If neither a qualifying infrastructure basis nor another reduced-amount basis is established, the standard US$1,050,000 applies instead of US$800,000 at the researched date. Assess any alternative basis before treating the higher amount as automatic. Budget government, professional and project charges separately and review which spending, if any, qualifies as invested capital. Obtain the administrative charge and its refund terms in writing. Separate the charges by who receives them. Project-level administrative charges go to the sponsor, professional fees to advisers you appoint, government charges to the agency. Only one of those three has an interest in the total appearing small, so ask each to quote its own figure and confirm official charges from the source.
Pricing the two outcomes side by side
Write both totals on one page before any deposit. Note also that your capital must remain at risk and that there is no universal rule returning it after two years, nor a single sustainment period that applies to everyone. Where funds are gifted or come from a sale to a related party, expect the source and path to be documented closely; neither is automatically disqualifying.
Add the cost nobody quotes: what an unsupported basis, a redemption that does not happen, or a stalled project would mean for the household's own finances. Capital must remain at risk, so a plan depending on its return by a particular date rests on something the law does not promise.
