Welcome to the Community space, @sushil.

Let me share some insights about your QuickBooks license and how to migrate your data.

Since you're using US QuickBooks license for accounting of UK based subsidiary, you'll want to cancel the subscription and create a new account for UK version. Then export your lists and other data from US account to UK version. 

Here's how:

1. Log in to your new QuickBooks Online subscription.
2. Click the Gear icon.
3. Choose Export data.
4. Toggle the data you want to export to On. 
5. Click the Export to Excel button.

Once completed, you'd see a . ZIP file containing the exported data. If you need to get other transactions, you can use reports and export them.

Read through this article since there are other entries that you need to export separately: Export reports, lists, and other data from QuickBooks Online.

You can also utilize a third-party application to help migrate the entire data. Please visit our QuickBooks App store and find an app from there. Or you can use other apps outside of the store.

On the other hand, you can check our QuickBooks Data Service FAQ. It contains instructions that will help you migrating your data if you have QuickBooks Desktop.

Additionally, I'll be sharing this guide that will provide your tax reports and its summary: Tax reports.
