Interest is charged on all overdue (delinquent) taxes. This includes Unemployment Insurance, Employment Training Tax, State Disability Insurance, and Personal Income Tax withholdings.
The interest rate is based on the California Revenue and Taxation Code. The interest rate is adjusted twice a year based on the short-term federal rates in January and July. The California Unemployment Insurance Code does not allow us to waive or cancel interest.
Interest is compounded daily on:
- All unpaid tax.
- Certain penalties.
