Do I Need to Register for VAT? A Simple Guide
A plain-English guide to VAT registration for small businesses in the UK. Based on HMRC published guidance — for general information only, not professional advice.
1. What is VAT?
Value Added Tax (VAT) is a tax charged on most goods and services sold in the UK. As a business, once registered you charge VAT to your customers and pay VAT on your business purchases. You then pay the difference to HMRC (or receive a refund if you paid more than you charged).
The standard rate is currently 20%, with a reduced rate of 5% for some items and a zero rate for others. Some goods and services are exempt entirely. Use our VAT calculator to quickly add or remove VAT from any amount.
Key distinction: VAT is a tax on the consumer, not the business. As a VAT-registered business, you are effectively collecting tax on behalf of HMRC. The VAT you charge is not your income — it's money you owe to HMRC.
2. The VAT registration threshold
The key number you need to know:
This means: if your VAT taxable turnover in any rolling 12-month period exceeds £90,000, you are generally required to register for VAT.
“VAT taxable turnover” includes most sales, but not VAT-exempt supplies. It's not the same as profit — it's total revenue from taxable sales. If you're unsure whether your income counts as VAT taxable, consult an accountant.
3. When you must register
There are two main triggers for compulsory registration:
Historic test (looking back)
At the end of any month, if your VAT taxable turnover for the past 12 months has exceeded the threshold, you must register within 30 days of the end of that month. Your registration is effective from the first day of the second month after you exceeded the threshold.
Future test (looking forward)
If at any point you expect your VAT taxable turnover to exceed the threshold in the next 30 days alone, you must register immediately. This often applies when you win a large contract or project.
Example: Historic test
- •On 30 June 2026, you check your last 12 months' turnover
- •July 2025 to June 2026 total = £93,000
- •This exceeds £90,000 — you must register by 30 July 2026
- •Your VAT registration is effective from 1 August 2026
Late registration can result in penalties. HMRC may charge you the VAT you should have been paying from the date you should have been registered. Monitor your turnover regularly.
4. Voluntary registration: pros and cons
Even if your turnover is below £90,000, you can choose to register for VAT voluntarily. This is a significant decision with trade-offs:
✓ Potential benefits
- Reclaim VAT on business purchases — equipment, software, professional fees, etc.
- Professional image — being VAT-registered can signal an established business
- No impact on B2B customers — VAT-registered clients can reclaim the VAT you charge
- Reclaim VAT from before registration — you may be able to reclaim VAT on goods bought up to 4 years before, and services up to 6 months before
✗ Potential drawbacks
- Higher prices for consumers — if you sell to non-VAT-registered individuals, your prices effectively increase by 20%
- Admin burden — quarterly VAT returns, Making Tax Digital compliance, record-keeping
- Cash flow impact — you collect VAT then pay it to HMRC quarterly
- MTD software costs — you need compatible accounting software
Rule of thumb: Voluntary registration tends to be more beneficial if you sell mainly to other businesses (B2B), have significant VAT-able business expenses, or are approaching the threshold anyway. If you sell mainly to consumers (B2C), it can make you less competitive on price. Discuss with an accountant before deciding.
5. VAT schemes to know about
HMRC offers several VAT schemes that can simplify administration or improve cash flow. Here are the main ones:
Flat Rate Scheme
Instead of calculating VAT on every transaction, you pay a fixed percentage of your gross turnover. The percentage varies by business type (e.g. 14.5% for IT consultants, 12% for photographers). Available if your VAT taxable turnover is £150,000 or less. Simpler but you generally cannot reclaim VAT on purchases (except capital goods over £2,000).
Cash Accounting Scheme
You account for VAT based on when you receive or make payments, rather than when you issue invoices. This can help cash flow if your customers are slow to pay. Available if your VAT taxable turnover is £1.35 million or less.
Annual Accounting Scheme
Instead of 4 quarterly returns, you submit one annual return and make interim payments throughout the year. This reduces admin but requires accurate cash flow management. Available if your turnover is £1.35 million or less.
The right scheme depends on your business type, turnover, expenses, and cash flow. An accountant can help you evaluate which (if any) would benefit you.
6. What happens after you register?
Once registered, you'll need to:
- 1.Charge VAT at the correct rate on your taxable goods and services from your registration date.
- 2.Issue VAT invoices showing your VAT number, the VAT rate, and the VAT amount separately.
- 3.Keep VAT records — a VAT account, copies of all VAT invoices issued and received, and records of all supplies and purchases.
- 4.Submit VAT returns — typically quarterly, via Making Tax Digital compatible software. Your return shows VAT charged minus VAT paid.
- 5.Pay HMRC the VAT owed (or receive a refund if you've paid more VAT on purchases than you charged on sales).
- 6.Use Making Tax Digital (MTD) — you must keep digital records and submit returns using MTD-compatible software. Spreadsheets alone are no longer sufficient.

7. Deregistration
You can apply to deregister from VAT if:
- •Your VAT taxable turnover drops below the deregistration threshold (currently £88,000 — different from the registration threshold)
- •You stop making taxable supplies entirely
- •You stop trading altogether
Note: When you deregister, you may need to account for VAT on any stock and assets you hold at the date of deregistration (if the total VAT would be more than £1,000). This is known as a deregistration charge. Discuss the implications with your accountant before deregistering.
Frequently asked questions
What is the current VAT registration threshold?
As of 2025/26, the VAT registration threshold is £90,000 of VAT taxable turnover in any rolling 12-month period. If your turnover exceeds this, you are generally required to register. The threshold may change — always verify on gov.uk.
Can I register for VAT voluntarily?
Yes, you can register for VAT voluntarily even if your turnover is below the threshold. This can be beneficial if you sell mainly to VAT-registered businesses (who can reclaim the VAT) or if you want to reclaim VAT on your own business purchases.
What is the Flat Rate Scheme?
The Flat Rate Scheme is a simplified way of paying VAT. Instead of calculating the exact VAT on each sale and purchase, you pay a fixed percentage of your gross turnover. The percentage depends on your business type. You cannot reclaim VAT on most purchases, but the scheme simplifies administration.
How often do I need to submit a VAT return?
Most VAT-registered businesses submit quarterly returns and payments. Your specific deadlines depend on your VAT accounting period. VAT returns must be submitted digitally through Making Tax Digital (MTD) compatible software.
What happens if I should have registered but did not?
If you should have registered for VAT but failed to do so, HMRC may charge you the VAT you should have been paying from the date you should have registered. You may also face penalties and interest. It is important to monitor your turnover and register promptly when required.
Can I deregister from VAT?
You can apply to deregister if your VAT taxable turnover drops below the deregistration threshold (currently £88,000). You may also deregister if you stop trading or making taxable supplies. Check HMRC guidance for the current deregistration threshold.
