Flat-fee, retirement plans for business owners (SEP, solo 401k) financial advisors in Rapid City, SD
The right financial advisor for you depends on how you weigh location, expertise, experience, the clients they typically serve, and how they work with you.
If you run a business and want to set up a retirement plan like a SEP or solo 401(k), you need an advisor who understands how these plans fit your unique cash flow and tax situation. A common mistake is choosing a plan without considering how fees and plan features affect your long-term savings.
- Flat-fee clarity. Confirm how the advisor charges you to avoid surprises and ensure fees align with your plan's complexity.
- Plan selection insight. Ask why they recommend a SEP versus a solo 401(k) based on your business size, income, and growth plans.
- Federal tax focus. Since South Dakota has no state income tax, check how they optimize your retirement plan for federal taxes and other local taxes like sales and property.
- Business cash flow integration. See how they balance retirement contributions with your business’s ongoing expenses and growth needs.

We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
