Contractors: 100% bonus depreciation is back, and it is permanent.
The One Big Beautiful Bill Act restored the full first-year deduction for qualifying equipment, machinery and vehicles placed in service after January 19, 2025. No more phase-down. No more spreading the write-off over five years.
But here is the part nobody is talking about: the IRS is operating with reduced staffing, and that makes YOUR documentation the difference between a clean return and a months-long review.
Before you claim it this year:
✅ Confirm the actual placed-in-service date for every asset (a signed contract does not always set the clock)
✅ Clean up your fixed-asset ledger, ghost assets invite questions
✅ If you are doing a cost segregation study on a building, make sure it is engineering-based and ties to IRS guidance
✅ Keep invoices, cost allocations and capitalization policies organized BEFORE filing season
The deduction is generous. The paperwork has to match.
At Catherine Accounting & Tax Services LLC, we help contractors and construction business owners capture every dollar of accelerated depreciation with records that hold up.
