South Carolina Annual Report Rules: Which Business Entities File in 2026?
South Carolina Annual Report Rules: Which Business Entities File in 2026?
South Carolina is one of the easiest states to misunderstand if you search only for the phrase “annual report.”
That is because South Carolina does not present one simple Secretary of State annual-report system for every business entity. Instead, the official rules split depending on entity type and, in some cases, tax classification.
The South Carolina Department of Revenue says C corporations must file the SC 1120 annually, and that return includes the annual report (Schedule D) and payment of the license fee. The DOR also says S corporations must file an Initial Annual Report of Corporations (CL-1) and pay a one-time $25 initial corporate license fee within 60 days of doing business or using capital in South Carolina, if that fee was not already paid to the Secretary of State.
That means the first South Carolina question in 2026 is:
What kind of entity are you really dealing with?
For corporations, South Carolina ties annual reporting to tax filings
The Department of Revenue’s C corporation page says:
- C corporations must file the SC 1120 annually;
- the return includes the annual report (Schedule D); and
- the return also includes payment of the license fee.
The DOR says the return and payment are due by the 15th day of the fourth month after the close of the taxable year.
For a calendar-year corporation, that usually means a mid-April deadline.
South Carolina’s official annual report form language
South Carolina’s official SC 1120 form includes a Schedule D labeled:
- Annual Report to be completed by all corporations
That is the clearest official wording in the state materials. In South Carolina, “annual report” is often part of the corporate tax-return workflow rather than a standalone business-entity filing page for every type of company.
S corporations have an initial reporting step too
The DOR’s S corporation guidance says businesses are required to file an Initial Annual Report of Corporations (CL-1) and pay a one-time $25 initial corporate license fee within 60 days of doing business or using capital in the state, if it was not already paid to the South Carolina Secretary of State.
After that, the corporate tax filing system becomes part of the ongoing compliance picture.
Why LLC owners get confused
Many South Carolina business owners operate through LLCs, not corporations.
But the official materials we could verify for annual reporting point directly to:
- corporate returns with Schedule D annual reports; and
- the CL-1 initial corporate reporting framework.
That means an LLC owner should not assume the same annual-report rule applies automatically. The safer approach is to check whether the LLC is being treated under a corporate tax framework or whether the company’s recurring state obligations mostly live elsewhere, such as entity-maintenance filings, registered-agent updates, and tax accounts.
The Secretary of State online system still matters
Even when a business does not use a classic annual-report filing path with the Secretary of State, South Carolina’s Business Entities Online system still matters.
The Secretary of State says users may:
- file organizing documents online;
- file documents for existing entities;
- search entities on file; and
- view registered-agent and registered-office information.
So even if annual reporting is being handled through the Department of Revenue for a corporation, entity-maintenance work still depends on the Secretary of State record being accurate.
Why registered-agent accuracy still matters
South Carolina’s online business-entities system allows users to search existing entities and registered-agent information.
That means the registered-agent record remains a core part of compliance even when the “annual report” function itself is handled through a tax return.
This is especially important for businesses that:
- changed offices;
- changed professional service providers;
- converted tax treatment;
- or have more than one state on their compliance calendar.
Practical South Carolina compliance checklist for 2026

- [ ] Review the Secretary of State business-entity record and registered-agent information.
- [ ] Use the South Carolina online systems for both tax and entity maintenance as needed.
FAQ
Which South Carolina entities clearly file an annual report in 2026 based on official sources?
The official sources we verified clearly tie annual reporting to corporations, especially through the SC 1120 and Schedule D annual report process for C corporations.
What is Schedule D in South Carolina?
The official SC 1120 form labels Schedule D as the annual report to be completed by all corporations.
When is the South Carolina C corporation filing due?
The Department of Revenue says the return and payment are due by the 15th day of the fourth month after the close of the taxable year.
What is CL-1 in South Carolina?
The DOR’s S corporation guidance says CL-1 is the Initial Annual Report of Corporations, with a one-time $25 initial corporate license fee due within 60 days if it was not already paid to the Secretary of State.
Why should South Carolina businesses still review registered-agent information?
Because the Secretary of State’s online business-entities system is still the official place to search entity and registered-agent records, and stale information can create notice and status problems even if the annual report function is tied to tax filings.
