A single Working Capital SAFE Harbor (WCSH) period can cover up to 31-months from the date you expect to receive a cash infusion from the QOF or elsewhere. To qualify for a WCSH, amounts received by you must meet the following requirements:
(A) These amounts are designated in writing for development of a trade or business in a qualified opportunity zone, including when appropriate the acquisition, construction, and/or substantial improvement of tangible property in such a zone.
(B) There is a written schedule consistent with the ordinary start-up of a trade or business for the expenditure of the working capital assets;
(C) The working capital assets are actually used in a manner substantially consistent with the writing and written schedule described in (A) and (B).
For “start-up businesses", the final regulations allow the initial 31-month WCSH to be extended for up to a maximum 62-month safe harbor period from the date of the first cash infusion, when a start-up will receive multiple cash infusions during its start-up phase.
