What it means
The word "term" is the important part. This is insurance that pays only if the covered person dies while the policy is in force, and it accumulates nothing if they do not, which is exactly why it is so cheap per dollar of protection.
For an employer, group term life is the workhorse of the benefits package. One master contract covers everyone in an eligible class, cover is expressed as a formula such as two times salary, and the premium is billed monthly as a rate per $1,000 of aggregate cover.
The nuance that catches payroll teams out is the tax treatment of employer-paid cover. Under United States rules, the first $50,000 of employer-provided group term life is tax free to the employee, and the value of anything above that must be added to taxable wages using a published age-banded rate table.
That added amount is called imputed income. It is not cash the employee receives; it is a notional value on which they pay tax, and it appears on the payroll record alongside real earnings, which is why employees often query it.
Any after-tax contribution the employee makes towards the cover reduces the imputed income dollar for dollar. Voluntary supplemental cover bought entirely with the employee's own after-tax money therefore creates no imputed income at all.
In practice
Real-world examples.
Example
A 300-person engineering firm provides group term life at three times salary. Payroll runs an annual calculation each December to add imputed income for the roughly 90 employees whose cover exceeds $50,000, then reports it on their year-end wage statements.
Example
A retail group offers $50,000 of employer-paid cover to every employee and lets staff buy supplemental cover in $25,000 units through after-tax payroll deductions. Because the employer-paid portion stops exactly at the threshold, no imputed income arises for anyone.
Example
A newly promoted director sees an unfamiliar $34 line on her payslip and raises it with HR. It turns out to be monthly imputed income on $500,000 of employer-paid cover, and HR explains that the cover itself is free to her while only the notional value above $50,000 is taxed.
Formula
Calculation
Annual imputed income = ((cover - $50,000) / $1,000) x monthly rate for the employee's age band x 12, less any after-tax employee contributions
An employee aged 45 has employer-paid group term life cover of $200,000. Suppose the applicable published monthly rate for that age band is $0.15 per $1,000 of cover.
Cover above the exempt threshold = $200,000 - $50,000 = $150,000
Number of $1,000 units = $150,000 / $1,000 = 150
Monthly imputed value = 150 x $0.15 = $22.50
Annual imputed value = $22.50 x 12 = $270
If the employee pays nothing towards the cover, $270 is added to taxable wages for the year. If instead the employee contributes $5 a month after tax, that is $60 a year, and the reportable imputed income falls to $270 - $60 = $210.
At a 24% marginal tax rate, $210 of imputed income costs the employee about $50 in tax for the year, against $200,000 of protection.Case study
Seen in the real world.
The following is an illustrative and fictional scenario. Alderwood Systems raised its group term life cover from one times salary to three times salary as part of a benefits refresh, moving most of its 220 employees well above the $50,000 exempt threshold for the first time. The insurance cost rose by a manageable amount, but nobody told payroll.
At year end the auditors flagged that imputed income had never been calculated. Alderwood had to recalculate the value for every affected employee, restate the year's wage reports, and explain to staff why a benefit they had been told was free had produced a small additional tax charge. For a 45-year-old on $200,000 of cover the amount was only $270 for the year, but the surprise did more damage than the sum.
The illustrative lesson is procedural rather than financial. Any change to group term life cover levels needs a corresponding change to the payroll calculation, and the communication to employees should mention imputed income before the first payslip shows it.
Watch out
Common mistakes.
- Assuming employer-paid life cover is entirely tax free, when in the United States only the first $50,000 escapes imputed income.
- Confusing imputed income with a deduction, and telling employees that money has been taken from their pay when only their taxable wage figure has increased.
- Expecting group term life to build up value like a savings product, when it pays only on death during the covered period.
Questions
People also ask.
How is imputed income calculated?
Take cover above $50,000, divide by $1,000, multiply by the published monthly rate for the employee's age band, then multiply by the number of months of cover.
Do employee after-tax contributions reduce the taxable amount?
Yes, contributions paid with after-tax money are subtracted directly from the imputed value, and can reduce it to zero.
What happens to the cover when someone leaves?
It normally ends on the final day of employment, though most master policies allow conversion to an individual policy within a short window without medical evidence.
