Registered Index-Linked Annuities (RILAs): the middle ground
RILAs trade some downside protection for higher upside than fixed-indexed annuities. Where they fit and how they compare.
A registered index-linked annuity (RILA) — also called a "buffer" or "structured" annuity — sits between a fixed-indexed annuity and a variable annuity: more upside than an FIA, but unlike an FIA you can lose money. The entire decision comes down to one feature — the buffer or floor — so this guide covers how a RILA works, the cap-and-buffer math with real numbers, buffer vs. floor, the costs and taxes, who it fits, and the mistakes that trip people up.
How a RILA works
You get index-linked returns with a higher cap than a typical FIA, in exchange for accepting limited downside. Your money is never actually invested in the index; the insurer credits you a return tied to the index's performance over a set crediting term, subject to a cap on the upside and a buffer or floor on the downside.
Protection comes in one of two shapes. A buffer means the insurer absorbs the first X% of loss and you take everything beyond it. A floor means your loss is capped at X% and you take every point of loss down to that limit. A RILA is a registered security — sold by prospectus and regulated by the SEC and FINRA — which is why the salesperson must hold a securities license (FINRA-registered) in addition to an insurance license, and must hand you a prospectus. The licensed specialists we match readers with are insurance agents and may not hold a securities license, so ask before you discuss a RILA with one.
Crediting terms are typically 1, 3, or 6 years, and caps generally run higher than an FIA's — often in the 10–15% range versus roughly 4–8% on a fixed-indexed annuity — precisely because you are taking on some risk to earn them.
The cap-and-buffer math, with real numbers
Caps and buffers are easy to misjudge in the abstract, so put dollars on them. Say you put $100,000 into a RILA tracking the S&P 500 with a 12% cap and a 10% buffer over a one-year term.
- Index up 20%: your gain is capped at 12%, so you credit +$12,000 → balance $112,000. The 8 points above the cap are gone.
- Index up 7%: you are under the cap, so you credit the full 7% → +$7,000 → balance $107,000.
- Index down 6%: the 10% buffer absorbs it entirely → $0 loss → balance stays $100,000.
- Index down 25%: the buffer eats the first 10 points; you take the remaining 15% → −$15,000 → balance $85,000.
That last line is the one people forget. The buffer is real protection, but in a serious downturn you can still lose a meaningful chunk of principal. The cap, meanwhile, quietly costs you the biggest up years — the years that historically drive most of the market's long-run return.
Buffer vs. floor (don't confuse them)
| Index return | Buffer (10%) | Floor (−10%) |
|---|---|---|
| Down 5% | You lose 0% (absorbed) | You lose 5% |
| Down 15% | You lose 5% (15 − 10) | You lose 10% (floor) |
| Down 30% | You lose 20% (30 − 10) | You lose 10% (floor) |
A buffer protects the first losses; a floor caps the maximum loss. In a mild down year a buffer can leave you at zero loss while a floor still nicks you — but in a severe crash a floor is the safer structure, because your loss can never exceed it. Buffers, in trade, usually come with higher caps, which is why most products are sold with buffers.
What it really costs
RILAs rarely show a headline "fee" the way variable annuities do. The cost is embedded in the cap — every year the index runs hot, the points above your cap are the insurer's margin. There are still explicit costs to read for, though:
- Surrender charges: typically a 6-year schedule starting around 7% and stepping down roughly one point a year. Cash out in year two and you could lose 6% off the top.
- Interim value (mid-term withdrawals): take money out before a crediting term ends — even a penalty-free withdrawal — and most RILAs value it with an "interim value" formula instead of the end-of-term buffer or floor. You can lose money mid-term even if the index is up. Some contracts also apply an interest-rate market value adjustment (MVA).
- Optional riders: income or death-benefit riders, if offered, usually carry an annual charge of roughly 0.5%–1.5% of the contract value.
How RILA gains are taxed
Inside the contract, gains grow tax-deferred — you owe nothing until you take money out. That deferral is a genuine perk if you have already maxed your 401(k) and IRA and want another tax-sheltered bucket.
The catch comes at withdrawal. In a non-qualified (after-tax) annuity, gains come out first and are taxed as ordinary income, not at the lower long-term capital gains rate you would get on a brokerage holding. Withdrawals before age 59½ generally add a 10% federal penalty on the gains. The rules are summarized by the IRS, and your specific contract terms are spelled out in the SEC-filed prospectus.
Who it's for — and who should skip it
A RILA is a decision product: it only makes sense if the buffer-for-cap trade matches what you are trying to do.
- Good fit: investors who want more growth than an FIA and will accept some loss for it.
- Good fit: people roughly 5–15 years from retirement who would otherwise hold equities but want to dampen — not eliminate — downside on a slice of money, tax-deferred.
- Poor fit: anyone who needs principal protection. That is an FIA or MYGA, not a RILA.
- Poor fit: investors who want full market upside and can stomach the volatility — a low-cost index fund keeps the big up years a cap would chop off.
- Poor fit: anyone who may need the money inside the surrender period.
Pros and cons at a glance
| Pros | Cons |
|---|---|
| Higher caps than an FIA | You can lose principal — it is not no-loss |
| Defined downside (buffer or floor) | Caps limit your best up years |
| Tax-deferred growth | Gains taxed as ordinary income, not capital gains |
| Usually lower explicit fees than a variable annuity | Surrender charges and MVA lock up the money |
Mistakes to avoid
- Confusing the buffer with a floor. A 10% buffer does nothing to stop a 30% crash from costing you 20%.
- Anchoring on the teaser cap. The high opening cap can reset down at renewal — judge the contract on its guaranteed minimum.
- Ignoring the crediting term. A 6-year term means your money is exposed and locked far longer than a 1-year term; you cannot bail mid-term without consequences.
- Overfunding it. A RILA should be one sleeve of a plan, not the whole plan — keep liquid money outside the surrender cage.
How to evaluate one — your next steps
Treat the purchase like underwriting the insurer, not just the product.
- Get the prospectus and read the buffer/floor, current cap, and guaranteed minimum cap.
- Check the carrier's strength — the protection is only as good as the insurer behind it; look up its financial-strength ratings.
- Confirm the surrender schedule and the free-withdrawal allowance in writing.
- Verify the rep's license through FINRA BrokerCheck before you hand over money.
- Model it against alternatives — an FIA for protection, an index fund for full upside — so you know exactly what the cap is buying you.
Bottom line: a RILA trades an FIA's 0% floor for higher capped upside via a buffer or floor. Know which structure you have, know its limits, and size it as one piece of a broader plan — it is not a no-loss product.
