About the Tax Interface

If you require external taxing software to handle the computing of sales tax, you can use the Tax Interface, which supports these products:

• Vertex Sales Tax Q Series
• Taxware Sales/Use Tax System
• Taxware Enterprise
• Avalara AvaTax

In SyteLine, the tax interface is a separately licensed and installed product. To access the tax interface forms, you must be a licensed SyteLineTax user.

The Tax Interface is configured for the appropriate product with the Tax Interface Parameters form. After the interface is configured, taxes are automatically calculated on customer orders where the tax code is set to EXTRNL. (The EXTRNL tax code is added automatically to the Tax Codes form at a site when you enable the SyteLineTax module on the Optional Modules form.)

After the orders are invoiced, and before posting is performed, you must run the Tax Interface Post Register utility  to post the taxes to the external tax software.

If taxes are not being calculated correctly, you can use the Debug fields on the Tax Interface Parameters form to create log files that can help either Infor support or the appropriate tax system support to assist you.

If you are using AvaTax, use the Tax Interface Invoice Tax Credit form to give tax-exempt customers credit for taxes after an invoice has been created with taxes calculated.

What Information does the Interface Send to the Taxing Software?

Any order, RMA, invoice, credit memo or other information where the first tax code is set to EXTRNL is sent to the interface. (For compatibility with older versions of this interface, a tax code of VERTEX also causes taxes to be processed by the interface.) On the Tax Interface Parameters form, click Set All Customer Tax Code 1 to External to perform a system wide change that substitutes the selected tax interface in place of everything currently set to Tax Code 1.

The Tax System Interface can send this information, based on your selections on the Tax Interface Parameters form:

• Customer information: The interface sends this information from the Customer Ship To record: Customer Number, City, State, Zip, County
• Warehouse Information: If the warehouse can be determined, the City, State, Zip, and County of the warehouse is sent, as well as the Warehouse Code. This allows for more accurate taxation.  If the warehouse is not available, the address information from the General Parameters form is sent. You can also use the Warehouses tab on the Tax Interface Parameters form to specify the county where a warehouse is located.
• Item Information: Either Item or Product Code is sent based on the setting of the Send for Product field in the Tax Interface Parameters form.
• Freight and Miscellaneous Charges for Items: Freight is passed into your external tax system with the Freight flag set and the Item Number set to FREIGHT. Miscellaneous charges are sent with the Item Number set to MISC CHARGE
• Miscellaneous and Labor Charges for Service: Miscellaneous and Labor Service transactions use the Exclude Field Service Misc and Exclude Field Service Labor options on the Tax Interface Parameters form. If an option is selected (set to Exclude), then for all tax providers except the Taxware Sales/Use Tax System, the system sends SVC-MSC-EXEMPT or SVC-LBR-EXEMPT. For the Taxware Sales/Use Tax System, the system sends 89999 for both Labor and Miscellaneous Charges. If the options are not selected, indicating that the charges should be included, then the system sends the Misc/Work codes from the transactions.
