If you want the IRS to contact you via email, also provide your email address.

.06 Any questions about the specifications, especially those for the red-ink Form W-2 (Copy A) and Form W-3, should be emailed to Substituteforms@irs.gov. Please enter “Substitute Forms” on the subject line. Or send your questions to:

Internal Revenue Service Attn: Substitute Forms Program SE:W:CAR:MP:P:TP 1111 Constitution Ave. NW Room 6554 Washington, DC 20224

Any questions about the substitute black-and-white Form W-2 (Copy A) and Form W-3 should be emailed to copy.a.forms@ssa.gov or sent to:

Social Security Administration Direct Operations Center Attn: Substitute Black-and-White Copy A Forms, Room 341 1150 E. Mountain Drive Wilkes-Barre, PA 18702-7997

Note. You should receive a response within 30 days from either the IRS or the SSA.

.07 Forms W-2 and W-3 are subject to annual review and possible change. Therefore, employers are cautioned against overstocking supplies of privately printed substitutes.

.08 Separate instructions for Forms W-2 and W-3 are provided in the 2022 General Instructions for Forms W-2 and W-3. Form W-3 should be used only to transmit paper Forms W-2 (Copy A). Form W-3 is a single sheet including only essential filing information. Be sure to make a copy of your completed Form W-3 for your records. You can order current year official IRS Forms W-2, W-2AS, W-2GU, W-2VI, W-3, and W-3SS, and the 2022 General Instructions for Forms W-2 and W-3, online at IRS.gov/OrderForms. The IRS provides only cut sheet sets of Forms W-2 and cut sheets of Form W-3.

.09 Because substitute Forms W-2 (Copy A) and Form W-3 are machine-imaged and scanned by the SSA, the forms must meet the same specifications as the official IRS Forms W-2 and Form W-3 (as shown in the exhibits).

August 1, 2022 116 Bulletin No. 2022–31

Section 1.4 – General Rules for Filing Forms W-2 (Copy A) Electronically

.01 As of the date of publication of this revenue procedure, employers must file Forms W-2 (Copy A) with the SSA electronically if they are required to file 250 or more for a calendar year unless the IRS grants a waiver. However, see IRS.gov/FormW2 for any changes in this requirement. The SSA publication EFW2, Specifications for Filing Forms W-2 Electronically, contains specifications and procedures for electronic filing of Form W-2 information with the SSA. Employers are cautioned to obtain the most recent revision of EFW2 (and supplements) in case there are any subsequent changes in specifications and procedures.

.02 You may obtain a copy of the EFW2 by:

.03 Electronic filers do not file a paper Form W-3. See the SSA publication EFW2 for guidance on transmitting Form W-2 (Copy A) information to the SSA electronically.

.04 Employers are encouraged to electronically file Forms W-2 (Copy A) with the SSA even if not required. Doing so will enhance the timeliness and accuracy of forms processing. You may visit the SSA’s employer website at www.ssa.gov/employer. This helpful site has links to Business Services Online (BSO) and tutorials on registering and using BSO to file your Forms W-2.

.05 Employers who do not comply with the electronic filing requirements for Form W-2 (Copy A) and who are not granted a waiver by the IRS may be subject to penalties. Employers who file Form W-2 information with the SSA electronically must not send the same data to the SSA on paper Forms W-2 (Copy A). Any duplicate reporting may subject filers to unnecessary contacts by the SSA or the IRS.

.03 All printing of red-ink substitute Forms W-2 (Copy A) and Form W-3 must be in Flint red OCR dropout ink except as specified below. The following must be printed in nonreflective black ink.

  • Identifying number “22222” for Forms W-2 (Copy A) and “33333” for Form W-3 at the top

of the forms.

  • Tax year at the bottom of the forms.

  • The four (4) corner register marks on the forms.

  • The form identification number (“W-3”) at the bottom of Form W-3.

  • All the instructions below Form W-3 beginning with “Send this entire page….” line to the

bottom of Form W-3.

.04 The vertical and horizontal spacing for all federal payment and data boxes on Forms W-2 and W-3 must meet specifications. On Form W-3 and Form W-2 (Copy A), all the perimeter rules must be 1-point (0.014-inch), while all other rules must be one-half point (0.007-inch). Vertical rules must be parallel to the left edge of the form; horizontal rules parallel to the top edge.

.05 The official red-ink Form W-3 and Form W-2 (Copy A) are 7.50 inches wide. Employers filing Forms W-2 (Copy A) with the SSA on paper must also file a Form W-3. Form W-3 must be the same width (7.50 inches) as the Form W-2. One Form W-3 is printed on a standard size 8.5 x 11-inch page. Two official Forms W-2 (Copy A) are contained on a single 8.5 x 11-inch page (exclusive of any snap-stubs).

.06 The top, left, and right margins for the Form W-2 (Copy A) and Form W-3 are 0.50 inches (1/2 inch). All margins must be free of printing except for the words “DO NOT STAPLE” on red-ink Form W-3. The space between the two Forms W-2 (Copy A) is 1.33 inches.

August 1, 2022 118 Bulletin No. 2022–31

.07 The identifying numbers are “22222” for Form W-2 (Copies A (and 1)) and “33333” for Form W-3. No printing should appear anywhere near the identifying numbers.

Note. The identifying number must be printed in nonreflective black ink in OCR-A font of 10 characters per inch.

.08 The depth of the individual scannable image on a page must be the same as that on the official IRS forms. The depth from the top line to the bottom line of an individual Form W-2 (Copy A) must be 4.17 inches and the depth from the top line to the bottom line of Form W-3 must be 4.67 inches.

.09 Continuous-pinfed Forms W-2 (Copy A) must be separated into 11-inch deep pages. The pinfed strips must be removed when Forms W-2 (Copy A) are filed with the SSA. The two Forms W-2 (Copy A) on the 11-inch page must not be separated (only the pages are to be separated (burst)). The words “Do Not Cut, Fold, or Staple Forms on This Page” must be printed twice between the two Forms W-2 (Copy A) in Flint red OCR dropout ink. All other copies (Copies 1, B, C, 2, and D) must be able to be distinguished and separated into individual forms.

.10 Box 12 of Form W-2 (Copy A) contains four entry boxes—12a, 12b, 12c, and 12d. Do not make more than one entry per box. Enter your first code in box 12a (for example, enter Code D in box 12a, not 12d, if it is your first entry). If more than four items need to be reported in box 12, use a second Form W-2 to report the additional items (see “Multiple forms” in the 2022 General Instructions for Forms W-2 and W-3). Do not report the same federal tax data to the SSA on more than one Form W-2 (Copy A). However, repeat the identifying information (employee’s name, address, and SSN; employer’s name, address, and EIN) on each additional form.

.11 The checkboxes in box 13 of Form W-2 (Copy A) and in box b of Form W-3 must be 0.14 inches each. The space before the first checkbox is 0.24 inches; the spaces between the first and second checkboxes and between the second and third checkboxes must be 0.36 inches; the space between the third checkbox to the right border of box 13 should be 0.32 inches (see Exhibit A).

Note. More than 50% of an applicable checkbox must be covered by an “X.”

.12 All substitute Forms W-2 (Copy A) and Form W-3 in the red-ink format must have the tax year, form number, and form title printed on the bottom face of each form using type identical to that of the official IRS form. The red-ink substitute Form W-2 (Copy A) and Form W-3 must have the form producer’s EIN entered directly to the left of “Department of the Treasury,” in red.

.13 The words “For Privacy Act and Paperwork Reduction Act Notice, see the separate instructions.” must be printed in Flint red OCR dropout ink in the same location as on the official Form W-2 (Copy A). The words “For Privacy Act and Paperwork Reduction Act Notice, see the separate instructions.” must be printed at the bottom of the page of Form W-3 in black ink.

.14 The Office of Management and Budget (OMB) Number must be printed on substitute Forms W-3 and W-2 (on each ply) in the same location as on the official IRS forms.

Section 2.2 – Specifications for Substitute Black-and-White Form W-2 (Copy A) and Form W-3 Filed With the SSA

.01 Specifications for the SSA-approved substitute black-and-white Forms W-2 (Copy A) and Form W-3 are similar to the red-ink forms (Section 2.1) except for the items that follow (see Exhibits D and E). Exhibits are samples only and must not be downloaded to meet tax obligations.

  1. Forms must be printed on 8.5 x 11-inch single-sheet paper only. There must be two Forms W-2 (Copy A) printed on a page. There must be no horizontal perforations between the two Forms W-2 (Copy A) on each page.

  2. All forms and data must be printed in nonreflective black ink only.

  3. The data and forms must be programmed to print simultaneously. Forms cannot be produced separately from wage data entries.

  4. The forms must not contain corner register marks.

  5. The forms must not contain any shaded areas, including those boxes that are entirely shaded on the red-ink forms.

  6. Identifying numbers on both Form W-2 (Copy A) (“22222”) and Form W-3 (“33333”) must be preprinted in 14-point Arial bold font or a close approximation.

  7. The form numbers (“W-2” and “W-3”) must be in 18-point Arial font or a close approximation. The tax year (for example, “2022”) on Forms W-2 (Copy A) and Form W-3 must be in 20-point Arial bold font or a close approximation.

  8. No part of the box titles or the data printed on the forms may touch any of the vertical or horizontal lines, nor should any of the data intermingle with the box titles. The data should be centered in the boxes.

  9. Do not print any information in the margins of the substitute black-and-white Forms W-2 (Copy A) and Form W-3 (for example, do not print “DO NOT STAPLE” in the top margin of Form W-3).

  10. The word “Code” must not appear in box 12 on Form W-2 (Copy A).

  11. A 4-digit vendor code preceded by four zeros and a slash (for example, 0000/9876) must appear in 12-point Arial font, or a close approximation, under the tax year in place of the Cat. No. on Form W-2 (Copy A) and in the bottom right corner of the “For Official Use Only” box at the bottom of Form W-3. Do not display the form producer’s EIN to the left of “Department of the Treasury.” The vendor code will be used to identify the form producer.

  12. Do not print Catalog Numbers (Cat. No.) on either Form W-2 (Copy A) or Form W-3.

August 1, 2022 120 Bulletin No. 2022–31

  1. Do not print the checkboxes in:

    • Box 13 of Form W-2 (Copy A). The “X” should be programmed to be printed and

centered directly below the applicable box title.

  1. Do not print dollar signs. If there are no money amounts being reported, the entire field should be left blank.

  2. The space between the two Forms W-2 (Copy A) is 1.33 inches.

.02 You must submit samples of your substitute black-and-white Forms W-2 (Copy A) and Form W-3 to the SSA. Only black-and-white substitute Forms W-2 (Copy A) and Form W-3 for tax year 2022 will be accepted for approval by the SSA. Questions regarding other red-ink forms (that is, red-ink Forms W-2c, W-3c, 1099 series, 1096, etc.) must be directed to the IRS only.

.03 You will be required to send one set of blank and one set of dummy-data substitute blackand-white Forms W-2 (Copy A) and Forms W-3 for approval. Data entries on the sample forms must fill the length for each box, preferably using numeric data or alpha data, depending on the requirements. The “VOID” checkbox must be electronically checked on the dummy-data substitute black-and-white Form W-2 (Copy A). All “Xs” must show in box 13 centered under the applicable checkbox titles on the dummy-data substitute black-and-white Form W-2 (Copy A). All checkboxes on the dummy-data substitute black-and-white Form W-3 must be electronically checked in box b (Kind of Payer, Kind of Employer, and Third-party sick pay). Include in your submission the name, telephone number, fax number, and email address of a contact person who can answer questions regarding your sample forms.

.04 To receive approval, you may first contact the SSA via email at copy.a.forms@ssa.gov to obtain a template and further instructions. You can either submit your 2022 sample substitute black-and-white Forms W-2 (Copy A) and Forms W-3 in a pdf version electronically for approval to the copy.a.forms@ssa.gov mailbox or send your paper 2022 sample substitute black-and-white Forms W-2 (Copy A) and Forms W-3 to:

Social Security Administration Direct Operations Center Attn: Substitute Black-and-White Copy A Forms, Room 341 1150 E. Mountain Drive Wilkes-Barre, PA 18702-7997

Send your sample forms via private mail carrier or certified mail in order to verify their receipt. You can expect approval (or disapproval) by the SSA within 30 days of receipt of your sample forms.

.05 Vendor codes from the National Association of Computerized Tax Processors (NACTP) are required by those companies producing the W-2 family of forms as part of a product for resale to be used by multiple employers and payroll professionals. Employers developing Forms W-2 or W-3 to be used only for their individual company require a vendor code issued by the Social Security Administration.

.06 The 4-digit vendor code preceded by four zeros and a slash (0000/9876) must be preprinted on the sample substitute black-and-white Forms W-2 (Copy A) and Forms W-3. Forms not containing a vendor code will be rejected and will not be submitted for testing or approval. If you have a valid vendor code provided to you through the NACTP, you should use that code. If you do not have a valid vendor code, contact the Social Security Administration via email at copy.a.forms@ssa.gov to obtain an SSA-issued code. (Additional information on vendor codes may be obtained from the SSA or the NACTP via email at president@nactp.org.)

Bulletin No. 2022–31 121 August 1, 2022

.07 If you use forms produced by a vendor and have questions concerning approval, do not send the forms to the SSA for approval. Instead, you may contact the software vendor to obtain a copy of SSA’s dated approval notice supplied to that vendor.

.08 In response to feedback from the user community, the SSA (and the IRS) have added a 2-D barcoded version for the substitute Form W-2 and Form W-3 to the list of acceptable submission formats. This version is an optional alternative to the nonbarcoded substitute Forms W-2 and W-3. Both versions are fully supported by the SSA. At this time, neither the IRS nor the SSA mandates the use of 2-D barcoded substitute forms.

Note. The data contained in the barcode must not differ from the data displayed on the form. If they differ, the data in the barcode will be ignored and the data displayed on the form will be considered the submission. This also occurs when the barcode is not read correctly. The information on the form needs to be manually keyed into the database.

To get the barcode information:

subBarCodeStd.pdf.

If you are using a form produced by another vendor that contains a 2-D barcode, you must submit the form for approval using your own NACTP code. Prior to sending your first submission for approval, contact the SSA via email at copy.a.forms@ssa.gov to register your NACTP code and explain what forms you want to submit.

Section 2.3 – Requirements for Substitute Forms Furnished to Employees (Copies B, C, and 2 of Form W-2)

Note. Rules in Section 2.3 apply only to employee copies of Form W-2 (Copies B, C, and 2). Printers are cautioned that the paper filers who send Forms W-2 (Copy A) to the SSA must follow the requirements in Sections 2.1 and/or 2.2 above.

.01 All employers (including those who file electronically) must furnish employees with at least two copies of Form W-2 (three or more for employees required to file a state, city, or local income tax return). The following rules are guidelines for preparing employee copies.

The dimensions of these copies (Copies B, C, and 2), but not Copy A, may differ from the dimensions of the official IRS form to allow space for reporting additional information, including additional entries such as withholding for health insurance, union dues, bonds, or charity in box 14. The limitation of a maximum of four items in box 12 of Form W-2 applies only to Copy A, which is filed with the SSA.

Note. Employee copies (Copies B, C, and 2 of Form W-2) may be furnished electronically if employees give their consent (as described in Treasury Regulations Section 31.6051-1(j) ). See also Publication 15-A, Employer’s Supplemental Tax Guide.

.02 The minimum dimensions for employee copies only (not Copy A) of Form W-2 should be 2.67 inches deep by 4.25 inches wide. The maximum dimensions should be no more than 6.50 inches deep by no more than 8.50 inches wide.

Note. The maximum and minimum size specifications in this document are for tax year 2022 only and may change in future years.

August 1, 2022 122 Bulletin No. 2022–31

.03 Either horizontal or vertical format is permitted (see Exhibit F).

.04 The paper for all copies must be white and printed in black ink. The substitute Copy B, which employees are instructed to attach to their federal income tax returns, should be at least 9-pound paper (basis 17 x 22-500). Other copies furnished to employees should also be at least 9-pound paper (basis 17 x 22-500) unless a state, city, or local government provides other specifications.

.05 Employee copies of Form W-2 (Copies B, C, and 2), including those that are printed on a single sheet of paper, must be easily separated. The best method of separation is to provide perforations between the individual copies. Whatever method of separation is used, each copy should be easily distinguished.

Note. Perforation does not apply to printouts of copies of Forms W-2 that are furnished electronically to employees (as described in Treasury Regulations Section 31.6051-1(j) ). However, these employees should be cautioned to carefully separate the copies of Form W-2. See Publication 15-A for information on electronically furnishing Forms W-2 to employees.

.06 Interleaved carbon and chemical transfer paper employee copies must be clearly legible. Fading must be minimized to assure legibility.

.07 The electronic tax logo on the IRS official employee copies is not required on any of the substitute form copies. To avoid confusion and questions by employees, employers are encouraged to delete the identifying number (“22222”) from the employee copies of Form W-2.

.08 All substitute employee copies must contain boxes, box numbers, and box titles that match the official IRS Form W-2. Boxes that do not apply can be deleted. However, certain core boxes must be included. The placement, numbering, and size of this information is specified as follows.

  • The core boxes must be printed in the exact order shown on the official IRS form. The items

and box numbers that constitute the core data are:

Box 1 — Wages, tips, other compensation

Box 2 — Federal income tax withheld

Box 3 — Social security wages

Box 4 — Social security tax withheld

Box 5 — Medicare wages and tips

Box 6 — Medicare tax withheld

  • The core data boxes (1 through 6) must be placed in the upper right of the form. Substitute

vertical-format copies may have the core data across the top of the form. Boxes or other information will definitely not be permitted to the right of the core data.

  • The form title, number, or copy designation (B, C, or 2) may be at the top of the form.

Also, a reversed or blocked-out area to accommodate a postal permit number or other postal considerations is allowed in the upper right.

  • Boxes 1 through 6 must each be a minimum of 1 1/8 inches wide x 1/4 inch deep.

  • Other required boxes are:

a) Employee’s social security number

b) Employer identification number (EIN)

Bulletin No. 2022–31 123 August 1, 2022

c) Employer’s name, address, and ZIP code

e) Employee’s name

f) Employee’s address and ZIP code

Note. Employers may truncate the employee’s SSN on employee copies of Forms W-2. See the 2022 General Instructions for Forms W-2 and W-3 for more information.

Identifying items must be present on the form and be in boxes similar to those on the official IRS form. However, they may be placed in any location other than the top or upper right. You do not need to use the lettering system (a–c, e–f) used on the official IRS form. The employer identification number (EIN) may be included with the employer’s name and address and not in a separate box.

Note. Box d (“Control number”) is not required.

.09 All copies of Form W-2 furnished to employees must clearly show the form number, the form title, and the tax year prominently displayed together in one area of the form. The title of Form W-2 is “Wage and Tax Statement.” It is recommended (but not required) that this be located on the bottom left of substitute Forms W-2. The reference to the “Department of the Treasury — Internal Revenue Service” must be on all copies of substitute Forms W-2 furnished to employees. It is recommended (but not required) that this be located on the bottom right of Form W-2.

.10 If the substitute employee copies are labeled, the forms must contain the applicable description.

  • “Copy B, To Be Filed With Employee’s FEDERAL Tax Return.”

  • “Copy C, For EMPLOYEE’S RECORDS.”

  • “Copy 2, To Be Filed With Employee’s State, City, or Local Income Tax Return.”

It is recommended (but not required) that these be located on the lower left of Form W-2. If the substitute employee copies are not labeled as to the disposition of the copies, then written notification using similar wording must be provided to each employee.

.11 The tax year (for example, 2022) must be clearly printed on all copies of substitute Form W-2. It is recommended (but not required) that this information be in the middle at the bottom of the Form W-2. The use of 24-pt. OCR-A font is recommended (but not required).

.12 Boxes 1 and 2 (if applicable) on Copy B must be outlined in bold 2-point rule or highlighted in some manner to distinguish them. If “Allocated tips” are being reported, it is recommended (but not required) that box 8 also be outlined. If reported, “Social security tips” (box 7) must be shown separately from “Social security wages” (box 3).

Note. Box 8 may be omitted if not applicable.

.13 If employers are required to withhold and report state or local income tax, the applicable boxes are also considered core information and must be placed at the bottom of the form. State information is included in:
