Disability benefits are taxable income when your employer paid the premium, and also when you paid it through a pre-tax payroll deduction, because the IRS treats a premium excluded from your wages as paid by the employer. They are tax-free when you paid the premium with after-tax money, including an individual policy you bought yourself (IRS Publication 525). When the cost is shared, only the part of the benefit that matches the employer's share of the premium over the three previous policy years is taxed: in the IRS example, an employer paying 70% makes $1,400 of each $2,000 check taxable. Employer-funded benefits also carry Social Security and Medicare for the first six calendar months after the last month worked. A $3,000 monthly benefit paid all year, employer-funded, adds about $2,140 of federal income tax for a single filer with no other income in 2026, plus $1,377 of payroll tax.
The rule in one sentence
The tax rule for a disability benefit follows the tax rule for the premium. A premium paid with money that was taxed gives a tax-free benefit; a premium that escaped tax, because the employer paid it or because it was deducted before tax, gives a taxable benefit. The rule comes from section 105 of the Internal Revenue Code and is explained in IRS Publication 525, under sickness and injury benefits. It does not depend on the insurer, on the length of the claim or on whether the plan is called short-term or long-term.
The table under the calculator applies the rule to the five arrangements found in practice: an employer-paid group plan, a group plan paid by pre-tax deduction, a group plan paid after tax, a plan whose cost is shared, and an individual policy. Enter your own benefit and income and the tax changes with them; the ranking between arrangements does not.
Pre-tax deductions: the trap
Employees often choose the pre-tax option at enrollment because it lowers the tax on every paycheck, without seeing that it moves the tax to the claim. Publication 525 is explicit about cafeteria plans: if the premium was not included in your income, you are not considered to have paid it, and the benefits are income. Publication 15-A says the same from the employer's side: contributions made with employees' pre-tax dollars under a cafeteria plan are employer contributions. The saving on the premium is small, a percentage of a few hundred dollars a year; the tax on a claim is a percentage of thousands of dollars a month. The election calculator sets one against the other.

Shared premiums and the three-year rule
When both the employer and the employees pay for a group policy, the taxable share of each benefit is the employer's share of the policy's cost over the three policy years before the calendar year of the payment. If the policy is newer, the years in effect are used. The IRS example in Publication 15-A: an employee is paid $2,000 a month for three months under a policy whose cost was paid 70% by the employer and 30% by employees with after-tax money; $1,400 of each payment is taxable sick pay, and the remaining $600 is neither taxable nor subject to employment taxes. Your employer or the insurer applies the percentage; the calculator uses the after-tax share you enter in the options.
Social Security, Medicare and withholding
A taxable benefit from an employer plan is sick pay. Social Security at 6.2% and Medicare at 1.45% apply to it until 6 calendar months have passed after the last month you worked, as in the Publication 15-A example of an employee who stopped work in December 2025 and owes no payroll tax on sick pay paid after June 30, 2026. A day of work during the claim restarts the count. Income tax withholding on sick pay paid by an insurer is usually voluntary, requested on Form W-4S; without it, a long claim can leave a large balance due, and estimated payments may be needed.
What the benefit does to the rest of the return
A taxable benefit is added to your other income for the year, so the tax it adds depends on what else you earned. A claim that starts in the autumn falls on top of most of a year's wages and is taxed at your usual rate; a claim that runs a full year with no wages is taxed from the bottom of the brackets, after the standard deduction of $16,100 for a single filer in 2026 (Revenue Procedure 2025-32). A Social Security disability award brings its own rule: up to 85% of it can be taxable, depending on your other income (Publication 915). The offset page shows how the award reduces the plan check.
State tax
State rules are not computed here. States generally start from federal income, but each one has its own exclusions, and a benefit paid by a state disability program is a separate case.
