Required Minimum Distributions RMD Rules: What I Wish Someone Had Told Me Sooner

Here’s a stat that honestly shocked me — the IRS penalizes you 25% of the amount you fail to withdraw if you miss your required minimum distribution. Twenty-five percent! I learned about RMD rules the hard way when my dad nearly got hit with that penalty a few years back, and let me tell you, it was a wake-up call for our whole family.

If you’ve got a traditional IRA, 401(k), or another tax-deferred retirement account, understanding required minimum distributions is absolutely critical. So let me walk you through everything I’ve picked up — mistakes included — so you don’t have to stress like we did.

So What Exactly Are Required Minimum Distributions?

In simple terms, required minimum distributions are the minimum amounts you must withdraw from your retirement accounts each year once you hit a certain age. The IRS basically says, “Hey, you got tax breaks putting that money in — now it’s time to start taking it out and paying taxes on it.” Fair enough, I guess.

RMDs apply to traditional IRAs, SEP IRAs, SIMPLE IRAs, 401(k)s, 403(b)s, and most other employer-sponsored retirement plans. Roth IRAs, however, are generally exempt during the owner’s lifetime — which is one reason so many folks love them. The IRS website has a solid breakdown if you want the official source.

When Do You Have to Start Taking RMDs?

This is where things got confusing for my family. The rules changed thanks to the SECURE Act and then the SECURE 2.0 Act. If you turned 73 in 2023 or later, your RMD age is now 73. And starting in 2033, that age bumps up to 75.

My dad was born in 1950, so he had to start at 72. We almost missed his first distribution because we assumed he had until April 1st of the following year — which is technically true for your first RMD only. But here’s the catch: if you delay that first one, you end up taking two distributions in one year, which can push you into a higher tax bracket. That was a rough lesson.

How Are RMDs Actually Calculated?

Okay, the math isn’t terrible. You take your account balance as of December 31st of the previous year and divide it by a life expectancy factor from the IRS Uniform Lifetime Table. For most people, that’s the table you’ll use unless your sole beneficiary is a spouse who’s more than 10 years younger.

For example, if you’re 75 and your account balance was $500,000 at year-end, you’d divide by the factor of 24.6. That gives you an RMD of roughly $20,325. Not super complicated, but you gotta make sure you’re using the updated tables — the IRS revised them in 2022 and the old ones will give you the wrong number.

A Quick Tip From My Own Experience

Most brokerage firms like Fidelity or Schwab will actually calculate your RMD for you and even send reminders. I set my dad up with automatic distributions, and honestly it was the best move we made. One less thing to worry about.

What Happens If You Miss an RMD?

This used to be brutal — a 50% excise tax on the amount not withdrawn. Thankfully, SECURE 2.0 reduced that penalty to 25%. And if you correct the mistake in a timely manner, it drops further to just 10%. Still not ideal, but way better than losing half your distribution to penalties.

You’ll need to file IRS Form 5329 and request a waiver if you have reasonable cause. The IRS is actually pretty understanding if you can show the mistake was genuine and you’ve since taken the distribution.

Don’t Let RMD Rules Catch You Off Guard

Look, retirement planning is already stressful enough without surprise tax penalties. The biggest thing I’ve learned is to plan ahead — know your RMD age, automate your withdrawals, and talk to a tax professional if your situation is even slightly complicated.
