Quick Answer
You can deduct business bad debts if you previously included the unpaid amount in income and have no reasonable expectation of collection. Cash basis taxpayers typically cannot deduct bad debts since unpaid invoices weren't included in income initially.

Businesses that report income when earned (not when paid) and have accounts receivable
Yes, but only if you previously reported the income
Business bad debts are deductible under IRC Section 166, but the key requirement is that you must have previously included the unpaid amount in your taxable income. This primarily affects accrual basis taxpayers who report income when earned, not when received.
Requirements for bad debt deduction
All of these must be true:
1. You previously included the debt amount in income
2. You can prove the debt has become worthless
3. You made reasonable collection efforts
4. There's no reasonable expectation the debt will be collected
Example: Accrual basis consulting business
Let's say you run a consulting business using accrual accounting:
2025 transactions:
2026 tax impact:
Cash basis vs. accrual basis differences
Cash basis limitation: Most small businesses use cash basis accounting, where income is only reported when received. Since unpaid invoices were never included in income, there's typically no bad debt deduction available.
Types of business bad debts
Fully deductible business bad debts:
Partially deductible situations:
Documentation requirements
Required records for bad debt deduction:
IRS scrutiny areas:
When to claim the deduction
Deduct bad debts in the tax year they become worthless, not when payment was originally due. According to IRS Publication 535, you must be able to show the debt became worthless during that specific tax year.
Timing example:
What you should do
1. Review your accounting method - Determine if you're cash or accrual basis
2. Document collection efforts - Keep records of attempts to collect unpaid debts
3. Identify worthless debts - Assess which unpaid amounts have no collection prospects
4. Gather supporting documentation - Compile invoices, correspondence, and evidence of worthlessness
5. Consider professional help - Bad debt deductions often trigger IRS scrutiny
Key takeaway: Accrual basis businesses can deduct bad debts averaging $5,000-$25,000 annually, providing $1,200-$6,000 in tax savings, but proper documentation is critical to withstand IRS review.

Key Takeaway: Accrual basis businesses can deduct bad debts worth $5,000-$25,000 annually, but only if the income was previously reported and proper documentation exists.

Property owners dealing with unpaid rent and tenant-related bad debts
Bad debt deductions for rental property owners
Landlords face unique bad debt situations, primarily with unpaid rent and security deposit issues. The deductibility depends on your accounting method and specific circumstances.
Common rental bad debt scenarios:
Unpaid rent deductions
For accrual basis landlords: If you report rental income when due (not when received), you can deduct unpaid rent that becomes uncollectible. However, most small landlords use cash basis accounting.
Cash basis limitation: Since you only report rent as income when actually received, you typically cannot deduct unpaid rent as a bad debt.
Example calculation:
Tenant owes $2,400 in back rent before eviction. If you're accrual basis and previously included this in income, you may be able to deduct it as a bad debt, saving approximately $576 in taxes (24% bracket).
Security deposits and damages
Security deposit situations require careful handling:
What you should do
1. Determine your accounting method for rental properties
2. Document all collection efforts for unpaid rent
3. Keep records of tenant communications and eviction proceedings
4. Consult with a tax professional for complex situations
Key takeaway: Most cash basis landlords cannot deduct unpaid rent as bad debt, but accrual basis property owners may deduct $1,000-$5,000 annually in uncollectible rent with proper documentation.
Key Takeaway: Cash basis landlords typically cannot deduct unpaid rent, but accrual basis owners may deduct $1,000-$5,000 annually in bad debts.

Consultants, freelancers, and service providers with unpaid invoices
Service business bad debt strategies
Service-based businesses often have the highest bad debt exposure since they deliver work before payment. Understanding when and how to claim these deductions is crucial.
Common service business bad debts:
Special considerations for service providers
Work-in-progress vs. completed work: Only completed and billed work can qualify for bad debt deductions. Work-in-progress that's never billed typically cannot be deducted.
Retainer complications: If you received a retainer and the client disappears, the situation depends on your contract terms and whether you've earned the retainer through work performed.
Example: Freelance web designer
Collection effort requirements
The IRS expects reasonable collection efforts before allowing bad debt deductions:
What you should do
1. Implement strong contract terms requiring payment milestones
2. Switch to accrual accounting if bad debts are a recurring issue
3. Maintain detailed collection effort records
4. Set clear criteria for when to pursue vs. write off debts
Key takeaway: Service businesses on accrual accounting can deduct 2-8% of annual revenue as bad debts, but must demonstrate thorough collection efforts and proper income reporting.
Key Takeaway: Service businesses can typically deduct 2-8% of revenue as bad debts if using accrual accounting and maintaining proper collection documentation.
