Bad Debt vs Doubtful Debt: What's the Difference and Why It Matters
Your client owes you $4,500. It's 75 days overdue. They replied once to say "payment coming soon" — and then went quiet again. Is this a bad debt or a doubtful debt? The answer changes your journal entry, your balance sheet, and potentially your tax position. Getting it wrong doesn't just affect your books — it affects the decisions you make about your business.
These two terms are often used interchangeably, even by experienced bookkeepers. They shouldn't be. They describe two different stages of the same problem, and accounting treats them in two completely different ways.
The One-Sentence Answer
If you're not yet clear on where receivables fit in your accounts, our guide on assets, liabilities and capital explains why money owed to you is classified as an asset — and why overstating that asset creates problems.
Doubtful Debt: What It Is and How to Treat It
A doubtful debt is an outstanding invoice where there is genuine uncertainty about whether payment will arrive. The client might still pay — but the evidence suggests the risk is elevated enough to warrant caution in your accounts.
Common reasons a debt becomes doubtful:
- The invoice is more than 60 days past due with only partial contact
- The client has mentioned cash flow difficulties
- A payment promise was broken once already
- The client's industry or business is visibly struggling
- Multiple small partial payments followed by silence
How Doubtful Debts Are Recorded
Doubtful debts are handled through a provision for bad debts (also called an allowance for doubtful accounts). Instead of writing off a specific invoice, you create a general estimate of expected losses and reduce your net receivables on the balance sheet by that amount.
| Account | Debit ($) | Credit ($) | Effect |
|---|---|---|---|
| Bad Debt Expense | 1,885 | — | Reduces profit on P&L |
| Provision for Bad Debts | — | 1,885 | Contra-asset reduces net receivables on Balance Sheet |
The key point: the individual invoices remain on your books. You haven't written any specific one off — you've simply acknowledged that statistically, some percentage won't be collected. The receivables figure on your balance sheet is now honest rather than optimistic.
For the full step-by-step guide to calculating and recording the provision — including the aging schedule method — see our article on how to calculate and record provision for bad debts.
Bad Debt: What It Is and How to Treat It
A bad debt is an invoice — or part of one — that you have confirmed will not be collected. The uncertainty is gone. You've exhausted reasonable collection attempts, or you have clear evidence (bankruptcy notice, disconnected business, legal judgment in their favour) that payment won't come.
Common confirmation that a debt is bad:
- Client has declared bankruptcy with no assets available to creditors
- The business has been dissolved or struck off
- A court judgment went in the client's favour
- The debt has been outstanding for more than 12 months with zero contact
- A professional debt collector has confirmed it's unrecoverable
How Bad Debts Are Recorded
A bad debt is written off by removing the specific invoice from your accounts receivable. If a provision already exists, the write-off uses the provision rather than creating a new expense:
| Scenario | Debit | Credit |
|---|---|---|
| Write-off WITH existing provision | Provision for Bad Debts $500 | Accounts Receivable $500 |
| Write-off WITHOUT existing provision | Bad Debt Expense $500 | Accounts Receivable $500 |
When a provision already exists, the write-off does not hit the Profit & Loss again — the expense was already recognized when the provision was created. Using the provision is accounting's way of ensuring you don't charge the same loss twice. This connects directly to how the accounting equation stays balanced throughout the process.
Side-by-Side Comparison
| Criteria | Doubtful Debt | Bad Debt |
|---|---|---|
| Certainty of loss | Uncertain — might still be paid | Confirmed — will not be paid |
| Accounting method | Provision (allowance method) | Write-off (direct or via provision) |
| Invoice on books? | Yes — stays in gross receivables | No — removed from accounts receivable |
| Balance sheet impact | Reduces net receivables via contra-asset | Reduces gross receivables directly |
| P&L impact | Bad debt expense when provision created | Absorbed by provision (no double charge) |
| GAAP requirement | Required for most businesses (accrual) | Required when confirmed uncollectable |
| Can be reversed? | Yes — reduce provision if client pays | Yes — reinstate debt, then record cash |
| Example timing | 60–90 days overdue, some contact | Bankruptcy confirmed, 12 months no contact |
The Journey: How a Doubtful Debt Becomes a Bad Debt
These two things aren't separate categories you choose between. They're stages in the same deterioration of a receivable. Understanding the progression helps you take the right action at the right time.
The transition from doubtful to bad is a judgment call — and it needs to be documented. Tax authorities and auditors expect you to show reasonable evidence before writing off a debt. "I just had a feeling" isn't sufficient. "Client filed Chapter 7 on March 12th and we received the bankruptcy notice" is.
In October, Emma runs her aging schedule and spots a $2,800 invoice from a marketing agency that's 70 days overdue. They've replied twice — both times vaguely. She creates a provision of $420 (15% at 61–90 days stage). The invoice stays in her receivables, but net receivables drop by $420. In December, Emma learns the agency has gone into administration. All assets are frozen. She writes off the full $2,800 against her existing provision — a partial amount against the provision and the remainder as a new bad debt expense. The invoice is gone from her books. Her December P&L takes a hit, but her October accounts already absorbed part of it. The provision did its job.
How the Provision and the Write-Off Work Together
The provision and the write-off aren't alternatives — they're partners. Here's the complete cycle in one picture:
Recording a bad debt write-off as a brand new Bad Debt Expense when a provision already exists for it. If you set up a provision last quarter and now you're writing off a specific invoice it covered, the write-off goes against the provision — not the P&L. The profit impact already happened when you created the provision. Double-charging distorts your profitability figures and overstates your losses for the period.

Your Action for Today
Open your accounts receivable list. Find every invoice over 60 days old and run each one through the classifier above. Assign each one as either doubtful (needs a provision) or bad (needs a write-off).
- If doubtful — calculate the provision and post the journal entry this week
- If bad — gather the evidence, write it off, and stop chasing it
- If you're not sure — it's almost certainly doubtful at minimum
