If you extend credit to customers, some invoices won’t get paid. Bad debt expense is the estimate of those uncollectible amounts, recorded so your financial statements don’t overstate revenue or accounts receivable. Under accrual accounting, it ensures you match expected losses to the same period as the related sales.
What is bad debt expense?
Bad debt expense is the portion of accounts receivable you don’t expect to collect. You record it as an operating expense on your income statement to match expected losses with the revenue that generated them.
- Bad debt expense meaning: The estimated amount of receivables you won’t collect from customers
- Where it’s recorded: Operating expense on the income statement, typically within selling, general, and administrative (SG&A) expenses
- Why it matters: Keeps revenue realistic, supports GAAP compliance, and prevents overstating assets
When you extend credit, not every customer pays in full. Recording bad debt expense ensures your financial statements reflect the net amount you actually expect to collect, not just the total you billed.
What causes bad debts
Bad debts happen when customers can’t or won’t pay what they owe. Understanding the root causes helps you tighten credit controls and reduce future write-offs.
- Customer bankruptcy or insolvency: When a customer shuts down or enters bankruptcy, outstanding invoices may become uncollectible
- Cash flow problems: Customers facing liquidity issues may delay payments indefinitely or stop paying altogether
- Billing disputes: Disagreements over pricing, scope, or delivery can stall payment until the issue is resolved
- Fraudulent transactions: Some buyers never intend to pay, especially in high-risk or lightly vetted credit environments
- Economic downturns: Recessions or industry slowdowns can reduce customers’ ability to meet obligations
Tracking these patterns in your receivables helps you adjust credit limits, payment terms, and collection strategies before balances turn into write-offs.
Is bad debt an asset or expense?
Bad debt is an operating expense, not an asset. It reduces net income on your income statement in the period you estimate the loss.
It’s easy to confuse bad debt expense with the allowance for doubtful accounts, but they serve different purposes. The allowance is a contra-asset on the balance sheet that reduces gross accounts receivable to net realizable value, the amount you actually expect to collect. The expense affects your profit and loss (P&L) statement, while the allowance adjusts your balance sheet.
Why bad debt expense matters
Bad debt expense directly affects your profitability, cash flow forecasts, and credibility with stakeholders. Even small percentages can translate into meaningful dollar losses.
Bad debts can also distort your balance sheet and skew performance metrics if you fail to estimate them properly. Accurate bad debt recognition also strengthens your financial reporting, giving lenders and investors a clearer view of your company’s health.
Because accounts receivable is a core component of working capital, managing bad debt expense directly improves your liquidity, forecasting accuracy, and overall working capital efficiency.
Recording bad debt expense helps you:
- Improve financial reporting accuracy: Keep revenue and receivables aligned with economic reality
- Forecast cash flow more realistically: Avoid overstating available funds and plan working capital with confidence
- Maintain GAAP compliance: Properly apply the allowance method under generally accepted accounting principles (GAAP)
How to calculate bad debt expense
You can calculate bad debt expense using one of four methods. The percentage of sales, percentage of receivables, and aging methods comply with GAAP. The direct write-off method is simpler but used only for tax reporting.
Percentage of sales method
This income statement approach estimates bad debt as a percentage of total credit sales based on historical default rates.
Bad debt expense = Total credit sales * Estimated uncollectible %
Example:
- Scenario: Annual credit sales total $800,000, and historically 1.5% goes uncollected
- Calculation: $800,000 * 0.015 = $12,000
This method focuses on matching expense to revenue in the current period.
Percentage of receivables method
This balance sheet approach applies an estimated uncollectible percentage to your ending accounts receivable balance.
Required allowance = Total accounts receivable * Estimated uncollectible %
Example:
- Scenario: Accounts receivable totals $200,000, and you estimate 3% is uncollectible
- Calculation: $200,000 * 0.03 = $6,000
If your existing allowance balance is $2,000, you record $4,000 in bad debt expense to increase the allowance to $6,000.
This method focuses on adjusting the allowance account to the correct ending balance.
Aging of accounts receivable method
The aging method segments receivables by how long invoices have been outstanding. Older balances carry higher estimated default rates.
| Aging bucket | Balance | Estimated uncollectible % | Estimated bad debt |
|---|---|---|---|
| 0–30 days | $100,000 | 1% | $1,000 |
| 31–60 days | $50,000 | 5% | $2,500 |
| 61–90 days | $30,000 | 15% | $4,500 |
| 90+ days | $20,000 | 30% | $6,000 |
| Total | $200,000 | $14,000 |
This method is more precise than a flat percentage because it reflects collection risk based on invoice age.
Direct write-off method
The direct write-off method records bad debt only when a specific invoice becomes uncollectible. It does not comply with GAAP because it violates the expense recognition principle.
Pros:
- Simple to apply: No estimates or reserve tracking required
- Practical for small businesses: Often used by companies with minimal credit risk or those on cash-basis accounting
Cons:
- Delays expense recognition: The expense may be recorded long after the related revenue
- Distorts profitability: Large write-offs can materially impact a later period
For tax purposes, the IRS requires the direct write-off method. For financial reporting under GAAP, you must use the allowance method.
Journal entry for bad debt expense
Bad debt journal entries depend on whether you’re estimating losses, writing off a specific account, or recovering a previously written-off balance.
Recording the initial estimate
Under the allowance method, you estimate uncollectible amounts and record bad debt expense. This entry does not affect individual customer balances.
| Account | Debit | Credit |
|---|---|---|
| Bad debt expense | $6,000 | |
| Allowance for doubtful accounts | $6,000 |
This entry increases expenses and builds the allowance reserve on the balance sheet.
Writing off a specific uncollectible account
When you determine a specific receivable is uncollectible, you write it off against the allowance. This does not impact the income statement because the expense was already recorded.
| Account | Debit | Credit |
|---|---|---|
| Allowance for doubtful accounts | $2,500 | |
| Accounts receivable | $2,500 |
The write-off reduces both accounts receivable and the allowance.
Recovering a previously written-off account
If a customer later pays, you first reverse the write-off and then record the cash receipt.
Entry 1: Reinstate the receivable
| Account | Debit | Credit |
|---|---|---|
| Accounts receivable | $2,500 | |
| Allowance for doubtful accounts | $2,500 |
Entry 2: Record the cash receipt
| Account | Debit | Credit |
|---|---|---|
| Cash | $2,500 | |
| Accounts receivable | $2,500 |
This restores the allowance balance and properly reflects the recovered payment.
Where bad debt expense appears on financial statements
Bad debt expense appears on your income statement, while the allowance for doubtful accounts appears on your balance sheet.
- Income statement: Bad debt expense is recorded as an operating expense, typically within SG&A. It reduces net income in the period you estimate uncollectible accounts.
- Balance sheet: The allowance for doubtful accounts is a contra-asset that reduces gross accounts receivable to net realizable value, the amount you actually expect to collect
Together, these entries ensure your financial statements reflect both the expected loss and the adjusted value of your receivables.
Bad debt expense vs. allowance for doubtful accounts
Bad debt expense and the allowance for doubtful accounts are related, but they serve different accounting purposes. One affects your income statement, and the other adjusts your balance sheet.
Bad debt expense records the estimated loss in the current period. The allowance accumulates those estimates over time and reduces accounts receivable to net realizable value.
| Aspect | Bad debt expense | Allowance for doubtful accounts |
|---|---|---|
| Type | Operating expense | Contra-asset |
| Statement | Income statement | Balance sheet |
| Purpose | Records estimated loss for period | Reduces AR to net realizable value |
| Timing | Recorded when estimate is made | Adjusted over time, reduced by write-offs |
Understanding the distinction helps you interpret financial statements correctly and avoid overstating revenue or assets.
When to write off bad debt
You should write off bad debt when it becomes clear the amount is uncollectible and further collection efforts are unlikely to succeed.
Most companies wait until they’ve exhausted reasonable steps, such as follow-ups, payment plans, or collection agency involvement. Common triggers include:
- Customer bankruptcy: Once a customer files for bankruptcy, full recovery becomes unlikely
- Failed collection efforts: Multiple notices, calls, or agency attempts haven’t produced payment
- Excessive aging: The account exceeds your internal threshold, often 180 or 365 days past due
- Customer disappearance or closure: The business shuts down or becomes unreachable
For tax purposes, you must demonstrate the debt is genuinely worthless before claiming a deduction. Review the IRS guidance on business bad debts and maintain documentation of your collection efforts to support the write-off.
How to minimize bad debt expense
Reducing bad debt starts with tightening credit controls and staying proactive with collections. The earlier you identify risk, the less likely invoices turn into write-offs.
Establish clear credit policies
Screen new customers before extending credit. Run credit checks, set limits based on financial health, and define payment terms clearly—whether that’s net 30 or net 60. Clear expectations reduce disputes and improve payment behavior.
Monitor accounts receivable aging reports
Review your AR aging report regularly to spot overdue balances early. The longer an invoice remains unpaid, the lower your likelihood of collection. Tracking aging trends helps you adjust credit limits or escalate follow-ups before balances become uncollectible.
Send payment reminders promptly
Automate reminders at key intervals: before the due date, on the due date, and at defined past-due milestones. Consistent communication keeps invoices top of mind and signals that you actively manage receivables.
Offer flexible payment options
If a customer is struggling, structured payment plans can increase recovery rates. Partial payment is often better than a full write-off. Early payment incentives can also shorten your cash conversion cycle and reduce exposure.
Use automation for AR tracking and collections
Automated AR tools give you real-time visibility into receivables risk. They flag aging invoices, identify repeat late payers, and streamline follow-ups so small delays don’t compound into large losses.

FAQs
The IRS allows you to deduct business bad debts in full as ordinary losses in the year they become worthless. You must use the direct write-off method for tax purposes and prove the debt is genuinely uncollectible. Document your collection efforts and the circumstances that made the debt worthless.
Yes. If you recover a previously written-off account, you reverse the original write-off entry and record the cash receipt. This may create income in the recovery period, depending on when the original expense was recorded.
Bad debt refers to receivables confirmed as uncollectible—you've determined you won't collect and have written them off. Doubtful debt (or doubtful accounts) represents receivables you estimate may become uncollectible but haven't written off yet. The allowance for doubtful accounts captures this uncertainty.
Most companies record bad debt expense monthly or quarterly as part of the closing process. This ensures your financial statements accurately reflect estimated uncollectible amounts and keeps your allowance balance aligned with current receivables risk.
