You can always file a return, even if you don't owe any money. If you don't file, and based on 1099 information reporting and other sources, IRS determines you may owe some tax, they will create a substitute return and open an assessment for that amount. If you are entitled to a tax refund or tax credits, you also can't claim these unless you file. I'd at least prepare a draft return to see if it's worth filing.
