Disability insurance explained: short-term vs long-term

Quick answer: Disability insurance replaces a portion of your income (typically 60-70%) if you cannot work due to illness or injury. Short-term disability covers the first 3-6 months; long-term disability kicks in after that and can last years or until retirement age. Your employer's group coverage is rarely sufficient -- most group policies cover 60% of base salary, exclude bonus and commission income, and can be cancelled. An individual policy covers the gap.

The most underinsured risk for most working adults is not death -- it is disability. A 40-year-old worker is roughly 3 times more likely to become disabled before age 65 than to die before 65. Despite this, most Americans have no individual disability coverage and rely entirely on employer-sponsored group plans with significant gaps.

What disability insurance covers

Disability insurance pays a monthly benefit when you are unable to work due to a qualifying disability -- illness, injury, or mental health condition. The benefit is typically expressed as a percentage of your pre-disability income (60-70% is standard).

What counts as "disabled": This is the most important definition in the policy. Two primary definitions:

Own occupation: You are considered disabled if you cannot perform the specific duties of your own occupation, even if you could work in another capacity. A surgeon who loses fine motor control in one hand is disabled under an own-occupation definition even if they could work as a medical consultant. This is the most favorable definition.

Any occupation: You are considered disabled only if you cannot perform ANY occupation for which you are reasonably suited by education, training, or experience. Harder to qualify; most employer group plans use a hybrid (own occupation for the first 2 years, then switching to any occupation).

When comparing policies, the definition of disability is the first thing to check.

Short-term disability (STD)

Short-term disability typically covers:

• Duration: 3-6 months (some plans up to 1 year)
• Benefit: 60-100% of pre-disability income
• Elimination period: 0-14 days before benefits begin
• Source: Usually employer-provided or supplemental payroll deduction

STD is most commonly used for: surgery recovery, childbirth recovery (including pregnancy complications), temporary illness, injury recovery.

State-mandated short-term disability: California, New York, New Jersey, Rhode Island, Hawaii, and Washington have state-mandated short-term disability programs funded through payroll taxes. If you work in these states, you have some baseline STD coverage regardless of your employer's plan.

Most STD plans coordinate with FMLA: FMLA provides 12 weeks of job-protected unpaid leave; STD provides income replacement during that period if you have coverage.

Long-term disability (LTD)

Long-term disability picks up when short-term disability ends (typically after 90-180 days, called the "elimination period" or waiting period).

• Duration: 2 years, 5 years, 10 years, or "to age 65/67" -- the most valuable option
• Benefit: 60-70% of pre-disability income
• Elimination period: 90 or 180 days (the gap you must cover with STD or savings)
• Source: Employer group plan, individual policy, or both

The elimination period gap: If your LTD plan has a 180-day elimination period and your STD plan only covers 90 days, you have a 90-day gap where you receive no disability income. Budget accordingly.

Why employer group LTD is often insufficient

60% of base salary only. Bonuses, commissions, overtime, and other variable compensation are typically excluded from the benefit calculation. A salesperson with $80,000 base + $60,000 variable comp receives LTD benefits based on $80,000, not $140,000.

Non-portable. Group LTD ends when you leave the employer. An individual disability policy follows you between jobs.

Taxable benefits. If your employer pays the LTD premiums, the benefits you receive are taxable income. If you pay the premiums with after-tax dollars, the benefits are tax-free.

Can be cancelled or modified. Employer group plans can be cancelled or reduced. An individual policy with non-cancellable terms stays in force as long as you pay premiums.

Definition of disability typically switches. Most group LTD plans use own-occupation definition for 2 years, then switch to any-occupation. An individual policy can lock in own-occupation to age 65.

Individual disability policy: when it makes sense

An individual disability policy is worth evaluating if:

• You have significant variable compensation excluded from group coverage
• You are self-employed or a high-income professional (physician, attorney, dentist, executive)
• You rely on a specific physical or cognitive skill for your work
• You want portable coverage that does not depend on your employer

Individual policies for a non-smoker in their 30s with professional occupation run $150-$300/month for adequate coverage. Premiums are higher for older buyers and for occupations with higher disability risk.

Frequently asked questions

Does disability insurance cover mental health conditions?

Most modern disability policies cover mental health conditions (depression, anxiety disorders, PTSD) with some limitations. Many group and individual policies limit mental health and substance abuse disabilities to 24 months of benefits under the LTD plan. Own-occupation individual policies may offer longer coverage. Check the specific limitation in your policy.

What is the difference between disability insurance and workers' compensation?

Workers' compensation covers injuries or illnesses that occur because of work -- on the job or as a direct result of job duties. Disability insurance covers any disability, regardless of cause. A back injury from a car accident is covered by disability insurance but not workers' comp. A workplace injury is covered by both (workers' comp is primary; disability insurance may coordinate).

How does Social Security Disability Insurance (SSDI) factor in?

Most LTD group plans and some individual policies offset benefits by any SSDI you receive. If your LTD plan pays 60% of salary and you qualify for SSDI, the LTD benefit may be reduced dollar-for-dollar by the SSDI amount. Read your policy's "other income" provisions carefully. SSDI qualification requires demonstrating inability to perform any gainful employment and has a 5-month waiting period -- the "any occupation" definition with strict qualifying criteria.

Is disability insurance tax-deductible?

Individual disability premiums paid by self-employed individuals may be deductible as a business expense in some circumstances. For W-2 employees, individual disability premiums are generally not tax-deductible but the benefits are tax-free. Employer-paid premiums are not deductible by the employee, but benefits are taxable when received.

When does my disability insurance end?

Short-term: after the covered period (90-180 days) or when you return to work. Long-term: when you return to work, when the benefit period ends (2 years, 5 years, or to age 65/67 depending on policy), or at the policy's maximum age. Well-structured policies pay to age 65 or the Social Security full retirement age.
