Move them up, or move them back? Make it July and October, instead of June and September, so that they are all three months apart? That makes sense but it screws up a lot of states who conform to most federal deadlines and have a fiscal year that ends in June,
Originally it was March, June, September and December. Middle of the third month of the quarter made it more comparable to withholding from each paycheck. Then it was obviously easier to figure the last quarter once the books were closed for the year, so that was changed to January. Then they changed the 1040 due date from March 15 to April 15, and it made it easier to estimate the first quarter once last year's tax was known.
