No, if you received interest from a British bank account, you can report it as if you had a 1099-INT and a TIN is not required. However, if your State requires a TIN for Efiling, you can also report it as Other Taxable Income.
Scroll all the way down on the Income Topics page to Miscellaneous Income, 1099-A, 1099-C. On the next page, scroll all the way down to Other Reportable Income.
Enter a description and amount.
