Answer: After January 19, 2025, but with a catch.
The One Big Beautiful Bill Act (https://veritaxadvisors.com/tax-credit-blog/unpacking-the-one-big-beautiful-bill) made 100% bonus depreciation permanent. To qualify, property must be both acquired and placed in service after January 19, 2025. January 20, 2025 is the first qualifying day.
Some things to watch:
📅 Acquisition date matters. Property acquired on or before January 19, 2025 still follows the old phase-down (40% in 2025, 20% in 2026, 0% after), even if it was placed in service later. This is usually the date a binding contract was signed.
⚙️ “Placed in service” means available for its intended use, which isn’t always the purchase or delivery date.
🏢 The property has to qualify. That generally means tangible property with a recovery period of 20 years or less. Buildings themselves usually don’t qualify, but a cost segregation study can identify components that do.
