For decades you focus on putting money into retirement accounts. At some point, the IRS requires you to start taking it out. These mandatory withdrawals, called required minimum distributions, apply to most tax-deferred accounts and carry real penalties if you miss them. Understanding the timing and the math keeps you compliant and keeps your tax bill predictable.
1. What an RMD Is and Why It Exists
A required minimum distribution is the smallest amount you must withdraw each year from certain retirement accounts once you reach the required age. The rule exists because accounts like Traditional IRAs and 401(k)s were funded with pre-tax dollars. The government deferred taxing that money and eventually wants its share.
RMDs apply to Traditional IRAs, most 401(k)s, and similar tax-deferred plans. Roth IRAs are notably exempt during the original owner’s lifetime, one of their biggest advantages. If you are weighing account types with this in mind, our comparison of Roth and Traditional IRAs explains the distinction.
2. The Current RMD Age
The starting age has changed in recent years. Under the SECURE 2.0 Act, the age at which RMDs begin was raised to 73 for many savers, up from earlier ages. Future adjustments are scheduled as well, so the exact age that applies to you depends on your birth year.
Because the rules have shifted more than once, this is an area where you should verify the specifics against current IRS guidance rather than relying on older advice. Getting the start year right matters, since your first distribution sets the pattern for every year that follows. This article is educational and not personalized financial advice.
3. How RMDs Are Calculated
The amount is not arbitrary. It is based on your account balance at the end of the prior year divided by a life-expectancy factor published by the IRS. As you age, the factor shrinks, so the required percentage of your balance generally rises over time.
You calculate the RMD separately for each account type, though the rules for combining them differ. For multiple IRAs you may total the required amounts and withdraw from one or several. For 401(k) accounts, each plan generally requires its own distribution. The custodian can often compute the figure for you, but the responsibility to withdraw is yours.
4. The Penalty for Missing One
Missing an RMD historically carried a steep excise tax on the amount you failed to withdraw. SECURE 2.0 reduced that penalty, and it can be reduced further if you correct the shortfall promptly within a defined window. Even so, the cost of forgetting is high enough that it deserves attention.
If you realize you missed a distribution, taking the shortfall as soon as possible and following the IRS correction process is the right move. Because the penalty structure changed recently, confirm the current rate and correction procedure with up-to-date IRS guidance before you act.
5. Strategies to Manage RMDs
Once distributions begin, they add to your taxable income whether you need the cash or not. Several planning moves can soften that impact, and the options below are worth discussing with a professional.
- Consider Roth conversions in lower-income years before RMDs begin.
- Use a qualified charitable distribution to satisfy an RMD tax-efficiently if eligible.
- Coordinate withdrawals with other income to manage your tax bracket.
- Reinvest money you do not need into a taxable account to keep it growing.
- Plan around Medicare premium thresholds that rise with income.
- Set calendar reminders so you never miss the annual deadline.
6. RMDs and Inherited Accounts
The rules get more complicated when an account is inherited. Recent law changed how quickly many non-spouse beneficiaries must empty an inherited account, often requiring the full balance to be distributed within a set number of years rather than stretched over a lifetime.
Spouses who inherit generally have more flexible options. Because inherited-account rules have been revised and clarified repeatedly, they are among the easiest to get wrong. If you inherit a 401(k) and are deciding whether to move it, our guide on rolling over a 401(k) covers the mechanics, though inherited accounts follow special rules. Treat current IRS guidance as the authority and consider professional help before taking or skipping any withdrawal.
7. Staying Ahead of the Deadline
Your first RMD has a special timing quirk: you may be allowed to delay it into the following year, but doing so means taking two distributions in one year and potentially a larger combined tax hit. Every RMD after the first follows a year-end deadline.
The simplest defense is a system. Ask your custodian whether they can automate the annual withdrawal, mark the deadline on your calendar, and review the amount each year as your balance and life-expectancy factor change. A small amount of attention prevents an expensive mistake.
RMDs are not optional. Know your start age under current rules, calculate the amount accurately each year, and never miss the deadline, since the penalty for skipping one can be significant.
Frequently Asked Questions
At what age do RMDs start now?
Under the SECURE 2.0 Act, the starting age was raised to 73 for many savers, with further changes scheduled. The exact age depends on your birth year, so confirm the specifics against current IRS guidance before planning your first withdrawal.
Do Roth accounts have RMDs?
Roth IRAs are not subject to RMDs during the original owner’s lifetime, which makes them valuable for legacy planning. Rules for inherited Roth accounts differ, so check the current IRS guidance for beneficiaries.
What happens if I forget to take an RMD?
Missing an RMD triggers an excise tax on the amount not withdrawn, though SECURE 2.0 lowered it and allows further reduction if corrected quickly. Take the shortfall promptly and follow the IRS correction process, and verify the current penalty rate.
