When setting up a business, one of the first big decisions you’ll face is choosing a business structure. In the UK, the two most common options are operating as a sole trader or as a limited company. Each has its pros and cons — and these differences affect not just tax obligations, but also how you register and file for VAT.
Understanding these differences is essential to staying compliant, protecting yourself legally, and making the most of tax opportunities. In this blog, we’ll break down the key differences in VAT registration and filing for sole traders and limited companies, explain their liabilities, outline the forms you need, and help you decide what’s best for your business. Whether you’re running a local shop or figuring out how to start an ecommerce business, these insights will guide you.
What is VAT and Who Needs to Register?
Value Added Tax (VAT) is a consumption tax charged on most goods and services sold in the UK.
Any business with a taxable turnover exceeding £90,000 (as of 2024/2025) must register for VAT with HMRC. You can also voluntarily register if your turnover is below this threshold, which may benefit businesses that reclaim VAT on expenses.
VAT for Sole Traders: Simpler But Personal
A sole trader is the simplest form of business. It is easy to set up, involves minimal paperwork, and profits are taxed as personal income.
VAT Registration and Filing for Sole Traders
- Sole traders register for VAT under their own name (and trading name if used).
- They are personally liable for VAT debts. If you owe HMRC, your personal assets can be at risk.
- You must submit VAT returns (usually quarterly) via HMRC’s online system, using your personal VAT registration number.
- You can reclaim VAT on eligible business expenses.
Example:
Sarah, a freelance graphic designer, has just crossed the VAT threshold. As a sole trader, she registers for VAT and starts charging VAT on her invoices. She is personally responsible for paying collected VAT to HMRC, and she can reclaim VAT on her design software and equipment purchases.
Liability and Protection:
Sole traders do not have limited liability protection. If they fail to pay VAT or other debts, personal assets (like a home or car) can be seized to settle debts.
VAT for Limited Companies: Separate Legal Entity
A limited company is a separate legal entity from its owners (shareholders) and directors.
VAT Registration and Filing for Limited Companies
- VAT registration is done in the name of the company, which gets its own VAT number.
- The company is responsible for VAT debts, not the individual shareholders or directors (except in cases of fraud or misconduct).
- Quarterly VAT returns are filed on behalf of the company, detailing output VAT (collected on sales) and input VAT (paid on purchases).
- VAT payments and reclaim calculations are managed at the company level.
Example:
Tom runs a small online store and recently formed a limited company. His company crosses the VAT threshold, so he registers the business for VAT. The company, not Tom personally, is responsible for paying VAT to HMRC. This gives Tom more legal protection and separates his personal assets from the business liabilities.
Liability and Protection:
Limited companies offer liability protection. Generally, personal assets are protected if the business can’t pay its VAT bill (unless there’s personal wrongdoing).
Forms Required for VAT in the UK
For both sole traders and limited companies, the main forms include:
- VAT1: The application to register for VAT.
- VAT100: The quarterly VAT return form submitted online.
- VAT certificates and VAT registration number: Provided once registration is complete, used on invoices.
For ecommerce VAT, especially for online sellers using platforms like Amazon or Shopify, additional considerations include:
- Correctly accounting for VAT on cross-border sales.
- Using the One Stop Shop (OSS) scheme for EU sales, if applicable.
- Understanding distance selling thresholds in other countries.
Impact on Year-End Accounts
VAT affects your year-end accounts preparation.
- VAT-registered businesses must reconcile VAT transactions throughout the year.
- Input and output VAT must be accurately reflected in your final accounts.
- Errors in VAT filings can cause discrepancies in year-end accounts, potentially triggering HMRC investigations.
When preparing year-end accounts, accountants adjust for any outstanding VAT liabilities or reclaims, ensuring your profit figures are correct.
Choosing a Business Structure: Sole Trader or Limited Company?
The decision between sole trader and limited company impacts far more than VAT.
Advantages of Sole Trader
- Simple to set up and run.
- Fewer administrative burdens.
- You keep all profits (after tax).
However, no legal separation means personal assets are exposed to business debts and VAT liabilities.
Advantages of Limited Company
- Limited liability: personal assets generally protected.
- Potential tax efficiencies, especially on profits over certain thresholds.
- More professional image, which can attract clients and investors.
However, there are more compliance obligations, including statutory year-end accounts preparation, filing corporation tax returns, and maintaining director responsibilities.
Scenario: Ecommerce and VAT
Many entrepreneurs ask how to start an ecommerce business and whether to register as a sole trader or limited company.
Example:
Emma wants to launch an online skincare brand. She expects rapid growth and plans to sell to customers across the UK and EU. By setting up as a limited company, Emma protects her personal assets and can build brand credibility faster.
She registers her company for VAT early to reclaim VAT on startup costs like inventory and website development. She also opts into the OSS scheme to simplify EU VAT reporting.
Emma’s proactive approach — involving early VAT services, proper year-end accounts preparation, and correct business structure — saves her money and future headaches.
Why Early VAT Planning Matters
- Helps avoid unexpected tax bills.
- Lets you reclaim VAT on startup and operating costs.
- Builds trust with suppliers and large customers.
- Supports clean, compliant year-end accounts.
