Will you have to pay taxes on your inheritance of 900000 in Texas?

As far as Federal income taxes are concerned, inheritance is not taxed on your 1040 return. The Estate itself may be required to file an Estate Tax Return and possibly pay Estate Taxes depending on the total value of the estate in total and the line of inheritance. As far as State taxes in Texas, I am not familiar with that but I doubt very seriously if any income tax is due on a State basis either.
