Delaware Domestic Insurers' Privilege Tax is a tax imposed on the gross premiums written by domestic insurance companies doing business in the state of Delaware. Domiciled insurers are subject to the tax on their written premiums for all business written in Delaware, regardless of where the policyholder resides. The Delaware Domestic Insurers' Privilege Tax is divided into two categories: property and casualty insurance and life and health insurance. Property and casualty insurance companies are subject to a tax of 4.9% on written premiums, while life and health insurance companies are subject to a tax of 5.8% on written premiums. The tax is due quarterly and must be paid by the 25th day of the month following the end of the quarter. Failure to pay the tax by the due date will result in a penalty of 5% of the tax plus interest. The tax is administered by the Delaware Division of Revenue and all taxes must be paid electronically. Insurance companies must file an annual privilege tax return detailing the gross premiums written for the year.
