Form 1120-S Case Study

S-Corporation Return · Training Exercise

As part of the U.S. Business Tax Preparation curriculum, I prepared a mock Form 1120-S return for an S-corporation case study, covering shareholder allocations, income and expense classification, and the supporting schedules required for the filing.

What the exercise covered

  • Organizing S-corporation income and expense data
  • Working through shareholder allocation schedules
  • Completing Form 1120-S and supporting schedules
  • Reviewing entries against case study source data

Software used

Intuit ProConnect Tax and Drake Tax, applying the same organization and documentation habits used in bookkeeping and QuickBooks Online work.

This was completed as a training exercise, not an independently filed return. Actual client tax preparation is performed under professional guidance.
