VAT bad debt relief can help VAT-registered businesses recover VAT already paid to HMRC when customers fail to settle qualifying invoices. For businesses carrying significant overdue receivables, this is not simply a bookkeeping adjustment. Identifying eligible debts can release cash back into the business, improve working capital and prevent legitimate VAT recovery opportunities from being missed.
At Apex Accountants, we help businesses review aged debtor balances, calculate recoverable VAT and ensure claims are supported by the records HMRC expects. Our VAT compliance and planning services can also help businesses integrate bad-debt reviews into their wider VAT processes rather than leaving them until year end.
Under normal invoice accounting, a business can become liable for output VAT before the customer has actually paid the invoice.
Suppose a consultancy raises an invoice for £12,000, including £2,000 VAT. It reports and pays the £2,000 VAT to HMRC through its VAT Return. If the customer subsequently fails to pay, the consultancy has not only lost access to the £10,000 net sales value; it has also handed £2,000 to HMRC on money it has not received.
One unpaid invoice may be manageable. A portfolio of overdue customer balances can create a material drain on working capital.
This is why debtor reviews should not sit solely within credit control. Finance teams should also consider whether old receivables have reached the point where VAT can be recovered.
Businesses operating the Cash Accounting Scheme are generally in a different position because VAT is normally accounted for when payment is actually received, making separate bad-debt relief unnecessary for those transactions.
A customer being late with payment does not automatically entitle the supplier to an immediate VAT refund.
HMRC requires the supplier to have already accounted for and paid the VAT on the supply. The debt must also have been written off in the day-to-day VAT records and transferred to a separate bad debt account.
The debt must remain unpaid for at least six months from the later of the date payment became due and payable and the date of supply. It must not have been paid, sold or factored under a valid legal assignment, and the other applicable conditions must also be satisfied.
Businesses should check the current HMRC rules for relief from VAT on bad debts before submitting a claim, particularly where payment terms have changed, part payments have been made or the debt has been assigned.
This makes the contractual payment date important. Where a business agrees genuine extended credit terms with a customer, that later due date can affect when the six-month period begins.
Businesses therefore need reliable records showing invoice dates, agreed payment terms and subsequent variations rather than relying solely on the age shown in accounting software.
Becoming eligible after six months is only one timing test.
For supplies made after 30 April 1997, HMRC generally requires the claim to be made within four years and six months of the later of the payment due date and the date of supply.
This creates a commercial risk for businesses carrying historic debtor balances.
An invoice may sit on the ledger for several years while staff continue trying to recover the money. Meanwhile, the VAT recovery deadline continues to approach.
Regular reviews can identify qualifying invoices well before that final deadline. For companies with large debtor ledgers, quarterly reviews can be particularly valuable because they combine credit control with potential tax recovery.
Consider a business that supplies services worth £10,000 plus £2,000 VAT and has already reported and paid the VAT to HMRC.
The customer does not pay the £12,000 invoice.
Once at least six months have passed from the later relevant date and all other conditions are satisfied, the business may be able to recover the £2,000 VAT.
The claim is made by including the recoverable VAT in Box 4 of the VAT Return covering the date on which the business becomes entitled to the relief.
The commercial distinction is important: HMRC is not reimbursing the £10,000 commercial loss. The business is recovering VAT it previously paid on consideration it has not received.
For a company carrying several high-value unpaid invoices, those VAT recoveries can make a meaningful difference to short-term liquidity.
Part payments need to be reconciled before calculating the claim.
HMRC limits relief to the VAT attributable to the amount that remains unpaid. If customers have made payments against several invoices, specific payment-allocation rules can also become relevant.
For example, if £3,000 has been paid against a £12,000 standard-rated invoice, £9,000 remains outstanding. The VAT contained within that unpaid £9,000 is £1,500.
Subject to the normal conditions, the VAT recovery would therefore be £1,500 rather than the original £2,000.
This is why businesses should not calculate claims using only the headline aged-debtor balance. Individual receipts need to be matched to the correct invoices before the VAT adjustment is made.
VAT recovery is only one part of dealing with an irrecoverable debtor.
Businesses searching for the bad debt write off double entry should avoid assuming that one journal entry applies in every case. The bookkeeping treatment depends on whether an impairment has already been recognised, how the debtor is currently recorded and how the accounting software processes the VAT adjustment.
Using the earlier £12,000 invoice, the customer balance ultimately needs to be removed from trade receivables when it is written off. If £2,000 of VAT is recoverable from HMRC, the remaining £10,000 represents the net commercial loss, subject to any impairment already recognised.
Where an allowance for impairment already exists, part or all of that loss may already have been reflected in the accounts.
A bad debt provision also needs to be distinguished from the specific VAT write-off. HMRC requires the qualifying VAT debt itself to be written off and transferred to a separate bad debt account before relief can be claimed. For Corporation Tax purposes, correctly recognised accounting impairment losses can generally follow the loan relationship rules, while specific restrictions can apply.
Businesses that need tighter control over debtor ledgers, payment allocation and write-offs can use Apex’s outsourced bookkeeping services to keep the accounting records aligned with VAT reporting.
The Corporation Tax position is separate from the VAT adjustment. For companies, impairment losses on trade debts generally fall within the loan relationship rules, and correctly recognised losses may be allowable, although restrictions can apply to connected-company debts.
VAT bad debt relief follows different conditions. The VAT must already have been accounted for and paid, the debt must have remained unpaid for six months from the later of the due date and supply date, and the debt must be written off to a separate bad debt account.
A business should therefore assess the accounting treatment, VAT position and Corporation Tax computation separately. An impairment recognised at year end does not automatically support a VAT claim if the six-month condition has not yet been met.
Our Corporation Tax services can help companies coordinate the treatment of impaired trade debts with their wider Corporation Tax position while keeping the VAT adjustment distinct.
HMRC requires businesses to retain sufficient evidence for each claim.
Good records are essential because HMRC may check whether the VAT claimed is supported by the underlying invoices, payment history and accounting entries. Its guidance on keeping VAT records explains the records VAT-registered businesses must retain, including sales invoices, VAT adjustments and digital VAT records
This includes copies of the relevant VAT invoices and a separate bad debt account showing information such as the amount written off, VAT being claimed, VAT period of the claim, VAT originally charged, the period in which it was originally accounted for, payments received, customer details and invoice references.
Claim-specific records must be retained for four years from the date of the claim. HMRC notes that this does not replace the wider standard VAT record-retention requirement.
The VAT bad debt relief manual provides more detailed internal HMRC guidance on the administration of the regime. However, businesses should use HMRC’s public VAT Notice 700/18 as their principal operational guidance rather than treating the internal manual as a substitute for the published rules.
Strong records become particularly important where payment terms have changed, part payments have been made or several invoices are outstanding for the same customer.
Recovering VAT does not cancel the customer’s commercial liability.
If the customer later pays all or part of a debt for which relief has already been claimed, the VAT element relating to that payment must be repaid to HMRC.
HMRC requires the relevant amount to be included in Box 1 of the VAT Return for the period in which the later payment is received.
For example, if £6,000 is later recovered against a standard-rated debt, £1,000 represents VAT.
That VAT would need to be brought back into the VAT accounting.
Businesses should therefore flag every debtor balance on which relief has been claimed. Without that control, a later payment can be posted as a simple debtor recovery while the required VAT adjustment is missed.
Bad-debt VAT rules do not operate only in favour of businesses.
If a business has reclaimed input VAT on a supplier invoice but subsequently fails to pay the supplier, it may have to repay the relevant input VAT to HMRC once six months have passed from the relevant date.
For later supplies covered by the current rules, the relevant date is the date of supply or, if later, the payment due date.
If the supplier is later paid, the corresponding input VAT can generally be reclaimed again, subject to the normal rules.
This is why a proper VAT review should examine both sides of the balance sheet.
A company could identify a valuable recovery from old customer debts while simultaneously having an obligation to adjust VAT on supplier bills it has left unpaid.
Reviewing aged debtors without reviewing aged creditors can therefore give management an incomplete picture of the company’s true VAT position.
Invoice finance can make the relief more complicated because the legal ownership of the customer debt matters.
HMRC states that relief is not available while a debt has been factored under an absolute assignment. Where an agreement allows the debt to be reassigned to the original trader, relief may become available after that reassignment takes place.
Businesses using factoring should therefore check the actual terms of their agreement rather than assuming that an unpaid customer automatically creates a VAT recovery opportunity.
This is especially relevant where invoice finance is used across a large debtor book and different arrangements apply to different customers.
An unpaid invoice should not simply be cleared by issuing a credit note.
HMRC states that a credit note may be issued where there is a genuine mistake, overcharge or agreed reduction in the value of the supply. It should not be issued merely because the customer has failed to pay.
The distinction is commercially important.
A genuine bad debt remains legally due from the customer even though collection may be doubtful. A credit note, by contrast, reduces the amount that the customer owes.
Using credit notes merely to remove overdue balances can therefore misstate revenue, VAT and the customer account.
The strongest process is to identify qualifying debts as part of routine VAT preparation rather than conducting an occasional clean-up exercise.
A finance team should be able to identify invoices approaching or passing the six-month point, part-paid debts, claims nearing the final deadline, debts that have been factored, amounts previously relieved but subsequently recovered and supplier balances that may require input VAT adjustment.
This approach turns an ageing debtor report into a cash-flow control.
It also reduces the risk of discovering missed claims several years later when documentation is harder to locate and staff responsible for the original transaction may no longer be available.
For businesses with large sales ledgers, integrating these reviews into monthly or quarterly financial reporting can provide management with a clearer picture of how much VAT remains tied up in overdue customer balances.
Unpaid invoices affect more than credit control. They can influence cash flow, VAT Returns, bookkeeping records, year-end accounts and Corporation Tax at the same time.
Apex Accountants can review aged receivables to identify debts that may qualify, confirm relevant dates, reconcile part payments and calculate the potential VAT recovery. We can also review aged supplier balances to identify input VAT adjustments that may have been overlooked.
Where relief has already been claimed, we can help establish controls for monitoring subsequent customer payments so the corresponding VAT is brought back into the correct return.
If HMRC queries the treatment, our HMRC investigation support can assist with reviewing the records, preparing supporting information and managing correspondence.
For a business carrying substantial overdue receivables, the key commercial question is simple: how much VAT has already been paid to HMRC on income that has still not been collected?
Finding that answer before the claim deadline can release cash and strengthen control over future VAT periods.
For most current supplies, the debt must remain unpaid for at least six months from the later of when payment became due and payable or the date of supply. The remaining conditions must also be satisfied before a claim can be made.
The VAT being recovered is entered in Box 4 of the VAT Return covering the date on which the business becomes entitled to make the claim.
Yes. Where a qualifying invoice has been partly paid, relief is restricted to the VAT attributable to the amount that remains unpaid.
No. Formal insolvency is not a general requirement under the current rules. The key tests include the six-month unpaid period, the accounting write-off and the other qualifying conditions set out by HMRC.
For supplies made after 30 April 1997, a claim must generally be made within four years and six months of the later of the payment due date and the date of supply.
If payment is subsequently received after relief has been claimed, the VAT element of that payment must generally be repaid to HMRC and included in Box 1 of the relevant VAT Return.
Yes. Apex Accountants can review historic aged receivables, identify invoices that may still fall within HMRC’s time limits, calculate potential recoveries and check that the underlying bookkeeping records support the adjustment before it is included in a VAT return.
