Do I need to file taxes quarterly if I am self-employed (no matter what), or are there circumstances in which I can file at the end of the year?
For example, if I were employed at another job for which I had taxes withheld, especially if the withheld amount is greater than the owed amount. Is it still required? If so, could I file for both quarterly (and not pay anything) to keep as much in assets as I can?
