State Disability Insurance (SDI) costs vary depending on the state and individual circumstances. In California, for example, the SDI tax rate for employees is 1.2% of the first $128,298 in wages, which means the maximum annual contribution is $1,539.58. Employers also contribute to SDI, but the rate and maximum contribution may differ. In New York, the employee contribution rate for Disability Benefits Law (DBL) coverage is 0.5% of an employee's weekly wage, up to a maximum of $0.60 per week. Employers may deduct up to 0.5% of an employee's weekly wage, up to a maximum of $0.60 per week, to cover the cost of DBL coverage. It's important to note that these rates and limits are subject to change, so it's advisable to check with the specific state's labor department or relevant authority for the most up-to-date information. Additionally, self-employed individuals may also have the option to voluntarily participate in SDI programs, with contribution rates and coverage details varying by state. The cost of State Disability Insurance is influenced by state-specific regulations, individual income, and employment status.
