What Is a Roth IRA?
A Roth IRA (Individual Retirement Account) is a special retirement savings account established under the Internal Revenue Code. Unlike a Traditional IRA, contributions to a Roth IRA are made with after-tax dollars — meaning you pay income tax before depositing money. In return, all qualified withdrawals in retirement are 100% tax-free, including all investment earnings, dividends, and capital gains.
Tax-Free Growth
All earnings — dividends, interest, and capital gains — grow completely tax-free inside your Roth IRA. No annual tax drag on your compounding returns.
Flexible Withdrawals
Withdraw your direct contributions at any time with zero taxes or penalties. Earnings become tax-free after age 59½ and the 5-year rule.
No RMDs
Unlike Traditional IRAs, Roth IRAs have no Required Minimum Distributions. Your money can compound tax-free for your entire lifetime.
Estate Planning
Pass your Roth IRA to heirs who can receive tax-free distributions, making it a powerful tool for multi-generational wealth transfer.

Steps to Open & Fund Your Roth IRA
Follow these steps to start building your tax-free retirement savings today.
Check Your Eligibility
Verify your Modified Adjusted Gross Income (MAGI) falls within IRS limits. For 2025, single filers phase out between $150,000–$165,000; married couples between $236,000–$246,000.
Choose a Brokerage
Open a Roth IRA account with a reputable brokerage like Fidelity, Vanguard, or Charles Schwab. Look for zero-fee accounts with a wide selection of low-cost index funds.
Fund Your Account
Contribute up to $7,000 per year (or $8,000 if age 50+) for 2025. Set up automatic monthly transfers to maximize consistency and dollar-cost averaging.
Select Your Investments
Choose diversified, low-cost index funds or target-date retirement funds. A classic portfolio splits between total stock market and bond index funds based on your risk tolerance.
Monitor & Rebalance
Review your portfolio annually to ensure your asset allocation matches your retirement timeline. Rebalance if any asset class drifts more than 5% from your target.
