The IRS spends a lot of energy making sure people don’t tap their retirement accounts, imposing taxes and penalties on most early withdrawals. So it might surprise you to learn that at a certain point, the agency forces you to take money out of your account through required minimum distributions.
These distributions, often referred to as RMDs, are primarily enforced on tax-deferred retirement accounts: workplace plans such as 401(k)s and 403(b)s, as well as traditional individual retirement accounts and self-employed retirement plans, including SIMPLE and SEP IRAs. Roth 401(k) accounts are also subject to RMDs.
Required minimum distribution (RMD) rules
You’ll note one account missing from the list above: Roth IRAs don't require RMDs while the account holder is alive. But if you’ve inherited a Roth IRA, you might be required to take distributions. You can read more about the rules for Roth IRA RMDs here.
RMDs are a minimum amount you must withdraw from your retirement account each year by Dec. 31, generally beginning in the year you turn 72. (The RMD age was increased from 70½ as part of the Setting Every Community Up for Retirement Enhancement Act, or SECURE Act, which passed at the end of 2019.) There are a couple of exceptions:
The IRS gives you a little leeway in your first year: You get until April 1 of the year following the year in which you turn 72 to take your first RMD. However, using that extra time means you’ll need to take two RMDs in one year — one for the year you turned 72 and one for the current year.
Distributions from 401(k), 403(b) and other profit-sharing or defined-contribution plans can be put off until you actually retire, if you’re still working at age 72.
If you skip a required distribution or fail to take enough, there's a steep, steep penalty: When you file taxes, you'll owe 50% of the amount not distributed.
Other important things to know: You can always withdraw more than the minimum — this is a floor, not a ceiling — and unless the money you withdraw was already taxed, these distributions will be taxable as income in the year you take them. In other words, this is an opportunity for the IRS to start collecting those taxes you’ve been able to defer.
How RMDs are calculated
RMDs are calculated via some easy math — just kidding! This is the IRS we’re talking about.
To calculate your retired minimum distribution for the current year, divide your account balance at the end of the last year by a distribution period that is based on your age. Those periods are available in two tables:

RMDs when you have multiple accounts
If you have more than one retirement account that's subject to RMDs, you’ll have to calculate the distribution for each account separately. However, if you have more than one IRA, the IRS allows you to take your total IRA RMD from just one of them.
The same rule applies if you have more than one 403(b) plan. But if you have multiple 401(k)s or 457(b)s, you must pull an RMD from each account separately.
