I have a 1099-MISC from an employer. I do NOT own a business. Why is TurboTax making me fill out Schedule C?

Well, for one thing if you are an employee there is no reason for the employer to issue you a Form 1099-MISC or a Form 1099-NEC.

Look at the Form 1099-MISC - Is your payment reported in box 3?  If so, see what the IRS considers income in box 3 -

Box 3. Generally, report this amount on the “Other income” line of Schedule 1 (Form 1040) and identify the payment. The amount shown may be payments received as the beneficiary of a deceased employee, prizes, awards, taxable damages, Indian gaming profits, or other taxable income. See Pub. 525. If it is trade or business income, report this amount on Schedule C or F (Form 1040).

The questions in TurboTax regarding Form 1099-MISC are designed to insure the income on it is properly handled on your tax return. You will need to indicate that the income is not associated with your main job, is not recuring year to year and the activity was not engaged in to earn a profit in order for the income to not be treated as self-employment income. If any of those three conditions are not met, then it is likely the IRS will treat the income as self-employment income. Also, those questions will not appear on your tax return, they are just asked to help determine the correct way to report the income on your tax return.

The question is why did you receive income that was separately reported on a 1099.

Generally speaking, everything that your employer provides as compensation for services given should be wages reported on your W-2. If this was a bonus, or something else given in recognition of your service, it should have been reported on your W-2. The proper procedure is to contact the employer first and ask them to issue a corrected W-2 and cancel the 1099. If they refuse to do this, you can report the income using form 8919 with code H. This is for a 1099 that should have been reported as W-2 wages. I believe that in the 1099 interview, there is a box you can check on a page listing special circumstances for, “these were wages from my employer that should’ve been on my W-2.”

The other possibility is that you work in an industry where you receive bonuses directly from the manufacturer of things you sell, rather than from your employer. These are sometimes known as SPIFFs, or performance incentives. For example, you work for an appliance store and you receive regular wage from your employer, and then you receive a bonus check directly from thr manufacturer for their appliances that you sell.  The spiff is not considered compensation for work performed, because you are not working for the payer.  In this case, the spiff is properly reported as 1099-MISC income that is not related to your regular job.

Lastly, of course, if you are a contract worker and do not receive a W-2, then you are self-employed, whether you want to be or not.  The important difference is between employees and contractors are described here.

If you don’t receive a W-2, and you only receive a 1099, then you will need to go through a complicated process to have the IRS determine what kind of worker you really are.
