UK Ltd or US LLC: choosing your company, tax treatment and banking
Compare UK Ltd and US LLC setup, 2026 fees, Corporation Tax, banking and annual work. Exentax reviews your activity to help you choose the right structure.
A UK Ltd can be owned and directed by a non-resident. Choosing one is a business decision, not simply buying a British company number. The useful comparison with a US LLC starts with your customers, where you work, how you collect money and what the company will need to do next.
If you are considering a UK Ltd because incorporation looks inexpensive, look one step further. The registration fee does not include banking, accounts, tax work or advice on your own position. A structure earns its place when those parts fit together. This guide helps you compare them before committing.
What you are forming with a UK Ltd
A private company limited by shares has shareholders, directors and its own legal identity. Shares establish ownership; directors manage the business. One person can hold both roles. The share capital you choose is different from the registration fee and from the money the business needs to operate.
The UK is a practical option where a British operation, contract or investor gives you a specific reason to use it. For an international business without that requirement, an LLC deserves a full comparison: flexible ownership arrangements, a US contracting entity and access to an operating setup designed around international payments.
Neither company's name tells you how much tax its owner will pay. Legal form, company taxation and the owner's position are separate decisions. Our LLC, C-Corp and S-Corp comparison explains that distinction for US structures.
Incorporating as a non-resident: prepare the right information
Directors do not have to live in the UK. The company does need an appropriate registered office in its UK jurisdiction of registration. A commercial address service can fulfil that role when it meets the rules; it is not evidence that your work takes place there.
Before applying, settle the company name, directors, shareholders, share allocation, articles and activity code. Identify the people with significant control, or PSCs. For a business with partners, discuss decision-making and a future exit as carefully as the initial percentages.
Identity verification is part of preparation
Companies House introduced mandatory identity verification from 18 November 2025, with transitional deadlines for existing roles. New incorporations need to account for the current director and PSC process. Verification can use GOV.UK One Login or an authorised provider, according to the available route.
Follow the official identity-verification guidance for the person concerned. Keep personal codes secure. Completing this step is not the same as a bank's customer verification, so prepare the banking application separately.
What a UK Ltd costs in 2026
Since 1 February 2026, the digital incorporation fee is GBP 100 and the digital confirmation statement fee is GBP 50. These are Companies House charges, not the total cost of running the company. Different filing methods have different fees.
| Budget item | What to compare |
|---|---|
| Incorporation | GBP 100 official digital fee, plus any agreed professional work |
| Confirmation statement | GBP 50 official digital fee within the relevant payment period |
| Address and correspondence | Service scope, mail handling and renewal terms |
| Accounts and tax work | Activity, transaction volume, VAT, payroll and complexity |
The Companies House fee announcement confirms the effective date. A confirmation statement checks company information; it does not replace accounts or a tax return.
Ask for a quote that separates one-off setup from recurring work. Establish whether bookkeeping, annual accounts, CT600, VAT returns and payroll are included or priced separately. There is no useful universal annual total without that scope. Compare an LLC over the same period using our formation and annual-cost guide, rather than comparing a bare registration with a managed service.
Corporation Tax: company profit is not shareholder cash
A UK-resident company generally falls within Corporation Tax on its worldwide profits. Shareholder residence alone does not determine company residence; incorporation, management and applicable treaty rules form part of that analysis.
The main Corporation Tax rate is 25%, with a 19% small-profits rate for eligible companies and marginal relief where available. The usual GBP 50,000 and GBP 250,000 thresholds are not universal allowances for every company. Profit thresholds are adjusted for associated companies and short accounting periods. Investment holding companies also require specific eligibility analysis.
Use the HMRC rates guidance for the accounting period. Do not calculate company tax from turnover or assume that all profit is taxed at the lowest rate. A reliable comparison starts with deductible costs and taxable profit.
Retaining or reinvesting the money
Leaving profits in a Ltd does not itself remove Corporation Tax. Reinvestment can finance growth, but spending, deductibility and capital allowances are different questions. Salary, dividends, loans and repayment of contributed funds also need to be distinguished.
An LLC's federal classification follows a different framework. A default single-member LLC is generally disregarded for income tax; a domestic multi-member LLC generally defaults to partnership treatment. Foreign ownership is not a separate tax election. The owner's residence and the activity must be considered alongside US rules, particularly where another country classifies the entity differently.
For UK-resident owners, HMRC's foreign-entity classification guidance is relevant. The conclusion should follow the particular structure, not an automatic “LLC means zero tax” or “LLC never works in the UK”.
VAT follows the transaction, not the company label
GBP 90,000 is the general UK VAT registration threshold for taxable turnover, not a blanket exemption for every non-resident business. Establishment, place of supply and reverse-charge rules matter. A business without UK establishment can have different registration requirements.
Describe what is sold, where goods move or services are supplied, and whether the customer is a business or consumer. Those facts are more useful than “I sell online”. The VAT registration guidance provides the starting point. A British company number does not, by itself, settle VAT treatment for European customers.
Build the banking arrangement around the business
First list the currencies you receive, the payment methods customers need and the currencies you spend. Then assess account eligibility for the company, directors, owners and actual operating location. Opening a company and being accepted by a financial provider are separate processes.
A GBP collection account may serve British customers, while other accounts handle EUR receipts, USD payments or reserves. An LLC can also use several compatible providers. There is no reason to force every function into one account or assume that a provider belongs exclusively to one jurisdiction's companies.
Ask about account ownership, local details, conversion costs, transfer routes and processor payouts. Use your real operating address and consistent company information. Exentax helps design that combination around the intended activity; the address and banking-evidence guide explains the different address roles.
Public information: make deliberate address choices
Companies House publishes company information and certain director and PSC details. It does not publish every personal detail: residential addresses and full dates of birth are generally protected from public display when supplied in their proper fields.
A home address used as a registered office or public service address is a different matter. Review those choices before filing. The official public-register guidance distinguishes the fields. Privacy planning means understanding what is public and using appropriate addresses, not leaving the bank without accurate ownership information.
Keep three annual tasks distinct
A confirmation statement, annual accounts and a Company Tax Return serve different purposes. Put each actual deadline in your calendar from the company's record, rather than reusing the formation anniversary for everything.
For ordinary private-company filings, annual accounts are generally due nine months after year-end; first accounts normally have a different deadline. Corporation Tax payment and the return also have different dates. The official filing calendar explains the standard periods and first-year distinction.
Before appointing an adviser, agree who prepares the records, who reviews the return and who submits each filing. A change of accountant should include previous submissions, balances and access handover. This is practical continuity, whether you retain the Ltd or explore an LLC for a separate operation.
Choose from a real operating plan
Illustrative situation: a consultant establishing a British team. Local contracts, staff and management create clear reasons to examine a UK Ltd. The review should include payroll, VAT and the owner's circumstances.
Illustrative situation: an international agency collecting in several currencies. Without a requirement for a British entity, a US LLC may provide an effective contracting and banking structure. Compare ownership, actual working locations and the complete annual service, not a headline tax rate.
These are examples, not client results. If a Ltd already holds contracts or assets, forming an LLC does not move them automatically. Plan any new activity or transfer with its own legal and tax treatment.
Questions before choosing a UK Ltd
Can I form a UK Ltd without living in the UK?
Yes. Prepare the registered office, ownership and identity requirements. Banking and your personal tax position need their own review.
Is GBP 100 the whole setup cost?
No. It is the digital registration fee. Address services, professional advice and ongoing work are separate budget items.
Does retaining profit avoid Corporation Tax?
No. Company profit is assessed under the applicable rules regardless of whether a dividend is paid. Reinvestment should be analysed by the type of expenditure.
Does a US LLC work only for American customers?
No. An LLC can support international activity, compatible banking and payment methods. Its structure should reflect the owners and the business actually carried on.
Can Exentax review a Ltd before I choose an LLC?
We can assess how a proposed US structure fits your activity and coordinate the relevant advice. The scope should address existing contracts, banking and ongoing responsibilities before implementation.
Make the structure serve your next stage
Bring your current company details, countries of operation, customer types, payment flows and next objective. Exentax uses those facts to recommend and organise the LLC structure, documentation, banking and follow-up that suit your case.
You should leave the review knowing what to keep, what to establish and who will handle the agreed work. That is more valuable than another company certificate without a clear purpose.
