The VAT cash accounting scheme lets you account for VAT on the basis of when cash is received or paid rather than when invoices are raised or received. This can improve cash flow for many early-stage founders and e-commerce sellers in the UK.
However, the scheme has important restrictions on turnover, input tax recovery and suitability that must be considered before opting in. Rules and limits change regularly, so always check the latest guidance on GOV.UK or with HMRC before making a decision.
How the VAT Cash Accounting Scheme Works
Under the cash accounting scheme you only declare output VAT to HMRC when your customers actually pay you. Similarly, you reclaim input VAT on purchases only when you have paid your suppliers. This differs from the standard method where VAT is accounted for on the date an invoice is issued or received, regardless of payment.
To use the scheme you must apply to HMRC and keep records that clearly show payment dates for both sales and purchases. You issue normal VAT invoices to customers but only include the related VAT in your VAT return once payment arrives in your bank account. The same principle applies in reverse for reclaiming VAT on expenses.
Most standard-rated, reduced-rated and zero-rated transactions can be included. Certain transactions such as hire purchase and some exempt supplies are excluded. You must use the scheme for all your VAT-registered business activities once you have joined.
Turnover Limits and Eligibility
Eligibility for the cash accounting scheme is linked to your VAT-taxable turnover. The limits are subject to regular review so you must check the current figures on GOV.UK before applying or renewing. Generally the scheme is designed for smaller businesses whose turnover falls below a set threshold.
If your turnover later exceeds the exit threshold you will usually need to leave the scheme. There is sometimes a grace period if the increase is temporary. You cannot join the scheme if you have been convicted of certain VAT offences or are currently using another special accounting scheme that is incompatible.
For startups and e-commerce sellers this means the scheme is most relevant in the early years while turnover remains modest. Rapidly scaling businesses may find they outgrow the limits sooner than expected.
Recovery of Input Tax
One of the most important features is that you can only reclaim VAT on purchases once you have paid the supplier. If you receive an invoice but have not yet settled it, the related input tax cannot be included on that VAT return.
This creates a timing difference compared with standard accounting. For businesses that buy on credit and pay later, the delay in reclaiming input VAT can affect cash flow negatively. Conversely, if you pay suppliers promptly you may be able to recover input tax faster than under normal rules.
Keep clear evidence of payment dates. Bank statements, payment confirmations and supplier receipts are usually sufficient. You must not claim input tax before the payment has left your account. Accurate record-keeping is therefore essential and forms a practical part of day-to-day administration for any VAT-registered founder.
Advantages for Early-Stage Founders
The main benefit is improved cash flow. By only paying HMRC the net VAT once customers have paid you, the scheme can help when customers are slow to settle invoices. This is common for many new e-commerce sellers who rely on marketplace platforms with delayed payout cycles.
It can also simplify bookkeeping for some businesses because the focus is on actual bank movements rather than invoice dates. This may reduce the chance of declaring VAT on sales that later become bad debts. You can usually write off the VAT on a bad debt once you are satisfied the customer will not pay.
For UK founders operating on tight budgets in the first 12–24 months, deferring the payment of output VAT until money is in the bank can free up working capital that would otherwise be tied up with HMRC.
Disadvantages and Potential Drawbacks
The scheme is not always advantageous. If you regularly buy goods on credit and pay suppliers after 30, 60 or 90 days you may have to wait longer to reclaim input VAT. This can create a cash-flow disadvantage that outweighs any benefit on the sales side.
Administrative effort can also increase. You must track every payment against the related invoice, which requires disciplined record-keeping. Mistakes in matching payments can lead to incorrect VAT returns and potential penalties.
Another limitation is that the scheme cannot be used for certain types of transaction. If your e-commerce business sells a mix of standard-rated and exempt items you will need to separate transactions carefully. Growing businesses that expect to exceed the turnover limits within a short period may find the short-term benefit is outweighed by the need to switch accounting methods later.
Suitability for Startups and E-commerce Sellers
The cash accounting scheme often suits startups that invoice other businesses and experience payment delays. Sole traders and newly incorporated limited companies selling on platforms such as Shopify, Amazon or Etsy may benefit if their suppliers are paid immediately or on short terms.
It is usually less suitable for businesses that make mostly zero-rated or exempt supplies, or those that buy large volumes of stock on extended credit. Retailers selling directly to consumers for immediate payment may see little advantage because customers typically pay at the point of sale.
Before deciding, prepare a simple cash-flow forecast covering the next six to twelve months. Compare the timing of expected customer receipts against supplier payments and estimate the net VAT position under both standard and cash accounting methods. This practical exercise helps founders see whether the scheme genuinely improves liquidity for their specific business model.
Practical Steps to Apply and Use the Scheme
First confirm your current turnover is within the permitted limit by checking the latest guidance on GOV.UK. Then complete the appropriate notification form online or by post. HMRC usually confirms acceptance within a few weeks.
Once approved, update your accounting software or spreadsheets to record VAT based on payment dates. Mark each sales and purchase invoice with the date it is paid. Reconcile your VAT return to bank statements rather than the sales and purchase day books.
Review your position every quarter before submitting the return. If you realise you have exceeded the limits or no longer wish to use the scheme you must notify HMRC promptly. Keep all supporting payment evidence for at least six years in case of any enquiry.

Frequently asked questions
Can I reclaim VAT on unpaid supplier invoices under the cash accounting scheme?
No. You can only reclaim input VAT once you have actually paid the supplier. This is a core rule of the scheme and differs from standard VAT accounting where the tax point is usually the invoice date.
What happens if my turnover exceeds the limit while using the scheme?
You will generally need to leave the scheme. Check the current exit threshold and any grace period on GOV.UK. You must then switch to standard VAT accounting from the appropriate date.
Is the cash accounting scheme compulsory for small businesses?
No. It is entirely optional. You must weigh the cash-flow benefits against any disadvantages for your particular sales and purchase patterns before deciding whether to join.
Does using the cash accounting scheme affect my ability to claim bad debt relief?
The scheme can make bad debt relief simpler because you only account for the VAT once payment has been received. If a customer never pays you can usually adjust the VAT once you are satisfied the debt will not be settled.
Can I use the scheme if I sell on Amazon or eBay?
Yes, provided your total VAT-taxable turnover is within the current limits and you meet all other eligibility rules. You will still need to match VAT to the actual payment dates shown in your marketplace payout reports.
