How do I change accounting period for last year in QB to see previous calculations

Hi LiudmylaChern,

If you have other questions in mind, feel free to go back to this thread.

The Taxes section no longer supports VAT for the previous year unless you started using QBO last year. However, you can run VAT reports and adjust the date range to capture your last year's transactions, so you have bases for your VAT filings.

1. Go to Reports.
2. Search for VAT and choose the report that you can use.
