What is Income Tax

Income tax is the tax you pay on money you earn. This includes wages, freelance income, and sometimes investment earnings. In the U.S., income tax depends on how much you earn during the year. Higher income is taxed at higher rates, but only in portions, not all at once.

What is Taxable Income

Taxable income is the part of your income that is used to calculate your tax. It may be lower than your total income because deductions can reduce it. For example, if you earn $50,000 and qualify for $10,000 in deductions, you may only be taxed on $40,000.

What are Tax Deductions

Deductions reduce the amount of income that is taxed. They don’t directly cut your tax bill but can still lower it by reducing taxable income. Common examples include certain business expenses, student loan interest, or mortgage interest. You can choose a standard deduction or itemize, depending on your situation.

What are Tax Credits

Tax credits directly reduce the amount of tax you owe. For example, if you owe $1,500 and have a $500 credit, you only pay $1,000. Some credits can even give you a refund if they reduce your tax below zero.
