Does anyone know if I can switch from accrual to cash basis in QB Online to get cash basis financials to our tax accountant and then switch back to accrual without issue?

Hello, kturner1. 

Yes, you can switch to Cash basis in QuickBooks Online without any issues. I'm happy to show you the steps below. 

There are two ways to do this. You can either change the basis in the Account and settings page or within a specific report. Here's how to do it:

1. Click the gear icon, then select Account and settings.
2. Go to the Advanced tab.
3. Expand the Accounting section.
4. Select Cash from the Accounting method drop-down menu. 
5. Click Save, then Done. 

On the reports, simply select Cash under the Accounting method section. 

Changing the basis will only affect the transactions' reporting. Though, just make sure you get an approval from the IRS (through your tax accountant). They require you to use the same accounting method from year to year.
