I appreciate your time coming back here, @Dominika_.
Thank you for the additional details you've shared here. Now I understand better your situation with handling multiple transactions from different countries.
I want to share some insights about this feature you're looking for in QuickBooks Online Canada. Each version of our software has its own tax preference that's mainly based on a specific country where you're using QuickBooks from.
At the moment, the option to assign other countries to your tax settings in not yet an option. That is why the MTD setup is only available in the United Kingdom version of QuickBooks and can't be associated to Canadian QB.
With that being said, you will need to record and file your MTD outside the program for tax compliance. Also, with regards to the entries, they'll have to be recorded with great care so you can report them accurately.
You might want to reach out to a tax advisor to get help with manually recording your UK transactions. If you don't have one, we can help you find someone to help you. You can visit the following link to locate accountants based in Canada: https://quickbooks.intuit.com/ca/find-an-accountant/
Please get in touch with us again if you need further with your transactions and taxes. You can use this thread anytime.
