Upon receipt of the C-268, a review of all tax types for which your corporation is responsible will be conducted. The corporation will be immediately notified of any delinquencies and has thirty days to comply. When the delinquencies are cleared, the corporation will be issued a Certificate of Tax Compliance.
Once the corporation receives the Certificate of Tax Compliance, it is required to file an Application for Reinstatement of a Corporation Dissolved by Administrative Action with the SCSOS. For more information about this form, visit the SCSOS website.
Yes. If you are a new corporation and you incorporated in the middle of an accounting period, you will be required to file a short period return. Example – You incorporated with the SCSOS November 1 and your accounting period is December 31. You will need to file a short period return for November 1 through December 31.
Yes. In order to change your accounting period, you may be required to file a short period tax return.
Example – If you are changing from a May filer to a December filer, you will be required to file a short period return from June 1 to December 31. Each part of a month is considered a full month for purposes of prorating the License Fee. (The License Fee is not computed based on the number of days in a short period.) Check the Change of Accounting Period box on the front of the return.
See SC Revenue Ruling #05-11 and SC Code Section 12-20-80(A) for more information on the License Fee proration.
The starting point in determining South Carolina taxable income is the corporation's federal taxable income. There are different tax rates for certain organizations. If you are filing:
To request a copy of a prior year return, complete an SC4506. You may choose to have copies of your prior year returns mailed or emailed to you. Allow 30 days to receive mailed copies. Social Security Numbers and Federal Employer Identification Numbers will be partially redacted from all copies.
If you used a paid preparer to file your return, your preparer should have a copy of your return.
To claim tax withheld on your behalf, attach supporting 1099s or I-290s. SCDOR does not accept South Carolina Schedule K-1, Partner Information (SC1065), or Settlement Statements as proof of withholding. If you are a fiscal year taxpayer, include a schedule of amounts withheld on a monthly basis. See SC Code Sections 12-8-590(D) and 12-8-1540(A).
You must complete a C-268, Certificate of Tax Compliance Request Form, and pay the $60 nonrefundable fee. For corporations, generally the request can be signed by an officer having legal authority to bind the corporation, or a person designated by the board of directors or other governing body.

Net operating loss (NOL) carrybacks are not allowed. Only carry forwards are allowed.
No, there is not a limited amount or percentage a corporation can carry forward to the next tax year.
To amend a Corporate Income Tax return, complete a new form and check the Amended Return box on the front of the return. Attach to the amended return an explanation of the adjustment, a copy of the original return filed, and a copy of the federal 1120X. If a copy of the original return is not provided, the amended return cannot be processed. The amended return must be submitted within 36 months from the date the original return was filed or due to be filed, whichever is later as required by SC Code Section 12-54-85.
Once the IRS completes an audit, the corporation has 180 days to file an amended return with the SCDOR. Include the IRS 4549 and 870, with the amended return, along with the 1574 letter, if available.
Report your address change using one of the following:
Yes. This information should be updated each year on the annual report (Schedule D) when filing your Corporate Tax return. Check the Change of Officers box on the front of the tax return.
A composite return is a single return filed by a partnership, S Corporation, or Limited Liability Company (LLC) taxed as a partnership or S Corporation on behalf of two or more nonresident participants.
A composite return allows S Corporations or Partnerships to compute and report the SC income and tax attributable to electing nonresident shareholders or partners on a single tax return (SC1040 Individual Income Tax Return). Participants are limited to individuals, trusts or estates who are partners of the Partnership, shareholders of the S Corporation or members of an LLC taxed as an S Corporation or Partnership.
A composite return is filed using an SC1040 SC Individual Income Tax Return. The heading states the name, address, and FEIN of the Partnership, S Corporation or LLC. Do not use "Composite Return for" or "Shareholders/Partners of" in the name. Mark the box for filing a Composite Return. Mark Single filing status.
NOTE: Corporate partners and members may not participate in composite returns.
A partnership, S Corporation, or LLC taxed as a Partnership or S Corporation computes the tax separately on each participant's share of income. The methods available for computing the tax depend on whether the partner, shareholder, or member has filed an I-338 Composite Return Affidavit with the SCDOR through the Partnership, S Corporation, or LLC. An I-338 affidavit states that the partner, shareholder, or member has no other income taxable to South Carolina. The tax amounts computed for each participant in the composite return are added together to arrive at the total tax due.
Refer to the I-338 and the I-348 for more information.
See SC Code Section 12-6-5030 and SC Revenue Procedure 17-2.
File the SC4868 to extend the time to file a composite return. Do not use the SC1120T or the federal form 7004. Extending the time to file a composite return does not extend the time to file the South Carolina S corporation (SC1120S) or partnership (SC1065) return.
Any tax estimated to be due must be paid with the timely filed extension.
Request your extension to file by paying your balance due on our free tax portal, MyDORWAY, at dor.sc.gov/pay. Select Individual Income Tax Payment to get started. Your payment on MyDORWAY automatically submits your filing extension request. No additional form or paperwork is required. If filing the SC4868 by paper, mark the Composite Filer box and mail the original with payment, if any.
A consolidated return may be filed on behalf of:
Substantial control means ownership by one corporation of 80% or more of the total combined voting power of all classes of stock of the other corporations. Check the Consolidated Return box on SC1120 and complete Schedule J and Schedule M.
All corporations included in a consolidated return or combined return must use the same accounting year. An election to file a consolidated return must be made on an original, timely filed return. The election to file a consolidated return may not be changed after the return is filed. A multi-state corporation must compute and use a separate apportionment ratio in arriving at the SC taxable income and License Fee for each entity included in the consolidation.
S Corporations, Savings and Loans, and Banks are unable to participate in a consolidated return.
No. Corporations filing a consolidated return should file a single South Carolina extension. There is no extension for payment of Corporate Income Tax or License Fee. Any Income Tax or License Fee due must be paid by the prescribed due date to avoid the assessment of late penalties and interest. File the extension using the FEIN and name of the entity that will be filing the Corporate Tax return.
No. S Corporations, Savings and Loans, and Banks are unable to participate in a consolidated return.
Schedule L is used for disregarded Limited Liability Companies (LLCs) and Qualified Subchapter S Subsidiaries (Q-Subs) included in the Corporate Tax return doing business in South Carolina. Companies doing business in South Carolina may receive a Failure to File notice if they are not included on the Schedule L.
A consolidated return must include the income allocated to South Carolina and the calculation of a separate License Fee for the parent and each subsidiary. A separate annual report and profit-and-loss statement are also required using each member's own apportionment ratio.
The Schedule M is in 3 parts:
No. A corporation cannot file an amended consolidated return to include a corporation that was not included in the original return. The election to be included in a consolidated return must be made on the timely filed original return.
Yes.
If you owe $15,000 or more in connection with any SCDOR return, you must file and pay electronically according to SC Code Section 12-54-250.
Yes.
Yes. Penalty and interest will be applied as permitted by law. A penalty of $500 per period will be assessed until you start filing and paying electronically.

Use the SC1120T to request an extension of time to file a Corporate Tax return.
Save time and paper! Request your extension to file by paying your balance due on our free tax portal, MyDORWAY. Select Business Income Tax Payment to get started. Your payment on MyDORWAY automatically submits your filing extension request. No additional form or paperwork is required.
An extension of time for filing does not extend the time for paying Corporate Income Tax or License Fee. Underpayment penalties and interest will apply if 90% of the Income Tax and License Fee is not paid by the original due date of the return.
When filing your Corporate Tax Return, check the Extension box to indicate you filed a federal or state extension.
No. An extension of time for filing does not extend the time for paying Corporate Income Tax or License Fee. Underpayment penalties and interest will apply if 90% of the Income Tax and License Fee is not paid by the original due date of the return.
Yes. The federal extension will be accepted as a South Carolina extension if the corporate return is received within the time as extended by the IRS.
Yes. Taxpayers can file their South Carolina 1120/1120S (along with their federal Corporate Tax Returns) electronically in a single transmission using third party tax preparation software. Visit dor.sc.gov/biz-services for more information on developers that support corporate electronic filing.
Corporations can pay Income Tax, Estimated Income Tax, and License Fee payments online using our free tax portal, MyDORWAY. Select Business Income Tax Payment to get started.
Corporations can also pay Income Tax, Estimated Income Tax, and License Fee payments electronically through Electronic Funds Transfer (EFT). To get started, the company must register with the SCDOR. For questions regarding EFT, please contact BusinessEFT@dor.sc.gov.Your FEIN (Federal Employer Identification Number) is required to ensure proper credit of returns filed and payments submitted. Providing an incorrect FEIN will result in processing delays and errors in posting the return and payments.
Use our free online tax portal, MyDORWAY, to:
Visit dor.sc.gov/pay and select Business Income Tax Payment to get started. If you make your payment online, no additional form or paperwork is required.
Yes. You must submit the CL-1 and a $25 License Fee to the Secretary of State (SCSOS) if you are a domestic corporation filing your initial Articles of Incorporation or a foreign corporation filing an Application for Certificate of Authority to Transact Business in South Carolina. Make all payments payable to the SCSOS. The SCSOS cannot process a CL-1 that is not accompanied by Articles of Incorporation or an Application for Certificate of Authority to Transact Business.
If you have not already submitted a CL-1 and $25 License Fee to the SCSOS, mail the CL-1 to the SCDOR within 60 days after commencing business in South Carolina or using a portion of total capital in the state. Make your check payable to the SCDOR and mail to:
SCDOR
License & Registration
PO Box 125
Columbia, SC 29214-0850.
The $25 License Fee must be paid at the time the CL-1 is filed.
Interest is due at the prevailing federal interest rate if this return is not filed within 60 days after commencing business in South Carolina.
If you file the return late, you will receive a penalty of 5% per month, not to exceed 25%. If you pay the License Fee late, you will receive a penalty of 0.5% per month, not to exceed 25%.
Insurance agencies file their South Carolina Income Tax return with the SCDOR.
Yes. If your corporation is dormant or you do not have any income or business to report in an accounting period, you are still required to file a Corporate Tax return, including the annual report (Schedule D; which is part of the Corporate Tax return) and pay any tax or License Fee due each year by the due date of your return. There is a minimum $25 License Fee due annually.
If you do not have any income or business activity, a South Carolina Corporate Tax Return is still required to be filed from the date the charter/authority is granted with the South Carolina Secretary of State (SCSOS) through the date of voluntary dissolution/withdrawal recorded with the SCSOS.
If you have discontinued your business, it is necessary to file the dissolution papers (domestic corporations) or withdrawal documents (foreign corporations) with the SCSOS.
A short period return will be required if the corporation registers before the fifteenth day of the month. Other reasons for a short period return include: new corporation filing, accounting period change, or for a corporation that has dissolved.
Failure to file all returns can result in your account being forfeited by the SCSOS.
If you dissolved or withdrew your charter with the SCSOS after your accounting period has ended, you must file a final return.
Example: If you closed your business March 15 and your accounting period is December, you must file a short period return from January 1 through March 15. A License Fee is not generally required on final returns since the License Fee is paid a year in advance. See SC Code Section 12-20-80.
Instructions for dissolution, merging, or authorization for withdrawal are available from the SCSOS online or at 803-734-2158.
If you have discontinued your business, the SCDOR will close your corporate account. File a final Corporate Tax return with an Income Tax period end matching the stamped recorded dissolution date received from the SCSOS. A domestic corporation remains in business until it closes its account with the SCSOS, and a foreign corporation may not withdraw from the State until it obtains a certificate of withdrawal from the SCSOS. See SC Code Sections 33-14-103 and 33-15-200 for more information.
Check the Merged box on the return if you merged with another entity. You must file Articles of Merger with the SCSOS.
Check the Reorganized box on the return if you are reorganizing the corporation:
Check the Final box on the return if this is the corporation's final return. A domestic corporation must file Articles of Dissolution with the SCSOS in order to close the business. A foreign corporation must file an Application for Surrender of Authority to do Business with the SCSOS in order to withdraw from South Carolina. Do not file the final return with SCDOR until the corporation has been dissolved or withdrawn with the SCSOS.
No. If you have discontinued your business, a final return cannot be accepted as such until the proper dissolution papers (for domestic corporations) or withdrawal documents (for foreign corporations) have been completed and filed with the SCSOS. You may contact them at 803-734-2158 for more information.
Homeowners’ Associations are required to file a CL-1 but are exempt from paying the $25 fee.
If the homeowners’ association files a Federal 1120-H with the IRS, they do not file with SCDOR unless they have taxable income to report. If they choose not to file or do not qualify for the 1120H, they are required to file an SC1120 and pay the License Fee.
You will need to report unrelated tax on the SC1120.
If a corporation fails to pay any tax on or before the original due date of the return, a failure to pay penalty must be added to the tax. The penalty will be one-half of one percent of the amount of the tax if the failure is for not more than one month, with an additional one-half of one percent for each additional month or fraction thereof during which the failure continues, not exceeding twenty-five percent.
A corporation that does not file its tax return by the original due date, may be penalized 5% of the unpaid tax for each month the return is late, up to a maximum of 25% of the unpaid tax.
The License Fee rate is 0.1% of the corporation's capital stock and paid-in surplus plus $15. The minimum License Fee is $25.
Generally, every domestic corporation, every foreign corporation qualified to do business in South Carolina, and any other corporation required by SC Code Section 12-6-4910 to file an Income Tax return must file an annual report and pay a License Fee to the SCDOR.
The following organizations, companies, and associations are not subject to the annual report or the License Fee:
See SC Revenue Ruling #05-11 for more information.
The License Fee is due to the SCDOR by the original due date of the return or request for extension. The License Fee period is one year ahead of the Income Tax period. For instance, if the Income Tax period ends December 31 of the current year, the License Fee period ends December 31 of the following year.
Take the original amount of the License Fee (capital x .001 + $15), divide the calculated fee by 12 and then multiply the amount by the number of months in the short period return. Each part of a month is considered a full month. (i.e., the License Fee is not computed based on the number of days in a short period.) Any prorated License Fee may not be less than $25.
A corporation may prorate the License Fee when there is a change in accounting period and a return of less than 12 months is required. This proration applies only to short periods due to a change in accounting period and does not apply to short periods due to initial or final returns. Any prorated License Fee may not be less than $25.
No.
A person may organize a domestic LLC by filing the Articles of Organization with the South Carolina Secretary of State (SCSOS). A person may qualify a foreign LLC to do business in South Carolina by filing an Application for Certificate of Authority to Transact Business with the SCSOS.
Yes, an LLC must file a CL-1 when they elect to be treated as a corporation for tax purposes.
An LLC must file an SC1120 or SC1120S when they elect to be treated as a corporation for tax purposes.
You are exempt from filing and paying taxes only if you are granted a 501(C) status from the IRS. Otherwise, you are required to file and pay taxes. If you are an exempt organization and have unrelated business income, you are required to file an SC990T to report the income.
Apply through the IRS to be granted 501(C) nonprofit status. Mail a copy of the IRS letter to the SCDOR for documentation purposes.
Learn more about tax exempt organizations.
Use Form SC2848.
Use SC2848 to grant authority to an individual to represent you before the SCDOR and to receive tax information. See the instructions for Part I, line 4 for limitations that may apply for certain representatives.
This power of attorney authorizes the individuals named to perform any and all acts you can perform, such as signing consents extending the time to assess tax, recording the interview, or executing waivers agreeing to a tax adjustment. Authorizing someone as your power of attorney does not relieve you of your tax obligations. Delegating authority or substituting another representative must be specifically stated on line 4; however, the authority granted to a power of attorney may not exceed that allowed under SC Code Section 12-60-90. See South Carolina Revenue Procedures 92-4 and 92-6. The power to sign tax returns can only be granted in limited situations. See Line 4 - Acts Authorized for more information.
Federal Form 2848 may be substituted for SC2848 even though the instructions for the two forms differ somewhat. Be sure to note the differences and complete the Federal Form 2848 accordingly.
No. Only the parent corporation’s information is required on line 1; however, a subsidiary must file its own SC2848 for returns that are required to be filed separately from the consolidated return.
You must enter the type of tax, the tax form number, and the years or periods in order for the power of attorney to be valid. For example, you may list Corporate Income Tax, SC1120 for calendar year 2020.
A general reference to "All years," "All periods," or "All taxes" is not acceptable. The SCDOR will not accept a power of attorney with a general reference. You may list the current year/period and any tax years or periods that have already ended as of the date you sign the power of attorney.
You may include on a power of attorney only future tax periods that end no later than three years after the power of attorney is received by the SCDOR. The three future periods are determined starting after December 31 of the year the power of attorney is received by the SCDOR. You must enter the type of tax, the tax form number, and the future years or periods.
In order to obtain Corporate Tax information using an SC2848, an officer of the corporation must sign the power of attorney form and the officer listed must be verified on the latest return filed by the corporation. If the officer signing on behalf of the corporation is not verified on the latest Corporate Tax return, a copy of the minutes showing election of the officer and their position must be presented to the SCDOR. Power of Attorney forms and information pertaining to them may be mailed.
Yes. A Power of Attorney (POA) gives the SCDOR the authority to speak to a representative of the corporation or accounting firm about their account. The SC2848 should be signed by a verifiable officer listed on Schedule D of the Corporate Tax return.
