Retirement tax planning begins long before you retire. Many people don’t realize that the 10 years before Required Minimum Distributions (RMDs) begin may offer one of the best opportunities to reduce lifetime taxes, lower Medicare IRMAA premiums, and create a more tax-efficient retirement income strategy.
What Is an RMD?
A Required Minimum Distribution (RMD) is the minimum amount the IRS requires you to withdraw each year from certain tax-deferred retirement accounts. These accounts generally include: Traditional IRA, SEP IRA, SIMPLE IRA, 401(k), 403(b). Most other employer-sponsored pre-tax retirement plans. When you contributed to these accounts, you received a tax deduction or deferred paying taxes. The IRS eventually wants to collect those taxes, which is why withdrawals become mandatory once you reach a certain age.
When Do RMDs Begin?
Under current law, if you were born in 1960 or later, your RMD generally begins at age 75. You may delay your first RMD until April 1 of the following year. However, doing so means you’ll have to take two RMDs in the same calendar year, which could push you into a higher tax bracket.
How Is Your RMD Calculated?
Your annual RMD is calculated by dividing your retirement account balance as of December 31 of the previous year by an IRS life expectancy factor. For example: Suppose you’re 75 years old and your Traditional IRA balance is $1,000,000. Using the current IRS Uniform Lifetime Table factor of 24.6, your RMD would be approximately: $1,000,000 ÷ 24.6 = about $40,650. Your financial institution usually calculates your RMD for you, but it’s always wise to verify the calculation yourself.
Why Retirement Tax Planning Matters
Here’s the key point many retirees overlook: An RMD is not optional. You must withdraw it whether you need the money or not. Many retirees would prefer to leave their retirement savings invested to continue growing. Unfortunately, once RMDs begin, the IRS requires withdrawals—and those withdrawals are generally taxed as ordinary income. The larger your retirement account grows, the larger your future RMDs may become.
Why Large RMDs Can Become Expensive
RMDs rarely exist in isolation. By the time RMDs begin, many retirees are also receiving: Social Security benefits, Pension income, Investment income, Rental income or other retirement cash flow. When these income sources are combined, several things may happen:
You could move into a higher federal tax bracket – More of your Social Security benefits may become taxable – You may owe higher state income taxes, depending on where you live – Your Medicare premiums could increase.
This is why some financial professionals refer to RMDs as a “retirement tax bomb.”
A Simple Example
Research has shown that retirees who begin strategically withdrawing IRA assets earlier in retirement may maintain lower tax rates over their lifetime. By contrast, waiting until RMDs begin can result in significantly higher taxable income later in retirement. Every situation is different, but it’s not uncommon for retirees who were paying taxes in the 12% bracket before RMDs to find themselves in the 22% or even 24% bracket once RMDs start.
Don’t Forget About Medicare IRMAA
Taxes aren’t the only concern. Higher income can also increase your Medicare costs through a surcharge called IRMAA (Income-Related Monthly Adjustment Amount). If your income exceeds certain thresholds, you’ll pay higher premiums for: Medicare Part B and Medicare Part D. Since RMDs increase your taxable income, they may also increase your Medicare premiums. Depending on your income level, higher taxable income may also trigger the Net Investment Income Tax (NIIT).
One Possible Strategy: Roth Conversions
One strategy many retirees consider is a Roth conversion. A Roth conversion moves money from a Traditional IRA into a Roth IRA. You pay income tax on the amount converted during the year of the conversion, but after that:
- Future qualified withdrawals are tax-free.
- Future investment growth is generally tax-free.
- Roth IRAs are not subject to RMDs during the owner’s lifetime.
By intentionally paying some taxes today, you may reduce future RMDs, lower future taxable income, and potentially reduce Medicare premium surcharges later in retirement.
The “Retirement Tax Window”
One of the best opportunities for Roth conversions often occurs after retirement but before RMDs begin. Consider someone who retires at age 65 and delays claiming Social Security until age 70. During those years, taxable income may be relatively low. This can create an opportunity to perform Roth conversions while remaining in a lower tax bracket. For many retirees, this period—roughly the decade before RMDs begin—is one of the most valuable tax planning windows of retirement.
Roth Conversions Aren’t Right for Everyone
Although Roth conversions can be powerful, they aren’t a one-size-fits-all solution. Converting too much in a single year can: Push you into a higher tax bracket, Increase Medicare IRMAA premiums and Create unnecessary taxes. Other factors also matter, including: your expected retirement spending, Social Security timing, pension income, investment strategy, the five-year Roth conversion rule, estate planning goals. The right strategy depends on your entire retirement plan—not just your tax return for one year.
The Bottom Line
The most important retirement tax decisions are often made before Required Minimum Distributions begin. Planning ahead may help you:
- Reduce future RMDs
- Lower lifetime taxes
- Minimize Medicare IRMAA surcharges
- Create greater flexibility in retirement income
The earlier you begin planning, the more options you’ll have.
Final Thoughts
If retirement is still several years away, now is an excellent time to begin thinking about tax-efficient retirement income planning.
Whether a Roth conversion makes sense depends on your unique financial situation. Your retirement income, Social Security claiming strategy, pensions, investment accounts, and long-term goals all work together. A comprehensive retirement plan can help determine the approach that’s most appropriate for you.
The most successful retirees often begin RMD tax planning years before their first Required Minimum Distribution. Starting early gives you more opportunities to reduce taxes, lower future RMDs, and build a more tax-efficient retirement income strategy.
