I expect to file a self employed return next year as I will no doubt cross that $400 threshold by then.
I don't understand how to determine the amount I need to pay quarterly. I keep records, and right now I estimate that between when I started in June and today I owe about 300 in tax. Is that what I would submit for a quarterly payment with the idea that next quarter may be less or more, or do I need to assume I'll owe 1200 (300x4 quarters) so just pay 300 each quarter?
I worked full time last year at a company and paid taxes the "normal way."
Also, can I file to do quarterly payments electronically? I've seen the paper form and it's extremely confusing.
