There are regular updates throughout the year to payroll tax tables, already two since the initial release in late December 2020.
The current release is 2021.03 and you can check what version you’re running under <Help><About AccountMate> on the “Payroll” tab.
These mid-year updates are simple to perform as the process is automated, so if you see something less than 2021.03 then please hit <Utilities><Check for Payroll Tax Subscription Updates>. Don’t hesitate to ask iSOFT for help if you run into any issues.
