Hello,
I have 3 saving accounts based abroad (EU zone). How do I report the interest earned on those accounts ?
In the interest income section, disclose that income in the same way you would disclose had you received a 1099-INT. If the interest is earned in a foreign currency, you can use the exchange rate here:
