TIP: For 2025 year-end specific resources, see Year-End Processing Resources for Calendar year 2025 Interim Release Download (IRD) - IRD 2025 is required and it installs on the versions listed below. Interim Release Downloads (IRDs) currently apply only to 1099 processing in Accounts Payable (AP). IRD installation will appear as "Installed End of Year Changes" in the Installed Modules Listing in Library Master / Reports. See Sage 100: Download Portal. Estimated release date is December 20, 2025.
Install the PR 2.26.0 update before running W2s and any other year-end forms. Year-end processing can be run before or after updating payroll to 2.26.0 and/or running W2s.
It’s recommended to finalize all postings for the 2025 payroll year and complete the year-end processing before making any entries for 2026. This is important because the year-end processing in the new Payroll 2.X (Sage 100 v2018 and newer) triggers essential calculations and rollovers, such as time off accruals, deduction goals, and Direct Deposit year-to-date amounts. It is possible to run payroll for the new year before completing the year-end processing. However, it's not the recommended practice.

It isn’t necessary to run W2's before running period-end processing. Sage 100 has partnered with Aatrix for forms processing since MAS90 4.50. The data tables that store tax reporting information maintain detailed records year-over-year in all versions.
If you’re running Sage 100 2018 or newer (“Payroll 2.X”), there’s no need to create a copy company, as the new payroll program keeps many detailed records year-over-year (according to the setting in Payroll Options). The exception is if you’re running Sage 2017 or older (“legacy payroll”), in which case a year-end copy company is required for record keeping in these retired versions.
Tax reporting forms, including W2s, should be run in the "live company" and not in a copy company. This ensures that the forms archive is maintained together in the same database.
Reopening a closed payroll year should be avoided whenever possible. Certain amounts, such as benefit accruals, are reset during year-end processing (unless the anniversary date reset option is used). Therefore, prior payroll years shouldn’t be reopened.
If checks were processed incorrectly, they should ideally be reversed and re-entered correctly. If this isn't possible, you can manually edit the wage and tax history. For detailed instructions, see Edit employee wage and tax history in Tax Summary
Year-end processing can be run before or after updating payroll to 2.26.0 and/or running W2s
Year-end Forms
Most forms can be printed on plain printer paper, but some require a pre-perforated 4-part blank page. The official red ink forms for certain government copies of W2/W3, 1099/1096, etc., are no longer required when printing forms from Aatrix Federal and State Tax Reporting. For more details, see Forms used to print W2s, 1095s and 1099s
Aatrix Tax Reporting forms update independently from the Sage 100 version, so even older versions may be able to run the 2025 W2 after updating the forms. However, only supported versions will receive the necessary year-end updates to ensure data is correctly routed from Sage 100 files to the Tax Reporting forms. Sage 100 support can’t assist with any issues running W2s or other Tax Reporting forms in unsupported versions. If needed, corrections can be made directly in the Aatrix form processor.
The NEC (Non-Employee Compensation) version of the 1099 is supported on all currently supported versions of Sage 100, from v2022 to 2025.
