…it may very well be that businesses are shifting as much income and production as possible to this year. Arthur Laffer writes in the Wall Street Journal June 6:
On or about Jan. 1, 2011, federal, state and local tax rates are scheduled to rise quite sharply. President George W. Bush's tax cuts expire on that date, meaning that the highest federal personal income tax rate will go 39.6% from 35%, the highest federal dividend tax rate pops up to 39.6% from 15%, the capital gains tax rate to 20% from 15%, and the estate tax rate to 55% from zero. Lots and lots of other changes will also occur as a result of the sunset provision in the Bush tax cuts.
Tax rates have been and will be raised on income earned from off-shore investments. Payroll taxes are already scheduled to rise in 2013 and the Alternative Minimum Tax (AMT) will be digging deeper and deeper into middle-income taxpayers. And there's always the celebrated tax increase on Cadillac health care plans. State and local tax rates are also going up in 2011 as they did in 2010. Tax rate increases next year are everywhere.
Now, if people know tax rates will be higher next year than they are this year, what will those people do this year? They will shift production and income out of next year into this year to the extent possible. As a result, income this year has already been inflated above where it otherwise should be and next year, 2011, income will be lower than it otherwise should be.
Laffer believes that allowing the tax cuts to expire will result in an economic collapse next year that will dwarf what we’ve seen so far. To be sure, a sudden, massive tax increase in the middle of a weak economy will not end well.
