Nice to have you join this thread, Alex.
I recognise being able to upload an updated sample .IIF file to your QuickBooks Desktop (QBDT) can aid you in seamlessly running your business.
To seamlessly import your .IIF file, you'll want to ensure your QBDT is up to date with the newest features and fixes. This way, we can guarantee the program is running on the latest patches. Let me show you how:
- Go to the Help menu and select Update QuickBooks Desktop.
- Select the Update Now tab.
- Click Get Updates to start the download.
- When the download finishes, restart QuickBooks then accept the option to install the new release.
You can also check out this link for more details: Update QuickBooks Desktop to the latest release.
If the issue persists after updating QuickBooks, I recommend contacting our support team. One of our agents can look into your account and investigate why the sales tax code isn't assigned correctly.
Once everything is settled, feel free to check this article for reference in things you can do with your IIF file: Tasks you can do with IIF files.
I'll encourage you to post a reply in this thread whenever you need help importing your IIF file. I can also assist you if you have other QuickBooks related concerns. Keep safe and have a good one!
