If you're running a small business in the UK, one of the most important financial figures you need to keep on your radar is the VAT threshold. It’s the magic number that determines whether you need to start charging Value Added Tax (VAT) on your sales.
As of April 2024, that number is £90,000. If your business's total sales cross this amount in any rolling 12-month period, you are legally required to register for VAT with HMRC.
What Is the VAT Threshold?
Think of the VAT threshold as a line in the sand drawn by the government. On one side, you're free from the complexities of VAT. Cross it, and your tax responsibilities change in a big way. The whole point is to give smaller businesses a bit of breathing room, letting them focus on getting established without getting tangled up in VAT admin too early.
The system is all about your taxable turnover, which is a crucial distinction—it's not based on your profit. Your taxable turnover is the total value of everything you sell that isn't VAT-exempt. Every time you make a sale for a standard-rated product or service, you're adding to a running total. Once that total hits £90,000 within any 12-month window, the clock starts ticking on your registration.
A High Threshold to Support Growth
The UK government intentionally keeps the VAT threshold high compared to most other developed countries. In April 2024, it was bumped up from £85,000 to £90,000—the first increase since 2017. This single change is expected to keep around 28,000 micro-businesses from having to register, saving them a significant amount of administrative hassle and cost.
The UK's £90,000 threshold is the highest among all OECD nations (along with Switzerland) and is more than double the average across both the EU and the OECD. This supportive policy means about 3.2 million of the UK’s smallest businesses don't have to deal with the VAT system at all.
This approach makes the UK a particularly friendly place for new and small enterprises to get off the ground.
UK VAT Threshold Key Figures
To help you get a clear picture, here’s a quick summary of the critical figures related to the UK VAT threshold that every small business owner should know.
| Metric | Amount | Significance |
|---|---|---|
| Registration Threshold | £90,000 | The turnover in any rolling 12-month period that triggers mandatory registration. |
| Deregistration Threshold | £88,000 | If your turnover drops below this, you can ask HMRC to cancel your VAT registration. |
| OECD Average Threshold | £34,700 | Shows just how much of an advantage UK businesses have compared to international peers. |
This structure, with a slightly lower deregistration threshold, is designed to stop businesses from bouncing in and out of the VAT system if their turnover hovers around the main limit.

How to Calculate Your Taxable Turnover Correctly
Calculating your turnover for the small business VAT threshold isn't as simple as glancing at your annual sales report. The secret lies in a concept that often catches business owners out: the ‘rolling 12-month’ calculation. Getting into the habit of tracking this figure is the best way to stay on the right side of HMRC and avoid any nasty surprises.
Think of it as a continuous, moving window. At the end of every month, you must look back over the preceding 12 months and tally up your total taxable sales. For instance, at the end of May, your calculation would cover the period from 1st June of last year right up to 31st May of the current year. You repeat this every single month, giving you a constantly updated snapshot of your position.
What to Include in Your Calculation
To get your turnover figure right, you need to be crystal clear on what income actually counts. It’s not always just your main revenue stream.
You must include the value of all goods and services you sold that are subject to VAT. This means adding up:
- Standard-rated items: This covers most of the goods and services you're likely to sell.
- Zero-rated items: This includes things like most food, children’s clothing, and books. Even though you don’t charge your customers VAT on these sales, their value still counts towards your threshold turnover. It's a crucial point that many people miss.
- Sales to other EU countries: The value of goods sold to businesses in other EU member states needs to be included.
- Hiring out goods: If you hire or loan goods to your customers, that income is part of the calculation too.
This flowchart gives a simple overview of the steps to take once you've done your calculation.
As you can see, the whole process starts with an accurate turnover figure, which then points you towards the right action regarding the registration threshold.
What to Exclude from Your Calculation
Just as important is knowing what to leave out of your turnover calculation. Including the wrong income could push you over the threshold unnecessarily.
It’s a common misconception that all business income counts towards the VAT threshold. However, certain sales are deliberately excluded, such as VAT-exempt supplies and the sale of capital assets, which can significantly alter your final turnover figure.
Make sure you exclude the following from your rolling 12-month total:
- VAT-exempt supplies: This is income from specific services like insurance, finance, and certain types of education and healthcare.
- Sales of capital assets: If you sell a company van, a key piece of machinery, or some old office furniture, that one-off sale does not count towards your taxable turnover.
- Disbursements: These are costs you pay on a client's behalf and simply pass on to them without any markup.
The most effective way to stay on top of this is to monitor your rolling total consistently, whether you use accounting software or a simple spreadsheet. It transforms a confusing tax rule into a predictable part of running your business. If you're ever in doubt about what counts, getting some expert advice is a small investment that can prevent very costly mistakes down the line.
Navigating the VAT Cliff Edge
For a growing business, inching closer to the small business VAT threshold can feel less like hitting a milestone and more like tiptoeing towards a sheer drop. This is what many of us in the business world call the "VAT cliff edge." It captures that sudden, jarring change a business goes through the moment its turnover ticks over the registration limit.
One day, you're running your business as usual. The next, you're legally bound to add 20% to your prices or take a massive chunk out of your own profits. It’s not just another form to fill out; it's a fundamental shift in your entire strategy. If you sell to the public (B2C), that sudden 20% price increase can send customers running. If you mostly sell to other businesses (B2B), it might not be a huge deal, since they can usually claim the VAT back.
The Dilemma of Deliberate Growth Stagnation
This cliff edge presents a strange and frustrating problem. Many business owners realise it’s actually more profitable to slam the brakes on growth than to push past the threshold. This isn't just an anecdotal feeling; the data shows it's a widespread behaviour.
Research reveals a significant cluster of businesses reporting turnover just shy of the VAT registration limit. For instance, in the 2021/22 tax year, over 21,700 businesses reported turnover between £84,000 and the £85,000 threshold. In stark contrast, very few reported figures just above it. This strongly suggests that thousands of entrepreneurs are actively capping their income to stay out of the VAT system.
Making the choice to stop growing is a tough pill to swallow. It might mean turning down exciting new projects, dialling back your marketing, or even shutting up shop for a few weeks before your year-end. While this approach avoids the immediate headache of VAT administration and pricing chaos, it carries a heavy long-term price: missed opportunities and stunted potential. Acknowledging this reality is the first step toward making a proactive choice about your business's future.
Weighing Your Strategic Options
So, what do you do? Do you cap your growth and play it safe, or do you take the leap, register for VAT, and embrace the next stage? There's no single right answer here. The best path forward depends entirely on your business model, who your customers are, and what you want in the long run.
Think about it this way:
- Short-Term Relief: Staying under the threshold keeps your prices competitive and your paperwork simple.
- Long-Term Cost: Purposefully holding your business back means giving up on potential revenue, losing market share, and shelving your bigger ambitions.
It's also worth remembering that these kinds of tax complexities aren't unique to the UK.

Understanding the cliff edge gives you the power to make a deliberate, strategic choice for your future, rather than letting a tax rule dictate your success.

When and How You Must Register for VAT
Knowing when to register for VAT isn't just about ticking a box; it’s a critical part of running your business properly and staying on the right side of HMRC. It's not a single moment in time, but a continuous process of monitoring your sales. There are two main triggers that every business owner needs to keep a close eye on.
The Backward-Looking Test
The most common trigger is what’s known as the "backward-looking" test. You’re legally required to register for VAT if your total taxable turnover for the last 12 months has gone over the £90,000 threshold. The key here is that this isn't about your financial year or the calendar year. It’s a rolling 12-month period that you should be checking at the end of every single month.
Think of it like this: at the end of May, you look back at your sales from 1st June of last year to 31st May of this year. If that total is more than £90,000, you've crossed the line. Once that happens, the clock starts ticking. You have 30 days from the end of that month (in this case, by 30th June) to get your registration sorted with HMRC.
The Forward-Looking Test
The second trigger is a bit different—it's about what you know is coming. This "forward-looking" test means you must register if you have good reason to believe your VAT taxable turnover will exceed £90,000 in the next 30 days alone.
This rule is designed to catch situations where a single large contract or a sudden, massive spike in business will push you over the limit all at once. For instance, say you land a huge project on 15th July that's worth £100,000. Even if your turnover was minimal before that, you have to register. The deadline is tight: you have 30 days from the date you realised you'd breach the threshold, not 30 days from when the invoice gets paid.
It's worth remembering that you don't have to wait to be pushed into registering. You can register for VAT voluntarily, even if you’re well under the small business VAT threshold. This can be a really smart move, particularly if you sell to other VAT-registered businesses, as it lets you claim back the VAT on your own costs and purchases.
How to Get Registered
Once you know you need to register, the actual process is pretty straightforward. Most businesses handle it online through the Government Gateway portal. If you get your documents in order first, it can be a quick and painless task.
To get started with your online VAT registration, you'll generally need to have these details handy:
- Your Unique Taxpayer Reference (UTR) number.
- Your business bank account details.
- Information on your business activities and turnover.
- If you're a limited company, your company registration number.
Having this information ready turns what feels like a major compliance headache into a simple administrative step. A little preparation ensures you get registered correctly and on time, letting you get back to what you do best—running your business.
Consequences of Registering for VAT Late
Failing to register for VAT on time is one of the most common—and costly—mistakes a growing business can make. The consequences aren’t just a slap on the wrist. We’re talking about significant financial penalties that can really sting and throw your cash flow into chaos. Getting a handle on these risks is the best way to steer clear of them.
The moment you miss that registration deadline, you’re on HMRC’s radar for penalties. This isn't a simple flat fee; it's a percentage of the total VAT you should have paid while you weren't registered. The longer you put it off, the higher that percentage climbs.
The Double Impact of Penalties and Backdated VAT
The financial hit you'll face comes from two different directions. First, there's the direct penalty for registering late. But the second part is often far more painful: the "backdated VAT." This means you owe HMRC the VAT for the entire period between when you were supposed to register and when you finally did.
This creates a serious headache. Since you weren't registered, you weren't charging your customers any VAT. But HMRC still expects you to pay it. Suddenly, you're stuck between a rock and a hard place with two terrible options:
- You could try going back to all your past customers to ask for the extra VAT. Good luck with that—it's not only awkward but can seriously damage client relationships.
- The more likely scenario is that you'll have to pay the entire backdated VAT bill straight out of your own pocket, wiping out a huge chunk of your profits from that time.
The real crux of the problem with late registration is that you become responsible for tax you never actually collected. For a business running on tight margins, a sudden, unexpected VAT bill covering months of sales can be a devastating financial shock.
Understanding the Penalty Structure
HMRC calculates the penalty as a percentage of the VAT you owe, from your effective registration date right up until they get your application. The rate all depends on how late you are:
- Up to 9 months late: The penalty is 5% of the VAT due.
- Between 9 and 18 months late: This jumps up to 10%.
- Over 18 months late: The penalty maxes out at 15% of the VAT due.
It's worth noting there’s also a minimum penalty of £50. This structure really highlights why keeping a close eye on your turnover against the small business VAT threshold isn't just good admin. It's your single best defence against an expensive and entirely avoidable mistake.
Strategic Planning as You Approach the Threshold
Watching your turnover creep closer to the VAT threshold is a classic good-news-bad-news scenario for any small business owner. On one hand, it's a clear sign of success and growth. On the other, it signals a major financial turning point that requires a solid plan, not a last-minute panic.
Getting this transition right is crucial. How you handle it can seriously impact your cash flow, customer relationships, and profit margins for years to come. The key is to get ahead of it and make some deliberate choices before you're forced to.
To Absorb or to Pass On the Cost
Your first big decision is a strategic one: do you swallow the 20% VAT cost yourself, or do you add it to your prices for customers to pay? There’s no easy answer here, and what works for one business might not work for another.
If your customers are mainly the general public (B2C), slapping a 20% price increase on everything overnight could understandably spook them. But if you absorb the cost entirely, your profit margin takes a direct and painful hit. It's a real balancing act.
- Absorbing the Cost: This keeps your pricing stable and your customers happy, but you need to be brutally honest with yourself. Can your business truly afford to lose 20% of its revenue on every single sale?
- Passing on the Cost: This protects your hard-earned profits, but you risk alienating loyal, price-conscious customers. If you go this route, clear and honest communication is absolutely essential to explain why prices are changing.
Many businesses find a middle ground. A small price increase combined with a slight dip in your own margins can often soften the blow for everyone involved.
Exploring Special VAT Schemes
Thankfully, HMRC realises that standard VAT accounting can be a nightmare for small operations. They've created several special schemes to make life easier, reduce the admin burden, and even help with your cash flow. Taking the time to improve your internal operations by optimizing your business processes can also make managing VAT much simpler.
To help you choose the right path, here’s a look at the main schemes available.
VAT Accounting Scheme Comparison for Small Businesses
| Scheme | Best For | Key Benefit |
|---|---|---|
| Flat Rate Scheme | Businesses with low costs and few purchases (e.g., consultants, freelancers). | You pay a fixed, lower VAT rate and don't need to track VAT on every purchase, simplifying your bookkeeping. |
| Cash Accounting Scheme | Businesses that offer credit and often wait for invoices to be paid. | You only pay VAT to HMRC once your customer has actually paid you, which is a massive help for cash flow. |
| Annual Accounting Scheme | Businesses with a stable, predictable turnover looking to reduce paperwork. | You only submit one VAT return per year instead of four, though you still make regular payments towards your bill. |
Each scheme has its own rules and benefits, so it's well worth investigating which one aligns best with how your business actually operates.
The recent decision to raise the VAT registration threshold from £85,000 to £90,000 was aimed at encouraging small business growth. However, had the threshold kept pace with inflation since 2017, it would be around £103,000 today. This highlights how government policy can influence business strategy, making proactive planning even more crucial. Discover more insights about the complexities of the VAT threshold on ICAEW.com.
Ultimately, approaching the VAT threshold is a significant milestone. With some careful thought about your pricing strategy and a good look at the accounting schemes available, you can turn a potential compliance headache into a smooth, well-managed step on your journey to bigger and better things.
Answering Your Top VAT Threshold Questions
Even when you think you have a handle on the rules, the small business VAT threshold can throw up some tricky real-world questions. Let's walk through some of the most common queries I hear from business owners, so you can feel more confident about your next steps.
Is It Okay to Split My Business to Stay Under the Threshold?
This is a question that comes up a lot, but honestly, it’s a strategy fraught with risk. Intentionally splitting a single business into multiple smaller ones just to keep each part under the VAT threshold is a practice known as "disaggregation." HMRC is wise to this and has specific anti-avoidance rules to stop it.
If HMRC investigates and finds that your businesses are only separated on paper—but are still deeply connected through their finances, operations, and structure—they can treat them as one single business for VAT. The result? You could be hit with a compulsory registration backdated to the point your combined turnover first crossed the line, not to mention some hefty penalties.
What Happens If My Turnover Spikes for Just One Month?
It happens. A single, unexpectedly large contract or a flurry of sales can suddenly push you over the £90,000 limit. If you can prove to HMRC that this was just a temporary blip and your turnover will fall back below the deregistration threshold of £88,000 over the next 12 months, you might be granted an "exception from registration."
You need to be quick, though. This application must be made within the 30-day window you're given to register. You’ll need to back up your claim with solid evidence, like sales forecasts or signed contracts, to show that the spike was a one-off event.
Do I Really Need an Accountant to Handle My VAT?
Legally, no, there’s no rule that says you must hire an accountant for your VAT. But from my experience, it's one of the smartest investments you can make, especially when you're new to the whole process. The VAT rules are notoriously complex, and an innocent mistake can end up being surprisingly expensive.
An accountant does more than just ensure your returns are filed correctly and on time. They bring strategic value to the table. They can advise you on how to price your services, which VAT accounting scheme is best for you, and how to properly claim back VAT on your business expenses. That kind of expert guidance often saves you far more in tax and stress than the cost of their fees, freeing you up to do what you do best: run your business.
