Hello, Denise. 

I'll ensure you'll be able to record your VAT exempt services. I'll also give some information about calculating corporation tax in QuickBooks. 

For VAT exempt services, you'll want to set up a service and tag it as Exempt. Then, you would enter the service using the transaction forms (invoices, estimates, bills, etc.) to record it. Simply click on the + New button, then select a transaction you want to create. 

With that said, here's how to tag a service as Exempt: 

1. Go to the Gear icon menu, then select Products and services.
2. Click the New button.
3. Select the type.
4. Enter the service details.
5. Under the VAT drop-down menu, select Exempt.
6. Once done, click Save and close.

If your service can either be VAT exempt or with VAT (depending on the circumstances), simply leave the VAT box as blank.

On any transaction form, you are given an option to tag a certain line item with the corresponding VAT options. 

Simply select Exempt under VAT for the line item if one particular service is exempted. Or, select No VAT under Amounts are if all line items are exempted. 

All entries will flow towards your VAT reports. If you need to see the affected transactions (whether they are exempt or not), we can pull them up within QuickBooks. 

Go to the Taxes menu. On the VAT page, click the View reports drop-down button. Then, select the report you want to see. 

Regarding the corporate tax, QuickBooks Online doesn't support the calculation for corporate tax. We only support VAT and PAYE taxes for payroll. 

Though, you can record your corporate taxes inside QuickBooks using a bill, a cheque, or an expense entry. You would still want to manually calculate it however. 

There might be a third-party app that would help you calculate corporation tax within QuickBooks. So, I'd recommend browsing for offers in the App Centre page (ensure the flag or region is set to UK): https://quickbooks.intuit.com/app/apps/home.

I would, however, recommend consulting a tax adviser or an accountant in calculating your corporation tax. They'll ensure it is accurate and properly booked in QuickBooks.
