How a Roth IRA Works

A Roth IRA is a powerful retirement savings vehicle with a simple trade-off: you pay taxes on contributions now, but all future growth and withdrawals are completely tax-free.

Key Benefits

  • Tax-free growth: All investment gains compound without tax drag
  • Tax-free withdrawals: Qualified distributions in retirement are 100% tax-free
  • No required minimum distributions: Unlike Traditional IRAs, Roth IRAs have no RMDs — you never have to withdraw
  • Flexible access: Contributions (not earnings) can be withdrawn anytime without penalty
  • Estate planning: Beneficiaries receive distributions tax-free

Roth IRA vs Taxable Account

In a taxable brokerage account, you pay capital gains tax on investment growth each year. This "tax drag" compounds over time, significantly reducing your final balance compared to a Roth IRA where gains grow tax-free.

For a 35-year investment horizon at 7% return with a 22% tax rate, the Roth IRA advantage can be 30-40% more than the taxable account balance.

Tips

  • Start early: Time is the biggest factor in tax-free compounding — even small contributions at age 25 outpace larger ones at 40
  • Max out if possible: The $7,000 annual limit is "use it or lose it" — you can't make up for missed years
  • Backdoor Roth: If your income exceeds limits, contribute to a Traditional IRA then convert to Roth (check with a tax professional)
  • Choose growth investments: Since gains are tax-free, hold high-growth assets in your Roth to maximize the tax benefit

Frequently Asked Questions

What is a Roth IRA?

A Roth IRA is a retirement account funded with after-tax dollars. Contributions grow tax-free, and qualified withdrawals in retirement are completely tax-free — including all investment gains.

What are the 2026 Roth IRA contribution limits?

For 2026, the limit is $7,000 per year if under 50, and $8,000 if 50 or older (includes $1,000 catch-up). These limits may be reduced or eliminated at higher income levels.

What are the Roth IRA income limits?

For 2026, single filers with MAGI above $150,000 face reduced contribution limits, phasing out completely at $165,000. Married filing jointly phases out between $236,000 and $246,000.

When can I withdraw from a Roth IRA?

Contributions can be withdrawn anytime tax-free and penalty-free. Earnings can be withdrawn tax-free after age 59½ if the account has been open at least 5 years. Early earnings withdrawals incur 10% penalty plus taxes.

Roth IRA vs Traditional IRA?

Roth: pay taxes now, withdraw tax-free later. Traditional: deduct now, pay taxes on withdrawals. Roth is better if you expect higher taxes in retirement. Traditional is better if you expect lower taxes later.

What is a taxable account comparison?

The taxable account column shows what the same contributions would grow to in a regular brokerage account where investment gains are taxed annually at your marginal rate. This highlights the Roth tax-free growth advantage.
