Business Retirement Plan Advisory
Employer Retirement Plan Advisory
Choosing and managing a retirement plan for your employees is one of the more consequential decisions a business owner makes, and one of the easiest to get wrong without the right help. Oak Street Advisors works with small and mid-sized businesses in Myrtle Beach, Charleston, and across South Carolina to design, implement, and monitor employer retirement plans that work for both the business and the people in it.
We act as a co-fiduciary alongside your plan sponsor, which means we share legal responsibility for acting in your employees’ best interest, not just offering recommendations from the sidelines. We also partner with independent third-party plan administrators to provide a turnkey solution, so you’re not left coordinating multiple vendors on your own.
Retirement Plan Options We Help You Compare
Not every business needs the same kind of plan. We help you weigh the options based on your business size, budget, and goals for both yourself and your employees.
401(k) Plans: The most flexible option for businesses that want higher contribution limits and features like employee loans and Roth deferrals. In 2026, employees can defer up to $24,500, with an additional $8,000 catch-up contribution for those 50 and older.
SIMPLE IRA: A lower-cost, lower-administration option for businesses with 100 or fewer employees. SIMPLE IRAs require an employer match or contribution but come with far less paperwork than a traditional 401(k), making them a popular starting point for smaller businesses.
SEP IRA: Best suited for businesses with few or no employees, including sole proprietors. Contributions are employer-funded only, up to 25% of compensation or $72,000 in 2026, whichever is less. SEP IRAs are simple to set up and maintain, with no annual filing requirements.
Safe Harbor 401(k): Designed for business owners who want to maximize their own contributions without the complexity of annual nondiscrimination testing. In exchange for guaranteeing a minimum employer contribution or match, the plan is automatically considered compliant.
We’ll help you weigh the tradeoffs between cost, administrative complexity, and contribution limits to find the plan that actually fits your business, not just the one that’s easiest to set up.
How It Works
- Initial Plan Review We start by reviewing your current plan (if you have one) or your goals for a new plan, including your budget, employee census, and what you’re trying to accomplish.
- Plan Comparison We compare your options across cost, plan type, and investment menu, showing you clearly how your current plan stacks up against the alternatives.
- Implementation Once you’ve chosen a direction, we coordinate with a third-party plan administrator to get the plan set up and ready for enrollment, handling the logistics so you don’t have to.
- Ongoing Monitoring We continue to monitor plan investments and fees, provide annual education meetings for your employees, and stay available as your business and its needs evolve.
