Income protection insurance is a policy that replaces part of your paycheck when illness or injury keeps you from working. In the United States it’s sold as short-term or long-term disability insurance, and most policies pay between 40% and 70% of your pre-disability income for a set period. Three things decide what you actually get: how the policy defines “disabled,” how long you wait before benefits start, and who paid the premiums, because that last piece controls whether the money is taxable.
The Three Moving Parts of a Policy
Every policy has an elimination period, a benefit amount, and a benefit duration. Get comfortable with those three and the rest of the contract makes sense.
The elimination period is a time-based deductible. You have to be continuously unable to work for a set number of days before benefits begin. Common choices are 30, 60, 90, 180, or 365 days. The longer you’re willing to wait, the lower your premium. Ninety days is the most popular choice because it balances cost savings against the strain of going without income.
The benefit amount is a percentage of your pre-disability earnings, usually capped between 50% and 70% of gross income. Insurers write a ceiling into the policy rather than replacing your full paycheck because partial replacement plus certain tax advantages still gets most people close to their take-home pay, while preserving the incentive to return to work.
The benefit duration is how long payments continue if you stay disabled. Short-term policies pay for a few months up to a year. Long-term policies can pay for a defined number of years, often two, five, or ten, or until you reach retirement age, depending on what you selected when you bought the coverage.
Short-Term and Long-Term Coverage
Short-term disability insurance is built to bridge a temporary setback. Benefits replace 40% to 70% of salary, start within one to two weeks of a qualifying event, and last anywhere from a few weeks to about a year. Think surgery recovery, a complicated pregnancy, or a broken bone that sidelines you for a couple of months.
Long-term disability insurance picks up where short-term ends. It typically covers 50% to 70% of gross monthly income, with an elimination period of 90 to 180 days. The trade-off is duration. Long-term policies can pay for years, and some continue all the way to age 65 or 67. If your real worry is a serious condition (cancer, spinal injury, a degenerative disease) that could keep you out of work indefinitely, long-term coverage is the piece that matters.
Many employer benefits packages include both, with the short-term policy covering the first few months and the long-term policy taking over afterward. If you’re buying on your own, most financial planners prioritize long-term coverage because short-term gaps are easier to handle with an emergency fund.
How Your Policy Defines “Disabled”
The single most important clause in a disability policy is the definition of disabled. It controls whether your claim is approved or denied, and the two main standards produce very different results.
An own-occupation policy considers you disabled if you cannot perform the core duties of your specific job. A surgeon who develops a hand tremor qualifies even if she could work as a medical consultant. An any-occupation policy is far more restrictive: you only qualify if you cannot perform the duties of any job you’re reasonably suited for by education, training, or experience. Under that standard, the same surgeon would likely be denied because she could still earn a living in another medical role.
Here’s the wrinkle most people miss. Many long-term policies start with an own-occupation definition for the first two years of benefits, then switch to an any-occupation standard. That transition is where a large number of claims get terminated. You may be approved initially, collect benefits for 24 months, and then receive a letter saying you no longer meet the policy’s definition of disabled because you could theoretically do some other kind of work. Read this clause before you buy anything else.
Residual and Partial Disability
Some policies also cover situations where you can still work but at reduced capacity. A residual disability benefit pays when you return to work part-time or in a limited role and your income drops by a significant percentage, usually at least 20%, compared to what you earned before becoming disabled. The benefit is proportional to your income loss, so if you’re earning 40% less, the policy covers roughly 40% of your full benefit.
Partial disability benefits work differently. Instead of tying the payment to actual income loss, the policy pays a flat percentage, often 50%, of what you’d receive if totally disabled. The catch is that partial disability benefits typically last only six to twelve months, which makes them far less useful for a prolonged recovery.
Where People Get Coverage: Group vs. Individual
Employer-sponsored coverage is the most common way Americans get income protection. Group policies are often subsidized or fully paid by the employer, and because risk is spread across the workforce, premiums are lower. The downside is limited flexibility. Benefit amounts are usually capped at 50% to 70% of salary, benefit periods often run two to five years, and you generally cannot customize the terms.
The bigger risk with group coverage is portability. If you leave the company, your coverage ends. Some group policies allow conversion to an individual plan, but the converted policy almost always comes with higher premiums and potentially reduced benefits. If you change jobs frequently or work in a high-turnover industry, relying solely on employer coverage leaves gaps.
Individual policies cost more because premiums are based on your personal health, age, and occupation rather than a group’s average risk. But you own the policy outright. It stays in force regardless of where you work, you can choose longer benefit periods including coverage to retirement age, and you have more control over the elimination period and add-on riders. For anyone whose income would be hard to replace, an individual policy is worth the added cost.
What Isn’t Covered
No policy covers everything. Read the exclusions before you need to file, not after.
- Pre-existing conditions. Most policies exclude conditions you were treated for during a look-back period before the policy started, commonly the prior three to six months. The exclusion typically expires after you’ve been covered for one to two years without treatment for the condition.
- Self-inflicted injuries. Disabilities from intentional self-harm are excluded under nearly every policy.
- Criminal activity. Injuries sustained while committing a crime are generally not covered.
- War and terrorism. Many policies exclude disabilities caused by war, military action, or terrorism, though some offer limited coverage.
- Substance abuse. Policies often limit or exclude disabilities arising from drug or alcohol abuse, sometimes treating them similarly to mental health conditions with capped benefit periods.
The Mental Health Cap
Roughly 99% of group disability policies sold in the U.S. limit mental health-related disability payments to a maximum of 24 months, even if the condition continues to make work impossible. The Mental Health Parity and Addiction Equity Act, which requires equal treatment of mental and physical conditions in medical plans, does not apply to disability insurance.1U.S. Department of Labor. Long-Term Disability Benefits and Mental Health Disparity A few policies extend benefits past 24 months if the claimant is hospitalized as an inpatient or if the condition stems from an organic brain disease, but those exceptions are uncommon. If you have a history of depression, anxiety, or another mental health condition, this limit deserves close attention when comparing policies.
Filing a Claim
When illness or injury forces you to stop working, file as soon as possible. Most policies require you to notify the insurer within 30 to 90 days of the disability onset, though late filings may be accepted with an adequate explanation. The claim form asks for details about your condition, the expected duration of your absence, and your treating physician’s information. You’ll also need supporting medical documentation: physician statements, diagnostic test results, and treatment records that substantiate your inability to work.
After you submit, the insurer reviews the medical evidence, and this is where things slow down. Insurers may consult their own medical examiners, request additional records from your doctors, or order an independent medical examination. Some also require a functional capacity evaluation, which tests your ability to sit, stand, walk, lift, and carry to determine what work you can still do. These evaluations are common in claims involving musculoskeletal injuries or chronic pain, and the results can make or break a claim.
Once approved, benefits are paid monthly and continue for as long as you meet the definition of disabled, up to the benefit period limit. Expect periodic reassessments. Insurers routinely require updated medical records, and for long-term claims they may ask for new physician statements every few months. Missing a reassessment deadline can result in benefits being suspended, so keep close track of every document request.
The Social Security Offset
Most group long-term disability policies require you to apply for Social Security Disability Insurance (SSDI) and include an offset provision that reduces your monthly disability payment dollar-for-dollar by the amount you receive from Social Security. If your policy pays $4,000 a month and you’re awarded $1,800 in SSDI, the insurer reduces its payment to $2,200. Your total income stays the same; the insurer just shifts part of the cost to the government. Some policies even require you to reimburse the insurer for any retroactive SSDI lump sum covering months when the insurer paid the full benefit. Individual policies are less likely to include offsets, which is another reason they cost more.
If a Group Claim Is Denied
If your coverage comes through your employer, the Employee Retirement Income Security Act (ERISA) governs how claims are handled. ERISA requires your plan to give you a written explanation when a claim is denied and to offer a formal appeals process. You generally have at least 180 days to file an appeal after receiving a denial notice, and during the appeal you can submit additional medical records, written arguments, and other evidence. The plan must give you free access to all documents relevant to your case and must consider everything you submit, including evidence that wasn’t part of the original decision. The plan administrator has to respond to your appeal within 45 days for disability benefit claims.2eCFR. 29 CFR 2560.503-1 – Claims Procedure You must exhaust the plan’s internal appeals process before filing a lawsuit to recover benefits.3Office of the Law Revision Counsel. 29 USC 1132 – Civil Enforcement Individual policies purchased outside employment are not subject to ERISA and are governed by state insurance law instead.
Are the Benefits Taxable?
Whether disability benefits are taxable depends almost entirely on one question: who paid the premiums?
If you paid the premiums yourself with after-tax money, your benefits are tax-free. The IRS excludes from gross income amounts received through accident or health insurance for personal injuries or sickness, as long as the premiums were not deducted or paid by your employer on a pre-tax basis.4Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness
If your employer paid the premiums and didn’t include that cost in your taxable wages, your benefits are fully taxable as ordinary income. If you pay your share through a cafeteria plan on a pre-tax basis, the IRS treats that the same as employer-paid premiums, so benefits are taxable. When you and your employer split the cost, only the portion attributable to your employer’s contribution is taxable.5Internal Revenue Service. Life Insurance and Disability Insurance Proceeds
The practical takeaway: if your employer offers disability coverage and lets you choose between pre-tax and after-tax premium payments, choosing after-tax means smaller paychecks now but tax-free benefits if you ever file a claim. The difference matters. A policy replacing 60% of an $80,000 salary pays $48,000 a year in benefits. If that’s taxable, you might net only $36,000 to $38,000 after federal and state taxes. If it’s tax-free, you keep the full $48,000.
Self-employed people who buy an individual policy generally cannot deduct the premiums as a business expense. The upside is that benefits are received tax-free, following the same logic: you paid with after-tax dollars, so the IRS doesn’t tax the payout.6Internal Revenue Service.

What Coverage Costs
Individual disability insurance premiums generally run between 1% and 4% of your annual income. On a $75,000 salary, that’s roughly $63 to $250 per month. Where you land depends on age, health, occupation, elimination period, benefit amount, and benefit duration. A 30-year-old office worker choosing a 90-day elimination period pays far less than a 50-year-old construction supervisor wanting coverage from day 60.
Occupation is one of the biggest cost drivers. Insurers sort jobs into risk classes, and physically demanding or hazardous work carries meaningfully higher premiums. Smokers and applicants with chronic health conditions also pay more. The most effective way to lower premiums is to extend the elimination period. Choosing 180 days instead of 90 can reduce your annual cost by 15% or more, assuming you have enough savings to cover the longer wait.
Employer-sponsored group coverage is usually cheaper per person because risk is pooled across the workforce and employers often subsidize part or all of the cost. If your employer offers disability coverage, it’s almost always worth enrolling even when the terms aren’t ideal, then layering an individual policy on top if the group plan leaves meaningful gaps.
