Download IRS Form 433-D from the Internal Revenue Service website or call (800) TAX-FORM to receive a copy.
Fill in your name, spouse's name (if applicable), address, Social Security number, spouse's Social Security number and two telephone numbers at which you can be reached easily. Check the box if you wish to submit a new W-4 form with this agreement as changing your withholdings on a W-4 can prevent you from owing such a large tax bill next year. Provide the name, address and phone number of your employer as well as the name and address of your financial institution.
Supply the form numbers to indicate the kinds of taxes you owe. Indicate the tax periods for which the installment agreement is to be made and the total amount owed to the IRS. Indicate the initial payment amount you're enclosing with Form 433-D, and list the amount you intend to pay per month thereafter, making sure to include a recurring day of each month the IRS can expect future payments. If you plan to increase or decrease the amount you pay on a future date, note this in the box below your installment proposal.
Initial the box to indicate you understand the terms of the installment agreement. If you choose to make payments by direct debit from your checking or savings account, enter your routing number and account number. Attach a voided check to the installment agreement. You and your spouse should sign and date the form and provide your titles.
File Form 433-D with the IRS along with your 1040, 1040EZ or 1040A form. Check the IRS official website for specific instructions regarding the mailing address to which you should send Form 433-D as it varies by region.
