The IRS accepted every receipt. It still won.

For years, Pecandarosa Ranch looked like a working farm. There was a pecan grove of nearly five hundred trees, along with horses, hay, cattle, and a twenty two thousand square foot arena. Every year the ranch reported a loss, and every year that loss was deducted against the owners' substantial income from a successful S corporation. On paper it read like an ordinary farm having a rough stretch.

Then the IRS reframed the whole thing. It never claimed the expenses were fabricated or unsubstantiated, and it accepted that the spending was real. Its position was more fundamental. Under Section 183, the ranch was not an activity engaged in for profit, and without a profit motive the losses were not deductible at all.

The Tax Court agreed. It applied the nine factors the regulations use to test profit intent, and six of them cut against the owners. What sank the case was not a missing receipt. It was the absence of a business run like one. There was no contemporaneous business plan, and the only plan in the record was written during the audit. The books existed to prepare the return rather than to run anything, with no general ledger, a personal bank account handling the money, and no tracking of which activity made or lost anything. The losses ran for more than a decade and totaled roughly $2.9 million, sheltering millions in outside income with no realistic path to ever earning them back.

The lesson lands differently than most substantiation cases, and that is what makes it worth reading. Keeping receipts is the floor, not the test. A venture that wants its losses respected has to behave like a business while the years are happening: a written plan, separate accounts, real books, and course corrections when the numbers stay red. A binder assembled once the examination begins tells the court exactly when the business thinking started.
