Retirement Stacking: Supercharging Your Future Tax Savings

Saving for retirement is smart. But with the right strategy, you can stack multiple retirement plans for even bigger tax advantages.


Common Tools:

  • Solo 401(k): For self-employed and small business owners. Allows high contributions (employee + employer portions).
  • SEP-IRA: Flexible for businesses with variable income.
  • Cash Balance Plans: Great for high earners—combine with 401(k) to supercharge savings.


Example for High Earners:

  • Solo 401(k) contribution limit (2025): Up to $69,000 with catch-up contributions.
  • Add a Cash Balance Plan: Potentially save $100,000+ per year while reducing taxable income.


Benefits of Stacking:

  • Massive tax deferral (pay less now, save more for later).
  • Accelerates retirement savings.
  • Creates a strong shield against unpredictable tax law changes.

Who Should Consider This:

  • High-income business owners.
  • Professionals nearing retirement who want to catch up.
  • Companies with stable cash flow looking to reward owners and key employees.



👉 Pro Tip: Work with a CPA or financial advisor—stacking has rules, but done right, it’s one of the most powerful wealth-building tools.
