Individuals – Make a payment of your estimated tax for 2013 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.

Employers – Nonpayroll Withholding. If the monthly deposit rule applies, deposit the tax for payments in December 2013.

If you do not pay your estimated tax by January 15, you must file your 2013 return and pay any tax due by March 3, 2014, to avoid an estimated tax penalty.
January 31
Employers – Give your employees their copies of Form W-2 for 2013 by January 31, 2014. If an employee agreed to receive Form W-2 electronically, post it on a website accessible to the employee and notify the employee of the posting by January 31.
Businesses – Give annual information statements to recipients of 1099 payments made during 2013.
Employers – Federal unemployment tax. File Form 940 for 2013. If your undeposited tax is $500 or less, you can either pay it with your return or deposit it. If it is more than $500, you must deposit it. However, if you already deposited the tax for the year in full and on time, you have until February 11 to file the return.
Employers – Social Security, Medicare, and withheld income tax. File Form 941 for the fourth quarter of 2013. Deposit any undeposited tax. (If your tax liability is less than $2,500, you can pay it in full with a timely filed return.) If you deposited the tax for the quarter in full and on time, you have until February 10 to file the return.
Employers – Nonpayroll taxes. File Form 945 to report income tax withheld for 2013 on all nonpayroll items, including backup withholding and withholding on pensions, annuities, IRAs, gambling winnings, and payments of Indian gaming profits to tribal members. Deposit any undeposited tax. (If your tax liability is less than $2,500, you can pay it in full with a timely filed return.) If you deposited the tax for the year in full and on time, you have until February 10 to file the return.
Individuals – who must make estimated tax payments. If you did not pay your last installment of estimated tax by January 15, you may choose (but are not required) to file your income tax return (Form 1040) for 2013. Filing your return and paying any tax due by January 31 prevents any penalty for late payment of last installment.
