Long-term disability insurance replaces a portion of your income, not all of it

Long-term disability (LTD) insurance pays a percentage of your regular salary while you cannot work due to injury or illness. The amount is not a fixed dollar figure—it depends on what your employer's plan says it will replace, usually between 50% and 70% of your gross monthly income. Some plans cap the monthly benefit at a specific dollar amount, which means high earners may receive less than the stated percentage.

The payment comes from your employer's insurance carrier, not from Social Security or any government program. Your employer chose the plan and set its terms when they purchased it, so two people doing the same job at different companies may receive very different amounts. The insurance company pays the benefit directly to you, typically by check or direct deposit, for as long as your claim remains approved and you meet the plan's definition of disability.

Key Takeaways

  • Long-term disability typically replaces 50% to 70% of your gross monthly income, but your specific plan may replace a different percentage or cap the total amount.
  • Your employer's insurance carrier determines the benefit amount based on the policy they purchased, so you need to check your plan documents to know what you would receive.
  • The benefit usually begins after an elimination period (often 90 days or longer), during which you receive no payment and may use sick leave or short-term disability instead.
  • If you also receive Social Security Disability Insurance (SSDI), your LTD benefit may be reduced by the SSDI amount, depending on what your plan says.
  • Long-term disability is taxable income if your employer paid the premiums; it is tax-free if you paid the premiums yourself.

How to find your plan's specific payment amount

Your employer's human resources or benefits department has a document called a Summary Plan Description (SPD) or plan booklet. This document states the exact percentage of income your plan will replace and any maximum monthly dollar amount. Request this from HR in writing (email is fine) and ask them to highlight the section that describes the benefit amount.

The SPD will also tell you the elimination period—the number of days you must be unable to work before benefits begin. Common elimination periods are 30, 60, or 90 days. During this time, you receive nothing from the disability plan, though you may be able to use accrued sick leave or short-term disability if your employer offers it.

If you cannot locate your SPD, the insurance carrier's name appears on your pay stub or in your benefits portal. You can contact them directly and request the plan documents. They are required by law to provide them within 30 days.

What happens if you also receive SSDI

Many people receive both long-term disability and Social Security Disability Insurance (SSDI). When this occurs, your LTD benefit may be reduced by the amount you receive from SSDI—a practice called offset or coordination of benefits. Not all plans do this, so check your SPD for language about "offset," "reduction," or "coordination with other benefits."

If your plan includes an offset, the insurance company will wait for your SSDI decision before finalizing your LTD payment. Once you receive your first SSDI check, the insurance company reduces your LTD benefit by that amount. For example, if your LTD plan would pay $2,000 per month and you receive $800 per month from SSDI, your LTD payment drops to $1,200.

Some plans offset only a portion of SSDI, or they may not offset at all. This is why reading your specific plan document matters—the rules vary widely.

Tax treatment of long-term disability payments

Whether your LTD benefit is taxable depends on who paid the premiums. If your employer paid the full premium (the most common scenario), the benefit is taxable income and the insurance company will send you a 1099-R form at tax time. You must report it as income on your federal tax return.

If you paid the premiums yourself through after-tax payroll deductions, the benefit is not taxable. Some employers offer a choice: you can pay premiums yourself and receive tax-free benefits, or let the employer pay and receive taxable benefits. If you chose to pay yourself, keep documentation of those payments.

If your employer paid part of the premium and you paid part, the benefit is partially taxable. The insurance company will calculate the taxable portion and report it on your 1099-R.

How long payments continue

Long-term disability benefits continue for as long as your claim is approved and you remain unable to work under your plan's definition of disability. Some plans pay until you reach retirement age (often 65), while others pay for a set number of years (such as 2, 5, or 10 years). A few plans pay until age 70 or beyond. Your SPD will state the maximum benefit period.

The insurance company reviews your case periodically—usually every one to two years—to confirm you still meet the disability definition. If you return to any form of work, even part-time, you must report it. Depending on your plan, you may lose benefits when ready or receive a reduced benefit if you earn income above a certain threshold.

If you reach the end of your benefit period while still unable to work, payments stop. At that point, you would need to rely on other income sources, such as SSDI, retirement savings, or family support.

Differences between employer plans and individual policies

If you purchased disability insurance on your own (not through an employer), the benefit amount is whatever you chose when you bought the policy. Individual policies typically replace 50% to 70% of your income, up to a monthly maximum you selected. These policies are usually more expensive than employer plans but offer more control over the benefit amount.

Individual policies also tend to have stricter definitions of disability. An employer plan might pay if you cannot do your specific job; an individual policy often requires that you cannot do any job for which you are reasonably trained. This makes individual policies harder to claim on but more likely to pay if approved.

If you have both an employer plan and an individual policy, both may pay, but the combined benefit usually cannot exceed 70% to 80% of your income. The policies coordinate with each other to avoid overpayment.

What to do before you need to file a claim

Request your SPD now, while you are working. Read the section on benefit amounts, elimination periods, and offset rules. Write down the insurance company's name and claim phone number. If you have questions about how much you would receive, call the insurance company's customer service line—they can estimate your benefit based on your current salary.

If you become unable to work, you will need to notify your employer and the insurance company within the timeframe stated in your plan (usually 30 to 90 days). Gather medical documentation from your doctor, including diagnosis, treatment, and restrictions on work activity. The insurance company will use this to decide whether you meet their definition of disability.

Keep copies of all correspondence with the insurance company. If your claim is denied, you have the right to appeal. The appeal process is described in your SPD.

Frequently Asked Questions

Can I receive long-term disability and still work part-time?

Some plans allow partial benefits if you work part-time and earn below a certain threshold. Others require total inability to work. Check your SPD for language about "residual disability" or "partial disability." If you work, you must report all income to the insurance company or risk losing benefits.

What if my employer changes insurance carriers?

Your benefits continue under the new carrier's plan, but the benefit amount or terms may change. Your employer must notify you of any changes and provide a new SPD. If the new plan pays less, you may have a limited window to purchase individual supplemental coverage.

Does long-term disability cover mental health conditions?

Most employer plans cover mental health conditions if they prevent you from working, but some plans limit mental health benefits to a shorter period (such as 24 months) than physical conditions. Your SPD will state whether mental health is covered and any time limits that explore.

What happens to my long-term disability if I get fired?

If you are already receiving benefits when you are fired, your payments usually continue as long as you remain disabled. If you have not yet filed a claim, you generally cannot file one after leaving the company. Check your SPD for the exact rule at your employer.

How do I know if my disability plan has an offset with SSDI?

Search your SPD for the words "offset," "reduction," "coordination of benefits," or "Social Security." If you find these terms, read that section carefully. If you cannot find them, call the insurance company and ask directly whether your plan reduces LTD by SSDI.
