The IRS defines “Tax Gap” as,
[T]he difference between the amount of tax that taxpayers should pay and the amount that is paid voluntarily and on time. The tax gap can also be thought of as the sum of non-compliance with the tax law.
There are 3 components of the Tax Gap:
- Nonfiling;
- Underreporting; and
- Underpayment.
The IRS says that,
[U]nderreporting of income tax, employment taxes and other taxes represents about 80 percent of the tax gap.
The single largest sub-component of underreporting involves individuals understating their incomes, taking improper deductions, overstating business expenses and erroneously claiming credits.
Individual underreporting represents about half of the total tax gap. Individual income tax also accounts for about half of all tax liabilities.
Authors Prediction: Even before our mild recession became a full-blown one, Obama had vowed that one of his priorities would be to close the Tax Gap. Now, with the federal government hemorrhaging money like Bonfire of the Vanities’, Sherman McCoy, you can expect the IRS to redouble its efforts to enforce compliance and collect back taxes in 2009 and beyond.
For more information on the Tax Gap and the IRS’s plans for closing it, go to FS-2005-14, March 2005.
