State Disability Insurance: Four Mandatory Programs, Four Different Systems

When payroll teams think about state-mandated insurance programs, they often think of them as a single category. In reality, the states that require short-term disability insurance have created five fundamentally different systems—each with its own logic, its own administration, and its own compliance requirements. Understanding the differences isn’t just an academic exercise; it directly affects how employers calculate withholding, submit payments, and administer leave for their employees.

Why These Programs Exist

State disability insurance (SDI) programs provide partial wage replacement to employees who are temporarily unable to work due to a non-work-related illness, injury, or pregnancy. Unlike workers’ compensation (which covers work-related injuries) or state unemployment insurance (which covers job loss), SDI covers the gap when someone is simply sick or recovering.

Five states—California, New Jersey, New York, Rhode Island, and Hawaii—have mandatory SDI programs. Washington State and several other states have added paid family and medical leave programs that overlap with disability concepts, which we’ll cover separately. But the five core SDI states each have distinct programs that payroll professionals in those states must know in detail.

California: SDI

California’s State Disability Insurance is administered by the Employment Development Department (EDD) and is perhaps the most well-known of the state SDI programs.

Rate and wage base: California SDI is funded entirely through employee contributions. In 2024, the employee contribution rate was 0.9% on all wages up to the SDI taxable wage limit (which changes annually). Importantly, California removed its wage cap for SDI effective January 1, 2024—meaning the tax now applies to all wages, not just wages up to a cap. This was a significant change for high earners in California.

Benefits: California SDI pays up to 60-70% of the employee’s weekly wages (the percentage depends on income level), up to a weekly maximum that adjusts annually.

Paid Family Leave: California PFL is administered alongside SDI through the same EDD system and funded by the same employee contribution. This means employers are administering one program that covers both disability and family leave.

Employer administration: California employers generally administer California SDI through the EDD’s payroll tax system, which they’re already using for SUI contributions. This relative integration is one of California SDI’s advantages compared to other states.

New Jersey: Temporary Disability Insurance (TDI)

New Jersey’s TDI is unique in that it requires both employer and employee contributions, and it offers two paths: participation in the state plan or establishment of an approved private plan.

Rate and wage base: Both employers and employees contribute. Rates and wage bases change annually. In recent years, employer rates have been on the order of 0.5% and employee rates around 0.14%, applied to wages up to the annual maximum.

State plan vs. private plan: Employers can either participate in the state TDI fund (administered by the NJ Department of Labor) or establish a private disability insurance plan that meets or exceeds state benefit levels. Large employers sometimes prefer private plans for cost or administrative reasons. Private plans must be approved by the state and audited periodically.

Integration with PFML: New Jersey also has a Family Leave Insurance (FLI) program—funded separately from TDI—that provides paid leave for bonding with a new child or caring for a sick family member.

New York: Disability Benefits Law (DBL)

New York’s DBL (Disability Benefits Law) is employer-administered and employer-funded, with employees contributing a nominal amount.

Rate and wage base: Employees contribute 0.5% of wages up to a weekly maximum of $0.60/week (a cap that hasn’t changed in years). The effective employee contribution is tiny. Employers bear the substantial cost, either through a state plan or by obtaining private insurance.

Private insurance requirement: Unlike California, New York requires employers to obtain DBL coverage from a state-authorized carrier—not from the state itself. This means New York employers must procure and maintain an insurance policy, receive certificates of coverage, and coordinate claims with their carrier. This is fundamentally different from California’s direct employer-to-state model.

New York Paid Family Leave (PFL): New York PFL operates separately from DBL and is funded by employee contributions alone. The two programs (DBL and PFL) are usually packaged together by carriers, but they have different benefit structures, waiting periods, and duration limits.

Coordination of benefits: When an employee takes leave in New York that might qualify under both DBL and PFL (for example, pregnancy), payroll teams must understand how the two programs coordinate—what runs first, what runs concurrently, and what the maximum combined benefit is.

Rhode Island: Temporary Disability Insurance (TDI)

Rhode Island’s TDI is administered by the Rhode Island Department of Labor and Training and is funded entirely by employee contributions.

Rate and wage base: Rhode Island updates its employee contribution rate and taxable wage base annually. Recent rates have been in the range of 1.1% on wages up to a maximum taxable wage base.

Temporary Caregiver Insurance (TCI): Rhode Island also administers TCI—a paid family leave program—through the same withholding mechanism as TDI. Employers withhold a combined TDI/TCI rate and remit to the state.

Employer administration: Employers in Rhode Island withhold the combined TDI/TCI contribution from employee wages and remit to the state quarterly (or more frequently for larger employers). There’s no employer contribution for TDI itself, though employers may offer supplemental plans on top of the state benefit.

Hawaii: Temporary Disability Insurance (TDI)

Hawaii’s program is the least well-known of the five, partly because Hawaii’s relatively small workforce means it affects fewer national employers.

Rate and wage base: Hawaii TDI is funded by both employer and employee contributions. Employee contributions are capped at 0.5% of wages up to a maximum that adjusts each year. Employer contributions cover the remainder of the cost.

Approved plan requirement: Similar to New Jersey, Hawaii employers may satisfy the TDI requirement either through the state plan or through a private plan that meets or exceeds state minimums. Many larger Hawaii employers use private plans.

Claim administration: Unlike California where employees file claims directly with EDD, Hawaii employers may be more involved in coordinating TDI claims—particularly those using private plans.

The Administrative Challenge

Managing SDI obligations across these five states requires maintaining separate systems for:

• Employee contribution rate withholding (each state has its own rate)
• Employer contributions where applicable (New Jersey, Hawaii)
• Reporting and remittance to the correct agency
• Annual rate updates
• Coordination with private carriers (New York, New Jersey, Hawaii)

For a company with employees in all five SDI states, this is five separate administrative tracks running simultaneously—each with different rules, agencies, and deadlines. It’s a non-trivial compliance burden that often falls to the intersection of payroll, HR, and benefits teams, creating coordination challenges when the right information isn’t shared across functions.

Understanding these programs in detail is essential for any payroll operation covering these states—and with expanding remote workforces, many more companies are encountering them than ever before.
