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

Long-term disability (LTD) insurance pays a monthly benefit that replaces part of your salary while you cannot work. Most policies replace 50 to 70 percent of your gross income before taxes. The exact amount depends on what your employer's plan says, not on how severe your condition is or how long you have been disabled.

The replacement percentage is set when the plan is designed. A common structure is 60 percent of gross pay, though some plans go as low as 40 percent or as high as 75 percent. Your employer chooses the level when they buy the insurance, so two people with the same job at different companies may receive very different amounts.

Most plans also set a maximum monthly benefit — often between $3,000 and $10,000 per month, though this varies widely. If your salary is very high, your benefit will hit that cap rather than reaching the stated percentage. A few plans have no cap, but these are uncommon in employer-sponsored coverage.

Key Takeaways

  • Long-term disability typically replaces 50 to 70 percent of your gross salary, with 60 percent being the most common level.
  • Your employer chose the replacement percentage when they purchased the plan, so you need to check your plan document to know your exact rate.
  • Most plans have a maximum monthly benefit cap, which means high earners may not receive the full percentage of their salary.
  • The benefit amount is usually based on your salary at the time you become disabled, not on your job title or medical condition.
  • Long-term disability payments are typically subject to federal income tax unless your employer paid the premiums with pre-tax dollars.

How your salary is calculated for the benefit

LTD plans measure your income in different ways depending on the plan language. Most use your average gross salary over the 12 months before you became disabled. Some use your salary at the exact moment you stopped working. A few use your highest salary in the past two years.

The plan document will specify which method applies. If you have had a recent raise, the timing matters — a plan that uses the past 12 months will include the raise, but one that uses only your current salary at the time of disability might not if the raise was very recent.

Bonuses and commissions are handled inconsistently. Some plans include them in the income calculation; others exclude them or average them over several years. If your pay includes variable income, ask your benefits administrator or plan administrator to show you in writing how they will calculate your benefit amount.

When the benefit starts and how long it lasts

Long-term disability does not begin when ready. Most plans have an elimination period (also called a waiting period) of 90 days, though some are 60 days and others are 180 days. During this time, you receive no LTD payment. Short-term disability, if your employer offers it, usually covers this gap.

Once the elimination period ends, LTD payments begin. The length of time you receive them depends on your plan. Some plans pay until age 65 or 67. Others pay for a fixed period — two years, five years, or until you reach retirement age, whichever comes first. A few pay for life, but these are rare in employer plans.

The plan document will state the benefit period clearly. This is one of the most important numbers to know, because it affects how long you can count on the income and whether you need to plan for other resources.

How taxes affect what you actually receive

The monthly benefit amount is usually stated as a gross figure, but taxes reduce what lands in your bank account. If your employer paid the premiums with pre-tax dollars (deducted from your paycheck), the LTD benefit is taxable income. You will owe federal income tax on it, and possibly state income tax and Social Security tax as well.

If you paid the premiums yourself with after-tax dollars, the benefit is usually not taxable. This is rare in employer plans but common in individual policies. Check your pay stub or benefits summary to see whether your premiums were deducted before or after tax.

Your LTD insurer will send you a 1099-R form at tax time showing the amount paid. If the benefit is taxable, you may owe a large tax bill at the end of the year unless you have taxes withheld from your monthly payment. You can request withholding when you file your claim.

Offsets and reductions that lower your payment

Many LTD plans reduce your benefit if you receive other income. The most common offset is Social Security Disability Insurance (SSDI). If you receive SSDI, your LTD benefit is reduced by the amount of your SSDI payment. Some plans offset by the full SSDI amount; others offset by 50 percent of it.

Workers' compensation is another common offset. If you are receiving workers' comp for the same condition that caused your disability, LTD will reduce your benefit by the workers' comp amount or a portion of it.

Some plans also offset for other disability income, retirement benefits, or income from part-time work. A few plans have no offsets at all. Your plan document will list which offsets explore. This is critical information — a plan that pays 60 percent of salary but offsets for SSDI may pay significantly less than you expect once you receive both benefits.

How your benefit changes if you return to work

If you return to work part-time or at a lower salary, your LTD benefit may be reduced. Some plans use a residual disability formula: they pay the difference between your pre-disability salary and your current earnings. If you earned $4,000 per month before disability and now earn $2,000, a residual plan might pay 60 percent of the $2,000 difference.

Other plans have a strict definition: you either may have access to for the full benefit or you do not, with no partial payments. These are less common but do exist. The plan document will specify whether residual disability is available and how it is calculated.

Work incentives under SSDI can affect your LTD benefit as well. If you use a work incentive like a Plan to Achieve Self-Support (PASS) to return to work while on SSDI, your SSDI benefit may change, which in turn affects your LTD offset. Coordinate with both your LTD insurer and Social Security before you return to work.

What to do if your benefit seems too low

If your LTD payment arrives and it is lower than you expected, start by requesting a benefit calculation statement from your plan administrator. This document shows exactly how they arrived at the number — the salary they used, the percentage applied, any offsets, and any deductions.

Common reasons for a lower-than-expected benefit: the plan uses a lower replacement percentage than you thought, a maximum benefit cap has been reached, an offset for SSDI or workers' comp has been applied, or taxes have been withheld. The calculation statement will show which applies to you.

If the calculation is wrong, file a written appeal with your plan administrator. If the calculation is correct but the plan terms are not what you understood, you may have grounds to dispute the plan design itself, though this is a legal matter and requires an attorney familiar with ERISA (the law governing employer benefit plans).

Frequently Asked Questions

Can I receive both long-term disability and Social Security Disability at the same time?

Yes, but your LTD benefit will be reduced by your SSDI payment. Most plans offset by the full SSDI amount, so if you receive $1,500 in SSDI, your LTD payment drops by $1,500. Some plans offset by only 50 percent. Check your plan document to see which applies to you.

What happens to my long-term disability if I get a job offer while disabled?

If your plan includes residual disability, you can work part-time and receive a reduced benefit based on the income difference. If your plan does not, you will lose the full benefit once you return to work, even part-time. Contact your plan administrator before accepting any job to understand how it affects your payments.

Is my long-term disability benefit the same as what I would receive on SSDI?

No. LTD is based on your salary and your employer's plan terms. SSDI is based on your work history and a federal formula. The two are calculated completely differently and usually result in different amounts. You may receive both, but your LTD will be reduced by your SSDI payment.

Do I have to pay taxes on my long-term disability benefit?

Only if your employer paid the premiums with pre-tax dollars. If you paid the premiums yourself with after-tax money, the benefit is not taxable. Check your pay stub to see how your premiums were deducted. Your LTD insurer will send you a 1099-R form showing whether the benefit is taxable.

What if my long-term disability benefit ends before I reach retirement age?

Your benefit period is set by your plan — it might end at age 65, after five years, or at another point. Once it ends, you receive no more LTD payments. Plan ahead by understanding your benefit period and exploring other income sources, including SSDI if you are still disabled and meet the work history requirement.
