what is rmds in retirement is one of the most consequential questions any retirement saver will face, because the answer determines how much tax you owe each year after age 73.
The IRS requires most people with tax-deferred retirement accounts to start withdrawing a minimum amount annually, and missing that deadline triggers a penalty that can reach 25% of the amount you should have taken. The problem is that the rules differ by account type, changed significantly under recent legislation, and carry confusing exceptions.
This guide explains the required minimum distribution rules in plain terms, covers the accounts affected, walks through how the amounts are calculated, and shows you exactly how to avoid the penalty.
The Core Definition: What an RMD Actually Is
An RMD is the minimum amount you must withdraw from certain tax-deferred retirement accounts each year once you reach the required beginning age. The IRS explains that these distributions exist because traditional retirement accounts let you defer taxes on contributions, and the government eventually wants to collect. You cannot leave the money growing tax-free indefinitely.
The required beginning age is now 73 for most savers, raised from 72 by the SECURE 2.0 Act. Those born in 1960 or later will see the age rise to 75. Roth IRAs have no lifetime distribution requirement for the original owner, which makes them a powerful estate tool.
The deadline matters as much as the amount. You must take your first distribution by April 1 of the year after you reach your beginning age, then every year by December 31. Miss it and the IRS applies an excise tax on the shortfall.
- Traditional IRA and 401(k): Subject to distributions
- Roth IRA: No lifetime requirement for the owner
- Roth 401(k): No lifetime requirement since 2024
- Inherited accounts: Different rules apply to beneficiaries
Understanding what is rmds in retirement starts with recognizing that this is a tax-compliance obligation, not optional advice.
How to apply this: Check your birth year against the current age thresholds and note your first required deadline on a calendar today.
Which Accounts Fall Under These Rules
Not every retirement account triggers a required distribution, and mixing them up is a common and costly error. Employer plans like 401(k), 403(b), and most 457(b) plans generally require withdrawals. Traditional IRAs and SEP IRAs do too. Roth accounts held by the original owner are exempt during their lifetime.
Inherited accounts follow a separate track. Spouses who inherit can often treat the account as their own. Non-spouse beneficiaries typically must empty inherited accounts within 10 years under the SECURE Act, though annual distributions may be required in some cases depending on the relationship and the year of death.
One practical wrinkle: if you have multiple traditional IRAs, you can calculate each one separately and take the total from any combination. Employer plans do not allow this aggregation — each plan must distribute its own amount.
A common scenario involves someone holding both a 401(k) and a traditional IRA who assumes one withdrawal covers both. It does not, and the plan-level shortfall triggers the penalty independently.
How to apply this: List every tax-deferred account you own, label each as subject to or exempt from distributions, and note whether aggregation is allowed.
Understanding what is rmds in retirement helps you avoid costly mistakes with employer plans like 401(k) and 403(b) accounts. Most 457(b) plans also trigger withdrawals, so knowing what is rmds in retirement prevents confusion across account types.
To calculate your annual amount, you first need to know what is rmds in retirement and then divide your balance by an IRS life expectancy factor. A 73-year-old uses the Uniform Lifetime Table, making what is rmds in retirement a simple division problem.
How the Amount Gets Calculated
The calculation itself is straightforward once you have the right inputs. You divide your account balance by a life expectancy factor from the IRS Uniform Lifetime Table. A 73-year-old uses a factor of about 26.5, so a $500,000 balance produces a required withdrawal near $18,868.
The balance used is the prior December 31 value, not the current one. That timing detail matters in volatile markets — a sharp drop in January does not reduce your obligation for that year.
Three inputs drive the result:
- Your age on December 31 of the distribution year
- The account balance from the previous year-end
- The correct life expectancy factor from the IRS tables
Spouses more than 10 years younger can use a different table that produces smaller withdrawals. Custodians typically calculate the figure for you, but the responsibility for taking it remains yours.
Fidelity and Vanguard both publish calculators and automated distribution services, and the IRS Uniform Lifetime Table is the authoritative source for the factors.
How to apply this: Pull your December 31 statement, find your age factor in IRS Publication 590-B, and divide the two numbers to preview your obligation.
If you miss a withdrawal, knowing what is rmds in retirement could save you from a 25% excise tax on the shortfall. Correcting the error promptly reduces the penalty to 10%, so understanding what is rmds in retirement helps you seek an IRS waiver.
Your obligation is based on the prior December 31 balance, so learning what is rmds in retirement clarifies that a market drop won't lower it. Even if your account shrank sharply, what is rmds in retirement means you still owe the full calculated amount.
Comparing Account Types and Their Distribution Rules
The table below summarizes how the main account types differ, so you can see at a glance where the obligations fall.
| Account type | Lifetime RMD required? | Key detail | Action to take |
|---|---|---|---|
| Traditional IRA | Yes | Aggregation across IRAs allowed | Total all balances, withdraw from any |
| Traditional 401(k) | Yes | Each plan separate | Check each plan's distribution options |
| Roth IRA | No | Owner exempt | Leave it growing |
| Roth 401(k) | No (since 2024) | Previously required | Confirm your plan updated |
| Inherited IRA (non-spouse) | Usually | 10-year rule | Verify annual requirements |
The distinction between aggregation and separate plans is where many people slip. Knowing what is rmds in retirement means knowing that a single withdrawal from one IRA can satisfy all your traditional IRAs, but never a 401(k).
How to apply this: Print this table and mark which rows apply to you, then confirm the rules with each custodian.
Penalties, Waivers, and Fixing a Missed Distribution
Missing a required distribution is expensive but sometimes fixable. The excise tax is 25% of the shortfall, reduced to 10% if you correct the mistake promptly. The IRS can waive the penalty entirely if you show reasonable error and take steps to remedy it.
The correction process involves taking the missed amount, filing Form 5329, and attaching a letter explaining the reason. Common grounds include custodian errors, illness, or incorrect advice. Approval is not guaranteed.
Several strategies reduce the annual burden:
- Qualified Charitable Distributions let you send up to $105,000 (2024 limit) directly to charity, satisfying the requirement without adding to taxable income
- Roth conversions shrink future balances and therefore future obligations
- Aggregation lets you draw from the account with the lowest tax cost
Schwab's retirement specialists often note that QCDs are the most underused tool among charitably inclined retirees. The IRS page on retirement plan distributions confirms the waiver process and QCD rules.
How to apply this: If you missed a distribution, take the amount immediately, then file Form 5329 with a reasonable-cause letter rather than waiting.
Many people searching for what is rmds in retirement are surprised to learn the IRS penalty can reach 25% of the shortfall.
If you correct the missed amount quickly, that 25% drops to 10%, making early action essential when learning what is rmds in retirement.
Frequently Asked Questions About what is rmds in retirement
What happens if I turn 73 but am still working?
If you are still employed and do not own more than 5% of the company, your current employer's 401(k) may be exempt from distributions until you retire. This exception does not apply to traditional IRAs or to plans from former employers.
Verify your ownership status and confirm the plan's rules, because the exemption for what is rmds in retirement depends on active employment and non-ownership.
Can I take more than the minimum?
Yes, and there is no upper limit. Taking extra increases your taxable income for that year, which may push you into a higher bracket or affect Medicare premiums. Some retirees deliberately withdraw more early to reduce future balances and smooth their tax exposure. Any amount above the minimum for what is rmds in retirement is entirely your choice.
Do Roth conversions count toward the requirement?
No. A Roth conversion is a transfer, not a distribution, so it does not satisfy your obligation for the year. You must still take the required amount separately, and the conversion amount is taxed as ordinary income. Retirees sometimes confuse the two and end up short, which is a common trap when learning what is rmds in retirement.
How are inherited accounts handled differently?
Non-spouse beneficiaries generally must empty the account within 10 years, and annual distributions may be required depending on when the original owner died. Spouses have more flexibility and can often roll the account into their own. The rules for what is rmds in retirement on inherited accounts are stricter than for your own.
What if my account balance dropped sharply?
The obligation is based on the prior December 31 balance, so a market decline after that date does not reduce it. You still owe the full amount even if your account shrank. If the drop makes the withdrawal difficult, you can take the distribution in kind rather than selling at a low price.
A common question alongside what is rmds in retirement is whether a market crash after December 31 lowers your required amount.
The answer is no, because what is rmds in retirement calculations always rely on the prior December 31 balance, not current value.
Your Next Steps
Getting this right protects your savings from unnecessary penalties and keeps your tax bill predictable. The essentials:
- Distributions begin at 73 for most savers, rising to 75 for those born in 1960 or later
- Traditional accounts require withdrawals; Roth accounts owned by you do not
- The penalty is 25%, cut to 10% if corrected quickly
- Qualified Charitable Distributions can satisfy the obligation tax-free
Understanding what is rmds in retirement is ultimately about planning, not reacting. Take one action this week: log into each retirement account, confirm your December 31 balance, and set a calendar reminder for your distribution deadline. Then talk to a tax professional about whether a QCD or Roth conversion fits your situation.
