I have a W2 job and did a one-time consulting work on the side (for 2 weeks) in July for a different organization. I had all the equipment I needed already (phone, computer, office software, etc). Compensation was shy of $4000.
I don’t know if/how I could write off any of the items I used/already had. Now, it is almost the end of the year and I am in need of a new computer and office software. Could I purchase those items now and claim a deduction? I am not sure if next year I will have another one-time gig for 2024.
