State taxes fund state and local government services.
How much you pay:
Federal tax rates are the same for everyone across the country and based on income brackets.
State tax rates vary widely — some states have no income tax at all, while others have progressive or flat tax systems.When tax season rolls around, you’re likely filing two returns — one for the federal government, and one for your state. But what exactly is the difference between federal and state taxes, and why do we pay both?
Let’s break it down.
Why Do We Pay Both Federal and State Taxes?
In the U.S., we live under a system of shared government responsibilities. That means both the federal government and individual state governments collect their own taxes to fund their own services and programs.
Federal taxes pay for national programs like defense, Social Security, Medicare, and infrastructure.
State taxes cover local services like public education, transportation, public safety, and state-level healthcare programs.
Both are essential — they just serve different purposes at different levels of government.
Key Differences Between State and Federal Taxes
Here’s what sets them apart:
Who collects them:
Federal taxes are collected by the IRS (Internal Revenue Service).
State taxes are collected by your state’s revenue agency (like the California Franchise Tax Board or New York State Department of Taxation and Finance).
What they fund:
Federal taxes go toward national-level programs.
Types of taxes:
Federal taxes typically include income tax, payroll tax (for Social Security and Medicare), and sometimes capital gains tax.
State taxes may include income tax, sales tax, property tax, and other local taxes.
What to Expect Each Year
Most taxpayers will:
File a federal tax return with the IRS.
File a state tax return (unless you live in a state with no income tax, like Florida, Texas, or Washington).
See differences in deductions and credits, depending on your state’s rules.
It’s also highly likely that you’ll see different tax refund amounts from each return — that’s because they’re calculated independently from one another.
The Bottom Line
Federal and state taxes may seem like double the hassle, but they each play a vital role in funding the services we all rely on. Understanding the difference helps make tax time a little less confusing, and a little easier to navigate.
