I was full-time 1099 for the first six months of the year. I am now W-2 but do have a small self-employed side gig that may or may not earn a bit extra income for the remaining months. Am I still able to deduct the self-employed expenses such as portion of phone/computer used for work, etc. even if some months might not have self-employed income? Or can I only deduct those in a month where I have specifically earned side gig 1099 income, and does it matter how little/much I earned?
