What Counts Toward VATable Turnover?

A guide for sole traders who want to stay on the right side of HMRC

If you’re a sole trader, the words “VAT registration” can feel a bit daunting, especially when you’re not entirely sure what income actually counts toward the threshold. Get it wrong, and you could miss the point at which you’re legally required to register. Get it right, and you can plan ahead with confidence.

So let’s break it all down in plain English.

What Is the VAT Registration Threshold?

As it stands, if your VATable turnover exceeds £90,000 in any rolling 12-month period, you’re required to register for VAT with HMRC. That’s not just your last tax year, it’s any 12-month window, so it’s worth keeping a close eye on your figures throughout the year.

But here’s where it gets a little nuanced: not all of your income necessarily counts toward that figure.

What Does Count Toward VATable Turnover?

VATable turnover includes all sales of goods and services that are subject to VAT,  whether you’re currently charging VAT or not. Here’s what’s typically included:

Standard-Rated Sales (20%)

This is the most common category. If you provide a service or sell a product that would ordinarily attract VAT at the standard rate, it counts. For most sole traders, consultants, tradespeople, freelancers, online sellers, this is the bulk of their income.

Reduced-Rate Sales (5%)

Some goods and services attract a reduced VAT rate of 5%, such as certain energy-saving products or home conversion work. These still count toward your VATable turnover.

Zero-Rated Sales (0%)

Here’s one that catches a lot of people out. Zero-rated sales are still VATable sales,  they just happen to be taxed at 0%. Think books, most food, children’s clothing, or certain transport services. If you sell zero-rated goods, that income still counts toward the £90,000 threshold.

What Does Not Count Toward VATable Turnover?

Just as important as knowing what’s in is knowing what’s out. The following are excluded from your VATable turnover calculation:

• Exempt sales- These are different from zero-rated. Exempt sales include things like financial services, insurance, education, and some healthcare services. Exempt income does not count toward the VAT threshold.

• Outside the scope of VAT - Some income simply falls outside the UK VAT system entirely, such as certain grants, compensation payments, or statutory fees.

• Sale of capital assets-  If you sell a business asset (like a vehicle or equipment you’ve been using), that’s generally not part of your taxable turnover for registration purposes.

• Hobby income (in most cases) - If income isn’t generated as part of a business activity, it’s unlikely to count.

A Quick Way to Think About It

A helpful rule of thumb:

If you would charge VAT on a sale once registered, it almost certainly counts toward the threshold now, even if you’re not registered yet.

Why Does This Matter for Sole Traders?

Because many sole traders don’t realise they’re approaching the threshold until it’s too late. HMRC doesn’t send a warning letter. The responsibility sits with you to monitor your rolling 12-month turnover and register within 30 days of exceeding the threshold.

Fail to register on time, and you could face:

• Back-payment of VAT you should have been charging

• Interest and penalties

• Unwanted attention from HMRC

Practical Tips to Stay on Top of It

1. Review your turnover monthly - Don’t wait until year-end to check where you stand.

2. Use accounting software-  Tools like Xero can track this automatically.

3. Speak to your bookkeeper early- If you’re nudging toward £70–80k, it’s time to have the conversation and plan ahead.

4. Consider voluntary registration- Sometimes registering before you hit the threshold makes sense, particularly if your clients are VAT-registered businesses themselves.

Understanding what counts, and what doesn’t, toward your VATable turnover isn’t just a compliance task. It’s a vital part of running your sole trader business with clarity and confidence.

If you’re unsure where your income sits, or you’re approaching that £90,000 mark and don’t know what to do next, that’s exactly what a bookkeeper is here for.
