The company never had any employees (except for myself, though I never gave myself salary). Of the two customers, the first paid me under $1,000 USD and the second under $2,000 USD, via check, with no contracts. I also personally deposited $5,000 into the company's bank account which then went to things like hosting fees.
The company was founded using Stripe Atlas. I registered it in the city I live in, San Francisco. I'm pretty sure it's registered in the US via Stripe Atlas. I tried to register it in California but I was unable to figure out the paperwork (certificate of good standing stuff). The company hasn't paid any taxes yet -- which might be another thing that I've screwed up.
At this point I'm wondering: what's simplest way to shut down the company and wrap up any liabilities (legal / taxes) that it may have? I would be happy to refund the customers if that makes things easier.
