2.3 Bad Debt Relief & Partial Exemption Overview

2.3 Bad Debt Relief & Partial Exemption Overview

Quick Summary: Bad Debt Relief enables VAT-registered traders to recover output tax previously declared and paid to HMRC when a customer defaults on payment. Conversely, Partial Exemption rules restrict input tax recovery for businesses that make both taxable and VAT-exempt supplies, allocating input tax via direct attribution and residual calculation methods.

Managing VAT compliance requires handling uncollectible customer balances and ensuring input tax is not inappropriately reclaimed on non-taxable (exempt) commercial activities.

1. Bad Debt Relief (BDR) for Suppliers

When a business sells goods or services on credit, it accounts for output VAT on the invoice date (tax point) and pays this VAT to HMRC on its quarterly return. If the customer subsequently fails to pay, the supplier has suffered a loss including the VAT handed over to HMRC.

Conditions to Reclaim Bad Debt Relief

A supplier can reclaim output tax paid on a bad debt by fulfilling all four statutory conditions:

1. Output VAT Accounted For: The output tax must have already been declared on a previous VAT return and paid to HMRC.
2. Written Off in Accounts: The debt must be formally written off in the trader's accounting records and transferred to a separate refunds for bad debts account.
3. 6 Months Past the Relevant Date: At least 6 calendar months must have elapsed since the later of the date payment was due and payable and the date of supply (NOT the invoice date, unless the two coincide).
4. Time Limit (4 Years 6 Months): Under VAT Notice 700/18 the claim must be made within 4 years and 6 months of the later of the date payment was due and payable and the date of supply.
5. Debt Not Sold or Assigned: The debt must not have been sold, factored or otherwise assigned to a third party, and the goods must not have been supplied at above the customary selling price.

A supplier must not issue a credit note to the customer for a bad debt — the relief is claimed through Box 4, not by cancelling the original supply. Records supporting the claim (a separate refunds for bad debts account, copy invoices, and the calculation) must be kept for 4 years from the date of the claim.

Accounting for Bad Debt Relief

Bad Debt Relief is claimed by adding the VAT element of the uncollected debt to Box 4 (Input Tax) of the VAT Return for the period in which all conditions are satisfied.

Worked Example 1: Bad Debt Relief Claim Date

Meridian Supplies Ltd issued an invoice for £3,000 net + £600 VAT = £3,600 on 15 January 2025. Credit terms state payment is due on 28 February 2025. Meridian declared £600 output VAT in its Q1 2025 return. The customer defaulted.

1. Determine the relevant date: the later of the date of supply (15 January 2025) and the date payment was due and payable (28 February 2025) → 28 February 2025.
2. Calculate 6 Months Elapsed Date: 28 February 2025 + 6 months = 28 August 2025.
3. Earliest Claim Return: Meridian can write the debt off to its refunds for bad debts account and claim £600 BDR in Box 4 of its Q3 2025 return (quarter ending 30 September 2025).
4. Latest Claim Date: 28 February 2025 + 4 years 6 months = 28 August 2029.

⚠️ EXAM TRAP 1: Always count the 6-month period from the later of the payment due date and the date of supply, not the invoice tax point date! If credit terms are 60 days, the 6 months start after those 60 days expire.

⚠️ EXAM TRAP 2: The outside limit is 4 years and 6 months, not 3 years and 6 months. Plenty of older revision material still prints the shorter figure.

2. Customer Obligation to Repay Input Tax (Clawback)

To prevent asymmetry where a customer claims input tax but never pays the supplier, UK VAT law enforces a reciprocal clawback rule:

• If a buyer reclaims input tax on a purchase invoice but has not paid the supplier within 6 months of the payment due date, the buyer must repay that input tax to HMRC.
• Accounting Treatment: The buyer reduces Box 4 (Input Tax) by the unpaid VAT amount (or enters a negative input tax entry) in the return covering the 6-month overdue date.
• Subsequent Payment: If the buyer eventually pays the supplier at a later date, they can re-reclaim the input tax in Box 4.

3. Overview of Partial Exemption

A business is partially exempt if it makes both:

1. Taxable Supplies: Standard-rated (20%), reduced-rated (5%), or zero-rated (0%) goods/services.
2. Exempt Supplies: Goods/services explicitly exempt from VAT under UK law (e.g., financial credit, residential property rents, insurance, education, health services).

The Core Partial Exemption Problem

Input tax directly incurred in making taxable supplies is 100% recoverable. Input tax directly incurred in making exempt supplies is 0% recoverable (unless under de minimis limits).

4. Standard Partial Exemption Calculation & Rounding Rule

Under the standard method, input tax is processed in three steps:

Step 1: Direct Attribution

• Identify Category $T$ (Taxable Input Tax): 100% recoverable.
• Identify Category $E$ (Exempt Input Tax): 0% recoverable (subject to de minimis test).
• Identify Category $R$ (Residual Input Tax): General overheads (rent, electricity, IT software) supporting both activities.

Step 2: Calculate Residual Recovery Percentage

Calculate the proportion of residual input tax ($R$) that can be recovered using the turnover formula: $\text{Taxable Recovery \%} = \left( \frac{\text{Value of Taxable Supplies (excl. VAT)}}{\text{Total Value of Taxable + Exempt Supplies}} \right) \times 100\%$

⚡ THE MANDATORY ROUNDING RULE: The resulting percentage MUST ALWAYS BE ROUNDED UP to the next whole percentage point! For example, 64.1% rounds UP to 65%, 81.02% rounds UP to 82%, and 40.0% stays 40%.

Step 3: Compute Recoverable Residual VAT

$\text{Recoverable Residual VAT} = \text{Residual VAT } (R) \times \text{Rounded Recovery \%}$

5. The De Minimis Limits

Exempt input tax ($E$ plus the exempt portion of $R$) is normally non-recoverable. However, to save small businesses from complex restrictions, HMRC allows exempt input tax to be fully recovered if it is de minimis.

The De Minimis Test

Exempt input tax is treated as de minimis and reclaimed in full if it satisfies BOTH of the following tests:

1. Test 1 (Monetary Limit): Total exempt input tax does not exceed £625 per month on average (£1,875 per quarter, or £7,500 per annual accounting year); AND
2. Test 2 (Percentage Limit): Total exempt input tax does not exceed 50% of total input tax incurred ($T + E + R$).

If BOTH tests pass $\rightarrow$ 100% of input tax ($T + E + R$) is recovered!
If EITHER test fails $\rightarrow$ Exempt input tax cannot be reclaimed at all.

Worked Example 2: Partial Exemption & De Minimis Calculation

Caledonia Properties Ltd is a partially exempt trader. For the quarter ended 30 June 2026, its financial records show:

• Taxable Turnover: £300,000 (excluding VAT)
• Exempt Turnover: £100,000
• Total Turnover: £400,000
• Direct Taxable Input Tax ($T$): £5,000
• Direct Exempt Input Tax ($E$): £1,200
• Residual Overhead Input Tax ($R$): £2,000
• Total Input Tax Incurred ($T + E + R$): £8,200

Calculation Steps:

1. Calculate Taxable Turnover Fraction: $\text{Taxable \%} = \frac{£300,000}{£400,000} \times 100\% = 75.0\%$ Since it is exactly 75.0%, rounded percentage = 75%.
2. Apportion Residual VAT ($R = £2,000$):
   • Taxable Residual VAT: $£2,000 \times 75% = £1,500$
   • Exempt Residual VAT: $£2,000 \times 25% = £500$
3. Calculate Total Exempt Input Tax: $\text{Total Exempt Input Tax} = E + \text{Exempt Residual} = £1,200 + £500 = £1,700$
4. Apply De Minimis Test:
   • Test 1 (Quarterly Limit £1,875): Is £1,700 $\le$ £1,875? YES (Passes).
   • Test 2 (50% Limit): 50% of total input tax (£8,200) = £4,100. Is £1,700 $\le$ £4,100? YES (Passes).
5. Conclusion: Since both de minimis limits are satisfied, Caledonia Properties Ltd can recover ALL £8,200 of input tax in Box 4!
