| What are Federal and Ohio Estate Tax Exemptions?
Federal Estate Tax
THE good news is it's unlikely that you'll owe estate taxes based on the facts that you have presented. This is because the Federal Estate Exemption allowance of $2 million in 2006-2008 will exempt any of your parents assets being subjected to Federal Estate Taxes as it does not exceed the exemption amount.
Ohio Estate Tax:
Furthermore, in Ohio State, for dates of death on or after January 1, 2002, an estate tax return (E.T. Form 2) must ONLY be filed for an estate that has a gross value of $338,333 or more regardless of whether a Federal estate tax return is filed. Hence, it would seem that you would be exempt from both filing or having any Ohio Estate Tax Liability.
In short, there would be no Federal or Ohio Estate tax liabilities in your case! |
