What Happens If My Turnover Drops Below the VAT Threshold

This is a situation I see more often than people expect. A business grows, registers for VAT because it has to, and then trading conditions change. Work slows down, clients leave, prices are adjusted, or the business deliberately scales back. Suddenly turnover is well below the VAT threshold and the obvious question arises. What happens now?

In this article, I am going to explain exactly what happens if your turnover drops below the VAT threshold, whether you have to stay VAT registered, when you can deregister, and the practical pros and cons of doing so. I will also cover the areas that tend to catch people out, such as asset VAT, timing, and HMRC scrutiny.

Everything here reflects real UK practice and how the rules are applied by HMRC and set out on GOV.UK, but explained in clear practical language.

The VAT Threshold in Context

The VAT registration threshold in the UK is £85,000 of taxable turnover.

This figure applies to compulsory registration and is measured on a rolling 12-month basis. It includes standard rated, reduced rate, and zero rated supplies. It does not include VAT exempt income.

Once you are registered for VAT, simply falling below £85,000 does not automatically remove you from the VAT system.

That is the first and most important point to understand.

You Are Not Automatically Deregistered

If your turnover drops below the VAT threshold, nothing happens automatically.

You remain VAT registered until one of two things occurs:

You apply to deregister and HMRC agrees

You stop trading or otherwise become ineligible to remain registered

Many business owners assume that dropping below the threshold means VAT registration ends on its own. It does not.

You must actively decide whether to remain registered or apply to deregister.

The VAT Deregistration Threshold

There is a separate threshold for VAT deregistration.

You can apply to deregister for VAT if your taxable turnover is expected to be below £83,000 in the next 12 months.

This is slightly lower than the registration threshold to prevent businesses constantly moving in and out of VAT.

The key word here is expected. HMRC is interested in your future turnover, not just what has already happened.

When You Can Apply to Deregister

You can apply to deregister if:

Your turnover has dropped below £83,000

You expect it to stay below that level

The reduction is not temporary

Temporary dips do not usually justify deregistration. HMRC will look at whether the fall in turnover is structural or short term.

Examples where deregistration is often accepted include:

Reducing working hours permanently

Losing a major contract with no replacement planned

Changing business model

Scaling back toward retirement

Closing a product or service line

Examples where HMRC may refuse include:

Seasonal fluctuations

One-off delays in invoicing

Short gaps between contracts

You Can Choose to Stay VAT Registered

Even if your turnover drops well below the VAT threshold, you are allowed to remain VAT registered.

This is entirely optional and in some cases it is the better decision.

Businesses often choose to stay VAT registered because:

Their customers are VAT registered

Deregistration would complicate pricing

They want to reclaim VAT on ongoing costs

They expect turnover to rise again

They import goods and benefit from postponed VAT accounting

There is no requirement to deregister just because turnover has dropped.

The Advantages of Staying VAT Registered

For some businesses, remaining VAT registered despite lower turnover makes commercial sense.

VAT Neutral Customers

If most or all of your customers are VAT registered, VAT is usually neutral.

You charge VAT, they reclaim it, and your pricing position remains unchanged.

In these cases, deregistering often creates more disruption than benefit.

Ongoing VAT Recovery

If you incur regular VAT on costs such as:

Professional fees

Software subscriptions

Equipment

Rent

Imports

Remaining VAT registered allows you to continue reclaiming that VAT.

Deregistering would turn VAT on costs into a real expense.

Avoiding Re-Registration Later

If you expect turnover to rise again, staying registered avoids:

Re-registering

Adjusting prices twice

Updating systems and invoices

Explaining VAT changes to customers

This can be particularly relevant for businesses with fluctuating income.

The Disadvantages of Staying VAT Registered

Remaining VAT registered is not always the right choice.

Higher Prices for Non-VAT Customers

If your customers are members of the public or non-VAT registered businesses, VAT makes you more expensive.

Remaining registered means:

Prices must include VAT

Or margins must absorb VAT

If turnover has dropped because demand is sensitive to price, VAT may be part of the problem.

Ongoing Administration

VAT registration brings ongoing obligations, regardless of turnover.

You must continue to:

Submit VAT returns

Keep digital records

Comply with Making Tax Digital

Pay VAT on time

For smaller or slower businesses, this admin can feel disproportionate.

Cash Flow Considerations

VAT affects cash flow even at lower turnover.

You may still:

Collect VAT from customers

Owe it to HMRC before being paid

Need to manage payment timing carefully

This can be stressful during quieter periods.

Applying to Deregister for VAT

If you decide that deregistration is the right move, you must apply to HMRC.

Deregistration is not automatic and not guaranteed.

How to Apply

You apply online through your HMRC VAT account.

You will need to provide:

Your VAT registration number

The reason for deregistering

The date you want deregistration to take effect

Your expected taxable turnover

HMRC will review the application and confirm whether deregistration is approved.

You must continue charging VAT until HMRC confirms the deregistration date.

Choosing the Deregistration Date

The deregistration date matters more than many people realise.

For voluntary deregistration, the date is usually:

The date you apply

Or a recent past date agreed with HMRC

You cannot choose a future date.

Once deregistered, you must stop charging VAT from that date onwards.

The Final VAT Return

When you deregister, you must submit a final VAT return.

This return covers:

The period up to the deregistration date

All sales and purchases

Any VAT due on stock and assets

The final VAT return is where many surprises occur.

VAT on Stock and Assets When You Deregister

This is one of the most important points to understand.

When you deregister, HMRC treats certain items as if you have sold them to yourself.

You may need to account for VAT on:

Stock on hand

Equipment

Tools

Fixed assets

This only applies where you originally reclaimed VAT on those items.

The £1,000 VAT Rule

There is an important relief.

If the total VAT due on stock and assets is £1,000 or less, you do not need to account for it.

If it exceeds £1,000, VAT is due on the full amount.

This calculation is based on the current market value, not the original purchase price.

Deregistration and Pricing

Once deregistered, you must update your pricing.

This means:

Removing VAT from prices

Updating invoices

Updating website wording

Ensuring prices are no longer described as VAT inclusive

Failing to do this can cause confusion and compliance issues.

What If Turnover Drops Temporarily?

This is where judgement is required.

If turnover has dipped temporarily but is likely to recover, deregistering is often a mistake.

I regularly see businesses deregister during a quiet period, only to:

Grow again

Be forced to re-register

Face VAT on asset re-registration

Rework pricing again

HMRC will also look closely at deregistration requests that appear opportunistic.

What If Turnover Drops Because the Business Is Changing?

If turnover drops because of a deliberate change, deregistration is often appropriate.

Examples include:

Moving from full-time to part-time

Narrowing service offerings

Shifting to exempt activities

Preparing to wind down

In these cases, VAT may no longer serve a purpose.

What If You Stop Trading Entirely?

If you stop trading, VAT deregistration becomes compulsory.

You should apply to deregister as soon as you know trading has ceased.

Delaying deregistration simply creates unnecessary VAT returns and increases the risk of missed deadlines.

HMRC Scrutiny Around Deregistration

HMRC does not object to legitimate deregistration, but they do scrutinise it.

They may look at:

Previous turnover patterns

Industry norms

Linked businesses

Artificial separation

Timing of deregistration

If HMRC believes turnover will exceed the threshold again, they can refuse deregistration.

Artificial Separation Risks

Some businesses attempt to reduce turnover by splitting activities.

HMRC is very alert to this.

If two businesses are:

Under common control

Financially linked

Operationally linked

HMRC may treat them as one for VAT purposes and force continued registration.

Re-Registering for VAT Later

If you deregister and later exceed the VAT threshold again, you must re-register.

There is no penalty for deregistering and re-registering, provided both decisions were correct at the time.

However, repeated movement in and out of VAT can attract HMRC attention.

Record Keeping After Deregistration

You must keep VAT records for at least six years after deregistration.

This includes:

VAT returns

Invoices

Asset records

Stock valuations

Deregistration correspondence

HMRC can still review past VAT periods.

Common Mistakes I See When Turnover Drops

Some of the most frequent issues include:

Assuming deregistration is automatic

Deregistering too quickly after a short dip

Forgetting VAT on assets

Stopping VAT before HMRC approval

Failing to update pricing

Poor documentation

Most of these mistakes are avoidable with a bit of planning.

How I Advise Clients to Decide

When turnover drops below the VAT threshold, I usually advise stepping back and asking:

Is the drop temporary or permanent?

Who are my customers and can they reclaim VAT?

How much VAT do I reclaim on costs?

What VAT would be due on assets if I deregister?

Do I expect turnover to rise again?

The answer is rarely just about the threshold.

Practical Summary

In practical terms:

Dropping below the VAT threshold does not remove VAT registration automatically

You can apply to deregister if expected turnover is below £83,000

You can choose to remain VAT registered

Deregistration can trigger VAT on stock and assets

Pricing and admin implications matter

HMRC will look at intention and patterns

Final Thoughts

When turnover drops below the VAT threshold, you are not facing a rule change, you are facing a decision.

VAT registration should support your business, not hinder it. In some cases, staying registered is the simplest and safest option. In others, deregistering reduces cost and complexity. The key is understanding the consequences before acting.

My advice is always to treat VAT deregistration helpfully but cautiously. A short-term drop in turnover does not always justify a long-term change in VAT status. As with most VAT decisions, the right answer depends on context, not just numbers.
