What Is VAT Registration?
VAT registration is the process by which a business registers with HMRC to charge, collect, and remit Value Added Tax. Once your taxable turnover exceeds the threshold, registration is compulsory.
Key Takeaways
- VAT registration becomes compulsory when your taxable turnover exceeds £90,000 in any rolling 12-month period.
- Once registered, you charge VAT (output tax) on your sales and reclaim VAT (input tax) on your purchases.
- You must submit VAT returns — usually quarterly — through HMRC's Making Tax Digital system.
- Voluntary registration can be beneficial even below the threshold, particularly if your customers are VAT-registered businesses.
When VAT registration is required
Value Added Tax (VAT) is a consumption tax charged on most goods and services in the UK at the standard rate of 20% (with reduced 5% and zero 0% rates applying to specific categories). Your business must register for VAT with HMRC when your taxable turnover — the total value of VATable sales, not your profit — exceeds £90,000 in any rolling 12-month period, or if you expect it to exceed £90,000 in the next 30 days alone. The threshold applies to the total of all VATable sales across all business activities. Once registered, you must charge VAT on your taxable supplies, issue VAT invoices, submit regular VAT returns, and pay any VAT due to HMRC. Failure to register on time can result in penalties calculated as a percentage of the VAT that should have been accounted for.
How VAT works for a registered business
Once registered, your business becomes a VAT collector on behalf of HMRC. You charge VAT on your sales (output tax) and can reclaim VAT on your business purchases (input tax). The difference between output tax and input tax is what you pay to (or reclaim from) HMRC on your VAT return. For example, if you charge clients £100,000 plus £20,000 VAT in a quarter, but paid £8,000 VAT on your own purchases, your net payment to HMRC is £12,000. VAT is not a cost to your business if your customers are VAT-registered — they simply reclaim it themselves. However, if your customers are consumers or VAT-exempt businesses, adding VAT to your prices effectively makes you more expensive than unregistered competitors.
VAT returns and Making Tax Digital
Most VAT-registered businesses must submit VAT returns quarterly through HMRC's Making Tax Digital (MTD) for VAT system, which requires you to use compatible accounting software (such as Xero, QuickBooks, or FreeAgent) to keep digital VAT records and submit returns. Paper VAT returns are no longer accepted for most businesses. You must submit your return and pay any VAT due within one month and seven days of the end of each VAT period. HMRC operates a VAT default surcharge and points-based penalty system for late submission and late payment. Most SMEs operating under MTD find the process straightforward once they have compatible software set up, but it requires consistent record-keeping throughout the quarter rather than a last-minute scramble.
Voluntary registration and special schemes
You can register for VAT voluntarily before you reach the threshold. This is worth considering if your customers are VAT-registered businesses (who can reclaim VAT), as it allows you to reclaim input VAT on your purchases — potentially improving your cash position. Voluntary registration also signals a level of business activity that some clients associate with credibility. HMRC offers several special VAT schemes that can simplify accounting for SMEs: the Flat Rate Scheme (you pay a fixed percentage of your gross turnover and keep the difference between that and the VAT you charged); the Cash Accounting Scheme (you account for VAT when payment is received rather than when invoiced); and the Annual Accounting Scheme (one VAT return per year with advance payments). Each scheme has eligibility criteria and cash flow trade-offs worth discussing with your accountant.
