The California Declaration of Documentary Transfer Tax (CDTF) is a tax imposed by the State of California on the transfer of real property. This includes the sale, exchange, or transfer of any interest in real property, such as a deed, mortgage, lease, option, or other agreement. The tax rate varies by county and is generally based on the sales price of the property. There are two types of California Declaration of Documentary Transfer Tax: Exempt and Non-Exempt. Exempt transfers are those that do not require the payment of tax, while Non-Exempt transfers require the payment of the tax. Exempt transfers include transfers between spouses, transfers related to foreclosure sales, transfers to or from a government entity, and transfers due to the death of an owner. Non-Exempt transfers include transfers of property for consideration, transfers for development, and transfers of property subject to a deed of trust.
