Do I Need to Register for VAT? Complete Guide

January 2026
7 min read

VAT registration is a critical decision for UK businesses. Understanding when you must register, when you can voluntarily register, and the implications of both choices will help you make the right decision for your business.

The VAT Registration Threshold

£90,000

Current VAT registration threshold for 2024/25

You must register for VAT if your VAT taxable turnover exceeds £90,000 in a rolling 12-month period, or if you expect it to exceed this threshold in the next 30 days alone.

Taxable turnover includes all standard and reduced-rate supplies, but excludes exempt supplies. Once you cross the threshold, you have 30 days to register with HMRC.

When You Must Register for VAT

You've Exceeded the Threshold

At the end of any month, if your total VAT taxable turnover for the previous 12 months exceeded £90,000, you must register within 30 days.

You Expect to Exceed It Soon

If you expect your taxable turnover to exceed £90,000 in the next 30 days alone, you must register before the 30-day period begins.

EU Sales or Acquisitions

You must register if you acquire goods from EU member states worth more than £90,000 in a year, even if your UK sales are below the threshold.

Voluntary VAT Registration

You can voluntarily register for VAT even if your turnover is below £90,000. This might benefit you if:

Reclaim Input VAT

You can reclaim VAT on business purchases and expenses, which can significantly reduce costs if you have high overheads.

Professional Image

Being VAT registered can make your business appear more established and professional, especially when dealing with B2B clients.

B2B Customers

If your customers are VAT registered, they can reclaim VAT on purchases from you, making your prices effectively the same as competitors.

Future Planning

If you expect to exceed the threshold soon, registering early avoids the administrative burden of backdating invoices.

When NOT to Register Voluntarily

Voluntary VAT registration might not be beneficial if:

  • You sell mainly to consumers (B2C) - They can't reclaim VAT, so your prices become 20% more expensive
  • You have low business expenses - Little VAT to reclaim means mostly administrative burden
  • You make exempt supplies - Financial services, insurance, education, healthcare
  • You want to keep things simple - VAT adds complexity: quarterly returns, Making Tax Digital compliance

VAT Schemes to Consider

Flat Rate Scheme

Pay a fixed percentage of your turnover to HMRC instead of tracking every expense. Available if turnover is under £150,000.

Good for: Service businesses with low material costs

Cash Accounting Scheme

Account for VAT when you receive or make payments, rather than when invoices are issued. Helps with cash flow.

Good for: Businesses with long payment terms or late-paying customers

Annual Accounting Scheme

Submit one VAT return per year instead of four. Make advance payments based on previous year's VAT bill.

Good for: Businesses wanting less frequent reporting
