In almost all cases, your employer should pay all your wages on a W-2. They may be trying to avoid their responsibilities for employment taxes, unemployment insurance, workers comp, and other costs. However, there are a few fields where separate 1099's for commissions are allowed, such as real estate and auto sales ("spiffs"). Can you tell us something about the work you do? Is the commission paid by your employer, or is it paid by an upstream vendor and passed through your employer?
