The S corporation return, from the trial balance.
1120-S software prepares an S corporation's federal income tax return. Blanc Tax starts where your firm's work actually lives, the final trial balance in Excel, and produces a filing-ready Form 1120-S with every supporting schedule and a workpaper behind every figure. Partnerships on Form 1065 follow the same flow.
