Sorry to ask a thick question but what counts as taxable or non-taxable interest?
To start, I'm going to assume these are all 'foreign' bank accounts. The interest from any bank account (foreign or US based) is taxable for a
US tax return.
The ING accounts' interest is already taxed before it's deposited.
I'm guessing the tax witheld is the 20% for HMRC. This is correct for a
UK tax situation (provided your total income [all sources] is over the UK personal allowance).
I have a joint current account (no interest), a newly-opened sole current account (no interest) and three ING UK accounts (interest bearing, about $50 interest received).
You have two issues for a US situation. First, reporting on 1040, and second, reporting on an FBAR. For the 1040, the amount you report is the gross amount of interest you recieve, not the amount after UK tax has been witheld.
fwiw I answered yes, no, no on section 3 of schedule B, but that's all I've put there. I've put the approximately $50 interest as non taxable income on 1040.
There are two parts to question 7a. You're probably aware of how to calculate the amount for an FBAR (the second part), but I'll go over it anyway.
For the joint account: it's the highest balance at any time during the year. Do not calculate 1/2 of the highest balance, use the full maximum balance.
For the sole current account, do the same.
For each of the ING accounts, do the same.
Add the highest balances for all 5 accounts. If this is over $10,000, you must file an FBAR listing all 5 accounts. Your answer to the second part of question 7a of the schedule B would reflect this.
