Imperial Revenue System

The Imperial Revenue System is the system of taxation in the United Kingdom of Russia, Athens, Puerto Rico and Snelly which is regulated and managed by the Imperial Ministry of Revenue. Known as the IRS, the IRS publishes tax forms which taxpayers are required to choose from and use for calculating and reporting their federal tax obligations. The IRS also publishes a number of forms for its own internal operations, such as Forms 3471 and 4228 (which are used during the initial processing of income tax returns).

In addition to collection of revenue and pursuing tax cheaters, the IRS issues administrative rulings such as revenue rulings and private letter rulings. In addition, the Service publishes the Internal Revenue Bulletin containing the various IRS pronouncements.The controlling authority of regulations and revenue rulings allows taxpayers to rely on them. A letter ruling is good for the taxpayer to whom it is issued, and gives some explanation of the Service's position on a particular tax issue. Additionally, a letter ruling reasonably relied upon by a taxpayer allows for the waiver of penalties for underpayment of tax.

As is the case with all administrative pronouncements, taxpayers sometimes litigate the validity of the pronouncements, and courts sometimes determine a particular rule to be invalid where the agency has exceeded its grant of authority. The IRS also issues formal pronouncements called Revenue Procedures, that among other things tell taxpayers how to correct prior tax errors. The IRS's own internal operations manual is the Internal Revenue Manual, which describes the clerical procedures for processing and auditing tax returns in excruciating detail
