A Roth IRA accepts after-tax contributions and can provide tax-free qualified withdrawals under U.S. income, contribution, and distribution rules.
A Roth IRA is a U.S. individual retirement arrangement funded with after-tax money. Contributions are not deductible, investment earnings generally are not taxed while inside the account, and qualified distributions are excluded from federal taxable income.
The Roth IRA is an account, not an investment. Its return and risk depend on the cash, funds, stocks, bonds, or other permitted assets held inside it.
An individual opens a Roth IRA with a bank, brokerage, mutual-fund company, or other qualified custodian. The account can receive eligible annual contributions, transfers from another Roth IRA, conversions from a traditional IRA, or qualifying rollovers from an employer plan.
Regular contributions use money that has already been included in taxable income and do not create a current federal deduction. Interest, dividends, and realized gains generally do not create annual federal tax while they remain inside the Roth IRA. The long-term tax benefit depends on meeting the distribution rules rather than merely holding the account.
A person generally needs taxable compensation, or qualifying spousal compensation on a joint return, to make a regular Roth IRA contribution. The permitted contribution is reduced and eventually eliminated as modified adjusted gross income rises through the applicable range.
The annual limit applies to traditional and Roth IRA contributions in total, not separately. For example, contributing part of the limit to a traditional IRA leaves only the unused portion available for a Roth IRA contribution. Rollovers and conversions generally do not consume that annual contribution limit.
Dollar limits and income phaseouts can change each tax year. Current IRS tables should be checked before contributing, especially when income is near a phaseout boundary.
A qualified distribution generally requires both:
When both tests are met, contributions and earnings in the distribution are generally tax-free. If the distribution is not qualified, federal ordering rules generally treat Roth IRA value as leaving in this sequence:
Regular contributions therefore generally come out before earnings, but that does not mean every Roth IRA withdrawal is tax- and penalty-free. Converted amounts can have separate five-year additional-tax periods, and earnings in a nonqualified distribution can be taxable. Exceptions and special distributions add further complexity.
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Contribution | After-tax and not deductible | May be deductible or nondeductible |
| Direct-contribution income limit | Modified AGI can reduce or eliminate eligibility | No income ceiling to contribute when compensation requirements are met, but deduction limits may apply |
| Earnings while inside account | Generally no current annual federal tax | Tax-deferred |
| Qualified withdrawal | Generally tax-free | Untaxed contributions and earnings are generally taxable |
| Owner required minimum distributions | Generally none during original owner’s lifetime | Generally required under current age and timing rules |
This comparison does not identify a universal winner. Current and future marginal tax rates, deduction eligibility, employer-plan options, cash flow, time horizon, estate objectives, and expected withdrawal needs can change the analysis. See Traditional IRA vs. Roth IRA for a fuller decision framework.
Sam contributes $5,000 of after-tax compensation to a Roth IRA and invests it. Years later, the account is worth $7,000.
If Sam takes a qualified distribution, the entire $7,000 is generally excluded from federal taxable income. If the distribution is not qualified, the result depends on Sam’s Roth IRA history and the ordering rules. The first $5,000 may represent regular contribution basis, while the $2,000 of earnings can have different income-tax and additional-tax treatment.
The example assumes no other Roth IRAs, conversions, rollovers, prior distributions, excess contributions, or special exceptions. Federal rules aggregate a person’s Roth IRAs for distribution-ordering purposes.
A Roth conversion moves value from a traditional IRA or eligible pre-tax plan into a Roth IRA. Conversion eligibility is not determined by the direct-contribution income phaseout, but untaxed value converted is generally included in current income.
A conversion also does not create a second annual contribution allowance. It changes the tax character and location of existing retirement assets. Conversions made after 2017 generally cannot be reversed through recharacterization.
Check current contribution eligibility, expected taxable compensation, filing status, modified AGI, and contributions already made to all IRAs. Review the custodian’s fees, investment menu, cash terms, services, transfer policies, and beneficiary procedures.
For a contribution choice, compare the value of a current traditional IRA deduction, if available, with the potential value of qualified tax-free Roth distributions. For a conversion, separately estimate taxable income, interactions with deductions and credits, available cash for taxes, and the consequences of an irreversible transaction.
