Understanding Your Income Sources
Social Security
Taxation: 0-85% taxable based on combined income
Combined Income Formula: AGI + tax-exempt interest + 50% of Social Security
2026 Thresholds (married):
- $0-$32,000: 0% taxable
- $32,001-$44,000: Up to 50% taxable
- Over $44,000: Up to 85% taxable
Strategy: Manage other income to minimize Social Security tax
Traditional IRAs/401(k)s
Taxation: Fully taxable as ordinary income
RMDs: Required at age 73
Strategy: Consider Roth conversions before RMDs, use QCDs
Roth IRAs
Taxation: Tax-free if qualified (5 years + age 59.5)
RMDs: None during owner's lifetime
Strategy: Use strategically in high-income years
Pensions
Taxation: Fully taxable as ordinary income
Strategy: Plan for tax impact
Investments
Taxation:
- Interest: Ordinary income
- Dividends: Qualified (0-20%) or ordinary
- Capital gains: Long-term (0-20%) or short-term (ordinary)
Strategy: Hold long-term, time sales strategically
Social Security Taxation Mastery
The Formula
Combined Income = AGI + Tax-Exempt Interest + 50% of Social Security
Taxable Social Security:
- Based on combined income thresholds
- 0%, 50%, or 85% of benefits
Minimizing Social Security Tax
Strategy 1: Reduce other income
- Use Roth withdrawals (doesn't count in AGI)
- Delay traditional IRA distributions
- Why: Lower combined income
Strategy 2: Time income
- Before Social Security starts
- Why: Lower combined income when Social Security starts
Strategy 3: Qualified Charitable Distributions
- QCDs don't count in AGI
- Why: Reduces combined income
RMD Management
Understanding RMDs
Start at Age 73: Must take minimum distributions
Calculation: Account balance ÷ life expectancy factor
Fully Taxable: Ordinary income rates
RMD Strategies
Strategy 1: Roth Conversions Before RMDs
- Convert to Roth before age 73
- Reduce traditional balance
- Lower RMDs
- Why: Eliminates RMDs from converted amount
Strategy 2: Qualified Charitable Distributions
- Donate RMD to charity
- Up to $105,000/year
- Not included in income
- Why: Tax-free way to satisfy RMD
Strategy 3: Plan for Tax Impact
- RMDs increase income
- May push into higher bracket
- Plan accordingly
- Why: Avoid surprises
Tax Bracket Strategy
Understanding Brackets
2026 Brackets (married):
- 10%: $0 - $23,200
- 12%: $23,201 - $94,300
- 22%: $94,301 - $201,050
- 24%: $201,051 - $383,900
- And so on...
Goal: Stay in lower brackets when possible
Bracket Management
Strategy 1: Fill Lower Brackets First
- Use taxable income to fill lower brackets
- Use tax-free income for higher amounts
- Why: Maximize lower bracket space
Strategy 2: Smooth Income
- Avoid large spikes
- Spread over years
- Why: Stay in lower brackets
Strategy 3: Coordinate Sources
- Use Roth in high-income years
- Use traditional in low-income years
- Why: Manage total income
Withdrawal Sequencing
Optimal Order
1. RMDs First (must take) 2. Taxable Account Basis (no tax) 3. Traditional IRA (strategically) 4. Roth IRA (tax-free, use last)
Why: Tax-efficient order

- Why: Lower MAGI
Strategy 2: Plan Before Medicare
- Roth conversions before age 65
- Why: Reduce traditional balance
Strategy 3: Appeal If Income Dropped
- File Form SSA-44
- If life-changing event
- Why: May reduce IRMAA
