The UK VAT registration threshold has again come under scrutiny following fresh analysis of HMRC administrative data showing a growing concentration of small businesses operating just below the registration limit.
The current threshold requires businesses to register for VAT once their taxable turnover exceeds £90,000 within a rolling 12 month period. Crossing that point brings VAT collection obligations and ongoing reporting requirements. For many smaller firms, the change can also affect pricing and competitiveness.
Evidence from HMRC data indicates that many businesses actively manage their turnover to remain below the threshold. Economists and tax policy analysts have long identified this behaviour as a distortion within the tax system, where operational decisions are influenced by tax rules rather than market demand.
Evidence of businesses clustering below the VAT threshold
Analysis of VAT registration data shows a clear concentration of businesses with annual turnover just below the £90,000 threshold.
According to analysis of HMRC VAT statistics by advisers reviewing the data, 683,700 UK businesses reported turnover below the £90,000 VAT threshold in the year to December 2025, up from 671,100 the previous year.Over the same period, the number of firms reporting turnover between £90,000 and £150,000 fell from 306,300 to 280,400.
The figures suggest a growing concentration of businesses operating just below the registration threshold, suggesting some may be managing their activity levels as turnover approaches the registration point.
Reported behaviours include limiting additional work once turnover approaches the threshold, declining new contracts and slowing expansion plans, most frequently among sole traders and micro-businesses where pricing flexibility is limited.
Why the VAT threshold creates a growth barrier
The UK VAT threshold is relatively high compared with many other countries. While this reduces the compliance burden for very small businesses, it also creates a pronounced “cliff edge” where a small increase in turnover triggers full VAT obligations.
Once the threshold is exceeded, a business becomes responsible for VAT registration and periodic reporting. In addition, the business may need to increase prices where VAT cannot be absorbed within existing margins.
Where customers are mainly individuals rather than VAT-registered businesses, passing on the additional cost can be difficult. A firm that previously charged £100 for a service may effectively need to charge £120 after VAT registration unless margins absorb the tax.
For price-sensitive sectors, this can affect competitiveness and customer demand.
Sectors most affected by the VAT cliff edge
The threshold effect is most visible in sectors where businesses sell primarily to consumers rather than other VAT registered businesses:
- Construction and local trades.
- Hair and beauty services.
- Hospitality and catering.
- Personal services and home services.
- Freelance and creative work.
In these sectors, customers typically cannot reclaim VAT. Businesses therefore face a direct pricing challenge once registration becomes necessary.
Ongoing policy debate over the VAT threshold
The behavioural impact of the VAT threshold has been recognised in tax policy discussions for many years. Economists and business groups have proposed different approaches to reduce the distortion.
One proposal is to increase the threshold further, allowing small firms to expand before facing VAT obligations. Some commentators suggest a threshold of around £115,000 would reduce the number of firms limiting growth.
Another approach would involve lowering the threshold while simplifying VAT administration so that registration becomes a more routine part of operating a business.
Neither option has been adopted by the government. The current threshold of £90,000 therefore continues to shape operational decisions for many small UK businesses.
What this means for SMEs approaching the threshold
For many small firms, the VAT threshold remains a practical consideration in business planning.
As turnover approaches £90,000, business owners often review how VAT registration could affect pricing, demand and administrative requirements. These considerations can influence hiring decisions, expansion plans and pricing strategy.
Until the policy framework changes, the VAT registration threshold will remain a defining feature of the operating environment for many UK small businesses.
