An Investor's Guide to 100% Bonus Depreciation in 2026
Bonus depreciation is a powerful tax incentive that allows businesses to accelerate the depreciation of qualifying assets, providing a significant upfront deduction. For the 2026 tax year, the bonus depreciation rate is 100%, allowing for a full deduction of the cost of eligible property in the year it is placed in service. This guide provides a comprehensive overview of bonus depreciation for 2026, including who qualifies, how to claim it, and common pitfalls to avoid.
What is Bonus Depreciation?
Bonus depreciation, also known as the additional first-year depreciation deduction, is a tax incentive that allows businesses to immediately deduct a large percentage of the purchase price of eligible assets, rather than writing them off over the “useful life” of that asset. The Bipartisan Budget Act of 2018 (BBA), and more recently the One, Big, Beautiful Bill Act (OBBBA), made significant changes to bonus depreciation, increasing it to 100% for qualified property placed in service after September 27, 2017, and permanently extending it for property acquired after January 19, 2025.
Who Qualifies for Bonus Depreciation?
To be eligible for bonus depreciation in 2026, the property must be one of the following:
- MACRS property with a recovery period of 20 years or less
- Computer software
- Water utility property
- Qualified improvement property
- Qualified film, television, and live theatrical productions
- Certain new and used property
The property must be acquired by the taxpayer after September 27, 2017, and placed in service after that date. For the permanent 100% bonus depreciation, the property must be acquired after January 19, 2025.
How to Claim Bonus Depreciation
Bonus depreciation is claimed on IRS Form 4562, Depreciation and Amortization. The form is filed with the business's annual tax return. For the 2026 tax year, you will use the version of Form 4562 revised for that year. In Part II, line 14, you will enter the special depreciation allowance for qualified property.
2026 Limits and Amounts
For qualified property acquired after January 19, 2025, and placed in service in 2026, the bonus depreciation rate is 100%. This means you can deduct the full cost of the asset in the first year. There is no limit on the amount of bonus depreciation a business can claim.
Common Mistakes to Avoid
- Incorrectly classifying property: Not all business property is eligible for bonus depreciation. Make sure your assets meet the specific requirements.
- Failing to properly elect out: If you don't want to claim bonus depreciation for a particular asset class, you must formally elect out on your tax return.
- Ignoring state tax laws: Not all states conform to the federal bonus depreciation rules. Check your state's specific regulations.
- Confusing bonus depreciation with Section 179: While both offer accelerated depreciation, they have different rules and limitations.
IRS Code Section Reference
