Does the IRS set tax rates?

No. The IRS interprets, implements, and enforces the tax laws and rates that are adopted by the U.S. Congress and signed by the President. As part of the implementation of tax law, the IRS publishes the annual rate schedule listing the tax rate for each income bracket.

What is "Where's my refund?"

"Where's my refund?" is an online tool offered by the IRS that allows taxpayers to check the status of their tax refund. In order to use the tool, a taxpayer must enter their Social Security number, filing status, and the exact amount of the refund as shown on the tax return.

What should I do if I made a mistake on my tax filing?

It depends on the type of mistake. IRS employees can correct mathematical mistakes without the need to file an amended return. Mistakes in filing status, deductions, income, or credits require an amended return. The amended return should be filed using Form 1040X.
