When you prepare your tax return, you download multiple forms the IRS web site. You fill out the forms, double-check your work, and then print them out. If you owe money, you write a check. You mail your tax return along with the check if you owe money. If you are getting a refund, you wait to receive your refund by check and deposit your refund in your bank account.
