South Carolina Additions to Income
Out of State Losses
If you have reported losses from out-of-state rental property, a business located outside South Carolina, or losses from real property located out of state, enter the amount shown on your federal return here. You must also include any related expenses, such as investment interest. Enter the total of these losses and related expenses on this line. Personal service income (W-2 or business wages) is taxable to South Carolina no matter where it is earned.
National Guard and Military Reserve Expenses-
Because inactive duty military reserve income is taxed for federal purposes but deductible on your South Carolina return, you must add back the amount of the federal deduction for expenses related to this income.
Other State and Political Interest Income on Obligations
Interest income on obligations of states and political subdivisions other than South Carolina must be added. In the case of a mutual fund, add back the percentage of exempt interest income attributable to out-of-state non federal obligations.
