You can have the IRS figure your tax on Form 1040EZ, Form 1040A, or Form 1040 if you file your return by April 18, 2011.

If you paid too much, we will send you a refund. If you did not pay enough, we will send you a bill for the balance. To avoid interest or the penalty for late payment, you must pay the bill within 30 days of the date of the bill or by the due date for your return, whichever is later.

The IRS will also figure the credit for the elderly or the disabled and the earned income credit for you.

The IRS cannot figure your tax if any of the following apply.

1. You want your refund to be directly deposited in your accounts.
2. You want any part of your refund applied to your 2011 estimated tax.
3. You had income for the year from sources other than wages, salaries, tips, interest, dividends, taxable social security benefits, unemployment compensation, IRA distributions, pensions, and annuities.
4. Your taxable income is $100,000 or more.
5. You itemize deductions.

To have the IRS figure your tax, follow these steps if you are filing Form 1040EZ.

Print or type your name and address in the spaces provided.

Enter your social security number in the space provided. If you are married, enter the social security numbers of you and your spouse.

Read lines 1 through 9b and complete the lines that apply to you. Do not complete lines 10 through 13. If you are filing a joint return, use the space to the left of line 6 to separately show your taxable income and your spouse's taxable income.

Enter any federal income tax withheld on line 7. Federal income tax withheld is shown on Form W-2, box 2 or Form 1099, box 4.

If you can take the earned income credit, the IRS will figure it for you. Enter "EIC" in the space to the left of line 9a. Enter the nontaxable combat pay you elect to include in earned income on line 9b.

Attach a copy of each of your Forms W-2 to your return.

If you want to allow a friend, family member, or any other person you choose to discuss your 2010 tax return with the IRS, check the "Yes" box in the "Third party designee" area on your return. Also, enter the designee's name, phone number, and any five digits the designee chooses as his or her personal identification number (PIN). If you check the "Yes" box, you, and your spouse if filing a joint return, are authorizing the IRS to call the designee to answer any questions that may arise during the processing of your return.

Sign and date your return and enter your occupation(s). If you are filing a joint return, both you and your spouse must sign it. Enter your daytime phone number in the space provided. This may help speed the processing of your return if we have a question that can be answered over the phone. If you are filing a joint return, you may enter either your or your spouse's daytime phone number.

Mail your return to the Internal Revenue Service Center for the area where you live. A list of Service Center addresses is shown in the Instructions for Form 1040EZ in the back.
