South Dakota has no personal or corporate income tax, which attracts out-of-state founders forming LLCs here for tax advantages. That also means your registered agent's address is one of the few pieces of public information the state ties to your LLC. Since South Dakota does not offer anonymous LLCs, using a commercial agent instead of your home address is the simplest way to keep your personal details off the Secretary of State's public database.

Northwest Registered Agent is our top recommendation for privacy-minded founders. They shield your home address on public records and process legal mail the same day it arrives. The initial cost is slightly higher than free competitors, but the stable $125 renewal rate saves you money long-term. We highly recommend them if you want reliable compliance without the endless upsell pitches.
