Commercial banks are a fundamental element in the global economy, playing a crucial role in the development and management of financial resources. In addition to their traditional functions of financial intermediation and provision of banking services, these institutions have a significant impact on the fiscal administration of a state. The researched subject of this article is how commercial banking contributes to improving the quality of tax administration. One of the most important contributions of commercial banks to tax administration is the correct collection and reporting of taxes. Banks are required to keep records of their customers' financial transactions, including deposits, withdrawals, transfers and business transactions. Another way commercial banks contribute to tax administration is by facilitating tax payments. Many banks offer tax payment services, allowing taxpayers to easily pay their tax debts to the government. This not only makes the payment process more convenient for taxpayers, but also for tax authorities, as it reduces the risk of late or non-payment of taxes. In conclusion, the commercial bank is an essential piece in the tax administration puzzle. These institutions not only help pay taxpayers but also ensure fairness and transparency in the tax system, which is essential for a country's sustainable economic development.
