What is the difference between a deferred and an immediate annuity?

The key difference is that a deferred annuity is a long-term vehicle, designed to accumulate assets over time. When you are ready to receive income, usually at retirement, you can convert your savings to a steady stream of income that meets your needs. Immediate annuities are designed to begin making annuity payments right away or within a short time afterward. In addition, deferred annuities may be purchased with a lump sum or multiple contributions. An immediate annuity is usually purchased with a single lump sum contribution.
