Understanding VAT: A Complete Guide for Small Businesses

VAT can seem daunting for small business owners, but understanding the basics is crucial. This comprehensive guide explains everything you need to know about VAT in the UK.

What is VAT?

Value Added Tax (VAT) is a consumption tax added to most goods and services sold in the UK. Currently set at 20% (standard rate), businesses collect it on behalf of HMRC.

How VAT Works

Simple example:

1. You sell services for £1,000 plus VAT (£200)
2. Customer pays you £1,200 total
3. You pay rent of £500 plus VAT (£100)
4. Your landlord receives £600 total
5. You owe HMRC: £200 collected minus £100 paid = £100

This is called “output VAT” (what you charge) minus “input VAT” (what you pay).

Do You Need to Register for VAT?

Mandatory Registration

You must register if:

• Your VAT taxable turnover exceeds £90,000 in any 12-month period
• You expect to exceed £90,000 in the next 30 days alone

Taxable turnover includes:

• Standard-rated sales (20%)
• Reduced-rated sales (5%)
• Zero-rated sales (0%)

But excludes:

• Exempt sales
• Out of scope transactions

Voluntary Registration

You can choose to register even if below £90,000:

Advantages:

• Reclaim VAT on business expenses
• Appear more established
• Necessary for B2B clients who need VAT invoices

Disadvantages:

• Administrative burden
• Quarterly returns (usually)
• May make prices less competitive (if selling to non-VAT registered customers)
• Digital record-keeping requirements

When to Consider Voluntary Registration

Good idea if:

• Most customers are VAT-registered businesses
• High input VAT costs (equipment, stock, rent)
• Planning significant investment
• Competing with VAT-registered businesses

Think twice if:

• Customers are mainly public (B2C)
• Low overhead costs
• Just starting out
• Limited administrative capacity

• Benefit: £650

Important notes:

Annual Accounting Scheme
