Comparing VAT Special Schemes and Choosing the Best One

Updated 11 October 2026 · Fact-checked

The cash accounting, annual accounting and flat rate schemes simplify VAT for smaller businesses. Cash accounting ties VAT to payments, annual accounting spreads payments through the year with one return, and flat rate applies a fixed percentage to VAT-inclusive turnover. To choose, check eligibility, then compare VAT cost, cash flow and admin.

Understand Comparing Special Schemes and Choosing Between Them

A special scheme changes how a business accounts for VAT. It does not change the VAT rate, which is 20% for standard-rated supplies. It changes when VAT is paid, how often returns are filed, or how the amount is calculated.

The cash accounting scheme changes timing. Output tax is due when you receive cash from customers. Input tax is recoverable when you pay suppliers. If a customer never pays, you never account for the output tax, so bad debt relief is automatic. The downside is that input tax on purchases is delayed until you pay for them.

The annual accounting scheme changes the filing pattern. You make interim payments during the year and file one return. This cuts admin. It helps cash flow when profits are growing, because payments are based on last year's VAT. It can hurt if the business is shrinking or expects a repayment, because you cannot claim repayments early.

The flat rate scheme changes the calculation. You do not compute output tax less input tax. You apply a flat rate percentage, set by trade sector and given in the exam, to VAT-inclusive turnover. You generally cannot recover input tax, apart from some capital purchases. This saves record keeping. It only saves tax if the flat rate percentage is lower than the true net VAT.

An exam answer to an advice question is a short comparison. State the entry conditions, test whether the client qualifies, quantify the effect where you can, then give a clear recommendation with reasons.

Key rules to remember

Cash accounting: entry and exit: Join if expected taxable turnover ≤ £1,350,000; must leave if turnover exceeds £1,600,000; Output tax is accounted for on receipt, input tax on payment. Bad debt relief is automatic. Learn these limits as the ACCA rules; they are not in the rates table.
Annual accounting: entry and exit: Join if expected taxable turnover ≤ £1,350,000; must leave if turnover exceeds £1,600,000; One return a year, due within two months of the year end. You must be up to date with VAT returns to join.
Annual accounting: payments: Nine monthly payments of 10% of prior year VAT liability (months 4 to 12); balancing payment = actual liability − interim payments; The balancing payment is due with the annual return, within two months of the year end. An alternative is three quarterly payments of 25%.
Flat rate scheme: entry and exit: Join if expected taxable turnover (excluding VAT) ≤ £150,000; must leave if VAT-inclusive turnover exceeds £230,000; Know the limits as the ACCA rules. They are not in the rates table.
Flat rate scheme: VAT payable: VAT payable = flat rate % × VAT-inclusive turnover; Turnover includes standard-rated, zero-rated and exempt supplies, all at their VAT-inclusive value. Input tax is generally not recovered, except on capital expenditure over £2,000 including VAT. A 1% reduction in the flat rate applies in the first year of VAT registration.
VAT registration limits (for context): Registration £90,000; deregistration £88,000; standard rate 20%; These come from the ACCA rates table. Schemes apply only to VAT-registered traders.

How to solve Comparing Special Schemes and Choosing Between Them questions

Use this method for any question asking whether a business should join a scheme, or which scheme suits it.

1Read the facts and list the client's turnover, mix of supplies (standard, zero-rated, exempt), purchases, credit terms, bad debts and cash flow position.
2Check eligibility for each scheme against the turnover limits. Use expected taxable turnover for entry. State the limit and the result in one line.
3Work out what the client pays under normal VAT accounting: output tax less recoverable input tax.
4If the flat rate scheme is in play, calculate flat rate % × VAT-inclusive turnover and compare it with the normal figure. Include any capital purchase input tax that could still be reclaimed.
5If cash or annual accounting is in play, explain the timing effect: when output tax is due, when input tax is recovered, and the instalment or balancing amounts.
6Compare each scheme on VAT cost, cash flow and admin. Note any drawback, such as no early repayments or lost input tax.
7Give a clear recommendation tied to the client's facts, and mention the exit limits so the client knows when the scheme must stop.

Quickest way: Eligibility, cost, cash flow in three lines

When to use it: Use this for Section C advice questions and for OT case questions that ask which scheme is most suitable.

Eligibility: compare expected taxable turnover with £1,350,000 (cash and annual) or £150,000 excluding VAT (flat rate).
Cost: flat rate payment against normal output tax less input tax. A low-input, standard-rated business gains. A business with heavy purchases or zero-rated sales usually loses.
Match the scheme to the problem. Slow-paying customers or bad debts point to cash accounting. Admin burden or a wish to smooth payments points to annual accounting. Simple records and low input tax point to flat rate.
Write the recommendation and one disadvantage in two or three sentences.

Common mistakes in Comparing Special Schemes and Choosing Between Them

Applying the flat rate percentage to turnover excluding VAT.
Students are used to working with net figures in VAT calculations.
Fix: Gross up first. Standard-rated net sales × 1.2, then multiply by the flat rate percentage. Include zero-rated and exempt sales at face value.
Deducting input tax under the flat rate scheme.
Students carry over the normal VAT computation by habit.
Fix: Flat rate payable is just the percentage times VAT-inclusive turnover. The only usual exception is capital expenditure over £2,000 including VAT.
Mixing up the entry limits, using £150,000 for all three schemes or £1,350,000 for all three.
The limits look similar and are easy to blur under pressure.
Fix: Remember: cash and annual accounting share £1,350,000 to join and £1,600,000 to leave. Flat rate is £150,000 to join, excluding VAT, and £230,000 to leave, including VAT.
Recommending cash accounting without noting that input tax recovery is delayed until suppliers are paid.
Students focus on the bad debt benefit and forget the other side.
Fix: Give both effects. Output tax is deferred until cash is received, and input tax is deferred until payment. The net effect depends on credit given and credit taken.
Calculating annual accounting instalments as 10% of the current year's VAT.
The word annual suggests the current year is the base.
Fix: Interim payments are 10% of the previous year's liability. The balancing payment uses the actual current year figure.
Giving advice with no recommendation, only a list of rules.
Students run out of time or lack the confidence to commit.
Fix: Finish with a clear sentence such as: I recommend the client joins the flat rate scheme because it saves £X and cuts record keeping.

Worked examples

Example 1

Priya runs a consultancy. Her expected taxable turnover for the next year is £120,000 excluding VAT, all standard-rated. Her purchases will be £50,000 excluding VAT, all standard-rated, with no capital purchases. The applicable flat rate is 9%. Advise whether she should join the flat rate scheme, ignoring the first-year reduction.

Show the solution

Eligibility: expected taxable turnover of £120,000 is within the £150,000 limit, so she can join.
Normal VAT: output tax is £120,000 × 20% = £24,000.
Input tax is £50,000 × 20% = £10,000, so VAT payable is £24,000 − £10,000 = £14,000.
Flat rate: VAT-inclusive turnover is £120,000 × 1.2 = £144,000.
VAT payable is £144,000 × 9% = £12,960.
Saving is £14,000 − £12,960 = £1,040 a year, plus simpler records.

Answer: Priya is eligible and should join. The flat rate scheme costs £12,960 against £14,000 under normal accounting, saving £1,040 and reducing record keeping. She must leave the scheme if her VAT-inclusive turnover exceeds £230,000. If she is in her first year of VAT registration, the rate is reduced by 1%, which increases the saving.

Example 2

Omar's wholesale business has expected taxable turnover of £800,000 a year. Customers take about 60 days to pay and there are occasional bad debts. Last year's VAT liability was £48,000 and this year's actual liability is £54,000. Advise on cash accounting and annual accounting, and calculate his annual accounting payments for this year.

Show the solution

Eligibility: £800,000 is below £1,350,000, so both schemes are available. The flat rate scheme is not, because turnover exceeds £150,000.
Cash accounting: output tax is due only when customers pay. This helps with 60-day credit and bad debts, as VAT on unpaid invoices is never paid and relief is automatic. Input tax is recovered only when Omar pays suppliers.
Annual accounting interim payments: 10% × £48,000 = £4,800 a month for nine months (months 4 to 12).
Total interim payments are 9 × £4,800 = £43,200.
Balancing payment: £54,000 − £43,200 = £10,800, due with the annual return within two months of the year end.
Compare: annual accounting reduces filing to one return and sets known payments, but it does not fix the late-payment problem. Cash accounting addresses it directly.

Answer: Omar can use cash or annual accounting but not the flat rate scheme. Under annual accounting he pays £4,800 a month for nine months (£43,200) and a balancing payment of £10,800. Because slow-paying customers and bad debts are his main problem, I recommend cash accounting. It links VAT to cash received and gives automatic bad debt relief. He should note that input tax recovery is delayed until suppliers are paid, and he must leave if turnover exceeds £1,600,000.

Exam tips

In advice questions, write eligibility first with the exact limit and the client's figure. It is an easy mark and shows structure.
Always show the flat rate working: gross turnover, percentage, and a comparison with the normal VAT figure. Marks go to the working even if the final comparison is off.
Match the scheme to the stated problem in the scenario: bad debts, slow payers, admin burden, heavy purchases or zero-rated sales. The examiner builds the facts to point one way.
In OT questions, read for traps such as turnover quoted including VAT, or a capital purchase that is still reclaimable under flat rate. Answers are all or nothing.
Always state one disadvantage of the scheme you recommend. Balanced advice earns more than one-sided advice.

Comparing Special Schemes and Choosing Between Them: frequently asked questions

What is the difference between the cash accounting and annual accounting schemes?

Cash accounting changes when VAT is accounted for: output tax on receipt, input tax on payment. Annual accounting changes how often you file: nine interim payments based on last year's liability and one annual return. They solve different problems, and both have the same turnover limits.

Which VAT scheme is best for a small business in the ACCA exam?

There is no single best scheme. The flat rate scheme suits a small, low-input business whose flat rate gives less VAT than the normal method. Cash accounting suits one with slow-paying customers or bad debts. Annual accounting suits one that wants fewer returns and smooth payments.

Why can the flat rate scheme cost more than normal VAT?

Because you cannot generally recover input tax, and the percentage applies to VAT-inclusive turnover. If the business has high purchases or makes zero-rated sales, normal VAT accounting often gives a lower liability. Always calculate both before advising.

Do I need to memorise the scheme limits for TX-UK?

Yes. The tax rates table gives the registration and deregistration limits, but the scheme entry and exit limits are not in it, so you should know them. Learn £1,350,000 and £1,600,000 for cash and annual accounting, and £150,000 and £230,000 for flat rate.
