Can you do a Roth conversion with a fixed index annuity?

No. Your Roth conversion is taxed as ordinary income in the year you convert. It does not matter what your money is in. An annuity, a CD, a stock fund and cash all follow the same rule.

The one difference is how your value is measured. For an annuity in your IRA, the IRS uses the contract's fair market value on the day you convert (Treasury Regulation 1.408A-4, Q&A-14). Your contract may have riders, such as an income rider or a larger death benefit. If so, that value can be higher than the account value on your statement. See Converting an annuity to a Roth for how that works.

The usual reason is timing. You may plan to convert a piece every year for 5 to 10 years. That keeps each year's tax in a lower bracket (see How much to convert each year). In those years, the money you have not yet converted can still fall if the market drops.

A fixed index annuity credits interest based on part of a market index's gain. For each period, that credit is never less than zero. So a bad market year does not shrink your account (before any rider fees or withdrawals). If you are converting slowly over a decade, that floor is the main appeal.

The trade-off is that you give up part of your upside. Caps, participation rates and spreads limit how much of an index gain you get. Index returns usually leave out dividends. And the insurer can change many of these terms over time.

• Floor: in a year the index falls, your index credit is 0%.
• Cap or participation rate: in a strong year, you get only part of the gain.
• Surrender period: if you take out more than the free amount early, you pay a charge, often for 6 to 10 years.
• Your guarantees depend on the insurer's claims-paying ability. Annuities are not FDIC insured.

You have two common ways to set it up. Before you buy, ask the insurer which ones its contracts allow, because the paperwork differs.

You can, but it costs you more than it looks. Money you take from your IRA annuity to pay the tax is its own taxable withdrawal. If you are under 59½, you can also owe a 10% penalty on it.

That withdrawal also counts against your free-withdrawal amount for the year. If you go over it, a surrender charge can apply. Paying the tax from your savings or a taxable account is usually cleaner. It also lets your full amount land in the Roth.

If you are wary of being sold something, you are right to ask. Some of the criticism is fair, and you should hear it before you buy. Fixed index annuities are complex. Regulators at the SEC and FINRA both say your returns are usually lower than the index's gain. They also say getting out early can cost you money through surrender charges.

Agents are usually paid a commission by the insurance company. That does not make a product bad. But it is a reason to ask how the person pitching it to you is paid. Compare it with plain options like CDs, Treasuries or a bond fund.

An FIA makes sense only in a narrow case. It is for money you won't need during the surrender period and want kept safe from loss while you convert over several years. If that does not describe you, a simpler choice may serve you better.

An annuity may be a poor fit for you, even if your conversion plan makes sense.

• You may need the money within the surrender period, for a home repair, care costs or helping family.
• You plan to convert everything in one or two years. You have little waiting time to protect.
• You are fine with stock market swings over many years and want full market growth in your Roth.
• The annuity would hold most of your savings, leaving you a thin emergency fund outside it.
• You are being asked to swap your annuity while it is still in its surrender period. FINRA notes a new contract usually restarts your surrender clock.
