South Dakota Annual Report Filing Requirements for LLCs and Corporations

Keeping a South Dakota business in good standing requires more than forming the entity and opening for business. In most cases, you also need to file an annual report with the South Dakota Secretary of State each year. Missing that filing can trigger late fees, delinquent status, and, eventually, administrative dissolution or revocation.

This guide breaks down the South Dakota annual report filing requirements, including who must file, when the report is due, what it costs, what information you need, and what happens if you fall behind.

What Is a South Dakota Annual Report?

A South Dakota annual report is a recurring state filing that confirms your business entity is still active and that the state’s records are current. It helps the Secretary of State keep track of your business address, registered agent, and key company contacts.

The annual report is not the same thing as a tax return. It is a compliance filing that keeps your entity in good standing with the state.

Who Has to File an Annual Report?

Most active business entities registered in South Dakota must file an annual report every year. That includes common business structures such as:

• LLCs
• Corporations
• LLPs
• Certain other registered business entities

Some entities are excluded from the annual report requirement. For example, limited partnerships and business trusts are not required to file annual reports in South Dakota.

If you are not sure whether your entity must file, check your registration status in the Secretary of State’s business records before assuming you are exempt.

When Is the South Dakota Annual Report Due?

South Dakota annual reports are due on the first day of the anniversary month of the date your business was filed with the Secretary of State.

That means the due date is tied to the month your entity was formed, not to a calendar year-end or a tax deadline.

Example

If your LLC or corporation was filed on July 20, 2025, the annual report would be due on July 1, 2026, and every July 1 after that.

Filing Window

You do not need to wait until the due date. South Dakota allows you to file the annual report up to two months before it is due.

That early filing window is useful if you want to get compliance out of the way before your busiest season.

Delinquency Timeline

If the report is not filed by the due date, the entity does not become delinquent immediately. Delinquency and late fees begin two months after the due date.

Using the same July 1 example, delinquency would begin on September 1 if the report still had not been filed.

How Much Does It Cost?

Annual report fees in South Dakota depend on both the entity type and the filing method.

For many LLCs and corporations, the current fee schedule is:

• $55 if filed electronically
• $70 if filed by paper

The paper filing price includes an additional paper processing fee.

There is also a $50 late fee for annual reports filed after the delinquency date.

Some entity types have different annual report pricing. For example, nonprofits have their own filing treatment, and certain entities may be exempt from the extra late fee even though they still must file.

Because fees can change, it is smart to confirm the current amount before submitting your filing.

What Information Do You Need to File?

Before you start, gather the information the state expects to see on the annual report. The exact details can vary slightly by entity type, but the filing commonly asks for:

• Business ID
• Legal business name
• Principal business address
• Mailing address, if different
• Registered agent name
• Registered agent address
• Names and addresses of officers, directors, governors, members, or partners, depending on the entity type
• Email address, if requested or allowed

For LLCs and corporations, the annual report is essentially a current snapshot of the company’s official records. If your registered agent, address, or leadership has changed, the report is the place to make sure the state has the right information.

How to File a South Dakota Annual Report

South Dakota allows annual reports to be filed online or by paper.

Online Filing

Online filing is the fastest option and usually the cleanest path for most businesses. Once submitted, you typically receive immediate confirmation and a downloadable receipt.

Online filing is also the better choice if you want to avoid paper-processing delays.

Paper Filing

Paper filing is still available, but it usually costs more and takes longer to process. If your business could have filed online but chooses paper instead, the filing may include an extra paper fee.

Basic Filing Steps

1. Locate your business record or Business ID.
2. Review your entity information for accuracy.
3. Confirm your registered agent and address details.
4. Enter the annual report information.
5. Pay the filing fee.
6. Save the confirmation for your records.

If your company has changed addresses, officers, or registered agent information, fix those issues before or during the report process so your state records stay current.

What Happens If You Miss the Deadline?

Missing the due date does not end your business, but it can create a compliance problem quickly.

If you do not file by the delinquency date, South Dakota can assess late fees and mark the entity as delinquent. If the business remains delinquent long enough, it may be administratively dissolved or revoked.

That matters because a dissolved or revoked entity can lose good standing, which may affect the ability to:

• Enter into contracts
• Open or maintain business bank accounts
• Secure financing
• Register in other states
• Keep a clean compliance record

If your business has already fallen out of good standing, you may need to file past-due annual reports and complete a reinstatement process before the entity is active again.

How to Avoid Annual Report Problems

Annual report compliance is usually simple, but only if you stay ahead of the deadline. A few practical habits can prevent most issues:

• Put the due date on a recurring calendar reminder
• Store your Business ID in an accessible compliance file
• Keep registered agent details current throughout the year
• Review ownership and officer changes as they happen
• File early if your business has seasonal downtime
• Use a compliance system so deadlines do not depend on memory alone

For business owners managing multiple entities, the risk is not complexity. It is volume. Once you have more than one filing deadline, missed dates become much more likely unless someone owns the process.

Where Zenind Fits In

Zenind helps business owners stay organized after formation by making compliance easier to manage. For South Dakota companies, that can mean keeping track of annual report deadlines, maintaining up-to-date entity information, and reducing the chance of avoidable late fees.

If you want to spend less time tracking state deadlines and more time running the business, a compliance workflow can save both stress and money.
