Quick Answer
The basis of converted personal property is the lesser of fair market value at conversion or original cost basis. For a $3,000 computer bought personally and worth $1,800 when converted to business, your depreciation basis is $1,800, limiting your total depreciation deductions to this amount over the asset's recovery period.

Best for consultants dealing with complex basis calculations on high-value converted equipment
Understanding basis for converted personal property
The tax basis of personal property converted to business use is determined by a specific IRS rule found in Publication 946: your basis is the lesser of the property's fair market value at the time of conversion or your original adjusted cost basis in the property.
This "lesser of" rule is designed to prevent taxpayers from claiming inflated depreciation deductions on assets that have already declined in value during personal use.
The basis calculation formula
Conversion Basis = LESSER OF:
1. Fair market value at conversion date
2. Original cost basis (purchase price + improvements - personal depreciation)
Detailed example: High-value consulting equipment
Dr. Martinez, a management consultant, purchased a high-end workstation and professional equipment for personal use before starting her consulting practice:
Equipment purchased personally in 2022:
Fair market values at business conversion (January 2026):
Basis calculation:
Since FMV ($5,600) is less than original cost ($8,500), her depreciation basis is $5,600.
Annual depreciation impact:
Original cost basis adjustments
Your original cost basis isn't always the purchase price. It can be adjusted by:
Increases to basis:
Decreases to basis:
Example with basis adjustments:
Original laptop: $3,000 + $200 sales tax + $400 RAM upgrade = $3,600 adjusted basis
Fair market value at conversion: $2,100
Conversion basis: $2,100 (lesser of $3,600 vs $2,100)
Section 179 and bonus depreciation implications
The conversion basis limitation also affects Section 179 expensing and bonus depreciation:
Section 179 example:
Converted equipment with $8,000 FMV (less than $10,000 original cost)
Record-keeping requirements for basis determination
For original cost basis:
For fair market value:
Special considerations for software and intangible property
Software and licenses require special attention:
Perpetual licenses: Use current replacement cost or upgrade pricing
Subscription software: Cannot be converted (no ownership interest)
Custom software: May require professional valuation
What you should do
1. Document original purchase costs with receipts and proof of payment
2. Research fair market values using multiple comparable sources
3. Calculate the lesser amount as your depreciation basis
4. Maintain detailed records supporting your basis determination
5. Consider professional appraisals for high-value equipment (>$10,000)
6. Use our deduction finder to ensure proper classification and depreciation schedules
Key takeaway: Converted property basis is limited to fair market value at conversion, which can be 30-50% less than original cost for technology equipment, significantly impacting total depreciation deductions available over the asset's life.
Key Takeaway: The basis of converted personal property is the lesser of fair market value or original cost, often limiting depreciation deductions to 30-50% of the original purchase price for technology equipment.
Typical basis retention rates by equipment type when converting from personal to business use
| Equipment Type | Typical Retention Rate | Example: $2,000 Original Cost | Conversion Basis |
|---|---|---|---|
| Computers/Laptops | 40-60% | $2,000 | $800-$1,200 |
| Professional Cameras | 70-85% | $2,000 | $1,400-$1,700 |
| Office Furniture | 60-80% | $2,000 | $1,200-$1,600 |
| Software (Perpetual) | 70-85% | $2,000 | $1,400-$1,700 |
| Smartphones/Tablets | 30-50% | $2,000 | $600-$1,000 |

Best for freelancers converting common business equipment like computers and office furniture
Practical basis calculations for typical freelancer equipment
As a freelancer, you're likely converting everyday equipment like computers, printers, office furniture, and software. Understanding how the "lesser of" rule affects these common items can help you plan your deductions more effectively.
Common freelancer conversions and typical basis reductions
Computers and laptops:
Technology depreciates rapidly. A laptop purchased for $2,500 personally might have a fair market value of only $1,500-$1,800 after 2-3 years of personal use. Your basis is limited to this lower amount.
Office furniture:
Furniture typically depreciates more slowly. A $1,200 desk might retain $900-$1,000 in fair market value after several years, providing a better basis retention rate.
Software:
Perpetual software licenses often retain value well. Adobe Creative Suite or Microsoft Office purchased for $800 might still have $600-$700 fair market value at conversion.
Mixed-use property complications
If you use converted property for both business and personal purposes, you must further reduce the basis:
Example:
Only the business portion can be depreciated, further limiting your deductions.
Timing strategy for conversions
The conversion date affects your basis calculation. Converting equipment earlier (when FMV is higher) gives you a larger basis, but you can only convert when you actually begin using it for business.
Strategic consideration: If you're planning to start freelancing, document the fair market value of equipment you expect to convert before values decline further.
Key takeaway: For typical freelancer equipment, expect the conversion basis to be 60-80% of original cost for furniture and software, but only 40-60% for computers and electronics due to rapid depreciation.
Key Takeaway: Typical freelancer equipment conversions result in basis reductions of 20-40% for furniture/software and 40-60% for technology, limiting available depreciation deductions.

Best for creators dealing with cameras, video equipment, and specialized content creation tools
Creator equipment basis: cameras, video gear, and studio equipment
Content creators often have specialized equipment that follows different depreciation patterns than standard business equipment. Understanding these patterns helps optimize your conversion timing and basis calculations.
Camera and video equipment basis considerations
Professional cameras and lenses typically retain value better than consumer electronics:
High-end camera example:
Professional lenses:
Studio setup conversions
Many creators build home studios with personal purchases before monetizing:
Example studio conversion:
Editing equipment and software
High-performance editing computers and professional software:
Gaming PC converted to editing workstation:
Professional software suite:
Strategic timing for creator conversions
Unlike computers, creator equipment may appreciate or hold value:
Consider: Research current market values before assuming depreciation. Some creator equipment may have fair market values equal to or exceeding original cost.
Key takeaway: Creator equipment often depreciates more slowly than standard technology, with cameras and professional gear typically retaining 70-85% of original value, providing larger depreciation bases upon conversion.
Key Takeaway: Creator equipment typically retains 70-85% of original value compared to 40-60% for standard technology, providing larger depreciation bases and more valuable conversions.
