Employer-paid long-term disability premiums are not taxable to employees. Under Section 106(a) of the Internal Revenue Code, employer-provided coverage under an accident or health plan is excluded from your gross income, so the premium your employer pays for your LTD policy doesn’t show up as wages on your paycheck and you owe no tax on it.1Office of the Law Revision Counsel. 26 U.S. Code 106 – Contributions by Employer to Accident and Health Plans The catch is what happens later: because no one paid tax on the premium, any disability benefits you eventually collect will be fully taxable as ordinary income.
Why the Premium Is Tax-Free but the Benefit Isn’t
Three sections of the tax code work together here. Section 106(a) excludes employer-provided health and accident coverage from your income.1Office of the Law Revision Counsel. 26 U.S. Code 106 – Contributions by Employer to Accident and Health Plans Section 105(a) then says that benefits paid out of that coverage are included in your gross income to the extent they’re attributable to employer contributions that weren’t taxed when paid.2Office of the Law Revision Counsel. 26 USC 105 – Amounts Received Under Accident and Health Plans Section 104(a)(3) supplies the other side: benefits from accident or health insurance are excluded from income, except to the extent they’re attributable to untaxed employer contributions.3Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness
The plain rule that comes out of all this: if the premium dollars were taxed before they reached the insurer, the benefit is tax-free. If they weren’t, the benefit is taxable. The identity of the payer doesn’t decide it. What decides it is whether the money was taxed on the way in.
What Fully Taxable Benefits Actually Costs
Group LTD policies typically replace about 60% of your pre-disability salary. If you earn $80,000 and become disabled, the policy might pay roughly $4,000 a month. When that benefit is fully taxable, federal and state income tax can eat a quarter or more of it, leaving you closer to 40% to 45% of your former paycheck rather than the 60% the policy nominally promises. Over an extended disability, that gap adds up fast.
This is the real cost of the Section 106(a) exclusion. The premium tax break is small; the benefit tax bill can be enormous. A person earning $75,000 with a $900 annual LTD premium saves only a couple hundred dollars in taxes by having the employer pay it tax-free. But if that person becomes disabled and collects $45,000 a year in taxable benefits, the tax bill on the benefit side can run $7,000 to $9,000 a year, depending on the rest of the return.
The Imputed Income Alternative
Some employers offer a different arrangement. Rather than paying the premium tax-free, they add the premium value to your W-2 as taxable wages, a practice called imputed income. You pay income tax and FICA on that amount now. In exchange, any disability benefits you later receive are entirely tax-free under Section 104(a)(3).3Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness
The current cost is modest. Group LTD premiums typically run 1% to 3% of annual salary. On a $70,000 salary, that’s $700 to $2,100 of extra taxable income per year, adding roughly $150 to $500 in federal tax at a 22% marginal rate. If you want to check whether your employer is doing this, look on your pay stub for a line showing the LTD premium as taxable income. There is no dedicated W-2 box code for it; the amount is simply folded into Boxes 1, 3, and 5.4Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3 Some employers voluntarily break it out in Box 14, but that box is informational and optional.
When You Pay Part or All of the Premium Yourself
If you contribute to the premium through payroll deduction, the tax outcome depends entirely on whether the deduction comes out pre-tax or post-tax.
Post-Tax Deductions
Money withheld from your paycheck after income tax and FICA have already been calculated has already been taxed. You get no current-year deduction for it, but any disability benefits attributable to that portion of the premium are excluded from your gross income.3Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness This is the most reliable way to lock in tax-free benefits.
Pre-Tax Deductions Through a Cafeteria Plan
Some employers route LTD premiums through a Section 125 cafeteria plan, letting you pay with pre-tax salary reduction dollars. Section 125 excludes those amounts from your gross income.5Office of the Law Revision Counsel. 26 U.S. Code 125 – Cafeteria Plans For benefit-taxation purposes, however, the IRS treats those pre-tax employee dollars the same as employer dollars. Your future benefits will be fully taxable, just as if the employer had paid the premium directly.2Office of the Law Revision Counsel. 26 USC 105 – Amounts Received Under Accident and Health Plans
People often pick the pre-tax option at open enrollment because it shaves a few dollars off each paycheck. That small paycheck savings can turn into tens of thousands of dollars of tax on the benefit side if a claim ever happens.
Split-Cost Plans and the Three-Year Allocation
Many group LTD plans split the premium between employer and employee. When you contribute your share with after-tax dollars, benefits are divided proportionally between a taxable piece and a tax-free piece.
The governing regulation, 26 CFR 1.105-1, sets the taxable portion of the benefit equal to the ratio of employer premiums to total premiums over the three most recent policy years.6eCFR. 26 CFR 1.105-1 – Amounts Attributable to Employer Contributions If the employer paid 60% of premiums over that window and you paid 40% with after-tax money, then 60% of each benefit payment is taxable and 40% is tax-free.
The three-year window matters if you’re thinking about switching from pre-tax to after-tax at open enrollment. A recent switch doesn’t fully take effect for tax purposes until three policy years have passed under the new arrangement. That’s another reason to evaluate the election carefully, and early. Switching after you’re already disabled won’t change how those benefits are taxed.
How the Choice Shows Up at Claim Time
Most group LTD benefits are paid by an insurance company, which the IRS calls third-party sick pay. When benefits are taxable, they’re reported to you on Form W-2 (typically for the first six months after you stop working) or on Form W-2 or Form 1099 after that, depending on who administers the plan. Taxable disability payments go on line 1h of Form 1040.7Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income Taxable payments are also subject to the employee share of Social Security tax (6.2% on earnings up to $184,500 in 2026) and Medicare tax (1.45%).8Social Security Administration. Contribution and Benefit Base
When benefits are tax-free because you paid the premium with after-tax dollars, the nontaxable portion appears in Box 12 of Form W-2 with Code J and stays out of Boxes 1, 3, and 5.9Internal Revenue Service. Publication 15-A (2026) – Employer’s Supplemental Tax Guide If a form treats benefits as fully taxable when part should be excluded, Publication 525 advises contacting the payer for a corrected form.7Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income
Changing Your Election
The pre-tax versus after-tax choice is usually made at annual open enrollment. If your LTD premium goes through a Section 125 cafeteria plan, that election is generally locked in for the plan year and can only be changed mid-year for a qualifying life event such as marriage, divorce, birth or adoption of a child, a spouse’s job change, or loss of other coverage.5Office of the Law Revision Counsel. 26 U.S. Code 125 – Cafeteria Plans If the LTD election sits outside a cafeteria plan, the Section 125 irrevocability rules don’t apply, and your employer may allow mid-year changes.
The right time to make this decision is before you need the coverage. The tax treatment of a disability claim is set by how premiums were handled during the years leading up to it, and no election you make after a disability begins will change the taxation of the benefits already flowing from that claim.
