Among the different types of annuities, a MYGA—or multi-year guaranteed annuity—offers a straightforward way to earn tax-deferred interest at a fixed rate of return over time. Like all annuities, MYGAs are long-term retirement planning tools that can provide a steady, predictable income stream for life, regardless of market fluctuations or longevity. What sets MYGAs apart is their conservative approach, offering predictable investment growth and little risk.
