                                          INSTRUCTIONS 
                                                         
Beginning with the 2021 tax year, a qualified entity can elect to have its active trade or business income taxed at a 3% flat 
tax rate imposed on the entity itself instead of its qualified owners. Electing qualified entities must use the I-435 to identify 
active trade or business income and calculate the tax. 
 
Electing entities will report the active trade or business income taxed at the entity level to their partners or shareholders on 
the SC K-1s. Partners or shareholders will use the I-335, Active Trade or Business Income Reduced Rate Computation, 
with their SC1040, Individual Income Tax Return, to account for active trade or business income taxed at the entity level.  
 
A qualified entity is a Partnership, S Corporation, or LLC taxed as a Partnership or S Corporation whose owners are all 
qualified owners or partnerships directly owned by qualified owners or by qualified owners through other partnerships. 
 
A qualified owner is a partner, shareholder, or member of a qualified entity who is: 
  · an individual 
  · a trust 
  · an estate 
  · an entity type not included in SC Code Sections 12-6-530 through 12-6-540 and 12-6-550 and not exempt from 
  South Carolina Income Tax 
 
Qualified entities elect each year whether or not to have the active trade or business income taxed at the entity level. The 
election must be made by the due date for filing the applicable Income Tax return, including any extensions.  
 
Active trade or business income is apportioned by the entity according to SC Code Section 12-6-2240. Active trade or 
business income does not include passive investment income and related expenses or capital gains and losses. No 
amounts included in active trade or business income should be treated as income from personal services allocated based 
on SC Code Section 12-6-2220(6). For more information, SC Code Sections are available at dor.sc.gov/policy. 
 
Line instructions 
Enter amounts from the federal Schedule K in Column A. Enter amounts allocated or apportioned to South Carolina from 
the Schedule SC-K in Column B. Enter South Carolina active trade or business amounts in Column C. Amounts entered 
in Column C should not be greater than the amounts entered in Column B.   
 
Line 1: Ordinary business income (loss) 
In Column C, enter amounts from Column B that are not capital gains or losses or passive investment income or losses. 
Do not enter income from personal services in Column C. 
 
Line 2 and Line 3: Net rental real estate income (loss)/other net rental income (loss) 
Rental income is typically passive investment income and not active trade or business income. In Column C, enter from 
Column B only rental income from the active trade or business of renting property if, based on all the facts and 
circumstances, the pass-through business either provides significant services or has substantial expenses in the rental 
business. The determination is based in part on the number of people employed to provide services and the types and 
amounts of expenses, other than depreciation. Examples of qualifying rents are those from operating a hotel or a short-
term car rental business. See IRC Section 1362(d) and applicable regulations for more information. 
 
Line 4: Guaranteed payments (from partnerships) 
In Column C, enter Column B guaranteed payments for use of capital that are not passive investment income. Do not 
include guaranteed payments for services. 
 
Line 5: Interest income 
Interest income is considered passive income and is not included in Column C unless it results from the sale of: 
  · stock in trade 
  · inventory 
  · property held for sale to customers in the ordinary course of trade or business 
  · services performed in the ordinary course of trade or business 
 
Line 6: Ordinary/qualified dividends 
Dividends are not included in active trade or business income or loss because they are passive investment income. 
 

Line 7: Royalties 
Royalties are considered passive investment income and are not included in Column C unless they are from the ordinary 
course of a trade or business of franchising or licensing property, or are active business computer software royalties as 
defined in IRC Section 543(d). 
 
Line 8 and Line 9: Net short-term and long-term capital gains (losses) 
Active trade or business income or loss does not include these amounts. 
 
Line 10: Net section 1231 gain (loss) 
After determining if gains and losses are capital, enter in Column C the net of ordinary gains and losses, but not capital 
gains or losses. 
 
Line 11: Other income (loss) 
In Column C, do not enter Column B capital gains or losses or passive investment income or losses. 
 
Line 12: Section 179 deduction 
In Column C, enter amounts from Column B that are not capital gains or losses or passive investment income or losses. 
 
Line 13: Other deductions

Add amounts in Column C. Enter the total active trade or business income to be taxed at the entity level on line 2 of the 
SC1065 or line 5 of the SC1120S. 
 
Line 15: Total active trade or business income taxed by another partnership or S Corporation 
Enter amounts that were already taxed, as shown on the SC K-1s provided by another partnership or S Corporation.  
 
Line 16: Taxable active trade or business income

117-201  mandates  that  any  person  required  to  make  a  return  to  the  SCDOR  must  provide  identifying  numbers,  as  prescribed,  for 
securing proper identification. Your Social Security Number is used for identification purposes. 

The Family Privacy Protection Act 
Under the Family Privacy Protection Act, the collection of personal information from citizens by the SCDOR is limited to the information 
necessary for the SCDOR to fulfill its statutory duties. In most instances, once this information is collected by the SCDOR, it is protected 
by law from public disclosure. In those situations where public disclosure is not prohibited, the Family Privacy Protection Act prevents 
such information from being used by third parties for commercial solicitation purposes.
