Disability insurance pays benefits to replace part of your income when an illness or injury keeps you from working, as defined in the policy. It is often called disability income insurance because the benefit is tied to lost earnings, not to medical bills.
Disability insurance can be bought individually or provided through an employer as part of a benefits package.
Core policy mechanics
Most disability policies are built around a few key terms:
- Definition of disability: how the policy decides whether you are disabled (for example, unable to perform your own occupation vs any occupation).
- Elimination period: the waiting period after disability begins before benefits start.
- Benefit amount: typically a percentage of income, up to a maximum monthly benefit.
- Benefit period: how long benefits can be paid if disability continues.
- Partial or residual disability: benefits that may apply when you can work but have a loss of income due to the disability.
Policies may also include limitations, exclusions, and coordination rules with other benefits.
Group vs individual disability insurance
Group coverage (employer-provided) is usually easier to obtain and may have less medical underwriting. Individual coverage is typically more customizable and can be portable if you change jobs.
How premiums are paid can also affect taxation of benefits. The details depend on the plan and jurisdiction, so it is worth understanding the basics before assuming the benefit will be tax-free.
How a disability claim is evaluated
A disability claim generally requires:
- medical evidence supporting the condition and restrictions
- occupational information about your job duties
- ongoing updates if the disability continues (treatment status, functional capacity, and income where relevant)
Disability claims can involve gray areas because the decision often depends on the policy’s definition, medical support, and how the occupation is described.
Practical example
A policy has a 90-day elimination period and a benefit period to age 65. The insured becomes disabled on January 1 and cannot perform their occupation. If the disability continues, benefits typically start after the elimination period is satisfied (around April 1), subject to the policy’s proof-of-loss and claim requirements.
