Excel Viewer Adobe® Reader Certain corporations elect to be treated as S corporations for Federal tax purposes. Electing to be treated as an S corporation allows income to flow through the corporation without being taxed until it is claimed as income by the shareholders. This avoids double taxation of corporate income. Here you will find data tables and SOI Bulletin articles concerning 1120S corporations. Featured areas: Integrated Business Data: Tables and articles that combine the annual SOI cross-sectional studies of corporation (C and S corporations), partnership, and nonfarm sole proprietorship data.
