UK VAT Schemes Compared: Standard, Flat Rate, Cash and Annual
HMRC offers four main VAT accounting schemes: standard, flat rate, cash accounting and annual accounting. The right scheme depends on turnover, cash flow and the proportion of zero-rated or exempt sales.
Quick answers
What VAT schemes are available in the UK?
HMRC offers four main schemes: standard accounting (invoice basis, quarterly returns), the Flat Rate Scheme (fixed percentage of gross turnover), cash accounting (VAT due when paid, not invoiced) and annual accounting (one return a year with interim payments). Most small businesses can mix cash and annual together.
Should I join the Flat Rate Scheme?
FRS suits service businesses with low input VAT and turnover under £150,000. You pay a fixed percentage (e.g. 14.5% for IT consultants) of gross turnover instead of calculating input vs output VAT. Limited-cost traders pay 16.5% — usually worse than standard accounting, so check first.
What's the difference between cash and accrual VAT accounting?
Standard (accrual) accounting requires VAT to be paid based on invoice dates, even if the customer hasn't paid. Cash accounting defers VAT until the customer actually pays you, which protects cash flow and bad debts. Eligible if VAT-taxable turnover is £1.35m or less.
Why the choice matters
Picking the wrong VAT scheme can cost a small business thousands a year in unnecessary VAT or admin time. The four schemes below are the most common in the UK.
Standard VAT accounting
- Account for VAT on the invoice date (output VAT) and the invoice date of supplier invoices (input VAT)
- File quarterly VAT returns under MTD
- Reclaim full input VAT on purchases
- Best for: businesses with significant input VAT, especially capital purchases or large recoverable expenses
Flat Rate Scheme (FRS)
- Pay a fixed percentage of gross turnover (including VAT) instead of calculating output minus input VAT
- Different rates by trade sector — e.g. 14.5% IT consultants, 12% management consultants, 9.5% printing
- "Limited cost trader" rate of 16.5% applies if goods cost less than 2% of turnover (or less than £1,000 a year)
- Eligible if VAT-exclusive turnover ≤ £150,000; must leave when total income exceeds £230,000
- Can still reclaim VAT on capital assets over £2,000
- Best for: service businesses with low input VAT (designers, consultants, IT contractors)
Cash accounting
- Account for VAT on the date of payment rather than the invoice date
- Major cash-flow benefit if customers pay slowly — you don't pay VAT until your customer pays you
- Eligible if VAT-taxable turnover is ≤ £1.35m; must leave at £1.6m
- Can't reclaim input VAT until you've paid the supplier
- Not compatible with flat rate (which has its own cash-based version)
- Best for: businesses with extended payment terms or bad-debt risk
Annual accounting
- File one VAT return per year instead of four
- Make 9 monthly or 3 quarterly interim payments based on the previous year's liability, then a balancing payment with the return
- Eligible if VAT-taxable turnover ≤ £1.35m; leave at £1.6m
- Reduces admin but doesn't change the amount of VAT due
- Best for: stable, predictable businesses that want less paperwork
Quick comparison
| Scheme | Best for | Turnover limit | Cash-flow benefit |
|---|---|---|---|
| Standard | High input VAT | None | Neutral |
| Flat Rate | Service businesses, low costs | £150k join, £230k leave | Possible if FRS % is low |
| Cash | Slow-paying customers | £1.35m join, £1.6m leave | Yes |
| Annual | Steady businesses, less admin | £1.35m join, £1.6m leave | Smooths cash flow |
How to switch
Apply to HMRC for FRS, cash or annual accounting (forms VAT600 FRS, VAT600 AA). Most changes take effect from the next VAT period. You can usually combine cash accounting with annual accounting but not with flat rate.
