Box 16. Items Affecting Shareholder Basis
Code A. Tax-exempt interest income. Report on your return, as an item of information, your share of the tax-exempt interest received or accrued by the corporation during the year. Individual shareholders include this amount on Form 1040, line 8b. Generally, you must increase the basis of your stock by this amount.
Code B. Other tax-exempt income. Generally, you must increase the basis of your stock by the amount shown, but do not include it in income on your tax return.
Code C. Nondeductible expenses. The nondeductible expenses paid or incurred by the corporation are not deductible on your tax return. Generally, you must decrease the basis of your stock by this amount.
Code D. Property distributions. Reduce the basis of your stock (as explained earlier) by distributions, not reported on Form 1099-DIV, of property or money. This amount will include any amounts included in income with respect to new clean renewable energy, qualified energy conservation, qualified school construction, build America, or (for bonds issued after October 3, 2008) qualified zone academy bonds. If these distributions exceed the basis of your stock, the excess is treated as capital gain from the sale or exchange of property and is reported on Form 8949 and Schedule D (Form 1040).
Code E. Repayment of loans from shareholders. If these payments are made on a loan with a reduced basis, the repayments must be allocated in part to a return of your basis in the loan and in part to the receipt of income. See Regulations section 1.1367-2 for information on reduction in basis of a loan and restoration in basis of a loan with a reduced basis. See Rev. Rul. 64-162, 1964-1 (Part 1) C.B. 304 and Rev. Rul. 68-537, 1968-2 C.B. 372, for details.
