Years of pre-tax savings one claim would cost
59.7
pre-tax saves $59 a year; a 12 months claim then costs $3,517 in tax
| Premium paid after tax, a year | $300 |
| Same premium paid pre-tax, real cost | $241 |
| Your marginal federal rate | 12% |
| Benefits over the claim | $36,000 |
| Tax on them if the premium was pre-tax | $3,517 |
After-tax premiums make the benefit tax-free (IRS Pub. 525). The tax on a claim assumes no other income that year; with other income it is higher.

Paying a disability premium by pre-tax payroll deduction saves income tax and payroll tax on the premium every year, and makes every dollar of a future benefit taxable. Paying it after tax costs a little more each year and makes the benefit tax-free (IRS Publication 525). The saving is a percentage of the premium; the tax is a percentage of the benefit. A single filer earning $70,000 who pays $360 a year saves about $107 a year by paying pre-tax, at a 22% marginal rate plus payroll tax. A one-year claim of $3,500 a month would then cost about $4,467 in federal income and payroll tax, the savings of 42 years. A five-year claim would cost $40,741. The pre-tax option wins only if you never claim, and disability is precisely the risk the policy is bought for.
What each election does
A pre-tax deduction takes the premium out of your pay before federal income tax and, under a cafeteria plan, before Social Security and Medicare. Your taxable wages fall by the premium, and the tax on them falls by the premium times your marginal rate plus 7.65% of payroll tax below the wage base. In exchange, the IRS considers that the employer paid the premium: Publication 525 says that when the premium of a plan under a cafeteria plan was not included in your income, you are not considered to have paid it and the benefits are income. Publication 15-A adds that such pre-tax contributions are employer contributions, so the benefit is also sick pay subject to payroll tax in its first months.
An after-tax deduction leaves your taxable wages unchanged. The premium costs you its full amount, and the benefit is not income. Nothing else differs: same insurer, same formula, same maximum.
The arithmetic of the choice
The calculator above computes both sides. The yearly saving is the premium times your marginal federal rate for 2026 (Revenue Procedure 2025-32) plus payroll tax. The cost of a claim is the federal income tax on the benefits received, assumed to be your only income that year, plus Social Security and Medicare for the first six months. Dividing one by the other gives the number of years of saving that one claim of the length you enter would erase.
The result is rarely close. In the example of the summary, the ratio is 42 years for a one-year claim. The reason is structural: the premium for group disability coverage is a small fraction of the benefit it buys, so a tax rate on the premium can never match a similar tax rate on the benefit unless the probability of a claim is very small. The calculator assumes no other income in the claim year; a claim that starts late in the year, on top of most of a year of wages, is taxed at a higher rate and makes the pre-tax option worse.

When pre-tax can still make sense
Short-term disability with a low benefit and a short duration is the closest case: a claim lasts weeks, not years, and the tax on it is small. Someone who already holds an individual tax-free policy covering most of the risk may also accept a taxable group benefit on top. In both cases, enter the benefit and the length of claim you think plausible, and read the ratio.
Imputed income and gross-up
Some employers pay the premium and add it to your taxable wages, a practice known as imputed income. Others give a choice at enrollment. Either way the effect is the same as paying after tax: you are taxed on a small premium every year, and the benefit, if it comes, is tax-free. For a plan whose cost is shared, the benefit is taxable in the employer's share of the premium over the three previous policy years; the tax calculator applies that share.
Where to find the election
The benefits enrollment portal shows the premium per pay period and, when there is a choice, how the premium is taxed. The pay slip confirms it: a disability line listed with the pre-tax deductions means a taxable benefit. The summary plan description of the long-term or short-term plan gives the benefit to enter.
