Question Should self-employment taxes be paid quarterly or yearly? Answer Generally, if you determine you need to make estimated tax payments for estimated income tax and estimated self-employment tax, you can make quarterly estimated tax payments or pay all of the amount due on the first quarterly payment due date. Special rules apply to farmers and fishermen. Farmers and fishermen make one required payment or pay in full with their tax return when filed by a certain date.
