LLC, or refining a SaaS company structure, the right entity can reduce friction when you scale into new markets.
Non-residents who want to invoice in USD and look credible to US clients
If your customers are in the States, USD invoicing can cut back-and-forth and speed up approvals in procurement teams. A US LLC for non-residents can also feel familiar to US clients who prefer contracting with a domestic entity.
Payments are a common pressure point too. Many global operators choose a structure that supports Stripe for non-US founders, alongside PayPal, without constant reviews or payout delays.
Founders who need simpler admin, predictable costs, and remote set-up
This is for founders who want to form and run everything remotely, with clear annual tasks and fewer surprises. Predictable running costs, tidy records, and a simple compliance calendar often matter more than edge-case features.
It also suits operators who plan to hold US-based assets, or may explore investor routes where Delaware can come up in conversations. We keep the focus on practical set-up choices that support day-to-day trading and smooth cash collection.
Snapshot comparison for non-residents: credibility, cost, speed, and ongoing compliance
When comparing a UK Ltd and a US LLC, we look at four key areas. These are credibility with clients, how fast you can set up, the day-to-day admin, and the initial cost. For many founders, the main factor is the cost difference between the two over the first year and second year.
Credibility often depends on where you operate. A US LLC might be better for US sales and banking. On the other hand, a UK Ltd suits UK suppliers and contracts better.
Speed is influenced by how quickly you can set up an LLC and get an EIN. State filing times vary, from same-day to 5–15 business days. Non-residents usually plan for 1–3 weeks, then adjust based on EIN speed.
- One-time state filing examples: Wyoming ~ $102, Delaware ~ $108–$110, New Mexico ~ $50.
- Typical state processing: same-day (expedited) to 5–15 business days, before factoring in EIN processing time.
For a US LLC, you must have a registered agent. Most states require one, costing $49–$150 a year. This often explains why cheap adverts don’t match the real cost.
- Registered agent cost: commonly $49–$150/year, depending on provider and state.
Ongoing admin for a US LLC can be different for non-residents. It includes state and federal reports, even if no US tax is due. Missing deadlines can be costly, so keeping to the calendar is crucial.
- Wyoming: annual report around $60 minimum.
- Delaware: franchise tax around $300/year, due 1 June.
- New Mexico: generally $0 annual report requirement.
- Florida: annual report $138.75 due by 1 May, rising sharply if late.
On the federal side, foreign-owned LLCs may need to file Form 5472 with a Form 1120. The penalty for late or missing Form 5472 can be $25,000 or more. This is why we see compliance as a key cost, not an afterthought.
UK Ltd company basics for non-residents (what it is and why people choose it)
Trading across borders can be complex. The structure you choose affects how you get paid and how you’re seen. A UK Ltd company for non-residents is popular because it follows UK rules, even for those who live elsewhere.
It’s a company that can sign contracts, hold assets, and invoice clients. This makes managing the business easier as it grows.
Limited liability and separation between personal and business risk
One big advantage is the limited liability protection. This means the company, not you, is responsible for its debts. This can protect your personal assets if things go wrong.
This is crucial for big deals, long payment terms, or high-value services. With the right setup, your personal assets stay safe.
UK market signalling and counterparties that prefer a UK entity
A UK company signals stability and trust. This can speed up getting started with new clients and make finance teams more confident.
In sectors where UK terms are preferred, a UK company fits well. It supports the business reality, not just a name.
Practical fit for UK-focused trading, suppliers, and contracts
If you mainly operate in the UK, a UK Ltd company makes sense. It helps with setting up accounts, credit terms, and paperwork for goods or services in the UK.
UK customers who want UK contract wording and invoice formats
Supply chains where a UK entity makes onboarding easier
Contracts that rely on UK corporate norms and reporting
Using a UK Ltd company for non-residents makes contracting clearer. It keeps the business separate from the founder. This leads to fewer questions and stronger relationships based on UK norms and protection.
US LLC basics for non-residents: legal ownership and remote formation reality
For many global founders, a US LLC is about clean business infrastructure, not location. As a US LLC non-resident, we can set up a structure for contracts, payments, and operations. This keeps paperwork clear and day-to-day admin manageable.
It also helps to separate personal and business obligations. The limited liability boundary is crucial when working with new clients, larger retainers, or higher order volumes across borders.
Foreign nationals can legally own 100% of a US LLC without citizenship, residency, or a visa
We make this point clear: a foreign national can legally own 100% of a US LLC. You don’t need US citizenship, US residency, or a visa to be the sole member.
In most cases, it is possible to form a US LLC without SSN and still complete a remote LLC formation from start to finish. The key is following the right filing sequence and preparing the documents that banks and platforms expect.
Typical remote timeline of around 1–3 weeks depending on state processing and EIN timing
State filing is often quick, but the real clock is the EIN. That IRS step can extend the timeline, even when the state approves fast.
In practice, we often see an end-to-end remote LLC formation land in roughly 1–3 weeks. This depends on state processing speed and EIN timing. Planning for this window keeps you realistic about when you can start billing and onboarding tools.
Common motivations: USD invoicing, platform access, and smoother cross-border payments
Most non-residents choose a US LLC because it reduces friction in how money moves. USD invoicing can feel simpler for US clients, and it can reduce back-and-forth over exchange rates and payment rails.
Payment stack access, including Stripe LLC set-ups where eligibility and business verification tend to be more straightforward with a US entity
Remote-friendly banking routes, such as a Mercury bank account or a Relay bank account, which can support everyday operations and cleaner reconciliation
Platform expectations for sellers and operators on Amazon and Shopify, where a US entity can fit standard onboarding flows
One nuance matters: forming as a US LLC non-resident does not, by itself, mean automatic US tax. Tax exposure depends on how and where income is sourced, and whether there is a US trade or business in practice.
UK Ltd LLC
“UK Ltd LLC” is often searched but doesn’t mean one thing. It’s really about comparing a UK Ltd with a US LLC. Knowing this early helps avoid delays in trading and working with suppliers.
Understanding the UK Ltd LLC meaning is key. Banks and others check the exact type of entity. If it doesn’t match, things can slow down or stop. So, we make sure you get the terminology right from the start.
Clarifying terms: UK Ltd (company limited by shares) versus US LLC (limited liability company)
A UK Ltd is a company with shares, registered at Companies House. It has directors and shareholders. A US LLC is a limited liability company, formed at state level, with an operating agreement. Both offer limited liability but are managed differently.
When we talk about UK Ltd vs US LLC, we focus on what others see. “Ltd” and “LLC” on invoices and contracts show different governance and expectations. This is key for daily operations.
How “Ltd vs LLC” differences affect contracts, banking, and payments for non-residents
In cross-border contracts, the right entity can speed up approval as a vendor. UK suppliers might prefer a UK entity, while US clients might want a US one. The paperwork can differ, even with the same commercial terms.
Banking and payments are where non-residents feel the difference most. Many choose a US LLC for USD access. Yet, business banking for non-residents requires clear documents and sequencing. If the entity type is unclear, getting set up with Stripe or PayPal can be tough.
Contracts: match the entity to the market you sell into, for cross-border contracts and vendor onboarding.
Banking: expect deeper checks for business banking non-residents, including beneficial owner details and proof of activity.
Payments: the Ltd vs LLC difference can affect how processors classify risk, request evidence, and review payouts.
Compliance effort is not the same. A UK Ltd vs US LLC comparison should include filing requirements and deadlines. For foreign-owned US LLCs, federal reporting can be strict, even with no US tax due.
Formation and set-up: what “fully remote” really looks like in the US for non-residents
When we help clients form US LLC remotely, “remote” means paperwork can be handled online. But the choices still matter. First, pick a state, then confirm the name, file, and collect your approval documents. Getting these steps right is key for banking and payments later.
The LLC name must be unique in the state and usually includes “LLC” or “Limited Liability Company”. We check availability with the Secretary of State search before filing. This name is used in invoices, contracts, and account checks, so it must fit your brand and trade.
State selection as the first fork in the road (Wyoming, Delaware, New Mexico)
Most non-resident founders quickly narrow their choices. A Wyoming LLC non-resident set-up is often chosen for low admin and straightforward upkeep. Delaware is common when a stronger court framework is important. New Mexico can suit lean starts where costs are the priority.
- Wyoming: often chosen for lower ongoing reporting friction and simple state rules.
- Delaware: often chosen for investor familiarity and established corporate case law.
- New Mexico: often chosen for low entry cost, including the New Mexico LLC filing fee.
Registered agent requirement and typical annual cost range ($49–$150/year)
Every LLC needs a registered agent with a physical address in the formation state. They must be available during business hours to receive legal and state notices. For most non-residents, using a professional service is best, not acting personally.
Costs typically range from $49 to $150 per year, and they recur. A Delaware LLC registered agent is a good example of why the “$0 LLC” pitch can mislead: the agent fee is not optional, and it keeps the company in good standing.
Articles of Organisation filing fees and typical processing times (same-day to 5–15 business days)
The LLC is created when the state accepts the Articles of Organisation. In some contexts, you will also hear Certificate of Formation used for the approved state document. Banks may request it in your paperwork bundle. Filing fees vary, and expedited options can change the timeline.
- Typical state fees: Wyoming about $102; Delaware about $108–$110; New Mexico about $50.
- Processing: sometimes same-day with expedited handling, or around 5–15 business days depending on workload.
- Next practical step: store the stamped approval safely, as it is often requested during account onboarding.
EIN for non-residents: the step that most often delays US LLC launch
After a US LLC is approved, getting a tax ID is often the next hurdle. An EIN for non-residents is crucial for daily operations. Yet, it’s easy to overlook how long it takes.
Why you need an EIN for banking, Stripe/PayPal, and federal filings
An EIN is the LLC’s federal tax ID. Banks need it to open a business account. Many legal steps also require it.
It’s also key for payments. Without an EIN, Stripe and PayPal can’t verify your account. This can limit your business’s growth.
How to get an EIN without an SSN: fax, phone, or post using Form SS-4
Non-residents can’t use the IRS online EIN tool because it needs a US ID. So, they must apply for an EIN without SSN using Form SS-4.
We plan for three ways to submit Form SS-4:
- Phone: call the IRS EIN phone number for international callers at +1-267-941-1099 with Form SS-4 ready.
- Fax: fax Form SS-4, keeping a clear copy of what was sent.
- Post: mail Form SS-4 when other options are not available.
Some providers finish state filing but leave the IRS step to the founder. This delay can push back banking and payment plans.
Realistic processing expectations: phone can be same-day; fax commonly 10–15 business days; post 4–6 weeks
Processing time varies by method and IRS workload. Phone service can be immediate if the call is answered correctly. Fax takes 10–15 business days. Post can take 4–6 weeks.
We include the EIN in our launch plan from the start. Begin the EIN process right after state approval. Allow 1–2 weeks for processing. Avoid applying to banks or processors until you have the EIN in writing.
US bank accounts and payment processing: Mercury/Relay, Wise, Stripe, and PayPal
For many overseas founders, getting a US LLC to feel real starts with banking. We usually aim for a remote US bank account first. Then, we connect payments once the account is live.
Traditional banks like Chase and Wells Fargo often need you to visit in person. They also ask for extra checks. This can slow down trading if you’re managing everything from the UK.
Remote-friendly options versus traditional banks that often require in-person visits
Most non-residents prefer fintech options because they are online. A Mercury bank non-resident LLC application works well if your documents are tidy and consistent.
A Relay bank account LLC is also popular. It’s great for keeping income, tax set-asides, and contractor spend separate. Many teams find it helps with cash control.
Founders also add a Wise Business USD account to receive USD and pay suppliers easily. It can help with a US account, but it’s not always seen as a full replacement for US banking by every platform.
Typical document bundle: Certificate of Formation, EIN letter, Operating Agreement, passport
Providers do KYC and AML checks, so the paperwork is similar. We prepare the core bundle before you apply:
- Certificate of Formation or stamped Articles of Organisation
- EIN confirmation letter
- Operating Agreement (often requested even when it is not filed)
- Valid passport
You may also need proof of address, beneficial owner details, and source-of-funds information. Keeping names, addresses, and dates consistent helps avoid delays.
Key pitfall: applying before the EIN arrives often triggers rejection
The biggest mistake is applying too early. If you start Mercury, Relay, or payments onboarding before the EIN is issued, automated checks can fail. This can be hard to reverse.
Once your bank account is active, Stripe for non-US founders is easy to apply for. You need the EIN and US bank details. The same goes for PayPal US LLC, where identity and entity matching are strict.
US LLC tax exposure for non-residents: ECI, FDAP, and what can trigger US tax
Founders often wonder about US LLC tax for foreigners. The key is understanding how income is treated under US rules. We look at ECI vs FDAP non-resident treatment, as it affects tax rates and paperwork.
It’s important to separate tax exposure from headlines. A US LLC is easy to form. But, the tax outcome depends on where work is done, where customers are, and if there’s a real US presence.
When federal income tax may apply: US trade or business, US employees, US inventory/warehousing, US-sourced FDAP
Federal income tax may apply if the LLC is seen as a US trade or business. This can happen if there are US employees, US facilities used, or operations that seem US-based.
Running a US trade or business through active operations in the United States.
Hiring US employees or using dependent agents who regularly close deals.
Holding US inventory or using US warehousing and fulfilment as part of the sales cycle.
Receiving US-sourced passive income that falls under FDAP, which can bring FDAP withholding 30% unless a treaty rate applies.
For FDAP items like interest, dividends, or royalties, payers often ask for W-8BEN. This document proves non-resident status and supports any reduced withholding rate. Getting this wrong can lead to too much tax withheld or delays in payment.
Why many online-only, no-US-presence models may not have Effectively Connected Income (ECI)
Many online-only models serve US clients without a US presence. Without an office, no US employees, and no US-based operations, income may not be treated as ECI. This is even if the LLC is registered in a US state.
So, ECI vs FDAP non-resident analysis is crucial. Active trading with a US presence might be ECI. Certain passive streams can be FDAP with withholding at source.
Tax residency versus entity formation: forming a US LLC does not automatically make you a US tax resident
Forming a US LLC does not automatically make a founder a US tax resident. Tax residency and filing duties depend on facts like days in the US, where decisions are made, and if business activities are a US trade or business.
Where ECI applies to a non-resident individual, it is commonly reported on Form 1040-NR. Tax is calculated on a net basis under the relevant rules. Cross-border structures involve withholding, source rules, and state questions. We treat each case as fact-specific and best reviewed with qualified tax support.
US LLC compliance filings you cannot ignore (even if you owe no US tax)
Many non-resident founders think “no US tax” means “no paperwork”. But, US LLC compliance can still apply, even with no profit. We plan early to avoid missing deadlines, which can disrupt banking and trading.
Form 5472 with pro forma Form 1120 for foreign-owned single-member LLCs and the $25,000 minimum penalty risk
If you have a Form 5472 foreign-owned LLC, you might need to file Form 5472 with a pro forma 1120. This is required even if you have no income. It’s for reportable transactions with a foreign owner or related party.
The deadline is usually 15 April. You can ask for a six-month extension with Form 7004. Many founders are surprised that these filings are often sent by post or fax, not e-filed.
- Missing the deadline can trigger a $25,000 penalty per Form 5472.
- Further $25,000 penalty amounts may apply if the IRS issues a notice and noncompliance continues.
For remote operators, the IRS accepts digital signatures on certain forms in 2026. This includes the Form 8453, 8878, and 8879 series.
State-level annual obligations: Wyoming annual report (~$60/year minimum); Delaware franchise tax (~$300/year due June 1); New Mexico generally $0 annual report requirement
State rules are different from federal ones. They are easy to miss when you focus on sales. The Wyoming annual report fee is around $60 per year minimum, due on your anniversary month.
Delaware has its own rules. The Delaware franchise tax June 1 deadline is important for budgeting. It’s usually around $300. Sources say Delaware LLCs don’t file an annual report, but the tax must be paid on time.
New Mexico is low maintenance. There’s usually a $0 annual report requirement. But, we still keep track of registered agent renewals and state notices. Missing admin can lead to reinstatement work.
BOI reporting context under the Corporate Transparency Act: verify the current FinCEN position as rules have changed (notably updates announced in 2025)
BOI reporting has changed under the Corporate Transparency Act. We check it before filing. The 2025 update changed expectations, with some US-created entities possibly exempt. Foreign reporting companies may still have obligations and deadlines.
Because the rules can change, we check the current FinCEN position at filing time. We document our decision to keep your compliance record clear and consistent.
Choosing a US state as a non-resident: Wyoming vs Delaware vs New Mexico (and when Florida makes sense)
Choosing a state is not just about looks. It affects your yearly tasks, paperwork, and how you explain your business to others.
When we look at Wyoming vs Delaware vs New Mexico LLC, we focus on your business needs. For many, the best state is one that lets you focus on your work without hassle.
Wyoming
Wyoming is great for online businesses like SaaS, agencies, and e-commerce. It has no state income tax and is known for being easy to manage.
It’s also good for keeping costs down. The annual report is about $60, and it works well with online payment systems like Mercury and Stripe.
Delaware
Delaware is good if you need to impress investors. Its legal system is strong, with the Delaware Court of Chancery handling business disputes well.
But, it’s more expensive. The franchise tax is around $300 a year, due on 1 June. Delaware is also well-known, with over 66% of Fortune 500 companies registered there.
New Mexico
New Mexico is cheap to start with, with a filing fee of about $50 and no annual report needed. It’s good for those watching their costs closely.
But, it might not be as well-recognised as Delaware or Wyoming. This could affect how easily you sell your business.
Florida
Florida is best if you have strong ties there, like local staff or premises. If not, it might add unnecessary complexity.
The annual report fee is $138.75, due by 1 May. If you operate in another state, you might face extra costs and paperwork.
Realistic costs and budgeting: avoiding “$0 LLC” surprises
When setting up a US LLC from the UK, we focus on real costs, not just the initial offer. The cost of a non-resident LLC is rarely zero. This is because of state fees, banking, and compliance. To stay in control, budget early and keep things simple.
Typical first-year cost range for a non-resident US LLC
Most founders can expect to pay between $300 and $900 in the first year. This range depends on the state and the level of support needed.
- State filing fees vary, from $50 in New Mexico to $100–$102 in Wyoming, and $108–$110 in Delaware.
- Formation packages might seem cheap, but they often miss out on essential services.
What “$0” adverts usually leave out
Many “$0” LLC offers hide fees that appear later. A registered agent fee is essential in every state, costing around $49–$150 per year.
Charges for EIN help can also surprise you, if you don’t have an SSN. Form 5472 preparation is another often-overlooked cost. Foreign-owned LLCs may need this form, and missing it can lead to a $25,000 penalty. So, many owners budget for professional filing from the start.
Ongoing annual costs by state
Annual costs vary by state, based on reporting rules and taxes. Wyoming LLCs have a minimum annual cost of around $60, including the registered agent fee.
- New Mexico: usually has no annual report requirement, keeping costs low.
- Wyoming: requires an annual report, with a minimum of $60.
- Delaware: has a franchise tax of about $300 per year, due by 1 June.
We also watch for hidden costs like foreign qualification and sales tax registrations. These can add up, as can the time lost dealing with bank or Stripe issues before getting an EIN.
Common mistakes non-residents make when choosing UK Ltd vs US LLC
When founders look at UK Ltd and US LLC, the paperwork seems simple. But, the real problems are in timing, following rules, and where the business operates. These mistakes are common because they seem small at first but become costly and hard to fix later.
Choosing the “best known” state, not the best fit
Many choose Delaware or Wyoming for their reputation, not the actual work. Delaware might look good, but it can be expensive for small online businesses. Its franchise tax is around $300 a year, which can be a big burden if you’re still testing your idea.
It’s better to pick a state that fits your business plan. Consider where you sell, hire, and how much paperwork you can handle. If you won’t need venture capital, the Delaware name might not be worth it.
Forming first, then discovering the EIN bottleneck
Another common mistake is planning without thinking about the EIN timeline. Without an SSN, getting an EIN can take 10–15 business days by fax or 4–6 weeks by post. This delay can stop you from using Stripe and PayPal, even if your LLC is formed.
Also, applying for a bank account too early can lead to EIN delay banking rejection. We see the EIN confirmation letter as a key step for banking and payments, not something to overlook.
Missing the filing that carries the sharpest penalty
For foreign-owned single-member LLCs, Form 5472 with a pro forma 1120 is often required, even with no US income. The penalty for late Form 5472 can be as high as $25,000. This makes a simple mistake very costly.
Some also think “no tax due” means “no filing due”. But, keeping accurate records and tracking transactions makes filing easier.
Registering in one state, operating in another
Founders might register in Wyoming or Delaware but operate elsewhere, forgetting about foreign qualification. If you have staff, an office, or regular in-state work, you might need to register in another state.
Also, sales tax nexus can be a problem. Having inventory in a US warehouse, a fulfilment arrangement, or in-state employees can mean you must collect and remit sales tax. This is why choosing between UK Ltd and US LLC is not just about formation but also about staying compliant as you grow.
How Start Company Formations can help you decide and set up correctly
Start Company Formations helps you pick between a UK Ltd and a US LLC. We consider where you sell, how you get paid, and what your clients expect. If you need USD invoicing and a US presence, we guide you through the best path.
If your business is mainly in the UK, we make setting up a UK Ltd easy. We keep the costs clear and the process simple.
For non-residents setting up a US LLC, we help choose the right state. We look at Wyoming, Delaware, New Mexico, or Florida, and the costs. We also explain the need for a registered agent and the cost, which is usually $49–$150 a year.
We set clear expectations for filing times, from same-day to 5–15 business days. This helps you plan your launch well.
Most delays happen because of poor planning. Our EIN help focuses on timing and accuracy. We guide you through submitting Form SS-4 and waiting for EIN confirmation before banking and online payment setup.
We also prepare your KYC/AML bundle. This includes the Certificate of Formation, EIN letter, Operating Agreement, and passport. This helps avoid issues with onboarding at Mercury and Relay.
We keep compliance in mind from the start. This includes Form 5472 and the $25,000 minimum penalty risk. We also cover state duties like Wyoming’s ~$60 minimum and Delaware’s ~$300 due 1 June.
New Mexico’s typical $0 annual report position is another factor. We also update you on BOI reporting changes. For wider expansion, we work with business immigration advisers. We support regulated areas like gaming licence work and FX crypto licensing. To discuss your options, call Start Company Formations on 0204 504 1544.
