As we enter the final days before IRS filing is due, many are considering the mind-numbing complexity of the U.S. tax code.  It is estimated that taxpayers and firms spend over 6 billion hours per year attempting to correctly file tax returns.  Not only does this figure represent the equivalent of millions of workers, but it also pulls billions of dollars out of more productive uses.  According to the IRS Taxpayer Advocates, who reported to Congress in 2010, the complexity of the U.S. tax code is driven, in part, by continual changes to the system as the federal government attempts to squeeze more and more out of taxpayers.  In the past decade there have been approximately 4,400 tax code changes resulting in 3.8 million words to document the American taxation system.  Since 1913, the tax code has ballooned from 400 to 72,536 pages in July 2011.  Worse yet, the blog Political Calculations expects that number to jump to 74,944 in 2012.

The irony of such an intricate tax system is that complexity is connected to compliance.  This is true both of honest taxpayers and evaders.  A recent report stated that IRS help centers provided wrong answers to taxpayer questions almost 30 % of the time.  Even the 90,000 plus IRS workers are unable to keep up with this ever-changing system.

The obvious question is why the complexity?  Why does the federal government try to increase revenue through such a complex set of rules?  The answer goes back to the fundamental role of government.  If the government wants more of something it subsidizes it, and if it wants less of something it taxes it.  A subsidy to the corn industry helps farmers grow more corn and more ethanol is produced.  A tax on imported sugar keeps sugar growers in America happy by keeping out global competition.  So, Congress uses the tax code to regulate the market in order incentivize specific behavior.  In other words, the complexity of the tax code is due to the unbridled desire for Congress to regulate.  The complexity is not a necessity to ensure Congress replenishes its coffers each year.

Congress loves to provide incentives to the tax code.  Any problem it wants to solve, use the tax code.  Any behavior it wants to change, use the tax code.  Any industry it wants to prop up or diminish, use the tax code.  President Obama’s stimulus package, which passed early in his presidency, added 300 pages to the tax code.  Manipulation of the tax code has simply become de facto government regulation.  This is not a new practice for Congress or the President.  Ever since the 16^th Amendment, the federal government has increasingly used income taxes (on individuals and businesses) to regulate, but the ridiculous nature of this ever-increasing complexity is out of control.

Pursued by industry in order to impact individual incentives, federal tax deductions exist for children with an overbite who enroll in clarinet lessons and whaling captains can deduct ship repairs even though whaling in the U.S. is illegal.  The government also provides many additional deductions of impact healthy behavior from quitting smoking to doctor-ordered exercise.  While these may be a benefit to your health, is it prudent to add to the increasing complex system with additional changes, loopholes, and deductions?

Sadly, simplifying the tax code has become a partisan issue pitting those in favor of smaller government versus those who look to government to solve economic and social problems.  This is a mischaracterization of the issue.  Tax complexity is a massive waste of resources.  No matter if you are conservative or liberal, the billions of dollars invested in tax compliance are wholly unnecessary.  There may be differences on how to use the billions of dollars that would be saved with a simple system, such as a flat tax or a consumption tax, but all taxpayers should agree that 90,000 plus IRS workers and $430 billion spent each year on compliance is a colossal waste.  Now let’s convince Congress to change the system.
