VAT Annual Accounting Scheme: nine payments of 10%, then a balancing payment, worked for a client

A client with a steady VAT bill asks whether they could stop filing four returns a year. The VAT Annual Accounting Scheme means one return a year and advance payments in between. The question for the practice is whether the cash timing suits the client. This guide works the payments for one example client.

What the source says

GOV.UK says a business can join if its estimated VAT taxable turnover is £1.35 million or less in the next 12 months. A business cannot use the scheme if it left it in the last 12 months, is part of a VAT registered division or group of companies, is not up to date with VAT returns or payments, or is insolvent. It must leave if it is no longer eligible, including when taxable turnover is above £1.6 million at the end of the annual accounting year, or is likely to be.

The advance payments are based on the last return, or an estimate for a business new to VAT. Each is either 10% of the estimated VAT bill (monthly, due at the end of months 4, 5, 6, 7, 8, 9, 10, 11 and 12) or 25% (quarterly, due at the end of months 4, 7 and 10). The balancing payment is the difference between the advance payments and the bill on the return. For a 12-month year it is due within 2 months of month 12, and so is the return.

The sums: a client with an £8,400 estimate

Take a client whose last return gave a VAT bill of £8,400, so £8,400 is the estimate for the new year.

Check: £840 x 9 = £7,560 (£840 x 10 = £8,400, less £840). £2,100 x 3 = £6,300. Monthly payments cover 90% of the estimate, quarterly payments 75%.

What the balancing payment looks like

The estimate is only a guide, so the real bill decides the final payment.

Check: £9,600 - £7,560 = £2,040; £9,600 - £6,300 = £3,300; £8,400 - £7,560 = £840; £8,400 - £6,300 = £2,100; £7,560 - £7,200 = £360; £7,200 - £6,300 = £900. The GOV.UK overview says an overpayment is a refund.

Why it matters to the client

• Growth catches clients out. If sales rise, the estimate understates the bill and the balancing payment grows, as in the £9,600 row. A client who has spent the cash will feel it. Keep a running figure of the bill so far.
• The months are counted from the year start. A year starting 1 January means monthly payments end April to December, and the return and balancing payment are due by the end of the following February. Confirm the client's own accounting year with HMRC's confirmation; I did not read how the year is set.
• Leaving is allowed, rejoining is not for 12 months. GOV.UK says a business can leave at any time but cannot rejoin for 12 months, so a client who is unsure should think before joining.
• Compare with other schemes. Clients using a different scheme may find it better, for example the VAT flat rate scheme, and a client whose customers do not pay may want bad debt relief. Check also where the registration threshold sits for a growing client.

What I did not read

I did not read the GOV.UK page on how to apply, the VAT Notice for the scheme, or what happens with a part-year or a short first period beyond the lines quoted. The sums assume a 12-month year, the standard payment percentages and an estimate that uses the last return. I have not checked whether the figures here match HMRC's own payment schedule for a particular client.
