Quick Answer
Yes, but only if you previously included the unpaid amount in your income using accrual accounting. Cash-basis businesses (83% of small businesses) cannot deduct bad debts because they never reported the income. For qualifying bad debts, you can deduct up to $3,000 per year ($1,500 if married filing separately) as a short-term capital loss.

Yes, accrual-basis businesses can deduct bad debts
Business bad debts are fully deductible as ordinary business expenses under IRC Section 166, but only if you use accrual accounting and previously included the unpaid amount in your taxable income. This creates a key distinction: you can only deduct income you've already been taxed on.
Requirements for business bad debt deduction
To qualify for a business bad debt deduction, you must meet these criteria:
1. Accrual accounting: You must use accrual method and have included the debt in income when earned
2. Business purpose: The debt must arise from your trade or business activities
3. Worthless debt: You must show the debt is partially or totally worthless
4. Documentation: Maintain records of collection efforts and debt worthlessness
How much can you deduct?
Business bad debts: Fully deductible against ordinary income with no annual limit. If a customer owes you $15,000 and declares bankruptcy, you can deduct the full $15,000.
Nonbusiness bad debts: Limited to $3,000 per year ($1,500 if married filing separately) as short-term capital loss. Excess amounts carry forward to future years.
Example: Consulting firm bad debt
Alex runs a marketing consultancy using accrual accounting. In 2025, he completed a $8,000 project and properly recorded it as income. The client filed bankruptcy in 2026 without paying.
Tax treatment:
At a 24% marginal rate, Alex saves $1,920 in federal taxes from this deduction.
Cash vs. accrual accounting impact
Cash-basis businesses (most small businesses) generally cannot deduct bad debts because they don't report income until payment is received. If you never reported the income, there's nothing to deduct.
Accrual-basis businesses report income when earned, regardless of payment. This allows bad debt deductions when customers don't pay.
Proving a debt is worthless
The IRS requires evidence that collection efforts have failed:
Partial vs. total worthlessness
Totally worthless: Deduct the full amount when you determine the debt will never be collected
Partially worthless: Deduct only the portion you determine is uncollectible. For example, if a customer owes $10,000 but you expect to collect $3,000 through bankruptcy proceedings, you can deduct $7,000.
What you should do
1. Document collection efforts: Keep records of all attempts to collect the debt
2. Establish worthlessness: Gather evidence that the debt cannot be collected
3. Timing matters: Claim the deduction in the year you determine the debt is worthless
4. Review prior years: Check if you have unclaimed bad debts from previous tax years
5. Consider changing to accrual: If bad debts are common, accrual accounting might provide better tax benefits

Cash-basis businesses: limited bad debt options
Most small businesses and freelancers use cash-basis accounting, which significantly limits bad debt deductions. Since you don't report income until payment is received, you typically can't deduct unpaid invoices as bad debts.
Exception for cash advances: If you advance your own money to a client (not just unpaid invoices), you may qualify for a nonbusiness bad debt deduction limited to $3,000 annually.
Alternative strategies for cash-basis businesses
While you can't deduct unpaid invoices, you can:
Deduct collection costs: Legal fees, collection agency fees, and court costs to collect debts are deductible business expenses
Write off related expenses: Deduct costs associated with the unpaid work (materials, subcontractor fees, travel expenses)
Consider payment terms: Require deposits or milestone payments to reduce bad debt exposure
Example: Freelance graphic designer
Sarah (cash-basis) completes a $5,000 logo design but the client disappears. She cannot deduct the $5,000 as a bad debt because she never reported it as income. However, she can deduct:
Key takeaway: Cash-basis businesses should focus on deducting collection costs and related expenses rather than the unpaid invoice amount itself.

Rental property bad debt considerations
Landlords face unique bad debt situations with unpaid rent, security deposit issues, and tenant damages. The deductibility depends on your accounting method and the nature of the debt.
Unpaid rent (accrual basis): If you use accrual accounting and reported rent as income when due (not when received), you can deduct unpaid rent as a bad debt when the tenant moves out or is evicted.
Unpaid rent (cash basis): Most landlords use cash accounting and cannot deduct unpaid rent as bad debt since they never reported it as income.
Security deposit complications
Security deposits create complex bad debt scenarios:
Example: Landlord bad debt scenario
Tom (cash-basis landlord) has a tenant who owes $3,000 in unpaid rent and causes $2,000 in damages beyond the $1,500 security deposit. The tenant disappears.
Cannot deduct: $3,000 unpaid rent (never included in income)
Cannot deduct: $2,000 in damages (not previously included in income)
Can deduct: Legal fees, court costs, and collection expenses as rental expenses on Schedule E
Key takeaway: Landlords using cash accounting cannot deduct unpaid rent as bad debt but can deduct all costs associated with collection efforts and legal proceedings.
