Roth IRAs are a type of individual retirement account (IRA) that provide tax-free growth and withdrawal opportunities in retirement. However, there are several synonyms and similar types of retirement accounts that investors should be aware of. These include traditional IRAs, which offer tax-deferred contributions but taxable withdrawals, and SEP IRAs, which are designed for self-employed individuals and small business owners. Additionally, some employers offer Roth 401(k) plans, which have similar tax benefits to Roth IRAs but with higher contribution limits. It is important to research and consider all options when choosing a retirement account to ensure it aligns with your financial goals and needs.
