This imputed income calculator for group-term life over $50,000 uses the official IRS Uniform Premium Table I to compute the taxable value of employer-paid life insurance above the $50,000 exclusion for 2026. The first $50,000 of coverage is tax-free; the cost of the excess is added to your W-2 (Box 12 code C) and taxed for Social Security, Medicare, and income tax — even though you receive no cash. Enter your coverage, age, and bracket to see your exact imputed income and the extra tax.
When your employer provides group-term life insurance, the first $50,000 of coverage is tax-free. But the cost of any coverage above $50,000 is treated as imputed income — a non-cash benefit that the IRS taxes as if it were wages. You never receive this money; it simply appears on your W-2 (often in Box 12, code C) and is subject to Social Security, Medicare, and income tax. This calculator uses the official IRS Uniform Premium Table I to compute exactly how much imputed income lands on your paycheck for 2026.
Under Internal Revenue Code Section 79, employer-paid group-term life coverage up to $50,000 is excluded from your taxable income entirely. The taxable benefit only begins on the 50,001st dollar. So if your employer gives you $50,000 or less, your imputed income is zero. The moment coverage exceeds $50,000 — common with "2× salary" or "3× salary" policies — the excess generates imputed income calculated not by what the employer actually paid, but by the IRS's standardized age-based table.
The IRS sets a uniform monthly cost per $1,000 of excess coverage, rising with age. These standardized rates — not your employer's real premium — drive the calculation.
| Age (at year-end) | Cost per $1,000 of excess coverage, per month |
|---|---|
| Under 25 | $0.05 |
| 25 to 29 | $0.06 |
| 30 to 34 | $0.08 |
| 35 to 39 | $0.09 |
| 40 to 44 | $0.10 |
| 45 to 49 | $0.15 |
| 50 to 54 | $0.23 |
| 55 to 59 | $0.43 |
| 60 to 64 | $0.66 |
| 65 to 69 | $1.27 |
| 70 and over | $2.06 |
Suppose your employer provides $150,000 of group-term life coverage and you are 46 at year-end, covered all 12 months, in the 22% federal bracket.
| Step | Calculation | Result |
|---|---|---|
| Excess over $50,000 | $150,000 − $50,000 | $100,000 |
| Units of $1,000 | $100,000 ÷ 1,000 | 100 |
| Table I rate (age 45-49) | $0.15 / month | — |
| Imputed income (annual) | 100 × $0.15 × 12 | $180.00 |
| FICA on imputed (7.65%) | $180 × 0.0765 | $13.77 |
| Federal income tax (22%) | $180 × 0.22 | $39.60 |
| Total extra tax on the benefit | — | $53.37 |
Notice you are taxed on just $180, not on $150,000. The imputed-income concept taxes the value of the perk, which the IRS table prices very cheaply for younger workers and steeply for older ones.
The same $100,000 of excess coverage generates wildly different imputed income by age: about $60/year at age 30 ($0.08), $180/year at age 46 ($0.15), $516/year at age 56 ($0.43), and $1,524/year at age 66 ($1.27). Because life insurance is riskier to provide as you age, the IRS table climbs steeply — so older employees with large employer policies can see meaningful imputed income, while younger employees barely notice it. The calculator selects the correct band automatically.
If you pay for part of your group-term coverage with after-tax dollars, those contributions directly offset the imputed income dollar-for-dollar. For example, if your Table I cost is $180 but you contribute $120 after-tax through payroll, only $60 is imputed. (Pre-tax contributions through a cafeteria plan do not reduce imputed income.) Enter any after-tax contribution in the calculator to net it against the imputed amount.
Group-term life imputed income is included in Boxes 1, 3, and 5 of your W-2 (federal wages, Social Security wages, and Medicare wages) and separately itemized in Box 12 with code C. Because it is folded into your taxable wages, it slightly increases your withholding throughout the year. You do not get a separate bill; the tax is collected via normal payroll withholding, which is why the benefit quietly reduces your take-home even though no cash benefit was received.
Employer-provided life insurance on a spouse or dependents follows different, often stricter rules: coverage over $2,000 on a dependent can make the entire amount imputed (the $50,000 exclusion applies only to coverage on the employee). This page focuses on coverage on your own life; if your employer pays for spouse/dependent coverage above the de minimis threshold, additional imputed income may apply that this calculator does not model.
Although imputed income is small relative to salary, it does three things to your paycheck: it raises your taxable wages, increases FICA and income-tax withholding, and can marginally affect benefits tied to W-2 wages. For most employees the impact is a few dollars per pay period; for a 60-something with a large multiple-of-salary policy it can be noticeable. The calculator shows the annual figure — divide by your number of pay periods to see the per-check effect.
The tool subtracts the $50,000 exclusion from your total employer-paid coverage to find the excess, divides by 1,000 to get coverage units, looks up the IRS Table I monthly rate for your age band, and multiplies by the number of months covered to get annual imputed income. It then subtracts any after-tax contributions, and applies FICA (7.65%) and your marginal federal bracket to show the actual extra tax. All Table I rates and the $50,000 exclusion are the official IRS figures under IRC Section 79.
This calculator is for employees with employer-paid life insurance above $50,000 who see a mysterious "GTL," "imputed income," or Box 12 Code C entry on their pay stub or W-2 and want to understand it. It is also useful for HR and payroll professionals verifying their Section 79 calculations, and for anyone deciding whether to keep, decline, or supplement employer life coverage based on the small but real tax cost.
Group-term life over $50,000 is one of several "imputed income" fringe benefits the IRS taxes without paying you cash — others include personal use of a company car, employer-paid domestic-partner health coverage, and certain gym or education benefits over the exclusion limits. They share the same mechanic: the value of the perk is added to taxable wages. This page covers the group-term life version, which is by far the most commonly encountered and the one most often misunderstood on a pay stub.
If your coverage amount changes during the year — for example after a raise that bumps a "2× salary" policy, a mid-year enrollment, or a termination — the imputed income is computed month by month using the coverage in force and your age in each month. The IRS rule looks at coverage on the last day of each month. The calculator lets you enter the number of months covered so you can prorate a partial year; for changing coverage amounts, run the tool separately for each coverage level and add the results. Your employer's payroll system performs this monthly recalculation automatically, which is why the Box 12 Code C figure on your W-2 may not exactly match a simple full-year estimate.
Group-term life coverage that continues after you retire or leave a job can still generate imputed income, but a key relief can apply: for retired employees, the IRS reduces the Table I cost in certain cases, and coverage provided to a former employee is reported on a W-2 with only the uncollected Social Security and Medicare shown (you may owe those directly). If a former employer keeps paying for life coverage above $50,000, expect a year-end W-2 reflecting the imputed value even with no wages. Retirees should confirm whether their plan qualifies for the reduced-cost treatment, as it can substantially lower the taxable amount at the older ages where Table I rates are highest.
It is the taxable value of employer-paid life insurance coverage above $50,000. The first $50,000 is tax-free, but the cost of the excess — priced by IRS Uniform Premium Table I based on your age — is added to your W-2 wages and taxed, even though you receive no cash.
Subtract $50,000 from total coverage to get the excess, divide by 1,000 for units, multiply by the IRS Table I monthly rate for your age, then by months covered. For $150,000 coverage at age 46: 100 units x $0.15 x 12 = $180 of annual imputed income.
No. Only the IRS Table I cost of the coverage above $50,000 is taxed, not the coverage itself. A $150,000 policy at age 46 produces only about $180 of imputed income for the year, not $150,000 or $100,000.
It is included in Boxes 1, 3, and 5 (federal, Social Security, and Medicare wages) and listed separately in Box 12 with code C. It is collected through normal payroll withholding, so there is no separate bill.
IRS Table I rates rise with age because insuring an older life is more expensive. The same excess coverage costs $0.08 per $1,000 monthly at age 30 but $1.27 at age 66, so older employees with large policies see far more imputed income.
Yes, by declining coverage above $50,000 if your plan allows, paying for the excess with after-tax dollars (which offsets the imputed amount), or buying a personally owned term-life policy instead, which creates no imputed income.
Yes, dollar-for-dollar. If your Table I cost is $180 and you pay $120 after-tax through payroll, only $60 is imputed. Pre-tax cafeteria-plan contributions, however, do not reduce imputed income.
