A practical course on using after-tax workplace retirement contributions to build Roth savings beyond standard limits.

This course places the Mega Backdoor Roth Strategy in the broader context of Personal Finance and retirement account planning. Students begin with the tax basics behind traditional, Roth, and after-tax contributions, then learn how annual limits, employer contributions, and available plan room shape the real opportunity.

From there, the course walks through the specific plan features required to use the strategy, including how to read a Summary Plan Description and identify whether in-plan Roth conversions or Roth IRA rollovers are available. Students also learn how to calculate contribution capacity, coordinate payroll timing, and set up contributions in a way that aligns with their annual savings plan.

The tax treatment section explains how earnings before conversion are handled, why basis tracking matters, and what records and forms students should understand before executing the strategy. The course also covers common errors, nondiscrimination testing concerns, employer constraints, and suitability considerations for high earners and business owners.

By the end of the course, students will be able to evaluate whether the Mega Backdoor Roth Strategy fits their situation, communicate more confidently with plan administrators and tax professionals, and maintain an annual checklist for building Roth savings with greater clarity and control.
