My response added questions. The primary question was simply, “How does one measure complexity?” I elaborated on my question: “Number of words? Not necessarily. There is something somewhere floating about that deals with ‘What is the longest Code section?’ but I don’t have a cite offhand. Number of challenging computations? Number of difficult definitions? Number of exceptions? Number of exceptions to exceptions? Difficulty of application? The black letter law ‘gifts are excluded from gross income’ is simply stated, but the question ‘What is a gift?’ requires complicated analysis to come up with something that separates gifts from payments for services. Does it matter if the provision affects 10 people or 1000 people? In other words, is something with a complication level of 6 (whatever that means) affecting 200 people (1200 points) more complicated than something with a complication level of 8 affecting 5 people (32 points)? Some of the most complicated things are the transition rules and effective dates, which technically are in the amending act and not in the Code itself.”
In a follow-up, the reader shared the link to Janet Novack’s Forbes article, The Most Confusing Part of the Income Tax Code, which describes ten areas of tax law that are complex. The reader then asked, “Should you consider the number of tax cases litigated regarding a particular section? Should you consider the National Taxpayer’s Advocate Report 2010 stating that 80 million taxpayers are affected by family status issues such as earned income credit, marital status, child tax credit, and child and dependent care credit? Should you consider if you are wrong about filing status the taxable income and total tax owed or refunded is affected? Should you consider if section 107 parsonage allowance with only 81 words is extremely complex because it has resulted in hundreds of tax cases about the law and whether the section is constitutional?” In yet another follow-up, he asked, “Should you consider the [flush language] sentence from Section 509(a)(4) [509(a)]? Should you consider the premise that if tax experts or AICPA argue for simplification of particular tax codes [sections] then those tax codes [sections] are too complex?”
I don’t agree with the proposition that every code section and regulations section is complex. For example, section 701 provides, simply, that partnerships are not subject to the federal income tax. But I think there is unanimous agreement that many, perhaps most, Code sections are complex. And I think it is safe to conclude that there is unanimous agreement that too many Code sections are complex.
In addition to the issue of deciding which factors should enter into the determination of complexity and the issue of determining how much weight should be assigned to each factor, there is the further, sorry, complication caused by the existence of different types of complexity. For example, some Code sections are complex primarily, or even solely, because of computation complexity. Section 82, prescribing the calculation of social security gross income, falls into this category. Another sort of complexity is interpretational complexity. For example, the flush language of section 509(a), noted by the reader, surely qualifies, as it reads, “For purposes of paragraph (3), an organization described in paragraph (2) shall be deemed to include an organization described in section 501(c)(4), (5), or (6) which would be described in paragraph (2) if it were an organization described in section 501(c)(3).” Still another type of complexity is technical complexity, when redundancies, ambiguities, poor drafting, and slipshod organization complicate the task of trying to determine what the words mean. Often this sort of complexity arises not from any Code section in and of itself but from the intersection of multiple code sections. Yet another type of complexity is revision complexity, the confusion that results from constant changes to the provision, with effective dates, exceptions to the effective dates, grandfather provisions, and other special rules, many of which remain in the amending act but don’t end up in the Code itself.
Should the analysis be limited to entire Code sections? Or is it acceptable to tag particular subsections, paragraphs, subparagraphs, clauses, and subclauses? It is not uncommon to find a Code section with a very simple subsection (a), only to discover that it’s (b), (c), and (d) that cause eyeballs to spin around in a person’s head. Should provisions that are in amending acts but not in the Code qualify? I think so, though that technically makes the question something different from “What is the most complex Code provision?”
If the only requirement to win the complexity contest is number of words, the victor is section 341(e)(1), as described in this web page:
Internal Revenue Code Section 341(e)(1) - Its a 455 word sentence about "Collapsible Corporations"If there were a way to measure the amount of money expended in an effort to understand and comply with specific Code sections or components thereof, perhaps that would be the best measure of complexity. I don’t think information of that sort is available.
(1) Sales or exchanges of stock for purposes of subsection (a)(1), a corporation shall not be considered to be a collapsible corporation with respect to any sale or exchange of stock of the corporation by a shareholder, if, at the time of such sale or exchange, the sum of - (A) the net unrealized appreciation in subsection (e) assets of the corporation (as defined in paragraph (5)(A)), plus (B) if the shareholder owns more than 5 percent in value of the outstanding stock of the corporation the net unrealized appreciation in assets of the corporation (other than assets described in subparagraph (A)) which would be subsection (e) assets under clauses (i) and (iii) of paragraph (5)(A) if the shareholder owned more than 20 percent in value of such stock, plus (C) if the shareholder owns more than 20 percent in value of the outstanding stock of the corporation and owns, or at any time during the preceding 3-year period owned, more than 20 percent in value of the outstanding stock of any other corporation more than 70 percent in value of the assets of which are, or were at any time during which such shareholder owned during such 3-year period more than 20 percent in value of the outstanding stock, assets similar or related in service or use to assets comprising more than 70 percent in value of the assets of the corporation, the net unrealized appreciation in assets of the corporation (other than assets described in subparagraph (A)) which would be subsection (e) assets under clauses (i) and (iii) of paragraph (5)(A) if the determination whether the property, in the hands of such shareholder, would be property gain from the sale or exchange of which would under any provision of this chapter be considered in whole or in part as ordinary income, were made - (i) by treating any sale or exchange by such shareholder of stock in such other corporation within the preceding 3-year period (but only if at the time of such sale or exchange the shareholder owned more than 20 percent in value of the outstanding stock in such other corporation) as a sale or exchange by such shareholder of his proportionate share of the assets of such other corporation, and (ii) by treating any liquidating sale or exchange of property by such other corporation within such 3-year period (but only if at the time of such sale or exchange the shareholder owned more than 20 percent in value of the outstanding stock in such other corporation) as a sale or exchange by such shareholder of his proportionate share of the property sold or exchanged, does not exceed an amount equal to 15 percent of the net worth of the corporation.
Some complexity, however, is attributable to the transaction under consideration and not to the tax law. If a taxpayer, in an attempt to end-run the system, sets up a business or investment enterprise by using hundreds of entities located throughout the world, cross-linked in complicated ways and engaging in roundabout interactions, the challenging task of applying tax law principles to the arrangement is not the fault of the Code. There also is the reality that what one person finds complicated another person understands with little effort. That, in turn, raises the question of who should be the judge of complexity. Should it be the practitioners who collaborate on ABA and AICPA commentary and proposals for simplification? Should it be taxpayers generally? I think it should be anyone who works with the tax law. So I invite readers to nominate candidates for tax law complexity, specifically Code and Regulation provisions, whether entire sections or specific components, or intersections of multiple provisions. To keep things manageable, readers should select their one candidate for “most” complex. I understand that all of us could easily list ten or twenty or even a hundred complex provisions but the question is “most” complex. If there are sufficient nominations (and am I setting myself up for colossal embarrassment if only two or three readers submit entries?), I will then try to learn how to set up an online poll that permits everyone to vote (and I welcome suggestions on how to do that, and, at the risk of making this complicated, ha ha, on whether the winner needs a majority or simply a plurality). Oh, nominating speeches are not required, as complex provisions speak for themselves!
