LTD buy-up coverage is an optional, employee-paid addition to your employer’s long-term disability plan that raises the share of income the policy would replace if illness or injury kept you out of work. Base employer plans commonly replace around 60% of pre-disability earnings; a buy-up typically pushes that to roughly 66.67% or 70%.1MetLife Worldwide Benefits. Buy-Up Long Term Disability Because you pay the buy-up premium yourself with after-tax dollars, the benefits attributable to that portion come to you tax-free, which is the single biggest financial reason to consider it.
What the Buy-Up Actually Adds
Most employer-sponsored LTD plans include a base layer the company pays for. Across private industry, the median replacement rate for those base plans is 60% of annual earnings.2U.S. Bureau of Labor Statistics. Disability Insurance Plans: Trends in Employee Access and Employer Costs Some employers set it lower, at 40% or 50%, to hold costs down.
The buy-up closes that gap. If your employer’s base covers 40%, you might purchase an additional 20% or 26.67% to reach a 60%, 66.67%, or 70% total.1MetLife Worldwide Benefits. Buy-Up Long Term Disability The premium for that extra slice comes out of your paycheck, not your employer’s benefits budget.
The Tax Advantage
The tax treatment of disability benefits depends on who paid the premium and with what kind of dollars. Benefits paid for by your employer (or paid through a pre-tax cafeteria plan) are taxable income when you receive them.3Office of the Law Revision Counsel. 26 USC 105 – Amounts Received Under Accident and Health Plans Benefits attributable to premiums you paid with after-tax dollars are excluded from gross income.4Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness
That difference is larger than it looks. If you’re in the 24% federal bracket and your state taxes income too, a $3,000 tax-free monthly benefit puts roughly the same cash in your pocket as a $4,000 taxable one.
When a claim pays out under a combined plan, the taxability splits proportionally. If your employer paid premiums covering half the total benefit and you paid the other half with after-tax money, half your check is taxable and half is tax-free.5Internal Revenue Service. Employer’s Supplemental Tax Guide (Publication 15-A)
Check the Benefit Cap Before You Buy
The replacement percentage is only half the picture. Every LTD plan also has a maximum monthly benefit, a hard dollar ceiling the policy will pay regardless of your salary. A plan might promise 60% of income but cap the payout at $10,000 a month. On a $250,000 salary, 60% would be $12,500, but you’d receive $10,000.
Some buy-up options raise that dollar cap along with the percentage. The MetLife plan referenced above moves the maximum from $6,000 at the core level to $10,000 with the buy-up.1MetLife Worldwide Benefits. Buy-Up Long Term Disability Other plans raise the percentage but keep the cap in place. If your base benefit already hits the ceiling, buying up a higher percentage adds no dollars to your check. Confirm what the buy-up does to the cap before enrolling.
Your actual benefit will also be reduced by offsets. Nearly all group LTD policies reduce payments dollar-for-dollar against Social Security Disability Insurance, workers’ compensation, and sometimes state disability benefits or injury settlements. If your LTD benefit is $4,000 and Social Security approves you for $1,500, the insurer pays $2,500 and the combined total stays at $4,000. Most policies require you to apply for Social Security disability so these offsets can take effect.
Enroll During Your First Eligibility Window
The cleanest path into buy-up coverage is signing up when you’re first eligible as a new hire. Enrollment at that point is typically guaranteed issue: the insurer accepts you without reviewing medical history or requiring an exam.
Enroll later, and the insurer will usually require Evidence of Insurability, a review of your medical records and current health. Approval is not automatic. The insurer can accept, deny, or approve you with restrictions. The same review can apply if you try to elect coverage above a certain guaranteed issue limit even during your first window. If you’re denied, you keep the base coverage your employer provides, but the buy-up at standard terms is off the table.
Waiting a year to “see if you need it” can be the difference between automatic approval and a medical review you might not pass.
What the Buy-Up Doesn’t Change
Buy-up coverage raises your percentage and often your cap. It does not shorten the waiting period, erase pre-existing conditions, or follow you if you leave the job.
Elimination period. Every LTD plan has a waiting period, usually 90 or 180 days, before benefits begin. The buy-up portion almost always shares the same elimination period as the base plan. In the MetLife example, both the core and buy-up tiers use 90 days.1MetLife Worldwide Benefits. Buy-Up Long Term Disability You’ll need savings, short-term disability coverage, or accrued leave to bridge those first three to six months.
Pre-existing condition exclusion. Buy-up coverage frequently comes with one. The insurer examines a lookback period, typically three to six months before your coverage started, for any treatment, testing, or medication. If a condition was treated during that window and you file a claim for it within an exclusion window (usually 12 months of coverage), the insurer can deny. Together they produce what the industry calls a “3/12” or “6/12” rule. Guaranteed issue waives the underwriting review, not the pre-existing exclusion itself. People who assume guaranteed approval means immediate coverage for everything are often surprised by this.
Portability. When you leave your employer, group LTD coverage, including the buy-up, generally ends. Disability coverage is not eligible for COBRA continuation; COBRA applies only to group health plans.6U.S. Department of Labor. Continuation of Health Coverage (COBRA) Some insurers offer a conversion option to an individual policy, but not all group plans include that right, and individual policies tend to cost more and may come with new underwriting. If you’re already receiving benefits when you leave, that claim typically continues under the terms in effect when the disability began.
How Your Plan Defines “Disabled”
Benefit amount matters, but so does the definition that gets you to the check. Most group LTD policies use a two-phase definition. For an initial period, commonly 24 months, you’re disabled if you can’t perform the duties of your own occupation. A surgeon who can no longer operate but could work a desk job still qualifies.
After that initial period, the standard tightens to “any occupation”: you’re disabled only if you can’t perform any job for which you’re reasonably qualified by education, training, or experience. That same surgeon, if able to teach or consult, would lose benefits. This transition is the single biggest reason long-term claims get terminated, and most people don’t learn about it until it happens.
Some plans shift as early as 12 months or as late as 48 months, so check your specific policy. A handful of buy-up options from certain carriers extend the own-occupation period or upgrade to a “true own occupation” definition that doesn’t require you to be idle from all work. The upgrade costs more but can matter for specialized professionals whose skills don’t transfer easily.
Benefit Duration
LTD benefits don’t last forever. The most common maximum benefit periods are to age 65 or age 67, though some plans use fixed durations of 2, 5, or 10 years. The buy-up portion typically follows the same duration as the base.
If a Claim Is Denied
Employer-sponsored group LTD plans, including buy-up coverage, fall under the federal Employee Retirement Income Security Act. ERISA sets the rules for how insurers handle claims and what recourse you have when they say no.
The insurer generally has 45 days to make an initial decision, with an extension available if more medical information is needed. A denial has to come in writing and must reference the specific plan provisions the insurer relied on. You then have at least 180 days to file an appeal, and someone other than the original decision-maker must review it.
Some plans require two rounds of internal appeals before you can sue in federal court. The stakes of those internal appeals are high: in an ERISA case, a judge typically looks only at the evidence that was in the administrative record during the appeals process. New medical opinions introduced for the first time in court are generally excluded. The internal appeal is your real chance to build the record, and treating it casually is the most expensive mistake people make with a denied LTD claim.
