VAT Threshold Planning: Register Early or Wait for £90,000?

What the Rules Actually Say

Under the Value Added Tax Act 1994, Schedule 1, you are legally required to register for VAT once your taxable turnover exceeds £90,000 in any rolling 12-month period, or if you reasonably expect it to exceed £90,000 in the next 30 days alone. Once you cross that line, you must notify HMRC within 30 days. Miss that deadline and HMRC can charge a late registration penalty based on the VAT you should have been collecting. HMRC's guidance on registration thresholds is published at VAT Notice 700/1.

The Case for Waiting

For many freelancers and sole traders, staying below the threshold is a genuine competitive advantage. If your clients are predominantly consumers or small businesses that cannot reclaim VAT, adding 20% to your invoices can price you out of the market. A freelance copywriter charging £80,000 a year to small business clients has a strong reason to monitor turnover carefully and, if possible, stay under the limit.

• You avoid the administrative burden of quarterly VAT returns (or monthly if HMRC directs).
• You keep your pricing simpler and more competitive for non-VAT-registered clients.
• You have no obligation to charge, collect, or remit VAT to HMRC.

Be cautious, however. HMRC looks at rolling 12-month turnover, not tax years. You must check your total at the end of every month. A sudden spike — a large project, a retainer starting mid-year — can push you over quickly. Failing to register on time is not a defence if you simply weren't watching.

The Case for Registering Voluntarily

HMRC allows voluntary registration below the threshold under the Value Added Tax Act 1994, Section 3 and Schedule 1, paragraph 9. This can be financially worthwhile in several situations.

• You have significant input VAT to reclaim. If you buy equipment, software, or materials subject to VAT, registering lets you reclaim that VAT from HMRC. A photographer spending £15,000 on cameras and lenses could reclaim £2,500 in input tax.
• Your clients are VAT-registered businesses. They reclaim the VAT you charge, so the 20% addition is cost-neutral to them. Early registration signals professionalism and doesn't cost your clients anything.
• You are approaching the threshold rapidly. Registering a few months early avoids a rushed application and gives you time to update your invoicing systems and contracts.

Flat Rate Scheme: Worth Considering?

If you do register, HMRC's Flat Rate Scheme (FRS) may reduce your admin and, in some cases, your VAT bill. Under the scheme, you charge clients VAT at 20% but pay HMRC a fixed percentage of your gross turnover — the rate depends on your trade sector. HMRC publishes the full list of flat rates in VAT Notice 733. Note: the Limited Cost Trader test (introduced in 2017) applies a 16.5% flat rate to most service-based freelancers, which significantly reduces the financial benefit of FRS for those with low VAT-able costs. Run the numbers for your specific situation before assuming FRS saves you money.

Practical Steps to Take Now

• Set up a simple spreadsheet or use your accounting software to track rolling 12-month taxable turnover — update it every month without fail.
• If you are within £15,000–£20,000 of the threshold, speak to an accountant now, not when you breach it.
• Review your client base: are they VAT-registered? If yes, voluntary registration is far less likely to harm your competitiveness.
• If you register, apply online via your HMRC business tax account. HMRC aims to process applications within 30 working days, though delays can occur — factor this into your timeline.

A Note on Current Figures

The £90,000 threshold was confirmed in the Spring Budget 2024 and applies for 2024/25 and 2025/26. As of the date of this article (September 2026), HMRC has not publicly announced a change to this threshold for 2026/27. You should verify the current threshold directly with HMRC's guidance before making decisions, as fiscal events can alter thresholds with relatively short notice.
