Should I Register for VAT If I Am Below the Threshold? Pros and Cons

You can choose to register for VAT even if your taxable turnover is below the VAT registration threshold. This is called voluntary VAT registration.

At the time of writing, GOV.UK states that a business must register for VAT if taxable turnover for the last 12 months goes over £90,000, or if taxable turnover is expected to go over £90,000 in the next 30 days. GOV.UK also confirms that businesses can choose to register for VAT below the £90,000 threshold. For the official rules, see GOV.UK’s Register for VAT guidance.

Voluntary VAT registration can be useful, but it is not automatically the right move.

It may help if your customers are VAT-registered businesses, you have significant VATable costs, or you expect to exceed the threshold soon. It may be less attractive if your customers are consumers or small non-VAT-registered businesses, because VAT can make your prices look higher or reduce your margins.

This guide explains the pros and cons before you register early.

What is voluntary VAT registration?

Voluntary VAT registration means registering for VAT before you are legally required to do so.

Once registered, your business must follow VAT rules in the same way as a business that registered because it crossed the threshold. That usually means you must:

charge VAT on VATable sales at the correct rate
issue VAT invoices where required
keep VAT records
submit VAT returns
pay VAT owed to HMRC
follow Making Tax Digital rules where applicable
understand which costs have recoverable VAT

GOV.UK’s How VAT works guide explains that VAT-registered businesses must include VAT in the price of goods and services at the correct rate, keep records of VAT paid on purchases, report VAT charged and paid through VAT returns, and pay any VAT owed to HMRC.

So voluntary registration is not just a badge. It changes how your business prices, invoices, records and reports.

Quick answer: should you register below the VAT threshold?

You should consider voluntary VAT registration if most of your customers are VAT registered, your business has significant VATable costs, or you expect to cross the threshold soon.

You should be more cautious if most of your customers are private individuals, landlords, charities or small businesses that cannot reclaim VAT. In those cases, adding VAT may make your prices less competitive unless you absorb the cost yourself.

The decision usually depends on four questions:

Can your customers reclaim VAT?
Do you pay much VAT on your business costs?
Can your pricing absorb VAT without damaging sales?
Can your bookkeeping handle VAT returns properly?

If the answer to these questions is unclear, get advice before registering.

The main benefit: reclaiming VAT on business costs

One of the main reasons to register voluntarily is that VAT-registered businesses can usually reclaim VAT on eligible business purchases.

This can matter if you have large startup or growth costs, such as:

tools
machinery
vans
equipment
stock
materials
software
professional fees
office fit-out costs
website development
marketing costs

For example, a trades business buying tools, a construction company buying materials, or an ecommerce business buying stock may have significant VAT on costs. Voluntary registration may allow some of that VAT to be reclaimed, subject to the VAT rules.

GOV.UK’s Charge, reclaim and record VAT guidance is the useful outgoing link here. It explains the core process of charging VAT, reclaiming VAT and keeping VAT records.

This section could also internally link to Merranti’s previous blog post: “What Expenses Can a Limited Company Claim? A Practical Guide for UK Directors”, because VAT recovery and expense claims often overlap.

The second benefit: looking more established

Some businesses register voluntarily because VAT registration can make them look more established.

This may help if you work mainly with:

larger companies
commercial clients
public sector bodies
agencies
contractors
procurement teams
VAT-registered customers

Some larger customers expect suppliers to be VAT registered. In a business-to-business market, VAT registration may make little difference to the customer’s final cost if they can reclaim VAT.

However, this is not a strong enough reason by itself. VAT registration should still make commercial and financial sense.

For limited companies trying to look more established and improve financial systems, link internally to Merranti’s Limited Company Accounting page.

The third benefit: preparing before you cross the threshold

If your business is close to the VAT threshold, voluntary registration can help you prepare before registration becomes urgent.

That can give you time to:

adjust prices
update invoice templates
set up VAT in accounting software
review payment terms
train staff
explain VAT to customers
review VATable and exempt sales
start setting aside VAT cash
choose whether any VAT scheme is suitable

This can be better than discovering late that your rolling 12-month taxable turnover has already crossed the threshold.

For the official threshold rules, link out to GOV.UK’s Register for VAT page. GOV.UK explains the £90,000 threshold, the 12-month test, the 30-day future turnover test, late registration and temporary threshold exceptions.

The main downside: your prices may look higher

The biggest downside of voluntary VAT registration is pricing.

If you sell to VAT-registered businesses, VAT may not be a major issue because they can often reclaim the VAT you charge.

If you sell to consumers or non-VAT-registered customers, VAT can make your price look higher.

For example, if you currently charge £1,000 and then add VAT at 20%, the customer sees £1,200. If your competitors are not VAT registered and charge £1,000, you may look more expensive.

Your options are usually:

increase the price to include VAT
keep the customer-facing price the same and absorb the VAT
change pricing gradually
target more VAT-registered customers
review margins before registering

Absorbing VAT can seriously reduce profit margin. This is why voluntary registration should be reviewed with pricing, not just tax.

For official VAT rate information, link out to GOV.UK’s VAT rates page.

The second downside: more admin and record keeping

VAT registration adds admin.

You need accurate records of:

VAT charged on sales
VAT paid on purchases
VAT invoices
VAT returns
VAT payments
VAT adjustments
credit notes
reverse charge transactions
import VAT, where relevant
exempt, zero-rated or outside-scope sales, where relevant

This means bookkeeping must be kept up to date. If records are poor, VAT returns can become stressful and error-prone.

For businesses already struggling with bookkeeping, voluntary VAT registration may create more problems than benefits.

This section can link internally to the previous post: “The Most Common Bookkeeping Mistakes Small Business Owners Make.”

It should also link to Merranti’s Accounting Software and Cloud Accounting pages if those pages are live, because VAT records work best when the software is configured correctly.

The third downside: VAT affects cash flow

VAT collected from customers is not business profit. It may need to be paid to HMRC after offsetting recoverable input VAT.

A VAT-registered business needs to understand:

how much VAT it is collecting
how much VAT it can reclaim
when VAT returns are due
when VAT payments are due
whether customer payment delays will affect VAT cash
whether cash accounting could help

Cash flow matters because VAT can create timing pressure. You may need to pay VAT to HMRC before some customers have paid you, depending on the VAT scheme and accounting basis used.

GOV.UK’s How VAT works guidance explains that VAT returns usually report VAT charged to customers and VAT paid to other businesses every 3 months.

This section should link internally to Merranti’s previous post: “Why Your Profit Is Not the Same as Your Cash in the Bank.” VAT is one of the clearest examples of why bank balance, profit and tax liabilities are different.

It should also link to Merranti’s Financial & Management Accounts page because cash-flow projections and forecasting help businesses prepare for VAT payments.

Business-to-business vs business-to-consumer: the key distinction

The customer base is often the deciding factor.

If you sell mainly to VAT-registered businesses

Voluntary registration may be easier to justify.

Your customers may be able to reclaim the VAT you charge, so the VAT does not necessarily increase their final cost. You may also be able to reclaim VAT on your own costs.

This can suit:

consultants working with companies
B2B service providers
construction businesses working for VAT-registered contractors
wholesalers
agencies
manufacturers
commercial suppliers

If you sell mainly to consumers

Voluntary registration may be harder to justify.

Private customers usually cannot reclaim VAT, so VAT increases the final price they pay unless you reduce your net price.

This can affect:

retail
hospitality
personal services
domestic trades
consumer ecommerce
health and wellbeing services
small local services

That does not mean voluntary registration is always wrong for consumer-facing businesses. It means the pricing and margin impact must be modelled carefully.

VAT rates and exempt sales need checking

Not every sale is treated the same for VAT.

Some sales are standard-rated, some are reduced-rated, some are zero-rated, some are exempt, and some may be outside the scope of VAT.

This matters because taxable turnover includes standard-rated, reduced-rated and zero-rated sales, but the treatment of exempt and outside-scope sales is different.

GOV.UK’s Register for VAT page explains that taxable turnover includes zero-rated, reduced-rated and standard-rated goods and services. GOV.UK’s VAT rates page is useful for checking VAT treatment by category.

If your business has mixed supplies, voluntary registration needs extra care. For example, a business with both taxable and exempt activities may not be able to reclaim all VAT on costs.

VAT schemes may affect the decision

Some VAT schemes can affect how VAT is calculated and paid.

Depending on your business, you may need to review:

Cash Accounting Scheme
Flat Rate Scheme
Annual Accounting Scheme
retail schemes
margin schemes
domestic reverse charge rules, where relevant

These schemes can change admin, cash-flow timing or how VAT is calculated.

For official scheme information, link out to GOV.UK’s VAT schemes guidance.

Do not assume a scheme is suitable just because it sounds simpler. Some schemes can be helpful for certain businesses and poor value for others.

A practical checklist before registering voluntarily

Before registering for VAT below the threshold, ask:

What is my taxable turnover for the last 12 months?
How close am I to the £90,000 threshold?
Are my customers mainly VAT registered?
Would my customers accept VAT on top of my current prices?
Would I need to absorb VAT and reduce my margin?
How much VAT do I pay on business costs?
Are my sales standard-rated, reduced-rated, zero-rated, exempt or outside scope?
Could I reclaim meaningful VAT on startup or equipment costs?
Is my bookkeeping accurate enough for VAT returns?
Could a VAT scheme help or hurt?
How will VAT affect cash flow?
Would registering now make the eventual threshold crossing easier?

This checklist should be completed before the VAT application is submitted.

When voluntary VAT registration may make sense

Voluntary VAT registration may make sense where:

most customers are VAT-registered businesses
the business has significant VATable purchases
the business is close to the VAT threshold
the business wants to reclaim VAT on major setup costs
pricing can be adjusted without losing customers
bookkeeping software is ready
cash-flow forecasts include VAT payments
the business wants to appear established in a B2B market

When voluntary VAT registration may not make sense

Voluntary VAT registration may not make sense where:

most customers are private individuals
customers cannot reclaim VAT
margins are already tight
competitors are not VAT registered
the business has few VATable costs
bookkeeping is poor
pricing cannot be increased
VAT returns would create unnecessary admin
cash flow is already under pressure

The decision should be based on numbers, not guesswork.
