Mississippi annual report filing requirements

Mississippi annual reports must generally be filed through the Secretary of State's online portal. Per the SOS Business FAQs, all entity types now file these reports online, and the SOS does not publish a standard paper-filing alternative.

Deadlines for filing your Mississippi annual report

• For-profit corporations and LLCs: April 15 (filing opens January 1)

• Nonprofit corporations: May 15

The April 15 deadline for corporations and LLCs is set under Mississippi Code § 79-4-16.22, which requires delivery of the annual report within sixty days of April 15 each year.

Filing fees by entity type

Mississippi's fee schedule creates significant cost differences based on entity type:

Nonprofit and foreign corporation annual report fees should be verified directly with the SOS, as the published fee schedule and the online filing portal can show different amounts for these categories. The SOS has also issued a formal warning about misleading mailers from third-party companies that imply fees are owed for LLC annual reports, which are free.

Consequences of non-compliance

Mississippi does not impose a separate monetary late fee for missing the annual report deadline, but the procedural consequences are significant. For corporations, failing to deliver the annual report within 60 days after it is due is a ground for administrative dissolution under Mississippi Code § 79-4-14.20. LLCs face an equivalent dissolution ground under Miss. Code Ann. § 79-29-821. Before issuing a certificate of dissolution, the SOS must serve the entity with written notice and provide at least a 60-day window to cure the grounds. The notice and cure procedures are set out in § 79-4-14.21 for corporations and § 79-29-823 for LLCs.

While there is no late fee attached to the annual report itself, monetary consequences arise at the reinstatement stage, where filing fees, outstanding tax liabilities, and tax clearance requirements apply.

Administrative dissolution results in:

• Restriction to wind-up and liquidation activities only

• Inability to maintain any action, suit, or proceeding in Mississippi courts until reinstated, as confirmed in Wayne Johnson Electric (Miss. 2019)

• Risk of losing name protection, since another entity may register the same name during the dissolution period

Reinstatement process

To reinstate a dissolved business in Mississippi, you must:

• File all outstanding tax returns and pay all liabilities with the Mississippi Department of Revenue

• Obtain a tax clearance letter through the DOR's TAP online portal

• Submit the reinstatement application through the SOS online portal

Reinstatement fees are form-specific and entity-specific. For common LLC and corporate filings, domestic reinstatement fees cluster around $50 and foreign reinstatement fees around $100, but figures vary by entity type and should be verified against the current SOS fee schedule.

FAQs about filing a Mississippi annual report

Below are answers to the most common questions about Mississippi annual report filings.

Are there monetary late fees for missing the deadline?

Mississippi does not impose a separate monetary late fee on the annual report itself. The consequence of non-filing is administrative dissolution after notice and a cure window, and reinstatement carries its own filing fees and tax clearance requirements.

Are initial reports required when forming a new entity?

No. Mississippi does not require a separate initial report; entities file only annual reports on the standard calendar cycle. Your first annual report is due in the calendar year following formation, on the April 15 or May 15 date that applies to your entity type. An entity formed in December 2025, for example, owes its first annual report by April 15, 2026 (corporations and LLCs) or May 15, 2026 (nonprofits).

Who is authorized to file my Mississippi annual report?

Per the SOS Business FAQs, knowingly signing or authorizing the filing of business entity documents without authority can be a misdemeanor in Mississippi under Miss. Code Ann. § 79-4-1.29 (corporations) and § 79-11-123 (nonprofits). Filings should be submitted by persons authorized to act for the company.

Do nonprofits now have to file annual reports in Mississippi?

Yes. House Bill 1344, effective July 1, 2024, extended the annual report requirement to nonprofit corporations under the Mississippi Nonprofit Corporation Act. The deadline is May 15 each year, and failure to file can result in Mississippi entity administrative dissolution under Miss. Code Ann. § 79-11-349.
