I've been living in a temporarily-retired state for the past three years thanks to an unused college fund (I was able to fund my own tuition at the time), but anticipate a self-employed income of about 25,000 for the rest of 2016 based on what I made several years ago managing two home businesses. This is a niche market with a lot of assured clients, so I'm confident I can predict this income. Can, or should I file with anticipated income for the rest of 2016?
