Receiving IRS Form 1095-B does not mean that you have to file taxes. Visit irs.gov/uac/Do-I-Need-to-File-a-Tax-Return? to find out if you have to file.
If you have additional questions about whether or not you need to file, go to IRS.treasury.gov/freetaxprep, or call 2-1-1 and ask to be connected with a tax assistance site near you.
