How to Deregister for VAT: When and How

There comes a point for many businesses where VAT registration stops making sense. Perhaps your turnover has dropped below the threshold. Maybe you're closing the business. Or perhaps you registered voluntarily and the benefits no longer outweigh the admin burden. Whatever the reason, VAT deregistration is a process with specific rules, timelines, and obligations that you need to follow carefully.

I'm Penny, and I've guided many businesses through the deregistration process. It's not as simple as flicking a switch, but it's not complicated either -- provided you understand what's involved. Let's walk through everything you need to know.

When Can You Deregister?

There are several circumstances in which you can (or must) deregister for VAT:

Your Turnover Has Fallen Below the Threshold

You can apply to deregister if your taxable turnover has fallen below the deregistration threshold, which is currently £88,000. Note that this is different from the registration threshold of £90,000 -- the gap prevents businesses from constantly registering and deregistering as their turnover fluctuates.

To qualify, you need to satisfy HMRC that your taxable turnover for the next 12 months will be below £88,000. It's not about what happened in the past -- it's about your reasonable expectations for the future.

You've Stopped Making Taxable Supplies

If you've stopped trading or stopped making any taxable supplies (for example, your remaining activities are all exempt), you must cancel your registration. You're required to notify HMRC within 30 days of ceasing to make taxable supplies.

You've Closed the Business

If you're closing down entirely, deregistration is mandatory. Again, you must notify HMRC within 30 days.

Voluntary Deregistration

If you registered voluntarily (because your turnover was below the threshold) and you decide the benefits no longer justify the admin, you can apply to deregister at any time -- provided you've been registered for at least two years. If you registered compulsorily and your turnover has since dropped, the standard deregistration rules apply.

HMRC provides full guidance on when you can deregister at GOV.UK's cancel your registration page.

How to Deregister

The process is straightforward:

Step 1: Apply Online

You can cancel your VAT registration through your HMRC Government Gateway account. Navigate to your VAT account and select the option to cancel your registration. You'll need to provide:

• The date you want your deregistration to take effect
• The reason for deregistering
• Your expected taxable turnover for the next 12 months (if deregistering because turnover has fallen)
• The value of any stock and assets you hold on the deregistration date

Step 2: Wait for Confirmation

HMRC will review your application and confirm your deregistration date. This usually takes a few weeks. You'll receive a confirmation letter with the effective date.

Step 3: File Your Final VAT Return

You must submit a final VAT return covering the period from the start of your current VAT period up to your deregistration date. This return has some special considerations (see below).

Step 4: Stop Charging VAT

From your deregistration date, you must stop charging VAT on your sales. Update your invoices, price lists, and any other documents that show VAT.

The Final VAT Return: Critical Details

Your final VAT return deserves special attention because it includes elements that don't appear on a normal return:

VAT on Stock and Assets

When you deregister, HMRC treats you as if you've supplied all your business stock and assets to yourself. If the total VAT on these items exceeds £1,000, you must account for VAT on them in your final return.

This means going through your inventory and business assets, calculating their current value, and declaring the VAT. The valuation should be based on the market value of the goods at the deregistration date, not what you originally paid for them.

Common items to consider:

• Unsold stock and inventory
• Office furniture and equipment
• Computer equipment
• Vehicles (though cars are usually excluded if VAT wasn't reclaimable on purchase)
• Tools and machinery
• Any other business assets on which you reclaimed input VAT

If the total VAT on all these items is £1,000 or less, you don't need to account for it. This de minimis threshold is a welcome simplification for small businesses with few assets.

Outstanding Invoices

Your final return must include VAT on all invoices you've issued up to the deregistration date, even if customers haven't paid yet (unless you were on the Cash Accounting Scheme, in which case different rules apply).

Similarly, you can reclaim input VAT on purchase invoices received up to the deregistration date, provided you have valid VAT invoices.

Cash Accounting Transition

If you were using the VAT Cash Accounting Scheme, the transition at deregistration requires careful handling. You need to account for VAT on all outstanding invoices (both sales and purchases) that haven't yet been paid, because the cash accounting treatment ceases at deregistration. This can create a lump-sum liability that needs to be planned for.

What Happens After Deregistration?

Pricing Adjustments

Once deregistered, you must stop charging VAT. This means your VAT-inclusive prices should drop -- at least in theory. Whether you actually reduce your prices or keep them the same (effectively increasing your margins) is a commercial decision.

If you've been quoting prices as "£X plus VAT," you'll need to update all your quotes, price lists, website, and invoicing templates. If your prices were quoted as VAT-inclusive, your customers may expect a price reduction.

Record-Keeping Obligations Continue

Even after deregistering, you must keep your VAT records for at least six years. HMRC can audit your previous returns during this period, so don't destroy any invoices, receipts, or accounting records.

You Can't Reclaim Input VAT

Once deregistered, you can't reclaim VAT on business purchases. Any VAT you pay becomes a cost of doing business. This is one of the trade-offs of deregistration, and it's particularly relevant for businesses with high VAT-inclusive costs.

Re-registration

If your turnover subsequently rises above the registration threshold again, you'll need to re-register. If you deregistered voluntarily, you can re-register at any time if your circumstances change.

Should You Actually Deregister?

Just because you can deregister doesn't mean you should. Consider these factors:

Reasons to Deregister

Your turnover is well below the threshold and unlikely to recover. If your taxable turnover is significantly below £88,000 and you don't expect growth, the admin burden of VAT registration may not be justified.

Your customers are mostly consumers. If your clients can't reclaim VAT, deregistering makes your prices more competitive (or increases your margins). This is especially relevant for B2C businesses.

Your input VAT is minimal. If you don't spend much on VAT-inclusive business purchases, the benefit of reclaiming input VAT is small and may not justify the compliance effort.

You're closing the business. Deregistration is mandatory.

Reasons to Stay Registered

You have significant reclaimable expenses. If your business expenses include substantial VAT, staying registered lets you continue reclaiming it, even if your turnover is below the threshold.

Your customers are VAT-registered businesses. B2B customers don't care whether you charge VAT because they reclaim it. Staying registered maintains your professional credibility without costing them anything.

You expect turnover to rise again. If the dip is temporary -- seasonal, cyclical, or due to a one-off factor -- deregistering and then re-registering creates unnecessary disruption.

You're on the Flat Rate Scheme and making a profit. Some FRS users earn a small margin on the VAT they collect. Deregistering eliminates this benefit. Our Flat Rate Scheme guide explains when this applies.

Common Pitfalls

Forgetting About Stock and Assets

The most common mistake in deregistration is failing to account for VAT on stock and assets in the final return. If HMRC discovers you held significant stock at deregistration and didn't account for the VAT, you'll face a retrospective assessment plus penalties.

Before deregistering, make an inventory of everything you hold that you reclaimed VAT on. If the total VAT exceeds £1,000, factor this into your final return planning.

Continuing to Charge VAT After Deregistration

Once your deregistration date passes, you must stop charging VAT immediately. Charging VAT when you're not registered is an offence. Update all your systems, templates, and processes before the deregistration date.

Not Filing the Final Return

Some businesses assume that deregistration means they're done with VAT entirely. But the final return must be filed, and it must be filed on time. Missing it attracts penalties just like any other late return. Check HMRC's guidance on submitting your final VAT return.

Poor Timing

Timing your deregistration strategically can save money. For example, if you have a large input VAT claim coming up (buying new equipment, for instance), process it before deregistering so you can reclaim the VAT. Similarly, if you're holding significant stock, consider reducing it before deregistering to minimise the final return liability.

The Deregistration Process with Accounted

If you're using Accounted, the deregistration process is managed through the platform. I'll help you:

• Calculate the VAT on your stock and assets for the final return
• Ensure all outstanding invoices are accounted for
• Prepare and submit your final MTD-compliant return
• Update your account settings to reflect your deregistered status

You don't need to switch software or change your processes -- everything is handled within the same system you've been using throughout your VAT registration period.

If you're not yet using Accounted but are planning to deregister, signing up before you deregister means I can handle the final return and transition smoothly. Your records will continue to be stored and accessible even after deregistration, meeting HMRC's six-year record-keeping requirement.

After Deregistration: What Changes

The practical changes after deregistration are relatively minor:

• Invoicing: Remove the VAT line, VAT registration number, and any references to VAT from your invoices. Our VAT registration guide covers what VAT-registered invoices need to include, so you'll know what to remove.
• Pricing: Decide whether to adjust your prices. Reducing by the VAT amount keeps prices the same for consumers; maintaining the same price increases your margin.
• Bookkeeping: You still need to keep records, but VAT tracking and return preparation are no longer required. Your bookkeeping becomes simpler.
• Making Tax Digital: MTD for VAT obligations cease with deregistration, though MTD for Income Tax may still apply depending on your circumstances. Our Making Tax Digital complete guide explains the broader MTD landscape.

The Bottom Line

VAT deregistration is a legitimate option when the costs of registration outweigh the benefits. The process itself is straightforward -- apply online, file a final return, stop charging VAT. But the details matter, particularly around stock and assets, timing, and transitional arrangements.

Take time to weigh the pros and cons before applying. Consider your customer base, your expense profile, your growth expectations, and the admin burden. And when you do decide to deregister, plan the transition carefully to avoid the common pitfalls.
