RMD basics
Required Minimum Distributions (RMDs) are rules that can affect taxes and retirement cash flow later in life. This guide explains what they are, when they start (at a high level), and how to plan around them.
Educational content only. Not individualized financial, tax, or legal advice.
RMDs are one of those rules that feel complicated until you understand the core idea: certain retirement accounts are designed to be taxed eventually, so withdrawals become required later.
Use this guide if:
- you have a 401(k) or Traditional IRA
- you want to avoid tax surprises later in retirement
- you're coordinating withdrawals with Social Security and other income
What is an RMD (plain language)
An RMD is a required withdrawal amount from certain retirement accounts once you reach a certain age. The amount is based on account value and a government life-expectancy factor.
Planning takeaway: RMDs can increase taxable income later, which can affect how the rest of your retirement income is taxed.
Which accounts are typically affected (high level)
Often affected:
- Traditional IRAs
- Most pre-tax employer plans like traditional 401(k)s (depending on plan rules)
Often not affected the same way:
- Roth IRAs (RMD rules differ)
- Roth accounts may have different required distribution rules depending on the account type and situation
Practical point: Account type matters. If you're not sure which bucket your accounts are in, that's worth clarifying early.
When do RMDs start
RMD starting ages have changed over time and depend on birth year and current rules.
Planning approach: Don't memorize. Put the RMD start window on your timeline and confirm the specific start age as you approach it.

RMDs can:
increase taxable income in later years
change how Social Security is taxed (depending on your situation)
interact with Medicare premium brackets (depending on your situation)
force withdrawals even if you don't "need" the cash flow
The goal is to plan withdrawals earlier so required withdrawals later don't create avoidable surprises.
