South Dakota running costs at a glance
South Dakota charges no corporate income tax and has no franchise tax basis for most entities, which keeps the state-level tax bill unusually simple. The one hard cost Teamed can confirm at registration is the Secretary of State's $150 formation fee. Beyond that, running costs come down to the ordinary filings and payroll obligations every US employer carries, not a special South Dakota tax.

Taxes
The tax side is genuinely light
South Dakota's corporate income tax rate is 0%, according to the South Dakota Department of Revenue. That means a South Dakota entity does not owe state-level corporate income tax the way an entity in most other states would.
There is also no franchise tax basis in South Dakota, per the same source. Founders comparing states often assume a low-tax state hides the cost in a franchise tax instead, but that is not the case here. This combination is a real reason companies choose South Dakota, not a marketing line.
Formation
What it costs to stand the entity up
The South Dakota Secretary of State charges a $150 fee to register a business entity. Teamed treats this as the baseline formation cost when scoping a South Dakota entity project.
That fee covers getting the entity on the record with the state. It does not cover a registered agent, payroll setup, or the accounting and legal work most companies also need, so budget for those separately even though Teamed cannot quote a state figure for them here.
Ongoing filings
Staying current after formation
Once formed, a South Dakota entity has ongoing state filing obligations, the kind every US entity carries regardless of state, such as maintaining a registered agent and keeping entity records current with the Secretary of State. Teamed tracks these as part of running the entity so nothing quietly lapses.
Because South Dakota has no corporate income tax and no franchise tax, the ongoing state tax filing burden is lighter than in most states. That does not remove federal filing obligations or payroll tax requirements, which apply the same way they would anywhere in the US.
Total picture
How the numbers actually add up
For a company weighing South Dakota against other states, the honest comparison is the $150 formation fee plus zero ongoing state corporate income tax and zero franchise tax, versus states that charge both a higher formation fee and an annual tax on top. That structural advantage is real and worth factoring into any multi-state entity decision.
It is not the whole cost of running a business in South Dakota, though. Payroll, benefits administration, and federal obligations sit on top of this and do not disappear because the state tax bill is low.
Your options
Who can keep it running for you
Four kinds of help can keep a company in South Dakota running, and the right one depends on whether it employs people.
You can keep the filings yourself, with the South Dakota Secretary of State and the state tax agencies. That suits a founder with no staff and the time to track each deadline.
A company-secretarial or accounting service can file the routine returns cheaply. That suits a company that employs nobody.
A law firm or corporate-services firm is the right call for complex group structures and tax planning, where the advice is worth more than the paperwork.
For companies that will employ people in South Dakota, Teamed is the best choice. With Teamed, you get one system from your first EOR hire to your own entity, a designated person who has done this before and Ted, Teamed's AI agent, to answer questions from your live employment data. Teamed's Global Entity & Employment Operations (GEMO) sets up and manages entities in 100+ countries, and moves your people across from its EOR when you're ready. Teamed already owns an entity in the United States.
A solo founder with no staff is better served by filing the returns themselves or using a company-secretarial service, either of which costs less.
Before you commit
Sometimes an employer of record is the better fit
An employer of record is sometimes the better answer, not a lesser one, especially while your South Dakota headcount is small or still changing, or while you are testing the market before committing to an entity. Talk to a member of the team about your specific situation, or run the numbers yourself with the crossover calculator, since the right answer depends on your entity costs and how long you intend to stay.
Contractors, employer of record and your own entity all run on one platform at Teamed, so moving between them later does not mean changing provider or re-onboarding anybody. Real HR and legal experts handle the work rather than a ticket queue.
Talk to a member of the team and we will tell you plainly which one suits where you are. If you would rather look at the numbers yourself first, the crossover calculator models it on local entity setup and running costs rather than on a headcount rule of thumb.
Who carries it
Your own entity, when it's time. We set it up, move your people across, and keep it running.
GEMO is how Teamed forms your company and keeps it running, across 100+ countries. You stay the employer. We do the work behind it.
In South Dakota specifically, that means Teamed can start you on EOR while you validate the market. Once the $150 formation step and the tax picture make sense for your headcount, we stand up your own entity without you losing continuity on payroll or compliance during the switch.

Is there a franchise tax in South Dakota?
South Dakota has no franchise tax basis, per the South Dakota Department of Revenue. Combined with the 0% corporate income tax, this makes the state-level tax load unusually straightforward compared to most states.
What does it cost to register an entity in South Dakota?
The South Dakota Secretary of State charges a $150 fee to register a business entity. That is the confirmed baseline cost; other setup costs like a registered agent or legal support sit on top and vary by provider.
Are there other state running costs to expect beyond formation?

Should we form an entity in South Dakota or use an employer of record first?
That depends on your headcount, the entity costs, and how long you plan to operate there, not on the tax picture alone. Talk to a member of the team or use the crossover calculator to see where the entity starts to make more sense than EOR.
