The Electronic Wallet project provides a tool to make transparent the information on available balances in favor of taxpayers, through the website of the General Treasury of the Republic (TGR). Likewise, make available tools on the TGR intranet, to support the institution’s officials, in order to provide better care.

In the first place, the concept of electronic wallet, arises from the accumulation of balances in favor that taxpayers may have due to procedures carried out, and that, probably, as a result of being insignificant values, they are unaware of their existence.

In addition, the objective was defined, to allow the taxpayer to make requests for the return of these surpluses through the treasury’s website, or to use these available funds for the payment of debts that are pending in their single tax account.

Meanwhile, for the functionality of returning surpluses collected in the Electronic Wallet, these can be managed for withdrawal through a deposit in the taxpayer’s current bank account, or through a check issued in the name of the taxpayer. This decision is made by the taxpayer, and according to the choice made, the system presents the bank details that the TGR has in its databases, and giving the option to update them, if necessary.

Finally, the application has charts of movements and details of the balances of the monies that make up the Electronic Wallet.
