Quarterly LLC Payments

[Alex T.]

I have an LLC that was started in 2017 for my first flip. The LLC generated no taxable income in 2017, but of course, we still filed a return. We sold the flip property in 2018 for a profit. Was I supposed to be paying quarterly taxes to the IRS from the time I made a profit in 2018? My CPA never mentioned anything. I read that you don't have to start paying quarterly until the year following your first filing that has a taxable income...so for me, that would be starting in 2019. Can anyone confirm this? Thanks for the help.
