VAT is one of the most misunderstood areas of tax for small businesses. Many sole traders and limited company directors are either unsure whether they need to register, or delay registration until it becomes a costly problem. This guide walks through who must register, how to do it, and how to handle it once you are registered.

The VAT Registration Threshold

The VAT registration threshold in 2026 is £90,000. This means that if your taxable turnover exceeds £90,000 in any rolling 12-month period, you must register for VAT. "Taxable turnover" means the total value of your VAT-taxable sales — it does not mean profit.

You must also register if you expect your turnover to exceed £90,000 in the next 30 days alone. This "future test" catches businesses that win a large contract and suddenly expect a surge in income.

You can choose to register voluntarily if your turnover is below the threshold — this has advantages in certain circumstances (see below).

VAT Rates in the UK

Not all sales are taxed at the same rate. The three main rates are:

• Standard rate: 20% — applies to most goods and services
• Reduced rate: 5% — applies to items including domestic fuel and power, children's car seats, and some energy-saving materials
• Zero rate: 0% — applies to most food, children's clothing, books, and newspapers. Zero-rated is different from exempt: you can still reclaim VAT on your inputs on zero-rated supplies

Exempt supplies — such as insurance, education, and most financial services — do not attract VAT at all, and businesses making only exempt supplies cannot register.

For comparison, the standard EU VAT rate averages around 21% across member states, while Australia's Goods and Services Tax (GST) is a flat 10%. The US has no federal sales tax, with state taxes varying from 0% to 10%.

How to Register for VAT

Registration is done online through GOV.UK's VAT registration service. You will need:

• Your National Insurance number (for sole traders) or UTR (Unique Taxpayer Reference)
• Business bank account details
• Details of your turnover over the last 12 months
• The nature of your business

Once registered, HMRC will issue a VAT registration number (typically within 10 working days), a VAT certificate, and your effective date of registration. You must charge VAT on taxable supplies from the effective date.

Making Tax Digital for VAT: Already Mandatory

Since April 2022, all VAT-registered businesses must comply with Making Tax Digital for VAT (MTD VAT). This means keeping digital VAT records and submitting VAT returns via MTD-compatible software. You cannot file VAT returns manually through the old HMRC portal.

If you are newly registering, build MTD compatibility into your setup from day one. The HMRC-approved software list includes tools like QuickBooks, Xero, and Sage at around £10–£20 per month.

VAT Schemes for Small Businesses

Three optional schemes can simplify VAT for small businesses:

Flat Rate Scheme: You pay a fixed percentage of your gross turnover to HMRC (the percentage depends on your sector), rather than calculating the difference between VAT charged and VAT reclaimed. This is simpler to administer and can be profitable if your input VAT purchases are low. Available to businesses with taxable turnover under £150,000.

Cash Accounting Scheme: You pay VAT based on when you actually receive payment from customers (not when you invoice), which helps cash flow if customers are slow to pay. Available to businesses with estimated taxable turnover under £1.35 million.

Annual Accounting Scheme: You submit one VAT return per year and make interim payments throughout the year, reducing administration. Available to businesses with estimated taxable turnover under £1.35 million.

Should You Register Voluntarily?

If your turnover is below £90,000, you can still register voluntarily. This makes sense if:

• Your customers are businesses that can reclaim VAT (so adding 20% to your prices does not disadvantage you competitively)
• You have significant VAT-able business costs and want to reclaim input VAT
• You want to appear more established to larger corporate clients

It does not make sense if most of your customers are consumers who cannot reclaim VAT — you would be adding 20% to your prices unnecessarily.

Step-by-Step Checklist: VAT Registration

• Monitor your rolling 12-month taxable turnover against the £90,000 threshold
• Decide whether voluntary registration makes sense for your customer base
• Gather: NI number or UTR, bank details, 12-month turnover figures
• Register online at gov.uk/register-for-vat
• Set up MTD-compatible accounting software before your first return is due
• Assess whether a VAT scheme (Flat Rate, Cash Accounting, Annual Accounting) suits your situation
• Update your invoices to include your VAT number and show VAT separately
