A 14-Month Disability: Offsets, Taxation, and an HSA in Limbo
Priya, 56, earns a $120,000 base salary plus a discretionary bonus. Her employer pays 100% of the premium for group long-term disability coverage: 60% of base salary, a 90-day elimination period, own-occupation for 24 months then any-occupation, an offset for Social Security disability and other income, and a $100 monthly minimum benefit. Group health is a $3,000-deductible HDHP paired with an HSA; the employer seeds $1,000 and Priya contributes $600 a month. A car accident keeps her out of work for 14 months. Social Security approves SSDI of $2,300 a month. She elects COBRA for the HDHP and keeps her $600 monthly HSA contributions while on unpaid FMLA leave.
1. Calculate the monthly LTD benefit and explain when it starts and how long the own-occupation definition lasts.

Gross benefit: 60% of $120,000 = $72,000 a year, or $6,000 a month. The discretionary bonus is excluded because the plan defines covered compensation as base salary - a point worth confirming in the certificate of coverage.
Offset: $6,000 less the $2,300 SSDI benefit = $3,700 a month. The $100 minimum is irrelevant because the net figure is far above it.
Timing: the 90-day elimination period means months 1 through 3 are unpaid. Benefits begin in month 4, so a 14-month disability produces roughly 11 months of payments - about $40,700.
Own-occupation: for the first 24 months the carrier pays if Priya cannot perform the material duties of her own occupation; thereafter the test narrows to any occupation for which she is reasonably suited by education, training, and experience. Her 14-month claim never reaches the changeover.
Two traps. First, some plans use an offset formula of 50% of gross benefit minus 50% of other income rather than dollar-for-dollar; the certificate controls, and the numbers differ materially. Second, if SSDI is awarded retroactively to cover the elimination period, the carrier will reduce past benefits and seek reimbursement of any overpayment.
2. How is the $3,700 monthly benefit taxed to Priya, and what would have changed if she had paid the premiums?
Read the worked answer
Fully taxable as ordinary income. The employer paid 100% of the LTD premium, and Priya was never taxed on that premium. The mirror-image rule of IRC 104(a)(3) and 105(a) is that benefits are taxed to the same extent the premiums were not. So the $3,700 is ordinary income, reported on a W-2 or 1099 depending on how the plan is administered, with no FICA and no mandatory withholding - she can file Form W-4S to have tax withheld voluntarily.
If she had paid with after-tax dollars, the benefits would be entirely income tax free. If the premium had been split, the exclusion would be proportional: the after-tax share of premium produces a tax-free share of benefit.
Watch the pre-tax trap. Premiums paid through a cafeteria plan with pre-tax employee dollars still produce taxable benefits. Employees often assume that because they 'paid' the premium, the benefit is tax free - it is not if the dollars were salary-reduced.
Planning point: her real replacement ratio is not 60% of base. After the SSDI offset she receives $3,700, which at a 24% marginal rate is roughly $2,812 of spendable income per month against a take-home figure based on $120,000. That gap is the case for a supplemental individual disability policy written with after-tax dollars.
3. Is Priya still eligible to contribute to the HSA on COBRA, and can the HSA pay her COBRA premiums?
Read the worked answer
Eligibility continues. HSA eligibility turns on being covered by a qualifying high-deductible health plan and not being enrolled in disqualifying coverage or entitled to Medicare. COBRA continuation of the same HDHP is still an HDHP, so she may keep contributing. (The COBRA election itself, and the mere availability of a general-purpose health FSA, are the traps - a general-purpose FSA through a spouse would disqualify her.)
The limit is a ceiling, not a per-payment test. Her $600 a month plus the employer's $1,000 seed must stay within the annual family contribution maximum. At $7,200 plus $1,000 she risks exceeding it; excess contributions draw a 6% excise tax each year they remain, and can be corrected with a timely withdrawal of the excess and its earnings.
Yes to COBRA premiums. COBRA premiums are a specific statutory exception to the rule that health insurance premiums are not qualified HSA distributions, so she can pay them from the HSA tax free - a valuable cash-flow relief while unpaid on FMLA leave.
The Medicare clock. She is 56, so Medicare is not yet an issue, but her SSDI entitlement starts a 24-month waiting period for Medicare. If the disability continues that long, she must stop HSA contributions once entitled to Medicare, and should plan a reduced or zero contribution schedule well before that date. The advisor who catches this early avoids an excise tax problem two years out.
