A compliance check is a review process the IRS uses to ensure taxpayers accurately report their income, deductions, and credits in accordance with tax laws. Unlike a full audit, which is more detailed and comprehensive, a compliance check is a focused examination that helps the IRS maintain accuracy and fairness in the tax system.
Purpose and Background
The IRS cannot audit every tax return, so it employs compliance checks to efficiently identify returns that may have errors or irregularities. These checks act like spot-checks, helping to confirm whether the information filed matches third-party data such as employer-reported income or other documentation.
How Compliance Checks Work
- Trigger: Compliance checks are typically initiated either through random selection or due to detected discrepancies, such as mismatches between your filed income and third-party reports like W-2s or 1099s.
- IRS Notification: The IRS sends a formal notice requesting additional information or documentation related to specific items on your return.
- Documentation Review: You must respond by providing requested documents such as receipts, invoices, or bank statements to substantiate your claims.
- Resolution: If your response satisfies the IRS, the review concludes with no changes. If discrepancies remain unresolved, the IRS may adjust your tax liability or escalate the matter into a full audit.
Who Can Be Subject to Compliance Checks?
- Individual Taxpayers: Any individual may be selected, often through random processes or when inconsistencies are detected.
- Small Businesses and Self-Employed: Compliance checks frequently focus on verifying business expenses, income reporting, and eligibility for tax credits.
- Large Corporations and Tax Professionals: Compliance checks may review payroll tax compliance, contractor reporting, or specific tax credits.
Practical Example
If you claim itemized deductions for unreimbursed employee expenses but your employer’s W-2 doesn’t reflect related amounts, the IRS might send a compliance check letter requesting receipts. Providing proper documentation typically resolves the inquiry without escalating to a full audit.
Tips for Managing Compliance Checks
- Keep Organised Records: Maintain clear, organized records of income and expenses to substantiate your tax return.
- Respond Promptly: Always reply by the deadline with the requested information to avoid penalties or escalation.
- Seek Professional Help If Needed: Tax professionals can guide you through complex compliance checks and communication with the IRS.
- Never Ignore IRS Notices: Ignoring these notices can result in penalties or a full audit.
Common Misconceptions
- Compliance checks are not necessarily indicators of wrongdoing; they often serve as routine verifications.
- They are different from audits, which are more in-depth and broader in scope.
- Taxpayers have the right to appeal IRS decisions and to seek assistance from the Taxpayer Advocate Service if needed.
