This state imposes no broad personal income tax on wages or pass-through business income. Other state-level taxes (sales, property, franchise/gross-receipts where applicable) still apply. The absence of a state income tax substantially changes the value of federal-only tax planning moves (S-Corp election, retirement-plan stacking, QBI optimization), because there's no state piggyback to compound the federal benefit.
This state does not currently offer a Pass-Through Entity (PTE) tax election under the post-TCJA state workaround framework. South Dakota has no personal income tax on pass-through business income, so there is no state income tax for a PTE election to convert into a federal business deduction.
This state has not enacted a 1099-K reporting threshold lower than the federal floor. The IRS applies the federal threshold ($20,000 in gross payments AND more than 200 transactions through a third-party settlement organization, as restored by the One Big Beautiful Bill Act, P.L. 119-21, retroactive to 2022). Sellers under that floor will not receive a 1099-K from platforms like PayPal, Venmo Business, eBay, Etsy, or Stripe. Note: receipt of a 1099-K does not change the underlying tax obligation; all business income is reportable regardless of whether a 1099-K is issued.
The state adopted economic-nexus rules following South Dakota v. Wayfair (2018). Remote sellers without physical presence trigger sales-tax collection obligations once they exceed the state's annual gross-receipts or transaction-count threshold, applied to prior or current calendar year. Marketplace facilitators (Amazon, eBay, Etsy, Walmart) collect on behalf of third-party sellers under separate marketplace laws.
South Dakota requires a remote seller to register and collect once its gross sales into South Dakota exceed $100,000 in the previous or current calendar year. The 200-transaction test was repealed effective July 1, 2023 (SB 30), so a transaction count alone no longer creates an obligation (South Dakota Department of Revenue, as of October 2026).
South Dakota LLC formation requires filing Articles of Organization with the South Dakota Secretary of State (filing fee state-specific). Most states require an annual or biennial report filing with a fee. Some impose a franchise-tax minimum on LLCs. Confirm current fees on the South Dakota Secretary of State page.
South Dakota has no personal income tax, so there are no state individual estimated-tax payments and no state safe harbor to meet. A freelancer's quarterly estimates are federal only (IRS Form 1040-ES, due April 15, June 15 and September 15, 2026 and January 15, 2027).
Once the threshold facts are clear, the next question is what they mean for your specific income mix. Use the S-Corp Election Calculator to test whether the salary/distribution split clears the federal break-even given South Dakota rates, the Income Tax Pipeline to model federal + South Dakota liabilities together, and the Reseller Profit Calculator for 1099-K-affected resale operations.
No. South Dakota has not enacted a 1099-K reporting threshold lower than the federal floor. Sellers will receive a 1099-K only if they exceed the federal threshold (the restored federal $20,000 and 200-transaction floor applies). All business income remains reportable on the federal and state return regardless of whether a 1099-K is issued.
No. South Dakota does not currently offer a Pass-Through Entity tax election. South Dakota pass-through owners cannot use a PTE election to convert state income tax into a federal business deduction beyond the federal SALT cap ($40,400 for 2026). Other federal-only planning levers (retirement-plan contributions, QBI optimization, accountable-plan reimbursements) remain available.
Remote sellers without physical presence in South Dakota must register and collect South Dakota sales tax once they exceed the state's annual threshold: more than $100,000 in gross sales in the prior or current calendar year (the 200-transaction test was repealed July 1, 2023). Marketplace facilitators (Amazon, eBay, Etsy, Walmart) collect on behalf of third-party sellers under separate marketplace laws. Verify the current threshold structure against the South Dakota Department of Revenue.
See the LLC formation and annual fees section above for South Dakota's current formation fee, annual report fee, and any franchise-tax minimum applicable to LLCs. Fees and filing requirements vary substantially state-to-state (from under $50/year in some states to $800+/year in others).
What a seller may claim, must disclose, and owes in tax is set by published federal rules rather than by any marketplace's seller handbook, and the sources below are the primary ones. They are linked so a reader can check a claim here without taking this page's word for it.
This page describes tools and the rules that apply to using them. A seller's own structure, state and marketplace agreements decide what applies to them.
