What is the benefit of having state and local taxes on income instead of collecting all such taxes at the federal level?

State and local taxes offer increased autonomy and flexibility for individual states and localities. Each state and local government can set its own tax rates, regulations, and policies. This allows them to experiment with different policies and tools that work best for their specific circumstances and objectives, which could result in more effective tax systems and improved public services. #Part 3: Responsiveness to local needs

Having separate state and local taxes can create competition among jurisdictions, which can encourage them to improve their tax systems and provide better public services. In order to attract residents and businesses, states and localities must offer competitive tax rates and efficient public services, which can lead to overall improvements in the quality of government activities, resource allocation, and service delivery. In conclusion, the benefit of having state and local taxes on income instead of collecting all such taxes at the federal level lies in the increased decentralization, autonomy, flexibility, and responsiveness to local needs that come with separate tax systems for different regions. This system allows states and local governments to better address their citizens' needs and preferences, tailor their budgets more efficiently, and foster competition among jurisdictions, leading to improved services and overall living conditions.
