Annuity labels describe different dimensions, so they do not form one clean list of mutually exclusive products. Immediate versus deferred describes when payments begin. Fixed, fixed indexed, registered index-linked, and variable describes how value or payments change. SPIA, DIA, and MYGA are common market labels. QLAC is a federal tax qualification for a qualifying deferred income contract, not a separate market-risk category.
This guide explains product mechanics and vocabulary. Use the annuity buyer's checklist for the separate work of comparing cash value, benefit bases, fees, guarantees, replacement risk, insurer claims-paying ability, and alternatives. Neither guide quotes products or recommends an annuity type.
Why do annuity type lists become confusing?
A single contract can carry several labels at once. For example, a single-premium contract can be immediate or deferred; its payments can be fixed or variable; and eligible deferred income terms can qualify as a QLAC. A fixed indexed or variable deferred annuity can include an optional lifetime-withdrawal rider without becoming an immediate income annuity.
Classify a contract across four questions:
- Funding: one premium or a series of premiums?
- Timing: immediate payout or deferred accumulation and payout?
- Value mechanism: declared fixed interest, index-crediting formula, defined index-linked loss, or investment subaccounts?
- Income mechanism: ordinary withdrawals, annuitization, or an optional lifetime-withdrawal benefit?
Then identify whether it is qualified, nonqualified, or QLAC-eligible for federal tax purposes. Keeping these axes separate prevents a marketing label from hiding the actual contract.
How do the major labels compare?
| Label | What it describes | Primary value or payment mechanism | Central verification |
|---|---|---|---|
| SPIA | Funding and early payout timing | Contractual payments after a single premium | Payment form, covered life, guarantee or refund, inflation terms, and irrevocability |
| DIA | Later payout timing | Contractual payments beginning after a deferral period | Start date, death before income, cancellation rights, and inflation exposure |
| MYGA | Fixed deferred crediting period | Declared rate guaranteed for specified years | Guaranteed period, renewal rate, surrender value, market value adjustment, and issuer |
| FIA | Fixed index-crediting design | Interest credits calculated from an index formula | Cap, participation, spread, term, reset, dividend treatment, and changeable terms |
| RILA | Registered index-linked design | Index-linked return with a buffer or floor and a gain limit | Maximum loss, buffer or floor, cap, term-end calculation, early exit, and prospectus |
| Variable | Registered investment design | Selected subaccounts whose values fluctuate after expenses | Investment options, contract and fund expenses, riders, surrender, and loss exposure |
| QLAC | Federal tax qualification | Deferred lifetime income meeting QLAC requirements | Eligible funding source, aggregate premium limit, latest start date, contract language, and reporting |
The table is a classification aid, not a ranking. Any displayed return, payout, or benefit still depends on the exact contract, issue date, owner and annuitant, state, insurer, options, and withdrawals.
What does SPIA mean?
A single premium immediate annuity is funded with one premium and begins its payout phase within the period defined for an immediate annuity. It may pay for one life, two lives, a fixed period, or another permitted form. Payments can be fixed or variable depending on the contract, so "SPIA" does not itself prove a level monthly amount.
A life-only form can stop at the covered person's death. Period-certain, cash-refund, installment-refund, or survivor forms can preserve specified payments or value for another person, generally with a different initial payment. Ask what happens after each covered death and whether any remaining value exists.
Do not compare a quoted monthly payment without its form. Record the premium, first payment date, payment frequency, covered lives, survivor percentage, guarantee period, refund formula, adjustment feature, and insurer. Annuitization is commonly irrevocable; free-withdrawal language that applied before payout may no longer apply after the election.
What does DIA mean?
A deferred income annuity uses a premium today to establish payments beginning at a future date. Deferral can make the future payment larger than an otherwise similar immediate start, but that does not create a risk-free investment return. The result reflects delayed payments, mortality pooling, interest assumptions, insurer pricing, and the selected death and refund provisions.
The essential comparison includes the purchase date, income start date, whether the date can change, what happens if the annuitant dies before or soon after payments begin, and whether a refund or survivor option applies. A quoted future payment should also be tested in today's purchasing power because a long deferral can magnify inflation risk.
A DIA is not the same as every deferred annuity. MYGAs, FIAs, RILAs, and variable annuities also defer payout, but they maintain an accumulation value under different rules. A DIA is designed around future contractual income rather than one accumulation formula.
What is a MYGA?
A multi-year guaranteed annuity is an industry label for a fixed deferred annuity that guarantees a declared interest rate for a specified multi-year term. After that period, the insurer may offer a renewal rate, another contract option, annuitization, or a withdrawal under the contract's rules.
A MYGA is not a bank certificate of deposit. It is an insurance contract, is not FDIC insured, can use different withdrawal and tax rules, and depends on the issuing insurer. A headline annual rate also does not reveal cash surrender value. Surrender charges and a market value adjustment can reduce the amount received on an early exit.
Compare the guaranteed rate and period, minimum renewal guarantee, compounding method, free-withdrawal allowance, surrender schedule, market value adjustment formula, maturity or renewal process, death benefit, and insurer. Confirm whether the displayed rate applies to the full premium and the full advertised term.
How does a fixed indexed annuity work?
A fixed indexed annuity is a fixed insurance contract. The owner does not directly own the referenced index. Instead, the insurer calculates interest credits under a formula that can use a participation rate, cap, spread, performance-trigger rate, averaging method, or another contract method.
Index changes and credited interest are not the same result. The formula may exclude dividends, measure only selected dates, cap gains, deduct a spread, or reset each term. Some parameters are guaranteed; others may change at renewal subject to contractual minimums or maximums. Ask for both the current terms and the worst terms the contract permits.
A 0% index-crediting floor does not mean every exit preserves the premium. Surrender charges, market value adjustments, rider charges, and withdrawals can reduce cash received. The floor may apply only to a completed index term and only to the index-crediting component. Separate the contract's account value, surrender value, and any rider benefit base.
How is a RILA different from a fixed indexed annuity?
A registered index-linked annuity, sometimes called a buffered annuity or structured annuity, is a security. Its return is linked to an index for a stated term, commonly with a cap or participation limit on gains and a buffer or floor defining part of the loss exposure. Unlike a fixed indexed annuity, a RILA can expose the owner to market loss under the contract formula.
A buffer generally absorbs a stated first portion of index loss, after which the owner bears additional loss. A floor generally sets a maximum loss level for the term. The words are not interchangeable. The outcome can also differ when money leaves before the index term ends because an interim value formula, adjustment, surrender charge, or other provision may apply.
Read the prospectus and contract for the index, term, starting and ending values, dividend treatment, cap or participation rate, buffer or floor, maximum loss, early-exit calculation, fees, renewal process, and available income features. A RILA is not simply an FIA with a higher cap.
How does a variable annuity work?
A variable annuity allocates value among investment options, often called subaccounts. Contract value rises or falls with those selections after contract charges and underlying investment expenses. The owner bears investment risk, although optional death or living-benefit riders can guarantee specified outcomes if their conditions are met.
Costs can appear at several layers: mortality and expense risk charges, administration, underlying fund expenses, rider charges, transfer charges, and surrender charges. Do not use a universal fee percentage. Read the current prospectus and calculate the total dollars deducted under the intended allocation and benefit elections.
A variable annuity inside an IRA or another qualified retirement account does not add federal tax deferral to the account. Any insurance or income feature must be evaluated separately against its fees, restrictions, liquidity, beneficiaries, and alternatives. The same tax boundary applies to other annuity designs held inside a qualified account.
What makes a contract a QLAC in 2026?
A qualified longevity annuity contract is not a separate market-return design. It is a deferred annuity that satisfies federal QLAC requirements and is purchased using an eligible retirement plan or IRA source. The contract must state that it is intended to qualify, and the issuer has reporting obligations.
IRS Notice 2025-67 states that the dollar limitation on premiums paid for QLACs is $210,000 for 2026. That is an individual federal premium limit, not a recommendation, not an annual contribution allowance, and not an amount every plan must accept. Employer plans decide whether to offer a QLAC option, and contract and transfer rules still control.
Under current federal rules, QLAC value is excluded from the account balance used for required minimum distribution calculations before payments begin, and payments generally must begin no later than the first day of the month after the employee reaches age 85. A QLAC cannot be purchased under a Roth IRA. Eligible plan types, spouse and survivor provisions, return-of-premium terms, rescission rights, excess-premium corrections, divorce treatment, and distribution reporting require contract-specific review.
Do not describe a QLAC as avoiding tax. Payments from pre-tax funding are generally included under retirement-plan distribution rules when paid. Its role is deferred lifetime income with a special RMD calculation treatment. The 2026 RMD guide explains the ordinary owner calculation that a QLAC changes.
Can one contract combine several labels?
Yes. A deferred variable annuity may later be annuitized. A fixed indexed annuity may include a lifetime-withdrawal rider. A single-premium contract may be deferred rather than immediate. A qualifying deferred income annuity can also be a QLAC. Product names such as "hybrid," "buffered," "bonus," or "income" do not replace the four-axis classification.
For each proposed contract, complete one sentence: "This is a [funding pattern], [timing], [value mechanism] contract, and income is produced through [withdrawals, rider, or annuitization]." Then add the tax status. If the seller or disclosure cannot reconcile that sentence with the contract, pause the comparison.
Which documents should be compared?
- Contract and all endorsements or riders.
- Application, disclosure, buyer's guide, and state replacement form.
- Prospectus and current investment-option materials for registered products.
- Current and guaranteed rate or index-crediting sheets.
- Illustrations showing guaranteed and non-guaranteed values separately.
- Surrender schedule, market value adjustment, and early-exit formula.
- Income, survivor, refund, death-benefit, and withdrawal elections.
- Issuer identity, producer licenses, compensation disclosure, and complaint or disciplinary checks.
- Tax reporting and QLAC documentation where applicable.
Compare each type against the same household objective, liquidity reserve, time horizon, inflation paths, death timing, survivor needs, and non-annuity alternatives. There is no universally best annuity type and no universal percentage of savings that belongs in one.
The RetireStride retirement projection can represent a fixed income stream in a saved scenario, but it does not calculate an annuity quote, account value, surrender value, index credit, rider benefit, QLAC premium eligibility, insurer risk, or product recommendation. The methodology documents those limits. For another contractual-income comparison, use the pension election guide.
