Running a small business or working for yourself means every pound counts, and so does every rule HMRC sets. One of the most important things to understand in 2025 is the VAT threshold. Whether you’re a café owner, tradesperson, freelancer, or sole trader, knowing when you must register for VAT, what happens if you cross the threshold, and how to plan around it could save you both money and stress.
In this guide, we’ll break down the VAT registration threshold for 2025 in clear, simple terms, explore what it means for small businesses and the self-employed, and answer the key questions you’re already asking.
What Is the VAT Threshold?
The VAT threshold is the level of annual VAT-taxable turnover at which a business must register for Value Added Tax.
For the 2025/26 tax year, the VAT threshold is £90,000, meaning that if your rolling 12-month taxable turnover goes over this amount, you’re legally required to register for VAT.
You must also register if:
- You expect turnover to exceed £90,000 in the next 30 days (for example, you secure a large contract).
- You make taxable supplies in the UK, including standard-rated (20%) and reduced-rated (5%) goods or services.
Turnover does not include income from VAT-exempt sales such as insurance, education, or health services.
The deregistration threshold is set at £88,000. This means that if your taxable turnover drops below £88,000, you can apply to deregister for VAT.
The UK’s VAT threshold is one of the highest in the world, sitting well above EU and OECD averages, which means millions of small UK businesses remain outside the VAT system altogether.
VAT Registration Threshold 2025
If you are trading in the UK, you must register for VAT if:
- Your taxable turnover exceeded £90,000 in the last 12 months.
- You expect turnover in the next 30 days to exceed £90,000.
The process involves registering through your Government Gateway account, providing details such as:
- Business name and nature of activity.
- Unique Taxpayer Reference (UTR).
- National Insurance number (if you’re a sole trader).
- Bank details.
- Expected turnover.
Once you submit your registration, HMRC typically issues your VAT certificate within 30 days, confirming your VAT number and when you must file your first return.
Failing to register on time can lead to backdated VAT charges, penalties, and interest, making it crucial to monitor your turnover carefully.
VAT Threshold for Small Businesses in 2025
For many small businesses, the VAT threshold is a double-edged sword. On the one hand, it provides relief from VAT compliance until turnover reaches £90,000. On the other hand, once crossed, it can significantly affect profitability.
Take a small café, florist, or hairdresser. Their sales might hover around £85,000–£95,000 annually. Crossing the VAT threshold could mean:
- Increasing prices by 20% (and risking losing customers), or
- Absorbing the VAT cost, which reduces profits.
Compliance costs also add up:
- Keeping digital VAT records.
- Subscribing to accounting software under Making Tax Digital (MTD) rules.
- Hiring accountants or bookkeepers.
While VAT registration allows businesses to reclaim VAT on purchases, the extra admin and higher customer prices often create a growth barrier for small enterprises.
VAT Threshold for Sole Traders & the Self-Employed
The VAT threshold doesn’t just affect incorporated businesses. Sole traders and the self-employed must also register once their taxable turnover passes £90,000.
For example, a self-employed plumber or freelance web designer could quickly hit the threshold if they secure several large contracts in a short time.
Case Study: Self-Employed Florist
A florist turning over exactly £90,000 a year with net profits of £31,400 decides to hire part-time staff. If her turnover nudges above the VAT threshold, she must register. To maintain her profit level, she may need to increase turnover by over 60% to cover both staff wages and VAT liabilities.
This shows why many sole traders deliberately keep turnover below £90,000, sometimes by cutting back hours, refusing larger contracts, or limiting marketing efforts.
Will the VAT Threshold Increase in 2026?
The VAT registration threshold was raised in April 2024, moving from £85,000 to £90,000. This change was announced in the Spring Budget 2024 to ease the burden on small businesses.
For 2026, no official government announcement has been made yet. Future increases will depend on economic conditions and government policy. Some commentators expect the threshold to remain frozen, while others argue it should rise in line with inflation to prevent more small businesses being drawn into VAT.
What Are the VAT Periods for 2025?
VAT returns are usually filed quarterly. Each quarter ends on the last day of the month, with submission and payment due just over a month later.
Here are the VAT return deadlines for 2025:
| VAT Period | Quarter End Date | Submission & Payment Deadline |
| Q1 (Jan – Mar) | 31 March 2025 | 7 May 2025 |
| Q2 (Apr – Jun) | 30 June 2025 | 7 August 2025 |
| Q3 (Jul – Sep) | 30 September 2025 | 7 November 2025 |
| Q4 (Oct – Dec) | 31 December 2025 | 7 February 2026 |
Some businesses use monthly or annual accounting schemes, but most small businesses follow the quarterly cycle.
How to Avoid the VAT Threshold (Legally)
It’s important to be clear: there is no legal way to “dodge” VAT if your taxable turnover exceeds £90,000. HMRC requires registration once you cross the threshold, and failing to comply can lead to penalties.
That said, many small business owners manage their affairs carefully to stay below the line:
- Monitor turnover monthly: Use accounting software to track rolling 12-month turnover.
- Adjust invoicing timings: Delaying or bringing forward invoices can sometimes help manage the 30-day rule, though this must be done responsibly.
- Stay under the deregistration threshold: If turnover drops below £88,000, you may apply to deregister.
- Consider voluntary registration earlier: Rather than aiming to avoid VAT, some businesses choose to register proactively, turning the rules to their advantage.
It’s worth noting that deliberately turning down contracts, reducing trading hours, or restricting marketing to stay below £90,000 can hold your business back. This is often referred to as the “VAT growth trap”.
What Happens If I Just Go Over the VAT Threshold?
Crossing the VAT threshold, even by a small amount, means you must register. You are given 30 days from the end of the month in which you exceeded the threshold to notify HMRC.
Here’s what happens if you go over:
- Backdated registration: VAT is due from the date you crossed the line.
- VAT on past sales: You may have to account for VAT on sales already made if you failed to register on time.
- Penalties & interest: HMRC can charge fines for late registration.
- Customer pricing impact: You’ll either need to increase your prices or absorb the 20% VAT cost, which reduces profit margins.
On the positive side, registration means you can reclaim VAT on eligible business purchases, improving cash flow. For businesses with significant expenses, this can offset some of the costs.
Voluntary VAT Registration in 2025
You don’t have to wait until you hit £90,000 turnover to register. Many small businesses and sole traders choose to register voluntarily.
Advantages of voluntary VAT registration:
- Ability to reclaim VAT on business expenses.
- Increased credibility with other businesses and clients.
- Keeps pricing competitive if most of your customers are VAT-registered themselves.
Disadvantages:
- Customers who aren’t VAT-registered must pay higher prices.
- More admin under Making Tax Digital (MTD).
- Accounting and compliance costs.
Whether voluntary registration is right depends on your customer base and expense levels. If most of your clients are VAT-registered businesses, it’s often a smart move.
Making Tax Digital (MTD) for VAT
Since April 2022, all VAT-registered businesses (including those registered voluntarily) must follow the rules of Making Tax Digital for VAT.
This means:
- Keeping digital VAT records.
- Filing VAT returns through HMRC-approved software.
- Ensuring VAT records are accurate and up to date.
While this adds some admin, many businesses find that accounting software improves accuracy, saves time, and makes cash flow management easier.
The Hidden Costs and Challenges of VAT Registration
Registering for VAT doesn’t just affect your tax bills; it also introduces hidden costs and administrative challenges:
- Record-keeping burden: Small business owners must track VAT on every sale and purchase.
- Software & training costs: Digital record-keeping requires investment in software and training.
- Professional fees: Many hire accountants to manage VAT compliance, which can cost thousands per year.
These challenges create what many call the “psychological barrier” of VAT — the fear of crossing the threshold and being pulled into a more complex tax system. As a result, some small businesses cap their growth to avoid it, unintentionally holding back their long-term potential.
