The disposable tax return preparation device is adapted to prepare an electronic tax return based on the tax related data. A communications cable is also provided for communicatively coupling the disposable tax return preparation device to a telecommunications system, for transmitting the electronic tax return to a remote tax return preparation system also coupled to the telecommunications system. The remote tax return preparation system is adapted to receive the tax return prepared by the disposable tax return preparation device, confirm the tax return, and electronically file the tax return with a tax authority.
