I am self-employed and pay quarterly estimated payments based on the prior year's income, although my yearly income varies. This year, I paid more in the first three quarters than I owe for the whole year. I tried to submit a $0 payment for the fourth quarter through EFTPS, but it wouldn't accept it. Do I still need to file for a quarter when I do not intend to make a payment? If so, how do I do so? I know with sales tax, I must file each period even if I don't owe anything, but I'm able to do that online without a problem. Thank you!
