Not married single rate no children/child support. you owe money. how ever if you can hold out against the attempts by govt to chastise you. THERE IS NO FED income tax on wages. FED court ruled that wages are EQUAL/FAIR/EXCHANGE OF SERVICE. ASK THEM TO PHYSISCALY SHOW YOU THE LAW.- THEY CAN'T. but they will attempt to lien your home garnish wages etc. state,local taxes, investments,bank accounts are different and fall under diff laws and are on the books. get married have kids. P.S you do have to file. that's a separate fine. even if you declare nothing.
You will probably have to pay, not receive, my adjusted income is less than $5,000.00 and IRS says I owe $889.00. I travel extensively in my work showing my mileage to be more than my income and still they say I owe. Many factors depend on the disposition of your taxes, you can't just say, "How much will I get back"
