RMD Mistakes
Trap 1: Not Taking RMDs
The Mistake: Forget to take RMD

- Penalty: $10,000 (25% of $40,000)
How to Avoid: Set up automatic withdrawals, calendar reminders

Example: RMD $40,000, only took $30,000
- Shortfall: $10,000
- Penalty: $2,500 (25% of $10,000)
How to Avoid: Double-check calculation, use IRS worksheets
Trap 3: Not Planning for RMD Tax Impact

The Cost: Pushed into higher bracket, more Social Security taxable, IRMAA surcharges
Example:
- Before RMDs: $60,000 income, 12% bracket
- After RMDs: $100,000 income, 22% bracket
- Extra tax: $4,000+/year
How to Avoid: Plan ahead, consider Roth conversions before RMDs
Trap 4: Not Using QCDs
The Mistake: Don't know about Qualified Charitable Distributions
The Cost: Pay tax on RMDs you could donate tax-free
Example: RMD $40,000, donate $20,000
- Without QCD: Taxable $40,000, tax $8,800
- With QCD: Taxable $20,000, tax $4,400
- Savings: $4,400 (if charitably inclined)
How to Avoid: Learn about QCDs, use if charitably inclined

Example:
- Social Security: $30,000
- Other income: $40,000
- Combined income: $55,000
- Taxable Social Security: $17,000 (57%)
- Tax: $3,740 (at 22% bracket)
How to Avoid: Understand combined income formula, plan other income
Trap 2: Not Managing Other Income
The Mistake: Don't realize you can reduce Social Security tax by managing other income
The Cost: Pay more tax on Social Security than necessary
Example:
- Current: $40,000 other income, $17,000 Social Security taxable
- If reduce to $30,000: $13,000 Social Security taxable
- Savings: $880 (at 22% bracket)
How to Avoid: Use Roth withdrawals, manage income strategically
Trap 3: Taking Social Security Early
The Mistake: Take Social Security at 62 without considering tax impact
The Cost: Lower benefit + more taxable (if have other income)
Example:
- Take at 62: $20,000/year, more taxable due to other income
- Wait until 70: $35,000/year, but may be less taxable later
- Complex decision: Consider taxes
How to Avoid: Consider tax impact when deciding when to claim

- IRMAA: $140/month ($1,680/year)
- Vs. no IRMAA: Extra cost
How to Avoid: Understand IRMAA, manage MAGI
Trap 2: Not Planning for IRMAA
The Mistake: Don't realize RMDs will trigger IRMAA
The Cost: IRMAA surcharges on top of RMD taxes
Example:
- RMD increases MAGI to $220,000
- IRMAA: $140/month ($1,680/year)
- Plus RMD tax: Double hit
How to Avoid: Plan ahead, consider Roth conversions before Medicare
Trap 3: Not Appealing IRMAA
The Mistake: Don't appeal IRMAA if income dropped

Bracket Management Mistakes
Trap 1: Not Coordinating Income Sources
The Mistake: Don't coordinate withdrawals from different accounts
The Cost: Pushed into higher bracket unnecessarily
Example:
- Withdraw $50,000 from traditional IRA
- Plus $30,000 from Roth
- Total: $50,000 taxable (Roth doesn't count)
- Vs. all from traditional: $80,000 taxable, higher bracket
How to Avoid: Coordinate withdrawals, use Roth strategically
Trap 2: Large Withdrawals in One Year
The Mistake: Take large withdrawal, push into high bracket
The Cost: Pay higher tax rate
Example:
- Need $120,000 over 2 years
- Take all in Year 1: $120,000, 24% bracket, $20,000 tax
- Spread over 2 years: $60,000/year, 22% bracket, $13,200/year
- Savings: $6,400 over 2 years
How to Avoid: Smooth income, spread large withdrawals
Trap 3: Not Using Lower Bracket Years
The Mistake: Don't take advantage of low bracket years
The Cost: Miss opportunity to withdraw at lower rate
Example:
- Year 1: Low income, 12% bracket
- Don't withdraw from traditional IRA
- Year 2: Higher income, 22% bracket
- Missed opportunity: Could have withdrawn at 12%
How to Avoid: Plan withdrawals, use low bracket years
Withdrawal Sequencing Errors
Trap 1: Wrong Order of Withdrawals
The Mistake: Withdraw from wrong accounts first
The Cost: Pay more tax than necessary
Example:
- Withdraw from traditional IRA first
- Vs. Roth first: Traditional withdrawals increase Social Security tax, IRMAA
How to Avoid: Plan withdrawal order (RMDs, taxable basis, Roth, traditional)
Trap 2: Not Using Taxable Account Basis
The Mistake: Don't realize taxable account basis is tax-free
The Cost: Pay tax when don't need to
Example:
- Taxable account: $200,000 ($150,000 basis, $50,000 gains)
- Can withdraw $150,000 basis: $0 tax
- Vs. IRA withdrawal: Would pay tax
How to Avoid: Use taxable account basis first
Trap 3: Not Maximizing Roth Withdrawals
The Mistake: Don't use Roth when beneficial
The Cost: Pay tax when could use tax-free Roth
Example:
- High-income year: Use Roth (doesn't count in AGI)
- Vs. traditional: Increases AGI, more Social Security tax, IRMAA
How to Avoid: Use Roth in high-income years
State Tax Traps
Trap 1: Moving to High-Tax State
The Mistake: Move to state without considering taxes
The Cost: Thousands in state taxes
Example:
- Move from Florida (no income tax) to California (high income tax)
- $100,000 retirement income
- Extra state tax: $6,000+/year
How to Avoid: Research state taxes before moving
Trap 2: Not Understanding State Rules
The Mistake: Don't understand how state taxes retirement income
The Cost: Surprise state tax bill
Example:
- Move to state thinking no tax
- But state taxes pensions
- Surprise tax bill
How to Avoid: Research state tax rules thoroughly
Trap 3: Not Considering All State Taxes
The Mistake: Only look at income tax, ignore property/sales tax
The Cost: High property/sales tax offsets income tax savings
Example:
- State A: No income tax, high property tax
- State B: Low income tax, low property tax
- May be similar: Total tax burden
How to Avoid: Calculate total tax burden (income, property, sales)
