The tax gap represents the difference between the taxes that should be paid to the government and the amount actually collected on time. According to the IRS, this gap results from various forms of non-compliance, including underreporting income, underpaying taxes, and tax nonfiling. For tax years 2014-2016, the IRS estimated the annual gross tax gap averaged about $441 billion, illustrating a substantial loss in potential revenue that could fund essential government services.
How Does the Tax Gap Occur?
The IRS breaks down the tax gap into three primary components:
- Underreporting of Income: The largest contributor, this occurs when taxpayers intentionally or accidentally fail to report all income. This includes unreported side cash jobs, overlooked interest earnings, or overclaimed deductions.
- Underpayment of Tax: Taxpayers correctly report income but do not pay the total tax due by the deadline. Financial hardship or misunderstanding tax liabilities can cause this.
- Nonfiling of Returns: Some taxpayers fail to file tax returns altogether, either deliberately or unknowingly. This leads to unpaid taxes that the IRS cannot collect without a filed return.
The IRS’s estimates show that these issues collectively create a vast tax revenue shortfall that undermines government funding.
Historical Context and Measuring the Tax Gap
The IRS has monitored the tax gap for decades, employing increasingly sophisticated methods to estimate its size. Since direct measurement is impossible for unreported income, the IRS uses data from random audits (such as the National Research Program), third-party income reports (e.g., W-2s and 1099s), and economic analysis to infer compliance levels. This approach helps the IRS identify trends and focus resources where non-compliance is most common.
Examples Illustrating the Tax Gap
Common real-world cases that contribute to the tax gap include:
- A small cash-only business owner who fails to report all cash earnings.
- Freelancers earning income without filing returns or paying self-employment taxes.
- Investors missing or misreporting income on forms like 1099-DIV or 1099-B.
- Self-employed individuals who underestimate or delay quarterly tax payments.
These examples show the diversity of taxpayers and circumstances involved in non-compliance.
Impacts of the Tax Gap on Society
The tax gap affects everyone:
- Reduced Government Funding: Billions lost mean less money available for schools, infrastructure, defense, and social programs.
- Increased Burden on Compliant Taxpayers: To offset uncollected taxes, compliant taxpayers may face higher tax rates or reduced services.
- Erosion of Fairness and Trust: Large tax gaps fuel perceptions of an unfair tax system, weakening public confidence.
How the IRS Tackles the Tax Gap
The IRS employs several strategies to reduce the tax gap:
- Third-Party Information Reporting: Requiring employers, banks, and other entities to report income directly to the IRS helps ensure accurate taxpayer reporting. This is a key tool in reducing underreporting.
- Targeted Enforcement: Audits and penalties focus on high-risk noncompliance areas, encouraging accurate filing and payment. Learn more about IRS audits on FinHelp.io.
- Taxpayer Education and Services: The IRS provides resources, guidance, and assistance to help taxpayers understand compliance requirements and avoid honest mistakes.
- Technology Upgrades: Modernizing IRS systems helps detect non-compliance earlier and process returns more efficiently.
| Source of Tax Gap Contribution | Description | Example |
|---|---|---|
| Underreporting | Income or deductions are not fully or accurately reported. | Cash payments not declared by a contractor. |
| Underpayment | Full tax owed is not paid by the deadline despite accurate reporting. | Business files return but cannot pay full tax due. |
| Nonfiling | Tax returns not filed when legally required. | Individual above filing threshold who avoids filing a tax return. |
Common Myths About the Tax Gap
- Myth: Only wealthy people cause the tax gap. While high earners contribute, small businesses and individuals with income not reported to the IRS are significant contributors.
- Myth: The tax gap is mostly intentional evasion. Many errors are unintentional, stemming from misunderstandings or oversights.
- Myth: Auditing everyone would solve it. The IRS has limited resources and focuses audits where they will have the most impact to balance fairness and efficiency.
Frequently Asked Questions
Q: Does the tax gap include uncollected taxes from illegal income?
A: Yes, IRS estimates try to include all income types, but measuring illegal income is inherently challenging and based on broad assumptions.
Q: How is the tax gap measured?
A: Through detailed audits (National Research Program), third-party income data, and economic modeling to estimate compliance and gaps.
Q: What is the net tax gap?
A: The net tax gap is the amount of unpaid taxes remaining after IRS enforcement efforts recover some owed taxes.
Q: Can honest mistakes contribute to the tax gap?
A: Yes, errors like missing income or misclaimed deductions unintentionally add to the gap, highlighting the importance of accurate tax filing.
