Disability Income

Per IRS Publication 907 Tax Highlights for Persons with Disabilities, page 3:

Disability Pensions

If you retired on disability, you must include in income any disability pension you receive under a plan that is paid for by your employer. You must report your taxable disability payments as wages on line 1 of Form 1040 or 1040-SR until you reach minimum retirement age. Minimum retirement age is generally the age at which you can first receive a pension or annuity if you are not disabled.

Long-Term Care Insurance

Long-term care insurance contracts are generally treated as accident and health insurance contracts. Amounts you receive from them (other than policyholder dividends or premium refunds) are generally excludable from income as amounts received for personal injury or sickness. See Pub. 525.

Per IRS Publication 525 Taxable and Nontaxable Income, page 4:

Sick Pay. Pay you receive from your employer while you're sick or injured is part of your salary or wages. In addition, you must include in your income sick pay benefits received from any of the following payers:

  • A welfare fund
  • A state sickness or disability fund
  • An association of employers or employees
  • An insurance company, if your employer paid for the plan

Cafeteria plans. In most cases, if you're covered by an accident or health insurance plan through a cafeteria plan, and the amount of the insurance premiums wasn't included in your income, you aren't considered to have paid the premiums and you must include any benefits you receive in your income. If the amount of the premiums was included in your income, you're considered to have paid the premiums and any benefits you receive aren't taxable.
