Understanding How Tax-Free & Tax-Deferred Retirement Accounts Differ

Traditional IRAs and 401(k)s offer tax-deferred growth, meaning that contributions may be tax-deductible contributions are, reducing taxable income in the year they are made. These accounts provide an immediate tax benefit, as the deposited funds grow without being taxed until they are withdrawn in retirement.

Since withdrawals from a tax-deferred account are taxed as ordinary income, many retirees will pay lower income taxes on their distributions than they would have paid on the contributions during their working years. This is because post-retirement taxable income is often lower than a pre-retirement income and subsequent , leading to a lower tax bracket and potential tax savings.

However, once withdrawals begin, the tax deferral ends, and all distributions from the account are subject to income taxes. Additionally, account holders must start taking Required Minimum Distributions (RMDs) at age 73 (as of 2024), ensuring that taxes are eventually collected.

For example, if someone contributes $6,000 to a Traditional IRA and is in the 24% tax bracket, they could reduce their tax liability by $1,440 that year. However, when withdrawing those funds in retirement, they will owe income tax on both the original contribution and any earnings.

Roth IRAs and Roth 401(k)s, on the other hand, are tax-exempt retirement accounts that allow for tax-free growth and withdrawals. Contributions are made with after-tax dollars, meaning they do not provide an immediate tax benefit, but once in the account, gains can be withdrawn completely tax-free, provided certain conditions are met.

To qualify for tax-free withdrawals, an account holder must:

• Have had the account open for at least five years
• Be at least age 59½ when making withdrawals

Unlike tax-deferred accounts, Roth IRAs do not require minimum distributions during the account holder’s lifetime, allowing funds to continue growing tax-free.

For example, if someone contributes $6,000 per year to a Roth IRA and it grows to $500,000 over time, they can withdraw the entire balance tax-free in retirement. There are no income taxes due on either the contributions or the investment gains.

Choosing between tax-deferred and tax-free retirement accounts depends on your current and expected future tax situation:

• If you are in a high tax bracket now and expect to be in a lower tax bracket later, a Traditional IRA or 401(k) may offer greater tax savings, as the tax deduction lowers your taxable income today.
• If you are in a lower tax bracket now but expect your income and tax liability to rise in the future, a Roth IRA may be a better option, allowing you to pay income taxes now and enjoy tax-free withdrawals later.
• A mix of both tax-deferred and tax-free accounts can provide tax diversification, offering flexibility in retirement.

While tax-deferred and tax-free retirement accounts are the primary focus of this discussion, it's important to recognize the third tax bucket: taxable accounts. Unlike tax-advantaged retirement accounts, taxable accounts do not offer upfront tax deductions or tax-free withdrawals. Instead, they are subject to ongoing taxation, which can impact long-term investment growth.

Taxable accounts include brokerage accounts, savings accounts, and other investment vehicles that are not tied to specific retirement benefits. The key distinction is that any interest, dividends, or capital gains realized within these accounts are taxed in the year they are earned. For example:

• Capital Gains Tax – If you sell an investment for a profit, the gain is taxed at either short-term or long-term capital gains rates, depending on how long you held the asset.
• Dividend and Interest Taxation – Dividends from stocks and interest from bonds or savings accounts are typically taxed as ordinary income or at a lower rate if they qualify as "qualified dividends".

While taxable accounts don’t offer the tax advantages of retirement accounts, they provide greater flexibility. Unlike tax-deferred or tax-free accounts, there are no penalties for early withdrawals, and you can access funds at any time. This makes them useful for supplementing retirement income, covering unexpected expenses, or managing tax-efficient withdrawals by strategically selling assets to minimize tax liability.

When considering your retirement strategy, understanding how taxable accounts interact with tax-deferred and tax-free accounts can help you build a well-balanced plan that optimizes both growth and tax efficiency.
