Tax Gap 

The gross tax gap is the difference between the amount of tax imposed by law and what taxpayers actually pay on time. 

The tax gap provides an estimate of the level of overall noncompliance and voluntary compliance during the relevant tax 

periods. Tax gap estimates provide periodic appraisals about the nature and extent of noncompliance for use in formulating 

tax administration strategies. Estimating the tax gap is inherently challenging and requires assessing the merits of alternative 

methods, assumptions, and data sources. There is no single approach that can be used for estimating all the components of the 

tax gap, so multiple methods are used. The most recent estimates covering the Tax Year 2014-2016 timeframe were released 

in FY 2022. 

The gross tax gap is the amount of a tax liability that is not paid voluntarily and on time. The estimated annual average 

gross tax gap is $496.0 billion. The gross tax gap is comprised of three components: non-filing, underreporting, and 

underpayment. The estimated gross tax gap for each of these components is $39.0 billion, $398.0 billion, and $59.0 billion, 

respectively. The gross tax gap estimates are also segmented by type of tax: individual income tax, corporation income tax, 

employment tax, and estate and excise tax. The estimated gross tax gap for each of these types of tax is $357.0 billion, $41.0 

billion, $93.0 billion, and $5.0 billion, respectively. 

The net tax gap is the gross tax gap less tax that subsequently will be paid either late through voluntary payments or 

collected through IRS administrative and enforcement activities and is the portion of the gross tax gap that will not be paid. It 

is estimated that $68.0 billion of the gross tax gap will eventually be paid resulting in a net tax gap of $428.0 billion. The net 

tax gap estimates are also segmented by type of tax: individual income tax, corporation income tax, employment tax, and 

estate and excise tax. The estimated net tax gap for each of these types of tax is $306.0 billion, $34.0 billion, $87.0 billion, 

and $2.0 billion, respectively. 1
