Bonus depreciation recapture is based on the year that is placed into services.As of right now, the bonus depreciation for 2024 is 60%.It is not likely that they will change the bonus depreciation retroactively to 2024.If they change the bonus depreciation for properties purchased in 2025, it will have no impact on a property you placed into service in 2024.
