Section 179 in 2026, with the phase-out applied

Equipment has to be placed in service by 2026-12-31 to claim the 2026 write-off, and with integration and installation inside the project that decision is being made now. The trap is the phase-out: the dollar limit falls by $1 for every $1 of qualifying property above $4,090,000, so a large project cannot expense the amount it elects. CaseProof applies §179 first, then 100% bonus depreciation to the remainder, then straight-line — by tax year.

1 · The vendor's quote, line by line

Paste or upload the quote's own line items as CSV rows. Every value is echoed as the vendor wrote it — CaseProof never re-prices a line, and a line the quote leaves blank is reported unpriced, not $0.

Header: item, amount_usd, optional category and note.

2 · Your case

The bid structure, your staffing sheet and your tax position as JSON. Money is integer cents; a term you do not state is reported unstated and blocks a pass — it is never filled in for you.

Worked scenarios: every number is a stated input, and the vendor's claims are reproduced by the same engine that audits the buyer's case.

Pick a worked scenario or paste your own case, then run the audit. Nothing is calculated until you ask for it.
