The loss harvest was $38,000. It happened in October. The CPA didn’t know about it.
The installment sale closed in November. The first-year gain was $52,000. The wealth manager didn’t know it was coming.
When the tax return was prepared in April, the $38,000 in losses offset $38,000 of the $52,000 installment gain. The remaining $14,000 was taxable. The harvest looked like a partial success. What it actually was: a missed coordination opportunity worth more than the $14,000 gap.
How the installment method works
When a seller structures a sale to receive payments over multiple years rather than all at once, gain is recognized proportionally as each payment arrives. A property generating $150,000 of capital gain, sold across three equal annual payments, produces $50,000 of recognized gain in each of three tax years rather than $150,000 in one.
The installment method exists because large gains are easier to absorb in smaller annual pieces. It is a tax-timing tool. Like all tax-timing tools, it works best when integrated with the rest of the tax picture.
The coordination problem
The wealth manager who harvests losses in October is looking at the investment portfolio. They see positions sitting at a loss and capture them before year-end. They know the portfolio’s capital gain picture for the current year. They do not know what the CPA is structuring in November.
The CPA who structures the installment sale in November is looking at the property transaction. They calculate the gross profit ratio, confirm the gain recognition schedule, and document the installment agreement. They know the sale’s tax profile across all three years. They do not know the portfolio harvested $38,000 in losses six weeks earlier.
In October, the harvest was sized to what was visible: the portfolio’s own gains and the general case for building loss carryforwards. It was not sized to the installment sale’s Year 1 gain of $52,000, because the wealth manager didn’t know about it.
In November, the payment schedule was not structured with awareness of the existing loss harvest. If the CPA had known about the $38,000 in losses, they might have loaded more gain into Year 1, where the harvest could fully offset it, rather than spreading it evenly. They might also have recommended harvesting additional losses before December 31 to cover more of Year 1’s gain.
Three years, coordinated and not
In the uncoordinated version: Year 1 closes with $14,000 in taxable gain after the partial offset. Year 2 arrives with $50,000 in installment gain and no offsetting losses. Nobody was planning for Year 2’s installment gain when Year 1’s portfolio decisions were made. Year 3 is the same.
In a coordinated version: knowing in October that a three-year installment sale was closing in November, the wealth manager harvests against the full expected installment gain, not just the portfolio’s internal picture. The CPA structures the payment schedule to match the available loss carryforward. Year 1’s gain lands where the harvest is. Years 2 and 3 are planned for rather than absorbed as surprises.
The difference is not the strategy. Both advisors were using legitimate, established tax techniques. The difference is whether anyone had both in view at the same time.
The seam
Installment sales generate gain on a schedule that is known in advance. Loss harvesting opportunities appear in portfolio positions throughout the year. These two facts create a coordination opportunity that most advisory structures miss.
The CPA sees the installment gain schedule but not the portfolio’s loss profile. The wealth manager sees the loss opportunities but not the installment gain schedule. Neither engagement model requires them to connect before the year closes.
The three-year installment gain is a $150,000 tax event spread across three calendar years. How much of it gets offset depends on whether anyone connected the harvest schedule to the gain schedule before Year 1 closed.
