The title given to the hearing was "Cl
osing the Tax Gap: Lost Revenue from Non-Compliance and the Role of Offshore Tax Evasion."
At the outset of his testimony, George made clear the issue warrants serious and immediate attention. "Finding effective solutions to address the tax gap and its components would yield substantial additional tax revenue," he said.
The tax gap is defined as the difference between the estimated amount taxpayers owe and the amount they voluntarily and timely pay for a tax year. The gross tax gap, which is the amount that is owed by taxpayers before collections resulting from IRS enforcement actions and other late taxpayer payments are taken into account, is estimated to be $441 billion annually, George noted.
According to George, the underreporting of income taxes comprises the largest component of the tax gap at $352 billion annually. Individual taxpayers are responsible for the largest share of the underreporting tax gap at $245 billion.
However, Russell waved a cautionary flag in his testimony. "The tax gap estimates are generally outdated because they are for tax years of a decade earlier, so their usefulness may be limited," he said. "Recently, the IRS commissioner testified that he believes the annual tax gap is at least $1 trillion," George added.
George offered a series of recommendations which, in his opinion if taken together, would significantly improve tax compliance, including:
- more effectively prioritizing high-income taxpayers;
- a stronger impetus by the IRS Large Business and International Division to identify corporate non-compliance;
- addressing the negative impact of Internet platform companies on tax compliance;
- dealing with the ongoing problem of adequate resources for IRS and its potential impact on enforcement revenue (he highlighted the reductions in most types of examinations and the nonpayment of taxes owed); and
- improving international tax compliance.
