Understanding Required Minimum Distributions (RMDs) for Retirement Accounts

When it comes to retirement planning, how and when you take money out of your retirement accounts can be just as important as how much you put in. One of the most critical rules governing retirement withdrawals, yet often misunderstood, is the Required Minimum Distribution, or RMD.

RMDs are mandatory withdrawals required by the IRS to make sure taxes are eventually paid on tax-deferred retirement savings. Ignoring the rules can result in steep penalties, unnecessary taxes, and avoidable mistakes. This updated 2026 guide explains how RMDs work, when they apply, how they are calculated, how the SECURE Act and SECURE Act 2.0 changed inherited IRA rules, and how to plan proactively.

Key Points

• RMDs are the minimum amounts you must withdraw annually from most tax-deferred retirement accounts.
• RMDs are taxed as ordinary income.
• Roth IRAs do not have RMDs during the owner’s lifetime.
• SECURE Act rules significantly changed RMD requirements for non-spouse inherited IRAs.
• Missing or miscalculating an RMD can trigger penalties of up to 25%, reduced to 10% if corrected promptly.

What Are Required Minimum Distributions?

Required Minimum Distributions are the minimum annual withdrawals the IRS requires from certain retirement accounts once the account holder reaches a specified age. RMD rules apply to:

• Traditional IRAs (including Self-Directed IRAs)
• SEP IRAs
• SIMPLE IRAs
• 401(k), 403(b), and most 457(b) plans

Because these accounts were funded with pre-tax dollars or grew tax-deferred, the IRS uses RMDs to make sure deferred taxes are eventually collected.

Why Do RMDs Exist?

Tax-deferred retirement accounts let you postpone paying income tax for decades. Without RMDs, someone could theoretically defer taxation indefinitely, even across generations. RMD rules prevent that by requiring systematic withdrawals once you reach a certain age or when beneficiaries inherit the account.

When Do RMDs Begin? (2026 Rules)

The RMD starting age has changed over time:

• Before 2020: Age 70½
• SECURE Act (2020): Age 72
• SECURE Act 2.0 (2023):
  • Age 73 for individuals born 1951–1959
  • Age 75 for individuals born 1960 or later

First RMD Deadline

Your first RMD must be taken by April 1 of the year after you reach your RMD age.

All RMDs after that must be taken by December 31 each year.

Important: If you delay your first RMD until April 1, you will take two RMDs in the same tax year, which could push you into a higher tax bracket.

How Are RMDs Calculated?

RMDs are calculated using two factors:

1. Account balance as of December 31 of the prior year
2. Life expectancy factor from IRS tables

Formula:
RMD = Prior-year account balance ÷ Life expectancy factor

Example (2026)

Assume:

• You are age 75 in 2026
• Your IRA balance on December 31, 2025, is $500,000
• Your IRS life expectancy factor is 24.6

Your RMD for 2026 would be:
$500,000 ÷ 24.6 = $20,325

That amount must be withdrawn and reported as taxable income.

Special RMD Rules by Account Type

401(k) Plans

If you are still working and do not own more than 5% of the company, you may delay RMDs from your current employer’s 401(k) until retirement. This does not apply to IRAs or former employer plans.

Roth IRAs

Roth IRAs are not subject to RMDs during the owner’s lifetime, making them excellent tools for tax-efficient retirement and estate planning.

Roth 401(k)s

Starting in 2024, SECURE Act 2.0 eliminated RMDs for Roth 401(k)s, bringing them in line with Roth IRAs.

RMD Penalties (2026)

The penalty for missing an RMD has been reduced:

• 25% penalty on the amount not withdrawn
• Reduced to 10% if corrected within two years and reasonable cause is shown

Even with these lower penalties, mistakes can be costly, especially when they involve multiple accounts or years.

SECURE Act Rules for Inherited IRAs (Non-Spouse Beneficiaries)

One major change to RMD rules came from the SECURE Act, which significantly altered how non-spouse beneficiaries must withdraw inherited retirement accounts.

The 10-Year Rule

Most non-spouse beneficiaries inheriting an IRA from someone who died after 2019 must fully distribute the account within 10 years of the original owner’s death.

Annual RMDs May Still Apply

If the original IRA owner had already started RMDs before death, IRS guidance requires beneficiaries to:

• Take annual RMDs during years 1–9
• Fully distribute the account by the end of year 10

Skipping these inherited RMDs can trigger penalties, a common trap for beneficiaries.

Exceptions to the 10-Year Rule

Certain Eligible Designated Beneficiaries can still stretch distributions over life expectancy, including:

• Surviving spouses
• Minor children until they reach majority
• Disabled or chronically ill individuals
• Beneficiaries not more than 10 years younger than the decedent

Inherited IRA RMD rules are now among the most complex areas of retirement taxation.

SECURE Act 2.0 and Inherited Roth IRA RMD Rules

While Roth IRAs are not subject to RMDs during the original owner’s lifetime, SECURE Act 2.0 keeps the 10-year distribution rule for most non-spouse beneficiaries who inherit a Roth IRA.

Although distributions from an inherited Roth IRA are usually tax-free, the account must still be emptied by the end of the 10th year after the original owner’s death. Unlike inherited traditional IRAs, annual RMDs are typically not required for inherited Roth IRAs during years 1–9. However, failing to fully withdraw by year 10 can lead to IRS penalties. Beneficiaries must carefully plan Roth withdrawals even when no income tax is owed.

Tax Implications of RMDs

RMDs are taxed as ordinary income, which can:

• Push you into higher tax brackets
• Increase Medicare Part B and D premiums (IRMAA)
• Cause more Social Security benefits to become taxable

Because of these ripple effects, RMD planning should never be done in isolation.

Tax-Efficient RMD Planning Strategies

• Roth Conversions: Convert pre-tax assets to Roth IRAs before RMD age to reduce future taxable RMDs
• Qualified Charitable Distributions (QCDs): Donate up to $100,000 annually directly from an IRA (age 70½+) to satisfy RMDs tax-free
• Strategic Withdrawals: Smooth income across years to manage brackets and Medicare premiums
• Account Consolidation: Simplify calculations and reduce the risk of mistakes

Common RMD Mistakes to Avoid

1. Missing deadlines
2. Using the wrong IRS life expectancy table
3. Forgetting inherited IRA RMDs
4. Assuming custodians always calculate correctly
5. Ignoring tax and Medicare consequences
