Tax and revenue gaps demand additional sources of revenue to fund central government operations. New revenue can be found with a higher success rate in collecting tax revenue from delinquent taxpayers, unregistered businesses, non-filers and under-reporters. D&B can help improve tax compliance and revenue collections. D&B information can be integrated into central revenue systems to identify delinquent businesses early in the collection process, eliminate duplicates in tax databases, and provide a single view of a taxpayer to prioritise collection based upon ability to pay.
