FMLA vs Short-Term Disability: The Difference in 2026

What is the difference between FMLA and short-term disability?

FMLA and short-term disability solve different problems and usually run at the same time. The FMLA is a federal law that protects your job and your health insurance for up to 12 workweeks a year while you are out for a serious health condition, but it pays nothing. Short-term disability (STD) is an insurance benefit, provided by your employer or bought individually, that replaces part of your income, typically 50 to 70 percent of base pay, after a waiting period of about 7 days, for a limited period, commonly 3 to 6 months. STD does not protect your job; FMLA does not pay. When a condition qualifies under both, the employer designates FMLA at the start of the disability claim so the two run concurrently: the insurer pays while the FMLA clock holds the position. Five states, California, Hawaii, New Jersey, New York, and Rhode Island, require employers to provide disability coverage; elsewhere it is a voluntary benefit. Source: 29 CFR Part 825 and individual plan documents.

What does FMLA do that short-term disability does not?

FMLA is a legal guarantee, and its three promises have no equivalent in an insurance policy. The first is restoration: when the leave ends, you return to the same position or one with equivalent pay, benefits, shift, and location, and the employer cannot fill the role permanently while you are out. The second is health insurance: the employer must keep your group coverage running on the same terms, paying its share as if you were at work. The third is protection from retaliation: the absence cannot be counted under an attendance policy or used against you in a promotion or layoff decision, and interfering with the leave is unlawful.

FMLA also covers ground that disability insurance never touches. A disability plan pays only when you are the patient. FMLA protects leave to care for a spouse, child, or parent with a serious health condition, to bond with a new child, and for military family needs, none of which involve your own incapacity. A father taking eight weeks with a newborn is on FMLA leave with no disability claim at all; a daughter caring for a parent after a stroke is in the same position. For those leaves the pay layer, if there is one, comes from a state paid family leave program or a company policy, not from STD.

What does short-term disability do that FMLA does not?

It pays. That single fact makes STD the more valuable of the two for most people during a medical leave, because the FMLA's protections are worth little if you cannot cover rent for eight weeks. A typical group plan replaces 60 percent of base salary, some plans 50 or as much as 70, from the eighth day of disability for accidents and illnesses alike, up to a maximum that is often 13 or 26 weeks. Pregnancy is the most common claim: plans commonly pay six weeks for a vaginal delivery and eight for a caesarean, longer with complications.

STD also reaches people the FMLA does not. It has no 50-employee threshold and no 1,250-hour test; a new hire at a 20-person company can be covered from the first day of the plan year if the plan says so. And it can outlast the FMLA: a 26-week plan keeps paying for three months after the 12 weeks of job protection have expired. What it never does is hold the job. The plan document is silent on your employment; the insurer's only question is whether you meet its definition of disabled, which usually means unable to perform the material duties of your own occupation, and whether the condition is excluded, for example as pre-existing in the first year of coverage.

FMLA vs short-term disability side by side

The comparison is easiest to hold as a table. Read each row as an independent question rather than as a contest; for most medical leaves the correct answer is that both apply.

Can you use FMLA and short-term disability at the same time?

Yes, and for an eligible employee with a qualifying condition the employer is expected to make it happen. Once the employer knows that an absence is for a serious health condition, which a disability claim makes obvious, it must designate the leave as FMLA within five business days and the two run concurrently from the first day. The employee does not get to bank the FMLA for later by saying they would rather use only disability; designation is the employer's duty, not the employee's choice. Running the two together is also what protects the employer, because it means the 12 weeks of job protection and the 26 weeks of benefits start on the same day rather than stacking into eight months of held position.

Take Jonas, a software engineer in Texas earning $1,500 a week at a 300-person company, who needs a knee reconstruction with a certified ten-week recovery. His employer's plan pays 60 percent after a 7-day elimination period. Week one: the plan pays nothing, and Jonas uses five accrued sick days to receive his full $1,500. Weeks two through ten: the plan pays $900 a week. Because he is receiving disability benefits, the employer cannot force him to burn PTO on top, but the two agree that he will use one vacation day a week, adding $300, to take home $1,200 in those weeks. Across the leave he receives $12,300 and uses 5 sick days and 9 vacation days. All ten weeks are FMLA leave, 400 of his 480 hours, so his position is held, his health insurance continues with his share paid monthly, and he returns to the same team on the Monday of week eleven with 80 FMLA hours left for the year.

The one restriction to remember is the substitution rule: while disability or workers' compensation benefits are being paid, the employer may not require the employee to use accrued paid leave, because the leave is already partly paid. Top-ups are allowed only by agreement, as in Jonas's case, and where state law permits.

What happens when short-term disability lasts longer than FMLA?

The FMLA guarantee ends when the 12 workweeks are used, and that date can arrive while the disability plan is still paying. At that point the law changes hands. If the condition is a disability under the Americans with Disabilities Act, which applies at employers with 15 or more employees, additional leave can be a reasonable accommodation the employer must consider unless it causes undue hardship; indefinite leave generally is not. Some states extend job-protected medical leave beyond 12 weeks, and California's pregnancy disability leave, up to four months, runs in addition to bonding leave under CFRA. And many employers hold positions longer under their own leave-of-absence policy, which is worth reading before the twelfth week rather than after.

The reverse also happens. A plan that pays for 13 weeks stops a week after FMLA protection does; a plan that excludes a pre-existing condition may deny the claim entirely while the FMLA leave is fully protected. And at the far end, a disability that outlasts the STD maximum moves to long-term disability insurance, if the employer offers it, typically after 90 or 180 days. None of those transitions change the FMLA clock; they change who is paying and whether the job is still held.

Which states require short-term disability insurance?

Five states and Puerto Rico require employers to provide temporary disability coverage for an employee's own non-work-related illness, injury, or pregnancy: California through State Disability Insurance, Hawaii through Temporary Disability Insurance, New Jersey through Temporary Disability Benefits, New York through the Disability Benefits Law, and Rhode Island through Temporary Disability Insurance. In those states the state program, or an approved private plan that matches it, is the pay layer for most medical leaves, and the percentages and weekly caps are set by statute and updated each year.

The thirteen paid family and medical leave jurisdictions overlap with this list. California, New Jersey, New York, and Rhode Island run their family leave programs alongside the disability programs above; Colorado, Connecticut, Delaware, the District of Columbia, Maine, Massachusetts, Minnesota, Oregon, and Washington cover an employee's own serious health condition inside a single paid leave program, which functions like state-run short-term disability. Everywhere else, STD exists only if the employer offers it or the employee buys it, and roughly two in five private-sector workers have access to it through work, according to the Bureau of Labor Statistics' National Compensation Survey.

How should employers coordinate FMLA and short-term disability?

The operational mistake is treating them as one process. They share a medical event and often a single certification, but they answer to different rules: the FMLA is measured in hours of protection under a 12-month method; STD is measured in dollars and weeks under a plan document, usually by an outside insurer. An employer that lets the insurer's approval stand in for FMLA designation ends up without the designation notice the regulations require, and one that waits for the FMLA paperwork before starting the claim delays the employee's pay.

The clean setup opens both on day one from one intake: the leave case records the FMLA designation, the hours, and the certification; the disability claim runs with the insurer and its payments are noted on the case as the pay source; any PTO top-up is recorded as substitution by agreement. Medical documents stay in the confidential file, separate from the personnel record. When the FMLA hours run out, the case flags the transition so that the ADA and policy questions are asked before the twelfth week, not after. Time-Out Zone models leave cases with the protection clock and the pay sources side by side for exactly this reason.
