Understanding Value Added Tax (VAT) is a common headache for many business owners. The biggest question is often the simplest: when do I actually need to register? Getting it wrong can lead to penalties and stress you don’t need. This guide will give you the current VAT threshold figures and explain exactly what they mean for your business, when you need to register, and how to calculate your turnover correctly.
The Current UK VAT Thresholds for 2025/26
To get straight to the point, here are the key figures you need to know. It’s crucial to remember that the main threshold is based on your VAT taxable turnover in a rolling 12-month period, not your standard financial or calendar year.
- VAT Registration Threshold: You must register for VAT if your total VAT taxable turnover for the last 12 months was over £90,000.
- VAT Deregistration Threshold: You can apply to deregister if your taxable turnover is expected to be £88,000 or less over the next 12 months.
Note: These figures are correct as of the 2024/25 tax year. Always check the official GOV.UK website for the most current figures for the tax year in question.
How to Calculate Your VAT Taxable Turnover
One of the most confusing parts of VAT is working out what counts towards the threshold. Your “taxable turnover” is the total value of all goods and services you sell that are not VAT exempt. It’s important to get this right.
- What to include: You must include the sales of all goods and services that have a standard, reduced, or zero rate of VAT. A common mistake is thinking that zero-rated items (like most food, books, or children’s clothes) don’t count towards the threshold. They absolutely do.
- What to exclude: You should exclude any income from sales of VAT-exempt items (such as postage stamps, insurance, or certain financial services) and any capital assets you sell (like a company van or computer).
Understanding the Rolling 12-Month Period
This is the single biggest mistake business owners make. The VAT threshold is not assessed against your annual accounts from April to March. Instead, you need to calculate your turnover on a rolling 12-month basis.
At the end of every single month, you should look back over the previous 12 months. For example, at the end of October, you need to add up your total taxable turnover from 1st November of the previous year to 31st October of the current year. If that total exceeds £90,000, you have crossed the threshold.
What to Do When You Cross the VAT Threshold
First of all, don’t panic. If you’ve been monitoring your turnover regularly, crossing the threshold won’t come as a surprise. HMRC has a clear process and timeframe for you to get registered.
The 30-Day Rule for VAT Registration
Once you cross the threshold, you have a specific deadline. You must register for VAT within 30 days of the end of the month in which you went over the limit. For example, if your turnover exceeded £90,000 on 15th August, the “end of the month” is 31st August. You would then have until 30th September to complete your registration.
You should also be aware of the “future-dated” test. If you have reason to believe your taxable turnover will exceed the threshold in the next 30 days alone (for instance, you’ve won a huge contract), you must register immediately.
Consequences of Late Registration
Failing to register on time can be costly. HMRC can issue a penalty that is calculated as a percentage of the VAT you owe from the date you should have been registered. On top of the penalty, you will also be required to pay all the VAT that you should have collected from your customers during that period. Staying on top of your figures is the best way to save yourself future stress and unexpected bills.

Voluntary VAT Registration: Is It Right for You?
You don’t have to wait until your turnover hits £90,000. Some businesses find it beneficial to register for VAT voluntarily, even when they are well below the threshold. However, it’s a strategic decision with both pros and cons.
Potential Benefits of Registering Voluntarily
- Reclaim VAT: The biggest advantage is that you can reclaim the VAT you pay on your business expenses, equipment, and stock.
- Business Image: Being VAT registered can make your business appear larger and more established, which can build trust with potential clients or suppliers.
- B2B Sales: If most of your customers are other VAT-registered businesses, they will be able to reclaim the VAT you charge them, so it won’t affect their purchasing decision.
Potential Drawbacks to Consider
- Higher Prices: You must add VAT to your sales. This makes your products or services more expensive for customers who are not VAT registered (like the general public), which could make you less competitive.
- Increased Admin: You must file regular VAT returns, usually every quarter. This adds to your administrative workload.
- Digital Records: As a VAT-registered business, you will be required to comply with Making Tax Digital (MTD) rules, which means keeping digital records and using compatible software to submit your returns.

How long does the VAT registration process take with HMRC?
Online applications are typically processed within 30 working days, though it can sometimes be quicker. Once processed, you will receive your VAT registration certificate, which includes your VAT number and your first return period.
What is Making Tax Digital for VAT?
