ARP Data Manager

Calculation of Employer Match

M = A x W

A = Applied Match Percent (%)
W = ARP Gross Wages ($)

For all employees entitled to Employer Matching Contribution, the calculation is:
A = the lesser of:
(E + T + R) / W
3.00% of ARP Gross Wages (Regular 12-month employees)
3.26% of ARP Gross Wages (Educational 10-month employees)

E = Employee Total Pre-tax Contribution ($)
T = Employee Total After Tax Contribution ($)
R = Employee Total Roth 403B Contribution ($)

Rounding for the Applied Match Percent is done only at the final calculation of M, Employer Matching Contribution ($). Calculations using any other rounding methodology may produce results which vary from those of the ARP Data Manager by a few pennies.

Local Hire Guidelines (LHGL):

After providing your LHGL Resolution Document and Rollout Data to the NAD ARP Office, you must configure the ARP Data Manager for these criteria.

From the Main Menu, click <Settings> | <Identity, Folders, and Payroll>. In the Local Hire 2011 Group Box, select the Employer Option Code you have decided to apply from the drop down list, then enter your rollout date. When finished, click <OK> at the bottom of the dialog.

If you selected "B", then all of the employees in the database will be coded "1",
If you selected "V", then all the employees will be coded "2".

If you selected "G" or "P", you will be presented with a dialog which will enable you to enter the employee codes permited for your selected employer code for each employee.

Error Checks:

The Hire Date must always be after the Birth Date. Otherwise a FATAL ERROR will be generated.
The only organizations who may properly provide a Compliance Group code of "M" are the GC Mission Service and Guam Micronesia Mission. A fatal error will be generated for any others attempting to use the Compliance Group code of "M".

Both the Hire Date and Status Date must precede the Payroll Date.

The Status Date must be on or after the Hire Date.

Foreign Addresses and Use of Country Field:

Foreign addresses can be entered in a similar manner as US addresses with a few exceptions as noted below. The error check algorithm no longer requires that the Zip / Postal Code be all integers nor does it generate a fatal error if left blank. Canadian Postal Codes can now be entered, and in those cases where a foreign country has no postal codes, the zip code field should be left blank.

When the employee's address is in a foreign country OTHER THAN CANADA click <Other> in the Country Radio Group. Select the country name from the dropdown list of foreign countries that is now visible. Following your selection of the country name, its code will be written to the State field.

For Canadian addresses, click <Canada> in the Country Radio Group. Select the Canadian Province from the State dropdown list. Enter the Canadian Postal Code in the Zipcode Field.

VERY IMPORTANT! The country field MUST be left blank when the employee's address is in the United States or one of its territories.

All Checkboxes

The purpose of a Checkbox is to indicate a True or False condition. Checked indicates True; unchecked indicates False. Please look carefully when determining whether a checkbox is checked. A checked checkbox (True) contains a dark black check mark. An unchecked checkbox (False) contains nothing; i.e., it is blank. A gray check mark in a checkbox is a null value; i.e., neither checked nor unchecked, and the program treats it in the same manner as unchecked (False).

Payroll Items Maintained in the Databases Dialog

The following items can also be entered in the Batch Identification Dialog at export, but it's better to assign them in the Databases Dialog where you can see the items in these categories that you've assigned to other payrolls.

Payroll Run Reference (RunRef)

The Payroll Run Reference is a 3-character alphanumeric string. Assign one unique Run Ref to each of your payroll databases. Each of your unique payroll types should be assigned a likewise unique RunRef. Once a RunRef is assigned to a payroll type, do not change it.

Payroll ID

The Payroll ID is a 3-character alphanumeric string that becomes the last three characters of the Payroll Reference / File Name of your payroll file. This item can be changed, or it can remain the same, from one payroll to the next. If the occasion arises requiring replacement of a payroll file that has already been accepted, one or more of these three characters can be changed to avoid attempting to upload a file whose name has already been used.

Pay Frequency

Self-explanatory: Monthly, Semi-monthly, Bi-weekly, etc.

Pay Period

The payroll period number for the current calendar year. This value is auto-incremented following a successful export and upload.

Pay Date

Self-explanatory: Following a successful export and upload, the pay date is set to the next pay date based on the pay frequency.

ARP Data Manager Current Version: 5.2.0 Build 181

Version 5.1.8 Build 177 enables calculation of employee after-tax withholding. A new field is added to the table for total after-tax. The after-tax data is now handled similar to pre-tax and roth; i.e., the percent withholding is multiplied by the gross wage amount, and the result added to any fixed dollar amount withholding.

Version 5.1.9 Build 179 corrects a problem in the error check algorithm involving after tax contribution and employer match.

Version 5.2.0 Build 181 incorporates in the Error Check algorithm a fatal error that is triggered by the presence of any "S" Status Code. The "S" Status Code is no longer used effective January 1, 2019.

Prior to updating, you should ensure that no one is currently using the ARP Data Manager.

The update to ARP Data Manager Version 5.2.0 Build 181 is contained in a compressed file, "ARP520.zip". In response to the Download Dialog, click <Save>. Save the Zip file to the folder from which you run ARP Data Manager. You can ascertain that location by right-clicking the desktop icon for ARP Data Manager, then click <Properties>. In the Properties Dialog, the path to your ARP Data Manager is in the Target Folder Field. Once you've saved the zip file, open your Windows Explorer, navigate to the folder in which you saved the zip file. Right-click the file name, ARP520.zip, and select "Extract All...". Navigate the dialogs to the folder from which you run ARP Data Manager. Confirm by clicking <Yes> to overwrite the existing files. After clicking <Finish>, your update should be installed and ready to run.
