Welcome to TaxBlawg, a resource from Chamberlain Hrdlicka for news and analysis of current legal issues facing tax practitioners. Although blawg.com identifies nearly 1,400 active “blawgs,” including 20+ blawgs related to taxation and estate planning, the needs of tax professionals have received surprisingly little attention.
The Wall Street Journal's Tax Blog gives “tips and advice for filers,” and Paul Caron’s legendary TaxProf Blog is an excellent clearinghouse for academic and policy-oriented news. Yet, tax practitioners still lack a dedicated resource to call their own. For those intrepid souls, we offer TaxBlawg, a forum of tax talk for tax pros.

As previewed by my earlier post, State Tax Notes today published an article in which I argued generally that claims that high state taxes discourage economic development may be flawed because they look at statistics selectively and fall prey to the fallacy that correlation implies causation. In particular, I considered an article by Arthur Laffer which argued that the introduction of income taxes by various states over the past fifty years has in all cases led to a decrease of per capita income when compared to the United States average per capita income in the relevant period.
Starting with the data on per capita income by state published by the Bureau of Economic Analysis of the U.S. Department of Commerce, I determined that, in fact, seven of the eleven states that have introduced an income tax have had an increase in their per capita income when compared to the per capita income of the United States as a whole. Moreover, while, as Laffer argued, gross state product did decrease for each of those states, the data for gross state product per capita can be read to indicate that the introduction of taxes had no significant effect on a state's productivity.
And for those readers who would like to see the underlying data, it is available here:
