Understanding Denied Write-Offs
The basics:
Why Write-Offs Get Denied
Write-offs get denied if:
- They're personal expenses (not business)
- They don't meet IRS requirements
- They're not ordinary and necessary
- They're illegal expenses
Result:
- Deduction disallowed
- May owe additional tax
- May face penalties
- May trigger audit
The Cost
If write-off is denied:
- You lose the deduction
- Owe tax on that amount
- May owe penalties
- Costs money
Example: Deducted $5,000 that gets denied
- Owe: ~$1,500-$2,000 (tax + penalties)
Personal Expenses
Understanding what's not deductible:
Personal Expenses Are Never Deductible
Not deductible:
- Personal meals (even if discussing business)
- Personal clothing (even if only worn for work)
- Personal phone (only business portion deductible)
- Personal internet (only business portion deductible)
- Personal travel (even if you work during vacation)
- Personal expenses of any kind
Key: Personal expenses remain personal, even if used for work sometimes
Real Examples
Example 1: Personal meal
- NOT deductible (personal expense, even if you discuss business)
Example 2: Personal clothing
- NOT deductible (regular clothing, even if only worn for work)
Example 3: Personal phone bill
- NOT deductible (only business portion is deductible)
Commuting Expenses
Understanding commuting:
Commuting Is Never Deductible
NOT deductible:
- Driving from home to first client (commuting)
- Driving from last client to home (commuting)
- Regular commute to office
What IS deductible:
- Driving between client locations
- Driving to business errands
- Driving while working (delivery, etc.)
Real Examples
Example 1: Drive from home to first client
- NOT deductible (commuting)
Example 2: Drive from Client A to Client B
- Deductible (business travel)
Example 3: Drive from last client to home
- NOT deductible (commuting)
Regular Clothing
Understanding clothing deductions:
Regular Clothing Is Not Deductible
NOT deductible:
- Suits, dresses, regular clothing
- Clothing suitable for everyday wear
- Even if you only wear it for work
What IS deductible:
- Uniforms (not suitable for everyday wear)
- Costumes (for specific work)
- Protective clothing (required for work)
Real Examples
Example 1: Suit for client meetings
- NOT deductible (suitable for everyday wear)
Example 2: Uniform required for specific job
- Deductible (not suitable for everyday wear)
Example 3: Regular clothing you only wear for work
- NOT deductible (still regular clothing)
Personal Meals
Understanding meal deductions:
Personal Meals Are Not Deductible
NOT deductible:
- Personal meals (even if you think about business)
- Meals with no business purpose
- Regular meals
What IS deductible:
- Business meals (50% deductible, must be business-related)
- Must document: Who, what, why (business purpose)
Real Examples
Example 1: Personal lunch, no business purpose
- NOT deductible (personal expense)
Example 2: Business meal with client
- Deductible (50%, if business-related and documented)
Example 3: Meal where you discuss business but it's personal
- Usually NOT deductible (must be primarily business, not personal)
Capital Expenses (Sometimes)
Understanding capital expenses:
Some Capital Expenses Must Be Depreciated
Not immediately deductible:
- Very expensive equipment (over certain thresholds)
- Building improvements
- Some capital expenses
Must depreciate: Over several years (not immediate deduction)
But: Most equipment can be deducted immediately (Section 179, if under $2,500 or use Section 179)
Real Examples
Example 1: $1,500 computer
- Deductible immediately (under $2,500, can expense)
Example 2: $50,000 building improvement
- Must depreciate (can't deduct immediately)
Most freelancers: Equipment is under thresholds, can deduct immediately

Hobby Expenses
Understanding hobby vs. business:
Hobby Expenses Are Not Deductible
If IRS determines it's a hobby (not a business):
- Losses are NOT deductible
- Can only deduct expenses to extent of income
- Can't create a loss
How to avoid: Show profit motive, operate in businesslike manner, show profit in 2 out of 5 years
Real Examples
Example 1: Hobby (selling crafts for fun, consistently loses money)
- Losses NOT deductible (hobby, not business)
Example 2: Business (trying to make profit, operates like business)
- Losses deductible (business, not hobby)
Personal Portion of Expenses
Understanding business use percentages:
Only Business Portion Is Deductible
If expense is used for both business and personal:
- Only business portion is deductible
- Must calculate business use percentage
- Can't deduct 100% unless 100% business use
Real Examples
Example 1: Phone bill $1,200, 50% business use
- Deduct: $600 (50% of $1,200)
- NOT: $1,200 (entire bill)
Example 2: Internet $960, 80% business use
- Deduct: $768 (80% of $960)
- NOT: $960 (entire bill)
Example 3: Vehicle expenses $8,000, 70% business use
- Deduct: $5,600 (70% of $8,000)
- NOT: $8,000 (entire amount)
Real Examples and Scenarios
Let's work through scenarios:
Example 1: Denied Personal Expenses
Scenario: Deducted $3,000 in personal expenses
What was deducted:
- Personal meals: $1,000
- Personal clothing: $800
- Personal phone (100%): $1,200
IRS audit: Disallows all $3,000
- Owe: ~$900-$1,200 (tax + penalties)
Cost of mistake: $900-$1,200
Example 2: Denied Commuting
Scenario: Deducted 15,000 miles, but 5,000 were commuting
What was deducted: 15,000 miles × $0.67 = $10,050
IRS audit: Disallows 5,000 commuting miles
- Owe: ~$3,350 (tax on $3,350 deduction that was denied)
Cost of mistake: $3,350 in denied deduction
Example 3: Denied Home Office
Scenario: Claimed home office but space used for personal too
What was deducted: $1,500 home office
IRS audit: Disallows (doesn't meet exclusive use requirement)
- Owe: ~$450-$600 (tax + penalties)
Cost of mistake: $450-$600
