Business Asset Write-Offs for 2026

 

Business Asset Write-Offs for 2026: What Business Owners Need to Know

Purchasing equipment, technology, vehicles, or making improvements to your business property can provide valuable tax savings—but only if you understand how the IRS asset write-off rules work.

For 2026, business asset write-offs generally follow this order:

1. Apply any Section 179 deduction.
2. Apply bonus depreciation.
3. Depreciate any remaining basis using MACRS depreciation.

Using these rules correctly can significantly reduce your taxable income and improve cash flow.

 

Section 179 Write-Offs in 2026

Section 179 allows eligible businesses to immediately expense qualifying business assets rather than depreciating them over several years.

2026 Section 179 Limits

• Maximum deduction: $2,560,000.
• Phase-out begins when qualifying property placed in service exceeds $4,090,000.

If your total qualifying purchases exceed the phase-out threshold, your available deduction is reduced dollar-for-dollar.

Taxable Income Limitation

Your Section 179 deduction generally cannot exceed taxable income from the active conduct of your trade or business. Any unused deduction may generally be carried forward to future tax years.

 

Qualifying Property

• Business equipment and machinery.
• Certain computer software.
• Qualified improvement property.
• Roofs.
• HVAC systems.
• Fire protection and alarm systems.
• Security systems for existing nonresidential buildings.

 

Important Exclusions

Section 179 generally does not apply to:

• Estates and trusts.
• Property acquired by gift or inheritance.
• Certain related-party acquisitions.
• Certain property used predominantly outside the United States.

 

Special SUV Limitation

For qualifying SUVs placed in service during 2026, the maximum Section 179 deduction is generally limited to $32,000.

 

Bonus Depreciation Write-Offs in 2026

Once any Section 179 deduction has been applied, businesses may qualify for bonus depreciation on the remaining basis of eligible assets.

 

Bonus Depreciation Rates

• 100% for qualified property acquired after January 19, 2025 and placed in service during 2026.
• 20% for qualified property acquired before January 20, 2025 and placed in service during 2026.

 

Qualifying Property

• MACRS property with a recovery period of 20 years or less.
• Certain computer software.
• Water utility property.
• Certain film, television, theatrical, and sound recording productions.

 

When Bonus Depreciation Does Not Apply

• Property required to use the Alternative Depreciation System (ADS).
• Property placed in service and disposed of during the same tax year.
• Property converted from business to personal use during the year it was acquired.
• Property for which the taxpayer elects out of bonus depreciation.

Businesses may elect out of bonus depreciation for an entire class of property if doing so better aligns with their long-term tax strategy.

 

MACRS Depreciation

After Section 179 and bonus depreciation are applied, any remaining basis is depreciated using the Modified Accelerated Cost Recovery System (MACRS).

Depending on the asset, MACRS generally uses:

• 200% declining balance for most 3-, 5-, 7-, and 10-year property.
• 150% declining balance for most 15- and 20-year property.
• Straight-line depreciation for nonresidential real property, residential rental property, qualified improvement property, and certain other assets.

The applicable depreciation convention generally is:

• Half-year convention for most personal property.
• Mid-quarter convention if the 40% test applies.
• Mid-month convention for real property.

 

Special Rule for Qualified Production Property

Separate from standard bonus depreciation, certain qualified production property may qualify for a 100% special depreciation allowance under IRC Section 168(n), provided all statutory construction, acquisition, election, and placed-in-service requirements are satisfied.

This provision may provide substantial tax benefits for qualifying manufacturing and production facilities.

 

How Business Asset Write-Offs Work Together

For most businesses, the process follows three simple steps:

1. Claim any available Section 179 deduction.
2. Apply bonus depreciation to the remaining basis.
3. Depreciate any remaining amount under MACRS.

Understanding this sequence helps ensure you maximize available deductions while remaining compliant with IRS rules.

 

Final Thoughts

Business asset write-offs remain one of the most valuable tax-saving opportunities available to businesses in 2026.

By properly applying Section 179, bonus depreciation, and MACRS depreciation, businesses can significantly reduce taxable income while investing in equipment, technology, and property improvements that support future growth.

Because deduction limits, acquisition dates, income limitations, and asset classifications all affect the outcome, proactive tax planning before making major purchases can produce substantial tax savings.
