Farmers and crew leaders must withhold federal income tax from the wages of farmworkers if the wages are subject to social security and Medicare taxes. The amount to withhold is figured on gross wages before taking out social security and Medicare taxes, union dues, insurance, etc. You may use one of several methods to determine the amount of federal income tax withholding. They are discussed in Publication 15-T.taxmap/pubs/p51-004.htm#en_us_publink100070978
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 2009, especially if they owed taxes or received a large refund when filing their 2008 tax return. Advise your employees to visit the IRS website at www.irs.gov/individuals
and select the "IRS Withholding Calculator" link for help in determining how many withholding allowances to claim on their Form W-4. Ask each new employee to give you a signed Form W-4 when starting work. Make the form effective with the first wage payment. If a new employee does not give you a completed Form W-4, withhold tax as if he or she is single, with no withholding allowances.
You can provide Formulario W-4(SP), Certificado de Exención de Retenciones del Empleado, in place of Form W-4, Employee's Withholding Allowance Certificate, to your Spanish-speaking employees. For more information, see Publicación 17(SP), El Impuesto Federal sobre los Ingresos (Para Personas Físicas).taxmap/pubs/p51-004.htm#en_us_publink100070980
A Form W-4 remains in effect until the employee gives you a new one. When you receive a new Form W-4, do not adjust withholding for pay periods before the effective date of the new form. Do not adjust withholding retroactively. For exceptions, see Exemption from federal income tax withholding
, IRS review of requested Forms W-4
, and Invalid Forms W-4
later. If an employee gives you a replacement 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.
A Form W-4 that makes a change for the next calendar year will not take effect in the current calendar year.
The amount of federal income tax withholding is based on marital status and withholding allowances. Your employees may not base their withholding amounts on a fixed dollar amount or percentage. However, the employee may specify a dollar amount to be withheld in addition to the amount of withholding based on filing status and withholding allowances claimed on Form W-4.
Employees may claim fewer withholding allowances than they are entitled to claim. They may do this to ensure that they have enough withholding or to offset other sources of taxable income that are not subject to withholding.
Publication 505, Tax Withholding and Estimated Tax, contains detailed instructions for completing Form W-4. Along with Form W-4, you may wish to order
Publication 505 and Publication 919, How Do I Adjust My Tax Withholding, for your employees.
Do not accept any withholding or estimated tax payments from your employees in addition to withholding based on their Form W-4. If an employee wants additional withholding, he or she should submit a new Form W-4 and, if necessary, pay estimated tax by filing Form 1040-ES, Estimated Tax for Individuals.taxmap/pubs/p51-004.htm#en_us_publink100070983
Generally, an employee may claim exemption from federal income tax withholding because he or she had no federal income tax liability last year and expects none this year. See the Form W-4 instructions for more information. However, the wages are still subject to social security and Medicare taxes.
A Form W-4 claiming exemption from withholding is valid for only one calendar year. To continue to be exempt from withholding in the next year, an employee must give you a new Form W-4 by February 15 of that year. If the employee does not give you a new Form W-4, withhold tax as if the employee is single with zero withholding allowances or withhold based on the last valid Form W-4 you have for the employee.taxmap/pubs/p51-004.htm#en_us_publink100070984
In general, you must withhold federal income taxes on the wages of nonresident alien employees. However, see Publication 515 for exceptions to this general rule.
Under this procedure, you add an amount, as set forth in the chart below, to the nonresident alien employee's wages solely for purposes of calculating the federal income tax withholding for each payroll period. You determine the amount to be withheld by applying the federal income tax withholding tables to the amount of wages paid plus the additional chart amount.
Nonresident alien students from India and business apprentices from India are not subject to this procedure.
The amount to be added to the nonresident alien employee's wages to calculate federal income tax withholding is set forth in the following chart:
Amount to Add to Nonresident Alien Employee's Wages for Calculating Income Tax Withholding Only
| ||Payroll Period||Add Additional|| |
| ||Weekly||$ 138.00|| |
| ||Biweekly||276.00|| |
| ||Semimonthly||299.00|| |
| ||Monthly||598.00|| |
| ||Quarterly||1,795.00|| |
| ||Semiannually||3,590.00|| |
| ||Annually||7,180.00|| |
| ||Daily or Miscellaneous|
(each day of the payroll period)
The amounts added under this chart for purposes of this procedure are added to wages solely for the purpose of calculating the amount of federal income tax withholding on the wages of the nonresident alien employee. These chart amounts should not be included in any box on the employee's Form W-2 and do not increase the federal income tax liability of the employee. Also, these chart amounts do not increase the social security, Medicare, or FUTA tax liability of the employer or the employee.
This procedure only applies to nonresident alien employees who have wages subject to federal income tax withholding.taxmap/pubs/p51-004.htm#en_us_publink100070986
An employer using the percentage method of withholding pays wages of $500 for a biweekly payroll period to a married nonresident alien employee. The nonresident alien has properly completed Form W-4, entering marital status as "single" with one withholding allowance and indicating status as a nonresident alien on line 6 of Form W-4 (see Nonresident alien employee's Form W-4
later). The employer determines the wages to be used in the withholding tables by adding to the $500 amount of wages paid the amount of $276 from the chart earlier ($776 total). The employer then applies the applicable table (Table 2(a), the table for biweekly payroll period, single persons) by subtracting the applicable percentage method amount for one withholding allowance for a biweekly payroll period from $776 and making the calculations under the table.
The $276 added to wages for calculating income tax withholding is not reported on Form W-2, and does not affect the social security tax, Medicare tax, or FUTA tax liability of the employer or the employee.taxmap/pubs/p51-004.htm#en_us_publink100070987
This procedure for determining the amount of federal income tax withholding does not apply to a supplemental wage payment (see Supplemental wages
on page 13) if the 35% mandatory flat rate withholding applies or if the 25% flat rate withholding is being used to calculate income tax withholding on the supplemental wage payment.
When completing Forms W-4, nonresident aliens are required to:
- Not claim exemption from income tax withholding;
- Request withholding as if they are single, regardless of their actual marital status;
- Claim only one allowance (if the nonresident alien is a resident of Canada, Mexico, or Korea, he or she may claim more than one allowance); and
- Write "Nonresident Alien" or "NRA" above the dotted line on line 6 of Form W-4.
If you maintain an electronic Form W-4 system, you should provide a field for nonresident alien employees to enter nonresident alien status in lieu of writing "Nonresident Alien" or "NRA" above the dotted line on line 6.
Nonresident alien employees are no longer required to request additional withholding in the box for line 6 on Form W-4. However, a nonresident alien employee may request additional withholding at his or her option.
If a nonresident alien employee claims a tax treaty exemption from withholding, the employee must submit Form 8233, Exemption from Withholding on Compensation for Independent (and Certain Dependent) Personal Services of a Nonresident Alien Individual, with respect to the income exempt under the treaty, instead of Form W-4. See Publication 515 for details.taxmap/pubs/p51-004.htm#en_us_publink100070991
In the past, you had to routinely send the IRS any Form W-4 claiming complete exemption from withholding if $200 or more in weekly wages was expected or claiming more than 10 allowances. Employers no longer have to submit these Forms W-4 to the IRS. However, Forms W-4 are still subject to review. When we refer to Form W-4, the same rules apply to Formulario W-4(SP), its Spanish translation.
You may receive a notice from the IRS requiring you to submit copies of Forms W-4. Send the requested copy or copies of Form W-4 to the IRS at the address provided and in the manner directed by the notice. You may also be directed to make available for inspection by an IRS employee certain Forms W-4. The notice you receive from the IRS may relate to one or more of your named employees. IRS may also require you to submit copies of Form W-4 to the IRS as directed by a revenue procedure or notice published in the Internal Revenue Bulletin.
After submitting a copy of the requested Form W-4 to the IRS, continue to withhold federal income tax based on that Form W-4 if it is valid (see Invalid Forms W-4
later). However, the IRS may later notify you in writing that the employee is not entitled to claim a complete exemption from withholding or more than the maximum number of withholding allowances specified by the IRS in the written notice. The notice will also specify the applicable marital status for purposes of calculating the required amount of withholding. You are to withhold federal income tax based on the effective date shown on the notice using the maximum number of withholding allowances and marital status specified in the notice (commonly referred to as a "lock-in letter").
The IRS uses information reported on Form W-2, Wage and Tax Statement, to identify employees with withholding compliance problems. In some cases, where a serious under-withholding problem is found to exist for a particular employee, the IRS may issue a lock-in letter to the employer specifying the maximum number of withholding allowances and marital status permitted for a specific employee. If the employee is employed by you as of the date of the notice, you must furnish the notice to the employee within 10 business days of receipt. You may follow any reasonable business practice to furnish the copy of the notice to the employee.taxmap/pubs/p51-004.htm#en_us_publink100070993
When you receive the notice specifying the maximum number of withholding allowances and marital status permitted, you may not withhold immediately on the basis of the notice. You must begin withholding tax on the basis of the notice for any wages paid after the date specified in the notice. The delay between your receipt of the notice and the date to begin the withholding on the basis of the notice permits the employee to contact the IRS.taxmap/pubs/p51-004.htm#en_us_publink100070994
If you receive a notice for an employee who is not currently performing services for you, you are still required to furnish the notice to the employee and withhold based on the notice if:
- You are paying wages for the employee's prior services and the wages are subject to income tax withholding on or after the date specified in the notice.
- You reasonably expect the employee to resume services within 12 months of the date of the notice.
- The employee is on a bona fide leave of absence that does not exceed 12 months or the employee has a right to reemployment after the leave of absence.
If you are required to furnish and withhold based on the notice and the employment relationship is terminated after the date of the notice, you must continue to withhold based on the notice if you continue to pay any wages subject to income tax withholding. You must also withhold based on the notice or modification notice (see Modification notice
next) if the employee resumes the employment relationship with you within 12 months after the termination of the employment relationship.
After issuing the notice specifying the maximum number of withholding allowances and marital status permitted, the IRS may issue a subsequent notice (modification notice) that modifies the original notice. The modification notice may change the marital status and/or the number of withholding allowances permitted. You must withhold federal income tax based on effective date specified in the modification notice.taxmap/pubs/p51-004.htm#en_us_publink100070997
After the IRS issues a notice or modification notice, if the employee provides you with a new Form W-4 claiming complete exemption from withholding or claims a marital status, a number of withholding allowances, and any additional withholding that results in less withholding than would result under the IRS notice or modification notice, you must disregard the new Form W-4. You are required to withhold on the basis of the notice or modification notice unless the IRS subsequently notifies you to withhold based on the new Form W-4. If the employee wants to put a new Form W-4 into effect that results in less withholding than required, the employee must contact the IRS.
If, after you receive an IRS notice or modification notice, your employee provides you with a new Form W-4 that does not claim exemption from federal income tax withholding and claims a marital status, a number of withholding allowances, and any additional withholding that results in more withholding than would result under the notice or modification notice, you must withhold tax on the basis of that new Form W-4. Otherwise, disregard any subsequent Forms W-4 provided by the employee and withhold based on the IRS notice or modification notice.taxmap/pubs/p51-004.htm#en_us_publink100070998
You are encouraged to have your employees use the official version of Form W-4 to claim withholding allowances or exemption from withholding. Call the IRS at 1-800-829-3676 or visit the IRS website at www.irs.gov
to obtain copies of Form W-4.
You may use a substitute version of Form W-4 to meet your business needs. However, your substitute Form W-4 must contain language that is identical to the official Form W-4 and your form must meet all current IRS rules for substitute forms. At the time that you provide your substitute form to the employee, you must provide him or her with all tables, instructions, and worksheets from the current Form W-4.
You are prohibited from accepting a substitute Form W-4 developed by an employee, and the employee submitting such form will be treated as failing to furnish a Form W-4. However, continue to use any valid Forms W-4 developed by your employees that you accepted before October 11, 2007. taxmap/pubs/p51-004.htm#en_us_publink100070999
Any unauthorized change or addition to Form W-4 makes it invalid. This includes taking out any language by which the employee certifies that the form is correct. A Form W-4 is also invalid if, by the date an employee gives it to you, he or she indicates in any way that it is false. An employee who submits a false Form W-4 may be subject to a $500 penalty. You may treat a Form W-4 as invalid if the employee wrote "exempt" on line 7 and also entered a number on line 5 or an amount on line 6.
When you get an invalid Form W-4, do not use it to figure federal income tax withholding. Tell the employee that it is invalid and ask for another one. If the employee does not give you a valid one, withhold taxes as if the employee was single and claiming no withholding allowances. However, if you have an earlier Form W-4 for this worker that is valid, withhold as you did before. taxmap/pubs/p51-004.htm#en_us_publink100071000
If you receive a Notice of Levy on Wages, Salary, and Other Income (Forms 668-W(c), 668-W(c)(DO), or 668-W(ICS)), you must withhold amounts as described in the instructions for these forms. Publication 1494 (2009), Table for Figuring Amount Exempt From Levy on Wages, Salary, and Other Income—Forms 668-W(c), 668-W(c)(DO), and 668-W(ICS), shows the exempt amount. If a levy issued in a prior year is still in effect and the taxpayer submits a new Statement of Exemptions and Filing Status, use the current year Publication 1494 to compute the exempt amount.taxmap/pubs/p51-004.htm#en_us_publink100071001
There are several ways to figure federal income tax withholding.
- Wage bracket tables. See page 3 of Publication 15-T for directions on how to use the tables.
- Percentage method. See page 3 of Publication 15-T for directions on how to use the percentage method.
- Formula tables for percentage method withholding. See Publication 15-T.
- Wage bracket percentage method withholding tables. See Publication 15-T.
- Other alternative methods. See Publication 15-T.
Employers with automated payroll systems will find the two alternative formula tables and the two alternative wage bracket percentage method tables in Publication 15-T useful.
If an employee wants additional federal tax withheld, have the employee show the extra amount on Form W-4.taxmap/pubs/p51-004.htm#en_us_publink100071002
Supplemental wages are compensation paid to an employee in addition to the employee's regular wages. They include, but are not limited to, bonuses, commissions, overtime pay, accumulated sick leave, severance pay, awards, prizes, back pay and retroactive pay increases for current employees, and payments for nondeductible moving expenses. Other payments subject to the supplemental wage rules include taxable fringe benefits and expense allowances paid under a nonaccountable plan.
If you pay supplemental wages with regular wages but do not specify the amount of each, withhold federal income tax as if the total was a single payment for a regular payroll period.
If you pay supplemental wages separately (or combine them in a single payment and specify the amount of each), the federal income tax withholding method depends partly on whether you withhold federal income tax from your employee's regular wages.
- If you withheld federal income tax from an employee's regular wages in the current or immediately preceding calendar year, you can use one of the following methods for the supplemental wages.
- Withhold a flat 25% (no other percentage allowed).
- Add the supplemental wages to the concurrently paid regular wages, or, if there are no concurrently paid wages, to the most recent payment of regular wages this year. Then figure the federal income tax withholding as if the total was a single payment. Subtract the tax already withheld from the regular wages. Withhold the remaining tax from the supplemental wages. If there are no concurrently paid regular wages but there were other payments of supplemental wages (after the last payment of regular wages but before the current payment of supplemental wages), aggregate all the payments, calculate the tax on the total, subtract the tax already withheld from the regular wages and the previous supplemental wages, and withhold the remaining tax.
- If you did not withhold federal income tax from the employee's regular wages in the current or immediately preceding calendar year, use method 1-b above. This would occur, for example, when the value of the employee's withholding allowances claimed on Form W-4 is more than the wages.
Separate rules apply to any supplemental wages exceeding $1,000,000 that you pay to an individual during the year. See section 7 in
Publication 15 (Circular E) for details.
Regardless of the method that you use to withhold federal income tax on supplemental wages, they are generally subject to social security, Medicare, and FUTA taxes.
