Form 4868 (2010) Tax Year Filing Checklist
Purpose and Overview
Form 4868 provides an automatic 6-month extension to file your 2010 calendar-year income tax return, extending the deadline from April 18, 2011, to October 17, 2011. This extension applies to Form 1040, 1040A, 1040EZ, 1040NR, 1040NR-EZ, 1040-PR, or 1040-SS.
Critical Understanding: An extension to the file is not an extension to pay. Any unpaid tax accrues interest from the original due date, and you may face a late payment penalty of 0.5% per month (maximum 25%) on the unpaid balance.
Step-by-Step Filing Process
Step 1: Determine Your Estimated 2010 Tax Liability
Calculate your total estimated tax liability for 2010 using the information available to you. Enter this amount on line 4 of Form 4868. Reference the final tax line from your applicable return form:
- Form 1040: line 60
- Form 1040A: line 37
- Form 1040EZ: line 11
- Form 1040NR: line 59
- Form 1040NR-EZ: line 17
- Form 1040-PR: line 5
- Form 1040-SS: line 5
Make your estimate as accurate as possible. If the IRS later determines your estimate was unreasonable, the extension may be voided.
Step 2: Calculate Total 2010 Payments Made
On line 5, enter all tax payments you have made for 2010 through withholding, estimated tax payments, or other credits. Do not include any payment you are making with Form 4868 itself. Use these reference lines:
- Form 1040: line 72 minus line 68
- Form 1040A: line 44
- Form 1040EZ: line 10
- Form 1040NR: line 68 minus line 63
- Form 1040NR-EZ: line 21
- Form 1040-PR: line 10
- Form 1040-SS: line 10
Step 3: Determine Balance Due
Subtract line 5 from line 4 to calculate your balance due. Enter this amount on line 6. If your payments exceed your liability, enter zero.
Step 4: Decide Payment Amount
On line 7, enter the amount you will pay with this extension request. While you can still receive the extension even if you pay less than the full balance due, paying at least 90% of your actual 2010 tax liability helps you avoid the late payment penalty.
Step 5: Complete Special Status Boxes
Line 8 (Out-of-Country Status): Check this box only if you qualify as being outside the country and require additional time beyond the automatic 2-month extension. You are out of the country if you live and work outside the United States and Puerto Rico, or you are in military or naval service outside those areas.
Understanding the Out-of-Country Extension: Taxpayers abroad automatically receive a 2-month extension to June 15, 2011, without filing Form 4868. If you need more time, file Form 4868 and check line 8 to request an additional 4 months beyond June 15, bringing your total deadline to October 17, 2011.
Line 9 – Nonresident Alien Filers: Check this box only if you are filing Form 1040NR or 1040NR-EZ, did not receive wages subject to U.S. income tax withholding, and your return due date is June 15, 2011.
Step 6: File Form 4868 by Deadline
Submit Form 4868 by April 18, 2011. Taxpayers must file their fiscal year returns by their regular return due date. You can file electronically, pay by credit or debit card, or mail a paper form to the appropriate IRS address.
Step 7: Make Payment if Applicable
If making a payment by check or money order, make it payable to “United States Treasury.” Write your Social Security number, daytime phone number, and “2010 Form 4868” on your payment. Do not staple the payment to the form.
Step 8: Prepare Your Actual Tax Return
Use the extended period to complete your 2010 tax return accurately. The extension gives you until October 17, 2011, to file without facing late filing penalties.
Step 9: Report Extension Payment on Final Return
When filing your 2010 return, include any payment made with Form 4868 on the appropriate line of your tax return. The return instructions will specify how to report this payment.
Step 10: Attach Reasonable Cause Statement if Needed
If you did not pay at least 90% of your actual 2010 tax liability by April 18, 2011, and want to request penalty relief, attach a statement to your completed 2010 return explaining the reasonable cause for late payment. Do not attach this statement to Form 4868.
Understanding Penalties and Interest
Late Payment Penalty
The late payment penalty is 0.5% of the unpaid tax for each month or part of a month that remains unpaid, beginning April 18, 2011. The maximum penalty is 25% of the unpaid tax. This penalty applies even if you receive an extension to file your return.
Avoiding the Late Payment Penalty: You demonstrate reasonable cause and avoid the late payment penalty if you pay at least 90% of your actual 2010 tax liability by April 18, 2011, through withholding, estimated tax payments, or payment with Form 4868.
Late Filing Penalty
If you fail to file Form 4868 by April 18, 2011, and file your return late, you will face a late filing penalty of 5% of the unpaid tax for each month or part of a month your return is late, up to a maximum of 25%.
Minimum Penalty: If your return is more than 60 days late, the minimum penalty is $135 or the balance of tax due on your return, whichever is smaller.
Interest Charges
Interest accrues on any unpaid tax from April 18, 2011, until the tax is paid in full, regardless of whether you receive an extension. Interest compounds daily at the federal short-term rate plus 3%, as specified in IRC section 6621.
Special Considerations
Gift Tax Returns
An extension for your 2010 income tax return automatically extends the time to file Form 709 (Gift Tax Return) for 2010. However, it does not extend the time to pay any gift tax owed. Interest and penalties accrue on unpaid gift tax from the original due date.
Joint Returns and Separate Filings
If you and your spouse each filed separate Forms 4868 but later filed a joint 2010 return, enter the total amount paid with both forms on your joint return. If you file Form 4868 jointly but later file it separately, you and your spouse can divide the payment in any agreed amounts on your separate returns.
Electronic Filing Confirmation
When filing electronically or paying by credit or debit card, you will receive a confirmation number. Keep this number for your records. Do not file a paper Form 4868 if you file electronically unless you are making a payment by check or money order.
Fiscal Year Taxpayers
If you file on a fiscal year basis rather than a calendar year, you must file a paper Form 4868 by the regular due date of your fiscal year return.
Important Reminders
Maximum Extension Period: The total extension period cannot exceed 6 months from the original due date. For taxpayers in the 2010 calendar year, the final extended deadline is October 17, 2011.
No Extension Required for Automatic 2-Month Period: If you are out of the country on April 18, 2011, you automatically receive an extension to June 15, 2011, without filing Form 4868. File the form only if you need time beyond June 15.
Accuracy Requirement: Your estimated tax liability on line 4 must be reasonable based on available information. Unreasonable estimates can void your extension.
Payment Reduces Penalties: Even if you cannot pay the full amount due, paying as much as possible by April 18, 2011, reduces the interest and penalties you will owe.
No Explanation Needed: You do not need to provide a reason for requesting the extension. The IRS will contact you only if your request is denied.
Form Attachment: Do not attach a copy of Form 4868 to your completed 2010 tax return when you file it.
