Looks as if there will be an Interim Release disk coming for each of the supported versions of Sage MAS 90 and 200 (and SQL). This will be in addition to the Service Update that was released on March 26 and included fixes for the Payroll 941 form changes and New Jersey payroll tax changes.
Some users had noted that they were unable to load a full service update due to the existence of third party enhancements which may require customization prior to loading a full service update.
The Interim Release Disks (there will be separate ones for the 2009 941 tax form as well as the NJ tax law) will first be available for the newest versions of Sage MAS 90 and 200 with releases for older versions following.
When available these IRD (Interim Release Disks) will be posted in the Sage Online Support Services (SOSS ) area.
Anyone needing to file immediately (and who is on version 4.3) can use the new integrated electronic tax filing that is included with the latest version of Sage MAS 90 and 200.
