Somewhere on your pay stub there may be a line marked GTL, or “imputed income,” or “taxable life.” It adds a small amount to your gross pay that never reaches your bank account, and then you pay tax on it. Nobody gave you money. You are being taxed anyway, and the price you are being taxed on was set by the IRS, not by your employer or your insurer.
Group term life insurance is one of the most common benefits in America and one of the least examined. The 2026 Insurance Barometer Study from LIMRA and Life Happens found that 52 percent of American adults have life insurance of some kind, and for a large share of them the workplace policy is all of it. Open enrollment is when you are asked to make decisions about it, usually by clicking through a screen offering one times salary for free and three times salary for a few dollars a paycheck.
The first $50,000 is free, and the IRS prices the rest
Section 79 of the tax code lets your employer give you up to $50,000 of group term life coverage with no tax consequence to you at all. Above that line, the IRS treats the cost of the extra coverage as compensation. It goes into your taxable wages and, per the IRS, it is subject to Social Security and Medicare taxes as well.
That $50,000 threshold has sat unchanged for decades, and recent tax legislation including the One Big Beautiful Bill Act left it alone. Inflation did not. Two times salary is a common employer default, which means anyone earning more than $25,000 on that default has already crossed the line into taxable territory.
What the IRS considers the cost of that extra coverage is the odd part. It is not what your employer paid. It is a figure from a table.
Group term life insurance is taxed on a table nobody has updated since 1999
The IRS publishes what it calls the Uniform Premium Table, or Table I, in Publication 15-B. It assigns a monthly cost per $1,000 of coverage based on your age, in five year brackets. Under 25 costs five cents. Ages 25 to 29 cost six cents, 30 to 34 cost eight cents, 35 to 39 cost nine cents, 40 to 44 cost ten cents, 45 to 49 cost fifteen cents, 50 to 54 cost twenty three cents, 55 to 59 cost forty three cents, 60 to 64 cost sixty six cents, 65 to 69 cost $1.27, and 70 and up cost $2.06.
Treasury last revised those figures in 1999, in response to what it described at the time as a significant improvement in mortality. That was twenty seven years ago. Mortality has moved since, and it has not moved uniformly across ages, which means the table is not simply outdated by a constant factor. For a healthy worker in their thirties, the nine cents per thousand the IRS charges you tax on is usually higher than what a large employer’s group rate actually costs. For a sixty year old, sixty six cents is frequently a bargain against real group pricing. The tax does not track the economics. It tracks a 1999 snapshot.
Your age for this purpose is your age on the last day of your tax year. Turn 50 on December 30 and the IRS treats you as 50 for the entire year.
Your taxable income jumps on a birthday, not on a raise
The five year brackets create a cliff, and the arithmetic shows it cleanly.
Say you earn $80,000 and your employer provides two times salary, so $160,000 of coverage. Subtract the $50,000 exclusion and $110,000 is taxable, which the table counts as 110 units of $1,000.
At age 47, your rate is fifteen cents. That is $16.50 a month, or $198 a year of imputed income. At a 22 percent federal bracket plus 7.65 percent for Social Security and Medicare, you are paying roughly $59 a year in tax for coverage you never bought.
Now turn 50. Nothing about your job changed. Your salary is the same, your coverage is the same $160,000, your employer’s cost barely moved. But your rate jumps to twenty three cents, so your imputed income becomes $25.30 a month, or $303.60 a year. Your tax bill on it goes to about $90. That is a 53 percent increase in taxable income triggered by a birthday.
At 55 the rate hits forty three cents. Same salary, same coverage, $567.60 of imputed income and roughly $168 in tax. The jumps come at 50, 55, 60, 65 and 70, and each one is larger than the last.
None of this is a reason to decline coverage. It is a reason to know that the “free” benefit gets quietly more expensive on a schedule you can predict, and to check the buy up math again each time you cross a bracket rather than re-electing on autopilot.
The straddle rule can tax you on coverage you paid for entirely
A policy counts as carried by your employer, and therefore falls under Section 79, in either of two cases. The obvious one is that the employer pays some of the cost. The other is subtler: the employer arranges the premiums, and what at least one employee is charged subsidizes what at least one other employee is charged. The IRS calls this the straddle rule, and whether the rates straddle is judged against the Table I figures, not against what the insurance actually costs.
Most employers price voluntary life in age bands that do not line up perfectly with Table I, so some employees are charged more than the table says their coverage costs and some are charged less. That is a straddle. The result, in the IRS’s own words, is that the benefit is taxable even when employees are paying the full cost they are charged.
The agency’s published example makes it concrete. A 47 year old receives $40,000 of employer coverage and buys another $100,000 at her own expense. Because the optional policy is also treated as carried by the employer, only $10,000 of the combined $140,000 is excludable, and the cost of the remaining $90,000 becomes imputed income. Had that optional policy not been considered carried by the employer, none of the $100,000 would have been taxable.
Paying more of the premium yourself does not fix this. It turns entirely on how your employer structures the rate schedule, which is why two people with identical coverage at different companies get different tax outcomes. What is worth checking at enrollment is whether your voluntary coverage still beats an individual term policy once the imputed income is counted. For younger and healthier employees it often does not, and coverage bought on your own sits outside Section 79 completely.
Coverage on a spouse or dependent paid by your employer is excluded as a de minimis benefit only up to $2,000 of face amount. Above that, the same Table I applies.
The coverage ends with the job, and you get 31 days
Group term life is tied to employment, which is easy to forget when it has been deducted from your paycheck for a decade. Leave, get laid off, or drop below the hours threshold, and the policy terminates.
Insurers generally allow two ways out. Portability keeps the group term coverage going, with some of the optional benefits usually stripped. Conversion turns it into an individual permanent policy, at permanent policy prices, but with no medical underwriting required. That second point matters most for anyone whose health has changed since they were hired, because it is coverage no individual insurer would sell them.
Both come with the same deadline in most contracts: 31 days from the date coverage ends. Miss it and the right is gone, with no extensions unless the employer failed to give proper notice. Prudential’s group life materials state the window plainly, and note that if you die during that 31 day period, the insurer pays the amount you could have converted to, whether or not you filed the paperwork.
That deadline is the single most expensive thing on this page, and it is the one nobody mentions on the way out the door.
What this is actually for
Group term life insurance is a real benefit, and for most people the first $50,000 arriving tax free is straightforwardly good. What it is not is a plan. It disappears when the job does, its taxable cost rises on a schedule tied to your birthday rather than your risk, and the price the government uses to tax you was calculated when mortality tables looked different than they do now.
If your family would need the money, the coverage worth owning is the coverage that does not depend on your employer’s benefits calendar. We have written about how term and whole life policies actually differ if you want to work out what you would buy on your own. And if the GTL line on your stub is the first you are hearing of imputed income, it is worth understanding how the rest of your pay stub gets withheld too.
