IRS sets out rules to determine if you have to file. Having the condition you cite above is not one they automatically exclude. So read the instructions for 1040 for 2018, still in draft form. See Charts A, B , and C.
If you're taxable income is $0 - your tax liability would be $0 , therefore you'd be filing for a refund of any Federal Income taxes paid during the year & chances are - the Federal Government will not care whether you file or don't file. So the question you have to ask yourself is; Did you pay any Federal Income Taxes & would it be worth the filing fees to file. For example; if you paid $100 in Federal Income Taxes during the year and it will cost you $150 to file your return - it wouldn't be worth filing. Whereas if you paid $1500 in Federal Income Taxes & it costs you $150 to file - it probably will be worth filing to get the $1350 back. BUT BE AWARE - depending on which state you reside in, TYPICALLY IF YOU FILE A FEDERAL RETURN - THE STATE WILL BE LOOKING FOR A STATE RETURN AS WELL. So I would also look at your state's filing requirements to make sure you're following their laws as well!!
