This faq is written for people who make instalment payments to pay their sales tax, and who have now just upgraded to the newest version of QuickBooks from Multicurrency 2008 or QuickBooks 2007 or earlier.

When you convert your company file, new versions of QuickBooks looks at your sales tax liability account to determine the amount of sales tax you've paid in the past, then makes general journal entries to account for your sales tax balances.

Therefore, if you tracked your sales tax payments in an account other than the sales tax liability account or in a sub account of ANY kind, QuickBooks will not factor in these amounts.

After you have converted your company file, when you open the File Sales Tax window or run the Tax Agency report, QuickBooks will ask you if you make instalment payments 

• If you make instalment payments select Yes. QuickBooks then displays a pdf. Here's where it gets a little tricky. 
   
• If you did NOT track your instalment payments to the sales tax liability account or to a sub account (even if it was a sub account of the salex tax liability account), print the pdf and follow its instructions to determine the amounts you need to enter in the next window.

• If you always tracked your instalment payments to the sales tax liability account, you can ignore this pdf (it doesn't apply to your situation). QuickBooks will ask you to enter the amount of your final payment you made for your last filing period and the date of that last payment. (Thats OK if the date of your last payment occurs past the date of your last filing period.)
  
  QuickBooks now has all the information it needs to calculate your sales tax balances.
