Step 3.
Generally, the entire amount of gain from the sale of trade or business property included in each installment payment is treated as unrecaptured section 1250 gain until the total unrecaptured section 1250 gain figured in Step 2 has been used in full. Figure the amount of gain treated as unrecaptured section 1250 gain for installment payments received in 2025 as the smaller of (a) the amount from line 26 or line 37 of your 2025 Form 6252, whichever applies; or (b) the amount of unrecaptured section 1250 gain remaining to be reported. This amount is generally the total unrecaptured section 1250 gain for the sale reduced by all gain reported in prior years (excluding section 1250 ordinary income recapture). However, if you chose not to treat all of the gain from payments received after May 6, 1997, and before August 24, 1999, as unrecaptured section 1250 gain, use only the amount you chose to treat as unrecaptured section 1250 gain for those payments to reduce the total unrecaptured section 1250 gain remaining to be reported for the sale. Include this amount on line 4.
