Do You Need to Register for VAT? (UK 2026 Explained)

VAT registration is mandatory once your turnover exceeds £90,000 — but many businesses choose to register voluntarily long before reaching that threshold.

Understanding when to register, how it affects your prices, and whether voluntary registration makes sense can save you time, money, and compliance headaches.

At Brightson Accounting in Wolverhampton, we help businesses across the West Midlands navigate VAT registration and compliance.

This guide explains everything you need to know about VAT in 2026.

What Is the VAT Threshold in 2026?

You must register for VAT if your taxable turnover exceeds £90,000 in any rolling 12-month period (2026/27 tax year).

Taxable turnover means:

• Total sales of goods and services subject to VAT
• Excludes VAT-exempt items (insurance, financial services, education, etc.)

You must register within 30 days of exceeding the threshold.

When Should You Register?

Mandatory Registration:

You must register if:

• Your turnover in the last 12 months exceeded £90,000
• You expect your turnover to exceed £90,000 in the next 30 days

Voluntary Registration:

You can register even if you're below the threshold.

Why would you?

• To reclaim VAT on business purchases (equipment, stock, services)
• To appear more professional and established
• If your customers are VAT-registered businesses (they can reclaim it anyway)

From what we see with clients in Wolverhampton, most B2B businesses (consultants, contractors, agencies) register voluntarily around £30,000–£50,000 turnover.

How to Register for VAT

Step 1: Check Eligibility

Confirm your turnover and decide on your VAT scheme (see below).

Step 2: Register Online

Visit: gov.uk/register-for-vat

You'll need:

• Your business details (name, address, UTR, company number if limited)
• Bank details
• Turnover estimates
• Start date for VAT registration

Step 3: Receive Your VAT Number

HMRC will send you:

• A VAT registration certificate (within 2-4 weeks)
• Your VAT number (9 digits)

Once registered, you must display your VAT number on all invoices.

How VAT Works

Charging VAT (Output Tax):

You charge VAT on your sales (usually 20%).

Example:

• Service price: £1,000
• VAT at 20%: £200
• Total invoice: £1,200

Reclaiming VAT (Input Tax):

You can reclaim VAT on business purchases.

Example:

• Buy a laptop: £1,000 + £200 VAT = £1,200
• You can reclaim the £200 from HMRC

Paying HMRC:

Every quarter, you pay HMRC:

• VAT charged on sales (output tax)
• Minus VAT paid on purchases (input tax)

If you've paid more VAT than you charged, HMRC refunds the difference.

VAT Schemes

Standard VAT Accounting:

Default scheme — charge 20% VAT, reclaim VAT on purchases, file quarterly returns.

Flat Rate Scheme:

Pay a fixed percentage of turnover to HMRC (based on your industry).

Pros:

• Simpler admin
• Can save money if you have low expenses

Cons:

• You can't reclaim VAT on most purchases

Cash Accounting:

Pay VAT when you receive payment (not when you issue an invoice).

Good for businesses with long payment terms.

VAT Returns and Deadlines

You must file a VAT return every quarter — 1 month + 7 days after the end of your VAT period.

Example:

• VAT period: 1 Jan – 31 Mar
• Deadline: 7 May

All returns must be filed online via Making Tax Digital (MTD) software.

Should You Register Voluntarily?

Register If:

• Most of your customers are VAT-registered businesses (they can reclaim VAT)
• You're making large VAT-able purchases (equipment, stock, vehicles)
• You want to appear more professional

Don't Register If:

• Most of your customers are individuals/consumers (they can't reclaim VAT)
• Your profit margins are low
• You want to keep prices low and competitive

Many small businesses we work with in Birmingham and the West Midlands stay below the threshold deliberately to avoid VAT complexity.

What If You Exceed the Threshold Accidentally?

If you go over £90,000 unexpectedly:

• Register within 30 days
• HMRC will backdate your registration to the date you exceeded the threshold
• You may need to pay VAT retrospectively on sales made after that date

Monitor your turnover carefully — set up accounting software to track it monthly.

VAT and Starting a Business

Most new businesses don't need to worry about VAT in their first year.

Focus on:

• Getting your business structure right
• Registering as self-employed or forming a limited company
• Setting up bookkeeping and accounting software
• Understanding your tax obligations
