Long-term disability: insurance replaces part of an employee's income when an illness or injury keeps them from working for an extended period, after a waiting period that often matches the end of short-term disability. Benefits can last for years, sometimes until retirement age.
Key takeaways
- Benefits typically begin after a 90- to 180-day elimination period.
- Plans often replace around half to 60% of earnings, reduced by Social Security disability payments.
- The definition of disability, own occupation or any occupation, decides who qualifies.
- 37% of private industry workers had access to long-term disability coverage in March 2026.
How long-term disability works
Most group LTD plans are insured and governed by ERISA. An employee files a claim near the end of the elimination period, the insurer reviews medical records, and approved claims pay a monthly benefit. Many plans pay benefits for the first 24 months if the person can't do their own occupation, then only if they can't do any occupation for which they're reasonably suited.
Benefits are usually offset by other income, such as Social Security disability insurance, workers' compensation, or state disability benefits. Insurers often require claimants to apply for SSDI and may help them do it.
As with short-term disability, taxes depend on who pays the premium. Some employers let employees pay LTD premiums after tax so that any future benefit is tax-free, a small design choice with a big effect on the claimant.
Long-term disability example
An operations director earning $9,000 a month develops a condition that keeps him out of work. His employer's LTD plan pays 60% after 180 days, with a $10,000 monthly cap. His benefit is $5,400 a month. When he's approved for SSDI at $2,800 a month, the insurer reduces its payment to $2,600, so his total stays $5,400. Because he paid premiums with after-tax dollars, none of the LTD benefit is taxable.
Why long-term disability matters for employers
Long-term disability protects employees against a risk most underestimate: losing years of earnings to illness. Access is uneven, at 37% for private industry workers versus 41% for state and local government workers in March 2026 (BLS Employee Benefits in the United States, March 2026). Offering it, even as a voluntary benefit employees pay for, closes a real gap.
For HR, LTD claims overlap with ADA obligations. An employee on LTD may still be entitled to an interactive process about returning with accommodations, and termination decisions during LTD need legal review. Coordinating insurer, leave, and accommodation records is where integrated leave management software helps.
Common long-term disability mistakes to avoid
Terminating automatically when FMLA ends
The ADA may require additional leave or accommodation. Review each case individually.
Ignoring premium tax design
Employer-paid premiums make benefits taxable. Consider letting employees choose after-tax payment.
Missing eligibility updates
Changes in hours or salary must reach the insurer to keep coverage accurate.
Not explaining offsets
Employees are often surprised when SSDI reduces their LTD benefit. Explain it up front.
