What Is a MYGA? How Multi-Year Guaranteed Annuities Work

A multi-year guaranteed annuity, or MYGA, is a fixed annuity that locks in a single guaranteed interest rate for a set number of years, commonly three, five, seven, or ten. You hand an insurance company a lump sum, the company guarantees both your principal and a stated rate for the full term, and your money grows tax-deferred until you take it out. People often compare a MYGA to a bank certificate of deposit because the shape is similar: a fixed rate for a fixed term. The mechanics underneath, the tax treatment, and the protections are different, and those differences are the whole point of understanding one before you buy.

This guide explains how the rate and term work, what happens at the end of the term, how surrender charges and market value adjustments can reduce what you get if you leave early, how MYGAs are taxed, and who backs the guarantee. Every figure here is an illustrative example based on stated assumptions, not a live quote. Rates change constantly and vary by insurer, term, and your state, so verify any current rate directly before acting on it.

How the Rate and Term Work

The defining feature of a MYGA is the multi-year guarantee. Unlike some fixed annuities that set a rate for one year and then reset it, a MYGA fixes the rate for the entire term you choose. If you buy a five-year MYGA at a stated rate, that rate applies in year one and in year five alike, regardless of what happens to interest rates in the wider economy.

The growth is also tax-deferred, meaning you do not pay income tax on the interest each year while it stays inside the contract. The interest compounds on the full balance because none of it is being skimmed off for an annual tax bill.

Here is an illustrative example. Suppose you place $100,000 in a five-year MYGA with a guaranteed annual rate of 5%, compounding. After five years the balance would grow to roughly $127,600. That figure is purely arithmetic and assumes you make no withdrawals and the rate is exactly 5% for the whole term; it is not a quote, and the rate you are actually offered will differ. The point is the predictability: at purchase you can calculate the exact ending value, which is what draws people who want a known outcome.

What Happens When the Term Ends

The end of the guarantee period is the moment many buyers overlook, and it matters. As the term closes, the insurer typically gives you a short window, often around 30 days, to decide what to do. You generally have a few options:

• Withdraw the full value as cash, which may trigger taxes (covered below).
• Renew into a new term at whatever rate the insurer offers then, which could be higher or lower than your original rate.
• Roll the money into another annuity or a qualifying account via a tax-deferred exchange, preserving the deferral.
• Annuitize, converting the balance into a stream of income payments.

If you do nothing, many contracts automatically renew you into a new guarantee period, and a new surrender schedule can start with it. That is the trap to watch: a hands-off renewal can quietly lock your money up again. Mark the maturity date when you buy, and read the renewal terms in the contract so the decision is yours rather than the default.

Surrender Charges and the Market Value Adjustment

A MYGA is designed to be held for its full term. If you take out more than the contract's penalty-free allowance during the surrender period, two separate mechanisms can reduce what you receive.

The first is the surrender charge, a fee on early withdrawals above the free amount. Most contracts let you take out a limited portion each year, often around 10%, without penalty; anything beyond that during the surrender period is charged. Surrender charges usually start higher in the first year and step down each year until they reach zero at the end of the term. Our deeper explainer on annuity fees and surrender charges walks through how these schedules are structured.

The second is the market value adjustment, or MVA. This is the part people understand least. An MVA links your early-withdrawal value to how interest rates have moved since you bought the contract. The direction can help or hurt:

• If market interest rates have risen since your purchase, an early surrender value is typically adjusted down.
• If market interest rates have fallen since your purchase, the value may be adjusted up.

The logic is that the insurer invested your money to back its guarantee; if you leave early, the MVA shifts some of the interest-rate gain or loss back to you. The MVA usually applies only during the surrender period and only to amounts above the penalty-free allowance. Combined, surrender charges and a negative MVA mean that cashing out a MYGA early can return less than you put in. This is why a MYGA suits money you genuinely will not need for the length of the term.

How a MYGA Is Taxed

Tax treatment depends on whether the MYGA is held inside a retirement account or with ordinary, after-tax money.

With a non-qualified MYGA (bought with after-tax savings), the interest grows tax-deferred and is taxed as ordinary income when you withdraw it. Withdrawals are generally treated as interest first, so early withdrawals tend to be fully taxable until you have drawn out all the gain. If you take money out before age 59½, the IRS may also apply an additional 10% early-distribution tax on the taxable portion, on top of ordinary income tax.

With a qualified MYGA held inside an IRA or similar account, the annuity follows that account's rules rather than creating separate ones, including any required minimum distributions that apply to the account.

This differs from a bank CD, where interest is generally taxed each year as it is credited even if you leave it in the account. The deferral can be useful, but it is not a tax exemption; the tax arrives when the money comes out. For how annuity income fits a broader plan, see our overview of tax-advantaged retirement accounts. Tax rules change and individual situations vary, so confirm the current treatment with a qualified tax professional before relying on it.

Who Backs the Guarantee

A MYGA's guarantee is only as strong as the company standing behind it. These contracts are not deposits and are not insured by the FDIC. The primary backing is the financial strength of the issuing insurance company, which is why independent insurer financial-strength ratings are worth checking before you buy.

There is a second layer. Every state has a guaranty association that provides a backstop if a member insurer becomes insolvent, up to limits set by state law. These limits vary by state and by product, and the association is not a marketing feature insurers are allowed to lead with. Treat it as a safety net with a cap, not as a reason to ignore the insurer's own strength. Annuity guarantees rest first on the insurer and only then on the guaranty association, so the company you choose matters.

How a MYGA Compares to Other Fixed Options

A MYGA sits between a bank CD and more complex annuities. Against a CD, it offers tax deferral and is backed by an insurer and state guaranty system rather than the FDIC. Against a fixed index annuity, a MYGA is far simpler: it pays a flat stated rate rather than a return tied to an index formula with caps and participation rates. And unlike an income annuity that starts paying you right away, a MYGA in its base form is an accumulation product. If your goal is income now rather than growth, the distinction between immediate and deferred annuities is the more useful frame.

If you are still working out what an annuity is at the most basic level, start with what is an annuity, then compare current offers with care. Quoted rates move week to week, so a figure you saw last month may already be stale; check live rates before deciding.

This is education, not personal financial advice. A MYGA's suitability depends on your time horizon, tax situation, need for liquidity, and the insurer you are considering. Read the contract, verify any current rate directly with the issuer, and consider speaking with a qualified professional before committing money you cannot access for the length of the term.

MYGA: Frequently Asked Questions

Is a MYGA the same as a CD?

No, though they rhyme. Both pay a fixed rate for a fixed term, but a CD is a bank deposit insured by the FDIC and taxed on its interest each year. A MYGA is an insurance contract that grows tax-deferred and is backed by the issuing insurer plus your state's guaranty association, with limits, rather than the FDIC. The MYGA also carries surrender charges and possibly a market value adjustment if you leave early.

Can I lose money in a MYGA?

If you hold it to the end of the term and the insurer remains solvent, your principal and the guaranteed rate are contractually protected. You can effectively lose money by cashing out early during the surrender period, where surrender charges and a negative market value adjustment can reduce your value below what you paid in. The other real risk is the insurer's financial strength, which is why ratings matter.

What happens to my MYGA when the term ends?

You typically get a short window to choose: withdraw the money, renew into a new guarantee period, exchange it into another annuity, or convert it to income. If you do nothing, many contracts auto-renew into a fresh term with a new surrender schedule, so note your maturity date and decide deliberately rather than letting the default decide for you.

How is MYGA interest taxed?

In a non-qualified MYGA, interest grows tax-deferred and is taxed as ordinary income when withdrawn, with withdrawals generally counted as taxable interest first and a possible 10% additional tax before age 59½. Inside an IRA or similar account, the MYGA follows that account's tax rules. Confirm current rules with a tax professional, since they change and depend on your circumstances.
