At high incomes, the group-LTD policy offered by your employer is almost never enough on its own, and the contract terms differentiating one individual supplementary policy from another move six-figure annual outcomes. Five points are worth getting right before you buy.
Own-occupation vs. any-occupation definition. The disability-trigger language is the single most important contract term. A true own-occupation (often called “own-occ to age 65”) policy pays the full benefit if you are unable to perform the material duties of your specific occupation as it was practiced at the time of disability, even if you can earn income in a different line of work. An any-occupation policy pays only if you cannot perform any gainful occupation for which you are reasonably suited by education, training, and experience — a substantially harder bar. The middle ground common in group plans is own-occ for 24 months, then any-occ, which is close to a worst case: full benefit while your savings would have held out anyway, then a cliff exactly when you most need the income to continue. For professional readers — physicians, surgeons, dentists, lawyers, executives, founders — the true own-occ definition through age 65 is the contract term to insist on, and it is the largest single price differentiator on the policy.
Specialty own-occupation language for medical and legal specialists. A radiologist who can no longer read scans but could in principle examine patients is not disabled under a generic own-occ policy that defines occupation as “medicine.” The fix is specialty own-occ language: the contract defines occupation as the insured’s medical or legal specialty as actually practiced. The four carriers most often associated with reliable specialty own-occ contracts in 2026 are Guardian/Berkshire, Principal, Ameritas, and MassMutual; Standard and Mutual of Omaha sometimes offer it. The specialty rider is the strongest contract feature on the market for surgeons, anesthesiologists, dental specialists, and litigators, and the underwriting is straightforward only while you are healthy — a single diagnosis after issue dramatically narrows your future options.
The group-LTD cap. Employer-provided long-term disability typically caps the monthly benefit at $10,000–$25,000, sometimes higher at large investment banks and law firms. At a $500,000 income, the 60% replacement headline rate sounds adequate ($300,000 annually, $25,000 monthly) and runs straight into the cap; at a $1.5M income, the same replacement rate is meaningless — the cap pays the same $25,000 a month whether you earn $500,000 or $5M. The fix is an individual supplementary policy underwritten on your total compensation, stacked on top of the group policy. For very high incomes, the standard market ceilings of roughly $35,000–$50,000 per month are extended through Lloyd’s of London high-limit policies that can underwrite to $75,000–$100,000 per month. Coordinate carriers via the integrated benefit limit, typically capping combined benefits at about 70% of pre-disability income.
Bonus and equity-compensation inclusion. Most group LTD contracts define “earnings” as base salary only. If 50%–80% of your total compensation is bonus and RSU vesting, the group policy replaces a fraction of true income even before the cap binds. An individual policy can underwrite against total compensation (W-2 wages plus an averaged bonus and equity-comp number, typically backed by W-2s and pay statements), bringing the effective replacement rate up to the actual income level. Reissue the policy every two to three years as your income climbs; the future increase option (FIO) rider buys the right to raise coverage without further medical underwriting, valuable for any career arc with expected income growth.
The IRS rule on disability benefits ( IRC §105, IRC §106) is mechanical: premiums paid pre-tax (employer pays, or employee pays via a pre-tax cafeteria plan) yield taxable benefits; premiums paid with after-tax dollars yield tax-free benefits. A $25,000 monthly group LTD benefit paid pre-tax nets roughly $15,000–$17,500 after federal-plus-state tax for a recipient in a high marginal bracket (the disability income stacks on top of investment income and is taxed at the marginal rate). The same benefit, premium-paid post-tax, nets the full $25,000. The economically correct move is to opt out of any employer pre-tax-premium election for LTD if your plan permits — paying the premium with after-tax payroll deduction or directly — and to purchase the individual supplementary policy with after-tax dollars by default. The premium is a fraction of a percent of income; the tax-character improvement on benefits is 30%–40% of the benefit.
The honest replacement target. At higher incomes, the conventional 60%-of-income replacement is the wrong frame. The right question is the survival-floor test from section “Antifragility: The Spending Plan as a Survival Floor”: what monthly benefit, on a tax-free basis, covers deterministic fixed costs (mortgage, payroll, tuition, insurance premiums) for the duration of a working-life disability through age 65? The answer is usually closer to 40% of gross than to 60%, because the fixed cost stack does not climb with discretionary spending and the disabled household pays no FICA, makes no further retirement contributions, and lives off already-saved capital plus the benefit stream. Set the contract amount against fixed costs, not against the percentage rate the salesperson quotes.
