Gone...a few years ago...2012 or 2015, according to the IRS...there were 15 farmers/ ranchers in the entire United States that would be subject to “Death Tax” rates...I doubt that figured has moved much since that time. The “Death Tax” is a rallying call for the right-wing of America...it just simply is not a reality. Plus, I bet a farmer/rancher with a net worth of $11.5 M, can probably afford an attorney and mitigate the affects of the death tax considerably.
Your supposition that Biden and Congress will drop the threshold of the Death Tax is mere supposition on your part. There is NO fact to back up your fear!
When was the last time Congress raised your income tax...or your estate taxes?
