Microsoft Dynamics GP 2026 Mid-Year Update Released!

It’s mid-June, and that can only mean one thing—the much-awaited Microsoft Dynamics GP mid-year update is here!

This update includes tax changes for Canadian Payroll for the following:

British Columbia, Newfoundland and Labrador, and Prince Edward Island
T4127, Payroll Deductions Formulas effective July 1, 2026.

This update is primarily focused on our Canadian Payroll customers; however, it also includes a few quality improvements based on feedback from other customers.
- You are unable to submit the VAT return on 18.8 unless you are user SA.
- Human Resource Review Calendar Window stops at year 2026 on the drop-down list (workaround, leave year blank and will use the GP user date)
- Lockbox files import with 1926 year (workaround is to change the file to 4 digit year vs two)

Microsoft Dynamics GP version 18.8.1957
Canadian Payroll specific version 18.8.1954
