DOR Technical Information Releases

Technical Information Releases (TIRs) inform taxpayers and tax practitioners of DOR's response to changes in federal or state tax laws or to court decisions interpreting those laws. A TIR states the official position of the Department of Revenue, has the status of precedent in the disposition of cases unless revoked or modified, and may be relied upon by taxpayers in situations where the facts, circumstances and issues presented are substantially similar to those in the TIR.
