I have had a side gig as a sole proprieter for 2 years and despite not having paid quarterly taxes yet, I have always had a tax refund due to my husband's tax withholdings. He has a W2 as a full-time employee and we file taxes jointly. In February of this year I incorporated as an LLC and I expect to make at least double the revenue that I did last year. How can I estimate my quarterly taxes to minimize unnecessary withholdings?
