Roth IRA Income Investments

How it works

A Roth IRA takes after-tax dollars in and, if the rules are met, lets both contributions and earnings come out with no federal income tax owed on the way out. There is no deduction in the contribution year. Direct contributions require earned income and phase out above thresholds that are re-indexed annually; on a joint return, a non-earning spouse can still be funded from the working spouse's earned income.

Two separate five-year clocks apply and are easy to conflate. The first starts January 1 of the year of the account holder's first-ever Roth contribution and determines whether earnings are qualified. A second clock runs separately for each conversion and determines whether the additional tax on early withdrawal of that converted amount is avoided. A distribution counts as qualified once the first clock is satisfied and one of these applies: age 59½, death, disability, or a first-home purchase up to a lifetime cap.

Withdrawal ordering favors the account holder: contributions come out first, always free of tax and penalty, then converted amounts oldest-first, then earnings last. A conversion moves pre-tax IRA or plan money into the Roth, with ordinary income tax due in the conversion year; conversions cannot be reversed, since recharacterization of conversions was repealed. The 'backdoor' method — a non-deductible traditional IRA contribution followed by a conversion — runs into the pro-rata rule, so any existing pre-tax traditional, SEP, or SIMPLE IRA balance makes part of that conversion taxable regardless of intent.

There is no required minimum distribution during the original owner's lifetime, and SECURE 2.0 extended that treatment to designated Roth accounts inside employer plans starting in 2024. Custodians report contributions on Form 5498 and distributions on Form 1099-R with a code reflecting whether they consider the distribution qualified; the taxpayer reconciles the actual treatment on Form 8606.

What it pays

The wrapper itself produces nothing. Payout comes entirely from what is held inside it — dividend stocks, bond funds, REITs, CDs, covered-call funds — and the Roth changes only the tax treatment of that stream, not its size. The exemption does the most work against income that would otherwise be taxed annually at ordinary rates: taxable bond interest, REIT dividends, BDC distributions, and the return-of-capital-heavy payouts common to option-income funds.

Because there is no lifetime RMD, distributions can be reinvested indefinitely, so compounding runs uninterrupted by a forced withdrawal schedule. Once the qualified test is met, spendable income equals the gross distribution — no withholding decision, no estimated-tax calculation attached to that money.

Roth distributions never enter adjusted gross income, so they do not push Social Security benefits into taxability and do not raise the modified AGI that sets Medicare IRMAA surcharges two years later. The trade-off runs both directions: a loss inside the Roth produces no deductible loss and cannot be harvested, and the tax already paid on contributions is spent regardless of how the holdings later perform.

Costs and taxes

Qualified distributions are entirely free of federal income tax, and contributions can be withdrawn at any age without tax or penalty since they were already taxed. Earnings withdrawn before the account is qualified are taxed as ordinary income and generally carry an additional 10% tax unless an exception applies. Converted amounts withdrawn inside their own five-year window can trigger that same additional 10% tax even when no income tax is due — the detail that trips up early retirees running conversion ladders.

Contributing above the limit, or contributing at all while over the income phase-out, creates an excess contribution subject to a 6% excise tax for every year it remains uncorrected; the fix is a timely corrective distribution of the excess plus its attributable earnings. Custody cost mirrors any IRA — usually free at large brokers, with annual and transaction fees at specialty custodians holding alternative assets.

Unrelated business taxable income rules apply to a Roth IRA exactly as they do to a traditional one: leverage or an operating partnership held inside the account can generate a tax the Roth itself pays on Form 990-T. Foreign withholding tax deducted at source on non-US dividends cannot be recovered with a foreign tax credit inside any IRA, because there is no US tax liability to credit it against — a permanent leak on any international-income holding placed in a Roth.

Liquidity and time commitment

Contributions are reachable at any age without tax or penalty, making the Roth unusually liquid for a retirement wrapper. Earnings are the part that is locked: withdrawing them before the account is qualified costs both ordinary income tax and the additional tax. Because the first five-year clock starts with the year of the first contribution rather than with the specific dollars contributed, opening the account early — even with a token amount — starts that clock running.

The underlying holdings still control settlement mechanics. A Roth holding a non-traded REIT or an interval fund inherits that fund's redemption queue and gates, regardless of how flexible the wrapper is on paper. Recurring administrative work is small: check eligibility each year against the current income phase-out, file Form 8606 in any year a conversion occurs, and keep beneficiary designations current.

How it goes wrong

The most common error is contributing directly while over the income phase-out and then paying the 6% excise tax for every year the excess sits uncorrected. Close behind is running a backdoor conversion while an existing pre-tax IRA balance is still open, so the pro-rata rule makes most of the conversion taxable when the taxpayer expected none of it to be. Withdrawing earnings before the account is qualified, on the mistaken belief that 'contributions come out first' means everything comes out free, is another frequent misstep.

Converting a large balance in a single year can push income into a higher bracket and add an IRMAA surcharge that shows up two years later. Holding only cash-like assets inside the Roth while higher-growth assets sit in a taxable account wastes the exemption, since it applies to growth and a low-growth holding captures little of it.

Naming a beneficiary subject to the SECURE Act's ten-year rule can cut off decades of intended tax-free compounding at the next generation. State tax treatment is not automatic to assume — most states mirror federal treatment, but conversion-year rules for part-year residents can differ. Treating the account as an emergency fund permanently consumes contribution room that federal law does not allow to be replaced later.
