VAT registration is country-specific. Before applying online, identify where your business is established, where it sells or stores goods, and which tax authority controls the registration.
Key Takeaways
- A VAT number is a tax identifier issued after a business registers for Value Added Tax.
- Registration thresholds, deadlines, forms, and online portals depend on the relevant country.
- A VAT number is not the same as a US Employer Identification Number, or EIN.
- Registration may be mandatory because of turnover, expected sales, imports, inventory, or nonresident activity.
- Eligible businesses may register voluntarily to recover VAT on qualifying expenses.
- After registration, the business must charge, report, and account for VAT under local rules.
What VAT Registration and a VAT Number Mean
VAT registration formally places a business within a country's Value Added Tax system. VAT generally applies as goods or services move through the supply chain. A registered business usually charges VAT on taxable sales, tracks VAT paid on qualifying purchases, files returns, and pays the net amount due or claims an available refund.
A VAT number, sometimes called a VAT registration number or VAT tax number, identifies the registered business for VAT purposes. Depending on local rules, you may need to include it on VAT invoices, returns, customs documents, or communications with the tax authority. Registration comes first. The tax authority issues or confirms the number after approving the application.
A VAT number is not interchangeable with a US EIN. The Internal Revenue Service issues an EIN for US federal tax administration, while a foreign tax authority issues a VAT number for its VAT system. If you still need a US identifier, see the requirements for a federal tax ID number. You may need both identifiers when a US company sells in a VAT jurisdiction.
Do not select a registration portal based only on where your company was incorporated. The correct country may depend on where you make taxable supplies, import goods, hold inventory, or sell to consumers. A company can also need more than one VAT registration when its activities reach multiple jurisdictions.
Choose the Correct VAT Registration Jurisdiction First
The first step is to map your actual transactions. Record where the company is legally established, where customers receive goods or services, where inventory is stored, and who acts as importer. Then check the official tax authority for every country that may have taxing rights. Do not combine a threshold from one country with a form or portal from another.
| Business situation | Question to answer | Official route to check |
|---|---|---|
| Established and selling domestically | Has taxable turnover exceeded, or is it expected to exceed, the domestic threshold? | The national tax authority's VAT registration instructions |
| Selling into another country | Do customer location, product type, or nonresident rules require local registration? | The destination country's tax authority |
| Importing or storing goods abroad | Who imports the goods, and does local inventory create an obligation? | Local tax and customs authorities |
| Cross-border EU consumer sales | Can an EU simplification scheme cover the transactions? | The European Commission's VAT One Stop Shop information and the applicable national authority |
| Registering in the United Kingdom | Do UK turnover or non-established business rules apply? | The official GOV.UK VAT registration service |
Your place of incorporation and VAT registration serve different purposes. US business formation or foreign qualification does not automatically produce a foreign VAT number. Likewise, registering an online company does not settle its indirect tax obligations. Review where to register an online business separately from the countries in which VAT registration may be required.
When You Must Register for VAT
Many countries require business VAT registration after taxable turnover crosses a stated threshold. Others apply special or no thresholds to nonresident businesses. Always use the current instructions for the relevant country, especially when checking a VAT registration threshold for 2026 or a later year.
In the UK, GOV.UK states that a business must register when its total taxable turnover for the previous 12 months exceeds £90,000. Registration is also required when the business expects taxable turnover to exceed £90,000 during the next 30 days. Taxable turnover is not necessarily the same as total revenue, because VAT-exempt or out-of-scope supplies receive different treatment.
Other events may also trigger registration. Taking over a VAT-registered business can require you to consider the combined taxable turnover of the acquired business and your existing operation. A business based outside the UK may have to register when it supplies goods or services to the UK, regardless of turnover, subject to the detailed non-established taxable person rules.
A temporary increase may not always lead to permanent registration. For example, the UK allows a business to apply for a registration exception when turnover exceeds the threshold temporarily. A separate exemption from registration may be available in limited zero-rated supply situations, but tax authority approval is required. These are not automatic exclusions.
Missing a mandatory registration date can create liability for VAT on earlier sales, even when you did not charge customers. The authority may also impose interest or penalties under its rules. Check promptly if a rolling turnover calculation, a new contract, or a change in cross-border activity may have triggered registration.
Voluntary, Company, and Self-Employed VAT Registration
A business below its mandatory threshold may be allowed to register voluntarily. Voluntary VAT registration can help when the business incurs substantial VAT on eligible purchases or sells mainly to VAT-registered customers. It also creates ongoing filing, invoicing, pricing, recordkeeping, and payment responsibilities, so the ability to reclaim VAT should not be considered in isolation.
Before registering voluntarily, estimate both input VAT and output VAT. Input VAT is generally the VAT paid on eligible business purchases. Output VAT is the VAT charged on taxable sales. Consider whether your prices can absorb VAT, whether customers can recover it, and whether the administrative cost fits your business. Confirm which pre-registration expenses may qualify for recovery under local rules.
Company VAT registration usually requires the legal entity's incorporation information and details about directors, beneficial owners, or authorized representatives. Self-employed VAT registration generally uses the individual's or sole trader's details, but the person still needs to establish that the activity is a business making taxable supplies. Partnerships, trusts, and other structures may follow different application routes.
VAT registration does not create a company or replace domestic business registration. A sole proprietor can be VAT registered, while an incorporated company can remain below a domestic threshold unless another rule applies. US founders should also handle their domestic registrations independently. For example, registering a business with the IRS addresses different obligations from registering with a foreign VAT authority.
How to Register for VAT Online
Most businesses can register for VAT online through the tax authority for the relevant jurisdiction. Some nonresident businesses, special entities, or applicants seeking an exception may have a different process. Follow these steps without assuming that one country's portal works for another:
- Confirm the jurisdiction. Identify where you make taxable supplies, import goods, store inventory, or maintain an establishment.
- Determine why you are registering. State whether registration is mandatory, voluntary, based on expected turnover, or connected to nonresident activity.
- Create the required online account. Use the official national tax authority portal. Avoid unofficial sites that merely collect application data or charge unnecessary filing fees.
- Enter the business details. Provide the legal name, trading names, structure, registered address, contact information, and incorporation or domestic tax identifiers requested.
- Identify responsible people. Supply details for owners, partners, directors, beneficial owners, agents, or authorized representatives as required.
- Describe taxable activities. Explain what you sell, where customers are located, when trading began, and your actual or expected taxable turnover.
- Add tax and banking information. The portal may request an existing tax number and bank details for payments or refunds.
- Upload supporting documents. Submit readable, current records that match the application.
- Review and submit. Check dates, amounts, entity names, and the requested effective date before certifying the application.
Save the submission confirmation and a copy of every attachment. Do not charge VAT merely because you submitted an application unless the applicable rules require accounting from an earlier effective date. Follow the authority's instructions while approval is pending.
Documents and Information You May Need
The exact VAT online application varies, but preparing a complete file can reduce follow-up questions. Most authorities need enough information to verify the applicant, understand its sales, and determine the correct registration date.
- Legal business name, trading name, structure, and contact details
- Certificate of incorporation, business registration record, or comparable formation document
- Registered office and principal business address
- National tax identification number, if the business has one
- Identification and address evidence for owners, directors, partners, or representatives
- Description of goods or services and the date taxable activity began
- Actual taxable turnover and reasonable projections
- Contracts, invoices, purchase orders, or import records supporting the activity
- Business bank account information when required for payments or refunds
- Details of related businesses, prior VAT registrations, warehouses, or local agents
Names and addresses should match the underlying records. Explain legitimate differences instead of leaving the authority to reconcile them. A US applicant should provide its EIN when requested as its domestic tax identifier, but it should not enter that number as though it were an existing VAT registration number.
Some authorities permit an accountant, tax adviser, or other agent to submit the application. Authorization does not transfer the underlying compliance responsibility from the business. Keep access credentials secure, document who can communicate with the authority, and retain the final registration decision with your corporate and tax records.
VAT Registration for US and Cross-Border Businesses
A business does not need a VAT number merely because it is formed in the United States. The United States has no federal VAT registration system. The relevant question is whether the company's activities create a VAT obligation in a country that imposes VAT.
Potential triggers include importing goods, holding stock in a foreign warehouse, making local supplies, selling certain digital services, or making consumer sales covered by destination-based rules. Marketplaces may collect VAT for some transactions, but that does not automatically resolve every obligation of the underlying seller. Review the marketplace's role, the flow of goods, and invoices issued in the seller's name.
Nonresident businesses may face different thresholds or no domestic threshold. They may also need a local tax representative or additional proof of genuine economic activity. An EU scheme such as the One Stop Shop may simplify reporting for eligible cross-border consumer transactions, but it does not cover every supply or eliminate all possible registrations. If a customer gives you an EU VAT number, the European Commission's VIES service can help validate it for relevant EU cross-border transactions.
If your business sells or imports across several countries, is unsure where registration is required, or needs to correct a late or inaccurate filing, you can post your legal need on UpCounsel's marketplace. An attorney can map your activities to each jurisdiction, coordinate with tax professionals, and review registrations, contracts, and continuing compliance responsibilities. Responses typically arrive within a day.
Keep VAT analysis separate from US entity qualification. Registering a foreign company to conduct business in a US state, discussed in this overview of foreign corporation registration, addresses state corporate authority rather than foreign consumption tax.
What Happens After You Get a VAT Number
Review the registration certificate or online notice as soon as it arrives. Confirm the legal name, VAT number, registered address, effective date, filing frequency, and any approved VAT scheme. Ask the authority to correct errors rather than reproducing incorrect information on invoices or returns.
From the effective date, configure your accounting and sales systems for the correct VAT treatment. Determine which sales are taxable, exempt, zero-rated, or outside the system under local rules. Apply the proper rate, issue compliant invoices, and separate output VAT from business revenue. Retain purchase evidence before claiming input VAT.
You will also need a filing calendar. Return frequency and payment deadlines differ by country and scheme. Some authorities require electronic returns even when the period has no sales. Cross-border businesses may have additional transaction records, currency conversion rules, or reports. Keep supporting invoices, contracts, shipping evidence, customs records, customer location evidence, and communications with tax authorities for the locally required period.
If the effective date predates approval, review transactions from that earlier date. You may need to account for VAT already included in the price, issue corrected invoices where permitted, or contact customers about additional tax. Do not assume approval begins only when the number arrives.
Finally, report material changes through the official process. Changes to ownership, addresses, business activities, banking details, representatives, or trading status can affect the registration. If taxable activity ends or the business becomes eligible to deregister, follow the authority's cancellation procedure rather than simply stopping returns.
Frequently Asked Questions
How Do You Get a VAT Number?
You get a VAT number by applying to the tax authority in the country where your activities require or permit VAT registration. The authority reviews your identity, business activity, turnover, and supporting records before issuing the number. A private invoice template, customer request, or domestic business license cannot create a valid VAT number.
How Do You Register for VAT Online?
You register for VAT online through the applicable country's official tax portal. Select the application for your entity and circumstances, enter the requested ownership and transaction information, attach evidence, and retain the submission receipt. If the portal excludes nonresidents or special entities, follow the alternative process identified by that same tax authority.
What Is a VAT Number?
A VAT number is the unique identifier assigned to a person or business registered within a particular VAT system. Its format depends on the issuing country. A number presented by a customer or supplier should be checked through the verification method recognized by the relevant authority before you rely on it for transaction treatment.
How Do I Get a VAT Number in the USA?
You cannot obtain a US federal VAT number because the United States does not operate a federal VAT system. A US business instead applies to a foreign tax authority when its activities trigger that country's VAT rules. The business may still need an EIN and applicable state tax accounts for separate US obligations.
Do I Need to Be VAT Registered?
You need to be VAT registered when the law of the relevant jurisdiction makes registration mandatory for your turnover or activities. Examine taxable sales, expected contracts, imports, inventory locations, customer locations, and nonresident rules. If none creates a mandatory obligation, the jurisdiction may still allow an eligible business to apply voluntarily.
Are VAT and EIN the Same Thing?
No, VAT and EIN are not the same thing. An EIN identifies a taxpayer for US federal tax administration, while a VAT number identifies a registered person within a VAT jurisdiction. A US company can use its EIN domestically and hold one or more foreign VAT numbers for taxable activities abroad.
What Is VAT Called in the USA?
VAT is not renamed for US federal purposes because the United States does not impose a federal Value Added Tax. State and local governments commonly impose sales and use taxes, but those taxes operate differently from VAT. Registration, collection, filing, and marketplace rules vary by state and should be reviewed separately.
