    Ohio Department of Taxation Scannable Tax Forms
1. Introduction:
  The Ohio Department of Taxation (ODT) prescribes the format of Ohio tax returns and forms. 
  The department’s primary objective is to ensure that the tax forms are compatible with the 
  department’s automated remittance processing systems and can be processed in an efficient, 
  accurate and economical manner.
 
  These  guidelines  are  for  computerized  tax  processors,  software  developers,  computer 
  programmers, commercial printers, and others who develop and use substitute and reproduced 
  tax forms.

2. Definitions:
  2.01 Substitute Tax Forms –
        A form other than the official ODT form that is computer-produced, computer-programmed 
        or commercially typeset and printed. ODT must be able to process substitute tax forms 
        in the same manner as the official forms. Substitute tax forms that are electronically 
        produced must duplicate the appearance and layout of the official form including size of 
        margins, special keying symbols and line numbers.

  2.02  Facsimile (Text Mode) Forms  
        For filing purposes, ODT does not accept dot matrix facsimile signature returns and 
        schedules. They do not contain the data-entry symbols and other requirements necessary 
        for processing. Companies must clearly print in the top margin of electronically processed 
        text mode forms: “DO NOT FILE THIS FORM.”

  2.03  Scannable Tax Forms –
        The computer-prepared scannable forms are similar to the official ODT tax forms with 
        the following exceptions: 1) the taxpayer-entity information layout and 2) a scanline that 
        contains the taxpayers’ tax data.

  2.04 Reproduced Tax Forms –
        Reproduced  tax  forms  are  photocopies  of  the  official  ODT  forms.  ODT  accepts 
        reproductions of official forms if the reproductions are:

        1)  Facsimiles of the official form produced by photo-offset, photoengraving, photocopying 
        or other similar reproduction processes;
        2)  Printed in black ink on white paper of substantially the same weight, texture and quality 
        as the official forms;
        3)  Legible in both the original text of the form and the filled-in data; AND
        4)  The same dimensions as the official form, including the paper and the image produced on it.

        ODT accepts one-sided reproduced forms even if the official form is two-sided. However, 
        ODT prefers two-sided reproduced forms that result in the same page arrangements as 
        the official form. You may not file reproduced tax forms that do not meet the preceding 
        guidelines. Reproduced tax forms that deviate from the official forms are considered 
        substitute tax forms.

  2.05  ID Field –
        The area where the name, address, account number/Social Security number (SSN) are printed.

  2.06  Intelligent Character Recognition (ICR)-Readable Fields –
        Fields read using ICR technology. 



- 3 -
  2.07 Line Item Text 
        The text, including item numbers, specifying the information to be entered into a data field.

  2.08  Optical Character Recognition (OCR)-Readable Field –
        Scanline field read using OCR technology.

  2.09  Record Layout  
        A 6-line-per-inch vertical (row) and 10-characters-per-inch horizontal (column) spacing 
        grid,  specifying the exact placement of all fields and characters on the facsimile form, is 
        provided with each form specification to assist in proper spacing and alignment.
 
  2.10  Data Field  
        The specific space on the form where a numeric figure is entered.

3. Specifications: 
  3.01 Field Length –
        Each form must contain the exact number of ID fields, line item texts and data fields, as 
        the department-issued form.

  3.02  Name and Address –
        Name and address must be placed in the row and column specified in the grid format 
        provided with each form.

  3.03  Account/SSN – 
        The account or SSN(s) must be printed with spaces in the exact locations specified in 
        the record layout. 

  3.04  Scanline Font –
        The OCR scanline must be printed using a fixed 10-pitch, OCR-A (12-point size) font. 
        The use of Courier or OCR-B font is not permitted.

  3.05  Scanline Position – 
        ODT remittance scanline reads from right to left.  The bottom of the characters in the scanline 
        must be ½ of an inch from the bottom edge of the form and 1½ inches from the right edge. 
        See grid layout and Scanline Specifications Format for exact location of scanline.

  3.06 ICR  
        Dollar signs ($) are not permissible in ICR-readable fields. Commas and periods are not 
        allowed as separators between the digits in ICR-readable fields. ICR fields are defined 
        in the record layout of each form.

  3.07  Total Remittance Field –
        This is the remittance line on the form that shows the tax due amount and payment 
        submitted with the form. This field is read by the Courtesy Amount Reader (CAR) on 
        our remittance-processing equipment and requires a dollar sign ($) followed by a space 
        preceding the remitted amount. The total remittance field must also include a decimal 
        point to separate the dollar and cents digits. (Example: $ 12345.00)

  3.08  OCR/ICR Fields –
        Underlining or enclosing OCR/ICR readable data fields is not acceptable nor are vertical 
        bars to be used to separate dollar and cents fields.

  3.09  Finished Form Size  
        Form size is as specified in the grid layout for each form. Extraneous borders are not 
        permitted. Edges MUST be trimmed to meet specifications. DO NOT HAND-CUT BOTTOM 
        OR RIGHT SIDE OF FORM.  

  3.10  Paper Requirement –   
        The paper must be white, high-quality bond paper with a minimum weight between 20 
        and 24 pounds.

  3.11  Back of Form – 
        Forms must be printed on one side only, unless the form is a two sided form. If two-sided, 
        see section 2.04.

  3.12  Inks –
        Forms must be printed using black ink, non-MICR (non-ferrous) ink or toner.

  3.13  Shading –
        The use of shading or solid black areas for sidebars, headings or other areas is not 
        permitted unless specified on tax return samples.

  3.14  Reference Marks –
        On all scannable returns and vouchers there are target marks on the form. Exact locations 
        of the target marks are listed on the grid layout for each form. Target marks must be a 
        solid black box and should be .2”W x  .167”H.

  3.15  NEW for 2017/2018 vouchers: Software Developer Identification – 
        The software developer identification is a two-digit vendor registration number (VRN) 
        that will be assigned to each developer. The identification will be assigned to you by the 
        Ohio Department of Taxation. The two-digit VRN refers to the developer who designs 
        the software to perform the tax calculations and to the developer who designs the form 
        templates. The VRN must be printed on each document in the exact area specified on 
        the form grid. The use of a standard font size is acceptable. This is the same two-digit 
        number assigned to you on your full-page scannable forms. For any questions or 
        VRN assignments, email: Forms@tax.state.oh.us

4. Testing: 
  All documents must be tested on ODT equipment before production runs. The ODT requests 
  a certain amount (see section 8 for quantities) of test samples (cut to exact size) with the 
  appropriate scanline and all data fields filled. Test documents must be submitted for approval 
  to:   

                              Ohio Department of Taxation

6. Check Digit Routine (Modulus 10) For Scanline

     1)         Multiply each digit of the number by 1 or 2, starting from the left and going to the 
                right. Start with a 1 then 2, and continue this pattern to the end of that 
                number.
    2)          Add all the digits together. Do not add the sum of the totals. For example, if the 
                numbers are 1, 3, 4 and 19 your answer is: 1 + 3 + 4 + 1 + 9 = 18.
    3)          Divide the total from the digits by 10.
    4)          Subtract the remainder from 10. The answer is your check digit. If the  
                remainder is zero, the check digit is always zero.

     Note:  This same procedure is followed for all check digit calculations throughout these  
               specifications.

Example:

Check digit calculation for SSN and school district number:
 
Step 1 – Multiply each digit in the number by weights 121212.

       1  2  3  4  5   6   7   8   9  (SSN)                                2   5    0    9               (school district number)
 X 1  2  1  2  1   2   1   2   1                                         XX  1        1  22   1   1   22 0
       1  4  3  8  5  12  7  16  9                                    2 2   1010  0         180  18

Step 2 – The digits of the individual products are summed.

           1 + 4 + 3 + 8 + 5 + 1 + 2 + 7 + 1 + 6 + 9 = 47                                 2 + 1 + 0 + 0 + 1 + 8 = 12

Step 3 – Divide the sum by the modulus (10):

                                                 4 (quotient)                                                1 (quotient)
                      (Modulus) 10   47 (sum)                                           (Modulus)        10   12   (sum)
                                              40                                                            10
                                                 7 (remainder)                                            2  (remainder)

Step 4 – To compute the check digit:

  Modulus – Remainder = Check Digit                               Modulus – Remainder = Check Digit

  10 - 7 =    3 (This is the check digit.)                        10 - 2  =    8              (This is the check digit.)

Step 5 – Append a space and the check digit to the right of the number: The complete form for 
the SSN is 123456789 3 and for the school district number is 2509 8.
