Residual Disability, Social Security Offset, and a Change in the Definition of Disability
Dr. Chen, an oral surgeon, is 41 and earns $24,000 a month after business expenses. Her individual disability policy pays $8,000 a month after a 90-day elimination period, defines disability as own occupation for 24 months and any occupation thereafter, includes a residual disability rider requiring at least a 20% income loss and paying proportionally, and includes a Social Insurance offset rider that reduces the benefit by any SSDI received. Premiums are paid personally with after-tax dollars. In March she injures her right hand, stops operating, and after two surgeries begins teaching part time at a dental school, cutting her schedule to 12 hours a week. Her monthly income falls to $9,000. Her elimination period is satisfied on June 1, and in June SSDI approves $2,600 a month.
1. Compute the monthly benefit payable once the elimination period is satisfied, showing the order of the proportional calculation and the offset.

Step by step
- Elimination period: 90 days satisfied June 1, so benefits begin with June.
- Own-occupation test: satisfied. She cannot perform the material duties of an oral surgeon; part-time teaching does not change that during the first 24 months.
- Residual calculation (loss ratio): ($24,000 - $9,000) / $24,000 = 62.5% income loss, above the 20% threshold, so the rider pays proportionally: 62.5% x $8,000 = $5,000.
- Social Insurance offset: $5,000 - $2,600 SSDI = $2,400 per month.
Total picture: $2,400 from the policy + $2,600 SSDI + $9,000 earnings = $14,000 a month, about 58% of her prior income.
Two provisions to check in the contract:
- Order of operations. If the offset is applied before the proportional calculation, the result is ($8,000 - $2,600) x 62.5% = $3,375, which is very different. The policy wording controls.
- Minimum benefit floor. Many residual riders guarantee a percentage of the total benefit regardless of offset; if this policy has one, the $2,400 could be raised.
2. What changes after the 24th month of disability, and which facts determine whether she continues to be eligible?
Read the worked answer
At month 25 the definition shifts from own occupation to any occupation, a much harder test.
- She must then be unable to perform the duties of any occupation for which she is reasonably fitted by education, training, and experience - not merely unable to operate.
- The controlling facts: she already teaches 12 hours a week, demonstrating residual work capacity in a related and well-paid field (dental education, consulting, chart review, expert testimony). If the insurer concludes she could do that full time, total disability ends.
- The realistic outcome is a shift to residual benefits rather than total disability: she is working, and if her income loss stays at or above 20%, the proportional benefit continues - but only if the residual rider survives the change in definition, which must be confirmed.
- Her earnings are the lever. If part-time income rises enough that the loss falls below 20%, no residual benefit is payable that month; if she returns to full surgical income, benefits stop.
- She should document the medical restrictions (hand function, grip, stamina) that limit her to 12 hours, because the any-occupation analysis turns on whether the limitation is surgical-specific or general.
3. How is the benefit taxed, and does the after-tax result suggest she is adequately insured?
Read the worked answer
Taxation: Because Dr. Chen paid the premiums personally with after-tax dollars, benefits are excluded from gross income under IRC 104(a)(3). The $2,400 is received tax-free. SSDI, by contrast, becomes partly taxable once provisional income exceeds the thresholds - up to 85% can be included in gross income.
Adequacy: the after-tax replacement ratio is better than the 58% gross figure implies, but it is still short of the 70-80% most planners target, and her practice overhead, malpractice tail, and disability-related costs do not disappear.
- She is badly underinsured relative to income. $8,000 of benefit on $24,000 of monthly earnings is about 33%. Individual disability issue limits typically run 60-70% of earned income after offsets, so meaningful additional coverage is available.
- Keep premiums personally paid. If a practice entity or employer ever pays the premium, benefits become taxable - and because the offset rider subtracts gross SSDI, the after-tax result deteriorates further.
- Watch offset stacking. A second policy with its own Social Insurance offset could subtract the same $2,600 again, which can cut the combined benefit more than the illustration suggests.
