Background
25.29.1.1.1 (08-18-2021) Background The One Tax Compliance initiative was developed to ensure consistency in performing tax compliance checks for individuals when making suitability determinations for hiring or monitoring tax compliance. To provide uniformity, suitability and monitoring tax compliance checks transitioned to use the enterprise Tax Compliance Check Service (TCCS), replacing various legacy tools and reducing the need for manual account research. The TCCS is an enterprise common service developed to perform automated suitability and monitoring tax checks across the IRS. The TCCS uses automated business rules to lookup taxpayer accounts and identify the tax compliance status. This IRM outlines the criteria used and the results obtained through the automated TCCS service, in performing a tax compliance check for suitability and monitoring. To be fully compliant with federal tax filing and payment obligations, an individual must accurately and timely file, pay on time and have no outstanding tax liability.

In compliance with IRM 1.11.2, Internal Revenue Manual (IRM) Process, this IRM will be reviewed annually to determine if revisions are needed.

Standard Tax Compliance Checks - Overview
25.29.1.2 (08-18-2021) Standard Tax Compliance Checks - Overview The TCCS standardizes the tax compliance criteria and the tax compliance results used for tax compliance checks performed by the IRS for the purpose of suitability and monitoring. The use of the enterprise TCCS application to perform suitability and monitoring tax checks ensures uniformity across the IRS. Business units will use the results to make suitability and/or compliance monitoring decisions based on the specific business process. To be fully compliant with federal tax filing and payment obligations, an individual must accurately and timely file, pay on time, and have no outstanding tax liability. TCCS will review four years of tax records or up to five years if a Fraudulent Failure to File or Civil Tax Fraud penalty was assessed.
Tax Compliance Result
25.29.1.3 (11-24-2023) Tax Compliance Result The automated tax check and TCCS will return an overall tax compliance result and a sectional result for each of the three-criterion (filing, outstanding liabilities, and timeliness of payments). To be fully compliant with federal tax filing and payment obligations, an individual must accurately and timely file, pay on time, and have no outstanding tax liability. TCCS uses three outcomes to measure tax compliance: compliant, non-compliant, or compliance Issue. The overall tax compliance result is based upon the sectional result for each criterion (filing, accuracy, outstanding liabilities, and timeliness). The overall tax compliance result is always reflective of the lowest level of tax compliance identified within each of the sectional results. For example, if tax records indicate that a taxpayer is compliant related to filing, non-compliant related to outstanding liabilities, and has a compliance issue related to prior late payments, the overall tax compliance result would be non-compliant since this reflects the lowest level of compliance amongst the sectional results.
