Do The IRS And States Compare Returns: What You Need To Know?

Do The Irs And States Compare Returns? Yes, the IRS and state tax agencies do compare tax returns to ensure accuracy and prevent fraud, providing a crucial layer of oversight in the tax system. At COMPARE.EDU.VN, we understand that navigating tax compliance can be complex, and this comparison process is a key aspect to be aware of. Understanding this process helps taxpayers file accurately and avoid potential discrepancies, promoting tax compliance and preventing underreporting of income.

1. Understanding The Comparison Of Tax Returns

The Internal Revenue Service (IRS) and state tax agencies routinely exchange information and compare tax returns. This collaborative effort ensures tax compliance, identifies discrepancies, and prevents fraud. This process is a cornerstone of tax administration, helping to maintain the integrity of the tax system and ensuring that all taxpayers meet their obligations.

1.1 Why The IRS And States Compare Returns

The comparison of tax returns between the IRS and state tax agencies serves several critical purposes:

Ensuring Accuracy: By comparing federal and state tax returns, discrepancies can be identified quickly. This helps to ensure that taxpayers are reporting income, deductions, and credits accurately.
Preventing Fraud: Comparing returns helps to detect instances of tax fraud. Fraudulent activities, such as underreporting income or claiming false deductions, can be identified and addressed.
Verifying Information: The comparison process helps verify the information provided by taxpayers. This includes income, deductions, credits, and other relevant data.
Enhancing Compliance: The knowledge that tax returns are being compared encourages taxpayers to be more diligent and accurate in their filings. This enhances overall tax compliance.
Optimizing Resource Allocation: By identifying discrepancies and potential fraud early, tax agencies can allocate their resources more efficiently, focusing on cases that require further investigation.

1.2 Legal Basis For Information Sharing

The legal basis for the IRS and state tax agencies to share information and compare tax returns is rooted in various federal and state laws. These laws authorize the exchange of taxpayer information to ensure tax compliance and prevent fraud. Some key legal provisions include:

Internal Revenue Code (IRC) Section 6103: This section of the IRC outlines the general rules regarding the confidentiality of tax information but also provides exceptions that allow the IRS to disclose tax information to state tax agencies for tax administration purposes.
State Laws: State laws also authorize state tax agencies to share information with the IRS and other states. These laws ensure that states can effectively administer their tax systems and cooperate with federal and other state authorities.
Agreements and Memoranda of Understanding (MOUs): The IRS and state tax agencies often enter into agreements and MOUs that outline the specific procedures and protocols for sharing information. These agreements ensure that information is exchanged in a secure and efficient manner.

1.3 Types Of Information Exchanged

The IRS and state tax agencies exchange various types of information to ensure tax compliance and prevent fraud. This information includes:

Income Information: This includes wages, salaries, tips, interest, dividends, and other types of income reported on federal and state tax returns.
Deduction Information: This includes deductions claimed on federal and state tax returns, such as deductions for mortgage interest, state and local taxes, and charitable contributions.
Credit Information: This includes tax credits claimed on federal and state tax returns, such as the Earned Income Tax Credit, Child Tax Credit, and education credits.
Withholding Information: This includes information on taxes withheld from wages and other income, as reported on W-2s and 1099s.
Business Income and Expenses: This includes information on business income and expenses reported on federal and state tax returns for businesses, partnerships, and S corporations.
Taxpayer Identification Information: This includes Social Security numbers (SSNs), Individual Taxpayer Identification Numbers (ITINs), and other identifying information used to match tax returns.

2. How The Comparison Process Works

The comparison process between the IRS and state tax agencies involves several steps, from initial data collection to final resolution of discrepancies. Understanding these steps can help taxpayers appreciate the thoroughness of the tax administration system.

2.1 Data Collection And Matching

The first step in the comparison process is the collection of tax return data by both the IRS and state tax agencies. This data is then matched to identify discrepancies and potential issues.

IRS Data Collection: The IRS collects tax return data from various sources, including individual income tax returns (Form 1040), business tax returns (Form 1120, Form 1065), and information returns (W-2s, 1099s). This data is stored in IRS databases and used for comparison purposes.
State Tax Agency Data Collection: State tax agencies collect tax return data from state income tax returns, sales tax returns, and other state tax filings. This data is also stored in state databases and used for comparison purposes.
Data Matching: The IRS and state tax agencies use computer systems to match tax return data based on taxpayer identification information, such as Social Security numbers (SSNs) and names. This matching process helps identify discrepancies between federal and state tax returns.

2.2 Identification Of Discrepancies

Once the data is matched, the IRS and state tax agencies identify discrepancies between federal and state tax returns. These discrepancies can include differences in reported income, deductions, credits, and other tax items.

Types Of Discrepancies: Discrepancies can arise for various reasons, including errors in tax preparation, differences in tax laws between the federal and state levels, and intentional misreporting of income or deductions.
Automated Discrepancy Detection: Tax agencies use automated systems to identify discrepancies based on predefined rules and thresholds. These systems flag returns with significant differences for further review.
Manual Review: In some cases, discrepancies are identified through manual review of tax returns. This may occur when automated systems flag a return for potential issues or when tax examiners notice inconsistencies while reviewing returns.

2.3 Communication Between Agencies

When discrepancies are identified, the IRS and state tax agencies communicate with each other to share information and coordinate their efforts. This communication helps to ensure that discrepancies are resolved efficiently and effectively.

Information Sharing: Tax agencies share information about the discrepancies, including the specific tax items involved, the amounts in question, and any supporting documentation.
Coordination Of Audits: The IRS and state tax agencies may coordinate their audit activities to avoid duplication of effort and ensure that taxpayers are not subjected to multiple audits for the same issues.
Joint Investigations: In cases of suspected tax fraud, the IRS and state tax agencies may conduct joint investigations to gather evidence and pursue enforcement actions.

2.4 Taxpayer Notification And Resolution

If a discrepancy is identified that affects a taxpayer’s tax liability, the taxpayer will be notified by either the IRS or the state tax agency. The notification will explain the discrepancy and provide instructions on how to resolve it.

Notice Of Discrepancy: The notice will typically include a description of the discrepancy, the amount in question, and the tax agency’s proposed adjustment to the taxpayer’s tax liability.
Taxpayer Response: The taxpayer will have an opportunity to respond to the notice and provide documentation to support their position. This may include copies of tax returns, W-2s, 1099s, and other relevant documents.
Resolution Process: The tax agency will review the taxpayer’s response and determine whether the discrepancy can be resolved based on the information provided. If the discrepancy cannot be resolved, the tax agency may conduct an audit or take other enforcement actions.
