Group-term life imputed income calculator

What this calculator tells you

Group-term life insurance from your employer is tax-free up to $50,000 of coverage. Above that, the IRS treats the cost of the extra coverage as part of your pay. This “imputed income” is added to your taxable wages even though you never receive it as cash. The calculator above works out that amount using the official IRS rate table, so you can check the GTL line on your paystub or decide whether a large employer benefit is worth its tax cost.

The IRS explains that a taxable fringe benefit arises if coverage exceeds $50,000, and that the imputed cost is subject to Social Security and Medicare taxes.

How the imputed income formula works

The IRS method in Publication 15-B has four steps:

1. Subtract $50,000 from your total employer-provided group-term coverage.
2. Round to the nearest $100 and divide by 1,000 to get “thousands of coverage”.
3. Multiply by the Table 2-2 rate for your age band and by the number of months you were covered.
4. Subtract anything you paid toward the coverage with after-tax money.

Written out:

Imputed income = (Coverage − $50,000) ÷ 1,000 × monthly rate × months − amount you paid

Worked example: the IRS’s own case

The calculator opens with the example the IRS uses in Publication 15-B. Tom is 45. His employer provides $200,000 of group-term life coverage, and Tom pays $100 a year toward it.

The IRS confirms that Tom’s employer must include $170 in his wages. Payroll tax on that amount at 7.65% is about $13, and income tax depends on Tom’s own bracket. That is the whole cost of Tom’s large employer benefit: modest, but not zero.

A second example at a higher age

Say Rosa is 58 and her employer provides three times her $90,000 salary, $270,000 of coverage, at no cost to her. The excess is $220,000, or 220 thousands. At the 55 to 59 rate of $0.43, the yearly imputed income is 220 × $0.43 × 12 = $1,135.20. The same benefit costs Rosa far more in tax than it would a 35-year-old, which is why the age band matters.

What the result means for you

A few things to keep in mind when you read the result:

• It is not a bill. Imputed income raises your taxable wages. The actual tax is the Social Security and Medicare tax (7.65% for most employees) plus income tax at your marginal rate.
• It shows on your W-2. The IRS says the amount is included in boxes 1, 3 and 5 and reported in box 12 with code C.
• It changes with age and salary. If your coverage is a multiple of salary, both a raise and a birthday into a new age band can increase it.
• It is usually cheap protection. Even with the tax, employer group-term life is often less expensive than buying the same coverage yourself. The bigger question is whether the coverage will last; see our guide on whether life insurance through work is enough.

Rules that can change the answer

• Key employees. If a plan favors key employees, those employees may have to include the full cost of their coverage, not just the cost above $50,000.
• Dependent coverage. Employer-paid coverage on a spouse or child is generally excludable if the face amount is $2,000 or less; larger amounts follow different rules.
• Former employees and retirees. Coverage above $50,000 provided after you leave can still create imputed income, and you may owe the employee share of payroll taxes with your return.
• Partial years. If you joined or left mid-year, enter only the months you were covered.

Common mistakes

Is the coverage itself enough?

The tax is usually small. The bigger risk is relying on group cover that ends when the job does. Use the life insurance calculator to see your full need, and the term life length calculator to choose how long an individual policy should last.
