Estimated taxes for single-member LLC taxed as an S-Corp
I have a single-owner LLC and have elected to be taxed as an S-corp (effective 1/1/18). I take a salary and taxes are taken out of my paycheck. How do I calculate my estimated taxes? Before I was taxed as an S-corp it was straightforward. But now some taxes are taken out of my paycheck--do I account for those taxes when calculating what I will pay for state and federal quarterly estimated taxes?
