Excel Upload Instructions

File Format Instructions for Uploading Wage and Withholding Detail

Maine Revenue Service’s Internet Filing System offers CQR and withholding filers the convenience of uploading wage and withholding information rather than typing this data in manually. To utilize this feature, users organize the required data in a Microsoft Excel spreadsheet file, which is then uploaded into Maine Revenue’s internet filing system. When the file is uploaded, the system will read the data in the first Worksheet in the file and place that data in the appropriate fields on the wage and withholding detail screen. The user should then review the data in the fields to verify its accuracy.

To take advantage of this feature, users must upload a file that conforms to the specifications below. Failing to format the file correctly will result in processing errors or inaccurate reporting.

NOTE: This system does not accept Excel files of any format other than .xls. Please not that Microsoft Excel 2007 will default to a file format of .xlsx when saving files. Therefore, users of Excel 2007 will need to select file format .xls when saving their file before trying to upload. Other Excel file formats (e.g. .xlt, .xla, .xlsb, .xlsm) are also not accepted.

General File Specifications

  • Only Microsoft Excel spreadsheet files with a file format of .xls will be accepted.
  • The file will contain only data; no headers, titles, or footers of any kind are to be entered.
  • The data must be on the first Worksheet in the Workbook.
  • The Worksheet within the file must contain exactly five (5) columns as described below. The data in some columns will be ignored if the filer type is inappropriate for that type of information.
  • The rows are to be contiguous; no empty rows are allowed.
  • Hidden columns are not allowed.
  • Formulas are not to be used.

The five required columns are as follows:

  1. Employee or payee’s Social Security number (SSN) or EIN.
  2. Wages paid to employees.
  3. Maine income tax withheld.
  4. Employee or payee’s name. (maximum of 70 characters)
  5. Seasonal indicator.

For your convenience, Maine Revenue Services has prepared a preformatted spreadsheet for each withholding return type (941ME or 941/C1-ME). These spreadsheets are available to be downloaded from the MRS web site.

Please note that if you copy your data from one Excel file to paste into another Excel file, you should highlight only the cells you want to copy; do not highlight the entire worksheet as doing so may create hidden formatting errors.

Specifications for Each Column

Column A- SSN or EIN

Column A contains the Social Security numbers of employees/payees or Employer Identification numbers of entities. IMPORTANT: Be sure this column is formatted as text before any entries are made. To do this, highlight Column A and then in your Excel toolbar click "Format" and then "Cells". You will then need to click "Text" and then "OK". It is important this is done in advance, otherwise any entries you make which start with zero (e.g. 001223333) will drop the leading zeroes. Numbers can be entered with or without hyphens(e.g. 001223333 or 001-22-3333). If you don't know the social security number for a particular employee/payee or if you don't know the Employer Identification number for a particular entity, enter 999999999. Except for unknown SSNs or EINs, column A data cannot contain any duplicate Social Security numbers except in the case of seasonal filers, in which case you may enter the same Social Security number twice (once for seasonal and once for non seasonal).

Column B- Wages Paid to Employees

This column is to report wages only; do not include nonwage distributions. Enter numbers only; do not include a dollar sign. Either whole numbers or numbers containing dollars and cents are acceptable. If the data has cents to report then the cents must be preceded with the decimal point and the value may not contain embedded spaces. Withholding only filers leave this column blank.

Column C- Maine Income Tax Withheld

Enter the amount of Maine income tax withheld for this employee or payee. Otherwise, this column has the same formatting as the wages column.

Column D- Employee or Payee’s Name

This column must contain a valid name. Enter each employee or payee’s last name, first name, and middle initial. Commas are not necessary and will be ignored if included. Enter the name of an employee with both non-seasonal and seasonal wages on two separate lines. The maximum field length is 70 characters.

Column E- Seasonal indicator

This column may contain a Boolean true for ‘is a seasonal’ or false for ‘is not a seasonal’. It may also contain a ‘1’, having the same meaning as the Boolean true, or a ‘0’, having the same meaning as the Boolean false. In addition, it may also contain a ‘Y’, having the same meaning as the Boolean true an ‘N’, having the same value as the Boolean false. The ‘Y’ and ‘N’ may be upper or lower case. Column E data will be ignored if the filer is non-seasonal. Withholding only filers leave this column blank.
