What Are Required Minimum Distributions?

Definition

RMD = Required Minimum Distribution

What It Means:

• Minimum amount you must withdraw from retirement accounts each year
• Starting at a certain age
• Fully taxable as ordinary income
• Why: IRS wants tax revenue from pre-tax accounts

Key Point: You must take RMDs whether you need the money or not.

The Purpose

Why RMDs Exist:

• Retirement accounts were funded with pre-tax money
• IRS deferred taxes during accumulation
• Now IRS wants tax revenue
• Why: Tax collection on deferred income

Philosophy: "You've had the tax benefit, now it's time to pay taxes."

When RMDs Start

Current Rules (2026)

RMD Age: 73

Who Must Take RMDs:

• Traditional IRA owners
• 401(k), 403(b), 457(b) participants
• SEP-IRA, SIMPLE IRA owners
• Other qualified retirement plans
• Why: All pre-tax retirement accounts

Timeline:

• First RMD: By April 1 of year after turning 73
• Subsequent RMDs: By December 31 each year
• Why: Gives time for first RMD, then annual requirement

Historical Changes

RMD Age History:

• 2019: Age 70.5
• 2020: Age 72 (SECURE Act)
• 2023: Age 73 (SECURE 2.0)
• 2033: Age 75 (SECURE 2.0)
• Why: Gradually increasing age

2026: Age 73 applies

Which Accounts Require RMDs

Accounts That Require RMDs

1. Traditional IRAs:

• All traditional IRAs
• Must take RMDs
• Why: Pre-tax contributions

2. 401(k) Plans:

• Traditional 401(k)
• Must take RMDs
• Why: Pre-tax contributions

3. 403(b) Plans:

• Traditional 403(b)
• Must take RMDs
• Why: Pre-tax contributions

4. 457(b) Plans:

• Government 457(b)
• Must take RMDs
• Why: Pre-tax contributions

5. SEP-IRAs:

• Simplified Employee Pension IRAs
• Must take RMDs
• Why: Pre-tax contributions

6. SIMPLE IRAs:

• Savings Incentive Match Plans
• Must take RMDs
• Why: Pre-tax contributions

Accounts That Don't Require RMDs

1. Roth IRAs:

• No RMDs during owner's lifetime
• Why: After-tax contributions, already taxed

2. Roth 401(k):

• No RMDs during owner's lifetime (if still working)
• RMDs after separation from service (but can roll to Roth IRA)
• Why: After-tax contributions

3. Health Savings Accounts (HSAs):

• No RMDs
• Why: Different type of account

4. Taxable Investment Accounts:

• No RMDs
• Why: Not retirement accounts

How RMDs Are Calculated

The Formula

RMD = Account Balance ÷ Life Expectancy Factor

Account Balance:

• December 31 balance of prior year
• Why: Based on prior year-end value

Life Expectancy Factor:

• From IRS Uniform Lifetime Table
• Based on your age
• Why: Estimates how long you'll live

The Uniform Lifetime Table

How It Works:

• Table provides life expectancy factor for each age
• Older age = smaller factor = larger RMD
• Why: Older people have shorter life expectancy

Example Factors (approximate):

• Age 73: 26.5
• Age 75: 24.6
• Age 80: 20.2
• Age 85: 16.0
• Age 90: 11.4

Calculation Example

Situation: Age 75, $1,000,000 IRA balance (Dec 31 prior year)

Life Expectancy Factor: 24.6 (from table)

RMD: $1,000,000 ÷ 24.6 = $40,650

Must Withdraw: At least $40,650 this year

Multiple Accounts

IRA Accounts:

• Calculate RMD for each IRA
• Can take total from any IRA(s)
• Why: Flexibility in withdrawal

401(k) Accounts:

• Calculate RMD for each 401(k)
• Must take from each account separately
• Why: Different rules than IRAs

Example:

• IRA 1: $500,000, RMD $20,000
• IRA 2: $300,000, RMD $12,000
• Can take $32,000 from either or both IRAs

RMD Tax Implications

Fully Taxable

RMDs Are Taxed:

• As ordinary income
• At your tax bracket (10-37%)
• Why: Pre-tax contributions, now taxable

Example: $40,000 RMD at 22% bracket

• Tax: $8,800
• After-tax: $31,200

Can Push You Into Higher Bracket

Bracket Impact:

• RMDs add to your income
• May push you into higher bracket
• Why: Increases total taxable income

Example:

• Other income: $70,000 (22% bracket)
• RMD: $40,000
• Total: $110,000 (24% bracket)
• RMD taxed at 24%: $9,600

Social Security Taxation

RMDs Increase Social Security Tax:

• RMDs count in combined income
• Makes more Social Security taxable
• Why: Increases AGI

Example:

• Social Security: $30,000
• RMD: $40,000
• Combined income: $40,000 + $15,000 = $55,000
• More Social Security taxable: Due to RMD

Medicare Premiums (IRMAA)

RMDs Increase Medicare Premiums:

• RMDs count in MAGI
• May trigger IRMAA surcharges
• Why: Increases MAGI

Example:

• MAGI: $190,000 (no IRMAA)
• RMD: $30,000
• New MAGI: $220,000
• IRMAA Tier 1: Extra $140/month

Strategies to Minimize RMD Taxes

Strategy 1: Roth Conversions Before RMDs

Convert Early:

• Convert traditional to Roth before age 73
• Pay tax now (at lower bracket)
• No RMDs from Roth
• Why: Eliminates RMDs, tax-free withdrawals

Example:

• Convert $200,000 at age 70 (22% bracket)
• Tax: $44,000
• No RMDs from Roth: Saves on future taxes

Strategy 2: Qualified Charitable Distributions

QCDs Count Toward RMD:

• Donate RMD directly to charity
• Up to $105,000/year (2026)
• Not included in income
• Why: Tax-free way to satisfy RMD

Example:

• RMD: $40,000
• Donate $20,000 via QCD
• Taxable RMD: $20,000 (not $40,000)
• Tax savings: $4,400 (at 22% bracket)

Strategy 3: Spend RMDs

Use RMDs for Expenses:

• Don't reinvest if not needed
• Use for living expenses
• Why: Reduces other income needs

Example:

• RMD: $40,000
• Living expenses: $50,000
• Only need $10,000 from other sources: Lower other income

Strategy 4: Tax Bracket Management

Manage Total Income:

• Balance RMDs with other income
• Stay in lower bracket when possible
• Why: Minimize tax burden

Example:

• Need $60,000 income
• RMD: $40,000
• Other income: $20,000
• Vs. all from traditional: Lower tax

Strategy 5: Delay Other Income

If RMDs Are High:

• Delay other distributions
• Use RMDs first
• Why: May reduce overall tax

RMD Penalties

The Penalty

If You Don't Take RMD:

• 25% penalty on amount not withdrawn
• Reduced to 10% if corrected within 2 years
• Why: Encourages compliance

Example: RMD $40,000, only took $20,000

• Shortfall: $20,000
• Penalty: $5,000 (25% of $20,000)
• If corrected: $2,000 (10%)

How to Avoid Penalties

Take RMDs on Time:

• By December 31 each year
• First RMD by April 1 (but then two in one year)
• Why: Avoids penalties

Calculate Correctly:

• Use correct balance
• Use correct life expectancy factor
• Why: Ensures accuracy

Common RMD Mistakes

Mistake 1: Not Taking RMD

Problem: Forget to take RMD

Cost: 25% penalty

Solution: Set up automatic withdrawals

Mistake 2: Taking Too Little

Problem: Calculate incorrectly, take less than required

Cost: 25% penalty on shortfall

Solution: Double-check calculation

Mistake 3: Not Taking From Each 401(k)

Problem: Think you can aggregate 401(k) RMDs like IRAs

Cost: Penalty on missed RMDs

Solution: Take from each 401(k) separately

Mistake 4: Not Planning for Taxes

Problem: Don't set aside money for taxes

Cost: Surprise tax bill

Solution: Plan for tax on RMDs

Mistake 5: Not Using QCDs

Problem: Don't know about QCD option

Cost: Pay unnecessary taxes

Solution: Consider QCDs if charitably inclined

RMD Planning Strategies

Start Planning Early

Before Age 73:

• Consider Roth conversions
• Plan withdrawal strategy
• Why: More options before RMDs start

Annual Review

Each Year:

• Calculate RMD
• Plan for tax impact
• Consider QCDs
• Why: Adjust strategy as needed

Work with Professional

If Complex:

• Hire tax professional
• Financial planner
• Why: Expertise helps

Bottom Line

Required Minimum Distributions explained:

1. RMDs start at age 73: Must take minimum withdrawals
2. Based on account balance and life expectancy: Formula determines amount
3. Fully taxable: Ordinary income rates
4. Can increase taxes: May push into higher bracket, increase Social Security tax, trigger IRMAA
5. Planning reduces impact: Roth conversions, QCDs, strategic withdrawals

Key Takeaways:

• RMDs start at age 73: Must take minimum withdrawals from pre-tax accounts
• Fully taxable: Ordinary income rates (10-37%)
• Can increase other taxes: Social Security tax, IRMAA surcharges
• Planning reduces impact: Roth conversions, QCDs, strategic withdrawals
• Penalties are severe: 25% if you don't take RMD
• Calculate correctly: Use prior year-end balance and life expectancy table
• Review annually: Adjust strategy as needed

Action Steps:

1. Understand when RMDs start (age 73)
2. Calculate your RMD (account balance ÷ life expectancy factor)
3. Plan for tax impact (ordinary income rates)
4. Consider Roth conversions before age 73
5. Consider QCDs if charitably inclined
6. Set up automatic withdrawals to avoid penalties
7. Review strategy annually
8. Work with professional if needed

Remember: RMDs are a reality for traditional retirement accounts, but with proper planning, you can minimize their tax impact. Consider Roth conversions before RMDs start, use qualified charitable distributions if you're charitably inclined, and plan your withdrawals strategically. The key is starting early and reviewing your strategy annually.
