When is VAT registration in the UK mandatory? When is it optional but beneficial? How does the registration process work and what are the obligations after obtaining a GB VAT number?

This article explains everything a Polish company should know about VAT registration in the United Kingdom.

Issue: Do I need to register for VAT in the UK?

When is registration mandatory?

Polish company must register for VAT in the UK if:

1. Sells goods on DDP terms (Delivered Duty Paid) – The Polish company is responsible for customs clearance and VAT in the UK. 2. Operates a warehouse in the UK (fulfilment centre) – Goods are stored in the UK prior to sale. 3. Sells B2C goods via e-commerce platforms (Amazon UK, eBay UK) – If annual sales exceed £85,000. 4. Provides VAT-liable services in the UK – For example, construction, event, training services physically provided in the UK. 5. Uses Postponed VAT Accounting (PVA) – Requires GB VAT number for import VAT accounting.

When is registration NOT mandatory?

Polish company does not have to register for VAT in the UK if:

1. Sells goods under FCA or DAP terms – The British client is responsible for customs clearance and VAT. 2. Selling goods B2B – The British client has a GB VAT number and accounts for VAT under reverse charge. 3. Provides B2B services – Services are subject to the reverse charge mechanism in the UK.

When is registration optional but beneficial?

Scenario 1: Cashflow Optimisation (PVA)

If a Polish company regularly imports goods to the UK, VAT GB registration allows the use of Postponed VAT Accounting (PVA) – VAT payment deferral at the border.

Benefits: - No need to pay VAT at customs clearance. - VAT settlement directly in the VAT return (net effect = £0 if the company is fully entitled to deduction). - Better cashflow control. More information: Postponed VAT Accounting (PVA) in the UK

Scenario 2: B2C sales via own online store

If a Polish company sells B2C goods (to consumers) in the UK via its own online store, VAT registration in GB may be beneficial if: - Sales exceed £85,000 annually (UK VAT registration threshold). - The company wants to offer VAT-inclusive prices (clearer for customers).

How does the VAT registration process in the UK work?

Step 1: Check if you meet the conditions

HMRC requires that a company registering for VAT in the UK: - Conducted business activity in the UK (sale of goods, provision of services, storage). - Had a UK establishment or tax representative (if the company is not established in the UK).

Important: If the Polish company is not established in the UK, it must appoint tax representative (Fiscal Representative) or VAT agent (VAT Agent).

Step 2: Choose a tax representative or VAT agent

#### Przedstawiciel podatkowy (Fiscal Representative) - Odpowiada solidarnie za zobowiązania VAT polskiej firmy. - Wymaga gwarancji finansowej (bond). - Koszt: £1,000-£3,000/rok.

#### Agent VAT (VAT Agent) - Reprezentuje polską firmę przed HMRC, ale nie odpowiada solidarnie za zobowiązania. - Nie wymaga gwarancji finansowej. - Koszt: £500-£1,500/rok.

Recommendation: For most Polish companies, a VAT agent is sufficient and cheaper.

Step 3: Submit a VAT registration application

Registration is done through the system HMRC (Her Majesty's Revenue and Customs).

Process: 1. Go to the website gov.uk/vat-registration. 2. Select the option "Register for VAT". 3. Log in via Government Gateway (if you have an account) or create a new account. 4. Complete VAT1 form: - Company details (name, address, tax ID). - Type of business. - Estimated UK sales value (annual). - Tax representative/VAT agent details (if applicable). 5. Submit application. 6. HMRC processes application (usually 2-4 weeks). 7. You receive GB VAT number (format: GB123456789).

Step 4: Access the MTD (Making Tax Digital) system

After obtaining a VAT GB number, you must register in the system MTD (Making Tax Digital) – platform for submitting VAT returns online.

Process: 1. Log in to Government Gateway. 2. Select the option "Sign up for Making Tax Digital for VAT"3. Enter the GB VAT number. 4. Choose accounting software compatible with MTD (e.g. Xero, QuickBooks, Sage).
