The IRS Has Changed the TIN Matching Process: A Quick Recap

Do you remember when, in September 2013, TIN Matching went through a re-engineering process moving to a new platform and enhanced some features? During this last upgrade, one of the enhancements involved moving to a proximal search match for both employer identification numbers (EIN) and social security numbers (SSN). However, recently, after meeting with the Information Reporting Program Advisory Committee (IRPAC) and other external users, the IRS learned there are discrepancies between TIN Matching results when compared to CP2100 notices for EINs only. Now, as of Monday, November 2, 2015, TIN Matching will be updated to change from proximal match to an exact match for EIN only. For more information, feel free to reach out and contact our experts at Sovos Compliance. We can also help you with real-time and bulk TIN matching.
