VAT Deregistration Process in 6 Steps: A Full UK Guide

VAT deregistration is the process of cancelling your VAT registration with HMRC when your business is no longer required or eligible to be VAT-registered. 

This might apply if you've stopped trading, or your VAT-taxable turnover has fallen below the deregistration threshold.

Getting the process wrong or missing a deadline can lead to penalties and an unexpected VAT bill on stock and assets you still hold. 

Here's what the deregistration process involves, and how to get it right. 

Key points

• There are two different routes into deregistration 🔀
  Voluntary deregistration is available if your turnover is expected to stay below £88,000. Mandatory deregistration applies if you stop trading, sell your business, or no longer meet the conditions of your VAT scheme.
• Your VAT obligations don't end when you apply 📅
  You're still VAT-registered until HMRC confirms your deregistration date, so you'll need to keep charging VAT and filing returns up to that point. Stopping too early is one of the easiest ways to end up with an incorrect final return.
• Stock and assets you still hold can trigger an unexpected VAT bill 📦
  If your business assets are worth more than £1,000 on your deregistration date, HMRC treats them as if you'd sold them, valued at their current market price rather than what you paid. Reviewing your asset register before you apply helps you avoid a surprise bill.
• Deregistering doesn't mean your other tax obligations disappear 🧾
  All your other tax obligations carry on as normal if you're still trading. Remember that deregistration only ends your VAT obligations, not your wider tax responsibilities.
• Accurate records make deregistration far less stressful 💡
  Most VAT deregistration problems come down to not having clear figures ready on time. ANNA keeps your VAT calculations, filing, and records organised throughout the year, so you’re prepared when it's time to deregister.

What does VAT deregistration entail?

Once your VAT deregistration is confirmed, you stop charging VAT on your sales and reclaiming VAT on your purchases, and you no longer need to submit VAT returns.

This is different to closing your business. You can deregister for VAT while continuing to trade, for example if your turnover has dropped and you no longer meet the registration threshold (£90,000).

Similarly, you can stay VAT-registered even after you've stopped actively trading, if you haven't yet told HMRC otherwise.

Getting the timing right matters because VAT obligations end on the date HMRC confirms, not the date you apply to deregister.

The two types of VAT deregistration

You can deregister from VAT in two main ways:

Voluntary deregistration

If your taxable turnover for the next 12 months is expected to fall below the deregistration threshold of £88,000 (2026/27), you can apply to deregister voluntarily. 

This threshold is usually set £2,000 below the VAT registration threshold, but HMRC can change it, so it’s a good idea to double-check the current figures before you apply.

Voluntary deregistration is common among businesses that have scaled down, lost a major client, or changed their business model in a way that reduced turnover. 

You can also stay registered if that benefits your business. For example, if most of your customers are VAT-registered businesses, they can usually reclaim the VAT you charge, so being registered may have little impact on the price they effectively pay. 

Mandatory deregistration

Deregistration is mandatory if:

• You stop trading or making taxable supplies
• You sell your business, or change its legal structure
• You join a VAT group or your business becomes exempt from VAT
• You no longer meet the conditions for the VAT scheme you're registered under

If any of these apply, you need to tell HMRC within 30 days.

Missing this window is one of the most common reasons businesses face penalties during deregistration. Act as soon as your circumstances change rather than waiting until your next return is due. 

🧠 Good to know

If you're not sure which deregistration rules apply to you, check with HMRC or an accountant before you apply. 

The VAT deregistration process in 6 steps

VAT deregistration is handled through HMRC and follows a clear process. 

Here are the six steps to a successful deregistration:

Step 1: Check your eligibility

Before you apply, confirm that your turnover, trading status, or business changes meet HMRC's deregistration criteria. Applying when you don't meet the conditions can delay the process or lead to your application being rejected outright.

If you're deregistering voluntarily, you need to be reasonably confident your turnover will stay below the threshold for the next 12 months. HMRC can ask for evidence to support your forecast, so it helps to have management accounts or sales records that back up your figures.

Step 2: Choose how you'll apply

You can deregister online through your VAT online account, or by post using form VAT7. Most businesses find the online route faster, as HMRC usually processes online applications within a few weeks, while paper applications often take longer.

If you're applying because your business has been sold or has changed legal structure, you may need to provide additional details alongside your application, such as the date of sale or the new structure you're moving to.

Step 3: Submit your deregistration application

You'll need details of your turnover, the reason for deregistering, and the date you want your registration to end. HMRC will confirm your deregistration date once your application is processed, which may not be the date you requested.

Until HMRC confirms your deregistration date, you're still VAT-registered. That means you'll need to keep charging VAT, submitting returns on schedule, and paying anything you owe as normal.

Step 4: Submit your final VAT return

Once HMRC confirms your deregistration date, you'll need to submit a final VAT return covering the period up to that date. This return works differently from your usual ones, since it also needs to account for certain assets you still hold, not just your sales and purchases.

Your final return is usually due one month and seven days after your deregistration date, in line with your usual VAT return deadlines. Missing this deadline can trigger the same late filing penalties that apply to regular VAT returns, even though it's your last one.

Step 5: Account for stock and assets on hand

If you have business assets worth more than £1,000 in total on your deregistration date, such as stock, equipment, or machinery, you'll need to pay VAT on their value as though you'd sold them. This is sometimes called a ‘deemed supply’.

The value used isn't necessarily what you originally paid. HMRC expects you to use the current market value of the assets on your deregistration date. This may be higher or lower than the original purchase price, depending on how the assets have performed.

💡 Did you know?
ANNA's Auto Accountant automatically calculates VAT and tracks what you owe throughout the year, so you're not left guessing what to include or trying to reconstruct your asset values for your final return.

Step 6: Keep your VAT records

Even after you deregister, don't delete or dispose of your VAT records for at least six years. HMRC may ask to see them if they review your VAT history.

This includes VAT invoices, records of purchases and sales, and any adjustments you made on your final return. If you're using accounting software, check whether your access continues after deregistration, since some providers restrict features once your account status changes.

Common mistakes to avoid when deregistering

Some errors come up again and again during the deregistration process, and most are easy to avoid once you know where to look:

• Applying too early or too late: Applying before you're eligible can delay your deregistration, while waiting too long after a mandatory trigger point can lead to penalties. Review your position as soon as your circumstances change, rather than waiting until your next VAT return.
• Forgetting about deemed supplies: Many businesses focus on their final sales and purchases but forget that stock and assets on hand need to be valued and accounted for separately. Go through your asset register before you submit your final return, not after.
• Continuing to charge VAT after deregistering: Once your deregistration date has passed, you'll need to stop charging VAT on invoices immediately. Charging VAT you're no longer registered to collect can cause problems for both you and your customers, particularly if they try to reclaim VAT that shouldn't have been charged.
• Not updating your invoicing and accounting systems: If your invoicing templates or accounting software show your VAT number and automatically add VAT, you'll need to update them as soon as your deregistration is confirmed. Leaving old templates in place is an easy way to accidentally charge VAT incorrectly.
• Assuming deregistration cancels your other tax obligations: Deregistering for VAT doesn't affect your Income Tax, Corporation Tax, or Self Assessment obligations. If you're still trading, you'll continue to report your income and profits as normal, just without VAT in the mix.
