  1. What Is a Roth Conversion?

Simply put, a Roth Conversion is the process of moving money from a pre-tax retirement account—such as a traditional IRA or 401(k)—into a Roth IRA. You’ll need to pay income taxes on the converted amount in the year of the conversion. However, the key benefit is that once the funds are in a Roth IRA, future withdrawals—including investment gains—are tax-free.
Therefore, choosing the right timing for a Roth Conversion can significantly minimize your tax burden and help you save more in the long run.

  1. When Is the Best Time to Do a Roth Conversion?

1.) During a Market Downturn

The taxes you owe on a Roth Conversion are based on the market value of your investments at the time of conversion. If the market is down, the value of the assets in your traditional IRA may be significantly lower—meaning a smaller tax bill when converting.
Once the market recovers and your assets grow within the Roth IRA, all of that growth will be completely tax-free.

Example:
Let’s say Mr. Chang has $100,000 in his traditional IRA. Due to a market drop, the value falls to $70,000. If he converts now, he only pays taxes on $70,000. Later, if the market rebounds and the account grows to $120,000, no taxes will be owed on that gain when he withdraws the money.

2.) During Periods of Lower Income

Since Roth Conversions count as taxable income, they can potentially bump you into a higher tax bracket. If your income is lower for the year, your tax bracket is also lower, making it a strategic time to convert.

Examples include:

  • A year of unemployment or reduced earnings
  • Taking a sabbatical, starting a new business, or entering a low-income phase
  • The early retirement years before starting Social Security or required minimum distributions (RMDs)

3.) When Tax Rates Are Expected to Rise

If you expect tax rates to increase in the future, converting now at a lower rate can help you lock in savings and avoid higher taxes later.
Although with Trump recently back in office, we may not see immediate tax hikes, there are still reasons to believe future rates could go up:

  • Changes in family status:
    For example, if a couple goes from filing jointly to one person filing as single due to the passing of a spouse, the survivor may face higher tax rates.
  • Moving to a different state:
    If you relocate from a no-income-tax or low-tax state to a high-tax state, a Roth Conversion will trigger much higher state taxes.
  • Choosing where to retire:
    State income taxes should be a key consideration for retirees who plan to rely on pension payments, IRA withdrawals, or investment income.
    Living in a high-tax state could mean higher taxes on these income sources—especially when doing a Roth Conversion.

Conclusion:

When doing a Roth Conversion is a complex decision that should factor in market conditions, income levels, tax brackets, age, RMD timing, and even legacy planning.

Also, did you know that money from a traditional IRA or 401(k) can be used to purchase an annuity? And some annuities offer special advantages when combined with Roth Conversions.
