Why Worksheet 5‑1 Matters for Your Tax Return
Worksheet 5‑1 is the IRS's shortcut for turning the premium you pay for group term life insurance into a dollar amount that must be reported as taxable income. The calculation hinges on the value of the coverage you receive, the cost of the coverage per $1,000 of benefit, and the applicable federal rates for the year. Getting the worksheet right avoids under‑reporting income and prevents costly amendments later.

Key Variables You'll Need
Before you start, gather these pieces of information:
- Annual premium paid by your employer for the group term life policy.
- Amount of coverage provided to you (the benefit limit).
- IRS cost‑of‑coverage tables for the year (usually published in Publication 15‑B).
- Your age as of the first day of the tax year.
These inputs feed directly into the three main sections of the worksheet.
Step‑by‑Step Walkthrough
1. Determine the "cost of coverage" per $1,000
Locate the appropriate row in the IRS table based on your age. For example, a 38‑year‑old in 2024 faces a cost of $0.18 per $1,000 of coverage. This figure is the "cost of coverage" used throughout the worksheet.
2. Calculate the taxable portion of the premium
Use the formula:
Taxable Cost = (Coverage Limit – $50,000) ÷ 1,000 × Cost‑of‑Coverage
If your policy provides $150,000 of coverage, the excess over the $50,000 tax‑free threshold is $100,000. Divide by 1,000 (giving 100) and multiply by $0.18, resulting in a taxable cost of $18.
3. Enter the result on Worksheet 5‑1
Line 1 of the worksheet asks for the "Cost of coverage" you just computed. Transfer $18 to that line. If your employer also pays a portion of the premium that exceeds the $50,000 threshold, add that amount to the figure on line 2.
Example Completed Worksheet
The table below shows a fully populated Worksheet 5‑1 for a typical employee.
| Line | Description | Amount |
|---|---|---|
| 1 | Cost of coverage (excess over $50,000) | $18 |
| 2 | Employer‑paid premium attributable to excess coverage | $0 (if none) |
| 3 | Total taxable cost to include in wages | $18 |
The $18 is added to Box 1 of your Form W‑2 as ordinary wages.
Common Mistakes and How to Avoid Them
- Using the wrong age bracket. The cost‑of‑coverage table changes annually; double‑check the year on the worksheet.
- Forgetting the $50,000 exemption. Only the amount above $50,000 is taxable; many filers mistakenly tax the entire premium.
- Misreading the table units. The IRS lists rates per $1,000 of coverage; do not treat them as per $100 or per $10,000.
- Omitting employer contributions. If the employer pays part of the premium, that portion is also taxable when it exceeds the exemption.
When to Seek Professional Help
If your policy includes multiple tiers of coverage (e.g., supplemental coverage for dependents) or if you receive a cash‑value component, the worksheet alone may not capture the full tax impact. A CPA can reconcile the worksheet with Schedule 1 (Form 1040) and ensure that any additional taxable benefits are reported correctly.
Quick Reference Checklist
- Confirm the tax year's cost‑of‑coverage table.
- Identify your exact coverage amount.
- Subtract the $50,000 tax‑free limit.
- Apply the per‑$1,000 rate to the excess.
- Enter the result on Worksheet 5‑1 and add it to wages.
