If I didn't get a 1099 from an employer and did not file will I still get my tax refund?

[Opus 17]

If you do not file a tax return, the IRS will not just send you free money.

You are required to file a tax return to report all your income, deductions and credits and calculate your tax owed.  You include any withholding or payments that you made.  If you owe less tax than your withholding and payments, the excess is sent back as a tax refund.  But you have to file the documents and make your claim.

You get a W2=from an employer not a 1099.  If you are self employed you might get a 1099NEC but you need to report all your income whether or not you get the 1099NEC.  You need to fill out Schedule C to report it and pay the Social Security and Medicare tax that wasn't taken out. 

You can fill out Schedule C and enter 1099NEC or Self Employment Income into Online Deluxe but if you have any expenses you will have to upgrade to the Premium or use any of the Desktop CD/Download programs. All the Desktop programs have the same forms, so you can buy a lower version.  You just get more help and guidance in the higher versions.
