What Group Life Insurance Covers — and What It Doesn't
Group life insurance is term life cover provided through your employer. The first $50,000 of basic group cover is tax-free under IRC §79 — the IRS does not impute income on the premium. Cover above $50,000 generates "imputed income" that appears on your W-2 and is taxed at ordinary income rates, though the cost is still typically far below individual term-life premiums. Most employers provide 1-2× annual salary at no cost; some allow you to buy supplemental cover at group rates (3-5× salary, up to a cap of $500K-$1M).
The fatal flaw in relying on group cover alone: it ends when your job ends. According to the U.S. Bureau of Labor Statistics, the median tenure with a single employer is 4.1 years — meaning most workers will lose their group cover multiple times during the years they have dependents. Group cover is also rarely portable; a few plans offer "conversion" to permanent coverage at significantly higher rates, but most simply terminate. Use group cover as a free baseline and supplement with individual term life that you own personally.
The DIME Method — Sizing Your Real Life-Insurance Need
The DIME method (Debt, Income, Mortgage, Education) provides a structured way to estimate the death benefit your family actually needs. Debt: pay off all non-mortgage debt so the surviving spouse isn't stuck with auto loans and credit cards. Income: 10-15 years of replacement income (longer if children are young). Mortgage: full mortgage payoff so the family stays housed. Education: project college costs at $40,000-$60,000 per year per child for 4-year degrees. Subtract existing savings, retirement assets, and other life insurance from this total to find the gap.
An alternative is the 10× income rule — multiply annual income by 10. This is a quick sanity check but ignores debts and family-specific needs. DIME is more accurate but requires inputs. For a comparison of permanent vs term, see our term vs whole life comparison. For broader cover sizing, the term life needs calculator uses the same DIME framework but focuses on individual policy cover rather than group cover gap.
Tax Treatment of Group Life — The $50,000 Trap
Section 79 of the Internal Revenue Code makes the first $50,000 of employer-provided group term life insurance tax-free. Above $50,000, the IRS uses Table I (an age-based premium table) to calculate "imputed income" — a phantom income added to your taxable wages on Form W-2 box 12 code C. For most employees, this adds $5-$50/month to taxable wages, depending on age and cover amount. The cost is still much lower than buying equivalent individual term life, especially for older or less-healthy workers, but it does reduce the tax-free benefit attractiveness.
When to Decline Optional Supplemental Group Cover
If you're young and in good health, individually-purchased term life insurance is usually cheaper than employer supplemental cover, and it stays with you when you change jobs. Supplemental group cover is the right choice when: you have a serious health condition (you may not qualify individually), you smoke, or you're 50+ (group rates flatten across age more than individual rates). Run quotes both ways before defaulting to the employer option.
