Many couples unintentionally leave a substantial amount of Social Security income on the table because they misunderstand when to file and how spousal benefits actually work. Financial planners often refer to this as the “$100,000 Spousal Timing Mistake.”
The mistake usually happens when couples claim benefits too early or misunderstand how spousal benefits are calculated, permanently locking in a reduced benefit.
Below is a clear explanation of the strategy and how the mistake occurs.
The $100,000 Spousal Timing Mistake
A Common Social Security Filing Error
The mistake occurs when:
• The lower-earning spouse files too early (often at 62)
• The couple assumes they can switch to the full 50% spousal benefit later
• They don’t realize that early filing permanently reduces the spousal portion
Because the reduction lasts for life, the loss can easily exceed $100,000 over retirement.
Step 1 — Understanding the Spousal Benefit Formula
Maximum spousal benefit = 50% of the worker’s Full Retirement Age (FRA) benefit
For people born 1960 or later, FRA = 67.
Example:
| Husband FRA benefit | $3,000 |
|---|---|
| Maximum spousal benefit | $1,500 |
But that $1,500 is only available if the spouse waits until FRA (67).
Step 2 — What Many Couples Assume (Incorrectly)
Many couples believe this strategy works:
- Wife claims her own benefit at 62
- When husband retires at 67 or 70
- She switches to the full spousal benefit
Unfortunately, that is not how Social Security works anymore.
Because of the deemed filing rule, the early claim permanently reduces the spousal benefit.
Step 3 — Example of the Mistake
Couple Example
Husband FRA benefit: $3,000
Maximum spousal benefit: $1,500
Wife’s own benefit: $500
Scenario A — Wife Claims at 62
At 62 she receives:
$500 per month
Later when husband files:
The spousal portion is reduced permanently.
Her benefit becomes about:
$1,050
instead of $1,500.
Scenario B — Wife Waits Until FRA
If she waits until 67, she receives the full spousal benefit:
$1,500
Lifetime Impact of the Mistake
Difference per month:
$1,500 − $1,050 = $450
Difference per year:
$5,400
If retirement lasts 25 years:
$5,400 × 25 = $135,000 lost
This is why planners call it the $100,000 timing mistake.
Why This Happens
Before 2016, a strategy called “file and suspend” allowed spouses to:
• Claim a spousal benefit
• Delay their own benefit to grow
Congress eliminated that strategy under the Bipartisan Budget Act of 2015.
Today, most people are subject to deemed filing, which combines the benefits automatically.
The Key Timing Principle
The lower-earning spouse should often consider:
Waiting until Full Retirement Age to claim spousal benefits.
That ensures they receive the full 50% benefit.
A Better Strategy for Many Couples
A common optimized strategy is:
Higher-earning spouse
Delay benefits until age 70
Why?
Benefits increase 8% per year after FRA.
Example:
| Age | Benefit |
|---|---|
| 67 | $3,000 |
| 70 | $3,720 |
This also increases the survivor benefit.
Lower-earning spouse
Often claim at FRA (67) to receive the full spousal benefit.
Survivor Benefit — The Hidden Factor
When one spouse dies, the survivor receives the larger benefit.
Example:
| Husband benefit at 70 | $3,720 |
| Wife spousal benefit | $1,500 |
If husband dies first:
Wife receives $3,720 for life.
This is why delaying the higher earner’s benefit can be extremely valuable.
When Claiming Early Might Still Make Sense
The strategy depends on personal circumstances.
Claiming early may make sense if:
• Health concerns shorten life expectancy
• Immediate income is needed
• Both spouses have similar benefits
• The couple lacks retirement savings
Warning Signs of the $100K Mistake
Couples may be making this mistake if they say:
• “Let’s just take Social Security at 62.”
• “She can switch to half of mine later.”
• “We’ll take the money now and adjust later.”
In most cases, those assumptions are incorrect.
Quick Decision Checklist
Before filing, couples should review:
✔ Each spouse’s FRA benefit
✔ Age difference between spouses
✔ Expected longevity
✔ Survivor income needs
✔ Tax and Medicare IRMAA implications
Final Perspective
Social Security is one of the largest retirement income sources for many Americans.
A simple timing mistake — claiming spousal benefits too early — can reduce lifetime income by six figures.
Understanding when to file and when to wait is often the difference between:
• maximizing benefits
or
• locking in a permanent reduction.
