“We investigate
the conventional wisdom that privately-held firms engage in more tax planning
than do publicly-held firms. Private firms are believed to face lower nontax
costs of tax planning relative to public firms, allowing them to engage in more
tax planning. However, empirical evidence of U.S. private firm tax planning is
limited, primarily because of difficulty in obtaining private firm data. We
make use of detailed administrative data from the Internal Revenue Service,
which covers virtually all U.S. public and private firms. Using a variety of
tax planning measures, and contrary to conventional wisdom, we find no evidence
that private firms engage in more tax planning relative to similar-sized public
firms in the same industry. Moreover, some evidence suggests that private firms
actually engage in less tax planning. These findings persist across different
measures of tax planning and are not explained by firm characteristics commonly
used to explain tax behavior. These results have important implications for
researchers as well as for policymakers and managers.”
Here is some
background about the setting for this: Conventional wisdom in the biz (drawing both
on field knowledge and empirical research into the tax and accounting behavior
of publicly held companies) holds that, at such companies, agency costs at the
managerial level, and/or surprising lacunae in capital markets’ grasp and use
of information, cause managers to care more about reported profits than true
after-tax profitability. Hence, they may do less to reduce taxes than they
ought to do, from the perspective of a buy-and-hold shareholder, because they are
so focused on the financial accounting measure that they will be reporting in
their 10-Ks. (Shareholders have every reason to want higher true profits, but
higher reported profits in a given year do nothing for them unless it boosts
the stock price when they happen to be selling.)
Anyway, an
obvious inference would be that private firms, since they’re not filing 10-Ks or
similarly engaged in trying to impress credulous investors, are going to do
more tax planning than the public firms. And agency costs in this regard may recede
if you have high-percentage owner-managers who are playing with their own
money. It has therefore been presumed that “private firms” should be expected
to do more extensive and (given low penalties) aggressive tax planning than
public firms.
When we think of “private
firms” in the U.S. setting, we may mainly think about passthroughs, such as
partnerships and S corporations. But these are NOT the focus of the Hoopes
paper; hence, we learn nothing about them directly (although it’s open for
further thought whether, and to what degree, the findings might affect our
assumptions or understandings about them). Instead, the paper uses previously
un-studied IRS tax data to look at private C corporations, which have chosen to
be subject to the corporate tax (and then potentially the shareholder-level tax
upon selling shares or receiving corporate distributions) even though they are
not publicly traded.
To quote Butch
and Sundance, but with an opposite implication (one is asking “Are they stupid?”
rather than “How can they be so smart?"): Who are these guys? In the aftermath
of the 2017 tax act, private C corporations may be drawn by the 21 percent
corporate rate, which is much lower than the top rate of 37 percent for
individuals. There has been debate in the biz regarding how great a deal this
actually is, given the potential second level of tax (plus the chance that the corporate
rate might be raised in the future), but at least it’s a big up-front discount that
might attract some savvy operators. Pre-2017, however, when the rate difference
was only 35 percent corporate versus 39.6 top rate for individuals, the conventional
wisdom was that you just shouldn’t be a C corporation unless your aim of being
publicly traded effectively forced it on you.
The literature
offered some interesting answers to why there might be private C corporations. E.g., one might be planning to go public
soon, and in that regard want to be able to offer key employees incentive stock
options, or appeal to venture capitalists who were familiar and comfortable with
the C corporation form. One might really like access to standard corporate law
(if one was actually incorporating, not just checking the box for C
corporation tax status despite using some other sort of legal entity). Or, as
recent work by Emily Satterthwaite suggests is possible, one might simply be relatively
uninformed and ill-advised regarding one's tax planning choices.
OK, back to the Hoopes paper. It uses tax data to compare public with private C corporations when they
otherwise look extremely similar – same size, industry, etcetera. More
specifically, it uses a matched pair design, under which each public firm is
matched to a private firm that is in the same industry and similar in size. As
to these matched pairs, it finds no evidence (using multiple specifications) that
the private firms domore tax planning than the public firms. This is
potentially contrary to what one might have expected, under the standard view as
described above.
How might we
explain this result? Perhaps pre-2017 C corporations are an odd group, partly
including those who are simply bad at tax planning (or otherwise atypical of
private firms generally). Surely the post-2017 group will be quite different,
given that it will now attract more players who are interested in the up-front
tax rate difference. Perhaps these pre-2017 private corporations had their own
agency costs with respect to their tax decision-makers, or did not have as good
access to the best tax planning advice. Perhaps agency costs at public C’s can
lead to “too much” tax planning from the shareholders’ standpoint, as well as “too
little.” For example, complex structures that are rationalized on tax planning
grounds may also serve managerial objectives of diverting funds from the
shareholders’ pockets to the managers. Or managers may have an unduly short
time horizon if they anticipate exiting the firm (or, at least, exercising the
options) before any dubious tax planning that they have done catches up with
the firm.
But whatever the
explanation, and whether or not one considers it illuminating as to private
firms generally, and/or likely to persist in the significantly altered
post-2017 business tax planning environment, it’s an interesting result that
merits attention.
