Why calculate tax brackets?
Tax brackets help explain why someone does not pay their top rate on every dollar. Think of it like stairs: each step has its own tax rate.
Gross income
This is your starting number before personal deductions. For many W-2 workers, this starts close to annual wages before the standard deduction.
Taxable income
Taxable income is what remains after deductions and adjustments. This is the number that actually runs through the bracket table.
Effective rate
Your effective rate is the average rate after all the bracket layers are added together. This is usually lower than your marginal rate.
What is a tax bracket?
A tax bracket is a range of taxable income taxed at a specific rate. The United States uses a progressive system, so higher income is taxed in layers.
Example: If your marginal rate is 22%, that does not mean all your income is taxed at 22%. It means your last layer of taxable income is inside the 22% bracket.
