Do I Need to Register for VAT?

VAT registration is one of those topics that confuses a lot of sole traders and small business owners. When do you have to register? Is it ever worth registering voluntarily? And what happens if you miss the deadline? Here’s a straightforward guide.

When Must You Register for VAT?

You must register for VAT with HMRC if your VAT taxable turnover exceeds £90,000 in any rolling 12-month period. This is the current threshold as of 2026 — it applies to your gross income, not your profit. You can check whether you need to register using HMRC’s VAT registration guidance.

You must also register if you expect your turnover to go over £90,000 in the next 30 days alone — for example, if you’ve just won a large contract.

Once registered, you must charge VAT on your sales, file VAT returns (usually quarterly), and pay any VAT owed to HMRC.

What Counts Towards the VAT Threshold?

Your VAT taxable turnover includes all sales of goods and services that are subject to VAT — including zero-rated supplies. It does not include exempt supplies (such as certain financial services or insurance). If you’re not sure which category your sales fall into, it’s worth taking advice.

What If You Miss the Registration Deadline?

You must register within 30 days of the end of the month in which you exceeded the threshold. Miss this, and HMRC can charge a penalty — and you’ll still owe VAT from the date you should have registered, even if you didn’t collect it from your customers. This is similar to how Self Assessment penalties work — acting promptly is always cheaper.

Should You Register Voluntarily?

Even if your turnover is below £90,000, you can choose to register for VAT voluntarily. There are situations where this makes sense:

• You buy a lot of goods or materials — voluntary registration lets you reclaim VAT on your purchases, which can save money
• Your customers are VAT-registered businesses — they can reclaim the VAT you charge, so it doesn’t put them off
• You want to appear more established — having a VAT number can lend credibility with larger clients

On the other hand, if your customers are mainly individuals (not businesses), charging VAT adds 20% to your prices — which can make you less competitive. It also adds an administrative burden: you’ll need to file regular VAT returns and keep detailed VAT records. Good bookkeeping makes this much more manageable.

VAT and Making Tax Digital

If you’re VAT-registered with a taxable turnover above £90,000, you’re already required to keep digital VAT records and submit your VAT returns through MTD-compatible software. At PBAS, we handle VAT returns for clients using QuickBooks and Xero — both fully MTD for VAT compliant.

VAT Schemes Worth Knowing About

There are three main VAT accounting schemes available to smaller businesses:

• Flat Rate Scheme — for businesses with turnover under £150,000. You pay a fixed percentage of your gross turnover to HMRC, which is simpler than calculating standard VAT.
• Cash Accounting — suits businesses that invoice customers and wait to be paid. You only pay VAT to HMRC once you’ve actually received payment, helping with cash flow.
• Annual Accounting — for businesses that want less admin. You file just one VAT return per year and make advance payments throughout, rather than quarterly returns.

Not Sure Where You Stand?

VAT rules can be more complex than they first appear — especially if you sell a mix of standard-rated, zero-rated, and exempt goods or services. PBAS can assess your situation, advise on the best scheme for your business, handle your VAT registration and returns, and manage your ongoing compliance.
