Vat reports are not working

Let's perform some troubleshooting steps to get your VAT report working, david-ca-fields-.

There are times when a browser's cache data becomes full of frequent access to web pages or damaged. This causes odd behavior in QuickBooks Online (QBO). To better isolate this issue, let's perform some steps below to confirm browser-related issues:

1. Try signing in to your QBO using a private or incognito window. (Ctrl + Shift + N for Google Chrome browser, Ctrl + Shift + P for Mozilla Firefox browser, Command + Option + P for Safari browser). 
2. Then, try running the VAT report again. See the Check how much sales tax you owe in QuickBooks Online article if you need to run VAT Liability report. 
3. If it works, go back to your regular browser and clear the cache to delete those temporarily stored files and browsing history. The overtime collection of data can create corruption, however, removing this should fix the issue.
4. You can also use supported, up-to-date browsers to roll out the possibility of a browser-related issue. 

If the same thing happens, I'd suggest contacting our Customer Support Team. They'll pull up your account in a secure environment and investigate what's causing this issue. Here's how:
