A W-4 is what you give to your employer so that they can withhold federal income taxes from your wages.

That W-4 is just a form that you fill out for your employer. It only goes to the employer. It tells the employer how much tax to withhold from your pay. They are going to withhold federal tax, maybe state tax (if you live in a state that has state income tax) and they will withhold Social Security and Medicare. The "rest" of the money is what you will receive when you get your paychecks. Sometime in January the employer will issue a document called a W-2 to you. That will show how much you received in your paychecks and how much tax was withheld. That is what you will use to prepare an income tax return. You do not prepare an income tax return until sometime during January to mid-April of 2025. When you receive your W-2, we can provide more help to you if you need it, so you will know how to prepare an income tax return.
