What disability income insurance is

Disability income insurance pays a monthly benefit, usually a percentage of your income, if you become sick or injured and can’t work. You pay premiums while you’re healthy; if you become disabled, benefits begin after a waiting period (the elimination period) and continue for as long as you remain disabled, up to the end of the benefit period.

Coverage comes in short-term and long-term forms, and through an employer (group coverage) or bought on your own (individual coverage). Your premium depends mainly on your income and benefit amount, your occupation, the benefit period, the elimination period, and the riders you choose.

Individual vs. group coverage

Many professionals have group long-term disability through an employer. It can be a useful base, but group plans often cap the monthly benefit, may switch to a stricter definition of disability after a set period, usually end when you leave the job, and generally pay taxable benefits if your employer pays the premium. An individual policy belongs to you: it goes with you if you change jobs, and its definitions and benefits are fixed in the contract when you buy it.

Definitions of disability

The definition of disability in your contract decides whether the policy pays. From most to least protective:

Own occupation: pays if you can’t perform the material and substantial duties of your own occupation, even if you work in another field. Usually the most expensive.
Modified own occupation: pays if you can’t perform the duties of your own occupation and you are not working in another occupation.
Any occupation: pays only if you can’t perform the duties of any occupation for which you are reasonably suited by education, training or experience.
Social Security definition: the strictest standard. You must be unable to do any substantial gainful activity because of a medically determinable physical or mental impairment expected to last at least 12 months or to result in death. Social Security Disability Insurance (SSDI) also has a five-month waiting period before benefits begin.

Many policies, especially group plans, use an own-occupation definition for the first two years and an any-occupation definition after that.

Benefit period and elimination period

The benefit period is how long benefits can continue: from a few years to age 65 or 67. Longer benefit periods cost more. The elimination period is how long you must be disabled before benefits start. Long-term policies commonly use 90 days; longer elimination periods lower the premium if you have savings to cover the gap.

Short-term disability coverage typically starts after 7 to 30 days and may last around 26 weeks, with long-term coverage taking over after that.

Riders worth understanding

Residual or partial disability: pays a partial benefit if you can work but earn less because of your disability.
Future increase option: lets you buy more coverage later as your income grows, usually without new medical underwriting.
Cost-of-living adjustment (COLA): increases benefits during a long claim to help keep pace with inflation.
Non-cancelable and guaranteed renewable: the insurer can’t cancel the policy or raise your premium as long as you pay it, up to the age stated in the contract.

How much coverage you need

At a minimum, coverage should replace the income you’d lose. A disability often adds expenses too, so the financial strain can be greater than expected. Three common ways to estimate your need:

Income protection: replace a target level of future income.
Cash flow: keep enough coming in to cover expenses without drawing down savings.
Income gap percentage: replace a set share of income. Insurers typically limit total coverage to roughly 60% to 80% of earned income, depending on income level and other coverage you have.

How benefits are taxed

Tax treatment depends on who paid the premiums and how. If your employer paid the premiums, or you paid them with pre-tax dollars, benefits are generally taxable income. If you paid premiums with after-tax dollars, benefits are generally received free of federal income tax.

This is general information, not tax advice. Tax treatment depends on your situation; consult your tax advisor.

Social Security Disability (SSDI) and your policy

Most employer group long-term disability plans reduce your benefit by any SSDI you receive. Most individual policies pay their full benefit regardless of SSDI, unless you add a rider designed to coordinate with Social Security. This is one of the biggest differences between group and individual coverage.

People receiving SSDI generally become eligible for Medicare after 24 months of SSDI entitlement.

Pregnancy

Many individual policies cover disability resulting from complications of pregnancy; a normal pregnancy and delivery is often not treated as a disability. Terms vary by insurance company, so check the policy or ask us.

Why claims are denied

Not covered: the claimant wasn’t insured under the policy on the date the disability began.
Returned to work during the elimination period, resetting or ending eligibility.
Pre-existing condition that existed before coverage began.
Not disabled under the policy’s definition, including cases where the loss of income is too small to trigger benefits.
Lack of documentation to support the claim.
Excluded condition, for example certain mental health, substance use, or self-reported-symptom conditions under some policies.
Excluded circumstances, such as work-related injuries under some policies, acts of war, committing a felony, or excluded activities like non-commercial aviation.
Misrepresentation: false or incomplete information on the application or the claim.

Accurate, complete answers on your application and choosing the right definition of disability up front are the best ways to reduce claim risk later.
