How do I edit my box 4 on my vat return

Hi @matt.optimumph,

This is possible in the Prepare VAT return page.

Follow these steps:

1. Click the Taxes tab.
2. Locate the VAT return in question under the VAT tab, then tap Prepare return.
3. Scroll down and look for Box 4 and press the Adjust link on the right side. 
4. Enter the necessary changes.
5. You can then press Submit to HMRC for an online submission, or hit the right side menu to Mark as filed.

You can keep this article for future reference: Adjust your VAT liability. It has the steps on how you can edit your VAT liabilities from boxes 1 through 9. 

Let me know if you have any other questions about VAT in your QBO company, and I'll take care of it for you.
