VAT Accounting Explained: A Simple Guide for Small Businesses

Do Small Businesses Need to Register for VAT?

VAT registration depends on your turnover and the country’s tax regulations. In many cases, small businesses are required to register for VAT if their taxable turnover exceeds a specific threshold. For example, in the UK, the VAT registration threshold is £90,000 (as of 2025).

You must register for VAT if:

• Your annual taxable turnover exceeds the threshold.
• You expect to exceed the threshold in the next 30 days.
• You buy services from abroad that require VAT reporting.

Voluntary registration: Even if your turnover is below the threshold, you may choose to register voluntarily. This can make your business appear more established and allow you to reclaim VAT on expenses.

How Does VAT Accounting Work?

VAT accounting revolves around two key elements:

1. Output VAT – The VAT you charge customers on sales.
2. Input VAT – The VAT you pay on business-related purchases.

When filing your VAT return:

• If Output VAT > Input VAT, you pay the difference to the tax authority.
• If Input VAT > Output VAT, you claim a refund.

Example:

• Sales (with VAT): £20,000 (Output VAT = £4,000)
• Purchases (with VAT): £10,000 (Input VAT = £2,000)
• VAT due = £4,000 - £2,000 = £2,000

This ensures you only pay VAT on the value you have added to goods or services.

Different VAT Schemes for Small Businesses

To simplify VAT accounting, many countries offer different schemes tailored to small businesses:

1. Standard VAT Accounting

• Record VAT on every sale and purchase.
• Submit VAT returns quarterly (or as required).

2. Flat Rate Scheme (FRS)

• Pay a fixed percentage of your turnover as VAT.
• Designed to simplify accounting for small businesses.
• You can’t reclaim Input VAT (except on large capital purchases).

3. Cash Accounting Scheme

• Pay VAT only when customers pay you.
• Reclaim VAT only when you pay suppliers.
• Ideal for businesses with late-paying clients.

4. Annual Accounting Scheme

• File just one VAT return per year.
• Make advance VAT payments throughout the year.
• Helps businesses with predictable cash flow.

Choosing the right scheme is essential, and this is where expert accountancy services can help small businesses make the best decision.

VAT Records You Must Keep

Proper recordkeeping is a legal requirement. As a small business, you should maintain:

• Sales invoices (showing VAT charged).
• Purchase invoices (showing VAT paid).
• VAT account (a summary of Output and Input VAT).
• Copies of submitted VAT returns.

With the introduction of Making Tax Digital (MTD) in many regions, businesses are now required to keep digital VAT records using accounting software.

Common VAT Mistakes Small Businesses Make

Many small businesses make avoidable mistakes when handling VAT:

1. Late Registration – Waiting too long to register can result in backdated VAT payments and penalties.
2. Incorrect Invoicing – Forgetting to add VAT or applying the wrong rate.
3. Claiming VAT on Non-Business Expenses – Such as personal costs disguised as business purchases.
4. Missing Deadlines – Late VAT return submissions often lead to fines.
5. Poor Recordkeeping – Inaccurate or incomplete records make compliance difficult.

Using professional accountancy services significantly reduces the risk of these mistakes.

How VAT Affects Your Cash Flow

VAT can impact small business cash flow in several ways:

• Positive Impact: If Input VAT exceeds Output VAT, you get a refund.
• Negative Impact: You may have to pay VAT before customers settle invoices.
• Cash Flow Strain: Businesses with seasonal sales often find it challenging to meet VAT payment deadlines.

This is why many small businesses opt for schemes like cash accounting or seek guidance from accountancy services to balance VAT obligations with cash flow needs.
