Do I Need to Charge VAT? UK VAT Threshold for Freelancers Explained

"Do I need to charge VAT?" is one of the most common questions UK freelancers ask — and getting it wrong in either direction costs money. Charge VAT when you don't need to and you may put clients off; ignore it past the threshold and you face a bill plus penalties. This guide explains when you must register, when you might choose to, and what changes on your invoices once you do.

This is general information, not tax advice — check GOV.UK or an accountant for your circumstances.

The VAT Registration Threshold

You must register for VAT once your VAT-taxable turnover exceeds £90,000 in any rolling 12-month period (the threshold as of the 2024/25 tax year). It's not your tax-year figure — it's any 12 months on a rolling basis, so check it regularly as you grow.

You also have to register if you expect to go over £90,000 in the next 30 days alone. Once registered, you charge VAT on your invoices and pass it to HMRC, reclaiming VAT on your own business purchases.

Most freelancers starting out are well under £90,000 and don't need to charge VAT at all. If that's you, you simply don't add VAT — and you can say so on your invoice. (See our guide to invoicing when you're not VAT registered.)

Voluntary Registration: Pros and Cons

You can register voluntarily even below the threshold. Whether it's worth it depends on who your clients are.

Pros:

• Reclaim VAT on purchases — useful if you buy a lot of equipment, software or stock.
• Looks established — some businesses see a VAT number as a sign of a "real" company.
• Avoids a cliff edge — if you're growing fast, registering early smooths the transition.

Cons:

• 20% more expensive for some clients — if your clients are consumers or other non-VAT-registered businesses, they can't reclaim the VAT, so your prices effectively rise.
• More admin — VAT returns (usually quarterly) and stricter record-keeping.

Rule of thumb: if most of your clients are VAT-registered businesses, voluntary registration is often a net win (they reclaim the VAT, you reclaim yours). If your clients are consumers or small non-registered businesses, it usually isn't worth it until you have to.

The Flat Rate Scheme (Basics)

To simplify VAT for smaller businesses, HMRC offers the Flat Rate Scheme. Instead of tracking VAT on every purchase, you pay HMRC a fixed percentage of your VAT-inclusive turnover, with the percentage set by your industry. You still charge clients the normal 20%, but you keep the difference between that and your flat rate.

It can save admin and sometimes money, but it isn't right for everyone — particularly if you buy a lot of VAT-able goods (you lose most of the ability to reclaim that VAT). It's available to businesses with VAT-taxable turnover up to a set limit. Check whether it suits you before opting in.

What Changes on Your Invoices Once Registered

Once you're VAT registered, your invoices become VAT invoices and must show extra details:

• Your VAT registration number.
• The VAT rate applied to each item (standard 20%, reduced 5%, or zero).
• The VAT amount charged, and the total excluding and including VAT.
• A unique invoice number, the date (tax point) and the usual business details.

Frequently Asked Questions

What is the VAT threshold for freelancers in the UK? You must register for VAT once your VAT-taxable turnover exceeds £90,000 in any rolling 12-month period, or if you expect to exceed it in the next 30 days.

Do I have to charge VAT as a freelancer? Only if you're VAT registered. Most freelancers under the £90,000 threshold are not registered and don't add VAT to their invoices. You can register voluntarily below the threshold if it benefits you.

Should I register for VAT voluntarily? It often makes sense if most of your clients are VAT-registered businesses who can reclaim the VAT. It usually doesn't if your clients are consumers or non-registered businesses, because your prices effectively rise by the VAT.

What's the VAT Flat Rate Scheme? A simplified scheme where you pay HMRC a fixed percentage of your VAT-inclusive turnover instead of tracking VAT on every purchase. It cuts admin but suits businesses with few VAT-able purchases best.
