Each year on April 15th, you file your income taxes. You assemble your W-2 and 1099 documents. You download the forms from the IRS website. You fill out the forms and print them out. If you owe money, you write a check while you print the forms. You mail your documents to the IRS. If you are getting a refund, you wait to receive your refund by check and deposit your refund in your bank account.
