I just started my self-employed business last month and I have no idea how much I'm going to make. I don't even know how to guess. Is there a minimum to send in for quarterly taxes?
I thought I saw somewhere that I could use last year's tax numbers to avoid penalties. Does that only apply if I paid estimated taxes last year? I have my w-2 from the job I worked last year. Can I use those numbers?
I have no idea what I'm doing. Any advice would be appreciated.
