Inheritance tax when due is paid by the Estate of deceased. An Estate tax return Form 706 is the form used to declare the value of the estate and figure the inheritance tax.
Estate/Inheritance tax is due for deaths in 2012 for estates greater than $5,120,000. In your case the total value of the estate is $2,000,000 thus no Federal estate taxes will be paid by the estate. Heirs/beneficiaries of the an estate do not pay any inheritance taxes. They may have to pay income taxes depending on the type of assets inherited.
Generally items that are tax deferred when inherited are subject to income taxes to the heir. These would be pensions, retirement accounts (IRA, 401k, 403b), tax deferred annuities and US Savings bonds. (Roth IRA's are not subject to income tax)
Cash, appreciated property (land, house, farm) are not subject to income taxes to the heirs. This property is valued at the date of death and that value becomes the start point for the heirs. Any income earned on money after death is subject to income taxes on the heirs, ie. interest earned on the CD after death would taxed on the heirs tax return.
Kansas Inheritance tax was repealed for individuals passing after July 1 2008. So no Kansas Inheritance or Estate taxes are due.
So from your description it looks as if you are not inheriting any property that would be subject to income taxes and the value of the estate is under the taxable amount therefore no Estate taxes will be due either.
