Roth Asset Basics

Roth Asset Basics

“Should I contribute to a Roth IRA? How can I contribute to a Roth IRA?” Before answering those questions, we need to define what Roth assets are. The difference between a Roth IRA and traditional IRA is that Roth contributions are made with after-tax assets, and any growth on assets inside the Roth is tax-free. Withdrawals from Roth accounts are also tax-free once you reach age 59½ and meet a 5-year aging rule. That makes Roth accounts, both IRAs and 401(k)s, very attractive for those in a low tax bracket or with a long-time horizon. Roth accounts also are not subject to required minimum distributions, giving owners more flexibility in growing these balances and building generational wealth. 

There are several ways to contribute to Roth accounts. The right one for you depends on how much you earn, cash flow, time horizon or whether your employer offers a Roth 401(k). If you are within certain modified adjusted growth income limits set forth by the IRS, you can simply open a Roth IRA account and contribute to it directly. For 2025, those income limits are:

  • Single Tax Filer: Contributions phase out between $150,000 and $165,000.
  • Married (filing jointly): Contributions phase out between $236,000 and $246,000.

If you fall below these earnings limits, you can contribute up to a maximum of $7,000 in 2025 ($8,000 if you’re over age 50) or 100% of your earned income, whichever is less. The deadline to contribute to a Roth IRA for tax year 2025 is
April 15, 2026. For young people starting out, contributing to a Roth IRA in the early earnings years can be quite attractive as you’re generally in a lower tax bracket and have many years of investment growth ahead of you. Over time, even small contributions can really add up.

If your employer offers a 401(k), you may have the option of making Roth 401(k) contributions. In 2025, you can contribute up to $23,500 through payroll deductions (with an additional $7,500 for those 50 or older). These are after-tax contributions, and any growth within the Roth account is generally tax-free. 

If your income is higher than the contribution limits for a Roth IRA, don’t worry! Another option is a backdoor Roth IRA, although this is a more complicated way to contribute. To avoid pitfalls and unintended consequences, be sure you are familiar with all the steps and consult a professional tax advisor on how the taxes will work for you.

  1. Make a non-deductible IRA contribution (a maximum of $7,000 or $8,000 if you’re age 50 or older
    in 2025) into a traditional IRA account.
  2. Convert the amount to a Roth IRA account.

Where it gets complicated is calculating how much tax you will owe. Since you are contributing after-tax money to the traditional IRA, one would assume you have satisfied your tax obligation for the Roth conversion. If you have pre-tax assets in any other IRA—401(k) accounts are excluded—the IRS requires you to calculate the pro-rata amount of your contribution, that is pre-tax versus after-tax. While this may sound like a double tax on the Roth contribution, that’s not accurate. The IRS simply wants the saver to pay a pro-rata amount based on pre-tax IRA assets. You’re paying tax now versus when you would take a normal IRA distribution if you had not converted those assets to a Roth. Again, because of the complexity of the tax equation, be sure to check with your CPA or tax advisor for guidance.
