foreign inheritance tax Savings Bond Interest 1116 K-1

Hello,

I inherited a 30 yr. US savings Bond and paid German inheritance tax on the total bond value of which appr. 75% was interest. I will enter the foreign taxes paid on form 1116 passive activity form Part II line A(t).

The problem is that in the foreign country, I only have to pay 11% inheritance tax over a certain amount.

Can I just use the 11% tax, I have more than the foreign exclusion?

Or:

Must I use a multiplication factor?

Foreign taxes / (Tax free Amount + Foreign Inheritance Interest)

 

Or is there another way.

 

I filled out the Schedule K-1 Worksheet  Estates And Trusts, but there was no tax-exempt interest. On schedule B the total K-1 interest in included.
