What Is STD on Your Paystub? Short-Term Disability Explained
STD is the premium for short-term disability cover, the benefit that bridges the first weeks out of work. How it pays, how it differs from state disability and the tax consequence.
STD on a pay stub is the premium for short-term disability insurance. It covers the stretch that catches most households out: the first weeks or months away from work, before long-term coverage begins.
How the Benefit Works
After a short waiting period, often a week or two, short-term disability pays a percentage of your base pay for a defined maximum duration, commonly measured in weeks up to a few months. Replacement rates typically sit between 50% and 70%. When the maximum duration ends, long-term disability takes over if the condition continues and the policy qualifies.
Common claims are not exotic. Surgery recovery, serious injury, complications from pregnancy and extended illness make up most of what these policies actually pay for.
The Same Tax Rule as LTD
Who pays the premium determines whether the benefit is taxed. Employer-paid premiums generally produce taxable benefits; premiums you pay with after-tax dollars generally produce tax-free benefits. Where your employer offers the choice, paying post-tax is often the better trade, because a disability benefit has to cover living costs and losing a share of it to tax hurts precisely when it matters.
How It Relates to State Disability
A handful of states run mandatory disability insurance programmes funded by employee contributions, which appear on a stub as SDI rather than STD. If you work in one of those states you may see both lines: a state programme and an employer-sponsored policy that supplements it. They are separate schemes with separate rules.

Check the Definition and the Base
Two details decide how useful the cover is: how the policy defines disability, and what counts as covered earnings. If a large part of your income is commission or bonus and the policy covers base pay only, the real replacement rate is lower than the headline percentage suggests.
