Summary

An S corporation normally does not pay the regular corporate income tax. Its taxable income is figured much like an individual’s, but some items must be shown separately, certain deductions are not allowed to the corporation, some corporate rules about organization costs and special adjustments still apply, and a special rule can apply if the company was a regular (C) corporation in any of the 3 years before the S election. Most tax elections for items from an S corporation are made by the corporation itself. Two exceptions — elections about mining exploration costs and elections about foreign taxes — must be made by each shareholder. If a company used the LIFO inventory method as a C corporation before becoming an S corporation, any extra tax because of switching is called the “LIFO recapture amount” (the FIFO inventory amount minus the LIFO amount). That extra tax must be paid in 4 equal yearly installments. The first installment is due with the tax return for the last C year (no extensions), and the next three are due with the returns for the next three years. The law fixes how those due dates affect interest. Inventory terms and how to count inventory amounts are set by the rules about LIFO, retail valuation, or cost-or-market, and the law limits certain group and other technical rules for this recapture tax.
