Tax roundign

Hi all,


I'm using Quickbooks for Canada via API, and when using the GST/QST QC combined tax (5% + 9.975%) I'm having issues on roundings.


Let me give you an example.

For an amount of $8.70, we have: 

  • GST @ 5% on 8.70 = $0.435
  • QST @ 9.975% on 8.70 = $0.867825

Summing all (8,70+0,435+0,867825) we have $10,002825, which should round to $10.


The issue is that Quickbooks is rounding every parcel before the final sum, so:

  • GST @ 5% on 8.70 = $0.44
  • QST @ 9.975% on 8.70 = $0.87

Summing all (8,70+0,44+0,87) we have $10,01, which is not what was expected to.


I tried to follow this:

  1. Go to the Settings (gear icon) menu, then select Company Settings.
  2. Go to the Sales tab, then click the "Sales form content" section/
  3. Make sure that the "Round off final amounts for sales transactions" is ticked, then click the Save button.
  4. Go to the Expenses tab, then click the "Bills and expenses" section.
  5. Make sure that the "Round off final amounts for expense transactions" is ticked, then click Save and then Done


But there's no option "Round off final amounts for sales transactions", as you can see attached.


How can I solve this?
