1099-NEC Sporadic Activity
I am retired and do not currently operate a business. For the first 5 years after retirement as a professional, I created a S-Corp and conducted a few small service jobs. My income never amounted to more than $3000 per year and I submitted an Income Tax filing as a S-Corp. About 3 years ago, I dissolved my company and have not done any work since. I have no business plan and do not seek work of any kind. Last summer (2023) I was called by a very small non-profit in my town and asked to fill in a position while they hired a replacement employee. I did so and worked a few hours per week for about 1-1/2 months as a non-employee. I was paid for that work and it amounted to $2100. The non-profit filed the payment on a 1099-NEC.
I am not sure what to do. I don't mind paying taxes on it but I certainly don't want to create a new business just to be able to report this one-time, sporadic work. I don't mind completing a Schedule C but I do not own a Sole Proprietorship. Also I don't have a Principal Business Code.
Please advise me on how to hand reporting this income from a truly Sporadic Activity.
