⏱️ 30-Second Summary
  • You must register for VAT once your taxable turnover passes £90,000 in any rolling 12-month period — or if you expect to pass it in the next 30 days alone.
  • Registration is done online through HMRC via your Government Gateway account, and you'll get a VAT number back (usually within a few weeks).
  • You can also register voluntarily below the threshold to reclaim VAT on your costs — sometimes worth it, sometimes not.
  • After registering you must charge VAT, issue VAT invoices, and file VAT returns under Making Tax Digital (MTD) using compatible software.
  • Miss the deadline and HMRC can charge a late-registration penalty plus the VAT you should have collected.

Registering for VAT is one of those jobs that feels far more intimidating than it actually is — until you miss the deadline, at which point it becomes expensive. This guide walks you through exactly when you need to register, how to do it step by step through HMRC, and what changes the day your registration goes live.

Who needs to register for VAT in the UK?

You must register for VAT with HMRC if any of the following apply:

  • Your VAT-taxable turnover exceeds £90,000 over any rolling 12-month period (this is the main test)
  • You expect to exceed £90,000 in the next 30 days alone
  • You're a business based outside the UK supplying goods or services to the UK (no threshold applies)

"Taxable turnover" means everything you sell that isn't VAT-exempt — including your zero-rated sales. It's not the same as profit, and it's not your calendar-year figure: it's a rolling total you should check at the end of every month, looking back over the previous 12.

What is the VAT registration threshold in 2026?

For 2026 the thresholds are unchanged from recent years:

Threshold Amount What it means
Registration £90,000 Pass this and you must register
Deregistration £88,000 Fall below this and you can cancel

There are two ways you can be caught:

  • The backward look: at the end of any month your last 12 months' turnover tops £90,000. You must register within 30 days of the end of that month, and your registration takes effect from the first day of the following month.
  • The forward look: you realise on any day that you'll exceed £90,000 in the next 30 days by itself (a big one-off contract, say). You must register by the end of that 30-day period, effective from the date you realised.

Miss these and HMRC can charge a late-registration penalty and still demand the VAT you should have charged customers — money that often comes straight out of your own pocket.

Should you register for VAT voluntarily?

You can register even if you're below £90,000, and for some businesses it pays off. It's usually worth considering if:

  • You buy a lot of VAT-charged goods or services — registering lets you reclaim that input VAT
  • Most of your customers are VAT-registered businesses who can reclaim the VAT you charge them, so your prices don't really rise for them
  • You want the credibility of being VAT registered, or you're close to the threshold anyway

It's usually not worth it if you sell mainly to the public (who can't reclaim VAT, so a 20% price rise hits your competitiveness) and you have few costs to reclaim. It also adds admin — you'll be inside Making Tax Digital from day one.

How to register for VAT: step by step

Most businesses register online, and HMRC has been simplifying the process through 2026. Here's the flow:

1
Sign in to HMRC
Use your Government Gateway user ID (or create one) and go to "Register for VAT" in your online account.
2
Enter your details
Provide your business information, turnover, activity and bank details, and choose your VAT scheme.
3
Get your VAT number
HMRC reviews and issues your VAT registration number, usually within a few weeks, along with your VAT online account.

If you'd rather not deal with HMRC yourself, an accountant can register on your behalf as your agent — we do this daily, pick the right scheme for you, and make sure your effective date is correct so you don't over- or under-pay.

What you need to register

Have these ready before you start — it makes the whole thing far quicker:

  • Your Government Gateway user ID and password
  • Your Unique Taxpayer Reference (UTR)
  • Business bank account details
  • Details of your turnover and business activity (SIC code)
  • For a limited company: your company registration number and incorporation date
  • For a sole trader: your National Insurance number and ID

What happens after you register?

From your effective registration date you're in the VAT system, which means you must:

  • Charge VAT on your taxable sales — standard rate 20%, reduced 5%, or zero-rated 0% depending on what you sell
  • Issue valid VAT invoices showing your VAT number and the VAT charged
  • File VAT returns (usually quarterly) and pay any VAT due — the deadline is 1 month and 7 days after the end of each VAT period
  • Keep digital records and file through Making Tax Digital-compatible software
  • Reclaim the VAT you pay on business purchases (input VAT)

This is where most owners feel the admin. Our VAT return filing service handles the quarterly returns and MTD filing for you, so registering doesn't mean signing up for a new part-time job.

Which VAT accounting scheme should you choose?

You pick a scheme when you register, and it affects how much you pay and how much admin you do:

  • Standard accounting — you account for VAT on invoices as they're raised. The default.
  • Flat Rate Scheme — you pay a fixed percentage of turnover instead of tracking every transaction. Simple, and can save money for service businesses with low costs.
  • Cash Accounting — you only pay VAT once your customer has actually paid you, which helps cash flow.
  • Annual Accounting — one return a year with instalments, reducing paperwork.

Choosing the right one can genuinely change your bill — it's worth getting advice before you commit. If you also want to sense-check how VAT sits alongside your salary and take-home as a director, our UK Salary Calculator is a handy starting point.

Frequently asked questions

What is the VAT registration threshold in the UK for 2026?

£90,000 of VAT-taxable turnover over any rolling 12-month period. If you cross it you must register within 30 days. The deregistration threshold is £88,000. Both figures are unchanged for 2026.

How long does VAT registration take?

HMRC typically issues your VAT number within a few weeks of a complete online application, though it can take longer if they need to verify details. You should keep records and can usually start accounting for VAT from your effective date even before the number arrives.

Can I register for VAT voluntarily below £90,000?

Yes. Voluntary registration lets you reclaim VAT on your costs and can add credibility, and it often makes sense if your customers are VAT-registered businesses. It's usually less attractive if you sell mainly to the public and have few costs to reclaim.

What happens if I register for VAT late?

HMRC can charge a late-registration penalty based on how late you are and how much VAT was due, and you'll still owe the VAT you should have charged from your correct registration date — even if you never collected it from customers. Registering on time avoids both.

Do I have to file VAT returns online?

Yes. VAT returns must be filed digitally through Making Tax Digital-compatible software, with digital record-keeping. Most businesses file quarterly, with payment due one month and seven days after the end of each VAT period.
