FYI Publications - Income Tax
What is happening with FYIs?
Over the next few years, the Department of Revenue will be publishing new and improved guidance in the form of general tax guides and supplements on specific tax topics. These new guides and supplements will replace the “FYI” publications previously issued by the Department. We will indicate on the Department’s website when an FYI has been discontinued and refer to the new publication which has replaced it.
