Depreciation of Assets: Complete 2026 Guide for Small Business
How the depreciation of assets works, who qualifies, how much you can deduct, and how to document it properly.
The depreciation of assets is one of the most valuable — and most misunderstood — deductions available to small business owners. Here's exactly how to use it in 2026.
What it is
Deduct the cost of equipment, vehicles, and property over their useful life.
The numbers
MACRS tables by asset class. 5-year (computers), 7-year (office furniture), 27.5-year (residential rental), 39-year (commercial).
Who qualifies
To claim this deduction, you must:
1. Operate a business (sole prop, LLC, S-Corp, C-Corp, or partnership)
2. Be the correct entity type for this deduction
3. Document properly — the IRS requires contemporaneous records
How to claim it
Sole proprietors
Report on Schedule C of your personal 1040.
Multi-member LLCs / partnerships
Report at the entity level on Form 1065, flows to partners via K-1.
S-Corporations
Report on Form 1120-S, flows to shareholders via K-1.
C-Corporations
Deduct directly on Form 1120.
Documentation requirements
The IRS expects you to keep contemporaneous records — meaning you track it as it happens, not reconstruct at tax time.
Required:
- Dates and amounts
- Business purpose (one-sentence description)
- Receipts for $75 or more
- For vehicle/mileage: starting/ending odometer, route, purpose
- For travel: dates, locations, attendees, business discussed
Recommended: keep digital copies in your accounting software. Photograph paper receipts and attach to the transaction.
Common mistakes
1. Missing documentation — a receipt you lose isn't a deduction
2. Mixing personal and business — bright line: business from business account, personal from personal
3. Assuming "if I spent it, it's deductible" — only ordinary and necessary business expenses qualify
4. Not keeping records for 7 years — IRS audit window
5. Rounding up — the IRS notices nice round numbers
