Keogh plans, also known as HR10 plans, are tax-advantaged retirement savings plans for self-employed individuals and small business owners. These plans were named after Representative Eugene Keogh, who sponsored legislation in 1962 that allowed self-employed individuals to contribute to retirement plans. While Keogh plans are a popular option for retirement savings, there are also other synonyms for this type of plan. These include Solo 401(k), Self-Employed 401(k), Individual 401(k), or one-participant 401(k). These plans offer similar tax benefits as Keogh plans, but with higher contribution limits and more flexible investment options. Ultimately, the best retirement plan for an individual depends on their specific financial situation and retirement goals.
