Publication 15
taxmap/pubs/p15-012.htm#en_us_publink1000202414You must notify employees who have no federal income tax withheld
that they may be able to claim a tax refund because of the EIC. Although you do
not have to notify employees who claim exemption from withholding on Form W-4
about the EIC, you are encouraged to notify any employees whose wages for 2010
were less than $43,352 ($48,362 if married filing jointly) that they may be
eligible to claim the credit for 2010. This is because eligible employees may
get a refund of the amount of EIC that is more than the tax they owe.
You will meet this notification requirement if you issue the
employee Form W-2 with the EIC notice on the back of Copy B, or a substitute
Form W-2 with the same statement. You will also meet the requirement by
providing Notice 797, Possible Federal Tax Refund Due to the Earned Income
Credit (EIC), or your own statement that contains the same wording.
If a substitute for Form W-2 is given to the employee on time
but does not have the required statement, you must notify the employee within 1
week of the date the substitute for Form W-2 is given. If Form W-2 is required
but is not given on time, you must give the employee Notice 797 or your written
statement by the date Form W-2 is required to be given. If Form W-2 is not
required, you must notify the employee by February 7, 2011.
