Social Security Claiming Under Uncertainty: Moving Beyond One-Size-Fits-All Guidance

Fact-Checked Summary / Overview

This session explored both the technical mechanics of Social Security and the strategic decision-making framework for claiming benefits, emphasizing that optimal claiming is highly individualized.

Kurt Czarnowski provided a comprehensive foundation on how Social Security works—including eligibility, benefit calculation, spousal/survivor rules, taxation, and policy outlook—while Derek Tharp challenged conventional wisdom around delaying benefits, highlighting overlooked risks and behavioral considerations.

A key theme throughout was that “delay to age 70” is not universally optimal, and advisors must incorporate factors such as longevity, tax considerations, sequence risk, behavioral tendencies, and client-specific preferences. The session reinforces that Social Security planning is not purely mathematical—it is a multi-dimensional financial and behavioral decision.

Key Topics and Expanded Insights

1. Foundational Mechanics of Social Security Benefits

Key Takeaways

• Benefits are based on a worker’s highest 35 years of inflation-adjusted earnings; fewer than 35 years results in zeros reducing benefits. 
• Eligibility requires 40 credits (≈10 years of work). 
• Full Retirement Age (FRA) is 67 for those born 1960 or later, and serves as the baseline for benefit calculations. 

Planning Implications

• Missing earnings years or errors in earnings history can materially reduce benefits. 
• Advisors should regularly review client earnings records—especially for self-employed clients where corrections are time-limited. 

Advisor Insight

• Encourage all clients to establish a My Social Security account to monitor benefits and earnings accuracy. 

2. Claiming Timing: Early, FRA, and Delayed Strategies

Key Takeaways

• Claiming at 62 results in a permanent reduction (~5–6% per year). 
• Delaying past FRA increases benefits by ~8% per year until age 70. 
• Benefits do not increase beyond age 70, even if delayed further. 

Planning Implications

• The traditional “break-even” analysis assumes average life expectancy—but actual outcomes vary widely. 
• Longevity risk is central: 1 in 7 individuals age 65 lives to 95. 

Practical Example

• A client delaying from 67 to 70 may need to live into their late 80s or beyond to “break even,” depending on assumptions. 

Advisor Insight

• Timing decisions should incorporate: 
  • Health status 
  • Family longevity 
  • Portfolio withdrawal needs 
  • Behavioral preferences 

3. Flexibility Tools: Undoing or Adjusting Decisions

Key Takeaways

• Clients can withdraw a claim within 12 months and repay benefits (once per lifetime). 
• After FRA, clients can use voluntary suspension to earn delayed credits without repayment. 

Planning Implications

• Social Security decisions are not entirely irreversible, providing valuable flexibility. 
• Suspension strategies can be used to optimize benefits mid-retirement. 

Advisor Insight

• These tools are underutilized and can provide significant planning optionality. 

4. Spousal, Divorced, and Survivor Benefits

Key Takeaways

• Spousal benefits = up to 50% of the worker’s FRA benefit. 
• Survivor benefits = 100% of the deceased spouse’s benefit. 
• Divorced spouses must meet: 
  • 10-year marriage requirement 
  • Unmarried status (with exceptions for survivors) 

Important Distinction

• Survivor benefits allow claim sequencing (e.g., survivor first, own later)—a key planning opportunity. 

Advisor Insight

• Survivor benefits often represent the largest long-term income shift and must be planned proactively. 

5. Taxation and Medicare (IRMAA) Considerations

Key Takeaways

• Up to 85% of Social Security benefits are taxable depending on income thresholds. 
• Thresholds ($25k single / $32k joint) are not indexed for inflation, increasing tax exposure over time. 

Planning Implications

• Social Security interacts with: 
  • Roth conversions 
  • Required Minimum Distributions (RMDs) 
  • IRMAA (Medicare premiums) 

Advisor Insight

• Delaying benefits can create tax planning windows, especially for Roth conversions. 

6. Working While Claiming Benefits

Key Takeaways

• Before FRA: 
  • Earnings above ~$24,480 reduce benefits. 
• At FRA: 
  • No earnings limit applies. 

Important Nuance

• Withheld benefits are not lost—they result in higher future benefits. 

Advisor Insight

• Work decisions and claiming strategies should be coordinated, not treated separately. 

7. Social Security as a Retirement Income Foundation

Key Takeaways

• Replaces approximately: 
  • ~55% of income for low earners 
  • ~40% for average earners 
  • ~34% for high earners 

Planning Implications

• Social Security is a base income layer, not a full replacement strategy. 

Advisor Insight

• Planning should integrate: 
  • Portfolio withdrawals 
  • Guaranteed income sources 
  • Longevity protection 

8. Risks of Delaying Social Security (Tharp Framework)

Key Takeaways

Derek Tharp identified 8 underappreciated risks of delay:

1. Mortality risk 
2. Sequence of returns risk 
3. Policy risk 
4. Opportunity cost 
5. Regret risk 
6. Health span risk 
7. Spending optionality 
8. Underspending risk 

A. Mortality & Regret Risk

• Early death can result in lost lifetime benefits. 
• Behavioral regret may outweigh mathematical optimality. 

B. Sequence of Returns Risk

• Delaying requires portfolio withdrawals early in retirement, increasing vulnerability to market downturns. 

Example:

• A retiree delaying benefits during a downturn may: 
  • Deplete portfolio faster 
  • Lose long-term flexibility 

C. Opportunity Cost

• Delaying benefits requires spending other assets, which may have higher expected returns. 

D. Health Span Risk

• Money earlier in retirement may have higher utility due to: 
  • Better health 
  • Ability to travel and enjoy experiences 

E. Spending Behavior & Underspending

• Clients tend to: 
  • Spend Social Security more freely 
  • Be reluctant to draw from portfolios 

Advisor Insight

• The decision is not just financial—it is behavioral and experiential. 

9. Discount Rate Debate and Decision Framework

Key Takeaways

• No universally correct discount rate exists. 
• Two major approaches: 
  • Risk-based (TIPS-like) 
  • Opportunity cost (portfolio return) 

Planning Implications

• Advisors should use client-specific discount rates, not generic assumptions. 

Advisor Insight

• Incorporate: 
  • Portfolio composition 
  • Behavioral preferences 
  • Risk tolerance 

10. Long-Term Solvency of Social Security

Key Takeaways

• Full benefits projected through 2033, then ~81% thereafter without reform. 

Planning Implications

• Reform is likely before depletion: 
  • Tax increases 
  • Benefit adjustments 
  • Retirement age changes 

Advisor Insight

• Avoid extreme assumptions (e.g., “benefits will disappear”) 
• Use reasonable stress-testing scenarios 

Practical Advisor Takeaways

• Avoid “delay to 70” as default advice—individualize decisions 
• Incorporate: 
  • Longevity and health 
  • Portfolio risk and sequence risk 
  • Tax and IRMAA implications 
  • Behavioral tendencies 
• Use flexibility tools: 
  • Withdrawal of application 
  • Voluntary suspension 
• Emphasize: 
  • Earnings record accuracy 
  • Survivor planning 
  • Tax-efficient income sequencing 
• Frame decisions using both financial and behavioral lenses

Final Thought

The most important takeaway from this session is that Social Security claiming is not a one-size-fits-all decision. The optimal strategy depends on a combination of financial math, personal preferences, health, risk tolerance, and behavioral tendencies. Advisors who integrate all of these dimensions can deliver significantly more value than those relying on simplified rules of thumb.
