South Carolina State Tax Extensions: Business, Personal, Information and Nonprofit Tax Returns

Which form is used to file for extension?

If any corporate income tax or license fee is anticipated to be due, the taxpayer must use South Carolina extension SC1120-T or file electronically at www.sctax.org under DORePAY. If no income tax or license fee is anticipated to be due and the taxpayer has requested a federal extension, the federal extension will be accepted as a South Carolina extension if the corporate return is received within the time as extended by the Internal Revenue Service.

An extension of time to file SC1120 does not extend the Business Personal Property Return. File PT-100 separately.Corporations filing a consolidated return should file a single South Carolina extension and attach a schedule listing the corporations to be included in the South Carolina consolidation. A federal extension will be accepted if all corporations filing in South Carolina are included in one or more federal extensions.

How to File?

For South Carolina Income Tax purposes a consolidated return shall mean a single return for two or more corporations in which income or loss and license fee is computed separately for each corporation and combined into one return. All corporations included in the consolidated return must be subject to tax in South Carolina and have the same accounting year.

The election to file a consolidated return must be made on an original and timely filed return. Once an election is made, such election must be adhered to until permission is granted by the SC Department of Revenue to file a separate return. If a corporation substantially understates its tax, it will be charged a substantial understatement penalty of twenty-five percent of the understatement. A substantial understatement is the greater of ten percent of the tax liability or ten thousand dollars.

In the case of an S Corporation or a personal holding company a substantial understatement is the greater of five thousand dollars or ten percent of the tax liability.These corporations must also be substantially under the control of the same interest. "Substantial control" means the ownership of at least eighty percent of all classes of stock. A domestic or multi-state corporation can file a consolidated return. You must compute the income and license fee separately for each entity included in the consolidation.

A schedule must also be attached listing the corporations included in the South Carolina consolidation.A copy of the federal or South Carolina extension(s) must be attached to the return when filed.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.

An extension of time to file SC1120 does not extend the Business Personal Property Return. File PT-100 separately.

What are the penalties and Interest?

Avoid penalties and interest by correctly filing and paying the tax when due.A corporation is required under Code Section 12-54-210 to keep books, papers, memorandum, records, render statements, make returns and comply with regulations as the department prescribes. If a Corporation fails to comply with the provisions of this section, a failure to comply penalty must be added not to exceed five hundred dollars for the period covered by the return in addition to other penalties provided by law.

If a corporation fails to file its tax return when due (including any extensions of time for filing), it may be subject to a failure to file penalty. The penalty shall be five percent of the amount of the tax due if failure is for not more than one month, with an additional five percent for each additional month or fraction thereof during which the failure continues, not exceeding twenty-five percent in the aggregate. The penalty is calculated on the amount of tax shown due on the return reduced by any amounts paid on or before the date prescribed for payment of the tax. In any event, the SC Department of Revenue may assess a late filing penalty of up to $500.00 in addition to the above specified late filing penalties.

If a corporation fails to pay any tax on or before the due date, a failure to pay penalty must be added to the tax. The penalty shall 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.

If a corporation underpays its tax liability and the underpayment is due to negligence or disregard of regulations, it will be charged a negligence penalty of five percent of the underpayment plus fifty percent of the interest payable.

If a corporation substantially understates its tax, it will be charged a substantial understatement penalty of twenty-five percent of the understatement. A substantial understatement is the greater of ten percent of the tax liability or ten thousand dollars. In the case of an S Corporation or a personal holding company a substantial understatement is the greater of five thousand dollars or ten percent of the tax liability.

If a corporation fails to remit the tax due it will be charged interest at the rate provided under

Internal Revenue Code Sections 6621 and 6622. The interest must be calculated on the full amount of tax or portion thereof, exclusive of penalties, from the time the tax was due until paid in its entirety.

If the taxpayer does not request additional time for filing his federal tax return but needs further time to file his South Carolina return, he may file a federal Form 2688 with the SC Department of Revenue or otherwise request such an extension in writing at the address shown on the front of this form.

If the taxpayer filed a SC4868 and requested an extension period of less than six months, he may subsequently request in writing the additional time which added to the original request will equal six months, and will automatically be granted.

When to File?

Interest and Penalty for failure to pay tax:

The extension of time to file your South Carolina tax return granted by this application DOES NOT extend the time for payment of tax . Any unpaid portion of the final tax due will bear interest at the prevailing federal rates.This amount is computed from the original due date of the tax return to the date of payment. In addition to the interest, a penalty at the rate of 1/2% per month to maximum of 25% must be added when the amount remitted with the extension fails to reflect at least 90% of the tax due by April 15, 2025. The penalty will be imposed on the difference between the amount remitted with the extension and the tax to be paid for the period.
