Form 4797 Sales of Biz Property:

 

Property A

(d) Gross Sales Price   (e) Deprec Allowed   (f) Cost or other basis   (g)  Gain/loss

$560                                    $362                             $998.                                $   -76.

 

Property B

(d) Gross Sales Price   (e) Deprec Allowed  (f) Cost or other basis     (g) Gain/loss

$610                                   $511.                            2,168.                              $  -1,047. 

 

Since the % of use is so close, I do not understand how the losses in column G are so different.  I do not know where the calculations for (f) cost or other basis is generated from.   I entered $32,000 as the original purchase price (no trade or prior business use when vehicle placed in service nor any expense of sale). 

 

Please advise!
