Understanding Required Minimum Distributions Before 73: A Practical Planning Guide

If you are approaching retirement, understanding required minimum distributions before 73 can help you avoid tax surprises later. While many savers do not have to start RMDs until age 73 under current rules, the years leading up to that age are often the most useful time to plan withdrawals, review account types, and estimate how future distributions could affect your income.

This guide explains what RMDs are, why the pre-73 years matter, how to estimate your future required withdrawals, and what steps may help you prepare. The goal is not to make you withdraw early without a reason. It is to help you use the years before RMDs begin more intentionally.

What Required Minimum Distributions Before 73 Really Means

Required minimum distributions, or RMDs, are the minimum amounts the IRS requires you to withdraw each year from certain tax-deferred retirement accounts once you reach the applicable starting age. These accounts commonly include traditional IRAs, SEP IRAs, SIMPLE IRAs, and many workplace retirement plans such as 401(k)s.

When people search for required minimum distributions before 73, they usually are not asking whether they must take mandatory withdrawals early. In most cases, they are really asking: what should I do before RMDs start? That is the key planning question.

Under current law, many retirees begin RMDs at age 73, but rules can change over time. For official details, review the IRS RMD guidance.

So the pre-73 period is best viewed as a planning window. It is the time to estimate future account balances, think through taxes, and decide whether voluntary withdrawals or other moves may make sense before mandatory distributions begin.

Why the Years Before 73 Matter So Much

Many investors focus heavily on building retirement savings and much less on how those savings will be withdrawn. That is understandable, but it can create problems later. The larger your tax-deferred balance becomes by age 73, the larger your future RMD may be.

That matters because RMDs are generally taxable as ordinary income. A larger required withdrawal can increase your taxable income, affect how much of your Social Security benefits are taxed, and potentially influence Medicare-related costs. It does not mean tax-deferred saving was a bad choice. It means the withdrawal phase deserves planning too.

For example, imagine someone retires at 65 with $900,000 in a traditional IRA and leaves the account untouched until age 73. If the account grows during those years, the first RMD could be much higher than expected. That may still be manageable, but it could change the retiree’s tax picture and cash-flow strategy.

The good news is that the years between retirement and age 73 may create flexibility. If your earned income drops after leaving work, you may have a lower-income period before RMDs begin. That can be a valuable time to review withdrawal options and long-term tax exposure.

If you are still building your broader retirement income plan, a Retirement Calculator can help you estimate how savings, timing, and withdrawals may fit together. You can also read how a retirement calculator helps you decide how much to save for a bigger-picture view.

How RMDs Work

Before getting into strategy, it helps to understand the mechanics. RMD planning becomes much easier when you know which accounts are affected and how the annual amount is estimated.

Which accounts are usually subject to RMDs?

In general, the main accounts that may create future RMDs are traditional IRAs, rollover IRAs, SEP IRAs, SIMPLE IRAs, and many employer-sponsored plans such as 401(k)s. Roth IRAs owned by the original account holder are generally not subject to lifetime RMDs, which is one reason Roth assets can add flexibility in retirement.

How is an RMD calculated?

Your annual RMD is typically based on your retirement account balance at the end of the previous year divided by a life expectancy factor from IRS tables. The exact factor depends on your age and circumstances, but the basic calculation is straightforward.

For example, if your traditional IRA balance on December 31 was $500,000 and your distribution factor at age 73 was 26.5, your estimated RMD would be:

• $500,000 / 26.5 = about $18,868

That amount is generally added to your taxable income for the year unless special basis rules apply. In simple terms, larger tax-deferred balances often mean larger required withdrawals.

Why does the pre-73 period affect future RMDs?

Because your first RMD is based largely on how much remains in your tax-deferred accounts by the time RMDs start. Even a few additional years of growth can materially increase the amount you must withdraw.

Consider this comparison:

• Scenario A: IRA balance at 73 is $400,000. Estimated RMD using a 26.5 factor is about $15,094.
• Scenario B: IRA balance at 73 is $900,000. Estimated RMD using the same factor is about $33,962.

That difference can affect taxes, account sequencing, and how much control you have over where your retirement income comes from. If you want to factor in future purchasing power, see how to use an inflation calculator when planning for the future.

It is also important to separate voluntary withdrawals from required withdrawals. Before age 73, you may choose to withdraw from retirement accounts if it supports your tax or spending plan, but that does not automatically mean you are required to do so.

Step-by-Step Guide to Planning Before RMDs Begin

Step 1: List the retirement accounts that could create future RMDs

Start with a full inventory of your retirement accounts. Include traditional IRAs, rollover IRAs, old 401(k)s, current workplace plans, SEP IRAs, SIMPLE IRAs, Roth IRAs, and any other retirement accounts you own.

Then separate them by tax treatment. This matters because not all accounts follow the same withdrawal rules. If most of your retirement savings sit in tax-deferred accounts, future RMDs deserve close attention.

A simple worksheet can include:

1. Account type
2. Current balance
3. Tax treatment
4. IRA or employer plan
5. Expected role in retirement income

Once your accounts are organized in one place, it becomes easier to see which balances may eventually drive larger mandatory withdrawals.

Step 2: Estimate what those accounts might be worth at age 73

Next, project the future value of your tax-deferred accounts. This does not need to be exact. The purpose is to build a realistic planning range, not predict the market perfectly.

For example, suppose you are 67 with $650,000 in a traditional IRA. If the account grows at 6% annually for six years and you make no withdrawals, the balance could grow to roughly $922,000. That future balance would likely produce a much larger first RMD than your current balance suggests.

If you want a quick way to test different return assumptions, the Compound Interest Calculator can help you model how an account may grow between now and age 73.

It is wise to run several scenarios rather than relying on one neat estimate. A 4%, 6%, and 7% annual return can lead to very different outcomes, and a range gives you a stronger planning foundation.

Step 3: Estimate your first-year RMD

Once you have a projected balance, divide it by the appropriate IRS life expectancy factor to estimate your first required withdrawal.

Example:

• Projected IRA balance at 73: $922,000
• Estimated factor: 26.5
• Estimated first RMD: about $34,792

Now connect that number to real life. If you had to add roughly $34,792 to your taxable income in one year, what would that do to your tax bracket, your spending plan, or your other withdrawal decisions? That is where the estimate becomes useful.

Step 4: Compare your estimated RMD with all other retirement income

RMDs should never be viewed in isolation. They are only one part of your retirement income picture. To understand their true impact, compare them with Social Security, pensions, part-time work, taxable investment withdrawals, and cash reserves.

Your income at age 73 might look like this:

• Social Security: $28,000 per year
• Pension: $18,000 per year
• Estimated RMD: $34,792 per year
• Total before other income: $80,792 per year

That total may be higher than expected, especially if you have been focused mainly on spending needs instead of taxable income. Seeing the full picture can help you decide whether changes before age 73 may be worth considering.

For a broader framework, read how much you need to retire.

Step 5: Review actions you might take before age 73

Once you have a rough estimate of future RMDs, you can start evaluating your options. The best strategy depends on your tax bracket, cash needs, estate goals, and account mix, but common planning moves include:

• Taking voluntary withdrawals in lower-income years
• Considering partial Roth conversions
• Coordinating withdrawals with Social Security timing
• Using taxable assets first in some cases
• Planning charitable giving with future withdrawal rules in mind

For example, someone who retires at 66 and delays Social Security until 70 may have several years with relatively modest taxable income. In some cases, that window can be useful for gradually moving money out of traditional accounts rather than waiting for larger mandatory withdrawals later.

For a plain-English overview of the concept, the Investopedia definition of required minimum distributions is also helpful.

Step 6: Build an annual review habit

RMD planning is not a one-time task. Account balances change, market returns vary, retirement dates shift, and tax rules can evolve. A yearly review helps you stay proactive.

At least once a year, update:

1. Your tax-deferred account balances
2. Your expected retirement date
3. Your projected age-73 balances
4. Your estimated first RMD
5. Your total expected retirement income

This habit can make conversations with a tax professional or financial advisor much more productive because your key numbers will already be organized.

Tips for Better Pre-73 RMD Planning

Good RMD planning is less about perfect forecasting and more about staying prepared. You do not need exact future numbers to make smarter decisions today.

Keep your account types organized. Knowing how much you hold in traditional, Roth, and taxable accounts can make future withdrawal planning more flexible.

Also keep inflation in mind. A retirement income amount that feels comfortable today may not stretch as far in the future, so your withdrawal plan should reflect purchasing power, not just nominal dollars.

If you want to test how inflation may affect future income needs, an Inflation Calculator can help.

Common Mistakes to Avoid

Waiting too long to think about RMDs. Many investors focus on accumulation for decades, then realize late that large tax-deferred balances can create tax pressure. Planning before 73 gives you more options.

Assuming all retirement accounts work the same way. Traditional IRAs, 401(k)s, and Roth IRAs follow different rules. Treating them as interchangeable can lead to a less efficient withdrawal strategy.

Focusing only on growth. Investment performance matters, but after-tax income matters more in retirement. A larger balance is not automatically better if it creates avoidable tax friction later.

Ignoring other income sources. An RMD may seem manageable on its own, but the picture changes once you add Social Security, pension income, and other withdrawals.

Using outdated assumptions. RMD ages and related rules can change. Always verify the current rules before making age-based decisions.

Skipping annual reviews. Even a good plan can drift over time. A yearly check-in helps you adapt before small changes turn into larger surprises.

Frequently Asked Questions

Do I have to take required minimum distributions before age 73?

In many cases, no. Under current rules, many investors do not have to begin RMDs until age 73. But the years before that age can be valuable for tax planning and withdrawal strategy.

Which accounts are most likely to create future RMDs?

Traditional IRAs and many employer-sponsored plans such as 401(k)s are common examples. Roth IRAs owned by the original account holder are generally not subject to lifetime RMDs.

Can I reduce future RMDs before they begin?

Possibly. Some investors reduce future RMDs by taking voluntary withdrawals, considering partial Roth conversions, or changing which accounts they use for retirement spending. The right move depends on your broader tax and income plan.

Are required minimum distributions before 73 mainly a tax issue?

Taxes are a major part of the story, but not the only one. Future RMDs can also affect cash flow, Medicare-related costs, and how flexible your retirement income plan feels.

How can I estimate whether my future RMDs may be too large?

Start by projecting your tax-deferred balances to age 73, then estimate a first-year RMD using an IRS life expectancy factor. If you want to test return assumptions first, see how to use an investment return calculator for a small deposit.

The main takeaway is simple: required minimum distributions before 73 are really about preparation. If you estimate your likely balances, model future withdrawals, and review your options early, you give yourself more control over taxes and retirement income later.
