How to Register for VAT in the UK: Step-by-Step Guide (2026)

When Must You Register for VAT? VAT registration becomes mandatory when your **taxable turnover in any rolling 12-month period exceeds £90,000** (the threshold since April 2024). You must register within 30 days of exceeding the threshold — HMRC can backdate liability and add penalties for late registration.

Voluntary registration is possible at any turnover level if you make taxable supplies. Reasons to register voluntarily: - Your customers are VAT-registered businesses (they reclaim input VAT — your registration makes you competitive) - You make large purchases on which you want to reclaim input VAT - It signals a more established business to clients

The 3 Main VAT Schemes **1. Standard VAT Accounting**: Charge 20% on sales, reclaim VAT on purchases, pay the difference to HMRC quarterly. Simple in principle, complex in bookkeeping.

2. Flat Rate Scheme (FRS): Pay a fixed % of gross turnover to HMRC (typically 8-14.5% depending on your trade). No need to track input VAT on purchases — simpler bookkeeping. Potentially more profitable if your actual input VAT is low. Limited cost traders pay 16.5%. Available for businesses with turnover ≤£150k.

3. Cash Accounting: Account for VAT based on when you receive/make payment rather than invoice date. Helps cash flow for businesses with slow-paying customers. Available for turnover ≤£1.35M.

How to Register 1. Log in to your HMRC business tax account (or create one at gov.uk/government/organisations/hm-revenue-customs) 2. Select 'Register for VAT' 3.

What Happens After Registration - Charge VAT on all taxable supplies from registration date - Issue VAT invoices showing your VAT number and VAT amount - Submit VAT returns quarterly via MTD-compatible software - Keep VAT records for 6 years

Note: You cannot backdate reclaiming input VAT on purchases before your registration date (except for business assets purchased in the 4 years before registration, and services in the 6 months before).
