Why does the federal government collect income taxes throughout the year as people earn wages?

The federal government collects income taxes throughout the year to ensure a steady flow of revenue for essential services and programs, such as infrastructure, defense, and social security. This system, known as withholding, helps prevent individuals from facing a large tax bill at the end of the year, making tax payments more manageable. By collecting taxes incrementally, the government can also better manage its budget and maintain fiscal stability.
