Jan 17	Make a payment of your estimated tax for 2005 if you did not pay your income tax for the year through withholding (or did not pay in enough tax that way). Use Form 1040-ES. This is the final installment date for 2005 estimated tax. However, you do not have to make this payment if you file your 2005 return (Form 1040) and pay any tax due by January 31, 2006.
Jan 31	If you did not pay your last installment of estimated tax by January 17, you may choose (but are not required) to file your income tax return (Form 1040) for 2005 by January 31. Filing your return and paying any tax due by January 31 prevents any penalty for late payment of the last installment. If you cannot file and pay your tax by January 31, file and pay your tax by April 17.
Feb 15	If you claimed exemption from income tax withholding last year on the Form W-4 you gave your employer, you must file a new Form W-4 by this date to continue your exemption for another year.

Then, file Form 1040, 1040A, or 1040EZ by October 16.

For more information, see Publication 505.
