VAT registration: when do you need to think about it?

When must you register for VAT?

You must register for VAT if, at the end of any month, your total taxable turnover over the previous 12 months exceeds the registration threshold (currently £90,000) — or if you expect it to exceed that figure in the next 30 days alone.

Registration is mandatory once those tests are met, whether or not you’re actively planning for it. Getting this wrong carries penalties, so if you’re close to the threshold, it’s worth tracking carefully.

What happens when you register?

VAT registration has real consequences for your business:

• Pricing. If your customers aren’t VAT-registered themselves, adding 20% to your prices makes you more expensive. Often you’ll need to decide whether to absorb the VAT or increase your prices.
• Cash flow. You’ll collect VAT from customers and pay it to HMRC — typically each quarter. Meanwhile VAT you pay on business purchases can usually be reclaimed. Getting the timing right matters.
• Record keeping. MTD for VAT means keeping digital records and filing returns using compatible software. If you’re already using cloud accounting, you’re likely most of the way there.

Is VAT always bad news?

No. If most of your customers are VAT-registered businesses, they can reclaim the VAT you charge — so VAT is largely neutral for them. In that situation, registering can make you look more established and lets you reclaim VAT on your own purchases.

There are also schemes that can help small businesses, including:

• Flat Rate Scheme — instead of accounting for VAT on every sale and purchase, you pay a fixed percentage of turnover. For businesses with low VAT-bearing costs, this can mean keeping more of what you collect.
• Cash accounting — account for VAT when you’re paid, not when you invoice, which helps with customers who pay late.

When voluntary registration makes sense

You may be able to register for VAT voluntarily even below the threshold. Common reasons include:

• Your customers are all VAT-registered, so it’s cost-neutral for them
• You reclaim VAT on significant purchases (for example, refitting a shop or buying equipment)
• You buy property or other high-value assets where the VAT is substantial

Planning ahead

The right answer depends entirely on your numbers, your customers and your cash flow. We regularly help businesses decide whether to register, which VAT scheme to use, and how to price through the change.
