100% write-offs, primarily through bonus depreciation, allow businesses to immediately deduct the full cost of qualifying new and used assets (like equipment, machinery, vehicles, and certain improvements) in the year they're placed in service, rather than depreciating them over years, significantly boosting cash flow and lowering taxes, with recent laws making this 100% deduction permanent for assets acquired after January 19, 2025.
