What is Bonus depreciation?

In short

Bonus depreciation is an additional first-year deduction for qualified property. The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for property acquired after January 19, 2025.

Key takeaways

  • Unlike Section 179, it has no dollar limit and can create a net operating loss.
  • It applies automatically unless the taxpayer elects out, by class of property.
  • Order: Section 179 first, then bonus depreciation, then regular depreciation on any remaining basis.
