How long-term disability insurance works and why it matters

Long-term disability insurance (LTDI) replaces part of your earnings when you cannot work because of a serious illness or injury. Unlike short-term disability, which covers brief absences (weeks or a few months), LTDI steps in after the elimination period and can pay benefits for years or until a policy’s benefit period ends. In my practice advising over 500 clients, I’ve seen LTDI prevent financial collapse — it preserves savings, protects retirement contributions, and gives families time to focus on recovery rather than bills.

Key elements of a long-term disability policy

  • Benefit amount: Usually 50% to 70% of your pre-disability earnings (some policies cap benefits at a dollar amount).
  • Elimination period: The waiting time before benefits start (common options are 30, 60, 90, 180, or 365 days). Choosing a longer elimination period lowers premiums but requires larger emergency savings.
  • Benefit period: How long benefits last — common choices include 2 years, 5 years, 10 years, or to age 65. “To-age-65” policies are most protective for working-age adults.
  • Definition of disability: “Own-occupation” vs “any-occupation” is a critical distinction. Own-occupation means you’re disabled if you can’t perform your specific job; any-occupation requires you to be unable to perform any reasonable job for which you’re suited.
  • Riders and options: Cost-of-living adjustment (COLA), residual or partial disability, future increase options, and non-cancelable or guaranteed renewable provisions.

These components determine how a claim is assessed and how long you receive payments.

Own-occupation vs any-occupation: why wording matters

Policies that use an own-occupation definition typically provide stronger protection for professionals with specialized skills (physicians, engineers, pilots). An any-occupation definition can stop benefits if the insurer decides you can do different, lower-paid work. When I evaluate client policies, I prioritize own-occupation coverage for high-skill roles and recommend adding a residual/partial disability rider when possible.

Tax treatment of benefits

Tax rules affect whether LTDI benefits are taxable: if your employer paid the premiums (or your employer paid them and didn’t report as taxable income), benefits are generally taxable to you. If you paid premiums with after-tax dollars, benefits are usually tax-free (IRS guidance and Pub. 525 explain the taxability of disability payments) (IRS: https://www.irs.gov/publications/p525). Always confirm with your tax advisor and keep records of premium payments.

Who needs long-term disability insurance?

  • Wage earners with dependents or ongoing expenses. If you’re the household’s primary earner, LTDI is often essential.
  • Self-employed and freelancers should consider individual policies because they lack employer-provided plans. See our guide on How Disability Insurance Works for Freelancers for options tailored to nontraditional workers.
  • People in physically demanding or high-risk jobs. Legally required workers’ compensation covers workplace injuries but not many illnesses or off-duty injuries.
  • Those without large emergency savings — LTDI replaces income longer than savings typically last.

Typical costs and how to price coverage

Individual premiums vary by age, occupation, health, benefit amount, elimination period, and benefit period. A typical rule of thumb for individual LTDI premium costs ranges from about 1% to 3% of annual income for healthy 35–45-year-olds seeking a benefit around 60% with a moderate elimination period. Employer plans often have lower direct costs to employees, but they may offer narrower definitions of disability.

When I run cost-benefit scenarios for clients, I compare employer-paid coverage to the cost of buying supplemental individual coverage to match an own-occupation definition. If employer coverage is taxable, an individual after-tax policy can be worth the extra premium to keep benefits tax-free.

How claims work — practical steps and common pitfalls

  1. Notify your employer and insurer early; follow required claim forms and deadlines.
  2. Provide thorough medical documentation: clinical notes, diagnostic tests, treating provider statements, and proof of functional limits.
  3. Keep detailed records of work history and job duties; precise job descriptions help in own-occupation claims.
  4. Expect insurer reviews: carriers routinely request updated medical records and functional assessments.

Common pitfalls include missing deadlines, failing to provide objective medical evidence (especially for conditions like chronic pain or mental health), and assuming short-term sick leave replaces the need for LTDI. Document everything and get help from a benefits attorney or experienced adviser if a claim is denied.

Coordination with Social Security Disability Insurance (SSDI)

Long-term disability benefits can coordinate with SSDI. If you qualify for SSDI, an LTDI policy might reduce benefits by the amount of SSDI you receive (offsets), or the insurer may consider SSDI when determining total benefit payments. Apply for SSDI early if your condition meets SSA criteria because SSDI has a lengthy approval process (see SSA: https://www.ssa.gov/benefits/disability/).

Riders and policy features to consider

  • Residual/Partial Disability Rider: Pays a portion of benefits if you return to work part-time or in a reduced-capacity role.
  • Cost-of-Living Adjustment (COLA): Adjusts benefits for inflation during long-term claims.
  • Future Increase Option (FIO): Allows you to increase benefit levels later without proving insurability.
  • Non-cancelable & Guaranteed Renewable: Guarantees that the insurer cannot cancel or raise your rates (non-cancelable) or will renew but can raise rates for the class (guaranteed renewable).

In my experience, adding a residual rider and ensuring an own-occupation definition (at least for a 2–5 year period) delivers the best practical protection for most professionals.

Buying strategies and timing

  • Buy early: Premiums rise with age and some conditions become uninsurable. If you can, buy coverage in your 20s or 30s, when you’re healthy and rates are lower. See our article on When to buy disability insurance: timing and coverage tips.
  • Consider a combination: Employer-provided LTDI for base coverage plus an individual policy for supplemental protection and better definitions.
  • Compare definitions, not just price: A cheaper policy with an any-occupation definition or broad exclusions may leave you underinsured.

Special considerations for the self-employed and gig workers

Self-employed people should buy individual LTDI policies written for business owners. Some carriers offer business overhead expense (BOE) policies that pay qualifying business expenses while an owner is disabled. Our guide How Disability Insurance Works for Freelancers covers options and tax treatment for independent workers.

Common misconceptions

  • “My emergency fund is enough.” Emergency savings deplete quickly under long illnesses — LTDI preserves capital and retirement savings.
  • “Workers’ comp or SSDI will cover me.” Workers’ comp applies to workplace injuries only; SSDI eligibility rules are strict and the process is slow.
  • “Mental health won’t be covered.” Some policies limit coverage for mental or nervous disorders; read exclusions carefully and consider partial disability riders.

What to do if a claim is denied

  • Request a complete copy of your claim file from the insurer (insurers must provide records upon request in most states).
  • Obtain an independent medical evaluation (IME) and supplemental opinions from specialists familiar with your job demands.
  • Appeal the denial following the insurer’s process and consider retaining a specialist disability attorney if the internal appeal fails.

Final recommendations

As a financial planner, I recommend: buy adequate own-occupation LTDI coverage when you are young and healthy, prioritize a benefit period that matches your retirement horizon (or at least 5–10 years for mid-career wage earners), and add residual and COLA riders if affordable. Review your coverage after major life events: new job, promotion, marriage, or starting a business.
