Short answer
Yes — once your nexus has genuinely ended. Canceling your South Dakota sales tax license makes sense if your gross sales into South Dakota have been below $100,000 in both the current and the immediately preceding calendar year, meaning you no longer meet the economic nexus threshold. The main catch is that you must file and pay all outstanding returns before the cancellation request will be accepted via the MTA portal — missing that step can result in penalties and the license remaining open.

Do you still have nexus in South Dakota?
You can only cancel once your obligation has ended. Two things create it: physical presence (inventory, an employee, an office) and economic nexus (crossing $100,000 in sales).
For Amazon FBA and 3PL sellers the sneaky one is physical nexus: storing inventory in South Dakota creates it. Physical presence including employees, contractors, business property, or inventory stored in the state creates physical nexus from dollar one. If that inventory has since left the state, your physical nexus may have already ended even though the registration is still open.
Trailing nexus in South Dakota
South Dakota does not have an explicitly defined trailing nexus policy. The economic nexus threshold is measured on the 'previous or current calendar year' basis; once a seller no longer meets $100,000 in gross sales in either the current or prior calendar year, nexus ceases and the seller may cancel their license.
Seller must file all outstanding returns before submitting cancellation request. No other explicit restrictions found.
