When a husband dies and all assets are in his name, what does the wife beneficiary pay in taxes.

Florida has no estate tax, nor inheritance tax.  The federal estate tax currently has an exemption from the tax for the first $5,250,000 of assets for each spouse, for a total of $10,500,000 for both spouses.  If your husband's asset total $1.5 million, then there will be no estate tax to be paid to the IRS.  All that you will need to do is transfer the assets to your name from your deceased husband's name.  Assuming the assets are titled in his name alone, it will be necessary for you to probate your husband's estate to get the assets transferred into your name. You should consult with an experienced Florida probate attorney to determine exactly what actions will be necessary to transfer title of the assets to you.
