Specifications include, but are not limited to: The State is considering issuance of a Request for Proposal (“RFP”) from qualified vendors to provide implementation strategies, expertise, and support in the area of revenue-enhancing initiatives for taxation with respect to increasing compliance and investigating methods to bridge the tax gap. Potential areas and/or processes may include some of the points below: • Enhance the Division of Taxation’s ability to identify non-registrant entities to increase rate of compliance. • Enhance the Division of Taxation’s ability to identify underreporting or nonreporting of taxpayers with respect to taxes administered by the Division to increase rate of compliance – with a focus on determining revenue not reported from emerging and new digital-based income and sales streams. • Enhance capabilities for leveraging existing and/or new datasets through improved methods, including blending of data sets which may lack consistent unique identifiers and determining the correct Federal ID for these records. • Develop analytic models to identify audit leads based on external taxpayer information. • Develop analytic models to identify candidates for audit based on probable underreporting of sales and/or point-of-sale system records leveraging automated auditing processes. • Determine the likely return on investment for various analytic projects based on substantially similar work undertaken in other jurisdictions. • Determine estimated assessments based on underreported income or sales, sourced from third party data. • Determine underreporting in tax filings using credit card data and historical credit/cash ratios by industry. • Determine initiatives to enhance out-of-state proactive collections. • Use pattern recognition algorithms to find anomalies in mass aggregate data to identify potential fraud.
