What Is VAT Cash Flow Planning?
VAT cash flow planning means setting aside VAT collected from customers in a separate account so it is available when the quarterly return is due. VAT collected belongs to HMRC — treating it as available cash is one of the most common causes of SME tax crises.
The Formula
VAT Liability = Output VAT Collected − Input VAT Paid
Worked Example — UK SME
A UK business: quarter sales (inc 20% VAT) £57,600. Output VAT = £9,600. Input VAT on purchases = £2,400. Net VAT liability = £7,200 due to HMRC at quarter end.
UK Benchmark
📊 UK businesses on standard VAT accounting pay within one month and seven days of quarter end. Setting aside VAT weekly eliminates the quarterly cash shock that causes crises for thousands of UK SMEs each year.
Common Questions
What is the VAT Flat Rate Scheme?
Businesses pay a fixed percentage of gross turnover as VAT. Simplifies administration and can benefit businesses with low input VAT. Available for businesses with taxable turnover below £150,000.
What happens if I can’t pay my VAT bill?
Contact HMRC’s Business Payment Support Service before the due date. HMRC will consider a Time to Pay arrangement. Always file on time even if you can’t pay immediately.
How do I set up VAT cash flow planning?
Open a separate savings account. Transfer 16–18% of net revenue into it each week. This eliminates the quarterly VAT shock and covers corporation tax provisions simultaneously.
