If my income is all included under the foreign earned exclusion, do I need to file taxes?

I pay student loans, so have that deductible, but it is small. In 2017 I did not owe any money to the federal government or to the state, nor was I eligible for refunds.

Yes, you do.  Although your income is excluded, if you meet the filing requirements, you would still need to file to show the government you do not owe.

How can I claim child refund from abroad if my income is 12,000 as head of house hold.  And Foreign Tax Exclusion is my entire income? What can I do ?
