How this was worked out
Work shownrecomputed as you type
Pool = non-recaptured net section 1231 losses of the 5 most recent preceding years
Ordinary income = min(net section 1231 gain, pool)
Long-term capital gain = net section 1231 gain - ordinary income

The formulas

  • Pool = non-recaptured net section 1231 losses of the 5 most recent preceding years
  • Ordinary income = min(net section 1231 gain, pool)
  • Long-term capital gain = net section 1231 gain - ordinary income

How it works

When gains from business property held more than a year exceed the losses, net section 1231 gain is treated as long-term capital gain. When losses exceed gains, the net loss is ordinary. Section 1231(c) stops a taxpayer from taking ordinary losses in one year and capital gains in the next: net gain is ordinary income up to the non-recaptured net section 1231 losses of the five most recent preceding years.

Losses already recaptured in a prior year are excluded, so enter only the amounts not yet recaptured. This tool starts from a net gain you have already computed. Depreciation recapture under other sections is not modeled.

Common questions

Why does the lookback matter?

It makes sure a recent ordinary loss is paid back with ordinary income before later gains get capital gain rates.

What counts as non-recaptured?

A net section 1231 loss from the five prior years that has not already been used to convert a later gain to ordinary income.

Does it apply to a net loss year?

No. A net loss is ordinary and adds to the pool for later years.
