UK VAT Registration 2026
If you sell goods or services in the UK, foreign VAT registration may be required from the first taxable supply. Taxenlight will determine the due date, prepare the application and documentation, and once the number has been assigned, can process your foreign VAT returns.
VAT registration in the UK - key figures and rules
Registration is handled by HM Revenue & Customs (HMRC). For a foreign company, the most important thing is to establish whether it has a registered office or appropriate permanent facilities in the UK, and to indicate the date of the first supply, for which it is responsible.
National threshold
Applies to the taxable turnover of a company with its registered office or appropriate permanent establishment in the UK.
No general threshold
A company not based in the UK may need a number from its first taxable supply.
Deadline for submission
For a company not based in the UK, the deadline relates to delivery or the expectation of delivery.
UK VAT number
Once registered, HMRC issues a nine-digit number used on invoices and records.
From our experience Taxenlight
Most delays don't occur during data entry. They occur when the contract, warehouse, platform, and customs documents all list different entities as either the seller or importer. Before submitting an application, we always first sort out the transaction model and the obligation date.
When does a foreign company need to register for VAT in the UK?
Registration is generally required when a company makes a taxable supply in the UK, and the company is responsible for settling the tax. For a company without a UK registered office, the first such supply, even at a 0% rate, may be relevant.
A company based in the UK
It tests the £90,000 threshold against a 12-month period and a 30-day period. Deliveries with rates of 20%, 5%, and 0% are included in the trading.
A company without a registered office in the UK
It does not automatically benefit from the threshold. If it accounts for the taxable supply itself in the UK, the obligation may arise from the first transaction.
Check the headquarters and actual permanent facilities
A mailing address, virtual office, VAT number, bank account, EORI number, or external warehouse alone do not mean that a company is based or has permanent facilities in the UK. It's the human and technical resources and their actual involvement in the business that count. The lack of a registered office or appropriate facilities does not eliminate the registration requirement—it may mean missing the threshold.
First, confirm who settles the VAT
If all deliveries are correctly accounted for by the UK buyer under the reverse charge mechanism, registration for them may not be necessary. One additional local delivery could change the outcome.
The £90,000 VAT registration threshold and its limitations
The threshold applies to a company with its registered office or a suitable permanent base in the UK. It is assessed through two independent tests. It should not be treated as an annual limit calculated solely at the end of the year.
| Test | What are you analyzing? | Deadline and date of registration |
|---|---|---|
| Historical | Previous 12 monthsAt the end of each month, you add up your taxable turnover from the previous 12 months. This is a rolling period. | Once you exceed your allowance, you notify HMRC by the end of the following month. Registration usually begins on the first day of the following month. |
| Future | Next 30 DaysYou are checking whether deliveries in just one period of 30 consecutive days will exceed £90,000. | The registration date is the day on which there is a reasonable expectation that the threshold will be exceeded. |
| A company without a registered office in the UK | First supplyThe threshold does not generally apply where the business itself accounts for the taxable supply in the UK. | Notification is generally within 30 days of delivery or the expectation of delivery. |
Backtest example
If, as at 31 August, your taxable turnover for the previous 12 months is £92,000, the filing deadline is 30 September and your registration date is generally 1 October. Late filing does not automatically extend the obligation date.
Scenarios that most often lead to registration
This is a registration summary, not a complete description of rates, imports, or platforms. Tax details remain in the UK VAT.
Goods in Great Britain
Selling your own inventory from an operator's warehouse or fulfillment center is usually a local supply. A company without a UK headquarters may need a number from the first sale.
Multi-channel sales
The platform may settle the B2C portion, but the seller may still be liable for import, B2B, direct sales and delivery credited to the platform.
Import and domestic sales
Importation itself does not always create an obligation, but import in one's own name combined with subsequent local sale often leads to registration.
B2C direct sales
For eligible shipments up to £135, the seller may collect VAT at the time of sale. One shipment may be sufficient for registration.
Delivery with installation
If the installation takes place in the UK and the purchaser does not account for tax, the overseas supplier may have a local obligation without a threshold.
Northern Ireland
For relevant trade with the EU, check the identification with the XI prefix. Do not use it for ordinary services or every UK transaction.
How to register your company for VAT in the UK?
Divide the process into six consecutive steps. Don't start with the form until you know the basis and date of registration.
Set up a transaction
Describe the product or service, customer, warehouse, importer, platform and place of taxation.
Check out the headquarters and facilities
Determine where the company is headquartered, has permanent facilities, and has actual human and technical resources.
Set a date
Apply the appropriate test: historical, future or first delivery threshold for a non-UK based company.
Prepare evidence
Collect legal data, documents of authorized persons and evidence of planned or ongoing activities.
Submit an application
Use online registration or – where applicable – VAT1 from HMRC.
Start the VAT process
Once your number has been assigned, check your certificate, invoices, digital records and first billing period.
How long does VAT registration take?
HMRC doesn't provide a single safe-haven deadline for every application. Paper applications typically take longer, and questions about your identity or business model can lengthen the process. You can check the current estimated time in HMRC's weekly updated tool. Don't submit a duplicate just because your number didn't arrive quickly.
Where to submit the application and which form should I use?
Most businesses use online VAT registration. The application can be saved and completed later. VAT1 is a specific route, not a parallel option.
| Form | When might it be needed? | Important note |
|---|---|---|
| Online application | Basic PathMost businesses register with the government's digital service. | You will need login details which you can create when you start the process. |
| VAT1 | Paper registrationIncluding foreign partnership, exception to registration, selected groups and units. | First, contact HMRC. Use only the form they send you. |
| VAT1TR | Tax RepresentativeAppointment of a representative for a company not based in the UK. | The form is signed by the taxpayer and the representative. |
| VAT1A / VAT1B | Northern IrelandSelected distance deliveries or purchases of goods from the EU. | Do not include them in regular registration without proper basis. |
| VAT50-51 / VAT5EXC | Special situationsSelected group registrations or request for an exception when the threshold is temporarily exceeded. | The scope depends on the legal status and the reason for the request. |
Do not collect paper VAT1 from a random source
The current procedure requires you to contact HMRC, explain why you cannot register online, and use the form they provide. See the official VAT registration rules1.
Documents for VAT registration in the UK
The scope depends on the legal form, application channel, and sales model. The list below is a starting point; HMRC may request additional materials appropriate to the risks of your specific business.
Company data and documents
- full legal name and organizational form,
- foreign registration and tax number,
- address of the actual principal place of business,
- contact details and details of authorized persons,
- description of all types of activities and the appropriate code,
- reason and proposed date of registration,
- current and forecasted turnover,
- types of transactions and planned VAT rates,
- bank account details or explanation regarding a foreign account,
- information about related or prior activities in the UK.
Evidence of actual activity
- contracts and orders from customers,
- invoices or pro forma invoices,
- a warehouse or order fulfillment operator agreement,
- confirmation of the platform account and description of sales channels,
- goods purchase documents,
- shipping schedule and delivery terms,
- evidence of import or preparation for import,
- description of the website and sales model,
- calculation of the date of occurrence of the obligation.
Identity with paper VAT1
A foreign person providing a foreign ID instead of a UK National Insurance number may need a copy of a government-issued photo ID and two proofs of address. Address documents should be up-to-date; send copies, not originals.
Consistency is more important than the number of attachments
The contract, sales plan, warehouse, platform, pro forma invoice, and indicated registration date should all describe the same model. Please do not submit random or illegible documents.
Taxenlight advises
Before applying, prepare two short notes. The first describes the flow of goods or the place of supply rule. The second explains why the indicated date is the correct registration date. Assign a specific document to each statement. This set of notes speeds up responses to subsequent HMRC inquiries.
UK VAT number, registration date and pending sales
HMRC issues a nine-digit number. In international notation, the standard number may have the prefix GB. For the actual Northern Ireland-EU trade, the prefix XI is used once HMRC has confirmed the status.
Registration date
The obligation date does not have to be the issue date. It can be earlier, and the first settlement should cover transactions from that date.
While waiting
Don't include a VAT number on your invoice before it's issued. You can include future tax in the price and issue a correct VAT invoice once you receive the number.
Number check
HMRC's VAT number checker confirms the validity of a VAT number and the name and address of the entity. It doesn't search for the number by name alone.
What to check before your first invoice?
Verify the name, address, certificate number, and date; the reverse charge rate or basis; buyer details; currency; XI number rules; platform settings; and invoice consistency with the contract and import. If the price was agreed upon as gross, without the right to add VAT, VAT may reduce your net remuneration.
VAT agent and tax representative
A foreign company can manage its affairs independently, appoint an agent, or—if it chooses this option or HMRC requires it—a tax representative. These roles vary in scope and responsibility.
| Role | What can he do? | Responsibility |
|---|---|---|
| VAT agent | Operation based on authorisationMay communicate with HMRC, handle data and perform activities covered by authorisation. | Appointing an agent does not transfer taxpayer liability. Do not provide your login details to the agent. |
| Tax representative | VAT1TRMaintains records and settles UK VAT on behalf of a non-UK based company. | He or she is jointly and severally liable for VAT debts. This is a broader role than simply serving as an agent. |
A representative is not automatically mandatory for every company
HMRC's materials provide for direct action, through an agent, or through a representative. However, in special circumstances, the office may require security or appropriate representation. See form VAT1TR and the agent authorisation rules.
What to do after VAT registration in the UK?
A VAT number alone doesn't complete the process. Registration, invoicing, and declaration obligations begin from the date of registration. Below is a starting list—details on fields, adjustments, and payments are described in a separate guide.
Starting list after registration
- check the certificate and registration date,
- add the VAT service to your company account,
- set the first declaration period and deadline,
- configure digital records and compatible software,
- update invoices and sales system,
- separate platform, direct, B2B and B2C sales,
- check EORI and the method of settling import VAT,
- establish a payment process and an account for refunds,
- verify the need for the XI prefix.
Deletion also requires analysis
Registration must be cancelled when the company ceases to be eligible. The voluntary deregistration threshold of £88,000 does not apply in the same way for a foreign company that continues to make taxable supplies in the UK.
Check the rules for canceling VAT registrations. Cancellation may also affect EORI.
After the number, go to billing
The declaration field map, deadlines, nil declarations, corrections and payments are described separately so that the guides do not compete for the same intent.
The most common mistakes when registering VAT in the UK
Errors before the application can delay the process, and an incorrect registration date can leave a backlog despite later assignment of a number.
Before the application
- applying the GBP 90,000 threshold to a company without a registered office in the UK,
- no separation of B2B and B2C,
- the assumption that a warehouse or platform always exempts from registration,
- confusing EORI with VAT number.
In the application
- inconsistent start date in contracts and forms,
- agent's address as the principal place of business,
- incomplete description of the activity,
- old or illegible documents,
- incorrect additional form.
After folding
- duplicating an application without checking the status,
- issuing invoices with a number before it is assigned,
- ignoring the previous registration date,
- failure to launch digital records and declarations.
In practice we see
A claim is easier to defend when each claim has a document: date—order, warehouse—logistics agreement, importer—customs declaration, platform sales—channel report. Most often, we correct not a single form, but an entire, inconsistent transaction history.
UK VAT Registration 2026 – Key Takeaways
Registration depends primarily on the place of taxation, the person responsible for VAT, and whether the company has a registered office or appropriate permanent facilities in the UK. A company without a registered office may need a number from the first taxable supply.
First the obligation and the date
Don't start with a form. Establish a model, registered office or permanent base, basis, and correct registration date.
Then consistent documents
Legal data, sales, warehouse, import and platform should form one story.
After the number, start the process
Certificate, invoices, records, import and the first billing period require immediate setup.
FAQ – UK VAT Registration 2026
Answers to questions about the obligation, threshold, VAT1, documents, VAT number, warehouse and tax representative.
Yes, if they make a taxable supply in the UK and are themselves liable for VAT. The UK customer alone does not create the obligation; the place of taxation and the role of the buyer or platform must first be established.
It does not operate as a general threshold for a company without a registered office or adequate permanent establishment in the UK. Such a company may be subject to registration from its first taxable supply.
Most businesses apply online. Form VAT1 is used in certain cases where online registration is not appropriate, and only in the version provided by HMRC.
Typically, you'll need registration and tax information, your actual business address, a model description, turnover, registration date, details of authorized persons and account holders, and proof of intended sales. For the paper VAT1 form, a foreign person may need a photo ID and two proofs of address.
There's no single guaranteed timeframe. Paper applications typically take longer, and additional questions add to the process. For the most up-to-date estimated timeframe, please refer to HMRC's weekly updated tool.
Tax is due from the date of registration, but it cannot be included on a VAT invoice until the number is issued. A price can be agreed accordingly and the correct document issued after receiving the number.
HMRC issues a nine-digit number. In international notation, the standard number may have the prefix GB. For the relevant Northern Ireland-EU trade, the prefix XI is used.
A warehouse alone doesn't mean a company has a registered office or permanent facilities in the UK. However, selling your own goods located in the country often creates a local supply and the obligation to register a foreign company.
Not every foreign company has this obligation. It can operate independently, through an agent, or appoint a representative on the VAT1TR. A representative is jointly and severally liable for VAT debts, while a regular agent generally is not.
Use the official HMRC service. It confirms the number's validity and the entity's name and address. It doesn't allow you to search for a number solely by company name.
Registration must be cancelled when the company ceases to be eligible. The voluntary cancellation threshold of £88,000 is insufficient for a foreign company that continues to make taxable supplies in the UK.
This text is for informational purposes only and does not replace an individual tax assessment. When registering for VAT in the UK, you should verify the company's registered office and permanent facilities, place of taxation, VAT liability, date of obligation, appropriate application channel, documentation, representation, and current HMRC requirements.
