If you are using QuickBooks 2009 to track and report Sales Tax, you need to update to QuickBooks 2009 Release 10 before submitting Sales Tax to your tax agency. To see what release of QuickBooks you are using, open QuickBooks and hit F2. The first line in the top left will show you what release you are on.
The QuickBooks 2009 Release 10 is different from most releases. If you are updating from Release 8 (R8), think of this update in the same way you treat an upgrade to a new year’s version. Both your program and data files will need to be updated. You must log into each company file as the QuickBooks Administrator for the file to update.
R10 is not backwards compatible with R8 or previous releases of QuickBooks 2009. QuickBooks 2009 Release 10 requires that ALL computers accessing QuickBooks company files be updated to R10, including the server. Refer to QuickBooks support for special Instructions for installing R10 on QuickBooks file servers.
You may need to resubmit your sales tax filings with your tax agency if you meet all three of the following criteria:
Criteria to use:
1.You downloaded and are using Release 9 for QuickBooks 2009 Simple Start, Pro, Premier or Enterprise Solutions; and
2.After installing Release 9 (made available on December 1, 2009), you used the Sales Tax Liability and / or Sales Tax Revenue Reports in QuickBooks to file Sales Tax information with your Tax Agency; and
3.The number of items in your Items List multiplied by the number of vendors in your Vendors List is greater than 10,000.
If you meet all three of the above criteria, then you should download Release 10, rerun the reports, and resubmit corrected sales tax information to the relevant authorities , if applicable.
