A Straightforward Guide to VAT for UK Businesses

Ryan Scott • 21 June 2025

What you really need to know about VAT

VAT can feel like one of the trickiest parts of running a business, but understanding the basics goes a long way. Whether you're self-employed, running a growing company, or somewhere in between, staying on top of VAT can protect your cash flow, help avoid penalties, and even boost your credibility with clients.

Here’s a clear, updated overview to help you get to grips with it.



UK VAT data insights — SBX Accountants guide to Value Added Tax for businesses

What Is VAT?

VAT (Value Added Tax) is a tax charged on most goods and services sold in the UK. It’s paid by your customers—but you’re responsible for collecting it and sending it to HMRC.

  • You charge VAT on your sales
  • You pay VAT on most business expenses
  • You report the difference via VAT returns



It’s called “value added” because each business only pays VAT on the value they’ve added in the supply chain.


Do You Need to Register for VAT?

You must register if your taxable turnover exceeds £90,000 in any rolling 12-month period (2025/26 threshold).

Voluntary registration is also possible and may benefit you if:

  • You mostly work with VAT-registered businesses
  • You have significant VATable expenses
  • You want to appear more established



Once registered, VAT becomes part of your regular business admin - so ensure it’s worthwhile.


Charging & Paying VAT

Charging VAT

If registered, you must:

  • Charge VAT on all taxable sales
  • Include your VAT number on invoices
  • Apply the correct VAT rate

VAT rates:

  • 20% Standard Rate – most goods and services
  • 5% Reduced Rate – e.g. energy-saving materials
  • 0% Zero Rate – e.g. food, books, children’s clothing

Important: You can’t charge VAT unless officially registered.

Paying VAT to HMRC

VAT returns are normally filed quarterly, and payment is due one month and 7 days after the period ends.

Payment methods:

  • Direct Debit
  • Bank transfer
  • Debit/credit card
  • Through your HMRC business account


Choosing a VAT Scheme

Different schemes suit different businesses:

Standard VAT Scheme

Charge VAT on sales, reclaim on purchases. Quarterly returns.

Flat Rate Scheme (for turnover under £150,000)

Pay a fixed % of your turnover. Less admin, but limited VAT reclaim.

Cash Accounting Scheme

Pay VAT only when you’re paid by your customers - great for cash flow.

Annual Accounting Scheme (for turnover under £1.35 million)

One return per year, with advance payments throughout the year.

Unsure which scheme is right? We’ll help you choose the most cost-effective option for your business.



Reclaiming VAT on Expenses

You can reclaim VAT on:

  • Tools, equipment, stock
  • Software (e.g. QuickBooks), subscriptions
  • Business travel and mileage (restrictions apply)

You can’t reclaim VAT on:

  • Client entertainment
  • Personal expenses
  • Purchases without valid VAT invoices


Tip: Good recordkeeping is essential. Under Making Tax Digital (MTD), records must be kept digitally. At SBX, we primarily use QuickBooks, but we also support Xero, Sage, and FreeAgent.


Avoiding Common VAT Pitfalls

❌ Failing to track turnover against the threshold

❌ Reclaiming VAT without proper invoices

❌ Claiming on vehicles without checking eligibility

❌ Poor recordkeeping - which may trigger audits


Frequently Asked VAT Questions

Is VAT based on turnover or profit?

Turnover. VAT is not related to profit.

Can I register before hitting £90,000?

Yes, voluntary registration is allowed and can be strategic.

Can I reclaim VAT on costs before registering?

Yes — up to 4 years on goods and 6 months on services, if still in business use.

How often do I file VAT returns?

Usually every 3 months, unless on the Annual Accounting Scheme.

Do I need accounting software?

Yes. Under MTD, VAT-registered businesses must use compatible digital software to maintain records and file returns.
