2011 Form W-4, important dates and regulations

The following are a list of dates and regulations accompanying the 2011 Form W-4. (Information taken from IRS Publication 15 - 2011)

By February 15

Request a new Form W-4 from exempt employees. Ask for a new Form W-4, Employee’s Withholding Allowance Certificate, from each employee who claimed exemption from income tax withholding last year.

On February 16

Forms W-4 claiming exemption from withholding expire. Any Form W-4 claiming exemption from withholding for the previous year has now expired. Begin withholding for any employee who previously claimed exemption from withholding but has not given you a new Form W-4 for the current year. If the employee does not give you a new Form W-4, withhold tax based on the last valid Form W-4 you have for the employee that does not claim exemption from withholding or, if one does not exist, as if he or she is single with zero withholding allowances. If the employee furnishes a new Form W-4 claiming exemption from withholding after February15, you may apply the exemption to future wages, but do not refund taxes withheld while the exempt status was not in place.

Before December 1

New Forms W-4. Remind employees to submit a new Form W-4 if their marital status or withholding allowances have changed or will change for the next year.

Using Form W-4 to figure withholding. To know how much federal income tax to withhold from employees’ wages, you should have a Form W-4, Employee’s Withholding Allowance Certificate, on file for each employee. Encourage your employees to file an updated Form W-4 for 2011, especially if they owed taxes or received a large refund when filing their 2010 tax return. Advise your employees to use the Withholding Calculator on the IRS website at www.irs.gov/individuals for help in determining

how many withholding allowances to claim on their Forms W-4.

Ask all new employees to give you a signed Form W-4 when they start work. Make the form effective with the first wage payment. If a new employee does not give you a completed Form W-4, withhold income tax as if he or she is single, with no withholding allowances.

Electronic system to receive Form W-4. You may establish a system to electronically receive Forms W-4 from your employees. See Regulations section 31.3402(f)(5)-1(c) for more information.

Effective date of Form W-4. A Form W-4 remains in effect until the employee gives you a new one. When you receive a new Form W-4 from an employee, do not adjust withholding for pay periods before the effective date of the new form. If an employee gives you a Form W-4 that replaces an existing Form W-4, begin withholding no later than the start of the first payroll period ending on or after the 30th day from the date when you received the replacement Form W-4. For exceptions, see Exemption from federal income tax withholding, IRS review of requested Forms W-4, and Invalid Forms W-4, later.
