What is the tax refund process in the United States?

When you file your taxes in the United States, the Internal Revenue Service (IRS) will either owe you a refund, or you will owe them money. If you are owed a refund, the IRS will send you a check in the mail (if you filed a paper return) or deposit the money directly into your bank account (if you filed electronically). The IRS issues most refunds within 21 days of receiving your return.

If you owe money to the IRS, you will need to send them a check or money order for the amount you owe, along with a completed form 1040-V, which you can get from the IRS website or your local post office. The IRS will then process your payment and send you a confirmation letter.
