What Does SDI Stand for in Taxes? Rates, States, and Deductions

On a pay stub or W-2, SDI stands for State Disability Insurance: a mandatory payroll deduction in a handful of states that funds short-term wage replacement when a non-work-related illness, injury, or pregnancy keeps you off the job. The withholding is small, usually between 0.5% and 1.3% of wages, and at tax time it can be deductible on your federal return — but only if you itemize.

What the SDI Deduction Actually Pays For

SDI is a state-run insurance program funded through payroll. When you can’t work because of a qualifying medical condition, the state pays you a portion of your regular wages while you recover. Covered conditions include surgery recovery, serious illness, pregnancy and childbirth complications, and mental health conditions that make work impossible. Most state SDI funds also pay Paid Family Leave benefits, which cover time off to bond with a new child or care for a seriously ill family member.1Employment Development Department.

The work-related distinction matters. Injuries that happen on the job are handled by workers’ compensation, which is a separate employer-funded system. SDI applies only to conditions that arise outside of work. It also differs from unemployment insurance, which requires you to be able to work and actively job-hunting.2Employment Development Department. Unemployment Eligibility Requirements SDI covers the opposite: you have a job, but your body won’t let you do it.

How SDI Appears on Your Pay Stub and W-2

On a pay stub, look for abbreviations like CA SDI, NJ TDB, NY DBL, HI TDI, or RI TDI. The label depends on your state and your employer’s payroll system, but they all describe the same type of mandatory disability contribution. TDI stands for Temporary Disability Insurance and DBL for Disability Benefits Law; the three initials all point to the same kind of program.

On your W-2, the amount withheld during the year is reported in Box 14. Box 14 is a catch-all space for informational items, and employers can label it however they want.3Internal Revenue Service. Form W-2 Wage and Tax Statement 2026 You might see CASDI, SDI, NJ TDI, or a similar entry. That dollar figure is what you’ll need if you plan to deduct the contribution on Schedule A.

Which States Actually Collect SDI

Five states and one territory run traditional SDI programs: California, Hawaii, New Jersey, New York, Rhode Island, and Puerto Rico.4Department of Labor. Temporary Disability Insurance If your pay stub shows an SDI, TDI, or DBL line, you almost certainly work in one of them.

Washington, Massachusetts, Colorado, Connecticut, Oregon, and several other states have enacted Paid Family and Medical Leave programs that overlap with SDI in function. Those are structured differently, often with shared employer-employee contributions, and they generally don’t use the SDI label on pay stubs. If you’re in one of those states, the line item on your stub will carry a different name.

How Much Comes Out of Your Paycheck

SDI is withheld as a percentage of your gross wages. Rates and wage bases vary widely across the five states:

The spread is large. A California worker earning $150,000 pays $1,950 a year in SDI, while a New York worker at the same salary pays about $31. Where you work shapes the cost far more than how much you earn.

Can You Deduct SDI on Your Federal Return?

Yes, but only if you itemize. The IRS treats mandatory contributions to qualifying state disability funds the same way it treats state income taxes: they go on Schedule A as part of the State and Local Tax deduction.10Internal Revenue Service. Topic No. 503, Deductible Taxes The Schedule A instructions specifically list the nonoccupational disability funds of California, New Jersey, and New York, the Rhode Island Temporary Disability Benefit Fund, and the Washington State Supplemental Workmen’s Compensation Fund as qualifying.11Internal Revenue Service. Instructions for Schedule A Form 1040

The practical catch is the SALT cap. Your combined deduction for state income taxes, sales taxes, property taxes, and mandatory disability contributions is limited to $40,000 per year ($20,000 for married filing separately). The cap phases down for higher earners: once modified adjusted gross income exceeds roughly $500,000 ($250,000 for married filing separately), the ceiling drops, though never below $10,000.10Internal Revenue Service. Topic No. 503, Deductible Taxes These thresholds adjust for inflation.

If you take the standard deduction, which most filers do, your SDI withholdings give you no federal tax benefit. There’s no above-the-line deduction on Form 1040 for SDI. For the deduction to help, your total itemized deductions have to exceed the standard deduction, and your SALT items collectively need to be large enough to matter within the cap. This is where the confusion usually starts: the contribution is technically deductible, but through a route most taxpayers don’t take.

Are the Benefits You Receive Taxable?

The tax treatment of SDI benefits depends almost entirely on who paid for the coverage. The IRS rule: if you paid the premiums, the benefits are not taxable; if your employer paid, the benefits are taxable.12Internal Revenue Service. Publication 525, Taxable and Nontaxable Income

In California and Rhode Island, employees fund 100% of the SDI program. Disability benefits from those states are generally not taxable on your federal return, though Paid Family Leave treatment can differ. In New Jersey and Hawaii, employers contribute part of the cost, so some or all of the benefits can be taxable. New York requires employers to provide coverage, often through private insurers, and the employer usually bears most of the cost, so benefits there are commonly taxable.4Department of Labor. Temporary Disability Insurance

If your benefits are taxable, you’ll receive a Form 1099-G from the state agency or private insurer showing the total paid during the calendar year.13Employment Development Department. Tax Information Form 1099G Report that figure as income on your federal return. If the benefits aren’t taxable, you may still get the form but won’t owe federal tax on the payments. State tax treatment can differ from the federal rules, so check your state’s income tax instructions before filing.

A note on private employer plans: California, New Jersey, New York, Hawaii, and Puerto Rico all allow employers to substitute an approved private plan for the state program. If your employer funds that private plan rather than deducting the premium from your pay, benefits are generally taxable for federal purposes.12Internal Revenue Service. Publication 525, Taxable and Nontaxable Income Check your paycheck. If an employee deduction for the disability plan appears and you’re funding the full cost, your tax position is generally the same as someone on the state plan.

If You’re Self-Employed and Don’t See SDI on a Paycheck

Self-employed workers don’t have SDI withheld because there’s no employer running payroll. California offers a Disability Insurance Elective Coverage program that lets you opt in and get the same disability and paid family leave coverage a regular employee has.14Employment Development Department. Disability Insurance Elective Coverage FAQs

The cost is higher than the employee rate. For 2026, the elective coverage premium is 8.84% of the net profit reported on your 2024 Schedule SE. If your net profit was $4,600 or less, you pay a flat annual premium of $406.64 in quarterly installments.15Employment Development Department. Disability Insurance Elective Coverage Rate Notice and Instructions for Calculating Annual Premiums There’s a six-month waiting period after enrollment before you can file a claim, and your profits need to stay at $4,600 or above; three consecutive years below that threshold can trigger cancellation.14Employment Development Department.
