“Why me?” is the plaintive cry from most taxpayers facing an examination from  the IRS. You can ask the auditor why all day long, but he’ll just shrug and say, “I don’t know. I’m just doing my job.” Once in a while an auditor may give you  her best guess as to why you were selected, but don’t count on it. To be fair, there tends to be a good reason a tax return is flagged for an  audit. Sometimes it is a random spin-of-the-wheel choice, but in most cases  there’s a catalyst to the red flag. So here’s some insight: Dif Scores. Electronic filing has made it much easier for the IRS to  gather data in order to analyze population groupings, standards and trends. A  simple act of feeding in parameters to existing data can provide information  regarding queries like: How many home owners exist in a certain nine-digit ZIP  code, or what is the average income in Wichita? The IRS developed a method of computer scoring called the Discriminant  Function System (DIF) score which rates the potential for change based on past  IRS experience with similar returns. The Unreported Income DIF (UIDIF) score  rates tax returns for the potential of unreported income. The highest-scoring  returns are reviewed by IRS personnel and from there some are selected for audit  with pointers to items on the return that need review. So: You might be audited if you live in Bel Air, pay DMV tags for a  Lamborghini, and pay interest on a million-dollar mortgage yet declare less than  $100,000 of income. Although there may be a very good reason for this–maybe you  earned millions in 2010 and left the workforce in 2011 to kick back and spend  your fortune– the IRS will suspect you aren’t reporting all of your income, and  will want to take a peek. Abusive tax avoidance transactions. Some folks are audited because  they participate in abusive tax avoidance transactions. The IRS identifies  promoters and participants usually from tipsters or from lists of participants  that promoters have been court-ordered to turn over to the IRS. Be very wary  when investing into those “too-good-to-be-true” tax shelters. Always run them by  your tax pro. Related examinations. This is a typical scenerio for a general contractor who uses subcontractor labor.   The IRS noticed that he had neglected to send out Forms 1099 to his  subcontractors and then identified the subcontractors and checked their tax  returns to see if they had declared the income–several had not. The agency  pounced on those who had not – easy prey. I’ve had clients tell me that since  they didn’t get a 1099, they didn’t think they were required to report the  income. Not so. If you have self-employment income of $400 or more, you are  required to file a tax return whether you receive a 1099 or not.  If you pay anyone a fee to do work for you – such as a photographer or accountant – that exceeds $600 a year, you are required to send them a 1099-MISC reporting the amount paid in a calendar year.  Please contact me for details of how you can remain in compliance with this little-known IRS regulation. Specific market segments. Every year the IRS selects a particular  industry for compliance examinations. In the last couple of years they have  concentrated on foreign trusts with the idea of uncovering unreported income  from offshore accounts. A few years ago they looked at attorneys incorporated as  Sub S corporations attempting to reclassify dividends as wages for those who  take low salaries but large distributions thus saving money on employment taxes.  One year they went after servers in restaurants to collect on unreported tip  income. Every year the agency chooses an industry to scrutinize based on  suspected abuse hot spots. Automatic Underreporter Program (AUR) and Information Matching. Employers, banks, brokerage firms, payers of independent contractors all  file documents with the IRS and send the same documents – Forms 1099, W2, 1098,  K-1, etc. to taxpayers. If you neglect to report any of the data on these forms,  or report an amount different than what is on the form, the IRS picks up on it.  Usually, it sends out a letter CP- 2000  relaying the information and billing the taxpayer for additional taxes.  Sometimes an agent shows up on your doorstep. Amended returns are often times flagged for audit, especially if the  information you are changing involves increasing deductions in red flag areas  such as travel, meals and entertainment and automobile expense. Don’t be afraid to amend if you have cause. However, if you are amending your  income tax return, be sure you can substantiate all deductions and income. Reprinted from Foxbusinessnews.com
