The heightened sensation of a taxgasm occurring before the correct or assigned time.

Usually experienced by CPA's and other tax professionals, this occurs when a preparer believes that a tax return has been completed perfectly and later has it returned by the reviewer with 15 review points resulting from egregious errors. The preparer then realizes that the elation experienced earlier was premature.

"I taxgasmed when that return was finished, then I realized that I forgot about the Alternative Minimum Tax calculation. Another case of premature etaxulation!"
