(Supplement to Publication 15 (Circular E), Employer's Tax Guide)

Future Developments(p1)

For the latest information about developments related to Publication 15-A, such as legislation enacted after it was published, go to

What's New(p1)

New Form 8922 replaces the "Third-Party Sick Pay Recap" Form W-2.(p1)
New Form 8922 replaces the "Third-Party Sick Pay Recap" previously done on Form W-2, Wage and Tax Statement. For wages paid in 2014, new Form 8922, Third-Party Sick Pay Recap, is used to reconcile employment tax returns (for example, Form 941) with Forms W-2 when third-party sick pay is paid. Third party payers of sick pay (and in certain cases, employers) file Form 8922 with the IRS instead of filing a "Third-Party Sick Pay Recap" Form W-2 and "Third-Party Sick Pay Recap" Form W-3, Transmittal of Wage and Tax Statements, with the Social Security Administration (SSA). For more information, see Form 8922, Third-Party Sick Pay Recap in section 6.
COBRA premium assistance credit. (p2)
Effective for tax periods beginning after December 31, 2013, the credit for COBRA premium assistance payments cannot be claimed on Form 941, Employer's QUARTERLY Federal Tax Return (or Form 944, Employer's ANNUAL Federal Tax Return). Instead, after filing your Form 941 (or Form 944), file Form 941-X, Adjusted Employer's QUARTERLY Federal Tax Return or Claim for Refund (or Form 944-X, Adjusted Employer's ANNUAL Federal Tax Return or Claim for Refund) to claim the COBRA premium assistance credit. Filing a Form 941-X (or Form 944-X) before filing a Form 941 (or Form 944) for the return period may result in errors or delays in processing your Form 941-X (or Form 944-X). For more information, see the Instructions for Form 941 (or the Instructions for Form 944) or visit and enter "COBRA" in the search box.
Social security and Medicare tax for 2015.(p2)
The social security tax rate is 6.2% each for the employee and employer, unchanged from 2014. The social security wage base limit is $118,500.
The Medicare tax rate is 1.45% each for the employee and employer, unchanged from 2014. There is no wage base limit for Medicare tax.
Social security and Medicare taxes apply to the wages of household workers you pay $1,900 or more in cash or an equivalent form of compensation. Social security and Medicare taxes apply to election workers who are paid $1,600 or more in cash or an equivalent form of compensation.
2015 withholdng tables.(p2)
This publication includes the 2015 Formula Tables for Percentage Method Withholding; Wage Bracket Percentage Method Tables; Combined Federal Income Tax, Employee Social Security Tax, and Employee Medicare Tax Withholding Tables; and Tables for Withholding on Distributions of Indian Gaming Profits to Tribal Members.
Withholding allowance.(p2)
The 2015 amount for one withholding allowance on an annual basis is $4,000.
Leave-based donation programs to aid victims of the Ebola Virus Disease (EVD) outbreak in Guinea, Liberia, and Sierra Leone.(p2)
Under these programs, employees may donate their vacation, sick, or personal leave in exchange for employer cash payments made before January 1, 2016, to qualified tax-exempt organizations providing relief for the victims of the EVD outbreak in Guinea, Liberia, and Sierra Leone. The donated leave will not be included in the income or wages of the employee. The employer may deduct the cash payments as business expenses or charitable contributions. For more information, see Notice 2014-68, 2014-47 I.R.B. 842, available at
Work opportunity tax credit for qualified tax-exempt organizations hiring qualified veterans extended.(p2)
The work opportunity tax credit is now available for eligible unemployed veterans who began work after December 31, 2013, and before January 1, 2015. Qualified tax-exempt organizations that hire eligible unemployed veterans can claim the work opportunity tax credit against their payroll tax liability using Form 5884-C, Work Opportunity Credit for Qualified Tax-Exempt Organizations Hiring Qualified Veterans. For more information, visit and enter "work opportunity tax credit" in the search box.


No federal income tax withholding on disability payments for injuries incurred as a direct result of a terrorist attack directed against the United States.(p2)
Disability payments (including Social Security Disability Insurance (SSDI) payments) for injuries incurred as a direct result of a terrorist attack directed against the United States (or its allies) are not included in income. Because federal income tax withholding is only required when a payment is includable in income, no federal income tax should be withheld from these payments.
Same-sex marriage.(p2)
For federal tax purposes, individuals of the same sex are considered married if they were lawfully married in a state (or foreign country) whose laws authorize the marriage of two individuals of the same sex, even if the state (or foreign country) in which they now live does not recognize same-sex marriage. For more information, see Revenue Ruling 2013-17, 2013-38 I.R.B. 201, available at
Notice 2013-61 provides special administrative procedures for employers to make claims for refunds or adjustments of overpayments of social security and Medicare taxes with respect to certain same-sex spouse benefits before expiration of the period of limitations. Notice 2013-61, 2013-44 I.R.B. 432, is available at
Additional Medicare Tax withholding.(p2)
In addition to withholding Medicare tax at 1.45%, you must withhold a 0.9% Additional Medicare Tax from wages you pay to an employee in excess of $200,000 in a calendar year. You are required to begin withholding Additional Medicare Tax in the pay period in which you pay wages in excess of $200,000 to an employee and continue to withhold it each pay period until the end of the calendar year. Additional Medicare Tax is only imposed on the employee. There is no employer share of Additional Medicare Tax. All wages that are subject to Medicare tax are subject to Additional Medicare Tax withholding if paid in excess of the $200,000 withholding threshold.
For more information on what wages are subject to Medicare tax, see the chart, Special Rules for Various Types of Services and Payments, in section 15 of Publication 15 (Circular E), Employer's Tax Guide. For more information on Additional Medicare Tax, visit and enter "Additional Medicare Tax" in the search box.
Outsourcing payroll tax duties.(p2)
Employers are responsible to ensure that tax returns are filed and deposits and payments are made, even if the employer contracts with a third party to perform these acts. The employer remains responsible if the third party fails to perform any required action. If you choose to outsource any of your payroll and related tax duties (that is, withholding, reporting, and paying over social security, Medicare, FUTA, and income taxes) to a third-party payer, such as a payroll service provider (PSP) or reporting agent, visit and enter "outsourcing payroll duties" in the search box for helpful information on this topic. For more information see Agent With an Approved Form 2678 and Reporting Agents in section 7.
Federal tax deposits must be made by electronic funds transfer (EFT).(p3)
You must use EFT to make all federal tax deposits. Generally, an EFT is made using the Electronic Federal Tax Payment System (EFTPS). If you do not want to use EFTPS, you can arrange for your tax professional, financial institution, payroll service, or other trusted third party to make electronic deposits on your behalf. Also, you may arrange for your financial institution to initiate a same-day wire payment on your behalf. EFTPS is a free service provided by the Department of Treasury. Services provided by your tax professional, financial institution, payroll service, or other third party may have a fee.
For more information on making federal tax deposits, see How To Deposit in Publication 15 (Circular E). To get more information about EFTPS or to enroll in EFTPS, visit or call 1-800-555-4477 or 1-800-733-4829 (TDD). Additional information about EFTPS is also available in Publication 966, Electronic Federal Tax Payment System: A Guide To Getting Started.
You must receive written notice from the IRS to file Form 944.(p3)
If you have been filing Forms 941 (or Forms 941-SS, Employer's QUARTERLY Federal Tax Return—American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands, or Formularios 941-PR, Planilla para la Declaración Federal TRIMESTRAL del Patrono), and believe your employment taxes for the calendar year will be $1,000 or less, and you would like to file Form 944 instead of Forms 941, you must contact the IRS to request to file Form 944. You must receive written notice from the IRS to file Form 944 instead of Forms 941 before you may file this form. For more information on requesting to file Form 944, see the Instructions for Form 944.
Employers can request to file Forms 941 instead of Form 944.(p3)
If you received notice from the IRS to file Form 944 but would like to file Forms 941 instead, you must contact the IRS to request to file Forms 941. You must receive written notice from the IRS to file Forms 941 instead of Form 944 before you may file these forms. For more information on requesting to file Form 941, see the Instructions for Form 944.
Aggregate Form 941 filers.(p3)
Agents must complete Schedule R (Form 941), Allocation Schedule for Aggregate Form 941 Filers, when filing an aggregate Form 941. Aggregate Forms 941 can only be filed by agents approved by the IRS under section 3504 of the Internal Revenue Code. To request approval to act as an agent for an employer, the agent files Form 2678, Employer/Payer Appointment of Agent, with the IRS.
Aggregate Form 940 filers.(p3)
Agents must complete Schedule R (Form 940), Allocation Schedule for Aggregate Form 940 Filers, when filing an aggregate Form 940, Employer's Annual Federal Unemployment (FUTA) Tax Return. Aggregate Forms 940 may only be filed by agents acting on behalf of home care service recipients who receive home care services through a program administered by a federal, state, or local government. To request approval to act as an agent on behalf of home care service recipients, the agent files Form 2678 with the IRS.
Electronic filing and payment.(p3)
Now, more than ever before, businesses can enjoy the benefits of filing and paying their federal taxes electronically. Whether you rely on a tax professional or handle your own taxes, the IRS offers you convenient programs to make filing and payment easier.
Spend less time and worry about taxes and more time running your business. Use e-file and EFTPS to your benefit.
  • For e-file, visit for additional information.
  • For EFTPS, visit or call EFTPS Customer Service at 1-800-555-4477 or 1-800-733-4829 (TDD).
Electronic submission of Forms W-4, W-4P, W-4S and W-4V.(p3)
You may set up a system to electronically receive any or all of the following forms (and their Spanish versions, if available) from an employee or payee.
  • Form W-4, Employee's Withholding Allowance Certificate.
  • Form W-4P, Withholding Certificate for Pension or Annuity Payments.
  • Form W-4S, Request for Federal Income Tax Withholding From Sick Pay.
  • Form W-4V, Voluntary Withholding Request.
For each form that you establish an electronic submission system for, you must meet each of the following five requirements.
  1. The electronic system must ensure that the information received by the payer is the information sent by the payee. The system must document all occasions of user access that result in a submission. In addition, the design and operation of the electronic system, including access procedures, must make it reasonably certain that the person accessing the system and submitting the form is the person identified on the form.
  2. The electronic system must provide exactly the same information as the paper form.
  3. The electronic submission must be signed with an electronic signature by the payee whose name is on the form. The electronic signature must be the final entry in the submission.
  4. Upon request, you must furnish a hard copy of any completed electronic form to the IRS and a statement that, to the best of the payer's knowledge, the electronic form was submitted by the named payee. The hard copy of the electronic form must provide exactly the same information as, but need not be a facsimile of, the paper form. For Form W-4, the signature must be under penalty of perjury, and must contain the same language that appears on the paper version of the form. The electronic system must inform the employee that he or she must make a declaration contained in the perjury statement and that the declaration is made by signing the Form W-4.
  5. You must also meet all recordkeeping requirements that apply to the paper forms.
For more information, see:
  • Regulations sections 31.3402(f)(5)-1(c) (for Form W-4), and
  • Announcement 99-6 (for Forms W-4P, W-4S, and W-4V). You can find Announcement 99-6 on page 24 of Internal Revenue Bulletin 1999-4 at

Furnishing Form W-2 to employees electronically.(p4)
You may set up a system to furnish Form W-2 electronically. Each employee participating must consent (either electronically or by paper document) to receive his or her Form W-2 electronically, and you must notify the employee of all hardware and software requirements to receive the form. You may not send a Form W-2 electronically to any employee who does not consent or who has revoked consent previously provided.
To furnish Forms W-2 electronically, you must meet the following disclosure requirements and provide a clear and conspicuous statement of each requirement to your employees.
  • The employee must be informed that he or she will receive a paper Form W-2 if consent is not given to receive it electronically.
  • The employee must be informed of the scope and duration of the consent.
  • The employee must be informed of any procedure for obtaining a paper copy of his or her Form W-2 and whether or not the request for a paper statement is treated as a withdrawal of his or her consent to receiving his or her Form W-2 electronically.
  • The employee must be notified about how to withdraw a consent and the effective date and manner by which the employer will confirm the withdrawn consent. The employee must also be notified that the withdrawn consent does not apply to the previously issued Forms W-2.
  • The employee must be informed about any conditions under which electronic Forms W-2 will no longer be furnished (for example, termination of employment).
  • The employee must be informed of any procedures for updating his or her contact information that enables the employer to provide electronic Forms W-2.
  • The employer must notify the employee of any changes to the employer's contact information.

1. Who Are Employees?(p5)

For Use in Calendar Year 2015
Before you can know how to treat payments that you make to workers for services, you must first know the business relationship that exists between you and the person performing the services. The person performing the services may be:
This discussion explains these four categories. A later discussion, Employee or Independent Contractor in section 2, points out the differences between an independent contractor and an employee and gives examples from various types of occupations.
If an individual who works for you is not an employee under the common-law rules (see section 2), you generally do not have to withhold federal income tax from that individual's pay. However, in some cases you may be required to withhold under the backup withholding requirements on these payments. See Publication 15 (Circular E) for information on backup withholding.

Independent Contractors(p5)

For Use in Calendar Year 2015
People such as doctors, veterinarians, and auctioneers who follow an independent trade, business, or profession in which they offer their services to the public, are generally not employees. However, whether such people are employees or independent contractors depends on the facts in each case. The general rule is that an individual is an independent contractor if you, the person for whom the services are performed, have the right to control or direct only the result of the work and not the means and methods of accomplishing the result.

Common-Law Employees(p5)

For Use in Calendar Year 2015
Under common-law rules, anyone who performs services for you is generally your employee if you have the right to control what will be done and how it will be done. This is so even when you give the employee freedom of action. What matters is that you have the right to control the details of how the services are performed. For a discussion of facts that indicate whether an individual providing services is an independent contractor or employee, see section 2.
If you have an employer-employee relationship, it makes no difference how it is labeled. The substance of the relationship, not the label, governs the worker's status. It does not matter whether the individual is employed full time or part time.
For employment tax purposes, no distinction is made between classes of employees. Superintendents, managers, and other supervisory personnel are all employees. An officer of a corporation is generally an employee; however, an officer who performs no services or only minor services, and neither receives nor is entitled to receive any pay, is not considered an employee. A director of a corporation is not an employee with respect to services performed as a director.
You generally have to withhold and pay income, social security, and Medicare taxes on wages that you pay to common-law employees. However, the wages of certain employees may be exempt from one or more of these taxes. See Employees of Exempt Organizations (section 3) and Religious Exemptions and Special Rules for Ministers (section 4).

Additional information.(p5)

For Use in Calendar Year 2015
For more information about the treatment of special types of employment, the treatment of special types of payments, and similar subjects, see Publication 15 (Circular E) or Publication 51 (Circular A), Agricultural Employer's Tax Guide.

Statutory Employees(p5)

For Use in Calendar Year 2015
If workers are independent contractors under the common law rules, such workers may nevertheless be treated as employees by statute, (also known as "statutory employees") for certain employment tax purposes. This would happen if they fall within any one of the following four categories and meet the three conditions described next under Social security and Medicare taxes.
  1. A driver who distributes beverages (other than milk) or meat, vegetable, fruit, or bakery products; or who picks up and delivers laundry or dry cleaning, if the driver is your agent or is paid on commission.
  2. A full-time life insurance sales agent whose principal business activity is selling life insurance or annuity contracts, or both, primarily for one life insurance company.
  3. An individual who works at home on materials or goods that you supply and that must be returned to you or to a person you name, if you also furnish specifications for the work to be done.
  4. A full-time traveling or city salesperson who works on your behalf and turns in orders to you from wholesalers, retailers, contractors, or operators of hotels, restaurants, or other similar establishments. The goods sold must be merchandise for resale or supplies for use in the buyer's business operation. The work performed for you must be the salesperson's principal business activity. See Salesperson in section 2.

Social security and Medicare taxes.(p6)

For Use in Calendar Year 2015
You must withhold social security and Medicare taxes from the wages of statutory employees if all three of the following conditions apply.

Federal unemployment (FUTA) tax.(p6)

For Use in Calendar Year 2015
For FUTA tax (the unemployment tax paid under the Federal Unemployment Tax Act), the term "employee" means the same as it does for social security and Medicare taxes, except that it does not include statutory employees defined earlier in categories 2 and 3. Any individual who is a statutory employee described earlier under category 1 or 4 is also an employee for FUTA tax purposes and subject to FUTA tax.

Income tax.(p6)

For Use in Calendar Year 2015
Do not withhold federal income tax from the wages of statutory employees.

Reporting payments to statutory employees.(p6)

For Use in Calendar Year 2015
Furnish Form W-2 to a statutory employee, and check "Statutory employee" in box 13. Show your payments to the employee as "other compensation" in box 1. Also, show social security wages in box 3, social security tax withheld in box 4, Medicare wages in box 5, and Medicare tax withheld in box 6. The statutory employee can deduct his or her trade or business expenses from the payments shown on Form W-2. He or she reports earnings as a statutory employee on line 1 of Schedule C (Form 1040), Profit or Loss From Business, or Schedule C-EZ (Form 1040), Net Profit From Business. A statutory employee's business expenses are deductible on Schedule C (Form 1040) or C-EZ (Form 1040) and are not subject to the reduction by 2% of his or her adjusted gross income that applies to common-law employees.

H-2A agricultural workers.(p6)

For Use in Calendar Year 2015
On Form W-2, do not check box 13 (Statutory employee), as H-2A workers are not statutory employees.

Statutory Nonemployees(p6)

For Use in Calendar Year 2015
There are three categories of statutory nonemployees: direct sellers, licensed real estate agents, and certain companion sitters. Direct sellers and licensed real estate agents are treated as self-employed for all federal tax purposes, including income and employment taxes, if:

Direct sellers.(p6)

For Use in Calendar Year 2015
Direct sellers include persons falling within any of the following three groups.
  1. Persons engaged in selling (or soliciting the sale of) consumer products in the home or place of business other than in a permanent retail establishment.
  2. Persons engaged in selling (or soliciting the sale of) consumer products to any buyer on a buy-sell basis, a deposit-commission basis, or any similar basis prescribed by regulations, for resale in the home or at a place of business other than in a permanent retail establishment.
  3. Persons engaged in the trade or business of delivering or distributing newspapers or shopping news (including any services directly related to such delivery or distribution).
Direct selling includes activities of individuals who attempt to increase direct sales activities of their direct sellers and who earn income based on the productivity of their direct sellers. Such activities include providing motivation and encouragement; imparting skills, knowledge, or experience; and recruiting.

Licensed real estate agents.(p6)

For Use in Calendar Year 2015
This category includes individuals engaged in appraisal activities for real estate sales if they earn income based on sales or other output.

Companion sitters.(p6)

For Use in Calendar Year 2015
Companion sitters are individuals who furnish personal attendance, companionship, or household care services to children or to individuals who are elderly or disabled. A person engaged in the trade or business of putting the sitters in touch with individuals who wish to employ them (that is, a companion sitting placement service) will not be treated as the employer of the sitters if that person does not receive or pay the salary or wages of the sitters and is compensated by the sitters or the persons who employ them on a fee basis. Companion sitters who are not employees of a companion sitting placement service are generally treated as self-employed for all federal tax purposes.

Misclassification of Employees(p6)

For Use in Calendar Year 2015

Consequences of treating an employee as an independent contractor.(p6)

For Use in Calendar Year 2015
If you classify an employee as an independent contractor and you have no reasonable basis for doing so, you are liable for employment taxes for that worker and the relief provision, discussed next, will not apply. See section 2 in Publication 15 (Circular E) for more information.

Relief provision.(p7)

For Use in Calendar Year 2015
If you have a reasonable basis for not treating a worker as an employee, you may be relieved from having to pay employment taxes for that worker. To get this relief, you must file all required federal information returns on a basis consistent with your treatment of the worker. You (or your predecessor) must not have treated any worker holding a substantially similar position as an employee for any periods beginning after 1977.
Technical service specialists.(p7)
This relief provision does not apply for a technical services specialist you provide to another business under an arrangement between you and the other business. A technical service specialist is an engineer, designer, drafter, computer programmer, systems analyst, or other similarly skilled worker engaged in a similar line of work.
This limit on the application of the rule does not affect the determination of whether such workers are employees under the common-law rules. The common-law rules control whether the specialist is treated as an employee or an independent contractor. However, if you directly contract with a technical service specialist to provide services for your business and not for another business, you may still be entitled to the relief provision.
Test proctors and room supervisors.(p7)
The consistent treatment requirement does not apply to services performed after December 31, 2006, by an individual as a test proctor or room supervisor assisting in the administration of college entrance or placement examinations if the individual:

Voluntary Classification Settlement Program (VCSP).(p7)

For Use in Calendar Year 2015
Employers who are currently treating their workers (or a class or group of workers) as independent contractors or other nonemployees and want to voluntarily reclassify their workers as employees for future tax periods may be eligible to participate in the VCSP if certain requirements are met. To apply, use Form 8952, Application for Voluntary Classification Settlement Program (VCSP). For more information, visit and enter "VCSP" in the search box.
