These year-end updates include the following changes:

Accounts Payable 1099s

New Form: The IRS has brought the 1099-NEC form out of retirement. The purpose of this form is to report any nonemployee compensation. Therefore, Nonemployee compensation is no longer included on the 1099-MISC form. In addition, some of the boxes on the 1099-MISC form have been renumbered and/or renamed. The 1099 Preview (03.730.00) and 1099 Forms (03.740.00) reports now allow users to select a “MISC” or “NEC” format. Similarly, the Generate 1099 Electronic File (03.742.00) process has a Form drop down which allows users to choose “1099-MISC” or “1099-NEC”.

The Vendor Maintenance (03.270.00) screen; 1099 Info tab has been updated in accordance with the two 1099 forms for 2020. The Default 1099 Box Number dropdown list has been synchronized with the box numbers/names on each form. All other Accounts Payable screens that display AP transaction “1099 Box” data, have been updated as well.

State Higher Withholding and Marital Status Options

The year-end updates also include:

  • Support for higher withholding tables by states. If a state provides tables for higher withholding statuses, the tables may be specified for the deduction Payroll Tables.
  • Marital status can be specified per deduction. If a marital status is specified for a deduction that differs from the status identified on the main Employee tab, the status for the deduction will be applied.

Final Thoughts

A service pack, hotfix, or download may cause interoperability issues with customizations and third-party products that work with your Microsoft Dynamics installation. Before applying any service pack, hot fix, or download, we strongly recommend that you:

  • Make a backup of your Microsoft Dynamics SL system and database
  • Verify that your environment is compatible with the update/service pack/hot fix/download
