Roth TSP and Roth IRA » are both excellent post-tax retirement savings options, but they have key differences that federal employees should understand. The Roth TSP, part of the Thrift Savings Plan, offers higher contribution limits and potential employer matching, making it ideal for maximizing retirement savings. The Roth IRA, while providing more investment options and tax-free growth, has lower contribution limits and no matching contributions. Federal Pension Advisors can help federal employees navigate these choices, offering expert guidance to select the plan that best fits their financial goals and long-term retirement strategy.
