UK Company Compliance Checklist for International E-commerce Sellers

Running an e-commerce business through a UK limited company can give international founders access to a recognised business structure, UK suppliers and a platform for selling to customers worldwide. But registering a company is only the first step. Staying compliant requires ongoing attention to company filings, tax, VAT, customer protection, product regulations and cross-border trade.

For international e-commerce sellers, the challenge is that UK company compliance and overseas selling compliance are two separate responsibilities. A business can file its Companies House accounts on time and still have VAT obligations in another country. Equally, an online marketplace handling VAT on certain transactions does not automatically take responsibility for every tax or reporting duty the seller has.

This checklist explains the main UK compliance requirements for non-resident founders and international online retailers, including businesses selling through Amazon, eBay, Etsy, Shopify and their own websites.

1. Maintain Your UK Company Registration Details

A UK private limited company must keep its official information accurate and meet its Companies House filing obligations, even if its directors or shareholders live abroad. Use this checklist to review your company's basic details:

• Keep an appropriate registered office address in the UK jurisdiction where the company is registered.
• Maintain an appropriate registered email address for Companies House correspondence.
• Ensure director, shareholder and people with significant control (PSC) details are accurate.
• Update Companies House when reportable changes occur.
• Keep statutory company records and ownership information up to date.
• Make sure directors and relevant PSCs comply with identity-verification requirements.

Companies House identity verification became a legal requirement from 18 November 2025. Directors must provide their Companies House personal code as part of the relevant filing process, while PSCs have separate requirements and deadlines depending on their circumstances. International founders should check the rules for every role they hold.

Does a UK company need a physical office?

Not necessarily a conventional office where staff work every day. However, a registered office must meet the legal requirements for the company's UK jurisdiction and cannot simply be any address chosen for convenience. A professional registered office service may be suitable, but it does not automatically establish that the company has a genuine UK business establishment for VAT or other tax purposes.

Practical tip: Keep your company registration details consistent across your bank, payment processor, marketplace accounts, invoices and accounting records. Differences in names or addresses can trigger verification requests or payment delays.

2. File Your Confirmation Statement on Time

Every UK limited company must file a confirmation statement at least once every 12 months. It confirms that the information held by Companies House is accurate, including relevant details about the company's registered office, officers, share capital, shareholders and PSCs. Your checklist:

• Find the confirmation statement date on the Companies House register.
• Review the company's public information before filing.
• Update changes through the correct filing process.
• Ensure the required identity-verification information is provided.
• Submit the confirmation statement by the deadline.

The confirmation statement is not a substitute for notifying Companies House of every change. Some changes must be reported separately when they happen. The online confirmation statement fee is currently £50. Companies House states that failing to file can lead to a fine of up to £5,000 and the company may be struck off.

For a founder managing a business from another country, calendar reminders and a reliable filing process are particularly useful. Do not assume that an accountant or formation agent will automatically handle every deadline unless you have agreed that responsibility with them.

3. Prepare Annual Accounts and Meet Corporation Tax Obligations

A limited company must prepare annual accounts and deal with its Corporation Tax responsibilities, even if the founder lives overseas or the business has relatively little activity. The main requirements include:

• Maintain complete and accurate accounting records.
• Prepare statutory annual accounts.
• File accounts with Companies House.
• Register for Corporation Tax when required and notify HMRC of the company's trading activity.
• Pay Corporation Tax by the applicable deadline.
• Submit a Company Tax Return when required.

For a typical private limited company, the first accounts are due within 21 months of incorporation. Subsequent annual accounts are generally due nine months after the end of the financial year. Corporation Tax is usually payable nine months and one day after the end of the accounting period, while the Company Tax Return is generally due 12 months after the end of that period. Different rules can apply in particular circumstances.

What if the company has not made any sales?

A company that has not started trading may still have filing obligations. A dormant company generally must file accounts with Companies House, and it must continue meeting applicable confirmation statement requirements. Do not assume that no sales means no compliance responsibilities. Check the company's status and any correspondence from HMRC before deciding what must be submitted.

What records should e-commerce sellers keep?

Maintain records that show how money moves through every sales channel, including:

• Gross sales and refunds.
• Marketplace commissions and payment-processing fees.
• Advertising, shipping and fulfilment costs.
• Inventory purchases and closing stock.
• Import duties and import VAT.
• Currency conversion rates and exchange differences.
• Business expenses and supplier invoices.
• Payments to directors and shareholders.

Marketplace payouts are not the same as gross revenue. If Amazon records £10,000 in sales but deducts fees and refunds before transferring money, the accounting records must still reflect the underlying transactions correctly.

4. Check VAT Registration and Reporting Requirements

VAT is one of the most important areas of compliance for international e-commerce businesses. The correct treatment depends on where the goods are located, where the customer is based, how the sale is made and whether a marketplace is involved.

For a UK-established business, the standard VAT registration threshold is generally £90,000 of taxable turnover under the relevant rolling 12-month test. However, some overseas sellers must register for UK VAT without reaching this threshold, depending on their circumstances and the type of sales they make. Use this checklist:

• Assess whether the company must register for UK VAT.
• Monitor taxable turnover across all sales channels.
• Submit VAT returns when required.
• Pay VAT due by the applicable deadline.
• Keep invoices and supporting VAT records.
• Check whether marketplace VAT rules apply to individual transactions.
• Review VAT treatment when storing stock outside the UK.

Does the marketplace handle VAT for you?

Sometimes, but not universally. Online marketplaces may be responsible for accounting for VAT on certain sales, including particular transactions involving overseas sellers or goods already located in the UK. Other sales remain the seller's responsibility.

For example, an overseas business selling goods directly to UK customers through its own website generally needs to register for UK VAT and account for VAT on taxable sales. Different rules can apply when a marketplace facilitates the sale. Keep marketplace VAT reports and invoices, and reconcile them against your own records. Never assume that a platform's collection of VAT removes every obligation to register, report or retain evidence.

5. Review Tax and VAT Rules in Every Target Market

A UK company selling internationally may also have tax obligations outside the UK. These can arise from the location of its inventory, local sales activity, the type of customer or the destination of the goods.

For example, a company incorporated in the UK might store inventory in Germany through a fulfilment service and sell to customers across the European Union. The UK incorporation does not eliminate the need to assess VAT obligations associated with stock held in Germany or other countries. Your international tax checklist should include:

• Identify every country where the company stores inventory.
• Determine whether local VAT, GST or sales tax registration is required.
• Check whether marketplace rules change who accounts for tax.
• Review obligations when selling to business customers versus consumers.
• Understand local filing and record-keeping requirements.
• Check whether local representatives or fiscal representatives are required.

Do not confuse VAT registration with permanent establishment or corporate tax residence. These are separate legal and tax questions. A company may have a VAT obligation in a country without automatically being tax-resident there, and the exact result depends on the facts and local law.

For businesses selling into the EU, also consider the treatment of imports, marketplace-facilitated sales, and relevant schemes for cross-border transactions. Obtain advice for the specific countries and fulfilment model involved.

6. Obtain the Correct Customs and Import Documentation

If your company imports products into the UK or exports goods to overseas customers, customs compliance must be part of your operating process. Depending on the goods and transaction, you may need an Economic Operators Registration and Identification (EORI) number, customs declarations, commodity codes, accurate customs values and supporting commercial invoices. Check the following before shipping:

• Confirm whether the company needs a UK EORI number.
• Identify the correct commodity codes for products.
• Establish who is responsible for customs declarations.
• Determine the applicable import duty and import VAT.
• Keep supplier invoices, shipping records and customs documentation.
• Agree whether the seller or customer pays import charges.
• Check whether export licences or product-specific restrictions apply.

The correct arrangements depend on where the goods originate, where they are shipped and whether the company is importing or exporting them. A courier or fulfilment provider may handle some customs processes, but the seller should understand which responsibilities remain with the company.

Be clear about delivery terms

International customers can be surprised by customs charges that were not explained at checkout. Decide whether orders will be shipped with duties and taxes paid by the seller or whether the customer will pay charges on arrival. State the relevant delivery and import-cost arrangements clearly before purchase. This can reduce disputes, refused deliveries and refund requests.

7. Comply With Consumer Protection and E-commerce Rules

Company incorporation does not exempt an online retailer from consumer protection rules. Sellers must consider the requirements of each market where they offer products.

For UK consumer sales, online sellers generally need to provide key pre-contract information, including the trader's identity, product details, total price, delivery arrangements and applicable cancellation rights. Your checklist:

• Display accurate product descriptions and prices.
• Provide clear delivery, returns and refund information.
• Give customers the required business contact information.
• Send order confirmations and other required communications.
• Handle complaints, cancellations and refunds in accordance with applicable law.
• Review product safety, labelling and warranty requirements.
• Check local consumer rules before entering new countries.

UK online and distance-selling rules are only part of the picture. Other countries can impose different requirements for cancellation periods, return costs, warranties, product labels and consumer disclosures.

Also check product-specific rules for categories such as cosmetics, toys, electrical equipment, food and supplements. Requirements can include safety assessments, technical documentation, warnings, testing or conformity marking. A marketplace accepting your product listing does not necessarily prove that the product meets every legal requirement in the destination country.

8. Protect Customer Data and Review International Transfers

E-commerce businesses routinely collect customer names, delivery addresses, email addresses, payment-related information and order histories. The company must handle this data lawfully and securely.

Depending on the business and its activities, UK GDPR and the Data Protection Act 2018 may apply. International data transfers can introduce additional requirements. Use this checklist:

• Publish a clear privacy notice.
• Identify the lawful basis for processing personal data.
• Collect only the information needed for legitimate business purposes.
• Keep customer data secure and restrict unnecessary access.
• Review data-processing arrangements with service providers.
• Establish a process for handling data access or deletion requests.
• Check cookie and electronic marketing requirements.
• Assess international transfers of personal information.

If a UK business sends personal information to a separate organisation overseas, or makes it accessible to that organisation, restricted-transfer rules may apply. Depending on the circumstances, the transfer may require an approved transfer mechanism and additional safeguards.

For example, a retailer using overseas customer support staff or a fulfilment provider may need to review how customer records are accessed and protected. The fact that the provider is a recognised commercial service does not automatically resolve the company's data-protection obligations.

9. Keep Business Banking, Payments and Platform Accounts Consistent

International sellers often use several marketplaces, payment processors and currency accounts. Each provider may have its own identity checks, supported-country rules and requirements for company documentation. Review these points regularly:

• Use accurate legal company information in seller accounts.
• Keep director and beneficial-owner details current.
• Maintain supporting incorporation and identity documents.
• Reconcile platform settlements with company bank statements.
• Monitor refunds, chargebacks and withheld payments.
• Review payment-provider terms when the business expands into new countries.
• Keep personal and company transactions separate.

A UK company registration does not guarantee that every payment provider will accept the business. Providers can assess the founder's residence, the company's activities, the countries served and their own risk policies. For non-resident founders, confirm banking and payment-processing eligibility before relying on a particular service as the only way to collect revenue.

10. Build a Compliance Calendar

The easiest way to manage recurring obligations is to assign each task an owner and a deadline.

Directors remain legally responsible for ensuring that the company meets its obligations, even when an accountant or formation agent handles the administration. For a small international seller, a shared calendar and a monthly bookkeeping routine may be sufficient. As the business expands, consider using an accountant familiar with e-commerce, cross-border VAT and the countries in which inventory is held.

Frequently Asked Questions

1. Can a non-UK resident own a UK e-commerce company?

Yes, non-UK residents can generally own UK limited companies, subject to applicable requirements. However, company ownership does not automatically provide UK immigration rights, guarantee a business bank account or determine where the company is tax-resident.

2. Does a UK limited company have to file accounts if it makes no sales?

Generally, yes. A company must meet applicable Companies House filing requirements even when dormant. Its tax obligations depend on its status and circumstances, so confirm whether HMRC requires any further action.

3. Does every international e-commerce seller need UK VAT registration?

No. The requirement depends on the seller's circumstances and transactions. A UK-established business generally assesses the £90,000 taxable-turnover threshold, while certain overseas sellers must register without meeting that threshold. Marketplace and direct-sale rules can differ.

4. Do I need a separate company for Amazon, eBay and Shopify?

Usually not. One UK limited company can operate multiple sales channels if each platform permits the arrangement. Separate companies may make sense when there are distinct ownership, investment or risk-management reasons.

5. Does a UK company need an EORI number?

An EORI number may be required when the company imports or exports goods through customs processes. The exact requirement depends on the country, goods and transaction. Check the relevant customs guidance before shipping.

6. Can a marketplace take responsibility for all my taxes?

No. Marketplaces may account for certain VAT transactions, but sellers can still have registration, reporting, income tax, Corporation Tax, customs and overseas tax responsibilities.

7. What happens if I miss a Companies House deadline?

Late filing can lead to financial penalties and further enforcement. Failure to file a confirmation statement can also put the company's status at risk. Check the relevant filing requirements promptly and take corrective action rather than waiting for a reminder.

8. Do I need to comply with UK GDPR if most of my customers live abroad?

Potentially. The applicable data-protection rules depend on the business's establishment, activities and the people whose data it processes. International data transfers and the laws of customer markets may introduce additional requirements.

Conclusion: Treat Compliance as Part of Your International Growth Strategy

A UK company can provide a useful foundation for international e-commerce, but incorporation is not a one-time compliance exercise. Directors must maintain company records, file accounts and confirmation statements, meet tax obligations and keep official details accurate. International sellers must also look beyond Companies House. VAT, customs, product safety, consumer rights and data protection can all affect whether a business can sell successfully in a particular market.

Use this checklist as a starting point, then tailor it to your products, sales channels, inventory locations and target countries. Establish a reliable filing calendar, reconcile sales across platforms and seek specialist advice where cross-border rules overlap.

For global founders, the strongest compliance system is one that grows alongside the business: clear enough to manage from day one, but robust enough to support new marketplaces, overseas warehouses and international customers without leaving important obligations behind.
